Gas heater control valve classified by connection

(1) screw type (tube) installation and connection. Gas Heater Control Valve ports connecting screw fittings and pipes and other components, and thus fixed in the pipeline. This approach applies to simple hydraulic system.

(2) screw-mounted connection. Each port gas control valve are arranged in the same mounting surface, and there is a corresponding fixed oil port connecting plate with screws and Heater Gas Valve, and then pipe fittings and pipe connections with other elements; or put a few in a gas control valve with screws manifold

On different sides of the punch in the manifold, each valve is composed of communication loop. When removing the gas control valve due to other components without removing connected, so this installation connection broader application.

(3) Modular installation and connection. Below the gas control valve connection joint surface, the oil ports respectively in these two surfaces, and the same size gas control valve ports connected to the same size. Each gas control valve in addition to its own function, but also play a role in the oil passage, the gas control valve will be stacked into each other loops, no pipe connections, so the structure is compact, small pressure loss.

(4) Flange mounting connection. And screw connection similar, but instead of flanged screw fittings. For Path! 32_ or larger flow systems. Its high strength, reliable connection.

(5) cartridge installation and connection. No separate body such Propane Control Valve, unit body from spool and sleeve and other components of the cartridge in the pre-hole block, connecting screws or the cover plate, and within a block passage through the various gas control valve connected to form a circuit block plug body and play a role in the pipeline. This is a new way to adapt to the installation and connection of the hydraulic system integration and developed.

A threaded classification
1. thread since the beginning of two kinds of internal and external threads;
2. Press the tooth shape can be divided into: 1) triangular thread 2) trapezoidal thread 3) rectangle thread 4) serrated thread;
3. Press the line fractal single thread and multiple thread;
4. Press the right-hand thread screw-direction points and two left-hand thread, dextral not marked, plus L-LH, such as M24 × 1.5LH;
5. Press uses different points are: Metric common thread, threaded Gas Grill Control Valve thread sealing, non-threaded gas heater control valve thread sealing, 60 ° tapered pipe thread, Metric taper thread, etc.
Two Metric common thread
1. Metric common thread with a capital M, said tooth type angle 2α = 60 ° (α, said tooth-type half-width);
2. Metric common thread pitch divided by the common thread of two coarse thread and fine teeth;
2.1 coarse gas heater valve thread pitch mark is generally not indicated, such as M20, said coarse thread; fine thread pitch mark must be identified, such as M30 × 1.5 represents fine thread, where the pitch is 1.5.
2.2. The common thread for the connection between gas patio heater valve mechanical parts and fastening, multi-threaded connection generally coarse thread, than the same nominal diameter of coarse thread fine thread strength is slightly higher, better self-locking performance.
Mark 3. Metric ordinary thread: M20-6H, M20 × 1.5LH-6g-40, where M represents the common thread Metric, 20, said the thread Gas Heater Control Valve nominal diameter 20mm, 1.5 represents pitch, LH, said L, 6H, 6g, said thread accuracy class, upper class code represents precision internally threaded lower accuracy level code, said external thread, 40, said screwing length

Gas Heater Valve installation and maintenance of way

The installation and maintenance of way
Prevention of leakage of pipe joints in the gas heater valve, both the metal pipe coupling, or Oven Gas Valve, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipe by a large external force or impact, so that the card sleeve loose or deformed pipe ends and cause leakage, you should check whether the card holder out of round, whether the defect edge, whether the pipe end in good condition and the extent of compression ferrule nut, while also eliminating external piping. For flared Gas Heater Control Valve, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front end truncated. If the top male and female cones pressure seal, which is mostly due to two cone leak damage, available grinders for grinding cone. In some by "о" or outer-ring seal by the end face of the gas heater valve, the leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that the two-plane connection when the pressure is uneven or "о" ring is cut cause leakage; "о" ring uncompacted, insufficient amount of elastic deformation caused by leakage; "о" mouth-ring groove just too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, can also be sealed with a flat opening slot stop cutting or grinding to reduce the groove depth of mouth only, so "о" ring has sufficient amount of elastic Gas Control Valves (compression in general should be between 0.35-0.65mm). For the use of oil and rubber, wool felt, soft steel cardboard combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.

Card sets of gas heater valve installed

(1) according to the requirements of Chapter 9 of the need for pickling pipes should be pickled;
(2) according to the required length by sawing or patio heater gas valve  machines and other equipment off the tube, and definitely not broken with solvent (such as flame cutting) or cutting wheel; remove the tube ends inside and outside round burrs, metal chips and dirt; removing rust-proof pipe fittings agents and dirt; but also to ensure the pipe roundness;
(3) the nut, ferrule has set into the tube, card sets Gas Control Valve the front edge (diameter end) from the mouth of the tube at least 3mm, then taper pipe into the connector body, until the top;
(4) Slowly tighten the nut, turn the gas safety burner valve until it does not move, then tighten the nut 2 / 3-4 / 3 laps;
(5) Remove the check card sets whether to cut the pipe, the location is correct. Card sets are not allowed to move axially to slightly rotate;
(6) Tighten the nuts again after passing inspection.

Soda valve usage summary

Due to the special nature of soda ash industry, all juggling various soda ash business in the valve using the system on, both to resolve its internal leakage problems, but also to solve the leakage problem, but also to overcome scarring, clogging and erosion and other problems with crystallization . Through many years of cooperation with the soda companies, the actual depth, continuous improvement, Valve Manufacturing Co. finally succeeded in developing a fourth-generation soda special eccentric valve, completely solve the above problems Soda normal production management.
1. Currently the use of alkali enterprises pilot valves valve soda companies use are: ball valves, plug valves, globe valves, slurry valves and other materials are mainly: carbon steel, stainless steel, molybdenum, titanium II. Their common feature is the use of short cycle, easily, the leakage. Endoleak making it difficult to cut and control, such as carbonation tower when you want to cook plus many blind plate, resulting liquor leakage, corrosion around the device, increasing labor load. In and pumps, AII pumps, heat pumps, etc. lye overhaul was forced off due to inability to process short-term parking, resulting in the production of passive. Leakage increase the difficulty of site management, hang everywhere "Paste child", taking into account the on-site management, to regularly wash, environmental problems difficult to solve. Scarring caused because the system can not be cut off valve, part of the valve (slurry valves, etc.) and other equally time-consuming switch to normal production management brings many difficulties. Frequent valve repair and replacement, so run, run, drip, leak increases.
Therefore, all soda ash production management personnel, operators, maintenance personnel are feeling due to a Heater Gas Valve problem and brought a lot of work inconvenience.
