Meaning continuous improvement where hydraulic valve

With the study of the safety valve, safety valve structure to improve and perfect performance, provides a valuable theoretical and practical basis, in order to ensure stable operation of hydraulic support, fully mechanized coal face of production safety have some practical significance for hydraulic support . Hydraulic support as a safety valve control system, the key element to maintain the entire stent system safe and efficient operation. So for the design of safe, reliable, durable and high flow valve has been the focus of scientific research today, the gas brass safety valve for the study conducted a comprehensive study. Liquid flows through the orifice in the maximum speed, the opening of different size and pressure of the overflow speed also has the most direct impact.
With the increase of inlet pressure, flow speed increases, the minimum pressure at the orifice becomes smaller, and thus prone to cavitation, whirlpool and so on. The larger and smaller openings of the pressure, at maximum speed, the greater the orifice. Safety valve pressure drop is mainly distributed in the orifice at the orifice in the vicinity there is a clear area of ​​low pressure, and the smaller the opening degree, low pressure is smaller; the greater the pressure, the low pressure is smaller.
