Valve in the fluid system, used to control the direction of the fluid, pressure, flow device. Valves are devices that allow the flow and stop of the media (liquid, gas, powder) in the piping and equipment and control their flow. The valve is the control component in the pipeline fluid delivery system. It is used to change the cross-section of the passage and the flow direction of the medium. The valve has the functions of diversion, cut-off, throttling, checkback, shunt or overflow pressure relief.
　　
Valves of the one-way valve to transform the original valve using F4 material, easy to wear sealing surface, low life expectancy, is now changed to PEEK (polyetheretherketone) plastic valve. See its technical performance. One-way valve assembly technology requires one-way valve and valve sealing surface shall not be scratches, corrosion and other defects; sealing surface of the hand-grinding sieve sand, after the return of the test with a leak of 5 minutes, no drop-like leakage; There is corrosion, fatigue and other phenomena, in order to ensure the opening of the valve force; on the valve seat sealing surface damage, the first machining, and then manual grinding; stem and seat connections plus anti-pin, and lock the nut; Valve lift from 30.5mm to 60.5mm, in order to improve drainage.
　　
Solve the problem of outlet check valve sleeve rotation In the long-term work, due to the influence of temperature and pressure, the pressure sleeve preload decreases, resulting in rotation, the displacement of the sleeve outlet and the pump outlet, reducing the liquid outlet area. The improved measure is to add anti-loose pins between the sleeve and the gland to prevent the sleeve from rotating and improve the drainage volume.
　　
Gear oil pump caused by low hydraulic jumping I used the method of pressure wire, measured the gear side clearance and radial clearance were 0.25mm and 0.35mm, and technical requirements are quite different, then according to the requirements of the gear gap adjusted to the side Clearance 0.08mm, radial clearance 0.10mm, to solve the problem of low oil pressure pump.
　　
Optimize process procedures Strict implementation of job inspection system to control the opening of the import control valve, exhaust tank in time the residual gas to further improve the drainage.
　　
Liquid ammonia pump displacement and operating cycle based on the original have been greatly improved, reducing the number of reversing, parking, reducing maintenance workload, reducing the consumption of spare parts, spare parts for the safety, stability, long Cycle run laid the foundation.
