Gate Valve The discharge capacity of a Gate Valve, that is, the engine, is one of the most important indicators to measure the performance of a Gate Valve. In the "Online Function and Gate Valve and Testing System" patented technology, open valve dynamic displacement measurement issues and related flow mechanisms are studied under the guidance.
Main content: Nozzle flow field characteristics and basic equations of ideal gas for isentropic flow in fluid control, derived formulas to calculate the discharge amount of Gate Valve opening, and systematically summarized the discharge capacity factors of opening relief valves. Overpressure Gate Valve present interactive processes, especially changes in gas dynamic parameters.
In experimental studies, flange and valve core sensors were used to detect sensor testing engine and other field related parameters. Displacement calculations were performed using two-dimensional and three-dimensional numerical simulations and experimental results, and the study showed similar simulation and experimental results using a special sensor to test and measure emissions with good fluidity. With appropriate treatment of displacement in numerical simulations, Gate Valve capabilities can be predicted more accurately.
The
Universal Valve solves the problem of low adjustment accuracy. This Universal Valve includes a valve body and a tubular upper cover with a handwheel. The valve body and the upper cover are fixedly connected. The handwheel is set at the top of the outer cover of the upper cover and has several positioning notches distributed at intervals. The cover and the handwheel Zhijian has positioned the positioning piece and the handwheel to press the positioning piece to position the positioning piece in the notch. The handwheel can lead the rotation of the positioning piece from the next positioning notch to the positioning piece, the upper cover and the valve body. Zhijian has a sealing sleeve. The sealing sleeve allows the cavity of the valve body to communicate with the non-cavity in the cover. The cover function has a spring. The spring opposes the other end of the film to reach the other end of the sealing sleeve. The sealing sleeve is always cut off. The tendency of the valve to close.
Universal Valve with high sealing performance adjustment spring pressure accuracy. It has online monitoring and Universal Valve and inspection functions. It is characterized by: There is an adjusting nut in the fixed top convex body of the valve body. The adjusting nut has a pressure rod and a hollow-formed pressure rod with a summer opening at the bottom. It has a spherical structure and a flat structure, and the top The pressure rod and the bottom of the pressure rod arrive to receive the spring seat on the top cone and the valve rod is inserted into the cavity of the pressure rod; the pressure rail is located at the top with a powerful sensor or fastening bolt; protruding against the adjusting nut The lock nut is fastened to the valve body and there are also fixed lock nuts at the top of the top view of the adjusting fastening nut; there are at least two screw holes for fixing screws on the upper surface of the body of the valve.
