For the installation of spring-loaded safety valves, the first thing to note is that before installing the safety valve, the sealing performance must be tested. If the safety valve

1. Under what circumstances does the safety valve need to be verified? (1) Long-term storage or before the first use (2) Regular calibration (3) Valves with severe damage

1. Sulfuric acid: As one of the strong corrosive media, sulfuric acid is a major industrial raw material that is very common. Sulfuric acid with different concentration and tempera

Check valves, which allow fluid to flow in one direction but prevent it from flowing in the other, are available in a wide range of styles. The variety most appropriate for your pr

The structure of the valve tester can be roughly divided into hydraulic system, electrical control system, movable jaws of the left and right working platforms, hydraulic pressure

JWZ holding pressure type: suitable for flange connection ball valve, globe valve, gate valve, check valve, etc.

The structure of the valve tester can be roughly divided into hydraulic system, electrical control system, movable jaws of the left and right working platforms, hydraulic pressure

Second, select N32-46# ordinary hydraulic oil, N32-46# anti-wear hydraulic oil or 20-30# mechanical oil, inject into the fuel tank, the oil quantity can not be lower than the lower

Valve test benches can be divided into the following types: Cut-off valves, control valves, safety valves, although the standards tested by the valve test bench are different, for

The economic viability of the valve test bench means that it is not only the case that the various valves are tested using various standards at the lowest cost and cost, but it is

Many of the aerospace structural steels of the valve test bench are treated with quenching and tempering to achieve higher anti-fatigue function;

Wear protective equipment before using the valve tester, carefully check the insulation of the circuit, whether the plug and socket are damaged, and whether the socket is tight;
