Ball valves are generally limited by sealing materials, because ball valves are usually formed by some plastic materials, the main principle of ball valves is to rely on metal balls to adjust the gas and liquid under the action of the medium, mainly the extrusion between the metal ball and the plastic valve seat to achieve the effect of adjustment. Between the seats ...

Solenoid valves are selected for different media 1. Corrosive medium: it is advisable to choose plastic king solenoid valve, all stainless steel solenoid valve; For the strong corrosive medium must be selected isolation diaphragm type, such as: neutral medium, it is also advisable to choose copper alloy as the solenoid valve housing material, otherwise, there are often rust chips falling off in the valve housing.

There are intelligent positioners and mechanical positioners for valve positioners, and today we are talking about the latter mechanical positioner, which is the same as the positioner shown in the picture Schematic diagram of valve positioner structure In the figure, the components of the mechanical pneumatic valve positioner are basically explained one by one, and the next thing is to look at it.

Routine maintenance is a planned overhaul before a control valve fails, which can be understood as preventive maintenance and usually includes the following tasks. 1. Stress relief Pipelines can produce various stresses due to improper combination or installation, such as thermal stress caused by high-temperature media, uneven tightening force during installation, etc.

In the past operation of natural gas pressure regulating system, terminal equipment such as pressure regulating cabinets, pressure regulating boxes, and pipelines in the distribution network have always been a relatively weak part of the monitoring means. As a result, problems such as non-troubleshooting and emergency gas shutdown accidents also make consumers and operators feel painful. Meanwhile...

1. Testing and adjustment 1. Whether it is manual, pneumatic, hydraulic or electric, all parts of this product have been seriously debugged before leaving the factory, and the user should uniformly fix both ends of the import and export when re-checking the sealing function Fixed, close the disc valve, apply pressure to the inlet side, and check whether there is any leakage on the outlet side, ...

Pressure testing method for ball valves The strength test of the pneumatic ball valve should be carried out in the semi-open state of the ball. (1) Floating ball valve tightness test: the valve is in a half-open state, one end is introduced into the test medium, and the other end is closed; Turn the ball several times, open the closed end inspection when the valve is closed ...
