The plunger type sampling valve

The plunger type sampling valve is a special valve for the double-sealed plunger type sampling valve, which is especially suitable for the sampling and testing of the reaction kettle under easy crystallization condition. It is a kind of testing valve commonly used in chemical production. It is specially designed for testing whether certain materials are put in production to meet the requirements.This valve installation part is different, has the different name.For example, it can be installed at the bottom of the tank as a discharge valve;Mounted on the side, can be used as a feed valve;It can be installed on the pipeline as a jet valve and sampling valve;Install in line: can be used as a dead zone - free shut-off valve.The plunger type sampling valve belongs to the plunger valve in a small body structure of one of the valves.The valve is easy to operate, free to open, flexible and reliable movement, simple plunger assembly and maintenance, reasonable sealing structure, convenient replacement of upper and lower sealing rings, suitable for discharging sediment or viscous fluid.Widely used in chemical, pharmaceutical, pesticide, dyes, food processing industries, etc.

Requirements: high, that is, high requirements, high difficulty, high pressure, the valve body product fine small, valve body import and export distance is close, valve parts fine small, small precision difference between accessories;To meet customer requirements, to meet national standards, valve structure and appearance to achieve accurate, beautiful.These three requirements are met, the valve is in line with the customer use requirements.Valve fine small, its complete components.

The working principle of

After taking the sample, hold the handle tightly in a single hand and rotate clockwise, the handle drives the valve column, the valve head will be pushed into the pipeline, the valve is closed, the valve column is filled with the entire valve body;When sampling, turn the handle counterclockwise and retract the valve head to the valve barrel outlet Angle to ensure the flow, remove sediment and open the valve at the same time.The valve head of the sampling valve is a replaceable part, so it is easy to maintain.Its advantages are not easy to plug, avoid the risk of removing the sampling valve;And to ensure the normal sampling.

Sometimes manual operation is very dangerous in industrial production, and in order to achieve automatic sampling, a remote operation, automatic control device is needed to drive the sampling valve open or close state.This requirement can be achieved by removing the handle of the sampling valve and installing the electromagnetic drive device or pneumatic drive device.Because the sampling valve is only open and close two states, there is no intermediate state between open and close, so the electromagnetic drive device or pneumatic drive device is relatively simple.
