Ventilation valve for liquid filter

The present invention relates to an exhaust valve of a liquid filter, wherein the liquid filter has an exhaust valve connected outside the filter cartridge, and a valve body is provided in the exhaust valve for pushing the closed pressure guide hole by using a spring, and filtering When the gas pressure inside the cylinder is greater than the spring pressure, the gas can push the valve body out of the technical field of the filter cartridge.

For the first press, please refer to Fig. 1 , [ is a schematic diagram of the pressure-reducing pressure of the liquid filter used in the prior art]; refers to a chemical liquid pool 10 for industrial processing such as pickling, electroplating and lamination, and a liquid filter 20 The purpose is to circulate and filter the liquid medicine a0 in the liquid medicine tank 10, so that the sludge and particles generated after the liquid medicine a0 is used can be filtered out by the liquid medicine filter 20, thereby prolonging the service life of the liquid medicine a0. Then, the chemical liquid filter 20 filters the sludge and the fine particles in the chemical liquid a0 according to the filter material 202 in the filter cartridge 201, and the filtered chemical liquid a0 is returned to the chemical liquid pool 10. However, the filtered sludge and particles must block the filter material 202, and the filter material 202 is clogged after use, and the pressure inside the filter cartridge 201 is suddenly increased, and the chemical gas accumulated in the liquid a0 is also in the filter cartridge 201. The internal pressure is increased to the point where the gas explosion is dangerous. Therefore, the chemical filter 20 monitors the chemical gas pressure inside the filter cartridge 201 by using the pressure gauge 30. If the gas pressure inside the filter cartridge 201 is found to be excessive, the pressure relief switch 40 is opened. The chemical gas in the filter cartridge 201 is discharged according to the pressure release switch 40. Therefore, the filter cartridge 201 is in danger of explosion, and then the filter cartridge 201 is removed to replace the filter material 202 (the most dangerous and toxic one among the current chemical gases). One is: cyano gas. In addition, sludge and particles are not drawn and labeled here.

However, because the replacement cost of the filter material 202 is extremely high, the user often uses the liquid filter 20 excessively in order to save costs, thereby increasing the risk of gas explosion of the chemical gas. In addition, whether the operation staff of the liquid chemical filter 20 monitors the value of the pressure gauge 30 is also a big concern, and the operating staff operates the filter cartridge 201 to discharge pressure on time, or operates the filter cartridge 201 when the chemical gas pressure value is too large. Pressure, it is not necessary to mention.

According to the above, it is known that the chemical gas in the filter cartridge 201 is released from pressure, and it is necessary to unscrew the pressure relief switch 40, so that the pressure relief switch 40 has a gas explosion hazard if it is opened or not opened. Therefore, only the problem of the chemical gas explosion risk of the filter cartridge 201 can be solved to effectively guarantee the production conditions of the processed articles.

In view of the above, it is known that there is a danger of gas explosion when the pressure relief switch is opened or not opened when the pressure relief switch is opened or not opened, so that the creator is completely motivated.
