CJ/T447 Self Closing Gas Cut Off Valve G1/2'' Inlet 1/2'' Outlet

Kitchen gas pipe shutoff gas cut off valve self-closing for Home stove natural gas leakage

Product description:

The pipeline gas self-closing valve produced by our company is a safety emergency shutdown device for gas pipelines. In the process of gas use, it can automatically close the gas pipeline in case of explosion, overhaul, gas outage, resupply, accidental gas outage, low air pressure, high air pressure, pressure rise caused by failure of the pressure regulating box, etc. This product has Good sealing performance, no power consumption, high sensitivity, reliable operation, small size, easy to use, etc. Valve opening must be manually intervened and manually opened to meet safety management specifications and meet the characteristics of accident handling.

17. Implementation standard: CJ / T 447-2014

18. Body material: aluminum alloy

19. Sealing material: Ding Qing rubber.

Working principle:

The self-closing valve drives the small diaphragm by the permanent magnet to attract magnetic components to achieve the purpose of sealing. When the valve is manually opened, the diaphragm moves the magnet under the action of air pressure to cooperate with the transmission component to open the valve to achieve a balanced state. When the inlet pressure exceeds the set value, the diaphragm drives the magnetic element away from the magnet, the magnet returns to its original state, and the valve achieves the purpose of closing.

Fourth, the operating instructions:

1. Opening method under normal pressure:

Close the cooker or the self-closing valve at the rear end of the ball valve, manually pull up the handle for 3-5 seconds, and the valve will automatically remain open after being released.

2. Overpressure emergency treatment plan:

When the red handle of the valve is disengaged from the yellow handle, the valve is in an overpressure state at this time. The rear-end ball valve should be closed immediately to contact the gas company to handle the fault. After the fault is removed, open the ball valve to restore the valve to the closed position, and then open it according to the operation in Article 1 . valve.

3. Undervoltage treatment plan:

When the self-closing valve is in the closed position automatically, please check whether the hose between the valve and the cooker is detached or burst. If there is no such phenomenon, check whether the air inlet pressure is lower than the normal working pressure, and open the valve after venting the fault and normal ventilation.

4. Man-made abnormal valve closing:

If the valve appears to be closed by knocking or pushing the handle during the work, please check the gas pipeline and the valve for damage. After removing the hidden danger, you can open the valve by yourself.

Installation Requirements:

1. The valve installation unit shall have corresponding qualifications.

2. The valve should be installed behind the gas meter and in front of the cooker.

3. It should be installed in the direction of air flow indicated by the valve body, allowing horizontal and vertical installation.

4. When the pipeline is purged, it is recommended to isolate the self-closing valve to prevent debris in the pipe from damaging the valve sealing material.

5. Before performing pressure test to check the sealing performance, the self-closing valve should be opened. The test pressure should not be greater than the maximum inlet pressure of the valve.

6. Why the valve is damaged or the parts are lost due to improper storage or illegal construction are not covered by our free warranty.
