Abstract

The invention discloses an anti-explosion angle valve capable of resetting quickly and a working method. The anti-explosion angle valve comprises an angle valve body, an anti-explosion device and a switch valve element. The angle valve body is provided with a water inlet channel and a water outlet channel. The anti-explosion device is mounted on the water inlet channel and comprises an anti-explosion sealing element capable of closing the water inlet channel under the action of a water pressure difference, and the anti-explosion sealing element can move between an opening position of opening the water inlet channel and a closing position of closing the water inlet channel; and the switch valve element can move the anti-explosion sealing element from the closing position to the opening position to be reset. The anti-explosion angle valve has the beneficial effects that the switch valve element move the anti-explosion sealing element from the closing position to the opening position to be reset, so that the anti-explosion sealing element is quick to reset, simple and convenient, and can be reset without detaching the angle valve body.

Description

technical field

[0001] The invention relates to an explosion-proof angle valve capable of quick reset and a working method. Background technique

[0002] Existing explosion-proof angle valve, as Chinese invention patent announcement number is CN205026108U, the patent name is a patent of a kind of novel explosion-proof angle valve, and its explosion-proof device is installed in the water inlet pipe interface, although this explosion-proof device has explosion-proof function, can't prevent explosion-proof To reset the explosion-proof device, the entire angle valve needs to be removed to reset the explosion-proof device. The reset process is too complicated, time-consuming and labor-intensive. Contents of the invention

[0003] The invention provides an explosion-proof angle valve capable of quick reset and a working method, which overcomes the existing disadvantages of the background technology. One of the adopted technical schemes that the present invention solves its tech...
