Problems solved by technology

[0005] Due to the adoption of the above scheme, it is not difficult to draw the following conclusions: the present invention is reasonable in process and ingenious in conception, and the arched seal of the automatic drain valve manufactured directly uses the elasticity and arch of the seal material as the back pressure, making the best use of everything. The structure is simple, which effectively overcomes the defects of the complex structure of the traditional technology, and is of great promotion value

Embodiment Construction

[0008] A manufacturing process of an arched sealing part of an automatic drain valve mainly includes the following steps: A. providing a body made of elastic material; B. making the end surface of the body arched. The structure of the arch seal of the automatic drain valve manufactured by the present invention will be further described in detail below in conjunction with the accompanying drawings. An arch seal of an automatic drain valve is composed of a body 10 made of elastic material, and the end surface of the body 10 is arched. The working principle is briefly described below. When water enters the valve body, the water pressure in the body rises, and the arched seal deforms to block the outlet of the drain valve joint. When the valve body is closed, the water pressure in the body drops, the arch seal recovers, and the drain valve joint drains water.

Abstract

The invention discloses a preparing craft of vaulted sealing element of automatic drainage valve, which comprises the following steps: A, producing a body with elastic material; B, producing the end face of the body as archy. This invention possesses reasonable craft, good idea and simple structure, which can be spreaded widely.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a manufacturing process of an automatic opening and closing control part of a drain valve. Background technique [0002] Currently known fire hydrant automatic drain valves basically utilize springs to provide back pressure. When the water pressure in the valve body is high, the water pressure overcomes the spring force, and when the water pressure is low, the spring force overcomes the water pressure, thereby automatically opening and closing the drain valve, and its structure is complicated. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process for the arch seal of the automatic drain valve that can effectively overcome the above-mentioned defects and provide back pressure to automatically open and close the drain valve. [0004] In order to achieve the above object, the present invention adopts the following...
