Abstract
The invention discloses a preparing craft of automatic drainage valve with high against pressure, which comprises the following steps: A, providing a vaulted sealing element with the seal ring of the drainage valve joint; connecting the vaulted sealing element to the seal ring of the drainage valve joint. B, providing a steel sheet in the vaulted sealing element. This invention possesses reasonable craft, good idea and simple structure, which can be spreaded widely.
Description
Technical field
The present invention relates to technical field of valve manufacturing, specifically, relate to a kind of manufacturing process of drain valve.
Background technique
Present known fire hydrant automatic drain valve all is to utilize spring that counterpressure is provided basically.When hydraulic pressure was high in valve body, water pressure overcame spring force, spring force overcomes water pressure when hanging down, thus the automatic on-off drain valve, its complex structure.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, utilize arched sealing member that the manufacturing process of the high measuring body automatic drain valve of counterpressure is provided.
For achieving the above object, the present invention adopts following technological scheme: a kind of manufacturing process of high measuring body automatic drain valve mainly comprises following steps: the seal ring of A. drain cock joint provides an arched sealing member coupled; B., one steel disc is provided in the arched sealing member
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: technology of the present invention is reasonable, be skillfully constructed, the high measuring body automatic drain valve that produces, directly utilize the elasticity and the arch of sealing member material to make counterpressure, make the best use of everything, simple in structure, overcome the baroque defective of conventional art effectively, had promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is the structural representation of the high measuring body automatic drain valve that produces of the present invention.
Embodiment
A kind of manufacturing process of high measuring body automatic drain valve mainly comprises following steps: the seal ring of A. drain cock joint provides an arched sealing member coupled; B., one steel disc is provided in the arched sealing member.The structure of the high measuring body automatic drain valve that the present invention is produced below in conjunction with accompanying drawing describes in further detail.A kind of high measuring body automatic drain valve mainly is made up of valve body 3 and drain cock joint 1, and the seal ring of drain cock joint 1 links to each other with an arched sealing member 2, and arched sealing member 2 is embedded with a steel disc.Its working principle of brief description is worked as valve inleting water, and hydraulic pressure raises in the body, the outlet that drain cock joint is blocked in the arched sealing member distortion.When valve body is closed, hydraulic pressure descends in the body, and arched sealing member is replied, the drain cock joint draining.
Claims (1)
1, a kind of manufacturing process of high measuring body automatic drain valve mainly comprises following steps: the seal ring of A. drain cock joint provides an arched sealing member coupled; B., one steel disc is provided in the arched sealing member.
