Abstract
The utility model discloses an automatic drain valve with high-pressure resistance, which is mainly composed of valve body and junction of the drain valve. The utility model is characterized in that: sealing ring of the junction of the drain valve is connected with an arch-shaped sealing element in which a steel sheet is inlayed. Moreover, the utility model with proper structure and artful design utilizes directly elasticity and arch of the sealing element material as back pressure. Due to the good utilization of resources and simple structure, the utility model overcomes effectively defects resulting from complex structure of traditional technique and exhibits significance of popularization.
Description
Technical field
The utility model relates to valve technology field, specifically, relates to a kind 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 purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, utilizes arched sealing member that the high measuring body automatic drain valve of counterpressure is provided.
For achieving the above object, the utility model adopts following technological scheme: a kind of high measuring body automatic drain valve, mainly be made up of valve body and drain cock joint, it is characterized in that: the seal ring of drain cock joint links to each other with an arched sealing member, and arched sealing member is embedded with a steel disc.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, is skillfully constructed, 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 utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
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.
