Abstract
The utility model relates to an arch-shaped sealing element for automatic drain valve, which is essentially composed of a body made up by elastic material. The utility model is characterized in that: head face of the body is arch-shaped. The utility model is of proper structure, ingenious design and simple structure, which directly use of elasticity of the sealing element and the arch as background pressure, overcomes the disadvantage of complex structure of traditional techniques and exhibits great value in popularization.
Description
Technical field
The utility model relates to valve technology field, specifically, relates to a kind of control piece of automatic on-off 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, and counterpressure can be provided, with the arched sealing member of the automatic drain valve of automatic on-off drain valve.
For achieving the above object, the utility model adopts following technological scheme: a kind of arched sealing member of automatic drain valve, mainly form by the body that elastic material is made, and it is characterized in that: the end face of body is arch.
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 arched sealing member of automatic drain valve is made up of the body 10 that elastic material is made, and the end face of body 10 is arch.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.
