Abstract
The utility model relates to a valve and particularly discloses a quick release valve including a valve cover, a piston body, a valve housing and a base, wherein the valve housing and the base form a sealed cavity by threaded connection; the piston body is arranged in the sealed cavity and divides the sealed cavity into an upper cavity and a lower cavity which are respectively connected with an air source through pipelines; and the valve cover is connected with the piston body through a bolt. The quick release valve has the advantages of long service life, low manufacturing cost and strong corrosion resistance.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of long service life, low cost of manufacture, fast-discharge valve that corrosion resistance is strong.
Background technique
Traditional product mainly is made up of valve gap, valve casing, piston body, base and spring etc., and piston body is divided into two chambers up and down with valve casing, and upper chamber links to each other with source of the gas by pipeline, and spring is housed in the lower chamber, and base is by spring support piston body.Its working principle is: when valve body was closed, spring force acted on piston body, and piston is moved up, and valve gap withstands outage, thereby stoped liquid to be discharged; When valve body was opened, source of the gas was squeezed into upper chamber with pressurized air, and piston is moved down, and valve gap leaves outage, thereby liquid is discharged.There is following shortcoming in this series products: (1) spring is in compressive state for a long time, and can shorten its working life; (2) valve body may be used for the discharging of deep-etching liquid, and spring is corroded easily.Deficiency of the prior art mainly is the application of spring, and its working life is short, corrosion-resistant.The present invention saves spring, and lower chambers is also linked to each other with source of the gas by pipeline, and when valve body was closed, source of the gas was squeezed into lower chambers with pressurized air, and piston body is moved up, and valve gap withstands outage, thereby stops liquid to be discharged.Therefore, the objective of the invention is to increase the working life and the corrosion resistance of valve.
The model utility content
In order to overcome defective of the prior art, the utility model provides a kind of long service life, low cost of manufacture, fast-discharge valve that corrosion resistance is strong.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of fast-discharge valve comprises valve gap, piston body, valve casing, base; Described valve casing and base by thread connect to form a seal chamber; Described piston body is located in the described seal chamber, and the sealing cavity is divided into two chambers up and down, and two chambers link to each other with source of the gas by pipeline respectively up and down; Valve gap links to each other with piston body by screw.
The beneficial effects of the utility model are, owing to adopted technique scheme, the utlity model has long service life, low cost of manufacture, beneficial effect that corrosion resistance is strong.
Description of drawings
Fig. 1 is a longitudinal section of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of fast-discharge valve comprises valve gap 1, piston body 2, valve casing 3, base 4; Described valve casing 3 is formed a seal chamber with base 4 by being threaded; Described piston body 2 is located in the described seal chamber, and the sealing cavity is divided into two chambers up and down, and two chambers link to each other with source of the gas by pipeline respectively up and down; Valve gap 1 links to each other with piston body 2 by screw.
The effect of described valve gap 1 is: when valve cuts out, contact with bottom land, outage is blocked, stop liquid to be discharged; When valve is opened, separate, expose outage, liquid is discharged fast with bottom land; 2 effects of described piston body are: drive it by compressed-air actuated turnover and move up and down, thereby reach the switching of valve body; Described valve casing 3 effects are: form a seal chamber with base 4, take in or discharge pressurized air; Described base 4 effects are: form a seal chamber with valve casing 3, take in or discharge pressurized air.
Working principle of the present utility model is: source of the gas is squeezed into lower chambers with pressurized air, and the pressure of lower chambers increases, and moves upward thereby promote piston body 2, and drive valve gap 1 and move upward, up to contacting, compress, block outage with bottom land, stop liquid to be discharged, realize the closing motion of valve; Source of the gas is squeezed into upper chamber with pressurized air, and the pressure of upper chamber increases, and moves downward thereby promote piston body 2, and drives valve gap 1 and move downward, and up to being separated to maximum with bottom land, exposes outage, and liquid is discharged fast, realizes the opening action of valve.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
