Abstract
The utility model discloses an exhaust valve which comprises a valve body and a valve rod arranged on the valve body; a valve core is arranged at one end of the valve rod; and an annular convex body structure is formed at the end part of the valve core and comprises a first convex body, a second convex body and a third convex body which are arranged at intervals in sequence. The exhaust valve has the advantages that the structure is simple and exquisite, and the service life and the sealing performance of the valve rod are prolonged and improved.
Description
Technical field
The utility model relates to a kind of outlet valve.
Background technique
At present, China has been maximum in the world structural material producing country and country of consumption.Main building material product cement, sheet glass, construction sanitary ceramic, stone material and materials for wall Isoquant rank first in the world for many years.Simultaneously, the building material product quality improves constantly, and the energy and raw materials consumption descend year by year, and various building materials continue to bring out, and building material product constantly upgrades.
On existing outlet valve, there are many deficiencies, complex structure, wherein, between spool and the valve body, service time is of a specified duration, and spool is very easy to distortion, and sound construction is inadequate, time one will be caused seepage for a long time, cause unusual inconvenience to use, reduced usability and sealability, have much room for improvement.
As from the foregoing, the problem that exists in the present product is badly in need of solving.
In view of this, the inventor has done deep research to this, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of outlet valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, improve working life and the sealability of valve rod, this case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of outlet valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, working life and the sealability of raising valve rod.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of outlet valve, comprise valve body and the valve rod that is arranged on the valve body, it is characterized in that: an end of described valve rod is provided with spool, is provided with the convex body structure of annular in the end of spool, and described convex body structure comprises the first convex body, the second convex body and the 3rd convex body of successively interval setting.
Further, described spool is made with nylon material.
Further, the height of described the first convex body is greater than the height of the second convex body, and the height of described the second convex body is greater than the height of the 3rd convex body.
The setting of this structure, can greatly improve working life and the sealability of product, spool is made with nylon material, in addition, be provided with the convex body structure of annular in the end of spool, described convex body structure comprises the first convex body, the second convex body and the 3rd convex body of successively interval setting, the setting of this convex body structure, wherein the first convex body can with the passage of valve body on offset at first, and forming fabulous sealability, the pressure that the first convex body bears is large, so the height of the first convex body wants large, can increase the thickness of sealing, improve sealability.The setting of the second convex body and the 3rd convex body, can first convex body service time of a specified duration after, play the replacement effect, prolong the working life of valve rod.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, working life and the sealability of raising valve rod.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model upper valve core.
Embodiment
As depicted in figs. 1 and 2, the utility model relates to a kind of outlet valve, comprise valve body 1 and the valve rod 2 that is arranged on the valve body 1, it is characterized in that: an end of described valve rod 2 is provided with spool 3, be provided with the convex body structure of annular in the end of spool 3, described convex body structure comprises the first convex body 4, the second convex body 5 and the 3rd convex body 6 of successively interval setting.
Further, described spool 3 usefulness nylon materials are made.
Further, the height of described the first convex body 4 is greater than the height of the second convex body 5, and the height of described the second convex body 5 is greater than the height of the 3rd convex body 6.
As from the foregoing, the utility model exquisiteness simple in structure, working life and the sealability of raising valve rod.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
