CN202851982U - Vent valve - Google Patents

Abstract

The utility model discloses a vent valve which comprises a valve body and a valve rod which is arranged on the valve body. A valve core is arranged at one end of the valve rod. The valve core is in a tapered shape. The end portion of the valve core abuts against a passage of the valve body to form sealing. A convex body is arranged at the end portion of the valve core. An included angle between the convex body and the valve core is 30 degrees to 45 degrees. The vent valve has the advantages of being simple and skillful in structure and capable of prolonging service life of products and improving sealing performance of the products.

Description

Outlet valve

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, causes seepage, causes unusual inconvenience to use, has reduced usability and sealability, haves 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 improves working life and the sealability of product greatly, and 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 product.

To achieve these goals, the technical solution of the utility model is as follows:

Outlet valve comprises valve body and the valve rod that is arranged on the valve body, and it is characterized in that: an end of described valve rod is provided with spool, described spool is tapered, passage on its end and the valve body offsets and forms sealing, and the end of described spool is provided with convex body, and the angle between described convex body and the spool is the 30-45 degree.

Further, described spool is made with nylon material.

Further, the angle between described convex body and the spool is 35 degree.

Further, the angle between described convex body and the spool is 40 degree.

The setting of this structure, can greatly improve working life and the sealability of product, spool is made with nylon material, in addition, is provided with convex body in the end of spool, angle between described convex body and the spool is the 30-45 degree, the setting of this convex body, can with the passage of valve body on offset at first, and form fabulous sealability, convex body can increase the thickness of sealing, improves sealability.

Simultaneously, convex body can be up and down, in the use, improves whole spool working life, is beneficial to long-run development.

The beneficial effects of the utility model: the utility model exquisiteness simple in structure, working life and the sealability of raising product.

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;

Embodiment

As shown in Figure 1, 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, described spool 3 is tapered, passage on its end and the valve body 1 offsets and forms sealing, and the end of described spool 3 is provided with convex body (among the figure for illustrating), and the angle between described convex body and the spool 3 is the 30-45 degree.

Further arrange, described spool 3 usefulness nylon materials are made.

Further arrange, the angle between described convex body and the spool 3 is the 30-45 degree, and best angle is 35 degree or 40 degree.

As from the foregoing, the utility model exquisiteness simple in structure, working life and the sealability of raising product.

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.
