Abstract
The utility model discloses a spiral snap ring for a valve. The spiral snap ring is round and externally equipped with a fixing surface and provided with a screw thread on the inner wall; and the upper port of the spiral snap ring is in a necking shape, and an anti-abrasion layer is arranged on the surface of the fixing surface. The spiral snap ring has a simple and smart structure and good rotation and fixation effects; greatly improves the performance of the product, and prolongs the service life of the product.
Description
Technical field
The utility model relates to a kind of for the spiral snap ring on the 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 valve, when being connected to water pipe or other pipelines, the spiral snap ring need to be installed carefully, leaks otherwise have, and causes and need to reinstall, and reduces working efficiency.Simultaneously, also more loaded down with trivial details when disassembling, be unfavorable for long-run development.
Spiral snap ring on the existing valve, service time one is of a specified duration, skidding can occur when rotating fixedly, so that product is worn, reduces usability and working life.
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 ofly for the spiral snap ring on the valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, the rotation good fixing effect, greatly enhance product performance simultaneously, increase the service life, this case produces thus.
The model utility content
It is a kind of for the spiral snap ring on the valve that the purpose of this utility model is to provide, and can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, and the rotation good fixing effect is enhanced product performance simultaneously greatly, increases the service life.
To achieve these goals, the technical solution of the utility model is as follows:
Be used for the spiral snap ring on the valve, described spiral snap ring is circular, and the outside is provided with stationary plane, and inwall is provided with screw thread, it is characterized in that: the upper end-hole of described spiral snap ring is a reducing shape, is provided with wearing layer on the surface of stationary plane.
The setting of this structure is beneficial to installation, is provided with wearing layer on the surface of stationary plane, so just is beneficial between spanner and the stationary plane non-sliply, raises the efficiency.Since non-slip, the loss of spiral snap ring also just reduced, prolong its working life.
Upper end-hole at the spiral snap ring is a reducing shape, is beneficial to the chucking that cooperates that improves between pipeline and the valve, water leakage phenomenon can not occur.
Further, excessive with circular arc between described stationary plane and the stationary plane.
The setting of this structure is beneficial to the attractive in appearance of integral body.
Further, described stationary plane is arranged on the middle part of spiral snap ring outer wall.
The setting of this structure, fixedly the time, the stressed impact for product of stationary plane is little at spanner, and it is even to share power, reduces the loss of stationary plane, and then improves whole usability and working life.
The setting of this structure, the aesthetics of integral product and fastness are beneficial to long-run development.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, the rotation good fixing effect is enhanced product performance simultaneously greatly, increases the service life.
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 for the spiral snap ring on the valve, and described spiral snap ring is circular, the outside is provided with stationary plane 1, inwall is provided with screw thread, it is characterized in that: the upper end-hole 2 of described spiral snap ring is a reducing shape, is provided with wearing layer 3 on the surface of stationary plane 1.
Further arrange, excessive with circular arc between described stationary plane 1 and the stationary plane 1.
Further arrange, described stationary plane 1 is arranged on the middle part of spiral snap ring outer wall.
As from the foregoing, the utility model exquisiteness simple in structure, the rotation good fixing effect is enhanced product performance simultaneously greatly, increases the service life.
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.
