Abstract
The utility model discloses a novel air release valve which comprises a valve body and a valve rod arranged on the valve body. A groove is formed in a rod body of the valve rod. A sealing ring is arranged inside the groove. The novel air release valve is simple and ingenious in structure, and capable of avoiding safety loopholes under the condition that a product is opened, improving application safety factor, improving sealing performance, and prolonging service life of the sealing ring.
Description
Technical field
The utility model relates to a kind of Novel vent 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 Novel vent valve, there are many deficiencies, complex structure, wherein; between valve rod and the valve body, do not have seal protection, using in the situation of opening, product is to be in the semitight state; therefore there is very large potential safety hazard, integral body used have hidden danger, 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 Novel vent valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, the potential safety hazard of having avoided product to occur in the situation of opening improves and uses safety coefficient, also improves sealability simultaneously, prolong the working life of seal ring, this case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel vent valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure, the potential safety hazard of having avoided product in the situation of opening, to occur, improve and use safety coefficient, also improve simultaneously sealability, prolong the working life of seal ring.
To achieve these goals, the technical solution of the utility model is as follows:
Novel vent valve comprises valve body and the valve rod that is arranged on the valve body, and it is characterized in that: the body of rod of described valve rod is provided with groove, is provided with seal ring in the described groove.
The setting of this structure, seal ring form sealing between valve rod and valve body, even when not using, also can form sealing, protection product safety coefficient in use.
Further, the degree of depth of described groove is d, and width is L, and the cross-sectional diameter of seal ring is D, wherein, and 0.65≤d:D≤0.85,0.5≤L:D≤1.
Further, described d:D equals 0.7.
Further, described L:D equals 1.
The utility model is studied the ratio between seal ring and the groove, and adjust, compared with prior art, the seal ring tightness of this product is high, and the degree of adaptability between seal ring and the groove is good, seal ring in use, suffered pressure extremely cooperates closely with groove so that seal ring forms ellipse, forms interference fit, also form and cooperates closely simultaneously with between the valve body, greatly improve sealing.
If seal ring is too small, often can form sealing in the early stage, but service time one is of a specified duration, the gap will appear, and aging speed is fast, and working life is not long, and this client makes troubles.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, the potential safety hazard of having avoided product to occur in the situation of opening improves and uses safety coefficient, also improves sealability simultaneously, prolongs the working life of seal ring.
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 Novel vent valve, comprises valve body 1 and the valve rod 2 that is arranged on the valve body 1, and it is characterized in that: the body of rod of described valve rod 2 is provided with groove 3, is provided with seal ring 4 in the described groove 3.
Further arrange, the degree of depth of described groove 3 is d, and width is L, and the cross-sectional diameter of seal ring 4 is D, wherein, 0.65≤d:D≤0.85, optimal proportion is 0.7,0.5≤L:D≤1, optimal proportion is 1.
As from the foregoing, the utility model exquisiteness simple in structure, the potential safety hazard of having avoided product to occur in the situation of opening improves and uses safety coefficient, also improves sealability simultaneously, prolongs the working life of seal ring.
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.
