Abstract
A valve body sealing structure comprises a valve body, a seal ring and gaskets, wherein the seal ring and the gaskets are located at the port end of the valve body, one gasket is located at the upper end of the seal ring, and the other gasket is located at the lower end of the seal ring; notches are formed in the upper end and the lower end of the seal ring, and the gaskets are provided with bosses matched with the notches in the seal ring; a wave-shaped sealing groove is formed in the annular surface, making contact with the valve body, of the seal ring. According to the technical scheme, the valve body sealing structure is simple in structure, convenient to use and good in sealing effect, thereby preventing leakage.
Description
Technical field
The present invention relates to one to surge relief valve driver.
Background technology
Sealing member is to prevent fluid leakage and preventing introduced contaminants such as dust from invading inside machinery equipment with moisture etc., current valve body link is one piece of cross section is the pad of rectangle, and when operating pressure is bigger, pad can be deformed, making sealing property reduce, fluid is susceptible to leakage.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of simple in construction, easy to use is unlikely to deform and the valve body sealing structure of good sealing effect.
The present invention is by the following technical solutions: it includes valve body, sealing ring and pad, sealing ring and pad are respectively positioned on the interface end of valve body, one piece of pad is positioned at the upper end of sealing ring, one piece of pad is positioned at the lower end of sealing ring, the upper and lower side of sealing ring is provided with notch, the anchor ring being provided with the boss matched with the notch on sealing ring, sealing ring and valve body contact on pad is provided with the seal groove of undulate.
The interface end of valve body is sealed by the present invention by sealing ring and pad, it is unlikely to deform, the upper and lower side of sealing ring coordinates with boss each through notch, seal, make its good sealing effect, corrugated seal groove, it is possible to further increase sealing property, to play multi-layer sealed effect, hence it is evident that improve sealing effectiveness.
Owing to have employed technique scheme, the simple in construction of the present invention, easy to use, it is unlikely to deform, good sealing effect, it is therefore prevented that the generation of leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In conjunction with accompanying drawing, the present invention is further explained.
As shown in Figure 1, the present invention includes valve body 1, sealing ring 2 and pad 3, sealing ring 2 and pad 3 are respectively positioned on the interface end of valve body 1, one piece of pad 3 is positioned at the upper end of sealing ring 2, one piece of pad 3 is positioned at the lower end of sealing ring 2, the upper and lower side of sealing ring 2 is provided with notch 4, is provided with the boss 5 matched with the notch 4 on sealing ring 2 on pad 3, and the anchor ring that sealing ring 2 contacts with valve body 1 is provided with the seal groove 6 of undulate.
The interface end of valve body is sealed by the present invention by sealing ring and pad, it is unlikely to deform, the upper and lower side of sealing ring coordinates with boss each through notch, seal, make its good sealing effect, corrugated seal groove, it is possible to further increase sealing property, to play multi-layer sealed effect, hence it is evident that improve sealing effectiveness.
