SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a single-action wear-resisting piston seal possesses sealed effectual advantage, has solved current device and has not had auxiliary stay, can't support it, and the sealing washer is very easily out of shape after long-time the use, the not good problem of life.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a wear-resisting piston seal of nonoculture, includes main part and support frame, wherein the support frame is all installed with interior bottom at the top in the main part, the main part is inside to be equipped with the gas injection hole in the middle of being close to the surface, the main part internal surface is equipped with the inside groove, be equipped with the boss in the middle of the main part surface, the main part surface is located the boss upper and lower surface and all installs the recess, the main part surface is close to the top and all is equipped with the bearing diagonal platform near the bottom.
Preferably, one side of the support frame, which is close to the inclined strut table, is in a shape of a Chinese character 'hui', and the support frame is used for supporting the inclined strut table through the shape of the Chinese character 'hui'.
Preferably, the main body is internally provided with a spring at the position of the boss, and the boss is elastically supported by the spring.
Preferably, the inner surface of the inner groove is provided with a reinforcing rib, the reinforcing rib is spirally arranged, and the deformation rate of the main body is reduced by arranging the reinforcing rib.
Preferably, the main part adopts the butadiene acrylonitrile rubber to make, improves the utility model discloses a performance.
Preferably, the gas injection nozzle is installed on one side of the gas injection hole on the inner surface of the main body, and gas is injected into the gas injection hole through the gas injection nozzle.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model discloses a top all sets up the support frame with interior bottom in the main part, reaches the effect that supports the sealing washer, is the setting of returning shape near bracing platform one side at the support frame to solve no auxiliary stay, can't support it, long-time use back sealing washer is very easily out of shape, the not good problem of life has improved the support intensity of sealing washer, and then has improved the life of sealing washer.
2. The utility model discloses a set up the gas injection hole in the middle of the inside surface that is close to of main part, reach and carry out the effect that gas supported to the sealing washer, lie in gas injection hole one side at the main part internal surface and set up the gas injection mouth to when the solution temperature is higher, can't carry out gas support to the sealing washer, the not good problem of sealing washer sealing performance has improved the sealing performance of sealing washer, thereby has guaranteed the sealed effect of sealing washer.
