In order to achieve the above object, the utility model provides a pair of disk seat compensation sealing device of rotatory ball formula three-way commutator mainly includes: the connecting pipe, the elastomer, the sealing valve seat, the rotary ball, the valve body, the flange and the bolt. The valve body is a three-way channel, flanges are respectively arranged on the inlet channel and the two outlet channels, a rotating ball is arranged at the intersection of the three channels in the valve body and is connected with the end part of the connecting pipe, a groove is formed in the end face, connected with the rotating ball, of the connecting pipe, the connecting pipe and the rotating ball are sealed through an elastic body and a sealing valve seat, and the sealing valve seat and the elastic body are sequentially arranged in the groove of the connecting pipe.
The passage of the valve body consists of an inlet passage and two outlet passages.
The flange is connected with the connecting pipe through a bolt.
The sealing valve seat is connected with the rotary ball, and the elastic body is arranged at the bottom in the groove.
The elastic body is arranged at the bottom of the groove and is arranged between the connecting pipe and the sealing valve seat.
In particular, the elastomer is a metal disc spring which has a long-lasting elastic compensation effect, lasting more than 5 years.
Particularly, the elastomer ensures that the sealing valve seat can be tightly attached to the rotary ball for a long time, the sealing performance is good, the friction between the sealing valve seat and the rotary ball is weakened, the service life of the sealing valve seat is ensured to be long, and the labor cost for replacing parts is reduced.
Compared with the prior art, the utility model discloses there are following technological effect:
1. the utility model discloses disk seat compensation sealing device is metal belleville spring through setting up the elastomer, and metal belleville spring has the effect of the elastic compensation of longer time, has solved the problem of elastomer material effectively.
2. This practical disk seat compensation sealing device, elastomer make sealed disk seat can guarantee for a long time to hug closely the roating ball, have solved the elasticity compensation time problem after the disk seat wearing and tearing effectively, have just avoided simultaneously because of the wearing and tearing of disk seat causing the problem emergence of bits contaminated material of wearing and tearing.
3. This practical disk seat compensation seal device through weakening the friction of sealed disk seat and ball, has solved the short problem of disk seat elastomer life effectively, has just avoided simultaneously frequently changing the elastomer because of the elastomer life-span is short to the cost problem that produces and increase workman intensity of labour's problem take place.
