Abstract
The utility model provides a double containment heavy -calibre ball valve has the valve body, the front end of valve body has the water inlet, there is the delivery port rear end of valve body, there is the valve shaft on the valve body, there is the hemisphere case in the one section company of valve shaft in the valve body, have sealed vicely between the interior circumference of hemisphere case excircle week and valve body, case sealing ring on the sealed vice case seal receptacle that has a circumference the case outside and in the valve body body seals on the body seals seat of circumference encircle, the case sealing ring is the metal material sealing ring on the case seal receptacle, the body seals ring is metal material sealing ring and the rubber materials sealing ring on the body seals seat. The utility model discloses a sealed vice have a metal material sealing ring on the case seal receptacle, and the matched with body seals ring is two sealing rings of metal material sealing ring and rubber materials sealing ring on the body seals seat with it, is a double containment heavy -calibre ball valve, the long service life of metal material sealing ring, and the sealing performance of rubber materials sealing ring is good, and sealed vice adjustment is very easy, and it is good to seal vice matched with 0.
Description
Technical field
This utility model relates to a kind of big-diameter ball valve, the sealing pair between valve body and the hemispherical spool of a kind of big-diameter ball valve.
Background technology
The ball valve that bore is 500 millimeters～3000 millimeters is big-diameter ball valve.Big-diameter ball valve has valve body, there is water inlet the front end of valve body, there is outlet the rear end of valve body, valve shaft is had on valve body, in valve body one section of valve shaft is connected with hemispherical spool, sealing pair, sealing pair is had to have the seal spool ring on the seal spool seat of spool excircle and the valve seal ring on the valve seal seat of valve body inner periphery between hemispherical spool excircle and the inner periphery of valve body.
Sealing ring in ball valve sealing pair has the hard sealing ring of metal material and the soft seal ring of elastomeric material.The service life of metal seal ring is long, but sealing property is not fine, and sealing pair adjusts and is difficult to, the good seal performance of elastomeric material sealing ring, and sealing pair adjusts and is easy to, but service life is short.
The sealing pair of big-diameter ball valve can be hard-hard sealing pair with metal seal ring and metal seal ring composition, can also be that the soft-soft seal with elastomeric material sealing ring and elastomeric material sealing ring composition is secondary, it is also possible to be soft-hard sealing pair with elastomeric material sealing ring and metal seal ring composition.
In prior art, the list that the sealing pair of big-diameter ball valve is made up of a seal spool ring on spool and a valve seal ring on valve body seals big-diameter ball valve.This big-diameter ball valve is it cannot be guaranteed that big-diameter ball valve has sealing good seal performance, sealing pair adjustment is easy to, the feature of length in service life simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, propose the sealing good seal performance of a kind of sealing pair, sealing pair adjust be easy to, the double containment big-diameter ball valve of length in service life.
This utility model realizes with the following method.
Double containment big-diameter ball valve has valve body, there is water inlet the front end of valve body, there is outlet the rear end of valve body, valve shaft is had on valve body, in valve body one section of valve shaft is connected with hemispherical spool, sealing pair is had between hemispherical spool excircle and the inner periphery of valve body, sealing pair has the seal spool ring on the seal spool seat of spool excircle and the valve seal ring on the valve seal seat of valve body inner periphery, seal spool ring is the metal seal ring on seal spool seat, and valve seal ring is the metal seal ring on valve seal seat and elastomeric material sealing ring.
Sealing pair of the present utility model has the metal seal ring on seal spool seat, valve seal ring with matching is the metal seal ring on valve seal seat and two sealing rings of elastomeric material sealing ring, it it is a kind of double containment big-diameter ball valve, the service life of metal seal ring is long, the good seal performance of elastomeric material sealing ring, sealing pair adjusts and is easy to, the good combination property of sealing pair.
Below in conjunction with the accompanying drawings, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the perspective cross-sectional schematic diagram of a kind of double containment big-diameter ball valve proposed according to scheme of the invention of the present utility model；
Fig. 2 be Fig. 1 I at enlarged diagram.
Detailed description of the invention
Fig. 1, in Fig. 2, double containment big-diameter ball valve has valve body 1, there is water inlet 2 front end of valve body, there is outlet 3 rear end of valve body, valve shaft 4 is had on valve body, in valve body one section of valve shaft is connected with hemispherical spool 5, sealing pair is had between hemispherical spool excircle and the inner periphery of valve body, sealing pair has the seal spool ring on the seal spool seat of spool excircle and the valve seal ring on the valve seal seat of valve body inner periphery, seal spool ring is the metal seal ring 6 on seal spool seat, valve seal ring is the metal seal ring 7 on valve seal seat and elastomeric material sealing ring 8.
