Description
Technical field
The utility model relates to a kind of ball valve, specifically is to compensate the metallic seal floating ball valve automatically.
Background technique
Existing metallic seal floating ball valve, in switching process repeatedly, the sealing surface between spheroid and the valve seat can be worn; So; Pretightening force between spheroid and the valve seat will constantly reduce, and along with the increase of switch number of times, it is more and more serious to wear and tear; Finally cause spheroid and sealing surface of seat to form the gap and can not accomplish the function of sealing, this just makes shorten the working life of ball valve.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, provides a kind of and can compensate the wearing and tearing between spheroid and the valve seat automatically, thereby avoided in seal process, occurring between the spheroid and valve seat the automatic compensation metallic seal floating ball valve in gap.
The purpose of the utility model mainly realizes through following technological scheme: compensate the metallic seal floating ball valve automatically; Comprise left body, valve body, spheroid and valve rod; Said left body is connected with valve body and constitutes the spheroid chamber with valve body, and left body is provided with the medium import of connecting the spheroid chamber, and valve body is provided with the media outlet of connecting the spheroid chamber; Said spheroid is arranged in the spheroid chamber, and said valve rod one end passes valve body and is connected with spheroid; Be provided with the entrance point valve seat that is tightly connected with left body between said medium import and the spheroid chamber; Left side body and entrance point valve seat constitute cavity; Be provided with the counterbalance spring that two ends act on left body and entrance point valve seat respectively in this cavity; Be provided with the outlet end valve seat that is connected with valve seal between said media outlet and the spheroid chamber, said spheroid contacts with the outlet end valve seat with the entrance point valve seat.
Static seal is connected with the sealing adjusting element between said entrance point valve seat and the left body.
The material of said sealing adjusting element is Expanded graphite or reinforced TFE.
Static seal is connected with gasket seal between said outlet end valve seat and the valve body.
The material of said gasket seal is Expanded graphite or reinforced TFE.Expanded graphite and reinforced TFE all can satisfy the usage requirement of low temperature, high temperature, have Applicable scope widely, and therefore, the utility model sealing adjusting element and gasket seal preferably adopt Expanded graphite or reinforced TFE to process.
Said spheroid, entrance point valve seat and outlet end valve seat three process by metallic material, and the three surface all is coated with hard alloy layer.Cemented carbide has high tenacity and high wear resistance, and so, the spheroid of the utility model, entrance point valve seat and outlet end valve seat can be applicable to abominable work condition environment.
Said counterbalance spring is that nickel-base alloy is processed.Because of nickel-base alloy has excellent elasticity performance and elastic stiffness, and have corrosion-resistant strong characteristic, counterbalance spring adopts this kind material to process, and can prolong the working life of the utility model.
Compared with prior art; The utlity model has following beneficial effect: the utility model is provided with the counterbalance spring that two ends act on left body and entrance point valve seat respectively; Counterbalance spring can act on the entrance point valve seat and make the entrance point valve seat fit tightly spheroid; So, the utility model can be avoided in seal process, the gap occurring between the spheroid and valve seat.
