Abstract
The utility model discloses a sealing type lining ball valve. The sealing type lining ball valve comprises a valve body and a valve base; the top of the valve body is provided with a valve handle; the valve body and the valve handle are integrally arranged; a sealing base is arranged at a contact position of the valve body and the valve base; lining layers are arranged on the internal wall of the valve base and the external wall of the valve body; a spring hole is formed in the sealing base; an insertion hole which is matched with the spring hole is formed in the valve base; a spring is arranged inside the spring hole; one end of the spring is arranged inside the insertion hole; a sealing coating layer is arranged on the sealing base; the sealing coating layer is a tetrafluoroethylene-hexafluoropropylene copolymer layer. The sealing type lining ball valve has the advantages of being simple in structure and convenient to use; being good in sealing performance due to the facts that the sealing base and the valve base are connected through the spring and a layer of tetrafluoroethylene-hexafluoropropylene copolymer layer covers the external side of the sealing base; meanwhile enabling the service life of the integral ball valve to be prolonged to some extent and being good in practicability.
Description
Technical field
The utility model belongs to ball valve field, is specifically related to a kind of sealed type Lining Ball Valves.
Background technique
The ball valve of prior art is widely used in every field, different to the seal request of ball valve in different fields, especially in heavy chemical industry, large chemical fertilizer, petroleum and petrochemical fields, because the fluid of its conveying has corrosivity, therefore seal valve seat conventional in ball valve is as polytetrafluoroethylmaterial material structure, because elasticity is not enough, easily produces and leak, for big-diameter ball valve, its sealability does not reach requirement, and due to the frequent switch motion of ball valve meeting, also easily cause sealing configuration wearing and tearing, thereby affect the stability in use of ball valve.
Summary of the invention
The purpose of this utility model is to provide a kind of sealed type Lining Ball Valves of simple in structure, good seal performance.
The technological scheme that realizes the utility model object is a kind of sealed type Lining Ball Valves, comprise valve body and valve seat, the top of described valve body is provided with valve handle, described valve body and described valve handle are wholely set, contacting point at described valve body and valve seat is provided with sealing seat, described valve base inner wall and valve outer wall are equipped with backing layer, described sealing seat is provided with spring eye, described valve seat is provided with the jack matching with described spring eye, in described spring eye, be provided with spring, the other end of described spring is arranged in described jack, on described sealing seat, be provided with sealed packet coating, described sealed packet coating is perfluoroethylene-propylene layer.
Described sealing seat is the mixture of teflon and silicone rubber.
Described sealing seat is provided with stiffening rib, and described stiffening rib is arranged on the outside of described sealing seat.
Described stiffening rib is one.
The utlity model has positive effect: of the present utility model simple in structure, easy to use, sealing seat is connected by spring with valve seat, and at the coated one deck perfluoroethylene-propylene layer in the outside of sealing seat, its good seal performance, can extend the working life of whole ball valve to a certain extent, practicability is good simultaneously.
