Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of cutoff valve with high sealing performance.
Background technology
Stop valve is called pipe valve, and operation principle is to rely on valve stem pressure, valve clack sealing surface is closely pasted with sealing surface of seat
Close, so as to prevent flow of media, frictional force is small between sealing surface due to having during opening and closing for stop valve, relatively durable, opens high
Degree is little, the advantages of easy to manufacture, therefore very wide using scope.
Many stop valves all have that sealing is not high at present, and the problem of valve can still produce leakage after closing was using
Cheng Zhonghui causes various problems.
Utility model content
To solve the above problems, the utility model discloses a kind of cutoff valve with high sealing performance, structure is novel, valve seat and flap
Between sealing it is higher, service life is longer.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of cutoff valve with high sealing performance, including valve body, bonnet, valve rod and flap, the bonnet is fixed by bolt one to be connected
It is connected on valve body, the valve rod is arranged in bonnet, and enters through bonnet in valve body, valve seat is provided with the valve body, it is described
Valve seat is located at the lower section of valve rod, it is characterised in that：The flap includes upper flap and lower Disc, and the upper flap is cylinder
Shape, the upper flap is fixedly connected by bolt two with valve rod, the lower Disc include a cylinder and an inverted round stage, it is described fall
Round platform is fixedly installed on the middle part of cylinder lower surface, and the cylinder lower end is provided with the groove of hollow cylinder shape, the valve
Seat is bell mouth shape, and can be fitted completely with the inverted round stage of lower Disc, and the projection of hollow cylinder shape is provided with the valve seat,
The projection can be fitted completely with groove.
As a kind of improvement of the present utility model, the diameter of the contact surface of the inverted round stage and cylinder is less than cylinder
Diameter.
As a kind of improvement of the present utility model, the diameter of the hollow cylinder shape groove is more than inverted round stage and cylinder
Contact surface diameter, the diameter of the hollow cylinder shape groove is less than the diameter of cylinder.
As it is of the present utility model it is a kind of improve, the side of the inverted round stage, the top of groove, lower Disc lower surface it is equal
It is provided with elastic packing packing ring.
As a kind of improvement of the present utility model, the valve rod upper end is fixedly connected with handwheel.
The beneficial effects of the utility model：
The utility model is simple in construction, inverted round stage corresponding with seat shape is provided with below flap, when valve is closed
Flap can be fitted tightly between valve seat, strengthen the sealing of valve；Have on valve seat under the projection of hollow cylindrical shape, flap
End is provided with the groove being engaged with projection, and flap is engaged with valve seat when valve is closed, and further increases the sealing of valve
Property, meanwhile, projection can also play blocking effect when a small amount of leakage is occurring in valve, prevent leak liquid from flowing into liquid outlet；
Flap lower end is provided with three groups of elastic packing packing rings, makes the sealing of valve higher.
