Abstract

The utility model discloses a throttle valve clack, including sealing and throttle portion the sealing with throttle portion meets and is equipped with the clamping ring body on the terminal surface be equipped with in the throttle portion with clamping ring body matched with recess, the sealing still is equipped with plane sealing ring and toper sealing ring with the department of meeting of throttle portion. The utility model discloses a throttle valve clack increases clamping ring body back, and when closing the valve, during the recess in the throttle portion was clamp -oned to the clamping ring body, area of contact increased, and the leakproofness obtains improving, and later rethread plane sealing ring and toper sealing ring dicyclo are sealed, need not fix on the valve clack with screw or other modes, and installation practice is simpler, and the cost of valve clack processing is lower.

Description

A kind of throttling flap

Technical field

The utility model relates to field of mechanical technique, relates to a kind of throttling flap.

Background technique

Flap is the open and close of one of main parts size of valve, valve, and the change in location by flap realizes; In flap lifting process, the change of flow and the stroke direct proportionality of flap, be very suitable for the adjustment to flow; The structural design of flap, is directly connected to the usability of valve.

Conventional common throttling type valve clack, its flap is the solid metal body of shape of dripping, and not only volume is large, weight large, and consumptive material is many, manufacture cost is high, in the opening-closing process of valve, especially bring inconvenience; In addition throttle valve flap seal effect is undesirable at present, easily leaks when pipeline pressure is larger.

Model utility content

For the technical problem of above-mentioned existence, the purpose of this utility model is: propose a kind of throttling flap, structure is simple, easily manufactured, under the prerequisite not increasing cost of production, add the sealing area between flap and restriction, after valve closing, even if also excellent sealing can be realized when pipeline pressure is larger.

Technical solution of the present utility model is achieved in that a kind of throttling flap, comprises sealed department and restriction, described sealed department with described restriction phase contact surface is provided with press-ring body, described restriction is provided with the groove matched with described press-ring body; Described sealed department and restriction connecting part are also provided with plane sealing ring and cone-shaped sealing ring.

Improve further as the utility model, described restriction endoporus is trapezoidal hole.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:

Throttling flap of the present utility model, after increasing press-ring body, during throttle down, press-ring body is clamp-oned in the groove in restriction, and area of contact increases, and sealing is improved, afterwards again by plane sealing ring and the sealing of cone-shaped sealing ring dicyclo, do not need be fixed on flap by screw or other modes, install and implement more simply, and the cost of flap processing is lower.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of throttling flap of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described.

Be a kind of throttling flap as shown in Figure 1, comprise sealed department 1 and restriction 2, described sealed department 1 with described restriction 2 phase contact surface are provided with press-ring body 3, described restriction 2 is provided with the groove 4 matched with described press-ring body 3; Described sealed department 1 is also provided with plane sealing ring 5 and cone-shaped sealing ring 6 with restriction 2 connecting part; The endoporus of restriction 2 is trapezoidal hole, and trapezoidal structure ensures.

Throttling flap of the present utility model, after increasing press-ring body 3, during throttle down, press-ring body 3 is clamp-oned in the groove 4 in restriction 2, and area of contact increases, and sealing is improved, afterwards again by plane sealing ring 5 and the sealing of cone-shaped sealing ring 6 dicyclo, do not need be fixed on flap by screw or other modes, install and implement more simply, and the cost of flap processing is lower.

Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.

Claims

1. a throttling flap, comprises sealed department and restriction, it is characterized in that: on described sealed department with described restriction phase contact surface, be provided with press-ring body, described restriction is provided with the groove matched with described press-ring body; Described sealed department and restriction connecting part are also provided with plane sealing ring and cone-shaped sealing ring.

2. throttling flap according to claim 1, is characterized in that: described restriction endoporus is trapezoidal hole.
