Abstract
The utility model discloses a high pressure resistant anticorrosive fast valve, including valve body, valve gap, valve clack, valve rod, disk seat, compression spring I and operating device, valve gap fixed connection is on valve body upper portion, the valve rod vertical stroke is put, is installed in the valve gap, and the lower extreme is connected with the valve clack in the cavity of middle part in stretching into valve body middle part cavity, the disk seat sets up in the valve clack lower part, and fixed connection in the cavity, is equipped with on valve clack, the disk seat and seals the sealed face of complex in the middle part of the valve body, compression spring I sets up under valve clack and valve gap between the terminal surface, the spherical sealed face of sealed face for mutually combining between valve clack, the disk seat, the further improvement lies in: the valve clack floats and connects at the valve rod lower extreme, valve body fluid passage inner wall is equipped with corrosion -resistant layer. The utility model discloses it is high pressure resistant, corrosion -resistant, reliably durable, long service life.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of fast valve.
Background technique
At present, known fast valve be generally on common valve, install pneumatic or hydraulic pressure additional, motor-operating mechanism forms, its structure often comprises valve body, valve gap, flap, valve rod and is located at several parts such as operating device on valve gap support.In the fast valve of prior art, between flap, valve seat, sealing surface is plane, this sealing configuration manufacture is simple, but is subject to the restriction of accuracy of manufacturing, and the sealing surface between flap, valve seat cannot realize combining closely, make the fast valve poor sealing of prior art, resistance toly to force down.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of and the sealing surface between flap, valve seat can be made to combine closely, significantly improve the high voltage resistant corrosion fast valve of sealing reliability and withstand voltage properties.
The utility model is achieved through the following technical solutions technical goal.
High voltage resistant corrosion fast valve, comprises valve body, valve gap, flap, valve rod, valve seat, Compress Spring I and operating device; Described valve gap is fixedly connected on valve body top; Described valve rod is perpendicular to be put, be arranged in valve gap, and lower end is stretched in valve body central cavity, is connected with the flap in central cavity; Described valve seat is arranged on flap bottom, and be fixedly connected in valve body central cavity, flap, valve seat are provided with the sealing surface that can be sealed and matched; Described Compress Spring I is arranged between flap and valve gap lower end surface; Its improvements are: between described flap, valve seat, sealing surface is the spherical seal surface that can be combined with each other.
In said structure, described flap floating connection is in valve rod lower end.
In said structure, described valve body liquid passage interior wall is provided with anti-corrosion layer.
In said structure, described anti-corrosion layer is polytetrafluoroethylene floor.
The utility model compared with prior art, has following good effect:
1, between flap, valve seat, sealing surface is the spherical seal surface that can be combined with each other, and is sealed between flap, valve seat by spherical seal surface, the sealing surface between flap, valve seat can be made to combine closely, significantly improve sealing reliability and withstand voltage properties.
2, flap floating connection is in valve rod lower end, can increase the flexibility of flap, and the sealing surface between flap, valve seat can be made more to combine closely, and improves sealing reliability and withstand voltage properties further.
3, valve body liquid passage interior wall is provided with anti-corrosion layer, can significantly strengthen decay resistance of the present utility model.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
