Abstract
The utility model provides a kind of Quick connected ball valve, comprise valve body, sealing gasket, valve ball, valve gap, valve rod, seal ring, clamping cap, handle and set screw nut, ball valve two ends are in the feed-water end of straight-tube shape and waterexit end, are provided with the fast connected components of pipeline in described feed-water end and waterexit end inner chamber.The utility model can the pipeline valve accessory such as connecting copper pipe, steel pipe, PEX pipe, Polybutylene Pipe fast, reusable, solves existing ball valve and is connected more loaded down with trivial details problem with pipeline.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of ball valve, particularly relates to a kind of Quick connected ball valve that can be easy to connect with pipeline.
Background technique
In China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.It has the action of 90-degree rotation, and faucet body is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline, and it is tight that it only needs to use the operation of 90-degree rotation and very little moment of rotation just can close.
Ball valve needs in use to join and uses with pipeline.The ball valve sold on the market has internal thread inside general two ends, pipeline have the outside thread that mates with it and be threaded with ball valve, but consider the sealing be connected between pipeline with ball valve, common way covers one deck waterproof membrane on the threaded end of pipeline, again pipeline spiral shell is linked in ball valve, operate more loaded down with trivial details.
Model utility content
The purpose of this utility model is the problems referred to above existed for prior art, proposes a kind of Quick connected ball valve easy to connect with pipeline.
The purpose of this utility model realizes by following technical proposal: a kind of Quick connected ball valve, comprise valve body, sealing gasket, valve ball, valve gap, valve rod, seal ring, clamping cap, handle and set screw nut, wherein the axially open of valve body connects valve gap, ball valve core is arranged in the cavity that valve body and valve gap formed, valve rod is arranged in the top tubular cavity of valve body, the two ends of valve rod connect spherical spool and handle respectively, valve rod and handle are fixed by set screw nut, sealed by clamping cap press seal circle between described valve rod and valve body, sealed by O RunddichtringO between described valve rod and clamping cap, it is characterized in that, described ball valve two ends are in the feed-water end of straight-tube shape and waterexit end, the fast connected components of pipeline is provided with in described feed-water end and waterexit end inner chamber.
As improvement, the fast connected components of described pipeline comprises O type circle, retaining lining, resilience gear ring, steel wire collar, pine move back lining, fixed cover.
As improvement, described O type circle, retaining lining and resilience gear ring are successively placed in the cavity of ball valve two ends, and described retaining lining is the loop configuration of conical internal cavity; The large end of described retaining lining is against described O type circle, and described retaining lining small end and conical internal cavity support described resilience gear ring, are fixed described resilience gear ring with steel wire collar.
As improvement, it is that one end has and the described conic-insertion-piece that resilience gear ring teeth coordinate, external diameter progressively reduces that described pine moves back lining.
As improvement, described fixed cover inner chamber has and blocks the step that described pine moves back lining, corresponding, described pine moves back flange lining outer side wall having and matches with described fixed cover inner chamber step.
Compared with prior art, the utility model has the advantage of: the utility model is provided with the fast connected components of pipeline at feed-water end and waterexit end, during use, pipeline one end is inserted in the fast connected components of pipeline, under the effect of hydrodynamic pressure, make the stressed generation deformation of seal ring and pipeline the inner is compressed, can prevent flowing medium from leaking into external environment condition simultaneously.The utility model can the pipeline valve accessory such as connecting copper pipe, steel pipe, PEX pipe, Polybutylene Pipe fast, reusable; The utility model has the features such as corrosion-resistant, high temperature resistant, high pressure resistant, compression resistant, sealing is lasting, long service life, friction factor are low, is applicable to the medium circulation tube roads such as highly basic, strong acid, chemical industry and oil refining pipeline.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
