Description

All welded ball valve
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of all welded ball valve.
Background technology
Ball valve is a kind of common valve, and its structure has generally comprised valve body, valve gap, valve rod and spheroid, but existing valve body is all one-piece construction usually, therefore there is inconvenience during assembling. Meanwhile, also there is the poor defect of sealing property in existing ball valve.
Summary of the invention
For the deficiencies in the prior art, the utility model provides one and is convenient to install and the better all welded ball valve of sealing property.
For achieving the above object, the utility model provides a kind of all welded ball valve, include valve body, valve gap, valve rod and spheroid, described valve body is by left valve barrel, right valve barrel and middle valve body are formed, and described left valve barrel and right valve barrel are weldingly fixed on the left and right sides of middle valve body respectively, valve gap is weldingly fixed on middle valve body, valve rod is located in valve gap, and be connected with the spheroid being arranged in valve body, described spheroid is with left, seal valve seat it is equipped with between right valve barrel, described seal valve seat is the L-shaped structure with a transverse end and a longitudinal end, and connection angle between described transverse end and longitudinal end has offered a gap slot, the plastic seal ring abutting against sealing with spheroid and elastic seal ring it is equiped with in described gap slot, elastic seal ring correspondence is pressed on the top of plastic seal ring, longitudinal end of described seal valve seat has also been offered a medium admission passage, and the inner port of described medium admission passage extends on gap slot, corresponding on described elastic seal ring it is provided with expansion groove that medium admission passage inner port envelopes, the transverse end of described seal valve seat and a corresponding left side, O RunddichtringO it is equipped with between right valve barrel.
The beneficial effects of the utility model are: adopt said structure, can make to be formed between seal valve seat and spheroid double seal by the setting of plastic seal ring and elastic seal ring, medium enters in the expansion groove of elastic seal ring by medium admission passage simultaneously, elastic seal ring also can be made to expand further, thus improve the sealing property between seal valve seat and spheroid further, and can the abrasion of effective compensation trim, and then the sealing property making ball valve provided by the utility model is increased dramatically compared to existing technology.Separately, in the utility model, it is be welded and fixed with middle valve body by left valve barrel, right valve barrel due to described valve body, therefore monoblock type valve body compared to existing technology, spheroid and seal valve seat etc. are more easily installed in valve body by people, so that ball valve provided by the utility model also has advantage easy for installation concurrently.
It is twice that the utility model can be set to described O RunddichtringO further, the transverse end of described seal valve seat has offered a grease channel between twice O RunddichtringO, the inner port of described grease channel, towards spheroid, the external port of described grease channel is equiped with grease injection check valve. By the setting of grease channel, people can be made to be expelled on spheroid by grease, thus be convenient to spheroid and rotate, and greatly extend work-ing life.
The utility model also can be set between the transverse end of described seal valve seat and corresponding left and right valve body be also equipped with fire proof seal circle further. By setting up fire proof seal circle, ball valve provided by the utility model can be made also to have fp function concurrently.
The utility model also can be set on the longitudinal end of described seal valve seat to carry on the back to being also equipped with spring between the end face of spheroid and corresponding left and right valve body further. By arranging spring, can making between seal valve seat and spheroid the more tight of laminating, sealing property also will be better.
