Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of machinery valve.
Background technique
Machinery valve is widely used on the engineering machinery engine such as loader, road roller outlet pipe, and operationally, machinery valve is by the folding of continuous rotation screw rod control valve, and folding Directivity is poor, the wayward observation of folding size for existing above-mentioned machinery; The inside of machinery valve adopts black rubber pad to seal, and easily aging, physical life is short; But also often there is feedback antifreeze liquid leakage accident.
As shown in Figure 1-2, existing valve is made up of four standard piece, i.e. pagoda joint 11, ball valve 12, tapered thread joint 13 and elbow bend 14, the two ends, left and right of ball valve 12 are connected with capitate inipple 13 one end with leg elbow 14 respectively, and the other end of leg elbow 14 is connected with pagoda joint 13, and 13 above-mentioned joints all need to do water-proofing treating, but existing water-proofing treating all can not accomplish sealing, often occur the generation of water leakage phenomenon, and processing cost is high, consumption material.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of machinery of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of structure operation simple, folding and folding size very clear; Long service life, the machinery valve of the antifreeze liquid leakage accident that thorough solution causes because of valve.
Machinery valve of the present invention, comprises valve body, bonnet, ball valve and valve rod, and described bonnet is arranged on one end of valve body, one end of valve body is provided with valve seat near valve place, be provided with ball valve in valve seat, the top of ball valve is connected with valve rod, and the top of valve rod is connected with handle.
Further, the bottom of described valve rod is stretched in valve body, and is connected with described ball valve, and one end that valve rod stretches in valve body is provided with annular groove, is provided with O type circle, to seal between valve rod and valve body in annular groove.
Further, the top of described valve rod is connected with handle by hexagonal flange screw.
Further, be threaded between described bonnet and one end of valve body.
Further, described valve body is L-type, and the minor face of this L-type and handle are positioned at homonymy or the both sides on the limit, field of L-type.
Further, described valve seat adopts PTFE to make.
Further, described valve body is one of the forming structure.
By such scheme, the present invention at least has the following advantages: ball valve synchronous rotary (angle is identical) during handle with sleeve; Along with the rotation of ball valve and valve seat form angle, angle gets over flood (or antifreeze liquid) otherwise the less fluid flow of the less angle of flow is larger.When the opening surface of ball valve and valve seat opening surface angle are 0 degree, valve body is that full open position flow is maximum; When the opening surface of ball valve 4 and valve seat 5 opening surface angle are 90 degree, valve body is complete closed state flow is 0; Structure operation is simple, folding and folding size very clear; Long service life, thoroughly solves the antifreeze liquid leakage accident because valve causes.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
