Abstract
The invention discloses a manual regulating valve. The manual regulating valve comprises a valve body, a valve element, a rotating shaft and a control handle which is connected with the valve element and used for controlling the valve element through the rotating shaft. The rotating shaft penetrates through one edge of the valve body, a first semicircular sealing edge and a second semicircular sealing edge are arranged on the inner wall of the valve body, and the first sealing edge and the second sealing edge are not located on the same face. The first sealing edge is arranged on the upper half circle of the inner wall of the valve body, the second sealing edge is arranged on the lower half circle of the inner wall of the valve body, and the valve element is arranged between the first sealing edge and the second sealing edge. Rubber layers are arranged on the surfaces, facing the valve element, of the first sealing edge and the second sealing edge, semicircular triangle grooves are formed in the surfaces, facing the valve element, of the rubber layers, and semicircular triangle protrusions matched with the triangle grooves are arranged on the surfaces, corresponding to the triangle grooves in the first sealing edge and the second sealing edge, of the valve element. According to the manual regulating valve, the effective sealing effect can be achieved, deformation is not likely to happen, the structure is simple, operation is convenient, and the valve can be turned on and off only by rotating the control handle.
Description
Technical field
The present invention relates to a kind of valve, especially a kind of modulating valve of Non-follow control.
Background technique
Traditional modulating valve can cause certain wearing and tearing to part due to use, reduces the sealing between parts, so limited life cycle, and the leakage of gas or liquid easily occurs after wearing and tearing, and so both wasting resource has and there is potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, provide a kind of simple to operate and can effectively prevent from wearing and tearing cause reveal manual modulation valve.
The technical solution used in the present invention is: a kind of manual modulation valve, comprise valve body, spool, rotating shaft and the control handle by rotating shaft connection control spool, described rotating shaft runs through one side of valve body, it is characterized in that: the inwall of described valve body is provided with two semicircular first sealing strips and the second sealing strip, described first sealing strip and the second sealing strip are not on the same face, first sealing strip is arranged on the upper semi-circle of valve interior wall, second sealing strip is arranged in the lower semi-circle of valve interior wall, spool is located between the first sealing strip and the second sealing strip, described first sealing strip and the second sealing strip arrange rubber layer towards the face of spool, rubber layer arranges the triangular groove of semicircle on the face of spool, the face that spool is corresponding with triangular groove on the first sealing strip and the second sealing strip is provided with the triangular hill of the semicircle adapted with triangular groove.
Aforesaid a kind of manual modulation valve, is characterized in that: described triangular hill is quality of rubber materials.
Aforesaid a kind of manual modulation valve, is characterized in that: the thickness of described spool is identical with the distance between the first sealing strip and the second sealing strip.
Aforesaid a kind of manual modulation valve, is characterized in that: described spool is for circular.
Aforesaid a kind of manual modulation valve, is characterized in that: the diameter of described spool is identical with the inner diameter of valve body.
Aforesaid a kind of manual modulation valve, is characterized in that: the round outer side surface of described spool is provided with a circle rubber ring.
Aforesaid a kind of manual modulation valve, is characterized in that: described valve body is formed by stainless steel material die casting.
By technique scheme, the invention has the beneficial effects as follows: the present invention effectively can play the effect of sealing by the Placement of triangular groove and triangular hill, and the better tightness between rubber and rubber, not yielding, the rubber ring that the round outer side surface of spool is arranged can play two degree of sealings, and structure of the present invention is simple, easy to operate, only need rotate control handle just can switch valve.
