Abstract
The utility model relates to a kind of ball valve square toes valve rod, comprise valve body and valve head, described valve head is fixed on valve body one end, and described valve head comprises cylindrical contiguous block and square toes, described square toes are fixedly connected with valve body by contiguous block, and the cross section that described square toes are vertical with valve axis direction is square.This ball valve square toes valve rod makes the connection of original spheroid into square toes and connects, and is reduced the shearing stress of contact position by enlarge active surface, realizes the function strengthening valve rod intensity, valve rod is not easily twisted off, increase the working life of valve rod.
Description
Technical field
The utility model relates to valve field, particularly a kind of ball valve square toes valve rod.
Background technique
Valve rod is the vitals on valve, for realizing the regulating action of valve.
The valve head of traditional ball-valve valve rod is all adopt key slot type valve rod, i.e. spheroid Placement, but the area of contact of this Placement is more limited, because pressure F draws shearing stress divided by the stressed active area S under circumference effect, so when pressure F remains unchanged, stressed active area S is larger, the shearing stress be subject to is less, and this Placement is because stressed active area S is less, so the shearing stress that the valve head of valve rod is subject to can be relatively large, valve rod is easily twisted off.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of stressed active area comparatively large, the ball valve square toes valve rod of valve rod long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of ball valve square toes valve rod, comprise valve body and valve head, described valve head is fixed on valve body one end, described valve head comprises cylindrical contiguous block and square toes, described square toes are fixedly connected with valve body by contiguous block, and the cross section that described square toes are vertical with valve axis direction is square.
Conveniently processing and fabricating, is connected to the circular cross-section of cylindrical contiguous block in described square toes.
In order to ensure the fastness of whole valve rod, described square toes, contiguous block and valve body are formed in one design.
Conveniently install, four angles of described square toes are arc angling.
The beneficial effects of the utility model are: this ball valve square toes valve rod makes the connection of original spheroid into square toes and connects, the shearing stress of contact position is reduced by enlarge active surface, realize the function strengthening valve rod intensity, valve rod is not easily twisted off, increase the working life of valve rod.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model ball valve square toes valve rod;
Fig. 2 is the right elevation of the utility model ball valve square toes valve rod;
In figure: 1. valve body, 2. contiguous block, 3. square toes.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of ball valve square toes valve rod, comprise valve body 1 and valve head, described valve head is fixed on valve body 1 one end, described valve head comprises cylindrical contiguous block 2 and square toes 3, described square toes 3 are fixedly connected with valve body 1 by contiguous block 2, and the cross section that described square toes 3 are vertical with valve body 1 axial direction is square.
Conveniently processing and fabricating, is connected to the circular cross-section of cylindrical contiguous block 2 in described square toes 3.
In order to ensure the fastness of whole valve rod, described square toes 3, contiguous block 2 and valve body are formed in one design.
Conveniently install, four angles of described square toes 3 are arc angling.
Compared with prior art, this ball valve square toes valve rod makes the connection of original spheroid into square toes 3 and connects, and is reduced the shearing stress of contact position by enlarge active surface, realizes the function strengthening valve rod intensity, valve rod is not easily twisted off, increase the working life of valve rod.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
