Abstract
The invention relates to the technical field of valve industries, in particular to a linkage device of a valve rod and a push rod. The linkage device comprises a linkage part and a pointer, and an inner hole of the linkage part is composed of a push rod hole formed in the right end and a valve rod hole formed in the left end. A pointer hole is formed in the side wall of the middle of the linkage part and matched with the pointer, and the pointer hole and the push rod hole are communicated with the valve rod hole formed in the left end. The pointer is composed of a thread section, a pointer section and a tapered section, the thread section is in threaded connection with the pointer hole, a flat end face with the 0.3mm length is arranged at the front end of the tapered section, and the taper angle of the tapered section is 55 degrees-65 degrees. When the linkage device is used, the linkage part and the pointer are combined into a whole, and meanwhile the structures of the linkage part and the pointer are simplified, so that manufacturing and machining cost is reduced, and beside a large amount of material is saved. The linkage device has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The present invention relates to valve industry technical field, particularly the coupling arrangement of a kind of valve rod and push rod.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.The equal more complicated of structure of the coupling of existing valve rod and push rod, processing cost is higher, is unfavorable for market competition; In addition, valve pointer or for thin iron plate is made, or be made for baroque cast iron, therefore pointer exists and is not durable or the shortcoming such as fabricating cost height.
Therefore be necessary the structure of existing valve part to carry out technological innovation further.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, valve rod reasonable in design, easy to use and the coupling arrangement of push rod.
For achieving the above object, the technical solution used in the present invention is:
The coupling arrangement of a kind of valve rod of the present invention and push rod, comprises coupling and pointer, and the endoporus of coupling is made up of with the valve rod hole that is positioned at left end the push-rod hole that is positioned at right-hand member respectively;
On the sidewall at coupling middle part, be provided with the pin hole matching mutually with pointer, pin hole, push-rod hole and the valve rod hole that is positioned at left end are connected and communicate;
Pointer is made up of thread section, pointer segment and taper section, and thread section is threaded mutually with pin hole; The front end of taper section is provided with the long planar end surface of 0.3mm, and the cone angle of taper section is 55～65 degree.
Further, it also comprises the nut matching mutually with thread section, and nut is fixedly installed on the outer side wall at the outer place of pin hole.
Further, described cone angle is 60 degree.
Further, the cross section of described coupling is outer-hexagonal shape.
Adopt after said structure, beneficial effect of the present invention is: the coupling arrangement of a kind of valve rod of the present invention and push rod, comprise coupling and pointer, and the endoporus of coupling is made up of with the valve rod hole that is positioned at left end the push-rod hole that is positioned at right-hand member respectively; On the sidewall at coupling middle part, be provided with the pin hole matching mutually with pointer, pin hole, push-rod hole and the valve rod hole that is positioned at left end are connected and communicate; Pointer is made up of thread section, pointer segment and taper section, and thread section is threaded mutually with pin hole; The front end of taper section is provided with the long planar end surface of 0.3mm, and the cone angle of taper section is 55～65 degree.In the time that use is of the present invention, by coupling and pointer two are combined into one, simplify the structure of coupling and pointer simultaneously, both reduce manufacture processing cost, also save a large amount of materials.The advantages such as the present invention has simple in structure, arranges rationally, and fabricating cost is low.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Figure 1-5, the coupling arrangement of a kind of valve rod of the present invention and push rod, comprises coupling 1 and pointer 2, and the endoporus of coupling 1 is made up of with the valve rod hole 1-2 that is positioned at left end the push-rod hole 1-1 that is positioned at right-hand member respectively;
On the sidewall at coupling 1 middle part, be provided with the pin hole 1-3 matching mutually with pointer 2, pin hole 1-3, push-rod hole 1-1 are connected and communicate with the valve rod hole 1-2 that is positioned at left end;
As a kind of optimal way of the present invention, it also comprises the nut 3 matching mutually with thread section 2-1, and nut 3 is fixedly installed on the outer side wall at the outer place of pin hole 1-3; Can strengthen like this being connected between pointer 2 and coupling 1.
As a kind of optimal way of the present invention, described cone angle is 60 degree.
As a kind of optimal way of the present invention, the cross section of described coupling 1 is outer-hexagonal shape, facilitates like this user's regular maintenance.
In the time that use is of the present invention, by coupling and pointer two are combined into one, simplify the structure of coupling and pointer simultaneously, both reduce manufacture processing cost, also save a large amount of materials.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
