Abstract
The utility model discloses a durable square head valve rod, including valve rod head and valve rod body, the valve rod head is the setting of hexagon structure, the valve rod body is circular structure setting and lies in the center of valve rod head, the valve rod head with valve rod body surface still is provided with alloy protecting cover shell, alloy protecting cover shell parcel set up in valve rod head and valve rod body surface, and the border of valve rod head is provided with the helicitic texture, alloy protecting cover shell with the helicitic texture of valve rod head corresponds fixed the setting. The utility model discloses an outside alloy protecting cover shell who sets up can effectual enhancement valve rod use intensity, simultaneously can effectual reduction loss, increase of service life.
Description
Technical field
This utility model is related to a kind of durable square toes valve rod.
Background technology
Valve rod is valve vitals, for being driven, above connects actuator or handle, and directly below band movable valve plug is moved
Or rotate, to realize valve switch or adjustment effect.Valve rod is one of key components and partss in valve, the thread segment of valve rod with
Valve sphere is connected.And valve rod is typically directly exposed to outside and is attached and uses, it is easy to be worn, causes service life
Greatly shorten, using effect is not good enough.
Utility model content
The purpose of this utility model is to provide a kind of alloy protective case by outside setting can effectively strengthen valve
The use intensity of bar, while loss can be effectively reduced, the durable square toes valve rod for increasing the service life.
The technical solution of the utility model is, a kind of durable square toes valve rod, including stem head and valve stem body, the valve
The hexagonal structure setting of head, the rounded structure setting of the valve stem body is simultaneously located at the center of the stem head, the valve
Head and the valve stem body outer surface are additionally provided with alloy protective case, and the alloy protective case parcel is arranged at the valve
Head and valve stem body outer surface, and the edge of the stem head is provided with helicitic texture, the alloy protective case and institute
The helicitic texture correspondence for stating stem head is fixedly installed.
In one preferred embodiment of this utility model, the inwall of the alloy protective case is at the valve stem body
Smooth planar structure.
In one preferred embodiment of this utility model, the end protrusion of the valve stem body is arranged at the alloy protective
Outside case.
In one preferred embodiment of this utility model, part of the valve stem body outside the alloy protective case
Surface is provided with fixed screw thread.
In one preferred embodiment of this utility model, the alloy protective case also passes through spiral shell with the stem head bottom
Bolt is fixedly connected.
The alloy protective case for passing through outside setting for a kind of durable square toes valve rod, this utility model described in the utility model
The use intensity of valve rod can effectively be strengthened, while loss can be effectively reduced, increased the service life.
Description of the drawings
Fig. 1 is the structural representation of this utility model durable square toes valve rod one preferred embodiment.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below, so that advantages and features energy of the present utility model
It is easier to be readily appreciated by one skilled in the art, apparent clearly defines so as to make to protection domain of the present utility model.
It is described in the utility model for a kind of durable square toes valve rod, as shown in figure 1, including stem head 1 and valve stem body 2,
The hexagonal structure setting of the stem head 1, the rounded structure setting of the valve stem body 2 is simultaneously located in the stem head
The heart, the stem head 1 and the outer surface of the valve stem body 2 are additionally provided with alloy protective case 3, and the alloy protective case 3 is wrapped
Wrap up in and be arranged at the stem head 1 and the outer surface of valve stem body 2, and the edge of the stem head 1 is provided with helicitic texture 4, institute
State that alloy protective case 3 is corresponding with the helicitic texture 4 of the stem head 1 to be fixedly installed.
The inwall of the alloy protective case 3 is smooth planar structure at the valve stem body 2.
The end protrusion of the valve stem body is arranged at outside the alloy protective case.
Part surface of the valve stem body 2 outside the alloy protective case 3 is provided with fixed screw thread 5.
The alloy protective case 3 is also fixedly connected with the bottom of the stem head 1 by bolt 6.
When using, directly alloy protective case can be fixed on valve rod by helicitic texture, and be fastened by bolts,
Alloy protective case can be changed after damaging, and then extend the service life of valve rod, can substantially reduce cost.
The alloy protective case for passing through outside setting for a kind of durable square toes valve rod, this utility model described in the utility model
The use intensity of valve rod can effectively be strengthened, while loss can be effectively reduced, increased the service life.
Specific embodiment of the present utility model is the foregoing is only, but protection domain of the present utility model is not limited to
This, any those of ordinary skill in the art, can be without creative work in the technical scope disclosed by this utility model
The change or replacement expected, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model
The protection domain that should be limited by claims is defined.
