Description
Technical field
The utility model is related to a kind of anti-pushing-out structure of valve rod.
Background technology
The existing anti-pushing-out structure of valve rod, can typically be used using pin thrust or directly using executing agency come thrust
, it is necessary to open up the mounting hole for installing spacer pin on valve rod during pin thrust, so inherently weaken the intensity of valve rod, make
Valve rod is easily broken from the position of spacer pin during, and the strong of valve rod is now only improved by increasing stem diameter
Degree, but the diameter of increase valve rod inherently improves the manufacturing cost of corresponding valve；During using executing agency's thrust, due to valve
What bar was connected together with executing agency, in executing agency, disassembly process valve stem part must be dismounted simultaneously, so easily right
The internal structure of valve is impacted, and also add the difficulty of maintenance of valve.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art that there is provided a kind of anti-pushing-out structure of valve rod.
The utility model is achieved in that a kind of anti-pushing-out structure of valve rod, including a valve body and a valve rod, the valve body
Upper end offer the blind hole of opening upwards setting, the bottom surface of the blind hole offer one with the blind hole be coaxially disposed it is logical
A jump ring is connected with hole, the inwall of the blind hole；The lower removable of the valve rod is arranged in the through hole, the valve rod
A thrust ring is installed with periphery wall, the thrust ring is located between the bottom surface of the blind hole and the jump ring.
Further, a split annulus, top surface and the jump ring of the split annulus are provided with below the jump ring
Bottom surface abut, the bottom surface of the split annulus abuts with the top surface of the thrust ring, the bottom surface of the thrust ring with it is described blind
The bottom surface in hole is abutted.
Further, the inwall of the blind hole offers a jump-ring slot, and the jump ring is arranged on the jump-ring slot.
Further, a neck is provided with the valve rod, the thrust ring is arranged on the neck.
Specifically, the valve rod is integrally formed with the thrust ring.
The anti-pushing-out structure of valve rod that the utility model is provided, when valve rod is rotated, the thrust ring on valve rod is in the bottom surface of blind hole
And can not be moved up and down under the restriction effect of jump ring, the situation that valve rod is moved up and down so is avoided, thrust ring is arranged on
It is on the periphery wall of valve rod, little to the intensity effect of valve rod, it is to avoid the phenomenon that valve rod is broken, the diameter of such valve rod is just
Need not additionally it increase, so as to reduce the manufacturing cost of corresponding valve；In addition, split annulus is arranged on thrust ring and jump ring
Between, it can directly be changed after split annulus abrasion, so facilitate the service life for improving whole valve；Meanwhile, split circle
Ring is also avoided that thrust ring directly occurs friction with jump ring surface and causes that jump ring can not take out after being worn and jump ring is to thrust
The phenomenon that the position-limiting action of ring dies down and makes valve rod be scurried out by jump ring side.
Brief description of the drawings
In order to illustrate more clearly of the technical solution of the utility model, below by the required accompanying drawing used in embodiment
It is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other attached
Figure.
Fig. 1 is the schematic diagram that the utility model provides the anti-pushing-out structure of valve rod that embodiment is provided.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
As shown in figure 1, the anti-pushing-out structure of a kind of valve rod that the utility model embodiment is provided, including a valve body 1 and a valve
Bar 2, the upper end of valve body 1 offers the blind hole 11 of opening upwards setting, and it is coaxial with blind hole 11 that the bottom surface of blind hole 11 offers one
A jump ring 13 is connected with the through hole 12 of setting, the inwall of blind hole 11；The lower removable of valve rod 2 is arranged in through hole 12, valve rod 2
Periphery wall on be installed with a thrust ring 21, thrust ring 21 is located between the bottom surface of blind hole 11 and jump ring 13.
Further, the lower section of jump ring 13 is provided with a split annulus 14, the top surface of split annulus 14 and the bottom of jump ring 13
Face is abutted, and the bottom surface of split annulus 14 is abutted with the top surface of thrust ring 21, and the bottom surface of thrust ring 21 is abutted with the bottom surface of blind hole 11.
Further, the inwall of the blind hole 11 offers a jump-ring slot 15, and jump ring 13 is arranged on jump-ring slot 15.
Further, a neck 22 is provided with the valve rod 2, thrust ring 21 is arranged on neck 22.
Specifically, the valve rod 2 is integrally formed with thrust ring 21.
The anti-pushing-out structure of valve rod that the utility model is provided, when valve rod 2 is rotated, the thrust ring 21 on valve rod 2 is in blind hole 11
Bottom surface and jump ring 13 restriction effect under can not move up and down, so avoid the situation that valve rod 2 is moved up and down, thrust
Ring 21 is arranged on the periphery wall of valve rod 2, little to the intensity effect of valve rod 2, it is to avoid the phenomenon that valve rod 2 is broken, this
The diameter of sample valve rod 2 avoids the need for extra increasing, so as to reduce the manufacturing cost of corresponding valve；In addition, split annulus 14
It is arranged between thrust ring 21 and jump ring 13, split annulus 14 can be changed directly after wearing and tearing, so facilitates the whole valve of raising
The service life of door；Meanwhile, split annulus 14 is also avoided that thrust ring 21 directly occurs friction with the surface of jump ring 13 and causes jump ring
13 be worn after can not take out and jump ring 13 dies down to the position-limiting action of thrust ring 21 and valve rod 2 is scurried out by the side of jump ring 13
Phenomenon.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and moistened
Decorations are also considered as protection domain of the present utility model.
