Abstract
The utility model discloses an optimized structure of a contact point of a stop valve rod and a valve clack, which comprises a valve rod, a gasket and a valve clack assembly, wherein the valve rod is movably arranged in the valve clack assembly, the gasket is embedded and arranged at the bottom end in the valve clack assembly, and the gasket is in sliding fit with the bottom end of the valve rod. The utility model adopts a new structure, improves the joint of the valve rod and the valve clack of the stop valve, and arranges the gasket at the joint of the valve rod and the valve clack assembly, thereby effectively avoiding the valve clack from being abraded to influence the strength of the valve clack.
Description
Technical Field
The utility model relates to a stop valve, in particular to an optimized structure of a contact point of a valve rod and a valve clack of the stop valve.
Background
The shut-off valve is a valve with a closing member (valve clack) moving along the central line of a valve seat, and mainly has the functions of adjustment and cutting-off in a pipeline. The stop valve adopts a structure that a valve rod rotates to move up and down, particularly in the closing process, the closing force is large, and the valve rod is generally harder than a valve clack material, so that the head of the valve rod and a valve clack medium area are frequently abraded, and the strength of the valve clack is influenced after long-time use.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an optimized structure of a contact point of a valve rod and a valve clack of a stop valve, and solving the problem that the valve rod head and a valve clack medium area of the existing stop valve are frequently abraded, and the strength of the valve clack is influenced after the stop valve is used for a long time.
In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a stop valve rod and valve clack contact point optimal structure, includes valve rod, gasket and valve clack subassembly, valve rod movable mounting is in the valve clack subassembly, the gasket is installed in the inside bottom embedding of valve clack subassembly, gasket and valve rod bottom sliding fit.
On the basis of the scheme, the valve rod is in sliding fit with the valve clack assembly.
On the basis of the scheme, the hardness of the gasket is greater than that of the valve rod.
Compared with the prior art, the utility model has the beneficial effects that: the utility model relates to an optimized structure of a contact point of a valve rod and a valve clack of a stop valve, which adopts a new structure, improves the joint of the valve rod and the valve clack of the stop valve, and arranges a gasket at the joint of the valve rod and the valve clack assembly, thereby effectively avoiding the valve clack from being abraded to influence the strength of the valve clack.
Drawings
FIG. 1 is a schematic view of a partial structure of an optimized structure of a contact point of a valve rod and a valve clack of a stop valve in a valve body.
The reference numbers in the figures are: 1-valve rod, 2-gasket, 3-valve clack assembly.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
Referring to fig. 1, the optimized structure of the contact point of the valve rod and the valve clack of the stop valve comprises a valve rod 1, a gasket 2 and a valve clack assembly 3, wherein the valve rod 1 is movably installed in the valve clack assembly 3, the gasket 2 is embedded into the bottom end of the valve clack assembly 3, the gasket 2 is in sliding fit with the bottom end of the valve rod 1, and the gasket 2 can effectively avoid abrasion of the valve rod 1 to the valve clack assembly 3 when the valve rod 1 rotates.
The valve rod 1 is in sliding fit with the valve clack component 3, so that the valve rod 1 can rotate in the valve clack component 3 conveniently; the hardness of the gasket 2 is greater than that of the valve rod 1, so that the valve rod 1 can be effectively prevented from wearing the valve clack component 3 when rotating.
The principle and the advantages of the utility model are as follows: the utility model provides a stop valve rod and valve clack contact point optimization structure, which adopts a new structure, wherein a gasket 2 with higher hardness than that of a valve rod 1 is arranged at the bottom end inside a valve clack assembly 3, so that the valve clack can be effectively prevented from being abraded by the valve rod 1, the strength of the valve clack is influenced, and the service performance of the valve is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
