Abstract
The utility model discloses a main valve guide sleeve for a hydraulic valve. A step-shaped outer edge is arranged at the lower end of a sleeve body, a plurality of through holes are formed on the outer wall in the middle of the sleeve body, an annular groove is arranged on the outer wall of the upper end of the sleeve body, a chamfer is arranged at the outer edge of the top of the sleeve body, the sleeve body is of a cylinder and is not provided with covers at the upper part and the lower part. According to the main valve guide sleeve for the hydraulic valve, the step-shaped outer edge is arranged outside the sleeve body, a groove structure is arranged on the outer wall of the sleeve body, so that the sleeve body and a main valve are combined closely and can also be firmly clamped after being used for a long time, and the through holes formed on the outer wall can be used for a fluid in the valve to flow through.
Description
Technical field:
The utility model relates to the hydrovalve part field, relates in particular to a kind of hydrovalve main valve guide pin bushing.
Background technique:
Hydrovalve is a kind of Automation Elements with the pressure oil operation, and it is subjected to the control of voltage distribution valve pressure oil, and common and electromagnetic distributing valve is used in combination, and can be used for the break-make of distant control water power plant oil, gas, water piping system; It is the element that is used for controlling Ye Ti Ya Li ﹑ flow and direction in the hydraulic transmission, wherein pilot pressure be called pressure valve processed, the control flow be called flow control valve, Kong Tong ﹑ processed disconnected and flow to be called position control valve.
The main valve guide pin bushing that hydrovalve in the past uses mostly is columnar structured, with the frictionally that cooperates between main valve and the miscellaneous part, therefore wearing and tearing may occur after long-term the use and cause rocking; Therefore imagination provides a kind of new structure to solve this problem.
The model utility content:
The purpose of this utility model just provides a kind of hydrovalve main valve guide pin bushing, solve the main valve guide pin bushing that hydrovalve in the past uses, mostly be columnar structured, with the frictionally that cooperates between main valve and the miscellaneous part, therefore wearing and tearing may occur after long-term the use and cause the problem of rocking.
The technical solution adopted in the utility model is:
A kind of hydrovalve main valve guide pin bushing: the body lower end has step-like outer edge, has some through holes on the outer wall of body middle part, has annular groove on the outer wall of body upper end, and body top outer edge has chamfering.
Described body is cylindrical body, up and down uncovered.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by arranging step-like outer edge outside body, and opens reeded structure at outer wall, and body is combined with main valve closely, and long-term use also can keep engaging firmly, and having simultaneously through hole on the outer wall can pass through for the valve inner fluid.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
A kind of hydrovalve main valve guide pin bushing: body 1 lower end has step-like outer edge 2, has some through holes 3 on the body 1 middle part outer wall, has annular groove 4 on the body 1 upper end outer wall, and body 1 top outer edge has chamfering 5; Body 1 is cylindrical body, up and down uncovered.
Above-described embodiment only is better mode of execution of the present utility model, and in addition, the utility model can also have other implementations.Need to prove, under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
