Description

Multi-way valve stem linkage control device

technical field

The utility model relates to a hydraulic multi-way valve component, in particular to a hydraulic multi-way valve stem linkage control device which needs to provide support for two actuators to complete compound actions on engineering machinery.

Background technique

Existing conventional hydraulic multi-way valves are mostly controlled manually, and different actuators are controlled by moving the handle by hand according to the number of working joints. If the actuators act in sequence, the control can be completed with one hand operation; if the two actuators need compound actions to improve the efficiency of on-site operations, two hands are required to operate the two handles at the same time. Relatively small, two hands hold the adjacent operating handle to control the multi-way valve at the same time, which is inconvenient to operate and prone to fatigue, resulting in a decrease in operating accuracy and efficiency, and is more prone to accidents and equipment damage.

Utility model content

The purpose of the utility model is to provide a multi-way valve stem linkage control device.

The purpose of this utility model is achieved through the following ways: a multi-way valve stem linkage control device, one end of the cross universal joint is connected with the fixed seat, the other end is connected with the linkage plate, the linkage plate is equipped with a control handle, and the linkage plate There is a through hole on each side, and a connecting rod ball joint is installed on each of the two through holes. A threaded connecting rod is installed on the connecting rod ball joint, and a universal joint fork is installed at the end of the threaded connecting rod, and the universal joint fork moves through the cotter pin. A valve stem is installed.

As a further optimization of this solution, an apron is installed between the connecting rod ball joint and the linkage plate.

The multi-way valve stem linkage control device of the utility model is used for the purpose of controlling two valves with only one handle through the linkage device. It makes the operation of the multi-way valve easier, improves efficiency, reduces fatigue, and reduces accidents to a certain extent.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is a structural representation of the utility model;

In the figure, cross universal joint 1, fixed seat 2, linkage plate 3, control handle 4, connecting rod ball joint 5, connecting rod ball joint 5, threaded connecting rod 6, universal joint fork 7, cotter pin 8, valve stem 9. Apron 10.

Detailed ways

As shown in Figure 1, in the multi-way valve stem linkage control device of the present invention, one end of the cross universal joint 1 is connected with the fixed seat 2, and the other end is connected with the linkage plate 3, and the linkage plate 3 is equipped with a control handle 4, and the linkage plate 3. A through hole is arranged on both sides, and a connecting rod ball joint 5 is installed on each of the two through holes. A rubber ring 10 is installed between the connecting rod ball joint 5 and the linkage plate 2 to reduce wear. A threaded connecting rod 6 is housed on the connecting rod ball joint 5, and a universal joint fork 7 is installed at the end of the threaded connecting rod 6, and the universal joint fork 7 is movably installed with a valve stem 9 through a cotter pin 8, so that there is a gap between the connecting rod and the valve stem. Angular displacement can be produced.

The cross universal joint 1 can make the linkage plate 3 rotate in any direction, and the connecting rod ball joint 5 is welded by a bolt with a ball head and a holder with a groove by a special method, which can make the linkage plate 3 and Angular displacement can be generated between the threaded connecting rods 6, so as to better control the multi-way valve.

In Fig. 1, viewed from the cross universal joint 1 as the endpoint, the arrangement directions of the two connecting rod ball joints 5 differ by 90 degrees. 6 can move in the vertical direction, and pushing and pulling one valve stem 9 can realize the control to another valve stem 9 alone; Moving in the vertical direction, pushing and pulling the valve rod 9 can realize the control of the first valve rod 9 alone, so as to achieve the purpose of one rod controlling two valves.

And when handle 1 is moved back and forth, two threaded connecting rods 6 can move on vertical direction, push and pull two valve rods 9, then can control two valve rods 9 simultaneously, reach the purpose of simultaneously controlling.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the art can think of it without creative work within the technical scope disclosed in the utility model. All changes or replacements should fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
