Description

A hydraulic valve with throttling structure

Technical Field

The utility model relates to the technical field of hydraulic valves, in particular to a hydraulic valve with a throttling structure.

Background Art

A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the flow of oil, gas, and water pipeline systems in hydropower stations.

After the hydraulic valve is opened, the water inside the pipe 1 will flow normally. If the internal liquid flows too fast, it may cause waste. However, the existing water valve cannot control the flow speed of the liquid inside the pipe 1 after opening. In view of this, we need a hydraulic valve with a throttling structure.

A load-bearing spring, wherein the load-bearing spring is fixedly mounted inside the valve plate and is in a compressed state;

The baffle is fixedly mounted on the end of the bearing spring and penetrates through the interior of the valve plate.

Preferably, an extrusion rod passes through the interior of the valve plate, a return spring is sleeved on the outer wall of the extrusion rod, one end of the return spring is fixedly connected to the outer wall of the valve plate, and the other end of the return spring is fixedly connected to the outer wall of the extrusion rod.

Preferably, a push plate is fixedly mounted on the end of the extrusion rod, and a telescopic plate passes through the interior of the push plate.

Preferably, the inner thread of the push plate is connected to a threaded rod, and the end of the threaded rod is rotatably connected to the outer wall of the telescopic plate.

Preferably, a clamping block is fixedly mounted on the outer wall of the bent plate, and the bottom of the clamping block is arranged in an arc shape.

Compared with the prior art, the utility model provides a hydraulic valve with a throttling structure, which has the following beneficial effects:

1. The hydraulic valve with a throttling structure drives the extrusion rod to move to the right through the push plate in the throttling mechanism, and finally moves the bent plate out of the slot through the internal transmission, so that the baffle moves out of the valve plate, which can reduce the liquid flow inside the pipeline and prevent waste.

2. The hydraulic valve with a throttling structure can adjust the position of the telescopic plate by twisting the threaded rod. After the adjustment is completed, the extrusion rod can be pushed by making different liquid flow rates, so that the device can be throttled at different liquid flow rates.

DETAILED DESCRIPTION

As shown in Figures 1-3, the utility model provides a technical solution: a hydraulic valve with a throttling structure, including a pipeline 1, a support frame 2 is fixedly installed on the pipeline 1, a cylinder 3 is fixedly installed on the support frame 2, a valve plate 4 is fixedly installed at the end of the cylinder 3, and a throttling mechanism 5 is arranged inside the valve plate 4.

In this embodiment, a throttling mechanism 5 is provided inside the valve plate 4, and the extrusion rod 53 is driven to move to the right by the push plate 55 in the throttling mechanism 5, and finally the bent plate 59 is moved out of the slot 58 through the internal transmission, so that the baffle 52 is moved out of the valve plate 4, so that the liquid flow inside the pipeline 1 can be reduced to prevent waste. At the same time, the position of the telescopic plate 56 can be adjusted by screwing the threaded rod 57. After the adjustment is completed, the extrusion rod 53 can be pushed by different liquid flow rates, so that the device can be throttled at different liquid flow rates.

The throttling mechanism 5 includes a load-bearing spring 51, which is fixedly installed inside the valve plate 4. The load-bearing spring 51 is in a compressed state. A baffle 52 is fixedly installed on the end of the load-bearing spring 51. The movement of the baffle 52 out of the valve plate 4 can reduce the liquid flow inside the pipeline 1 to prevent waste. The baffle 52 passes through the inside of the valve plate 4. An extrusion rod 53 passes through the inside of the valve plate 4. A return spring 54 is sleeved on the outer wall of the extrusion rod 53. One end of the return spring 54 is fixedly connected to the outer wall of the valve plate 4, and the other end of the return spring 54 is fixedly connected to the outer wall of the extrusion rod 53. The elastic force of the return spring 54 makes the bent plate 59 clamped in the inside of the clamping groove 58, which is convenient for throttling again. A push plate 55 is installed, and the water flow pushes the push plate 55 to drive the extrusion rod 53 to move to the right. A telescopic plate 56 is penetrated inside the push plate 55, and a threaded rod 57 is connected to the internal thread of the push plate 55. The end of the threaded rod 57 is rotatably connected to the outer wall of the telescopic plate 56. The position of the telescopic plate 56 can be adjusted by twisting the threaded rod 57. A slot 58 is provided on the side wall of the baffle 52, and a bent plate 59 is fixedly installed on the outer wall of the extrusion rod 53. The extrusion rod 53 drives the bent plate 59 to move out of the slot 58 to release the limit. A clamping block 510 is fixedly installed on the outer wall of the bent plate 59. The bottom of the clamping block 510 is set to an arc shape. The baffle 52 squeezes the arc surface at the bottom of the clamping block 510, so that the clamping block 510 drives the bent plate 59 to move to the right to release the limit.

When working (or in use), after the cylinder 3 is started to drive the valve plate 4 to move upward and open, when the internal liquid flow rate is too fast, the push plate 55 will be pushed to drive the extrusion rod 53 to move rightward, and then the extrusion rod 53 drives the bent plate 59 to move out of the inner part of the card slot 58 to release the limit, and then the baffle 52 is moved downward by the elastic force of the bearing spring 51. By moving the baffle 52 out of the outside of the valve plate 4, the liquid flow inside the pipeline 1 can be reduced to prevent waste. At the same time, the position of the telescopic plate 56 can be adjusted by screwing the threaded rod 57. After the adjustment is completed, the extrusion rod 53 can be pushed by different liquid flow rates to complete the adjustment. When the valve plate 4 is closed, the baffle 52 on the inner wall of the pipeline 1 moves upward relative to the valve plate 4, and then the baffle 52 squeezes the arc surface at the bottom of the block 510, so that the block 510 drives the bent plate 59 to move rightward to release the limit, and finally the bent plate 59 is clamped in the inside of the card slot 58 by the elastic force of the reset spring 54, which is convenient for throttling again.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
