A hydraulic pipe valve with convenient maintenance

Abstract

This utility model discloses a hydraulic pipe valve that is easy to maintain, specifically relating to the field of valve technology. The valve includes a valve with connecting pipes at both its inlet and outlet, and a parallel pipe fixedly connected between the two connecting pipes. Each connecting pipe has a first closing chamber, and a first baffle is slidably connected inside the first closing chamber. In practical operation, when the valve is disassembled from the two connecting pipes, the second baffle moves, preventing it from blocking the second closing chamber. When the trigger plate resets with the connecting plate, the ball bearings roll into contact with the side of the trigger plate, pushing the drive head and the first movable rod to move. This causes the first baffle to block the first closing chamber, allowing the medium entering the connecting pipe to enter the parallel pipe. This facilitates valve maintenance, and the flow of the medium does not need to be interrupted during valve disassembly and maintenance, effectively avoiding production efficiency losses due to downtime.

Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a hydraulic pipe valve that is easy to maintain. Background Technology

[0002] Hydraulic pipe valves are a type of high-pressure ball valve. They are valves installed on hydraulic pipes to regulate the opening and closing of hydraulic pipes. High-pressure ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. They have strong shearing force. This type of valve should generally be installed horizontally in the pipeline.

[0003] A search revealed, for example, a utility model with publication number CN213629008U, which discloses a hydraulic pipe valve that is easy to maintain. The valve includes an overall valve structure comprising a valve base and a valve cover. Both ends of the valve base and valve cover are secured with valve retaining rings, and the valve base and valve cover are connected and fixed via these retaining rings. This utility model requires the interruption of media flow during maintenance. However, interrupting media flow in continuously operating hydraulic systems, such as industrial production lines and construction machinery, would severely impact production efficiency due to downtime for maintenance. Furthermore, the operation of interrupting media flow would increase the overall maintenance time, making the maintenance process cumbersome. Therefore, to address these shortcomings, the inventors propose a hydraulic pipe valve that facilitates maintenance. Utility Model Content

[0004] The main purpose of this utility model is to provide a hydraulic pipe valve that is easy to maintain. It can effectively solve the problem that in the prior art, when maintaining a hydraulic pipe valve, it is necessary to cut off the flow of the medium. However, cutting off the flow of the medium would seriously affect the production efficiency of continuously operating hydraulic systems such as industrial production lines and construction machinery.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hydraulic pipe valve that is easy to maintain includes a valve, wherein the valve has connecting pipes at both its inlet and outlet, and a parallel pipe is fixedly connected between the two connecting pipes. The connecting pipe has a first closing chamber inside, and a first baffle is slidably connected inside the first closing chamber. The parallel pipe has second closing chambers on both sides inside, and a second baffle is slidably connected inside both second closing chambers.

[0007] Preferably, a first movable rod is fixedly installed on one side of the first baffle, and the end of the first movable rod away from the first baffle extends to the outside of the first closing cavity and is fixedly installed with a drive head. A first spring is fixedly connected between the drive head and the outer surface of the first closing cavity, and the first spring is sleeved on the outer end of the first movable rod. A ball bearing is provided inside the drive head.

[0008] Preferably, a second movable rod is fixedly installed on one side of the second baffle, and the end of the second movable rod away from the second baffle extends to the outside of the second closing cavity and is fixedly installed with a connecting plate. A second spring is fixedly installed between the connecting plate and the outer surface of the second closing cavity, and the second spring is sleeved on the outer end of the second movable rod. A trigger plate is fixedly installed on one side of the connecting plate, and an embedding groove matching the ball is opened on one side of the trigger plate.

[0009] Preferably, dustproof cloth covers are fixedly installed between the driving head and the outer surface of the first closing cavity and between the connecting plate and the outer surface of the second closing cavity, and the two dustproof cloth covers are respectively located at the outer ends of the first spring and the second spring.

[0010] Preferably, an extrusion head is fixedly installed on one side of the connecting plate.

[0011] Preferably, a compression rod is fixedly installed on one side of the outer surface of the valve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model discloses a hydraulic pipe valve that is easy to maintain. By setting up parallel pipes, when the valve is disassembled from the two connecting pipes in actual operation, the extrusion head will be pushed back to its original position by the elastic force of the second spring due to the loss of the extrusion of the extrusion rod. The second movable rod will then drive the second baffle to move, so that it does not block the second closing chamber. When the trigger plate moves back to its original position with the connecting plate, the ball will roll into contact with the side of the trigger plate, which will push the drive head and the first movable rod to move, so that the first baffle blocks the first closing chamber. The medium that entered the connecting pipe will then enter the parallel pipe, thus facilitating the maintenance of the valve. Moreover, it is not necessary to cut off the flow of the medium when disassembling and maintaining the valve, so as to effectively avoid the impact on production efficiency due to downtime maintenance.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This utility model discloses a hydraulic pipe valve that is easy to maintain, such as Figure 1-5 As shown, it includes valve 1. Based on the relative movement of the valve core and valve body, valve 1 adjusts the parameters of the hydraulic system by changing the flow area, oil passage, or by utilizing the balance between hydraulic pressure and spring force.

[0022] Both the inlet and outlet of valve 1 are equipped with connecting pipes 3. The two connecting pipes 3 are connected to the inlet and outlet of valve 1 respectively through flanges. The other end of the two connecting pipes 3 are also connected to the external hydraulic pipeline through flanges.

[0023] Furthermore, a parallel pipe 2 is fixedly connected between the two connecting pipes 3. The inside of the connecting pipe 3 is provided with a first closing chamber 301. A first baffle 302 is slidably connected inside the first closing chamber 301. The first baffle 302 can move inside the first closing chamber 301, thereby blocking the inside of the first closing chamber 301. When the first baffle 302 blocks the inside of the first closing chamber 301, the medium will be unable to enter the valve 1 through the connecting pipe 3.

[0024] The parallel pipe 2 has a second closing cavity 208 on both sides inside, and a second baffle 201 is slidably connected inside the two second closing cavities 208. The second baffle 201 can move inside the second closing cavity 208, thereby blocking the second closing cavity 208, so that the medium entering the connecting pipe 3 cannot flow through the parallel pipe 2.

[0025] A first movable rod 304 is fixedly installed on one side of the first baffle 302, and the end of the first movable rod 304 away from the first baffle 302 extends to the outside of the first closing cavity 301 and is fixedly installed with a drive head 305. When the drive head 305 moves, it will drive the first movable rod 304 and the first baffle 302 to move.

[0026] A first spring 303 is fixedly connected between the drive head 305 and the outer surface of the first closing cavity 301, and the first spring 303 is sleeved on the outer end of the first movable rod 304. The drive head 305 is provided with a ball 306 inside, which can rotate freely inside the drive head 305. When the drive head 305 moves toward the first spring 303, it will squeeze the first spring 303, and then the first movable rod 304 will push the first baffle 302 to move, so as to seal the inside of the first closing cavity 301.

[0027] When the compressed first spring 303 pushes the drive head 305 to reset, the first baffle 302 will reset and open the first closing cavity 301.

[0028] A second movable rod 202 is fixedly installed on one side of the second baffle 201, and the end of the second movable rod 202 away from the second baffle 201 extends to the outside of the second closing cavity 208 and is fixedly installed with a connecting plate 204. When the connecting plate 204 moves, it will drive the second movable rod 202 and the second baffle 201 to move.

[0029] A second spring 203 is fixedly installed between the connecting plate 204 and the outer surface of the second closing cavity 208, and the second spring 203 is sleeved on the outer end of the second movable rod 202. When the connecting plate 204 moves toward the second spring 203, it will squeeze the second spring 203 and drive the second movable rod 202 and the second baffle 201 to move, so that the second baffle 201 seals the second closing cavity 208.

[0030] When the connecting plate 204 is reset due to the elastic force of the second spring 203, the second baffle 201 will open the second closing cavity 208.

[0031] A trigger plate 205 is fixedly installed on one side of the connecting plate 204, and an embedding groove 206 matching the ball 306 is provided on one side of the trigger plate 205. The trigger plate 205 is arc-shaped.

[0032] Dustproof cloth covers 307 are fixedly installed between the drive head 305 and the outer surface of the first closing cavity 301 and between the connecting plate 204 and the outer surface of the second closing cavity 208. The two dustproof cloth covers 307 are located at the outer ends of the first spring 303 and the second spring 203, respectively. The dustproof cloth covers 307 can effectively prevent external dust or impurities from entering the gap between the first spring 303 and the second spring 203.

[0033] A compression head 207 is fixedly installed on one side of the connecting plate 204, and a compression rod 101 is fixedly installed on one side of the outer surface of the valve 1.

[0034] The working principle of this utility model is as follows: The operator installs two connecting pipes 3 into the hydraulic pipeline through flange connection. Then, the operator pushes the two extrusion heads 207 to move away from each other. During the movement of the extrusion heads 207, they will compress the second spring 203, thereby causing the second movable rod 202 and the second baffle 201 to move. The two second baffles 201 will then block the two second closing chambers 208. At this time, the operator places the valve 1 between the two extrusion heads 207, and the extrusion rod 101 will contact the two extrusion heads 207. Due to the blocking of the extrusion rod 101, the two extrusion heads 207 will not return to their original position due to the elasticity of the second spring 203. Then, the valve 1 can be connected to the two connecting pipes 3 through the flange. At this time, since the ball 306 does not contact the trigger plate 205, the first closing chamber 301 is in the open state.

[0035] When valve 1 is in operation, the medium transmitted through the hydraulic pipeline will enter the connecting pipe 3 and then enter the valve 1 through the connecting pipe 3, thereby transmitting the medium. When valve 1 needs to be disassembled for maintenance, after valve 1 is disassembled, since the compression rod 101 is no longer resisting, the second spring 203 will push the compression head 207 to reset, which will in turn drive the second movable rod 202 and the second baffle 201 to reset, so as to open the second closing chamber 208.

[0036] When the extrusion head 207 and the connecting plate 204 are reset, the trigger plate 205 will move. The trigger plate 205 will then roll into contact with the ball 306, which will push the ball 306 and the drive head 305 to move. This will cause the drive head 305 to squeeze the first spring 303 and drive the first movable rod 304 and the first baffle 302 to move. The first baffle 302 will then block the first closing chamber 301 until the ball 306 moves into the embedded groove 206. At this time, the valve 1 has been disassembled and repaired. The medium that enters the connecting pipe 3 through the external hydraulic pipeline will enter the parallel pipe 2 and continue to be transmitted through the parallel pipe 2. This allows the valve 1 to be disassembled and cleaned without cutting off the flow of the medium.
