Description

Technical Field

[0001] This utility model relates to the field of gas distribution control valve technology, specifically a shock-resistant gas distribution valve capable of switching gas direction. Background Technology

[0002] A gas distribution valve provides a branch of air supply to pneumatic equipment in an industrial automation control system, reducing manual operation and facilitating the control of various pipelines. It serves as an intermediate bridge connecting centrally installed pneumatic equipment to the main air supply pipeline. With two sets of air paths, the gas direction can be switched by controlling the valve body's opening and closing. Chinese utility model patent CN209409743U discloses a gas direction switching distribution valve for an air suspension system. This valve includes a gas direction control mechanism for switching the flow direction of gas between an air tank and an air spring. The gas direction control mechanism includes a gas pipeline unit, an air compressor, and a solenoid valve control unit. The gas pipeline unit includes a first gas pipeline connected to the air spring and a second gas pipeline connected to the air tank. The solenoid valve control unit includes a single-way solenoid valve, a first three-way solenoid valve connected to the air compressor's outlet, and a second three-way solenoid valve connected to the air compressor's inlet. Both the first and second three-way solenoid valves are connected to the first and second gas pipelines. The electromagnetic distribution valve body designed in this utility model can not only switch the direction of gas inlet and outlet, but also detect the pressure in the air suspension system. It is also convenient to process and produce, and reduces manufacturing costs.

[0003] Existing gas distribution control valves capable of switching gas directions have issues with the stability of external pipeline connections and insufficiently robust installation structures. Generally, the gas distribution control valve is securely fixed to the installation structure for vibration resistance. For example, the vibration-resistant rotary gas distribution valve proposed in patent announcement number CN216618694U is fixed to the work site through the connection holes in the base plate. Then, a positioning frame is snapped onto both ends of the rotary gas distribution valve. After snapping, the positioning frame is placed inside the lower positioning block, and then the upper positioning block is snapped onto both ends of the upper positioning frame, allowing the positioning block to slide on the surface of the threaded column. The upper positioning block is then fixedly connected via a connecting plate, and finally, a nut is threaded onto the threaded column, thus securing the rotary gas distribution valve and strengthening it, thereby enhancing its vibration resistance. However, if the installation structure cannot be stably installed within the equipment, it will still lack vibration resistance. Therefore, we propose a vibration-resistant gas distribution valve capable of switching gas directions to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-resistant gas distribution valve capable of switching gas direction, in order to solve the problems mentioned in the background art, such as the need to improve the stability of the external pipeline connection of the existing gas distribution control valve capable of switching gas direction, and the insufficient tightness of the installation structure. Generally, the gas distribution control valve is fixed tightly to the installation structure to achieve shock resistance, but if the installation structure cannot be stably installed in the equipment, it will also fail to resist shock.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant gas distribution valve capable of switching gas direction, comprising a gas distribution valve body, a first gas pipe, a second gas pipe, and a third gas pipe;

[0006] The left end of the gas distribution valve body is fixed with a first gas pipe, and the left end of the first gas pipe is sequentially equipped with a first control valve and a second control valve from top to bottom, and the top end of the first gas pipe is fixed with a third control valve.

[0007] A distribution pipe is fixed to the bottom end of the gas distribution valve body, and a distribution control valve is installed on the distribution pipe. A second gas pipe is installed on the right end of the gas distribution valve body, and a third gas pipe is arranged above the second gas pipe. A fourth control valve is installed at the front end of both the second and third gas pipes. A pipe limiting plate is arranged on the outside of the gas distribution valve body. The pipe limiting plate has equally spaced grooves inside, and a connecting rod is fixed to the outer end of the pipe limiting plate. A first mounting plate is fixed to the outer end of the gas distribution valve body, and a second mounting plate is arranged on the outside of the gas distribution valve body. A manual telescopic rod is fixed to the outer side of the second mounting plate, and a fastening plate is fixed to the output end of the manual telescopic rod.

[0008] Preferably, the pipe limiting plate, the groove, and the connecting rod constitute a pipe limiting structure.

[0009] Preferably, the connection between the connecting rod and the gas distribution valve body is a threaded connection.

[0010] Preferably, the second mounting plate is fixedly connected to the first mounting plate by screws, and the outer side of the first mounting plate is flush with the outer side of the gas distribution valve body.

[0011] Preferably, the front and rear sides and the upper and lower sides of the gas distribution valve body are all fixed with a first mounting plate.

[0012] Preferably, the second mounting plate, the manual telescopic rod, and the fastening plate constitute a pressure-resistant structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the shock-resistant gas distribution valve that can switch the gas direction avoids the external pipeline from detaching from the gas distribution valve body, facilitates the disassembly and assembly of the pipeline limiting structure, increases the installation stability of the gas distribution valve body, and improves the shock resistance performance.

[0014] 1. The pipe limiting plate, cable tray and connecting rod constitute the pipe limiting structure. The external pipe passes through three sets of cable trays, which can limit the external pipe and prevent the external pipe from detaching from the gas distribution valve body;

[0015] The connection between the connecting rod and the gas distribution valve body is a threaded connection, which facilitates the disassembly and assembly of the connecting rod and the gas distribution valve body, thereby facilitating the disassembly and assembly of the pipeline limiting structure consisting of the pipeline limiting plate, the cable tray and the connecting rod.

[0016] 2. Gas can flow from the first gas pipe to the second gas pipe, and from the third gas pipe to the first gas pipe, changing the flow direction of gas inside the gas distribution valve body;

[0017] 3. The gas distribution valve body is pressed between other workpieces by the pressure structure consisting of the second mounting plate, the manual telescopic rod and the fastening plate, which increases the installation stability of the gas distribution valve body and improves its shock resistance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-5 The stability of the external pipeline connection of existing gas distribution control valves capable of switching gas direction needs to be improved. In order to solve this technical problem, this embodiment discloses the following technical content.

[0026] An earthquake-resistant gas distribution valve capable of switching gas direction is provided. A first gas pipe 2 is fixed to the left end of the gas distribution valve body 1. A first control valve 3 and a second control valve 4 are installed sequentially from top to bottom on the left end of the first gas pipe 2. A third control valve 5 is fixed to the top end of the first gas pipe 2. A distribution pipe 6 is fixed to the bottom end of the gas distribution valve body 1. A distribution control valve 7 is installed on the distribution pipe 6. A second gas pipe 8 is installed to the right end of the gas distribution valve body 1. A third gas pipe 9 is provided above the second gas pipe 8. A fourth control valve 10 is installed at the front end of both the second gas pipe 8 and the third gas pipe 9. A first mounting plate 14 is fixed to the outer end of the gas distribution valve body 1.

[0027] The distribution pipe 6 is connected to an external pipe. The first control valve 3, the distribution control valve 7, and the fourth control valve 10 on the second gas pipe 8 are opened. The second control valve 4, the third control valve 5, and the fourth control valve 10 on the third gas pipe 9 are closed. Gas flows downward from the first gas pipe 2 to the external pipe of the distribution pipe 6. A portion of the gas flows out from the second gas pipe 8.

[0028] When switching the gas direction, close the first control valve 3, the distribution control valve 7, and the fourth control valve 10 on the second gas pipe 8; open the second control valve 4, the third control valve 5, and the fourth control valve 10 on the third gas pipe 9. Gas flows from the third gas pipe 9 to the gas distribution valve body 1, then to the top of the first gas pipe 2, and exits from the left end of the first gas pipe 2. Figure 1 The scissors shown are for two different gas flow directions;

[0029] When connecting external pipes to the distribution pipe 6, the second gas pipe 8, and the third gas pipe 9, insert the external pipes into the outer ends of the distribution pipe 6, the second gas pipe 8, and the third gas pipe 9, and then pass the external pipes through the three sets of wire grooves 12 inside the pipe limiting plate 11 in sequence. The external pipes are limited by the pipe limiting plate 11 and the wire grooves 12 to prevent the external pipes from easily falling off.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. The pipe limiting structure composed of the pipe limiting plate 11, the cable groove 12, and the connecting rod 13 is inconvenient to disassemble and assemble. To solve this technical problem, this example discloses the following technical content: Figures 1-3 As shown;

[0031] A pipe limiting plate 11 is provided on the outside of the gas distribution valve body 1. The pipe limiting plate 11 has equally spaced grooves 12 inside, and a connecting rod 13 is fixed at the outer end of the pipe limiting plate 11. The connection between the connecting rod 13 and the gas distribution valve body 1 is a threaded connection.

[0032] When it is necessary to remove the pipeline limiting structure, rotate the connecting rod 13 to separate the connecting rod 13 from the gas distribution valve body 1, thereby removing the pipeline limiting structure;

[0033] Example 3: Existing gas distribution control valves capable of switching gas directions have insufficiently robust installation structures, resulting in poor seismic resistance. To address this technical problem, this example discloses the following technical details. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 4 and Figure 5 ;

[0034] A second mounting plate 15 is provided on the outer side of the gas distribution valve body 1. A manual telescopic rod 16 is fixed on the outer side of the second mounting plate 15, and a fastening plate 17 is fixed on the output end of the manual telescopic rod 16. The second mounting plate 15 is fixedly connected to the first mounting plate 14 by screws, and the outer side of the first mounting plate 14 is flush with the outer side of the gas distribution valve body 1. The first mounting plate 14 is fixed on the front and rear sides and the upper and lower sides of the gas distribution valve body 1. The second mounting plate 15, the manual telescopic rod 16 and the fastening plate 17 constitute a pressure-resistant structure.

[0035] The gas distribution valve body 1 is first fixed inside the equipment with screws (the connection between the gas distribution valve body 1 and the equipment via screws is a conventional device and is not described in detail in the text). Then, the second mounting plate 15 is fixed to the first mounting plate 14 with screws. Then, the length of the manual telescopic rod 16 is adjusted so that the fastening plate 17 fits tightly with other workpieces inside the equipment, thereby holding the gas distribution valve body 1 in place. This makes the gas distribution valve body 1 more stable in installation and improves its shock resistance.

[0036] The above completes a series of operations for the shock-resistant gas distribution valve capable of switching gas direction. Any content not described in detail in this specification is prior art known to those skilled in the art.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
