Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic valve connection technology, specifically an electromagnetic valve connection structure. Background Technology
[0002] Solenoid valves are electromagnetically controlled industrial devices and are basic automated components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic systems. Solenoid valves can be used with different circuits to achieve the desired control, while ensuring both control accuracy and flexibility. Different solenoid valves play different roles in the control system. Most existing solenoid valve connection structures use threaded connections, but some pipelines do not have threaded openings on the outside when connecting to solenoid valves.
[0003] For example, prior art publication CN216896213U provides a connection structure for a solenoid valve, including a solenoid valve body. A first connecting pipe and a second connecting pipe are detachably connected to both ends of the solenoid valve body. One end of the first connecting pipe is fixedly connected to a first connecting part, and one end of the second connecting pipe is fixedly connected to a second connecting part, which is threadedly connected to the solenoid valve body. This connection structure for the solenoid valve, by providing the first and second connecting pipes, allows for direct insertion and connection to a pipeline.
[0004] While this device offers numerous advantages, it still suffers from the following drawbacks: It connects the pipe to the pipeline via a simple plug-in method, failing to secure the pipe to the pipeline. Furthermore, the high pressure within the pipeline often makes the pipe prone to detachment. Therefore, we propose a solenoid valve connection structure. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, which rely solely on plug-in connections and are prone to detachment between pipes and connecting tubes, this invention proposes a solenoid valve connection structure.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The solenoid valve connection structure of this utility model includes a solenoid valve body. Both the inlet and outlet ports of the solenoid valve body can be assembled and connected with a type I connection part and a type II connection part. The type I connection part includes a body connecting pipe one, a boss one, a pipe connecting pipe one for connecting the conveying pipe, a clamping plate, and a nut. The type II connection part includes a body connecting pipe two, a boss two, and a pipe connecting pipe two. In the type I connection part, when connecting to a conveying pipe without a threaded joint, in addition to directly inserting the pipe connecting pipe one into the conveying pipe so that the conveying pipe can be connected to the solenoid valve body, the clamping plate is tightened inward by tightening the nut to clamp the conveying pipe, so that the conveying pipe and the solenoid valve body can be fixedly connected, thereby preventing the solenoid valve body from falling off due to excessive internal pressure.
[0007] Preferably, the inner walls of both the inlet and outlet ports of the solenoid valve body are threaded, and the outer walls of the first body connecting pipe of the type I connection part and the second body connecting pipe of the type II connection part are threaded and are threadedly engaged with the inlet and outlet of the solenoid valve body, which facilitates the connection and assembly of the solenoid valve body with the type I connection part or the type II connection part.
[0008] Preferably, the first boss is installed at the end of the main body connecting pipe one of the type I connector that is away from the solenoid valve body. The other side of the first boss is connected to the first pipe connecting pipe. Clamping pieces are evenly arranged in an array on the same side of the first boss where the first pipe connecting pipe is installed. The outer diameter of the first pipe connecting pipe is the same as the inner diameter of the conveying pipe to be connected. A sealing gasket one is fitted to the side of the first boss connected to the first main body connecting pipe. A sealing gasket two is sleeved on the outer wall of the first pipe connecting pipe. The outer edge of the first boss is a polygonal structure. The type I connector facilitates connection with conveying pipes without threaded joints.
[0009] Preferably, the clamping plate has an arc-shaped structure, and the inner wall diameter of the clamping plate is the same as the outer wall diameter of the conveying pipe to be connected. The outer wall of the clamping plate is provided with threads, and a nut is connected to the outer side of the clamping plate through thread engagement. The inner side of the end of the clamping plate away from the first boss is evenly provided with protrusions. The clamping plate can clamp and fix the conveying pipe to prevent it from falling off.
[0010] Preferably, a boss is installed at one end of the body connecting pipe II of the type II connection part away from the solenoid valve body, and a pipe connecting pipe II is connected to the other side of the boss II. The outer wall of the pipe connecting pipe II is provided with a conveying pipe with a threaded interface for connection. The type II connection part facilitates the connection between the solenoid valve body and the conveying pipe with a threaded interface.
[0011] Preferably, the outer edge of the second boss is a polygonal structure, and sealing gaskets are fitted to both sides of the second boss.
[0012] The advantages of this utility model are:
[0013] 1. This utility model allows for the selection of different types of Type I or Type II connection parts to connect to the conveying pipeline at both ends of the solenoid valve body, depending on whether the pipeline has a threaded connection. This facilitates the use of different connection methods to connect to the conveying pipeline. In the Type I connection part, when connecting to a conveying pipeline without a threaded connection, in addition to directly inserting the pipeline connecting pipe into the conveying pipeline so that the conveying pipeline can be connected to the solenoid valve body, the clamping plate is also tightened inward by tightening the nut to clamp the conveying pipeline, thereby fixing the conveying pipeline and the solenoid valve body together and preventing the solenoid valve body from falling off due to excessive internal pressure.
[0014] 2. The Type II connecting part of this utility model facilitates connection with a conveying pipe with a threaded joint. The connection between the conveying pipe and the solenoid valve body is achieved through the threaded engagement, making the solenoid valve body more versatile and adaptable to different applications.

Detailed Implementation
[0021] 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 scope of protection of the present utility model.
[0022] Please see Figure 1 As shown, a solenoid valve connection structure includes a solenoid valve body 1. Both the inlet and outlet ports of the solenoid valve body 1 can be assembled and connected with a type I connection part 2 and a type II connection part 3. The type I connection part 2 includes a body connection pipe 4, a boss 5, a pipe connection pipe 6 for connecting a conveying pipe 9, a clamping plate 7, and a nut 8. The type II connection part 3 includes a body connection pipe 10, a boss 11, and a pipe connection pipe 12.
[0023] When connecting the solenoid valve body 1 to the delivery pipe 9, either a type I connection part 2 or a type II connection part 3 can be connected to the inlet and outlet of the solenoid valve body 1, depending on whether the delivery pipe 9 has a threaded joint. When connecting the type I connection part 2 to the delivery pipe 9 without a threaded joint, the pipe connecting tube 6 in the type I connection part 2 is directly inserted into the delivery pipe 9, and then the nut 8 is turned outward. The movement of the nut 8 causes the clamping plate 7 to retract inward, clamping and fixing the type I connection part 2 and the delivery pipe 9. When the solenoid valve body 1 needs to be connected to a pipe with a threaded joint, a type II connection part 3 can be connected to the port of the solenoid valve body 1. When connecting the solenoid valve body 1 to the delivery pipe 9 through the type II connection part 3, the pipe connecting tube 12 can be directly threaded to the threaded joint of the delivery pipe 9, so that the solenoid valve body 1 can be connected to the delivery pipe 9 with a threaded joint.
[0024] The inner walls of both the inlet and outlet ports of the solenoid valve body 1 are threaded. The outer walls of the body connecting pipe 1 4 of the type I connection part 2 and the outer walls of the body connecting pipe 2 10 of the type II connection part 3 are threaded and are threadedly engaged with the inlet and outlet ports of the solenoid valve body 1.
[0025] Threads are provided on the inner walls of the inlet and outlet ports of the solenoid valve body 1 to facilitate the connection between the solenoid valve body 1 and the type I connection part 2 or the type II connection part 3. This allows the solenoid valve body 1 to be connected to the conveying pipe 9 with or without threaded joints, making the solenoid valve body 1 more versatile and adaptable to different applications.
[0026] like Figure 2 As shown, a boss 5 is installed at the end of the main body connecting pipe 4 of the type I connecting part 2 away from the solenoid valve body 1. A pipe connecting pipe 6 is connected to the other side of the boss 5. Clamping pieces 7 are evenly arranged on the same side of the boss 5 where the pipe connecting pipe 6 is installed. The outer diameter of the pipe connecting pipe 6 is the same as the inner diameter of the conveying pipe 9 to be connected. A sealing gasket 501 is fitted to the side of the boss 5 connected to the main body connecting pipe 4. A sealing gasket 601 is sleeved on the outer wall of the pipe connecting pipe 6. The outer edge of the boss 5 has a polygonal structure.
[0027] When the solenoid valve body 1 is connected to the conveying pipe 9 without a threaded joint using the type I connecting part 2, firstly, the body connecting pipe 4 of the type I connecting part 2 is screwed into the port of the solenoid valve body 1 for threaded connection. Then, the pipe connecting pipe 6 of the type I connecting part 2 is directly inserted into the conveying pipe 9. When the body connecting pipe 4 is screwed into the port of the solenoid valve body 1, a wrench can be used to tighten the connection by locking it onto the boss 5. In addition, the sealing gasket 501 on the boss 5 can seal the port of the solenoid valve body 1 to prevent leakage, and the sealing gasket 601 on the pipe connecting pipe 6 can fill the gap between the pipe connecting pipe 6 and the conveying pipe 9 to improve the sealing performance.
[0028] like Figure 3 As shown, the clamping plate 7 has an arc-shaped structure, and the inner wall diameter of the clamping plate 7 is the same as the outer wall diameter of the conveying pipe 9 to be connected. The outer wall of the clamping plate 7 is provided with threads, and the outer side of the clamping plate 7 is connected to the nut 8 by thread engagement. The inner side of the clamping plate 7 at the end away from the boss 5 is uniformly provided with protrusions 701.
[0029] To prevent the pipe connector 6 from falling off when directly inserted into the conveying pipe 9, after the pipe connector 6 is inserted into the conveying pipe 9, the nut 8 can be turned to move away from the boss 5. Due to the compression of the nut 8, the clamping piece 7 contracts and clamps the outer wall of the conveying pipe 9. Furthermore, the protrusion 701 will be embedded into the outer wall of the conveying pipe 9 after being compressed by the nut 8, making the clamping and fixing more secure.
[0030] like Figure 4As shown, the body connecting pipe 2 10 of type II connection part 3 is equipped with a boss 2 11 at one end away from the solenoid valve body 1. The other side of the boss 2 11 is connected to a pipe connecting pipe 2 12. The outer wall of the pipe connecting pipe 2 12 is provided with a conveying pipe 9 with a threaded interface. The outer edge of the boss 2 11 is a polygonal structure. Both sides of the boss 2 11 are fitted with sealing gaskets 3 1101.
[0031] When the solenoid valve body 1 is connected to the pipe with a threaded joint using the type II connection part 3, the body connection pipe 10 of the type II connection part 3 is first screwed into the port of the solenoid valve body 1 through the threaded connection. When screwing in the body connection pipe 10, a wrench can be used to tighten it by gripping the boss 11. Then, the pipe connection pipe 12 of the type II connection part 3 is directly screwed into the threaded conveying pipe 9 through the thread. During the connection, the port of the pipe can be sealed and plugged by the sealing gasket 1101 to improve the sealing performance.
[0032] Working principle: When connecting the solenoid valve body 1 to the delivery pipe 9, either type I connection part 2 or type II connection part 3 can be connected to the inlet and outlet of the solenoid valve body 1, depending on whether the delivery pipe 9 has a threaded joint. When connecting the solenoid valve body 1 to the delivery pipe 9 without a threaded joint using type I connection part 2, the pipe connecting tube 6 in type I connection part 2 is directly inserted into the delivery pipe 9, and then the nut 8 is turned outward. The movement of the nut 8 causes the clamping plate 7 to retract inward, clamping and fixing the type I connection part 2 and the delivery pipe 9. When the solenoid valve body 1 needs to be connected to a pipe with a threaded joint, type II connection part 3 can be connected to the port of the solenoid valve body 1. When connecting to the delivery pipe 9 through type II connection part 3, pipe connecting tube 12 can be directly threaded to the threaded joint of the delivery pipe 9, so that the solenoid valve body 1 can be connected to the delivery pipe 9 with a threaded joint.
