Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and in particular to a two-position two-way solenoid valve that is easy to connect. Background Technology

[0002] Two-position, two-way solenoid valves are commonly used fluid control components, widely applied in industrial automation, medical equipment, environmental engineering, and household appliances. Their main function is to control the movement of the valve core via electromagnetic force, thereby achieving fluid flow control. Existing two-position, two-way solenoid valves typically include a valve body, an electromagnetic drive unit, and an interface structure for connecting the delivery pipe.

[0003] In practical applications, solenoid valves typically need to be connected to external delivery pipes to enable fluid input and output. Currently, the most common connection method is threaded connection, where either the solenoid valve itself or the delivery pipe is rotated to secure it. However, this traditional connection method has significant limitations: when the solenoid valve is installed in confined spaces, in compact equipment, or in environments with dense piping, rotating the solenoid valve or delivery pipe becomes extremely difficult, or even impossible, due to limited operating space. This not only increases the difficulty of installation and maintenance but also easily leads to loose connections due to improper operation, causing leakage risks and affecting the reliability and safety of the system.

[0004] Although some improved solenoid valve structures exist in the prior art, such as those using quick-connect couplings or flange connections, these structures are often costly and bulky, making them unsuitable for all applications, especially those with strict space and cost requirements. Therefore, a two-position, two-way solenoid valve that is easy to connect is provided to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a two-position two-way solenoid valve that is easy to connect, in order to solve the technical problem that existing two-position two-way solenoid valves are not easy to connect to delivery pipes in confined spaces.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A two-position two-way solenoid valve that is easy to connect includes a supporting housing and a valve body. The valve body has an inlet end and an outlet end at its two ends, respectively. The inlet end has an inlet channel formed inside, and the outlet end has an outlet channel formed inside. The supporting housing is equipped with an on / off module for controlling the opening and closing of the inlet channel and the outlet channel. Both the inlet and outlet ends are provided with connecting assemblies for threaded connection with different delivery pipes respectively; the connecting assembly on the outlet end includes a connecting sleeve, one end of which is rotatably disposed inside the outlet end, and the inner side wall of this end is provided with an internal thread for threaded connection with the outer side wall of the delivery pipe.

[0007] Furthermore, the on / off module includes a connecting frame and a mounting frame installed inside the supporting housing. The connecting frame is detachably equipped with a connecting cylinder, both ends of which extend to the outside of the supporting housing. A connecting sleeve is formed in the middle of the valve body, and a connecting part is formed at one end of the connecting cylinder. The connecting part is inserted into the connecting sleeve and fixedly connected thereto. A buffer channel communicating with the liquid inlet channel is formed inside the connecting sleeve. A valve hole for communicating with the liquid outlet channel is provided inside the valve body. A sealing element for blocking the end away from the connecting part is provided inside the connecting cylinder. A valve assembly for controlling the on / off of the valve hole is installed inside the connecting cylinder.

[0008] Furthermore, the outer surface of the end of the connecting sleeve located outside the liquid outlet is provided with a rotating part, and several anti-slip protrusions are formed around the rotating part.

[0009] Furthermore, a rotating ring is provided on the outer side of the end of the connecting sleeve that is rotatably set with the liquid outlet end, and an annular groove coaxially set with the connecting sleeve is formed inside the liquid outlet end, with the rotating ring rotatably set in the annular groove.

[0010] Furthermore, several balls are rotatably arranged on both radial sides of the rotating ring, and the balls roll into contact with the inner sidewall of the annular groove.

[0011] Furthermore, an annular boss is provided between the end of the connecting sleeve with the internal thread and the liquid outlet channel. The boss is coaxially arranged with the connecting sleeve, and a first sealing ring is provided on the side of the boss near the connecting sleeve to improve the sealing performance.

[0012] Furthermore, the inner side of the boss is provided with an extension that extends away from the liquid outlet channel. The extension is annular and is used to insert into the inside of the delivery pipe. Several second sealing rings are provided on the outer side of the extension.

[0013] Furthermore, the mounting bracket is placed inside the connecting bracket, and the connecting cylinder is inserted through the mounting bracket. The outer surface of the end of the connecting cylinder away from the connecting part is provided with external threads. The end of the connecting cylinder with the connecting part is also provided with a limiting protrusion for abutting against the connecting bracket. The end of the connecting cylinder with external threads is threaded with a nut. After the nut is tightened, it cooperates with the limiting protrusion to lock the connecting cylinder onto the connecting bracket.

[0014] Furthermore, the valve assembly includes an electromagnet movably disposed inside the connecting cylinder. The electromagnet can move toward or away from the valve orifice. The end of the electromagnet away from the seal extends into the buffer channel, and a sealing plug for blocking the valve orifice is fixedly disposed at this end. A placement chamber is formed inside the electromagnet, and a spring is disposed in the placement chamber. One end of the spring is connected to the seal, and the other end is connected to the sealing plug. The spring is used to apply a force to the sealing plug toward the valve orifice.

[0015] Furthermore, the mounting bracket is wound with a coil that is sleeved on the outside of the connecting cylinder, and the connecting bracket is equipped with a number of pins for electrical connection with the coil, with the energized end of the pins extending through the supporting housing to its outside.

[0016] The beneficial effects of this utility model are as follows: In use, after inserting the threaded end of the delivery pipe into the connecting sleeve, rotating the connecting sleeve allows the internal thread of the connecting sleeve to engage with the external thread of the delivery pipe, thus threading the connecting sleeve and the delivery pipe together. Simultaneously, the delivery pipe is connected to the liquid outlet channel inside the liquid outlet end (the other delivery pipe is connected to the liquid inlet channel inside the liquid inlet end). The on / off module is then activated to control the flow of the delivery pipe. The connection to the delivery pipe is achieved simply by rotating the connecting sleeve, allowing for connection without needing to rotate the solenoid valve or the delivery pipe. This makes the solenoid valve easy to connect and use even in confined spaces, improving ease of use. Attached Figure Description

Detailed Implementation

[0023] The following is a detailed description of a two-position, two-way solenoid valve of this utility model that is easy to connect, with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, an embodiment of the present invention, a two-position two-way solenoid valve for easy connection, includes a supporting housing 1 and a valve body 11. A connecting frame 2 and a mounting frame 3 are installed inside the supporting housing 1. The mounting frame 3 is located inside the connecting frame 2. A connecting cylinder 4 is detachably mounted on the connecting frame 2, and the connecting cylinder 4 passes through the mounting frame 3. Both ends of the connecting cylinder 4 extend to the outside of the supporting housing 1. A connecting sleeve 115 is formed in the middle of the valve body 11. A connecting portion 10 is formed at one end of the connecting cylinder 4 extending to the outside of the supporting housing 1. The connecting portion 10 is inserted into the connecting sleeve 115 and fixedly connected thereto. Figure 2 For example, the connecting cylinder 4 is first passed through the supporting shell 1 from bottom to top, and simultaneously passed through the connecting frame 2 and the mounting frame 3. At this time, both ends of the connecting cylinder 4 extend to the outside of the supporting shell 1. Then, the connecting cylinder 4 is fixedly installed on the connecting frame 2, so that the connecting part 10 on the connecting cylinder 4 is arranged downward. Then, the connecting part 10 is inserted into the connecting sleeve 115, and the connecting part 10 is fixedly connected to the connecting sleeve 115. While fixing, a seal is also performed to realize the installation of the connecting cylinder 4 and the valve body 11.

[0025] In addition, a third sealing ring 20 is provided between the outer wall of the connecting part 10 and the inner wall of the connecting sleeve 115. By providing the third sealing ring 20, the sealing effect is further improved after the connecting part 10 and the connecting sleeve 115 are sealed and fixedly connected, thus preventing the liquid inside the valve body 11 from leaking out.

[0026] In this embodiment, the valve body 11 has an inlet end 12 and an outlet end 13 symmetrically arranged based on the connecting sleeve 115 at both ends. The inlet end 12 has an inlet channel 111 formed inside, and the outlet end 13 has an outlet channel 112 formed inside. The connecting sleeve 115 has a buffer channel 113 that communicates with the inlet channel 111. The valve body 11 has a valve hole 114 inside for communicating with the buffer channel 113 and the outlet channel 112. The connecting sleeve 4 has a sealing element 15 inside for blocking the end away from the connecting part 10. The connecting sleeve 4 has a valve assembly inside for controlling the opening and closing of the valve hole 114. When the valve assembly is energized, the valve assembly operates to open the valve port 114, so that the buffer channel 113 and the liquid outlet channel 112 are connected through the valve port 114. The liquid or gas to be transported flows sequentially through the liquid inlet channel 111, the buffer channel 113, the valve port 114 and the liquid outlet channel 112. Furthermore, by providing the sealing element 15, the liquid or gas cannot leak out from the inside of the connecting cylinder 4.

[0027] To enable this solenoid valve to connect to two delivery pipes 21 used for conveying liquid or gas, both the inlet end 12 and the outlet end 13 are equipped with connecting assemblies 14 for threaded connection to different delivery pipes 21, respectively. The connecting assemblies 14 at both ends connect the different delivery pipes 21 to the inlet channel 111 and the outlet channel 112, respectively. Figure 1 As shown, after inserting the ends of different delivery pipes 21 into the connecting assemblies 14 at both ends of the valve body 11, tighten the connecting assemblies 14 at both ends to make the inlet end 12 and outlet end 13 threadedly sealed to the ends of different delivery pipes 21. This allows for connection without rotating the solenoid valve or delivery pipes 21, making the solenoid valve easy to connect and install even in confined spaces, thus improving ease of use. The specific threaded connection method is detailed below.

[0028] To allow the connecting cylinder 4 to be detachably mounted on the connecting frame 2, the outer surface of the end of the connecting cylinder 4 away from the connecting part 10 is provided with external threads. The end of the connecting cylinder 4 with the connecting part 10 is also provided with a limiting protrusion 5 for abutting against the connecting frame 2. A nut 7 is threadedly connected to the threaded end of the connecting cylinder 4. After the nut 7 is tightened, it cooperates with the limiting protrusion 5 to lock the connecting cylinder 4 onto the connecting frame 2. The connecting cylinder 4 passes through the supporting shell 1 from bottom to top, and simultaneously passes through the connecting frame 2 and the mounting frame 3. The limiting protrusion 5 abuts against one side of the connecting frame 2. After the nut 7 is put on the outside of the threaded end of the connecting cylinder 4 and tightened, the nut 7 abuts against the other side of the connecting frame 2. With the cooperation of the nut 7 and the limiting protrusion 5, the connecting cylinder 4 is mounted on the connecting frame 2. However, after unscrewing the nut 7, the connecting cylinder 4 can be removed from the inside of the supporting shell 1, completing the disassembly.

[0029] A gasket 6 is provided between the nut 7 and the connecting bracket 2. The gasket 6 is provided to distribute pressure and provide a smooth bearing surface.

[0030] The connecting assembly 14 on the inlet end 12 and the connecting assembly 14 on the outlet end 13 have the same structure and operate in the same way, such as Figure 3-4 As shown, the connecting assembly 14 on the liquid outlet 13 includes a connecting sleeve 141 coaxially arranged with the liquid outlet channel 112. One end of the connecting sleeve 141 is rotatably disposed inside the liquid outlet 13, and the inner side wall of this end is provided with an internal thread 147 for threaded connection with the outer side wall of the delivery pipe 21.

[0031] After inserting the threaded end of the delivery pipe 21 into the connecting sleeve 141, rotate the connecting sleeve 141. With the internal thread 147 of the connecting sleeve 141 engaging with the external thread of the delivery pipe 21, the connecting sleeve 141 and the delivery pipe 21 are threadedly connected. At the same time, the delivery pipe 21 is connected to the liquid outlet channel 112. By rotating the connecting sleeve 141, it can be connected to the delivery pipe 21 for easy connection and use by the user.

[0032] To facilitate the user's rotation of the connecting sleeve 141, a rotating part 145 is provided on the outer surface of the end of the connecting sleeve 141 located outside the liquid outlet 13. Several anti-slip protrusions 146 are formed around the rotating part 145. When it is necessary to rotate the connecting sleeve 141, the user only needs to turn the rotating part 145. Furthermore, by providing several anti-slip protrusions 146, the friction is increased, and the anti-slip effect is improved.

[0033] A rotating ring 142 is provided on the outer side of the end of the connecting sleeve 141 that is rotatably disposed with the liquid outlet 13. An annular groove 143 coaxially disposed with the connecting sleeve 141 is formed inside the liquid outlet 13, and the rotating ring 142 is rotatably disposed within the annular groove 143. By providing the rotating ring 142 and the annular groove 143, the end of the connecting sleeve 141 is rotatably disposed inside the liquid outlet 13.

[0034] A plurality of balls 144 are rotatably provided on both radial sides of the rotating ring 142, and the balls 144 roll in contact with the inner sidewall of the annular groove 143. By providing a plurality of balls 144, the friction between the rotating ring 142 and the annular groove 143 is reduced, avoiding jamming due to long-term inactivity, and also improving the feel of the connecting sleeve 141 when rotating.

[0035] To improve the sealing performance after the connecting sleeve 141 is connected to the liquid outlet 13, an annular boss 148 is provided between the end of the connecting sleeve 141 with the internal thread 147 and the liquid outlet channel 112. The boss 148 is coaxially arranged with the connecting sleeve 141, and a first sealing ring 149 is provided on the side of the boss 148 near the connecting sleeve 141 to improve the sealing performance. During the rotation of the connecting sleeve 141, the end of the delivery pipe 21 will move towards the boss 148 under the action of the thread. When the connecting sleeve 141 and the end of the delivery pipe 21 are tightened, the end of the delivery pipe 21 will contact the first sealing ring 149, so that the first sealing ring 149 fills the gap between the end of the delivery pipe 21 and the side of the boss 148, preventing liquid or gas leakage after the solenoid valve is opened.

[0036] The inner side of the boss 148 is provided with an extension 1410 extending away from the liquid outlet channel 112. The extension 1410 is annular and is used to insert into the interior of the delivery pipe 21. Several second sealing rings 1411 are provided on the outer side of the extension 1410. When the end of the delivery pipe 21 is inserted into the connecting sleeve 141, the extension 1410 is inserted into the interior of the delivery pipe 21. The several second sealing rings 1411 are filled between the outer wall of the extension 1410 and the inner wall of the delivery pipe 21. Under the double sealing effect of the first sealing ring 149 and the several second sealing rings 1411, the sealing effect after connection is further improved.

[0037] The valve assembly includes an electromagnet 16 movably disposed inside the connecting cylinder 4. The electromagnet 16 can be an electromagnet (i.e., a valve core) made of soft magnetic material. The electromagnet 16 can move toward or away from the valve hole 114. The end of the electromagnet 16 away from the seal 15 extends into the buffer channel 113, and a sealing plug 17 for blocking the valve hole 114 is fixedly provided at this end. A placement chamber 18 is formed inside the electromagnet 16. A spring 19 is provided in the placement chamber 18. One end of the spring 19 is connected to the seal 15, and the other end is connected to the sealing plug 17. The spring 19 is used to apply a force to the sealing plug 17 toward the valve hole 114. The sealing plug 17 can be a silicone plug.

[0038] When the spring 19 is in its initial state, it is slightly compressed, which applies force to the sealing plug 17 to block the valve hole 114. After applying a force to the electromagnet 16 away from the valve hole 114, the electromagnet 16 moves the sealing plug 17 away from the valve hole 114. The spring 19 is compressed, and after the end of the electromagnet 16 away from the sealing plug 17 contacts the seal 15, the sealing plug 17 disengages from the valve hole 114, connecting the buffer channel 113 with the valve hole 114, forming a liquid flow channel through the inlet channel 111, the buffer channel 113, the valve hole 114, and the outlet channel 112. After the force applied to the electromagnet 16 is stopped, the compression spring 19 pushes the electromagnet 16 and the sealing plug 17 to reset, and the sealing plug 17 blocks the valve hole 114 again, disconnecting the buffer channel 113 from the valve hole 114, thus achieving on / off control.

[0039] Additionally, the mounting bracket 3 is wound with a coil 8 that is sleeved on the outside of the connecting cylinder 4. The connecting bracket 2 is equipped with several pins 9 for electrical connection with the coil 8. The energized ends of the pins 9 extend through the supporting housing 1 to its outside. The energized ends of the pins 9 are used to connect the positive and negative terminals of the power supply, thereby energizing the coil 8. When current passes through the coil 8 sleeved on the outside of the connecting cylinder 4, according to the principle of "electromagnetism", the coil 8 generates a strong and concentrated magnetic field. The magnetic field lines will be conducted along the magnetic circuit. The magnetic field will pass through the mounting bracket 3 and the cylinder wall of the connecting cylinder 4, concentrate in the cavity inside, and act on the electromagnet 16. The electromagnet 16 is strongly magnetized (i.e., induced magnetization) and instantly becomes a magnet. According to the principle of "opposite poles attract", the magnetized electromagnet 16 will be subjected to an electromagnetic attraction force toward the center of the magnetic field (i.e., the center of the coil 8). This attraction force is greater than the elastic force of the spring 19, thereby controlling the movement of the electromagnet 16 inside the connecting cylinder 4.

[0040] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
