Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve that can be stably connected. Background Art

[0002] The solenoid valve is both the interface between the electrical control part and the pneumatic actuator part, and also the interface with the gas source system. The solenoid valve receives commands to release, stop or change the flow direction of compressed gas. In electro-pneumatic control, the solenoid valve can achieve the following functions: the action of the pneumatic actuator to achieve gas ON / OFF switching control, and flow control with different opening sizes. The main working principle of the solenoid valve is to use the electromagnetic force generated by the solenoid valve coil to push the valve core to achieve airflow switching or flow control;

[0003] Publication (Announcement) No. CN215928704U discloses a pneumatic solenoid valve that can be quickly installed. This technology discloses that "it includes a solenoid valve body, with fixed pipes connected to both sides of the top of the solenoid valve body, and a connector fixed to the end of the fixed pipe away from the solenoid valve body. The utility model uses technical solutions such as the provision of elastic plates, triangular blocks, screw threads, and threaded sleeves, and has positioning blocks and positioning grooves to fix the pipe, preventing the pipe from slipping between the elastic plates, causing the solenoid valve body to separate from the pipe, requiring reinstallation, wasting a lot of time and significantly reducing installation efficiency. This installation method does not require the use of other tools, and the solenoid valve body can be installed by simply turning the threaded sleeve, which has the following technical effects: convenient and quick installation."

[0004] When the above design is in use, although the positioning block and the positioning groove fix the pipeline to prevent the pipeline from slipping out from between the elastic sheets, the positioning block is blocked by the elastic sheet D, and as the elastic sheet is squeezed, the positioning block and the positioning groove will be misaligned, making it difficult to quickly engage and lock. In addition, the elastic sheet can easily deform, causing the positioning block to detach from the positioning groove, reducing the connection stability of the solenoid valve and the pipeline. Therefore, we propose a solenoid valve that can be stably connected to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown:

[0027] A solenoid valve capable of stable connection comprises a solenoid valve body 1 and connecting pipes 2 arranged at connecting ends on both sides of the solenoid valve body 1.

[0028] In this embodiment: the existing device {publication (announcement) number}: CN215928704U discloses a pneumatic solenoid valve that can be quickly installed. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above-mentioned design is in use, although the positioning block and the positioning groove fix the pipeline to prevent the pipeline from slipping out from between the elastic sheets, the positioning block is blocked by the elastic sheet D, and as the elastic sheet is squeezed, the positioning block and the positioning groove will be misaligned, making it difficult to quickly engage and lock, and the elastic sheet is easily deformed, causing the positioning block to detach from the positioning groove, reducing the connection stability between the solenoid valve and the pipeline." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a connecting component 3 is added to this application document.

[0029] More specifically:

[0030] Going further:

[0031] like Figures 1-4 As shown:

[0032] A connecting assembly 3 is mounted on the solenoid valve body 1. The connecting assembly 3 includes a sealing gasket 301 provided between the solenoid valve body 1 and the connecting pipe 2 to enhance sealing, a fixing sleeve 302 welded to the surface of the solenoid valve body 1 near the connecting end, and connecting blocks 303 fixed to the surface of the fixing sleeve 302 in a symmetrical arrangement.

[0033] A locking block 304 is slidably connected to the connecting block 303. A spring 306 is fixed between the locking block 304 and the connecting block 303. A rectangular groove 308 that matches the locking block 304 is formed on the side of the connecting block 303 away from the fixing sleeve 302. The locking block 304 and the connecting block 303 are slidably connected through the rectangular groove 308.

[0034] The surface of the connecting pipe 2 is provided with a locking groove 307 for inserting the locking block 304;

[0035] In the elastic initial state of the spring 306, the locking block 304 partially extends from the rectangular slot 308 provided in the connecting block 303;

[0036] The inner cavity of the fixing sleeve 302 is in contact with the outer surface of the connecting pipe 2, and the inner side of the connecting block 303 is provided with an arc-shaped groove that is in close contact with the connecting pipe 2;

[0037] A telescopic rod 305 is fixed between the locking block 304 and the connecting block 303 on one side close to the spring 306 , and the spring 306 is sleeved on the surface of the telescopic rod 305 .

[0038] In this embodiment, when the solenoid valve with stable connection is used, when two sets of connecting pipes 2 are used to install the solenoid valve body 1, one end of one set of connecting pipes 2 is first inserted into the pipe connection end of the solenoid valve body 1;

[0039] During this process, the locking block 304 is aligned with the locking groove 307 provided on the connecting tube 2, and the connecting tube 2 is pushed to squeeze the solenoid valve body 1. At this time, one side of the sealing gasket 301 is blocked by the solenoid valve body 1, so that the connecting tube 2 squeezes and deforms the sealing gasket 301. The elastic deformation of the sealing gasket 301 material itself is mainly relied on to fill the gap at the connection part of the solenoid valve body 1 and the connecting tube 2, thereby preventing fluid leakage and achieving a sealing effect.

[0040] During this process, the locking block 304 slides on the connecting pipe 2. At this time, the locking block 304 drives the spring 306 to be in a stretched state. The provision of the telescopic rod 305 further improves the stability of the connection between the locking block 304 and the connecting block 303, and improves the movement effect of the locking block 304 in the rectangular groove 308 provided in the connecting block 303.

[0041] When the sealing gasket 301 is squeezed and deformed, the locking block 304 corresponds to the locking groove 307. Since the stretched spring 306 rebounds and resets, the locking block 304 is driven to slide in the rectangular groove 308 and quickly snap into the locking groove 307, thereby completing the connection and locking of the solenoid valve body 1 and the connecting pipe 2.

[0042] This structure, through the open rectangular groove 308, can intuitively observe the correspondence between the locking block 304 and the locking groove 307 opened in the connecting pipe 2, thereby improving the snap-on locking effect. Through the contraction force of the spring 306, the locking block 304 can always be inserted into the locking groove 307 opened in the connecting pipe 2, thereby improving the stability of the connection between the solenoid valve body 1 and the connecting pipe 2.

[0043] Going further;

[0044] In an optional embodiment, an edge of the locking block 304 close to the connecting pipe 2 is provided with an inclined chamfer.

[0045] In this embodiment, one side of the locking block 304 is provided with an inclined chamfer, so that the size of one end of the locking block 304 is smaller than the opening size of the locking groove 307 on the connecting pipe 2, thereby making it easier for the locking block 304 to be inserted into the locking groove 307.

[0046] Going further;

[0047] In an optional embodiment, the surface of the fixing sleeve 302 is threadedly connected to a threaded ring 309 via a threaded groove;

[0048] The inner diameter of the threaded ring 309 is larger than the overall outer diameter of the two sets of locking blocks 304 .

[0049] In this embodiment, the threaded ring 309 is rotated to move on the fixing sleeve 302 until the threaded ring 309 moves to one end of the fixing sleeve 302 close to the connecting block 303. Since the inner diameter of the threaded ring 309 is larger than the overall outer diameter of the two sets of locking blocks 304, part of the threaded ring 309 engages with the thread groove of the fixing sleeve 302, and the other part of the threaded ring 309 covers the outside of the locking block 304, thereby blocking and limiting the locking block 304, preventing outsiders from pulling the locking block 304 and causing the locking block 304 to disengage from the locking groove 307 opened in the connecting pipe 2, thereby protecting the locking block 304.

[0050] The working principle and use process of the present invention are as follows: when the solenoid valve with stable connection is used, when two sets of connecting pipes 2 are used to install the solenoid valve body 1, first one end of one set of connecting pipes 2 is inserted into the pipe connection end of the solenoid valve body 1; in this process, the locking block 304 is matched with the locking groove 307 provided in the connecting pipe 2, and the solenoid valve body 1 is squeezed by pushing the connecting pipe 2. At this time, one side of the sealing gasket 301 is blocked by the solenoid valve body 1, so that the connecting pipe 2 squeezes and deforms the sealing gasket 301, which mainly depends on the material of the sealing gasket 301. The elastic deformation of the body fills the gap between the connection part of the solenoid valve body 1 and the connecting pipe 2, thereby preventing fluid leakage and achieving a sealing effect; in this process, the locking block 304 slides on the connecting pipe 2, and the locking block 304 drives the spring 306 to be in a stretched state. At the same time as the sealing gasket 301 is squeezed and deformed, the locking block 304 corresponds to the locking groove 307. Due to the rebound reset of the stretched spring 306, the locking block 304 is driven to slide in the rectangular groove 308 and quickly snap into the locking groove 307 to complete the connection and lock the solenoid valve body 1 and the connecting pipe 2. The lock block 304 is fixed to the locking groove 307 of the connecting pipe 2 through the open rectangular groove 308, thereby improving the locking effect of the card connection. The contraction force of the spring 306 can make the lock block 304 always inserted into the lock groove 307 of the connecting pipe 2, thereby improving the stability of the connection between the solenoid valve body 1 and the connecting pipe 2. The arrangement of the telescopic rod 305 further improves the stability of the connection between the lock block 304 and the connecting block 303, and improves the movement effect of the lock block 304 in the rectangular groove 308 of the connecting block 303. By rotating the threaded ring 309, the lock block 304 can be fixed to the locking groove 307 of the connecting pipe 2. The threaded ring 309 moves on the fixing sleeve 302 until the threaded ring 309 moves to one end of the fixing sleeve 302 close to the connecting block 303. Since the inner diameter of the threaded ring 309 is larger than the overall outer diameter of the two sets of locking blocks 304, part of the threaded ring 309 engages with the thread groove of the fixing sleeve 302, and the other part of the threaded ring 309 covers the outside of the locking block 304, thereby blocking and limiting the locking block 304, preventing outsiders from pulling the locking block 304 and causing the locking block 304 to disengage from the locking groove 307 opened in the connecting pipe 2, thereby protecting the locking block 304.
