Abstract
Description
Technical Field
[0001] This utility model relates to the field of solenoid valve technology, and in particular to a solenoid valve with a spacer. Background Technology
[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. The spacer inside the solenoid valve is an important component, typically located within the valve body cavity, and serves to fix and support other internal components.
[0003] The inventors believe that the following defects often exist: after a long period of use, the diaphragm gasket used to isolate the solenoid valve body is damaged, and it is difficult for the staff to replace the diaphragm gasket, which forces the staff to replace the solenoid valve body, thus wasting resources and increasing the cost of use; therefore, in order to solve the above problems, a solenoid valve with a diaphragm is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult for workers to replace the spacer gasket, forcing them to replace the entire solenoid valve body, thus wasting resources and increasing operating costs. Therefore, this invention proposes a solenoid valve with a spacer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solenoid valve with a spacer, comprising a solenoid valve body, a spacer gasket slidably installed inside the solenoid valve body, a disassembly device provided on the upper surface of the solenoid valve body, the disassembly device comprising two support plates, both of which are fixedly connected to the upper surface of the solenoid valve body, a drive rod threaded into the support plate, one end of the drive rod being rotatably connected to a connecting block, two snap-fit blocks slidably inserted inside the solenoid valve body, the surface of the connecting block being slidably connected to the snap-fit blocks, and the side of the two snap-fit blocks closest to each other being fixedly connected to the spacer gasket, the spacer gasket being made of rubber.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a disassembly device, the spacer gasket can be removed from the solenoid valve body for easy replacement. This avoids the situation where the spacer gasket used to isolate the solenoid valve body is damaged after long-term use, making it difficult for the staff to replace the spacer gasket. This would force the staff to replace the solenoid valve body with a new one, thus wasting resources and increasing the cost of use, and thus improving the service life of the device.
[0007] Preferably, a positioning rod is fixedly connected to the side of the connecting block near the drive rod, and the arc surface of the positioning rod is slidably connected to the support plate.
[0008] The effect achieved by the above components is that the positioning rod restricts the connecting block from rotating with the drive rod, so that the operator can quickly and accurately insert the connecting block into the snap-fit block.
[0009] Preferably, a handle is fixedly connected to the end of the drive rod away from the connecting block, and the surface of the handle is provided with a plurality of anti-slip protrusions.
[0010] The effect achieved by the above-mentioned components is to facilitate operation by staff.
[0011] Preferably, two sealing gaskets are fixedly connected to the surface of the solenoid valve body, and the sealing gaskets are slidably connected to the surface of the snap-fit block.
[0012] The effect achieved by the above components is that the sealing gasket seals the insertion point between the snap-fit block and the solenoid valve body, preventing airflow or liquid flow inside the solenoid valve body from overflowing from the insertion point between the snap-fit block and the solenoid valve body, thus preventing corrosion of the outside of the solenoid valve body.
[0013] Preferably, a pull rope is fixedly connected to the lower surface of the snap-fit block, and a pull ring is fixedly connected to the end of the pull rope away from the snap-fit block.
[0014] The effect achieved by the above components is that the pull rope and pull ring facilitate the operation of the device by the staff.
[0015] Preferably, the surface of the solenoid valve body is provided with a protective device, which includes two square blocks. Both square blocks are fixedly connected to the surface of the solenoid valve body. An L-shaped plate is slidably inserted into the square block. A protective plug is fixedly connected to one side of the L-shaped plate. The arc surface of the protective plug is slidably connected to the solenoid valve body. A fixing rod is fixedly connected to the surface of the square block. An operating plate is slidably connected to the arc surface of the fixing rod. An insertion rod is fixed to one side of the operating plate. An insertion hole is opened on the surface of the L-shaped plate.
[0016] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the connection port of the solenoid valve body is protected from dust, which prevents dust from entering the solenoid valve body through the connection port when it is idle for a long time, resulting in a large amount of dust adhering to the solenoid valve body and reducing the efficiency of the solenoid valve body. This improves the protection of the device.
[0017] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the square block, and the size of the insertion rod is adapted to the size of the insertion hole of the L-shaped plate.
[0018] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.
[0019] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the square block, respectively.
[0020] The effect achieved by the above components is that the first spring improves the stability of the insertion rod when it is limited by the L-shaped plate, thereby improving the stability of the insertion rod when it is limited by the protective plug.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] 1. In this utility model, by setting a disassembly device, the spacer gasket can be easily removed from the solenoid valve body for convenient replacement. This avoids the situation where the spacer gasket used for isolation in the solenoid valve body is damaged after long-term use, making it difficult for the staff to replace the spacer gasket and forcing the staff to replace the solenoid valve body with a new one, thus wasting resources and increasing the cost of use. This improves the service life of the device.
[0023] 2. In this utility model, by setting a protective device, the connection port of the solenoid valve body is protected from dust. This prevents dust from entering the solenoid valve body through the connection port when the valve is idle for a long time, which would cause a large amount of dust to accumulate inside the solenoid valve body and reduce the efficiency of the solenoid valve body. This improves the protective performance of the device. Attached Figure Description

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a solenoid valve with a spacer, including a solenoid valve body 1, a spacer 2 slidably installed inside the solenoid valve body 1, and a disassembly device 3 on the upper surface of the solenoid valve body 1. By setting the disassembly device 3, the spacer 2 can be easily removed from the solenoid valve body 1 for replacement, avoiding the situation where the spacer 2 used for isolation in the solenoid valve body 1 is damaged after long-term use, making it difficult for operators to replace the spacer 2 and forcing them to replace the solenoid valve body 1 with a new one, thus wasting resources and increasing usage costs. This improves the service life of the device. The surface of the solenoid valve body 1 is provided with a protective device 4, which achieves the effect of dust prevention at the connection port of the solenoid valve body 1. This prevents dust from entering the solenoid valve body 1 through the connection port during long-term idle periods, causing a large amount of dust to accumulate inside the solenoid valve body 1, thereby reducing the efficiency of the solenoid valve body 1 and improving the protection of the device.
[0032] The following section will explain the specific design and function of the disassembly device 3 and the protective device 4.
[0033] Reference Figure 3 and Figure 4As shown in this embodiment: the disassembly device 3 includes two support plates 31, both of which are fixedly connected to the upper surface of the solenoid valve body 1. A drive rod 32 is threadedly inserted into the support plate 31, and a connecting block 33 is rotatably connected to one end of the drive rod 32. Two snap-fit blocks 34 are slidably inserted into the solenoid valve body 1, and the surface of the connecting block 33 is slidably connected to the snap-fit blocks 34. The side of the two snap-fit blocks 34 that is close to each other is fixedly connected to the spacer 2, which is made of rubber. A positioning rod 36 is fixedly connected to the side of the connecting block 33 that is close to the drive rod 32. The arc surface of the positioning rod 36 is slidably connected to the support plate 31. When the operator rotates the drive rod 32, the drive rod 32 moves threadedly within the support plate 31, and at the same time, the drive rod 32 drives the connecting block 33 to move. The connecting block 33 drives the positioning rod 36 to slide within the support plate 31. At this time, the positioning rod 36 restricts the connecting block 33 from following the drive rod. The rotation of the drive rod 32 allows the operator to quickly and accurately insert the connecting block 33 into the snap-fit block 34. A handle 35 is fixedly connected to the end of the drive rod 32 away from the connecting block 33. The surface of the handle 35 has several anti-slip protrusions, facilitating operation. Two sealing gaskets 37 are fixedly connected to the surface of the solenoid valve body 1. The sealing gaskets 37 are slidably connected to the surface of the snap-fit block 34, sealing the insertion point between the snap-fit block 34 and the solenoid valve body 1. This prevents airflow or liquid from leaking out from the insertion point of the snap-fit block 34 and the solenoid valve body 1, thus preventing corrosion of the exterior of the solenoid valve body 1. A pull rope 38 is fixedly connected to the lower surface of the snap-fit block 34, and a pull ring 39 is fixedly connected to the end of the pull rope 38 away from the snap-fit block 34. The pull rope 38 and pull ring 39 facilitate operation of the device.
[0034] Reference Figure 5 and Figure 6As shown, specifically, the protective device 4 includes two square blocks 41, both of which are fixedly connected to the surface of the solenoid valve body 1. An L-shaped plate 42 is slidably inserted into the square block 41. A protective plug 43 is fixedly connected to one side of the L-shaped plate 42, and the arc surface of the protective plug 43 is slidably connected to the solenoid valve body 1. A fixing rod 44 is fixedly connected to the surface of the square block 41, and an operating plate 45 is slidably connected to the arc surface of the fixing rod 44. A plug 46 is fixed to one side of the operating plate 45. An insertion hole is opened on the surface of the L-shaped plate 42. A limit plate 47 is fixedly connected to the end of the fixing rod 44 away from the square block 41. The size of the plug 46 is adapted to the size of the insertion hole of the L-shaped plate 42. When the operator pulls the operating plate 45, the operating plate 45 slides on the arc surface of the fixing rod 44. At this time, the limit plate 47 is activated. 7. This design effectively limits the maximum sliding distance of the operating plate 45 on the arc surface of the fixed rod 44, preventing the operating plate 45 from detaching from the arc surface of the fixed rod 44 due to excessive pulling force when the operator pulls it. The arc surface of the fixed rod 44 is fitted with a first spring 48, the two ends of which are fixedly connected to the operating plate 45 and the square block 41, respectively. When the operator releases the operating plate 45, the rebound force of the first spring 48 causes the operating plate 45 to slide on the arc surface of the fixed rod 44. At the same time, the operating plate 45 drives the insertion rod 46 to move until the insertion rod 46 is inserted into the insertion hole of the L-shaped plate 42. At this time, the first spring 48 improves the stability of the insertion rod 46 when it limits the L-shaped plate 42, thereby improving the stability of the insertion rod 46 when it limits the protective plug 43.
[0035] Working principle: When the operator needs to disassemble and replace the spacer gasket 2, they turn the handle 35. The handle 35 drives the drive rod 32 to move threadedly within the support plate 31. Simultaneously, the drive rod 32 drives the connecting block 33 to move. The connecting block 33 drives the positioning rod 36 to slide within the support plate 31 until the connecting block 33 disengages from the locking block 34. At this point, the pull ring 39 is pulled. The pull ring 39 drives the pull rope 38 to move. The pull rope 38 drives the locking block 34 to slide within the solenoid valve body 1. The spacer gasket 2 is deformed under force until the locking block 34 completely disengages from the solenoid valve body 1. Pulling the pull ring 39 causes the pull rope 38 to move, which in turn moves the locking block 34. The locking block 34 then disengages the spacer pad 2 from the solenoid valve body 1. This allows the spacer pad 2 to be easily removed from the solenoid valve body 1 for convenient replacement. This avoids the situation where, after prolonged use, the spacer pad 2, which is used for isolation within the solenoid valve body 1, becomes damaged, making it difficult for operators to replace. This would force operators to replace the entire solenoid valve body 1, resulting in wasted resources and increased operating costs, thus improving the lifespan of the device.
[0036] When the operator needs to dustproof the connection port of the idle solenoid valve body 1, they pull the operating plate 45. The operating plate 45 slides on the arc surface of the fixed rod 44, stretching the first spring 48. At the same time, the operating plate 45 drives the insertion rod 46 to move until the insertion rod 46 no longer obstructs the L-shaped plate 42 from inserting into the square block 41. At this point, the protective plug 43 is pressed, and the protective plug 43 enters the solenoid valve body 1, blocking the connection port of the solenoid valve body 1. At the same time, the protective plug 43 drives the L-shaped plate 42 to insert into the square block 41. Then, the operating plate is released. 45. The rebound force of the first spring 48 causes the operating plate 45 to slide on the arc surface of the fixed rod 44. At the same time, the operating plate 45 drives the insertion rod 46 to move until the insertion rod 46 is inserted into the insertion hole of the L-shaped plate 42. This achieves the effect of preventing dust from entering the solenoid valve body 1 through the connection port when the device is idle for a long time, thus preventing a large amount of dust from adhering to the inside of the solenoid valve body 1 and reducing the efficiency of the solenoid valve body 1. This improves the protection of the device.
