Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a multi-piston hydraulic solenoid valve. Background Technique

[0002] The piston-type hydraulic solenoid valve is a fluid control element that relies on an electromagnetic coil to generate electromagnetic force to drive the opening and closing of the valve. It is one of the commonly used actuators in the pipeline control process. When powered on, the electromagnetic coil generates electromagnetic force, directly attracting the valve core and causing the valve core to displace. When powered off, the electromagnetic force disappears, and the valve core returns to its original position by the spring. The piston-type solenoid valve mainly includes a base and a solenoid valve body. The base is an important component of the solenoid valve. The base not only provides stable support for the hydraulic solenoid valve but also ensures the sealing and stability of the solenoid valve, thus guaranteeing its normal operation and the reliability of long-term use.

[0026] The following further describes the present invention in conjunction with embodiments.

[0027] Embodiment 1

[0028] Such as Figures 1-3As shown in the figure, a multi-piston hydraulic solenoid valve, the inlet pipe assembly 2 further includes a clamping plate 24 slidably connected to the inside of the installation cavity 21, and there are two groups of clamping plates 24.

[0029] Embodiment 2

[0030] As Figure 1 and Figures 4-5 As shown in the figure, a multi-piston hydraulic solenoid valve, the reinforcement assembly 5 further includes a cylinder 53 fixedly connected to one side of the connecting plate 51, and there is a grip plate 52 on one side of the cylinder 53. On one side of the grip plate 52, there is a connecting rod 56 fixedly connected, and one end of the connecting rod 56 extends into the cylinder 53, and the connecting rod 56 is slidably connected to the cylinder 53. One end of the connecting rod 56 away from the grip plate 52 is fixedly connected with a plugging rod 54, and one end of the plugging rod 54 passes through the cylinder 53 and extends to the outside thereof. The plugging rod 54 is slidably connected to the cylinder 53. The plugging rod 54 is matched with the empty slot provided in the middle of the support hole plate 55.

[0031] In summary, the working principle of the device of the present utility model: The present utility model discloses a multi-piston hydraulic solenoid valve. After the piston-type hydraulic solenoid valve is energized, the electromagnetic force directly opens the pilot hole, and the main valve piston is successively lifted upward, and the valve opens; when the inlet and the outlet reach the starting pressure difference, after being energized, the electromagnetic force first opens the pilot hole, and the pressure in the upper chamber of the main valve piston decreases, so that the differential pressure and the electromagnetic force are used to pull the main piston, and the valve port opens; when powered off, the pilot hole is closed by spring reset, the pressure in the upper chamber of the main piston increases, and the main piston is pushed downward to close the valve; in order to increase the stability when the solenoid valve assembly 1 is installed with the external pipeline, a fixing mechanism is installed on the inlet pipe assembly 2 and the outlet pipe assembly 3. The feeding and discharging external pipelines are respectively butted with the inlet pipe assembly 2 and the outlet pipe assembly 3, and the external pipeline is completely inserted and clamped into the inner cavity of the inlet pipe assembly 2. At this time, the two clamping plates 24 are located on the upper and lower sides of the inlet pipe assembly 2. Rotate the knob 22, and at the same time the first screw rod 23 rotates. The first screw rod 23 drives the two first connecting blocks 26 to move closer to each other. At the same time, the two second connecting blocks 27 move closer to each other along the limiting rod 28. At this time, the two clamping plates 24 move closer to each other until the two clamping plates 24 tightly clamp the upper and lower sides of the external pipeline, and the rubber sealing pad 25 is closely attached to the pipeline, increasing the stable performance of the clamping of the clamping plate 24. The outlet pipe assembly 3 and the external pipeline are installed and connected in the same way. Through this operation device, the effect of being able to fix the external connection pipe more firmly is achieved; when it is necessary to detach the solenoid valve assembly 1 from the external pipeline, rotate the knob 22 in the reverse direction, so that the first screw rod 23 rotates in the reverse direction. The first screw rod 23 drives the two clamping plates 24 to move in the opposite direction until the two clamping plates 24 are both away from the external pipeline, and then the external pipeline is detached from the inlet pipe assembly 2 and the outlet pipe assembly 3. The fixing mechanism installed in this valve body is convenient to operate, facilitating the user to install and detach the device from the external pipeline. This setting can increase the installation stability of the multi-piston hydraulic solenoid valve and the external pipeline, avoiding the problem of unstable connection of the device resulting in material leakage, and improving the use effect of the device;

[0032] The base is an important component of the solenoid valve. The base not only provides stable support for the hydraulic solenoid valve but also ensures the stability of the solenoid valve. In the traditional hydraulic solenoid valve, a screw - fixed connection method is used between the valve body and the base. When a fault occurs in the valve body, it is not easy to perform maintenance operations on it, which greatly affects the use effect. Place the first magnet plate 11 on the top surface of the second magnet plate 12. The first magnet plate 11 and the second magnet plate 12 are magnetically fixedly connected. At this time, the cavity cylinder 53 is above the support hole plate 55. Press down the two grip plates 52. The grip plates 52 drive the connecting rod 56 and the insertion rod 54 to move downward until the insertion rod 54 is inserted through the central hole slot of the support hole plate 55. The insertion rod 54 and the support hole plate 55 are installed in a plug - in and fixed manner. By strengthening the two sides of the solenoid valve assembly 1 respectively, the solenoid valve assembly 1 is stably installed on the top of the base assembly 4. When it is necessary to detach the solenoid valve assembly 1 from the base assembly 4, pull the two grip plates 52 upward simultaneously. The grip plates 52 drive the connecting rod 56 and the insertion rod 54 to pull upward. The insertion rod 54 rises and slides back into the cavity cylinder 53. At the same time, the insertion rod 54 is completely withdrawn from the support hole plate 55, and the insertion rod 54 is completely detached from the support hole plate 55. Pull the solenoid valve assembly 1 upward until the first magnet plate 11 and the second magnet plate 12 are completely separated. Then, the solenoid valve assembly 1 can be detached from the base assembly 4, which is convenient for users to repair and maintain the solenoid valve assembly 1. This setting realizes the function of being able to more conveniently remove the solenoid valve assembly 1 from the base assembly 4, improves the use effect. Through the installation method of the two reinforcing components 5, it avoids the screw - fixed connection method between the valve body and the base. When a fault occurs in the solenoid valve assembly 1, it is easy to perform maintenance operations on it, and the use effect of the device is improved.

[0033] The above - mentioned embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the present utility model is within the protection scope of the present utility model.
