Solenoid valve with flow detection mechanism

Abstract

This utility model discloses an electromagnetic valve with a flow detection mechanism, relating to the field of electromagnetic valve technology. It includes a fluid passage pipe on which an electromagnetic component is fixedly installed. The electromagnetic component contains a valve core, and a plug is fixedly installed at the lower end of the valve core. A sealing gas film is provided inside the fluid passage pipe. An inlet is located at the right end of the fluid passage pipe, and an outlet is located at the left end. In this invention, a rotating mechanism consisting of a rod, a fixed block, a bearing, a connecting rod, and an impeller is installed at the lower end of the plug. This mechanism, in conjunction with a speed sensor with a sensing rod installed on the fluid passage pipe, causes the impeller to rotate when the fluid flows through the connecting slot. The speed of the impeller is transmitted to the speed sensor through the contact between the connecting rod and the sensing rod. Thus, while realizing the on / off control function of the electromagnetic valve, flow detection is simultaneously completed. This integrates the electromagnetic valve and the flow detection mechanism into one unit, eliminating the need for a separate flow detection device.

Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to an electromagnetic valve with a flow detection mechanism. Background Technology

[0002] Several companies using solenoid valves have reported that in existing technologies, the solenoid valve and the flow detection mechanism are separate. If both fluid on / off control and flow detection are required, an additional flow detection device must be installed, which not only increases the complexity of the overall structure but also occupies more installation space and increases equipment costs.

[0003] When the two are set up separately, the timeliness and accuracy of flow detection are easily affected. Moreover, during installation and commissioning, the solenoid valve and flow detection mechanism need to be operated separately, which increases the complexity of the process. Some companies omit the flow detection step in order to reduce costs, which leads to the inability to grasp the fluid flow status in a timely manner, causing production failures or product quality problems. Many of the related feedback received are related to poor cooperation between the solenoid valve and the flow detection mechanism, which is particularly prominent in production scenarios with high requirements for flow accuracy. These pain points in practical applications have prompted the development of a solenoid valve that integrates a flow detection mechanism. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a solenoid valve with a flow detection mechanism, solving the technical problem that in existing technologies, the solenoid valve and the flow detection mechanism are separate. If fluid on / off control and flow detection are required to be achieved simultaneously, an additional flow detection device is needed, which not only increases the complexity of the overall structure but also occupies more installation space and increases equipment costs.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A solenoid valve with a flow detection mechanism includes a fluid passage pipe, an electromagnetic component fixedly mounted on the fluid passage pipe, a valve core inside the electromagnetic component, a plug fixedly mounted at the lower end of the valve core, a sealing gas film inside the fluid passage pipe, an inlet at the right end of the fluid passage pipe, an outlet at the left end of the fluid passage pipe, a connecting groove inside the fluid passage pipe for connecting the inlet and the outlet, the plug being placed in the connecting groove of the fluid passage pipe, and a rotating mechanism for measuring the flow rate at the lower end of the plug.

[0009] Preferably, the rotating mechanism includes a lifting rod, which is fixedly installed at the lower end of the plug, and a fixing block is fixedly installed at the lower end of the lifting rod, and a bearing is fixedly installed on the fixing block.

[0010] Preferably, a connecting rod is fixedly installed on the bearing, the connecting rod is rotatably connected to the fixed circular block through the bearing, an impeller is fixedly installed on the left end of the connecting rod, the impeller is set in the communicating slot of the fluid pipe, and a connector is provided on the right end of the connecting rod.

[0013] In this new invention, a rotating mechanism consisting of a hanger, a fixed block, a bearing, a connecting rod, and an impeller is installed at the lower end of the plug. This mechanism, in conjunction with a speed sensor with a sensing rod installed on the fluid flow pipe, causes the impeller to rotate as the fluid flows through the connecting slot.

This allows for simultaneous flow detection while simultaneously controlling the on / off state of the solenoid valve. By integrating the solenoid valve and the flow detection mechanism into one unit, a separate flow detection device is eliminated, simplifying the structure, saving installation space and cost, and improving ease of use and integration.

[0021] This application provides a solenoid valve with a flow detection mechanism, which effectively solves the technical problem in the prior art where the solenoid valve and the flow detection mechanism are separated. If fluid on / off control and flow detection are required to be realized simultaneously, an additional flow detection device is needed, which not only increases the complexity of the overall structure but also occupies more installation space and increases the cost of the equipment.

[0022] Example

[0023] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment aims to effectively solve the technical problem that in the prior art, the solenoid valve and the flow detection mechanism are separated. If fluid on / off control and flow detection are required to be realized simultaneously, an additional flow detection device is needed, which not only increases the complexity of the overall structure but also occupies more installation space and increases equipment costs. The overall approach is as follows:

[0024] To address the problems existing in the prior art, this utility model provides a solenoid valve with a flow detection mechanism, including a fluid passage pipe 8. An electromagnetic component 13 is fixedly installed on the fluid passage pipe 8 by four bolts. A valve core 12 is provided inside the electromagnetic component 13, and a plug 6 is fixedly installed at the lower end of the valve core 12. When the electromagnetic component 13 is energized, it controls the valve core 12 and the plug 6 to move up and down inside, thereby realizing the opening and closing. A sealing gas membrane 11 is provided inside the fluid passage pipe 8. The sealing gas membrane 11 is made of soft rubber and is fixedly installed with the electromagnetic component 13, which plays a role in sealing the inside of the electromagnetic component 13.

[0025] The fluid passage 8 has an inlet 14 on the right side and an outlet 15 on the left side. The fluid passage 8 has a connecting slot 10 inside, which is used to connect the inlet 14 and the outlet 15. The plug 6 is placed in the connecting slot 10 of the fluid passage 8. The lower end of the plug 6 is provided with a rotating mechanism for measuring the flow rate.

[0026] like Figure 4 and Figure 5As shown, the rotating mechanism includes a lifting rod 5, which is fixedly installed at the lower end of the plug 6. A fixed circular block 4 is fixedly installed at the lower end of the lifting rod 5. A bearing 2 is fixedly installed on the fixed circular block 4. A connecting rod 1 is fixedly installed on the bearing 2. The connecting rod 1 is rotatably connected to the fixed circular block 4 through the bearing 2. An impeller 3 is fixedly installed at the left end of the connecting rod 1. The impeller 3 is located in the connecting slot 10 opened in the fluid pipe 8. A connector is provided at the right end of the connecting rod 1. When the rotating mechanism is used to measure the flow rate, the valve core 12 is controlled to move upward by the electromagnetic component 13. After the valve core 12 moves upward, the plug 6 moves upward accordingly. At this time, the inlet 14 and outlet 15 of the fluid pipe 8 are connected through the connecting slot 10. The liquid entering from the inlet 14 will pass through the connecting slot 10 and enter the outlet 15. When passing through the connecting slot 10, it drives the impeller 3 to rotate.

[0027] A speed sensor 7 is fixedly installed on the fluid passage pipe 8. The speed sensor 7 is equipped with a sensing rod 9, which is installed through the inside of the fluid passage pipe 8. When the electromagnetic component 13 is energized, the valve core 12 and the plug 6 move upward. At this time, the plug 6 drives the fixed block 4 and the connecting rod 1 to move upward, and the impeller 3 will also continue to move upward. At this time, the connector at the right end of the connecting rod 1 will contact the sensing rod 9, thereby transmitting the speed of the impeller 3 to the speed sensor 7. Then, through other electronic mechanisms, the liquid flow rate can be measured.

[0028] Working principle:

[0029] First, when the electromagnetic component 13 is not energized, the valve core 12 is in a downward state under the action of the reset mechanism, which drives the plug 6 to fit tightly into the connecting slot 10 of the fluid pipe 8. At this time, the channel between the inlet 14 and the outlet 15 is blocked, and the fluid cannot flow.

[0030] When the electromagnetic component 13 is energized, it generates an electromagnetic force that drives the valve core 12 to move upward. The plug 6 moves upward synchronously with the valve core 12 and disengages from the connecting slot 10, allowing the inlet 14 and outlet 15 to be connected through the connecting slot 10. Fluid can then flow in from the inlet 14 and through the connecting slot 10 to the outlet 15.

[0031] In the second step, as the plug 6 moves upward, the fixed circular block 4, bearing 2 and connecting rod 1 move upward as a whole through the fixed hanging rod 5 at the lower end, so that the connector on the right side of the connecting rod 1 contacts the sensing rod 9 of the speed sensor 7.

[0032] When the fluid flows through the connecting slot 10, it impacts the impeller 3 located in the slot, pushing the impeller 3 to rotate around the bearing 2 (because the connecting rod 1 and the fixed round block 4 are rotatably connected through the bearing 2, the rotation of the impeller 3 can drive the connecting rod 1 to rotate synchronously).

[0033] The rotational speed of impeller 3 is transmitted to the connector through connecting rod 1, and then fed back to speed sensor 7 by contacting sensing rod 9. Speed ​​sensor 7 converts the rotational speed signal into an electrical signal. Combined with the characteristic parameters of impeller 3 (such as the number and size of blades), the real-time flow rate of the fluid can be calculated by an external electronic computing mechanism.

[0034] Third, the sealing gas membrane 11 (made of soft rubber) inside the fluid conduit 8 is fixedly connected to the electromagnetic component 13, which can effectively prevent fluid from entering the electromagnetic component 13 and ensure the stable operation and service life of the electromagnetic control mechanism.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
