Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a signal gate valve. Background Technology

[0002] Gate valves are common valves used to control fluid passages. They operate by opening or closing a gate perpendicular to the fluid flow direction. With the development of industrial automation, more and more industrial processes require electronic or electrical signals to regulate valve operation, rather than relying solely on manual control. Therefore, a signal gate valve needs to be designed.

[0003] Most existing gate valves are simple devices that allow water to flow by opening and closing the valve. They lack the function of remote control and limiting the flow rate and speed of the valve. The opening and closing tasks need to be performed manually. Therefore, it is necessary to install a remote control device to realize remote control of opening and closing and detection. In addition, existing gate valves lack the function of filtering the external liquid flowing through them when opening and closing to prevent impurities from flowing into the pipe and causing blockage of the external pipe, thus reducing the flow rate.

[0004] A signal gate valve disclosed in CN219317753U includes a housing. An electric telescopic rod and a fixed box are fixedly installed on the top of the housing. A movable box is fixedly installed at one end of the output shaft of the electric telescopic rod, and a lifting rod is slidably connected to one side of the movable box. The advantages of this invention are: through the cooperation of the electric telescopic rod, movable box, lifting rod, button block, intelligent control center, photoelectric sensor, photoelectric induction plate, and top block, in emergency situations, personnel can operate the electric telescopic rod to move the movable box via a mobile phone connected to the intelligent control center from a certain distance from the valve. This allows the button block to press the button, enabling the valve to operate accordingly, thus making the process faster and more time-saving. Furthermore, through the cooperation of the battery, mounting plate, and solar panel, solar energy is collected and stored for use, making it more green and environmentally friendly.

[0005] While the aforementioned patent achieves the goal of collecting and storing solar energy through the cooperation of the battery, mounting plate, and solar panel, making it more green and environmentally friendly, the device lacks the ability to detect the flow rate and speed of the external flow inside the tube while controlling the opening and closing of the flow, and to remotely control it at the same time to prevent the need for excessive manual operation. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The purpose of this utility model is to provide a signal gate valve to solve the problems mentioned in the background art. Most existing gate valves are simple devices that restrict water flow by opening and closing the valve. They lack the function of remote control and limiting the flow rate of the valve. They require manual operation to open and close the valve. Therefore, it is necessary to install a remote control device to realize remote control of opening and closing and detection. In addition, existing gate valves lack the function of filtering the external liquid flowing through when opening and closing the valve to prevent impurities from flowing into the pipe and causing blockage of the external pipe, thus reducing the flow rate.

[0010] As a further embodiment of this utility model, the top of the movable cable tie is fitted with an adjusting buckle, and the left end of the adjusting buckle is fitted with a strap. The strap serves to fix the flow sensor.

[0011] As a further embodiment of this utility model, the left side of the adjusting buckle is fixedly connected with a buckle tooth, and the outer buckle tooth is connected with a buckle hole. The buckle hole is installed on the surface of the strap, and the buckle tooth serves to fix the tightness and length of the strap.

[0012] As a further embodiment of this utility model, a tube cap is fixedly connected to the top of the filter tube, and a handle ring is fixedly connected to the top surface of the tube cap. The tube cap serves to seal and prevent leakage.

[0013] As a further embodiment of this utility model, a sealing ring is installed inside the tube cover, and the inner side of the sealing ring is slidably connected to the outside of the filter tube. The sealing ring serves to reinforce and seal the interior.

[0014] As a further embodiment of this utility model, fixing blocks are fixedly connected to the left and right sides of the tube cover, and fixing holes are opened inside the fixing blocks. The fixing blocks serve to close the tube cover and the filter tube.

[0016] (III) Beneficial Effects

[0017] This utility model provides a signal gate valve, which has the following beneficial effects:

[0018] 1. This signal gate valve, through the setting of the flow limiting mechanism, is installed in the middle of the external pipeline when the gate valve is working. A connecting column is installed on the right side of the gate valve, and the connecting column connects to the PLC controller on the right side of the gate valve. The PLC controller remotely controls the opening and closing of the gate valve to block or allow the flow of external liquid. A flow sensor that can detect the flow rate and speed of the liquid flowing inside and outside the pipe is installed on the outside of the right side of the gate valve. The flow sensor is fixed to the outside of the gate valve by fastening the adjusting buckle and buckle teeth inside the movable cable tie and fastening the buckle hole on the surface of the cable tie. This achieves the function of remote control and limiting the flow rate and speed of the valve, avoiding the need for manual operation of the opening and closing task due to the lack of controller function.

[0019] 2. This signal gate valve, through the setting of the filtering mechanism, opens when the gate valve is working, allowing external liquid to flow in. It passes through the water inlet pipe on the left side of the gate valve, and a filter branch pipe is installed inside the water inlet pipe. The filter branch pipe is equipped with a filter tube. Since the filter tube is equipped with a filter screen, it can filter out impurities mixed in with the external liquid. This plays a role in filtering the external liquid flowing through, preventing impurities from flowing directly into the pipe and causing blockage of the external pipe, thus reducing the flow rate.
