Description

Technical Field

[0001] This utility model relates to a gas motor valve, specifically a pipeline-type intelligent valve with pressure monitoring. Background Technology

[0002] A gas-powered electric valve, also known as a gas quick-closing valve, is a valve body controlled by a motor to open and close, controlling the flow rate of the medium in the pipeline through its open and closed states. Some existing gas-powered electric valves, to ensure isolation between the motor and the valve body, use a combination of a motor and corresponding gears to drive a screw or lead screw to move up and down, which in turn moves the valve seal of the screw or lead screw to achieve opening and closing. For example, Chinese patent document CN221034009U, authorized on May 28, 2024, entitled "Gas Electric Screw Valve," describes this type of valve. The top multi-combination control box of this gas electric screw valve contains a battery, circuit board, switch button, and manual cover. However, battery replacement is inconvenient, the overall disassembly and assembly of the multi-combination control box is inconvenient, and it lacks a location for installing and using temperature and pressure sensors. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a pipeline-type intelligent valve with pressure monitoring, thereby solving the technical problems of existing similar products lacking a location for temperature and pressure sensors for installation and use, and the inconvenience of disassembling and assembling the control box, which leads to inconvenience in battery replacement. This objective is achieved through the following technical solution.

[0004] A pipeline-type intelligent valve with pressure monitoring is disclosed. The valve body has an inlet and an outlet on both sides of its bottom. A valve cover is located at the top of the valve body between the inlet and outlet. A sealing plate and a valve core assembly are located at the outlet passage within the valve body below the valve cover. The sealing element at the valve core of the valve core assembly is driven by a motor shaft and gear assembly to close or open the outlet passage within the valve body. A key structural design feature is that an inlet temperature and pressure sensor and an outlet temperature and pressure sensor are located on one side of the top of the valve cover. The probes of these sensors extend into the inlet and outlet passages within the valve body, respectively. These sensors are connected to a PCB circuit board inside the cover at the top of the valve cover via wiring. These temperature and pressure sensors monitor parameters such as the flow rate, pressure, and temperature of the gas within the valve body, facilitating valve closure and sealing in cases of overpressure or overtemperature in the pipeline.

[0005] The valve core assembly includes a pressure plate, a seal, a valve core, a bracket, a motor base, a screw, a gear assembly, a motor gear, a motor, and a motor cover. One end of the valve core is connected to the seal, and a pressure plate is provided at the bottom ring diameter of the seal above the sealing plate. The other end of the valve core is connected to one end of the screw, and the other end of the screw is connected to the gear assembly through an output gear. The motor gear at the motor shaft meshes with the drive gear of the gear assembly. The motor, gear assembly, motor gear, output gear, and drive gear are arranged in the cavity formed by the motor base and the motor cover. The motor base is fixedly installed on the top of the bracket, and the support feet at the bottom of the bracket are fixedly installed outside the air outlet of the valve body.

[0006] One end of the screw extends out and aligns with the lower through hole of the upper motor cover. The valve cover above the lower through hole of the motor cover has an upper through hole that is aligned with it. A manual rod is inserted into the upper through hole of the valve cover. A sealing ring is provided on the outer diameter of the manual rod in the upper through hole. A spring is provided on the outer diameter of the manual rod. A cover plate is provided above the upper through hole of the valve cover. When the manual rod extends out of the cover plate hole, the protruding ring diameter of the manual rod abuts against and is limited to the cover plate hole. The two ends of the spring abut against the ring diameter of the manual rod and the outer side of the upper through hole, respectively. An aligned battery cover is provided on the top of the cover above the manual rod. The battery cover is fixed to the cover by screws. A controller cavity is provided on one side of the cover below the battery cover. The controller cavity of the cover contains a battery and a PCB circuit board. The PCB circuit board is connected to the motor through wiring. The PCB circuit board has a wireless Bluetooth module.

[0007] The controller cavity of the cover protrudes outward, the battery cover is eccentrically located on one side of the top of the cover, and a transparent window is provided on the other side of the top of the cover.

[0008] The motor is eccentrically positioned on one side of the inner cavity of the motor base and motor cover.

[0009] This utility model has a reasonable structural design, is easy to use, disassemble, and replace, and has good sealing and stability. In particular, the controller, temperature and pressure sensor, and battery are easy to disassemble and replace. It is suitable for use as a pipeline-type intelligent valve with pressure monitoring, as well as for structural improvements of similar products. Attached Figure Description
