Description

Multidimensional pressure detection motor valve Technical Field The utility model relates to the technical field of valves, in particular to a multidimensional pressure detection motor valve. Background The motor valve is a valve installed and used on a natural gas pipeline and mainly comprises a valve body, a motor, a sealing element, a sensor and the like. The conventional motor valve detection unit is only arranged in the air outlet bin, and only one pressure detection unit, namely only one pressure sensor, can only detect the pressure of the air outlet bin and cannot detect the pressure of the air inlet bin, and the flow detection unit is not provided, so that the flow cannot be detected, and when the flow in the pipeline is abnormal (such as pipe disconnection, pipeline damage, pipeline joint air leakage and the like), the flow cannot be monitored, and therefore safety accidents can be caused. In addition, the pressure detection unit of the conventional motor valve is directly exposed in the pipeline, impurities, greasy dirt and the like in the pipeline can be directly attached to the surface of the sensor, and the service life is short. Disclosure of Invention The utility model aims to provide a multidimensional pressure detection motor valve so as to solve the problems. In order to achieve the purpose, the technical scheme is that the multidimensional pressure detection motor valve comprises a valve body, a motor, a sensor and a sealing piece, wherein the valve body comprises an air inlet bin, an air outlet bin, a sensor shell, the sensor is arranged below the valve body, through holes are respectively formed in positions, corresponding to the air inlet bin and the air outlet bin, of the sensor shell, the air inlet bin and the air outlet bin are respectively communicated with the through holes, a diaphragm and a valve clack are arranged above the valve body, a main shaft is connected to the valve clack, a circuit board is arranged above the main shaft, the upper end of the main shaft is connected with a handle, the motor is located on one side of the main shaft, the multidimensional pressure detection motor valve further comprises an upper shell, the motor, the circuit board and the valve clack are all located in the upper shell, the main shaft extends out of the upper shell, and the handle is located on the outer side of the upper end of the upper shell. According to the utility model, the sensor shell is arranged and sealed with the valve body through an O-shaped ring, preferably, the lower end of the sensor shell is provided with a cover plate, the cover plate is connected with the valve body through screws, the sensor shell is tightly pressed, the sensor circuit board is arranged below the shell and fastened through a sealing ring and threads, and preferably, the sensor circuit board is encapsulated into an integrated structure, thus the sensor shell is fixed, and the sensor shell has good tightness, high stability and long service life; In addition, the two through holes of the sensor shell are respectively communicated with the air inlet bin and the air outlet bin of the valve body, so that the pressure and other conditions of the air outlet bin and the air inlet bin can be detected simultaneously, a handle is also arranged, and when the circuit board receives a valve closing signal, the handle can control the motor to rotate, and the motor is driven to a main shaft through a gear to rotate, so that the valve clack is driven to move upwards or downwards, and the valve is controlled to be opened and closed. The handle can rotate when the main shaft rotates, so that whether the motor runs or not can be observed, and the main shaft can be controlled to rotate by rotating the handle, so that the valve clack is driven to control the valve to be opened and closed. As a preferable technical scheme, the sensor is internally provided with a pressure detection unit, a flow detection unit and a temperature detection unit. The multi-dimensional detection of parameters such as pressure, flow, temperature and the like can be realized simultaneously, so that the safety of the pipeline is ensured, and the occurrence of safety accidents is effectively avoided. For example, when the flow in the pipeline is abnormal (such as pipe removal, pipeline damage, pipeline joint air leakage and the like), the valve can be closed through the motor, and the air source is cut off, so that the occurrence of safety accidents is effectively avoided. As an optimal technical scheme, the valve clack is connected with the main shaft through a threaded screw rod. As an optimal technical scheme, the upper end of the valve clack is provided with a limiting groove. The valve clack can be fixed and does not rotate in the vertical displacement process, the precision is higher, and the sealing effect is better.
