Problems solved by technology
[0002] In the process of fluid delivery, it is very important to control the flow rate and hydraulic pressure of the fluid delivery. In the process of controlling the fluid pressure, it is necessary to detect the hydraulic pressure of the fluid to prevent the problem that the fluid hydraulic pressure is too large to cause the pipeline to break or come off; the existing detection There are two methods: one is to install a hydraulic testing instrument on the pipeline, which is the most common testing method, but the existing hydraulic testing instrument is relatively complicated in device structure design, and the cost of the instrument is relatively high; the other One is to add a hydraulic detection function to the solenoid valve, which increases the structural complexity of the solenoid valve. It is difficult to maintain in the subsequent use process and the maintenance cost is high. In addition, once a problem occurs with a certain part of the solenoid valve, it will Affect the use effect of the whole solenoid valve

Embodiment Construction
[0028] The present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-5 shown;
[0029] The inventive point of the present application is that several openings 6 are arranged on the pipe wall of the round pipe, and the several openings are equiangularly distributed on the pipe wall of the round pipe with the center line of the round pipe as the center. The openings are rounded rectangles, so The opening communicates with the inner cavity of the circular tube;
[0030] The invention of the present application is also to install the pressure measuring tube 7 in the round pipe, the port at one end of the pressure measuring tube is close to the port at one end of the round tube, the other end port of the pressure measuring tube is close to the port at the other end of the round tube, and the pressure measuring tube Matched with the inner cavity of the round tube, the side surface of the pressure measuring tube is closely attached to t...

The invention discloses a numerical control valve for detecting fluid hydraulic pressure. The valve comprises a solenoid valve. A water inlet of the electromagnetic valve is connected with a port in one end of a circular pipe through a thread. A port of the other end of the round pipe is connected with a water feeding pipe through threads, a plurality of openings are formed in the pipe wall of theround pipe, the openings are distributed in the pipe wall of the round pipe at equal angles with the center line of the round pipe as the center, the openings are rounded rectangles, and the openingsare communicated with an inner cavity of the round pipe. The valve has the beneficial effects of being simple in structure, high in practicability, low in manufacturing cost and small in maintenancedifficulty.
