Detailed Description

Referring to fig. 1, the integrated structure of the intelligent fluid control system of the present invention includes a control tank 8 as a main body and a pressure sensor 6. The control tank 8 is the pressure tank of the system, and the control tank 8 is composed of a cylindrical tank body 2 with an opening at the front part and a front cover 1 buckled on the tank body 2. The center of the front cover 1 is provided with a water inlet joint A, and the water inlet joint A is provided with threads. In the tank body 2, the front part is provided with an elastic bag 3, the elastic bag 3 is in a round cap shape, and the rear part is provided with an inner hole opposite to the water inlet joint A. The periphery of the elastic bag 3 is tightly attached to the inner wall of the tank body 2, the front part of the elastic bag is outward formed at the opening of the tank body 2 to form a hem, the hem is matched with a groove on the periphery of the front cover 1 and clamped in the groove to seal the opening of the tank body 2, and the elastic bag 3 is extruded between the front cover 1 and the tank body 2. The elastic bag 3 is made of soft elastic material, which is generally rubber, but not limited to rubber. Behind the elastic bag 3 is a metal support 4 which is seamlessly opposed to the elastic bag 3. The metal bracket 4 is also provided with an inner hole matched with the inner hole of the elastic bag 3. In the tank body 2, a spring 5 is sleeved outside the metal support 4, the top end of the spring 5 is tightly propped against the metal support 4, and the tail end of the spring is tightly propped against a bottom plate at the rearmost side of the tank body 2. In order to stably limit the spring 5, a cylindrical limiting convex seat 7 is arranged on the bottom plate of the tank body 2, and the tail end of the spring 5 is sleeved on and fixed on the limiting convex seat 7. The pressure sensor 6 is tightly clamped in the metal bracket 4, and a sensor pressure taking hole 6.1 at the front end of the pressure sensor 6 is positioned in an inner hole of the metal bracket 4 and can detect the pressure on the control tank 8. The pressure sensor 6 is provided with an information wire 6.2, a wire outlet hole is arranged in the limiting boss 7 on the bottom plate of the tank body 2, and the information wire 6.2 is communicated to the outside through the wire outlet hole and is connected to an external control system.

Referring to fig. 2, in the system, the front end of the control tank 8 and the pump body 9 are fitted together, receiving the pressure of the pump body 9. Compared with the existing structure mode, the structure mode of the invention has the advantage that the pressure sensor 6 is in a more stable working state.

The working process of the invention is as follows:

fluid enters the interior region of the elastic bag 3 through the water inlet hole a in the front cover 1 and fills this space, expanding the elastic bag 3 and pushing the metal bracket 4 to move backward. At this moment, the spring 5 is compressed to generate corresponding elastic force to play a role of buffering fluid, meanwhile, the fluid inside the elastic bag 3 enters the pressure sensor 6 through the sensor pressure taking hole 6.1 at the front end of the pressure sensor 6, relatively stable pressure of the fluid at this moment is collected by combining the buffering of the spring 5, pressure information is transmitted through the information line 6.2, and finally the purpose of accurately controlling the pump by the control system is achieved.
