The present invention can also combine at least one of the technical features described in example 2 with example 1 to form a new embodiment.

The working principle is as follows:

the inlet pipe is externally connected with a flow supply device, the valve body is used for guiding flow, and the first through pipe and the second through pipe are externally connected with an auxiliary flow supply device. The first pressure regulating valve is used for regulating and controlling the inflow of the valve body, and the pressure gauge arranged on the inflow pipe is used for measuring the inflow pressure of the valve body. When the flow rate of the guide pipe in the flow inlet pipe is larger than the set value of the first pressure regulating valve, the redundant flow can be guided into the first flow guide shell through the backflow end of the first pressure regulating valve and the first flow guide pipe, so that the pressure inside the first flow guide shell is increased, the flow guide piston is urged to move close to the position direction of the first flow guide pipe, the first flow guide shell and the second flow guide pipe are communicated, and the flow rate in the first flow guide shell can be guided into the flow inlet pipe again. When the flow rate of the guide pipe in the inflow pipe is smaller than the set value of the first pressure regulating valve, no flow is introduced into the first flow guide pipe, external auxiliary flow supply equipment supplies flow into the first flow guide casing through the first flow guide pipe, so that the flow guide piston moves towards the position direction of the first flow guide pipe, air between the flow guide piston and the inner end wall of the first flow guide casing close to the position of the first flow guide pipe is temporarily compressed, at the moment, the first flow guide pipe, the first flow guide casing and the first flow guide pipe are communicated, and the auxiliary flow supply in the inflow pipe is realized. The first one-way diversion valve body and the second one-way diversion valve body are arranged to prevent the first diversion pipe and the second diversion pipe from flowing back.

The second pressure regulating valve is used for regulating and controlling the outlet flow of the valve body, and a pressure gauge arranged on the outlet flow pipe is used for measuring the outlet pressure of the valve body. When the flow rate of the guide pipe in the outflow pipe is larger than the set value of the second pressure regulating valve, the redundant flow can be guided into the second diversion shell through the backflow end of the second pressure regulating valve and the third diversion pipe and then into the third diversion shell through the fourth diversion pipe, and the manual switch valve is closed at the moment. When the guiding amount in the third guide shell is too much, the pressure intensity is increased, and the arranged pressure switch valve can be automatically opened when the pressure intensity in the third guide shell is increased to a certain value, so that the flow in the third guide shell is guided into the outflow pipe again. When the guide flow in the outflow pipe is smaller than the set value of the second pressure regulating valve, the manual switch valve is opened, the flow in the third flow guide shell can be guided into the outflow pipe, and external flow supply equipment can also supply flow to the third flow guide shell through the second through pipe. The third one-way flow guide valve body, the fourth one-way flow guide valve body, the fifth one-way flow guide valve body, the sixth one-way flow guide valve body and the through one-way valve body are respectively used for preventing the third flow guide pipe, the fourth flow guide pipe, the fifth flow guide pipe, the sixth flow guide pipe and the second through flow guide pipe from flowing back.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
