Problems solved by technology
[0004] However, the pump structure composed of the above structures has a fixed water outlet pressure value, and does not have the function of self-adjusting water outlet pressure. Therefore, when the required water outlet pressure is different, it must be replaced with a different water outlet pressure. pumps, rather uneconomical
[0005] Furthermore, the source water pressure is not fixed, and when the input source water pressure is high, and the source water flow is pressurized by the pump, excessive water outlet pressure will be generated, which will easily cause the sealing diaphragm to be damaged. And will greatly reduce the accuracy of the output water pressure

Embodiment Construction
[0041] First, see Figure 1 to Figure 3 , The figure shows the first preferred embodiment of the present invention.
[0042] The pump pressure regulating and water cutoff structure provided in this embodiment is mainly composed of a body 1, a coupling member 2 and an outlet pressure regulating group 3, in which:
[0043] The main body 1 is in the shape of a hollow shell. The main body 1 has a water inlet 11 on one side and a water outlet 12 on the other side. The main body 1 has a accommodating portion 13 in the center. There is a water flow space 14 for the water inlet 11 and the water outlet 12 to communicate with each other, the accommodating portion 13 is roughly in the shape of a circular groove, and one side of the accommodating portion 13 is provided with a water outlet hole communicating with the water outlet 12 131. The other side is provided with a source water hole 132 communicating with the water inlet 11, and a water inlet 133 communicating with the water flow space 1...

The invention relates to a pressure-adjusting and water-breaking structure of a pump, which is used for controlling the water outlet pressure of the pump. The structure mainly comprises a body, a connector and a water outlet pressure-adjusting set, wherein the body is a hollow shell, one side of the body is provided with a water inlet, and the other side is provided with a water outlet, a water flow space through which the water inlet is communicated with the water outlet is arranged in the body, a containing part is also arranged in the body; the connector is arranged in the containing part,the connector is provided with a connection hole in the direction facing the containing part of the body, and an adjusting button is arranged in the connection hole and can move vertically in the adjusting button; and the water outlet pressure adjusting set is arranged in the containing part, the water outlet pressure adjusting set comprises an elastic part, a sealing diaphragm and a backstop part, the backstop part corresponds to a water inlet hole, one end of the backstop part, away from the water inlet hole, is connected with the sealing diaphragm, one end of the elastic part presses against the sealing diaphragm, and the other end supports against the adjusting button. The invention has the effects that the structure can control the water outlet pressure of the water flow and can automatically break the water when the water outlet pressure is not enough.
Description
Technical field [0001] The invention relates to a pump, in particular to a pump pressure regulation and water cutoff structure that can control the outlet pressure and can automatically cut off the water when the outlet pressure is insufficient. Background technique [0002] Such as Picture 9 Shown is the structure of the existing pump 8, which mainly has a water inlet 81, a water flow space 82, a water inlet space 83 and a water outlet 84 inside the pump 8, wherein the water flow space 82 and the inlet The water spaces 83 communicate with each other through a water inlet 85, and the water inlet space 83 communicates with the water outlet 84 through a water outlet 86, and a water inlet 85 is provided in the water inlet 85 to receive the water respectively. The space 83 and the water flow space 82 have a sealing diaphragm 87 under hydraulic pressure. One end of the sealing diaphragm 87 is opposite to the water inlet 85 to close the water inlet 85, and the other end of the sealing ...
