Detailed Description
The application is described in further detail below with reference to fig. 1-3.
Referring to fig. 1 and 2, an embodiment of the present application discloses a water pump pressure controller including a middle body 1, a pressure membrane assembly 2, and a flow float assembly 3.
The middle body 1 is provided with an inlet 11, a mounting cavity 12 and an outlet 13 which are communicated with each other. The inlet 11 is used for connecting with the water outlet of the water supply pump, and the outlet 13 is used for connecting with a water outlet valve (such as a tap).
The pressure membrane assembly 2 is disposed within the mounting cavity 12. The middle body 1 is connected with a reed switch for pressure detection corresponding to the pressure membrane module 2. When the water pump works and the water outlet valve is closed, the water pressure in the middle body 1 (in the installation cavity 12) rises, the pressure membrane component 2 acts under the action of the water pressure, and the magnet in the pressure membrane component 2 is far away from the reed pipe for pressure detection, so that the water pressure in the middle body 1 is detected to rise, and the water pump is controlled to be closed.

Under the condition that the water pump does not work and the water outlet valve is opened, water in the installation cavity 12 is output from the outlet 13, water flow pushes the flow float assembly 3 to act, and a magnet arranged in the flow float assembly 3 is far away from the reed pipe for flow detection, so that flow detection is realized, and the water pump is controlled to be opened.

Referring to fig. 2, the water pump pressure controller further includes a return spring 4 and an adjustment assembly 5.
A return spring 4 is connected between the central body 1 and the flow float assembly 3, the return spring 4 causing the flow float assembly 3 to have a tendency to contact the contact surface 14. Under the condition that the water outlet valve is closed, the elastic force of the reset spring 4 drives the flow floater assembly 3 to move and approach the contact surface 14, so that the reed switch for flow detection is conducted.
Referring to fig. 3, the adjustment assembly 5 is in contact with the flow float assembly 3, and the frictional force f between the adjustment assembly 5 and the flow float assembly 3 increases as the angle α between the direction of movement of the flow float assembly 3 and the vertical increases.
The adjustment assembly 5 includes a drum 51 and a lock 52.
The drum 51 is disposed coaxially with the outlet 13, and the drum 51 communicates with the outlet 13. The drum 51 is rotatably connected to the central body 1 about its own axis. The locking member 52 is used to fix the relative position of the drum 51 and the central body 1. The locking element 52 includes an integrally formed threaded sleeve 521 and locking collar 522. A lock ring 522 is located at the inner periphery of the screw sleeve 521 for screwing to the outlet 13 of the central body 1. The drum 51 includes an integrally formed barrel 511 and a snap ring 512. Barrel 511 is coaxially rotatably mounted within lock ring 522 with snap ring 512 on the side of lock ring 522 facing center body 1.
Tightening the screw sleeve 521 clamps the lock ring 522 together with the intermediate body 1 (end face of the outlet 13) to fix the relative positions of the drum 51 and the intermediate body 1 by friction.
The adjustment assembly 5 further comprises a sleeve 53, a weight 54, a friction plate 55 and an adjustment spring 56.
The sleeve 53 is coaxially rotatably coupled within the bowl 51, with the sleeve 53 having an inner diameter greater than the inner diameter of the outlet 13. The weight 54 is fixedly attached to the sleeve 53 such that the center of mass of the weight 54 and the sleeve 53 as a whole is offset from the axis of the sleeve 53.

The friction plate 55 has a fan-shaped ring shape in the axial projection of the sleeve 53, and the inner diameter of the friction plate 55 is slightly larger than the inner diameter of the outlet 13. The end of the flow float assembly 3 remote from the abutment surface 14 is slidably inserted into the sleeve 53 and there is at least one friction plate 55 that is not in contact with the flow float assembly 3.
The friction factors between the different friction plates 55 and the flow float assembly 3 are different. Perpendicular a coincides with the centroid of weight 54 and sleeve 53, perpendicular a being perpendicular to the axis of sleeve 53. The straight line B, the vertical line a, and the axis of the sleeve 53 intersect perpendicularly in pairs at a point. The friction plate 55 intersecting line B has the greatest friction factor with the flow float assembly 3.
An adjusting spring 56 is connected between the drum 51 and the sleeve 53, and the adjusting spring 56 causes the sleeve 53 to have a tendency to rotate to the level of the straight line B. In this embodiment: the adjusting spring 56 is a coil spring; one end of the coil spring is fixedly connected to the outer periphery of the sleeve 53; the other end of the coil spring is fixedly connected to the inner periphery of the drum 51; meanwhile, a receiving groove is provided at the inner circumferential surface of the drum 51.
The bowl 51 also includes a stop collar 513. A stop collar 513 is located at the inner periphery of the bowl 51. The surface of the stop collar 513 facing the central body 1 serves to press the sleeve 53 and cause the sleeve 53 to press against the end face of the outlet 13. At the same time, the limiting ring 513 is in sliding seal with the sleeve 53, and the sleeve 53 is in sliding seal with the end face of the outlet 13.

if the water outlet valve is opened, the water flow overcomes the elastic force F0 of the reset spring 4, the component force G1 of the gravity of the flow float assembly 3 along the moving direction of the flow float assembly 3 and the friction force F between the adjusting assembly 5 and the flow float assembly 3 to push the flow float assembly 3 to move, so that the medium output is realized;
the component force G1 decreases along with the increase of the included angle a, and the friction force F increases along with the increase of the included angle a, so that the movement resistance (the movement resistance is the sum of the elastic force F0, the component force G1 and the friction force F) of the flow float assembly 3 is controlled to be stable under the condition that the included angle a is different, and further the usability of the water pump pressure controller is guaranteed, so that the operation of the water pump is controlled normally.
