When people use water hoses for long-distance transportation, they are usually connected to rubber hoses. However, when the faucet is suddenly opened, the pressure is unstable, and the speed of the liquid in the water pipe changes sharply in a short period of time. Before the speed of the static liquid in the rubber pipe has not changed, it is pushed by the liquid with a large flow rate. According to The characteristics of the poor compressibility of the fluid show that the liquid at this time is pushed like a solid, so that the liquid has an excessive impact on the water pipe. In the long run, the ductility of the rubber pipe becomes poor, and the rubber water pipe is easily damaged.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

A water flow buffering device as shown in Figures 1 to 5 includes a buffer housing 1, a piston disc 2, a regulating disc 3 and an end cover 4; the piston disc 2 and regulating disc 3 are sequentially sleeved on the buffer housing 1, the end cover 4 covers the opening of the buffer housing 1, and is rotatably connected with the regulating plate 3. A plurality of pressure regulating springs 5 are arranged between the piston plate 2 and the regulating plate 3. The two ends of the compression spring 5 are respectively connected with the piston disc 2 and the regulating disc 3. The buffer housing 1 is provided with a stepped surface 106, and the piston disc 2 is in pressing contact with the stepped surface 106 to form a limit. The casing 1 is provided with a water inlet pipe 101 and a water outlet pipe 102 , and the water inlet pipe 101 and the water outlet pipe 102 are both communicated with the inner cavity of the buffer casing 1 . The water inlet pipe 101 is connected with a water tap, and the water outlet pipe 102 is connected with a connecting hose for transporting water. When the opening pressure of the faucet is unstable, the water entering the inner cavity of the buffer housing 1 will press the piston disc 2. When the water inlet pressure is large, the piston disc 2 compresses the pressure regulating spring 5 to increase the volume of the inner cavity of the buffer housing 1. , thereby reducing the pressure when the water is discharged through the water outlet pipe 102 .

The opposite surfaces of the piston plate 2 and the adjustment plate 3 are provided with a plurality of fixed columns 6, and the fixed columns 6 on the piston plate 2 and the fixed columns 6 on the adjustment plate 3 are opposite one by one. Both ends of the spring 5 are sleeved and connected with the fixed column 6 . The sum of the heights of any two opposite fixed columns 6 is greater than the height of the pressure regulating spring 5 when it is compressed to the shortest. When the piston disc 2 is compressed to a certain degree, the two opposite fixed columns 6 press against each other to prevent the pressure regulating spring 5 from being further compressed, so as to avoid damaging the pressure regulating spring 5; the end cover 4 is provided with a top column 401 inside, so The top column 401 and the adjusting plate 3 are rotatably connected through the bearing 7. At this time, when the end cover 4 can be rotated, the volume in the buffer housing is further enlarged, and the pressure is further adjusted. Through the pipe thread sealing connection, the piston disc 6 and the adjusting disc 6 are both provided with a piston seal.
