Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

As described in the background art, in the prior art, a water pump unit is connected with a water inlet and outlet pipeline through a flexible pipe, and vibration is absorbed through the flexible pipe, so that the vibration of the water pump unit is prevented from being transmitted to the water inlet and outlet pipeline. If the flexible pipe is adopted for connection, the flexible pipe is limited by materials and the environment of a water pump room, has short service life, needs to be replaced more frequently, and is not beneficial to equipment maintenance and stable operation of a water supply system. The waterproof connection structure of pipeline for water supply unit that this embodiment provided has good waterproof performance simultaneously in order to have at the shock attenuation.

As shown in fig. 1-2, the overall appearance of the water-proof connection structure for the pipeline of the water supply unit is shown.

The waterproof pipeline connecting structure is used for fixing the first pipe orifice 3a and the second pipe orifice 3b of the pipeline. The main connections are a clamp 1 and an elastic sealing block 2. The clamp clamps the interface of the first pipe orifice 3a and the second pipe orifice 3b, and presses the elastic sealing block 2 to seal and prevent water. An inter-pipe gap 4 exists between the first pipe orifice 3a and the second pipe orifice 3a, one part of the elastic sealing block 2 is filled in the inter-pipe gap 4, and the other part of the elastic sealing block is filled between the hoop and the outer walls of the first pipe orifice and the second pipe orifice.

Elastic sealing piece 2 can carry out waterproof sealing under the oppression of clamp, simultaneously, because 2 parts of elastic sealing piece are filled in intertube clearance 4, fill intertube clearance 4 between clamp and the orificial outer wall of first mouth of pipe, second again, the direct rigid connection of avoiding can effectively cushion the vibration that water pump unit transmitted on the pipeline. The service life is also relatively long compared to flexible pipes.

As shown in fig. 3-5, the clip and the resilient seal block are shown in detail and in cooperation with each other and the nozzle.

Clamp 1 is for the components of a whole that can function independently structure, and the direction of components of a whole that can function independently is for following the pipeline axial, including first clamp piece 11a, second clamp piece 11b, first clamp piece passes through the fastener with the second clamp piece and can dismantle fixedly, and is right the sealing block has radial inward pressure.

The outer wall of first mouth of pipe 3a and the second mouth of pipe 3a is equipped with annular groove 5, clamp 1 set up with annular groove 5 complex annular bulge 12, shape recess section is isosceles trapezoid. Isosceles trapezoid's setting has a hypotenuse, just turns into the power that makes two mouth of pipe axial be close to with the radial centripetal power of two clamps when making the clamp chucking, compresses tightly elastic sealing block 2.

The elastic sealing block 2 comprises a cylindrical part 21 and a protruding part 22, wherein the protruding part 22 is an annular protrusion of the cylindrical part 21 to the pipe gap. When the clamping band is clamped, the radial centripetal force of the two clamping bands is converted into the force for enabling the two pipe orifices to be close to each other axially, and the elastic sealing block 2 is pressed, namely the protruding portion 22 is pressed.

The height of the bulge 22 may be equal to the thickness of the nozzle wall. The height of the protrusion 22 may be slightly less than the thickness of the tube wall, so that when squeezed, the water resistance is not increased due to the exposure of the inner wall of the tube.
