Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the embodiment discloses a quick coupler for a water pump, which includes an installation cylinder 1 in threaded connection with a water outlet pipe of a pump body, wherein one end of the installation cylinder 1, which is far away from the water outlet pipe, is in threaded connection with a coupler 2, a sealing ring 3 is arranged between the coupler 2 and the water outlet pipe, an outer edge of the sealing ring 3 is provided with an edge 301 in an extending manner, and the edge 301 is wrapped on the outer side of the water outlet pipe; a chuck 201 abutting against the sealing ring 3 is arranged at the periphery of one end, close to the water outlet pipe, of the joint 2 in an extending manner, a sealing groove 202 is formed in one surface, abutting against the sealing ring 3, of the chuck 201, a sealing air bag 203 is arranged on the sealing groove 202, a fluid channel 204 is further arranged on the joint 2, and a liquid inlet pipeline 205 communicated with the sealing groove 202 is arranged on the inner wall of the fluid channel 204; the sealing ring 3 is also provided with a V-shaped groove 302 corresponding to the sealing air bag 203, and the sealing air bag 203 is positioned in the V-shaped groove 302;

as shown in fig. 1, when the water pump is started, the water flow released by the water pump from the water outlet pipe enters the fluid channel 204, and when the instantaneous water pressure of the water pump is too high when the water pump is started, as shown in fig. 2, the water flow enters the annular sealing groove 202 through the liquid inlet channel 205, and the sealing air bag 203 is expanded, so that the water pressure can be buffered; meanwhile, the sealing air bag 203 is positioned in the V-shaped groove 302, when the sealing air bag 203 expands, the wrapping edge 301 is extruded towards two sides, so that the sealing strength between the water outlet pipe and the mounting cylinder 1 is enhanced, and liquid leakage caused by high-pressure water flow impact at the joint is avoided; when the pressure in the liquid inlet channel 205 becomes small or the water pump is turned off, the liquid is pushed out of the sealing groove 202 by the elastic restoring force of the edge cover so as to shrink the sealing bladder 203 because the pressure in the liquid channel 204 is smaller than the pressure in the sealing groove.

In this embodiment, the one end that the outlet pipe was kept away from to installation section of thick bamboo 1 is provided with spread groove 4, spread groove 4 and chuck 201 week side threaded connection.

A locking groove 5 is formed in one end, far away from the water outlet pipe, of the connecting groove 4, the diameter of the locking groove 5 is larger than that of the connecting groove 4, and the direction of threads on the inner wall of the locking groove 5 is opposite to that of threads on the inner wall of the connecting groove 4; a locking block 6 which is propped against the chuck 201 is connected with the locking groove 5 through internal threads;

as shown in fig. 1, a sealing block is further arranged between the locking block 6 and the chuck 201, the locking block 6 can have a certain compression effect on the chuck through the sealing block, and the directions of the threads in the connecting groove 4 and the locking groove 5 are opposite, so that the chuck 201 and the mounting cylinder are prevented from loosening and falling off due to vibration of the water pump during operation in the use process, the connection firmness is improved, and meanwhile, the sealing effect of the connection position is better;

as shown in fig. 2 to 5, a check valve 7 for closing the liquid inlet pipe 205 is arranged at the opening of the liquid inlet pipe 205, and the check valve 7 is used for preventing the internal liquid from flowing out; a liquid discharge pipeline 206 communicated with the sealing groove 202 is further arranged in the fluid channel 204, an arched pipeline 207 is arranged at the joint of the liquid discharge pipeline 206 and the fluid channel 204, both ends of the arched pipeline 207 are communicated with the fluid channel 204,

during normal use, as shown in fig. 3, when liquid flows through the arc-shaped pipe 207, the liquid will flow along the inner wall of the arc-shaped pipe 207 due to the viscosity of the liquid, and meanwhile, the inner diameter of the pipe is reduced due to the protrusion arranged in the liquid discharge pipe 206, so that the liquid in the fluid passage 204 is difficult to enter the sealing groove through the liquid discharge pipe 206, and even a small amount of liquid passing through the liquid discharge pipe will return to the fluid passage 204 again due to the fast flow velocity at one end of the arc-shaped pipe 207, which will not have a great influence on the use of the joint;

when the water pump is started, instantaneous high pressure can be generated in the fluid channel 204, as shown in fig. 4-5, the check valve 7 can be opened, water flow can enter the sealing groove through the liquid inlet channel 205 at the moment, liquid entering the sealing groove can be discharged through the liquid discharge channel at the moment, the liquid inlet quantity can be larger than the liquid outlet quantity because the inner diameter of the liquid discharge channel is smaller than that of the liquid inlet channel, the sealing airbag still can be expanded, and the sealing airbag is prevented from being damaged due to the fact that liquid in the sealing groove is too much caused by too much water pressure;

after the transient high pressure is over, the check valve 7 is closed to seal the liquid inlet channel 205, no liquid enters the sealing groove, and the liquid in the sealing groove is slowly discharged under the action of the liquid discharge channel and the arc-shaped pipeline.

In this embodiment, a barb 8 is disposed on an outer side of one end of the joint 2 away from the water outlet pipe.

In this embodiment, a handle 9 for controlling the rotation of the mounting cylinder 1 is arranged on the outer wall of the mounting cylinder 1; the handle 9 can facilitate the disassembly of the mounting cartridge.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
