[0021] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings to facilitate a better understanding of the present invention.

[0022] like Figures 1 to 5The illustrated three-way one-way valve quick-connect connector, which can be installed with a pressure sensor, includes a three-way one-way valve body 1. The upper and lower portions of the three-way one-way valve body 1 are connected to a pressure sensor mounting seat 9 and a nozzle connector 2, respectively. The sides of the three-way one-way valve body 1 are connected to a backflush pipe connector 5 and a urea pipe connector 11, respectively. The backflush pipe connector 5 is mounted and connected to a backflush pipe connector 7. One end of the backflush pipe connector 7 is connected to a backflush pipe clamping port 6, which facilitates the installation and connection of the backflush pipe by simply snapping it into place. The backflush pipe clamping port 6 has multiple raised steps on the side, and a guide surface at the end of the backflush pipe clamping port 6 gradually reduces the cross-section of the end, facilitating the snap-in installation of the backflush pipe. The nozzle connector 2 has a nozzle connection port 3 in the middle, and a nozzle snap-in slot 4 and a self-locking device mounting seat 12 on the side of the nozzle connector 2. The self-locking device mounting seat 12 is used to mount the self-locking device. The provision of the nozzle snap-in slot 4 facilitates the installation and snap-in of the nozzle. The urea pipe connector 11 is provided with a plurality of raised steps on its side, and a guide surface is provided at the end of the urea pipe connector 11, which gradually reduces the cross-section of the end, making it easier for the urea pipe to be inserted and installed. The backflush pipe connector 5 and the urea pipe connector 11 are arranged at a 90-degree angle on the side of the three-way one-way valve body 1, which facilitates the installation and connection of the backflush pipe and the urea pipe. There are mounting holes 10 on both sides of the pressure sensor mounting seat 9, which facilitates the positioning and installation of the pressure sensor. A through groove is provided at the bottom of the pressure sensor mounting seat 9, and a plurality of reinforcing ribs 8 are provided in the through groove, which can not only reduce the weight of the pressure sensor mounting seat, but also enhance the strength of the pressure sensor mounting seat 9. The nozzle connector 2 is arranged in a square shape, and grooves are provided at the four corners to facilitate the connection and installation of the nozzle. A winding groove 13 is provided on the side of the three-way one-way valve body 1, and the winding groove 13 is used to install the heating wire.
