[0027] The water replenishing joint assembly comprises a valve 1, a first joint 2 and a second joint 3 assembled at both ends of the valve 1, wherein the valve 1 is a water replenishing valve, generally a ball valve, which is provided with a handle for an operator to hold and operate, as shown in Figure 1 ;

[0028] The first joint 2 comprises a tower joint 201 and a one-way valve 202, which are assembled into one or integrally formed, and is arranged at one side of the valve 1 in the fluid flow direction. Specifically, one end of the tower joint 201 is connected with the valve 1, and the other end is connected with the tower joint 201. A filter screen 203 is arranged between the tower joint 201 and the one-way valve 202, and is used to filter the liquid impurities flowing into the one-way valve 202, i.e. the liquid impurities flowing into the valve 1.

[0029] One end of the tower joint 201 towards the one-way valve 202 is provided with a filter cavity 204, and the filter screen 203 is arranged in the filter cavity 204, and the filter cavity 204 is in abutment with the end face of one side of the one-way valve 202. One end of the one-way valve 202 towards the tower joint 201 is provided with a connecting part 205 connected with the tower joint 201, and the filter screen 203 is arranged between the connecting part 205 and the right end face of the filter cavity 204.

[0030] The one-way valve 202 is fixedly connected with the tower joint 201 through the connecting part 205, and the fixing mode can be riveting, welding or seamless integral forming to realize the integrated one-way valve 202 and the tower joint 201.

[0031] One end of the one-way valve 202 close to the valve 1 is fixedly provided with a fifth joint 206, and a first sealing gasket 207 is arranged between the fifth joint 206 and the valve 1. The fifth joint 206 and the valve 1 are fixed by thread cooperation, and the two ends of the first sealing gasket 207 abut against the end face of the fifth joint 206 and the end face of the valve 1 respectively, so as to realize the assembly sealing between the first joint 2 and the valve 1.

[0032] The one-way valve 202 and the fifth joint 206 can be assembled to realize the integration by seamless welding, thread or riveting, etc. After the valve core assembly is assembled into the one-way valve 202, the one-way valve 202 and the tower joint 201 are integrated to form the first joint 2 by the above-mentioned way, and then the whole first joint 2 is fixed with the valve 1 by thread assembly.

[0033] By the above-mentioned connection, the original tower joint 201, a plurality of adapters and the one-way valve are integrated into a single module to form the integral first joint 2, which is convenient for subsequent assembly and reduces the leakage points.

[0034] The second connector 3 is integrally formed and includes a steel pipe 301 connected to the valve 1 and a third connector 302 and a fourth connector 303 integrally formed with the steel pipe 301. The steel pipe 301 is the main pipeline, and a bend 304 is provided at one end near the valve 1, while the rest are straight pipe sections 305. One end of the bend 304 is connected to the valve 1, and the other end is connected to the third connector 302 through the straight pipe section 305.

[0035] The bent portion 304 extends towards one end of the valve 1 and narrows its outer diameter to form a mating portion 306 connected to the valve 1. A second sealing gasket 307 is provided between the mating portion 306 and the valve 1 and is fixedly connected to the valve 1 by means of threaded fastening. The two ends of the second sealing gasket 307 abut against the end face of the mating portion 306 and the end face of the valve 1, respectively, to achieve a seal between the mating portion 306 and the valve 1.

[0036] The bent portion 304 and the straight portion 305 are seamlessly connected and precision cast in one piece, such as... Figure 1 As shown, the end of the straight pipe section 305 away from the valve 1 is fixed to the third connector 302 and integrally cast with precision. The fourth connector 303 is located on the outer wall of the straight pipe section 305, and the axis of the fourth connector 303 is perpendicular to the axis of the straight pipe section 305. The fourth connector 303 and the straight pipe section 305 are also integrally cast with precision. The fourth connector 303 and the third connector 302 are in a through-hole state with the inner hole of the steel pipe 301. When the fluid flows into the steel pipe 301 from the valve 1, it can flow out through the third connector 302 or the fourth connector 303.

[0037] The third connector 302 is connected to the main unit pipeline; the fourth connector 303 is connected to the hose. The second connector 3 can preferably be made of stainless steel or copper and other metals for precision casting. The original valve adapter, steel pipe, steel pipe elbow, CQC20 connector, G1 / 2-1" external thread adapter and 1" external thread welding head are integrated into a seamless integral structure, realizing the integral precision casting of the entire second connector 3.

[0038] With the above structure, the entire water supply connector assembly is simplified to valve 1 and first connector 2 and second connector 3 connected to both ends of valve 1. This simplifies the overall structure, reduces welding points and leakage points, and greatly improves the assembly efficiency of the entire water supply connector assembly.
