Technical Field

[0001] The present application relates to the field of pipeline valve groups, and in particular to a valve group that can be used for flushing the end of a pipeline. Background Art

[0002] Air conditioning is one of the commonly used electrical appliances nowadays. Air conditioning is an air conditioner, which refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. It generally includes cold source / heat source equipment, cold and hot medium distribution system, terminal device and other major parts and other auxiliary equipment. Various connecting pipes are required when installing air conditioning.

[0003] After welding, the air-conditioning pipeline needs to be flushed to wash away welding slag, mud, sand and other debris generated during the construction process. The conventional practice is to remove the flexible joint at the terminal equipment connection and weld a short pipe to connect the return water pipe of the air-conditioning pipeline. At the end of the air-conditioning pipeline, the air-conditioning box has many interfaces, which makes disassembly and installation troublesome. In addition, the connecting short pipe is time-consuming, labor-intensive and material-intensive to make, and it has no use value after the pipeline is flushed. Utility Model Content

[0031] See also Figure 1-Figure 5 The present application provides a valve group that can be used for pipeline end flushing, including a regulating valve assembly 100 and a support assembly 200.

[0032] See also Figure 1 and 2The regulating valve assembly 100 includes a water supply pipe 110, a return pipe 120, a first control valve 130, a second control valve 140 and a third control valve 150. The return pipe 120 is arranged on one side of the water supply pipe 110, the first control valve 130 is connected to the water supply pipe 110, the third control valve 150 is connected to the return pipe 120, and the second control valve 140 is connected between the water supply pipe 110 and the return pipe 120.

[0033] The water supply pipe 110 and the water return pipe 120 are connected via a support plate 111 , and the support plate 111 is provided to stably support the water return pipe 120 in the water supply pipe 110 .

[0034] In a specific implementation, the water supply pipe 110 and the return pipe 120 are connected via a connecting pipe 170, and the second control valve 140 is connected and arranged in the connecting pipe 170. The connecting pipe 170 is used to connect the water supply pipe 110 and the return pipe 120, and the second control valve 140 is arranged to control the opening and closing of the connecting pipe 170.

[0035] See also Figure 1 , 2 , 3, 4 and 5, the support assembly 200 includes a support leg 210, an adjustment disk 220 and a support rod 240, the support leg 210 is arranged at the bottom of the adjustment disk 220, the support rod 240 is arranged at the top of the adjustment disk 220, and the water supply pipe 110 is installed on the top of the support rod 240.

[0036] Among them, the adjustment disk 220 includes a base 221, a turntable 222 and a positioning rod 223. The turntable 222 is rotatably set on the top of the base 221. The positioning rod 223 runs through the base 221 and the turntable 222. By setting the base 221, the turntable 222 and the positioning rod 223, the turntable 222 is rotated on the top of the base 221, and then the positioning rod 223 is used to limit the turntable 222, so as to determine the angle.

[0037] In a specific implementation, a groove 2211 is provided on the top of the base 221, and the turntable 222 is rotatably disposed in the groove 2211. The groove 2211 is provided to limit the rotation of the turntable 222 and guide the turntable 222 to be stably rotated and connected.

[0038] It should be noted that a T-shaped shaft 2221 is provided at the bottom of the turntable 222 , and the T-shaped shaft 2221 is rotatably provided at the bottom of the groove 2211 . By providing the T-shaped shaft 2221 , the turntable 222 and the base 221 can be rotated and stably connected.

[0039] Specifically, the turntable 222 is provided with a plurality of positioning holes 2222 , and the plurality of positioning holes 2222 are evenly arranged. The positioning rod 223 passes through the positioning holes 2222 and the base 221 . The plurality of positioning holes 2222 are provided to realize positioning through the positioning rod 223 after the turntable 222 is rotated.

[0040] In a specific implementation scheme, a pull ring 2231 is fixedly connected to the top of the support rod 240. The support rod 240 and the pull ring 2231 are an integrated structure. By setting the pull ring 2231, it is convenient to pull the pull ring 2231 to operate to take and place the support rod 240. The integrated structure is easy to operate and has high structural strength and durability.

[0041] The working principle of the valve group that can be used for flushing the end of the pipeline is as follows: during use, under normal circumstances, the water supplied to the machine room enters from the water supply pipe 110, is transported to the air-conditioning equipment, and then returns to the water room through the return pipe 120, thereby realizing circulation. At this time, the first control valve 130 is opened, the second control valve 140 is closed, and the third control valve 150 is opened. When it is necessary to flush the inside of the pipeline, the first control valve 130 is closed, the second control valve 140 is opened, and the third control valve 150 is closed. The water connecting pipe 170 in the water supply pipe 110 enters the return pipe 120 instead of the air-conditioning equipment. The sewage can be discharged through the discharge valve of the return pipe 120, so that the inside of the pipeline can be cleaned regularly when necessary. At the same time, the positioning rod 223 can be removed first to rotate the turntable 222 to drive the valve group to rotate and adjust the direction, and then the positioning rod 223 can be used to pass through the positioning hole 2222 and the hole on the base 221 for positioning, which greatly improves practicality.
