[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1-Figure 5 , a pipeline solenoid valve structure, comprising a valve body pipeline 40, wherein the valve body pipeline 40 is provided with a communication port 450, a cut-off pipeline 410 is provided in the communication port 450, and a communication flow channel 440 is formed in the cut-off pipeline 410;

[0027] The valve body pipes 40 on the left and right sides of the cut-off pipe 410 are provided with a water inlet channel 420 and a water outlet channel 430 , and the water inlet channel 420 is connected to the communication port 450 ;

[0028] One end of the communication channel 440 is communicated with the communication port 450 , and the other end thereof is communicated with the water outlet channel 430 ;

[0029] A connecting pipe 10 is also provided, the valve body pipe 40 is provided in the connecting pipe 10, a connecting seat 100 is provided on the connecting pipe 10, an opening 120 penetrating into the interior of the connecting pipe 10 is provided on the connecting seat 100, the communication port 450 is communicated with the opening 120, a mounting seat 20 is provided on the connecting seat 100, a valve head 30 is installed on the mounting seat 20, a floating seat 60 is connected to the lower end surface of the mounting seat 20, and the floating seat 60 can extend through the opening 120 to the communication port 450;

[0030] When the floating seat 60 is in contact with the upper end surface of the cut-off pipe 410, the end of the communication channel 440 connected to the communication port 450 is in a closed state;

[0031] When the floating seat 60 is separated from the upper end surface of the cut-off pipe 410 , the end of the communication channel 440 connected to the communication port 450 is in a communication state.

[0032] The utility model sets a double pipeline cooperation of a valve body pipeline 40 and a connecting pipeline 10, and the connecting pipeline 10 mainly plays a connecting role. The connecting pipeline 10 can be integrally injection molded with the main water supply pipeline. The valve body pipeline 40 is provided with a cut-off pipeline 410, and the cut-off pipeline 410 cooperates with the floating seat 60 to realize the opening or closing of the solenoid valve. It is precisely because of the existence of the cut-off pipeline 410 that this special shape of the flow channel makes it impossible for the existing valve body pipeline 40 to be injection molded into an integrated structure with the water supply main pipeline. The utility model uses a connecting pipeline 10 that is separately set up. Since there is no special flow channel structure inside the connecting pipeline 10, the connecting pipeline 10 can be injection molded with the water supply main pipeline. The connecting pipeline can be integrally injection molded with the water supply main pipeline, which can not only optimize the on-site assembly steps, but also make the connection between the connecting pipeline and the water supply main pipeline more stable and reliable.

[0033] See also Figure 2 and Figure 3 A plurality of positioning posts 240 are provided on the mounting seat 20, a first plug hole 130 is provided at a position of the connecting pipe 10 corresponding to the positioning post 240, a second plug hole 470 is provided at a position of the valve body pipe 40 corresponding to the positioning post 240, and the positioning post 240 is inserted into the first plug hole 130 and the second plug hole 470.

[0034] The setting of the positioning column 240 can constrain the assembly position of the valve body pipeline 40 and the connecting pipeline 10 to avoid misalignment of the valve body pipeline 40 and the connecting pipeline 10, so that the opening 120 and the connecting port 450 are aligned with each other, so that the floating seat 60 and the cut-off pipeline 410 correspond to each other.

[0035] See also Figure 2Any one of the second plug holes 470 is connected to the water outlet channel 430, any one of the positioning columns 240 passes through the first plug hole 130 and the second plug hole 470 and extends into the water outlet channel 430, and a drainage channel 250 is provided on the positioning column 240 extending into the water outlet channel 430; a water storage cavity 80 is provided between the floating seat 60 and the mounting seat 20, and a water inlet 610 connected to the communication port 450 is provided on the floating seat 60, and the water storage cavity 80 0 is provided with a spring 70 for applying a force to the floating seat 60; the mounting seat 20 is provided with a water inlet channel 220, a closed cavity 210 and a water delivery channel 230 which are connected in sequence, the water inlet channel 220 is connected with the water storage cavity 80, the valve plug 310 of the valve head 30 can be blocked in the closed cavity 210, so that the end of the closed cavity 210 connected to the water delivery channel 230 is in a closed state; the water delivery channel 230 is connected with the drainage channel 250.

[0036] A drainage channel 250 is provided using one of the positioning columns 240. This arrangement can allow water in the water storage chamber 80 to be discharged into the water outlet channel 430 through the water inlet channel 220, the closed chamber 210, the water delivery channel 230 and the drainage channel 250 when the valve head 30 controls the valve plug 310 to open. In this state, the floating seat 60 is pushed upward by the water flow force of the water inlet channel 420, and the floating seat 60 is in an open state. At this time, the water flow can flow from the water inlet channel 420 through the connecting port 450 into the connecting channel 440, and finally be output through the water outlet channel 430.

[0037] See also Figure 2 , a limiting ring 140 is provided at either end of the connecting pipe 10, one end of the valve body pipe 40 is fitted with the limiting ring 140 for limiting, a limiting groove 110 is provided on the limiting ring 140, and a limiting plug 460 movably plugged into the limiting groove 110 is provided at one end of the valve body pipe 40 close to the limiting ring 140. During assembly, the valve body pipe 40 is inserted into the connecting pipe 10 from the end without the limiting ring 140 until the limiting ring 140 is inserted into the limiting groove 110 and the end face of the valve body pipe 40 is fitted with the limiting ring 140, and the positioning assembly can effectively constrain the position of the connecting pipe 10 and the valve body pipe 40.

[0038] See also Figure 2 The outer wall of the valve body pipe 40 on the left and right sides of the cut-off pipe 410 is sleeved with a sealing ring 50, and the sealing ring 50 fits with the inner wall of the connecting pipe 10. This can effectively improve the sealing performance and prevent liquid from seeping from the connecting port 450 through the gap between the connecting pipe 10 and the valve body pipe 40.

[0039] See also Figure 3The valve head 30, the mounting seat 20 and the connecting seat 100 are fixedly connected in sequence by screws.

The plug-in cooperation between the positioning plug 400 and the positioning slot 101 can make the connecting pipe 10 and the valve body pipe 40 connected as a whole, so that the two will not rotate relative to each other.
