[0006] The beneficial effects of the present invention are as follows: during installation, first, the valve body is installed in the installation groove of the valve seat so that the two connecting pipes extend above the two clamping blocks respectively; then, the two clamping blocks are moved upward so that the two clamping blocks clamp the two connecting pipes respectively, so that the two clamping blocks abut against the other ends of the two limiting sleeves respectively, and one end of the two limiting sleeves abuts against the inlet end and the outlet end respectively;

[0007] When disassembling, move the two clamping blocks downwards so that the two clamping blocks respectively release the two connecting pipes, and then pull the two connecting pipes out from the inlet end and the outlet end respectively.

[0008] The invention has a simple structure and a reasonable design, and can realize the rapid disassembly and assembly of two connecting pipes at the inlet end and the outlet end of the valve body, and the disassembly and assembly is convenient, efficient, time-saving and labor-saving.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the valve seat is an L-shaped seat body, and the upper surfaces of the two ends of the L-shaped seat body are respectively provided with installation grooves, and the two clamping blocks are respectively installed in the two installation grooves, and their upper ends respectively extend outside the two installation grooves and can move up and down respectively.

[0011] The beneficial effect of adopting the above further solution is that the structure is simple, and it is more reasonable for the valve seat to adopt an L-shaped seat body, which is convenient for assembling various components.

[0012] Furthermore, the lower ends of the two clamping blocks are fixedly connected to the bottoms of the two mounting grooves through clamping springs.

When the two connecting pipes are assembled, the two limit rings are respectively in contact with the two limit sleeves, and at this time, the two return members are respectively in a compressed state;

[0019] During disassembly, the two clamping blocks loosen the two connecting pipes respectively. At this time, the two connecting pipes are ejected out of the inlet end and the outlet end respectively under the elastic force of the two return members, so that disassembly is more convenient.

[0020] Furthermore, the two limiting rings are respectively provided with annular grooves at one end close to the two limiting sleeves, and the two return members are respectively return springs, which are respectively installed in the two annular grooves, and their two ends are respectively abutted against the bottom of the two annular grooves and one end of the two limiting sleeves.

When the two connecting pipes are assembled, the two limit rings are respectively in contact with the two limit sleeves, and at this time, the two return springs are respectively in a compressed state;

[0022] During disassembly, the two clamping blocks loosen the two connecting pipes respectively. At this time, the two connecting pipes are ejected out of the inlet end and the outlet end respectively under the elastic force of the two return springs, making disassembly more convenient.

[0024] The beneficial effect of adopting the above further solution is that during assembly, two positioning columns can be respectively inserted into the two through holes and the two positioning grooves, further increasing the stability of the assembly of the two connecting pipes with the inlet end and the outlet end respectively.

[0025] Furthermore, positioning frames are fixedly installed on the inlet end and the outlet end respectively, and the two positioning columns are vertically installed on the two positioning frames respectively, and can be moved up and down and positioned respectively; the two positioning columns are respectively fixedly sleeved with limit plates, and the two positioning columns are respectively slidably sleeved with positioning springs, and the two ends of the two positioning springs are respectively abutted against the two limit plates and the two positioning frames; under the elastic force of the two positioning springs, one end of the two positioning columns can be respectively inserted into the two through holes and the two positioning grooves.

[0026] The beneficial effect of adopting the above further solution is that during assembly, the elastic force of the two positioning springs is used to insert the two positioning posts into the two through holes and the two positioning grooves respectively, further increasing the stability of the assembly of the two connecting pipes with the inlet end and the outlet end respectively;
