Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A straight-through valve easy to assemble and disassemble is shown in figures 2-6 and comprises a shell 1, a valve element 2, a nut 3, a buckle 4 and a connecting pipe 5, wherein a through liquid through hole 11 is axially formed in the shell 1, a mounting hole 12 matched with the valve element 2 is formed in the shell 1, the valve element 2 is rotatably arranged in the mounting hole 12 to control the liquid through hole 11 to be opened or closed, the connecting pipe 5 is fixed outside the box, one end of the connecting pipe 5 extends into the box and is fixed with one end of the shell 1 through the buckle 4, and the other end of the shell 1 is connected with a pipeline through the nut. Through the structure, the connecting pipe 5 and the box body can be simultaneously embedded into the wall body, one end of the connecting pipe 5 extends into the box body, and then the connecting pipe can be connected with the shell 1 through the buckle 4, when the through valve needs to be maintained, only the buckle 4 needs to be removed, and the nut at the other end needs to be removed, so that the through valve can be removed. Greatly reducing the maintenance difficulty and the maintenance cost.

In one embodiment, as shown in fig. 2-6, a fixing portion 51 is disposed on a side wall of the connecting pipe 5, and the fixing portion 51 is fixedly connected to an outer wall of the water tank. In one embodiment, the fixing portion 51 may be fixed to the case by screws. The fixing part 51 can be adhered and fixed with the box body through glue; after being embedded into the wall, the box body can be blocked by cement, and the box body can be ensured to be fixed with the connecting pipe 5.
