Description

An improved structure of the water inlet and outlet pipe body of the water inlet valve

technical field

The utility model relates to the technical field of water inlet valves, in particular to an improved structure of a water inlet and outlet pipe body of a water inlet valve.

Background technique

In the prior art, the water inlet valve includes a valve body, a top cover, a water-stop pad, a swing arm, a buoy and a buoy water tank; one end of the valve body is connected to a water inlet and outlet pipe, and the water inlet and outlet pipe is composed of the water inlet pipe and the outlet pipe wrapped in the water inlet pipe. One end of the water inlet pipe is longer than the water outlet pipe, and the end of the water inlet pipe longer than the water outlet pipe is connected to the water supply pipe outside the water tank. During installation (for example, it is applied to a toilet), the water inlet pipe passes through the installation hole at the bottom of the toilet, and with the help of connectors (such as Nut) is connected to the external water supply pipe. When disassembling this structure, the water tank must be opened, the connecting piece at the bottom of the water tank must be operated first, and then the water inlet pipe of the water inlet and outlet pipes is withdrawn from the installation hole. Therefore, the disassembly process of the existing water inlet and outlet pipe structure is relatively difficult. Complicated, due to the structural characteristics of the toilet, the disassembly structure of the water inlet pipe and the water supply pipe at the bottom of the toilet is not easy to operate.

In order to overcome the above-mentioned shortcoming, the inventor specially developed an improved structure of the water inlet and outlet pipe body of the water inlet valve that is easy to disassemble, and this case arose from it.

Utility model content

The purpose of this utility model is to provide an improved structure of the water inlet and outlet pipe body of the water inlet valve, which can realize the quick disassembly and assembly of the water inlet and outlet pipe body in the water tank, improve the efficiency of the maintenance and replacement operation of the water inlet valve, and reduce the risk of damage to the water inlet and outlet pipes at the same time .

In order to achieve the above object, the technical scheme of the utility model is as follows:

An improved structure of the water inlet and outlet pipe body of the water inlet valve, comprising:

an intermediate pipe consisting of the first section of the inlet pipe and the outlet pipe; and

A connecting pipe formed by the second section of the water inlet pipe, which is used to pass through the installation hole and connect with the water supply pipe outside the water tank;

The first section of the water inlet pipe is detachably connected with the connecting pipe.

The top of the connecting pipe forms a mounting base, and a plurality of slots are formed on the mounting base. The lower end of the first section of the water inlet pipe forms an inner pipe that can be inserted into the water inlet channel of the connecting pipe, and the outer peripheral surface of the upper end of the inner pipe forms a For the butt-fitted installation top seat, a plurality of clips are formed in the corresponding slots on the installation top seat. When the inner pipe is inserted into the water inlet channel of the connecting pipe, the clips and the slots form a snap fit.

The inner wall of the water inlet channel of the connecting pipe forms a plurality of stoppers, the outer peripheral surface of the lower end of the inner pipe forms a plurality of stoppers, and a channel for the stoppers to pass is formed between two adjacent stoppers.

One or more annular grooves are formed on the outer peripheral surface of the inner pipe, and an O-ring is installed on the annular grooves.

After adopting the above scheme, the utility model divides the water inlet pipe into two sections, wherein the second section of the water inlet pipe is installed in the installation hole of the water tank as a connecting pipe, and only the first section of the water inlet pipe and the connecting pipe need to be disassembled It only needs to be divided without operating the connecting pipe, and the quick disassembly and assembly of the valve body can be realized, which can effectively improve the work efficiency of the maintenance and replacement of the water inlet valve.

Label description

Intermediate pipe 1, first section of water inlet pipe 11, water outlet pipe 12, inner pipe 13, stopper 14, annular groove 15, connecting pipe 2, limit block 21, installation base 3, slot 31, top seat 4, snap Fast 41, O-ring 5, valve body 6, nut 7.

Detailed ways

As shown in Figures 1 and 2, the utility model discloses an improved structure of the water inlet and outlet pipe body of the water inlet valve, including: an intermediate pipe 1 composed of the first section 11 of the water inlet pipe and the water outlet pipe 12; and

A connecting pipe 2 formed by the second section of the water inlet pipe, which is used to pass through the installation hole and connect with the water supply pipe outside the water tank;

The first section 11 of the water inlet pipe is connected to the connecting pipe 2 in a detachable manner.

In order to facilitate the disassembly and assembly of the connecting pipe 2 and the intermediate pipe 1, the top of the connecting pipe 2 forms a mounting base 3, and a plurality of slots 31 are formed on the mounting base 3. Inner pipe 13, the outer peripheral surface of the upper end of inner pipe 13 forms the installation top seat 4 that docks with the installation base 3, and the corresponding card groove 31 on the installation top seat forms a plurality of fastening blocks 41, when the inner pipe 13 is inserted into the water inlet of the connection pipe 2 During passage, the card fast 41 forms a snap fit with the card slot 31 .

The inner wall of the water inlet channel of the connecting pipe 2 forms a plurality of stoppers 21, the outer peripheral surface of the lower end of the inner pipe 13 forms a plurality of stoppers 14, and a passage for the stoppers 14 to pass is formed between two adjacent stoppers 21 .

In order to improve the tightness of the water inlet and outlet pipes, one or more annular grooves 15 are formed on the outer peripheral surface of the inner pipe 13, and O-shaped sealing rings 5 are installed on the annular grooves 15. After the O-shaped sealing rings 5 can be inserted into the connecting pipe 2 in the inner pipe 13, Prevent water from flowing out of its gaps.

When the utility model is installed, the stopper 14 is aligned with the channel between the limit buckles 21 so that the inner tube 13 of the intermediate pipe 1 is inserted into the connecting pipe 2, and then the intermediate pipe 1 is rotated clockwise or counterclockwise so that the top seat 4 is installed. The fast card 41 is snapped into the card slot 31 to realize the assembly of the water inlet and outlet pipes. When disassembling, the intermediate pipe 1 is again released to release the clamping relationship between the card fast 41 and the card slot 31, and then the stopper 14 is aligned with the limit buckle 21 The channel between makes the intermediate pipe 1 be pulled out from the connecting pipe 2. It can be seen that the installation and disassembly process of the utility model is very convenient, the efficiency is high, and the loss of the water inlet and outlet pipe body is small.

As shown in Figure 6, when the utility model is applied to the valve body 6, the first section 11 of the water inlet pipe and the water outlet pipe 12 are connected to the valve body 6 (respectively connected to the water inlet and the water outlet), and the outer peripheral surface of the connecting pipe 2 forms an outer surface. Threaded structure, the connecting pipe 2 is inserted into the installation hole at the bottom of the water tank from top to bottom, the nut 7 is screwed into the connecting pipe 2 from below to fix it in the installation hole, and the inner pipe 13 of the first section 11 of the water inlet pipe can be easily inserted Or pull out and connecting pipe, like this, the water inlet pipe first section 11 and the outlet pipe 12 communicate with the valve body and just can be easily taken out from the water tank, realize fast disassembly.

The above are only specific embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. All equivalent changes made according to the design idea of this case fall within the scope of protection of this case.
