Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Referring to accompanying drawings 1-11, in this embodiment, two types of spherical valve core and axial valve core are mainly introduced, and the water outlet in the valve core mainly introduces a three-way water outlet in a "T" shape structure, a There are three structural forms of the two-way water outlet with an angle of 120° and the two-way water outlet with a vertical angle of 90°. Since the valve core is movable inside the valve, as long as it is a similar structure that those skilled in the art can think of through this embodiment The structural forms of the spool and the water outlet should all be within the protection scope of the present invention.

This water pipe antifreeze valve includes an antifreeze valve body 1 and a spool movably arranged in the antifreeze valve body. The top of the antifreeze valve body 1 is provided with a switch control port 2 . A water outlet is provided on one side of the valve core, and a rotary switch 9 is provided on the top of the valve core.

The spool is a spherical spool 8 or an axial spool 12 .

The water outlet in the spool is a three-way water outlet 10 in a "T" shape.

The water outlet in the spool is a bidirectional water outlet 11 at an angle of 120°.

The water outlet in the spool is a two-way water outlet vertically at an angle of 90°.

Depending on the actual situation, you can choose one of the water outlet forms for installation.

The spool can be made into valves of other models or specifications according to actual needs, especially the shaft-shaped spool can be used for connection with large flange valves. In order to improve the sealing effect of the antifreeze valve body, a seal is installed at each water outlet of the antifreeze valve body.

This running water pipe antifreeze valve is installed on the water pipe in groundwater well 5, and groundwater well 5 is made up of a plurality of side plates and an upper cover plate 18, and the edge of side plate is all provided with groove 14 and projection 16 for assembling.

The water pipes in the present embodiment are divided into underground water pipes 6 and ground water pipes 7, wherein:

The underground water well is composed of multiple side plates and an upper cover plate, and the edges of the side plates are provided with grooves and projections for assembly. The side plate of groundwater well comprises long side plate 15 and short side plate 17, and in the present embodiment, the two ends of long side plate 15 are provided with groove 14, and the two ends of short side plate 17 are provided with projection 16, groove and The setting of the bump is relatively random, and it is set according to the actual template situation. The grooves and protrusions correspond to each other for easy assembly.

The valve installed on the underground water pipe 6 is an antifreeze valve body 1, and the antifreeze valve body 1 is provided with a water outlet 3 and a water outlet 4 that are connected to each other inside, and the water outlet 4 and the water outlet 3 are vertically arranged. The top of the antifreeze valve body 1 is provided with a switch control port 2 . The inside of the spool in the antifreeze valve body 1 is provided with a water outlet, and the top of the spool is provided with a rotary switch 9 . The water outlet 3 is used to communicate with the water pipe, and the drain outlet is used to discharge the stored water. The spool is movable inside the valve, and the rotary switch 9 is opposite to the switch control port 2, which is convenient for switch operation. The water outlet is relatively communicated with the water outlet or the water outlet, and then the relative position of the valve core in the valve is changed by controlling the rotary switch, thereby changing the connection between the water outlet and the water outlet.

In order to facilitate switch control, the antifreeze valve is also equipped with a switch handle 13 . The bottom end of the switch handle 13 is a fork-shaped structure. The switch handle 13 is used to control the valve switch outside the underground water well 5 .

Ground water pipe 7 stretches out underground water well 5 through the water pipe outlet 20 on the upper cover plate 18, and underground water well 5 is placed underground, and upper cover plate 18 is flush with the ground or slightly higher than the ground. Stretch into the operating port 19 on the upper cover plate 18 with the switch handle 13, then the lower end of the switch handle stretches into the switch control port 2 of the valve, then by cooperating with the rotary switch to control the switch of the valve. By rotating the position of the spool, controlling the relative position of its water outlet and water outlet or drain outlet to realize the on-off of water flow.

The principle of the utility model is: take the spherical valve core 8 of the three-way water outlet 10 as an example. Install the valve core inside the valve. In the season with high temperature or when water needs to be released, connect the E end and F end of the three-way water outlet with the water outlets at both ends of the valve, and the C end is opposite to the inner wall of the valve body. In this way, Can ensure the smooth flow of water. And when the temperature is low and easy to freeze, after the water is released, turn the valve core 90° clockwise through the rotary switch, so that its C end communicates with the water outlet opposite to the ground water pipe, while the E end of the valve core communicates with the water outlet of the water pipe on the ground. The drains are connected, and the F end is opposite to the inner wall of the valve body, so that the water stored in the above-ground water pipe can be directly discharged to the ground through the drain, so as to prevent the water stored in the above-ground water pipe from freezing and cause the water pipe to freeze.
