The water cooling clamp 300 is disposed at the periphery of the check valve 100, and a welding position (denoted as P) between the check valve 100 and the connection pipe 200 extends beyond the water cooling clamp 300, that is, the water cooling clamp 300 encloses a through space for placing the check valve 100, the check valve 100 is disposed in the through space, and both ends of the check valve 100 respectively extend out of the through space so as to be welded to the connection pipe 200.

The water-cooling clamp 300 is attached to the outer peripheral wall of the check valve 100 to improve the water-cooling effect of the check valve 100.

The water-cooling clamp 300 achieves the water-cooling of the check valve 100 through the following modes: a water containing cavity (not marked) is formed inside the water cooling clamp 300, a water inlet pipe 410 and a water outlet pipe 420 which are communicated with the water containing cavity are arranged on the water cooling clamp 300, cold water flows into the water containing cavity through the water inlet pipe 410, the temperature of the water cooling clamp 300 is reduced, heat generated by the check valve 100 and the connecting pipe 200 during welding is absorbed, the check valve 100 is cooled, meanwhile, the temperature of the cold water in the water containing cavity is increased to be hot water, the hot water flows out of the water outlet pipe 420, and the operation is repeated in a circulating mode, so that the check valve 100 is guaranteed to be kept at a low temperature all the time in the welding process.

Furthermore, the water flows inside the water-cooled clamp 300, avoiding from the root the risk of water entering inside the non-return valve 100.

In the operation process, the water-cooling clamp 300 is only required to be manually sleeved outside the check valve 100, the operation is simple, and the welding efficiency of the check valve pipe group is improved.

In some embodiments of the present application, a water flow channel is disposed in the water containing cavity, the water inlet pipe 410 and the water outlet pipe 420 are respectively communicated with the water flow channel, and cold water flows into the water flow channel through the water inlet pipe 410, flows to the water outlet pipe 420 along the water flow channel, and is designed according to a reasonable layout of the water flow channel, so that the improvement of the heat exchange efficiency and the uniformity of water cooling is facilitated.

In some embodiments of the present application, the water inlet pipe 410 and the water outlet pipe 420 are respectively connected to the water tank, and water in the water tank flows to the water inlet pipe 410 under the action of the water pump, and then flows back to the water tank through the water outlet pipe 420 after passing through the water containing cavity.

A temperature sensor is arranged in the water tank, so that the temperature of water in the water tank is monitored in real time, and the low temperature required by water cooling is ensured.

Regarding the specific structure of the water-cooling clamp 300, in some embodiments of the present application, referring to fig. 2, the water-cooling clamp 300 is a two-half structure, and includes two sub water-cooling clamps 310 disposed oppositely, and each sub water-cooling clamp 310 is provided with a water containing cavity, a water inlet pipe 410 and a water outlet pipe 420.

The waterway circulation of each sub water-cooling clamp 310 is mutually independent, so that the check valve 100 is cooled by water simultaneously through two water containing cavities, which is beneficial to improving the cooling efficiency.

The two sub water-cooling clamps 310 jointly form a through space for placing the check valve 100, and each sub water-cooling clamp 310 is located on the outer peripheral side of the check valve 100 and symmetrically arranged, so that the cooling uniformity of the check valve 100 is improved.

Alternatively, the water inlet pipe 410 and the water outlet pipe 420 are oppositely disposed at both ends of the sub water-cooling clip 310, as shown in fig. 3.

With respect to the two-half type water-cooling clamp structure, in other embodiments, there may be no connection relationship (not shown) between the two sub water-cooling clamps 310, and each sub water-cooling clamp 310 is mounted on the outer circumferential side of the check valve 100 by a separate structure of a claw, a strap, or the like.

Another embodiment of the water-cooling clamp 300 is shown in fig. 4, and different from the two-half structure, the water-cooling clamp 300 may also be an integrated structure, the water-cooling clamp 300 is an integrated hollow cylinder structure with a single-side opening, and encloses a through space for installing the check valve 100, and the water-cooling clamp 300 has certain elasticity to allow the inner diameter of the through space to be increased, so as to facilitate the installation of the check valve 100, and can clamp the check valve 100.

The water containing cavity inside the integrated water-cooling clamp 300 can be divided into a plurality of mutually independent sub water containing cavities by the partition plates, and each sub water containing cavity is connected with a water inlet pipe 410 and a water outlet pipe 420, so that the cold water heat exchange efficiency is improved.
