Description

Technical Field

[0001] The utility model relates to the technical field of liquid level control, in particular to a double-cavity connecting pipe and a structural water pool. Background Art

[0002] like Figure 1 As shown, the fire protection system usually uses a structural pool, and the water supply pipe passes through the wall of the pool to enter the pool for water supply. According to relevant regulations of the construction industry, the waterproof requirements of the reinforced concrete pool wall are relatively high, and the water supply pipe needs to be pre-buried with a B-type flexible waterproof casing. However, before the water supply pipe enters the pool, a remote control liquid level float valve is usually set. The principle of the valve is to seal the liquid in the connecting pipe through the internal float height, thereby closing the float valve. Therefore, the connecting pipe and the pool water supply pipe need to pass through the pool wall. Usually, the external wing ring of the waterproof casing of the connecting pipe conflicts with the pool water supply pipe, making it impossible to install the casing on site, and the float is close to the outlet, the liquid level is disturbed, and the float position moves up and down frequently, causing the float guide valve to open or close frequently, and it cannot play its due role.

[0043] Embodiment 1

[0044] This embodiment discloses a double-lumen connecting tube, such as Figure 2 to Figure 6 As shown, the double-lumen connecting pipe 1 can at least be used as a partial water supply pipe of the structural pool, including:

[0045] A fluid channel 11 for fluid circulation, i.e., replenishing water to the structural pool through the fluid channel 11;

[0046] The connecting channel 12 is independent of the fluid channel 11 to allow the connecting pipe 2 of the float control device to pass through, that is, the connecting pipe 2 is at least partially hidden in the double-cavity connecting pipe through the connecting pipe 12.

[0047] The double-lumen connecting pipe of the utility model, by providing a connecting channel 12 for the connecting pipe 2 to pass through, avoids reserving or later manufacturing a hole and / or sleeve on the wall of the pool for the connecting pipe 2 to pass through. On the one hand, it avoids the risk of damaging the waterproof structure inside the structural pool, and on the other hand, it plays a role in protecting the connecting pipe 2.

[0048] Specifically, the fluid channel 11 includes a water inlet 111 and a water outlet 112, and the fluid channel 11 extends from the water inlet 111 to the water outlet 112. Preferably, the water inlet 111 and the water outlet 112 are respectively arranged at two ends of the double-cavity connecting tube 1, that is, the double-cavity connecting tube 1 includes a tube wall 11a that limits the fluid channel 11, and the water inlet 111 and the water outlet 112 are respectively surrounded at two ends of the tube wall 11a.

[0049] The connecting channel 12 includes a first connecting port 121 and a second connecting port 122, and the connecting channel 12 extends from the first connecting port 121 to the second connecting port 122. Preferably, the first connecting port 121 and the second connecting port 122 are disposed on the tube wall 11a of the double-lumen connecting tube.

[0050] According to an embodiment of the present invention, the fluid channel 11 is a cylindrical channel, that is, the tube wall 11a is in the shape of a hollow cylinder.

[0051] Preferably, the first connection port 121 and the second connection port 122 are arranged on the same side of the double-lumen connecting tube 1, that is, the first connection port 121 and the second connection port 122 are opened on the same side of the tube wall 11a, that is, the connection line between the first connection port 121 and the second connection port 122 is parallel to the center line AA of the fluid channel 11, and the center line of the fluid channel 11 overlaps with the center line of the double-lumen connecting tube.

[0052] Further preferably, the bottom wall of the connecting channel 12 is parallel to the center line AA of the fluid channel 11 .

[0053] The side wall of the connecting channel 12 is at least partially surrounded by the side wall of the fluid channel 11 (ie, the tube wall 11 a ), that is, the connecting channel occupies part of the space of the fluid channel 11 .

[0054] According to one embodiment of the present invention, the connecting channel 12 is located in the fluid channel 11, that is, the side wall of the connecting channel 12 extends from the first connecting port 121 through the fluid channel 11 to the second connecting port 122. Preferably, the connecting channel 12 is parallel to the center line AA of the fluid channel in the extension direction of the fluid channel.

[0055] According to another embodiment of the present invention, the connecting channel 11 is a groove provided on the wall of the double-cavity connecting tube, that is, part of the tube wall is recessed to form the connecting channel 11, and the depth of the groove is not less than the diameter of the connecting tube 2 to ensure that the connecting tube 2 can be embedded in the groove. Preferably, the bottom of the groove is parallel to the center line AA of the fluid channel.

[0056] It should be noted that the diameter of the connecting channel 12 is greater than the diameter of the connecting pipe 2 to ensure that the connecting pipe 2 can pass through the connecting channel 12 .

[0057] A connecting flange 13 is provided at one end of the double-chamber connecting pipe 1 to be detachably connected to the remote control float valve of the float control device. The connecting flange 13 is arranged at one end where the water inlet 111 is located, that is, the connecting flange 13 is arranged around the outside of the water inlet 111. The connecting flange 13 is provided with a plurality of flange holes 131, and the flange holes 131 are evenly arranged on the flange plate. In this embodiment, the flange plate of the connecting flange 13 is evenly provided with 8 flange holes.

[0059] The double-cavity connecting pipe of the utility model has a connecting pipe 2 that is extended from the double-cavity connecting pipe 1 and connected to the float pilot valve 3, so that the float pilot valve 3 is close to the outlet of the water supply pipe. As a result, when the length of the valve stem 4 remains unchanged, the float 5 is farther away from the outlet of the water supply pipe, which can reduce the frequent start and stop of the float pilot valve caused by the uneven water surface near the outlet of the water supply pipe.

[0060] The double-cavity connecting pipe of the utility model integrates the connecting pipe 2 on the double-cavity connecting pipe through the connecting channel, so that only a through hole needs to be opened on the wall of the pool and a sleeve is arranged on the through hole, which can effectively avoid the conflict between the sleeve of the water supply pipe and the sleeve of the connecting pipe.

[0061] Preferably, the double-lumen connecting pipe 1 is made of steel and is integrally formed. The flange is made of stainless steel to facilitate detachable connection.

[0069] Specifically, the flange 13 of the double-chamber connecting pipe 1 is detachably connected to the remote control float valve.

[0070] Preferably, in order to reduce the fluctuation caused by the water flow entering the pool cavity, the double-cavity connecting pipe 1 is provided with a bend 7 at one end of the water outlet, and the bend 7 bends toward the bottom of the pool cavity to reduce the distance between the outlet of the water supply pipe (at least including the double-cavity connecting pipe 1 and the bend 7) and the water surface.

[0071] Preferably, a sealing sleeve 8 is provided between the perforation 61 and the double-lumen connecting tube 1, which, on the one hand, protects the double-lumen connecting tube 1, and, on the other hand, improves the sealing effect of the water pool cavity.
