Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, and more specifically to a water distributor for fire fighting. Background Art

[0002] The water divider is a very commonly used device in the fire protection field. It is a device that divides the single stream of water coming from the water inlet into two streams and sends them to the fire scene for fire extinguishing. The water divider is used as a water supply and fire extinguishing device at the fire scene.

[0003] At present, a Chinese patent with announcement number CN206708459U discloses a fire water distributor, including a water inlet, two water outlets, two rotating handles, two pressure relief valves and two ball valves, wherein the one water inlet and the two water outlets are an integral structure, the two ball valves are respectively arranged in the two water outlets, the two rotating handles are respectively connected to the two ball valves, springs, balls and two steel columns are installed in the two rotating handles, the rotating handles, springs, balls and two steel columns together constitute a ball valve control mechanism, and the two pressure relief valves are installed on the two water outlets.

[0004] When using the fire-fighting water distributor, connect the water inlet to the water outlet of the fire pump, and then open the water distributor through the ball valve. At this time, the fire pump injects fire-fighting water into the water inlet, and then the fire-fighting water inside the water inlet is discharged to the outside through the water distributor. In the above-mentioned patent document, in order to discharge the water in the hose normally, a pressure relief valve is added. However, because the water supply pressure of the fire truck is too high, the pressure relief valve will fail during use and needs frequent maintenance and replacement. At the same time, there is no pressure gauge inside the existing water distributor, and it is impossible to know the pressure inside the water distributor at all times.

[0005] In view of the defects of the existing technology, a new type of fire-fighting water distributor is designed. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a water divider with a water pressure display which can effectively remove residual water in a water belt.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, which mainly include:

[0008] A fire-fighting water distributor comprises a main joint and a water distributor connected to the main joint, wherein a control ball valve is arranged inside the water distributor, and a rotating handle is connected to each of the control ball valves, and the opening and closing of the ball valve is controlled by the rotating handle; a one-way valve is arranged inside the main joint, and the flow direction of liquid inside the main joint is controlled by the one-way valve; and a pressure gauge is arranged between the one-way valve and the water distributor.

[0009] Preferably, two water diversion joints are provided at one end of the main joint, the two water diversion joints and the main joint form a Y shape, and the angle between the two water diversion joints is 30-35°.

[0010] Preferably, a mounting hole for a pressure gauge is provided at the middle angle of the water diversion joint, and the pressure gauge is connected to the mounting hole via threads.

[0011] Preferably, the pressure gauge is a mechanical water pressure gauge with a measuring range of 0-10Mpa.

[0012] Preferably, the main joint is configured as a quick-insert male joint, and the water diversion joint is configured as a quick-insert female joint.

[0013] Preferably, the quick-plug connector is a DN40 forest fire protection interface, and the connector can be rotated 360°.

[0014] It can be seen from the above technical solution that compared with the prior art, the utility model provides an improved water manifold, which is mainly used for fire water manifolds. A one-way valve and a pressure gauge are arranged inside the water manifold, which can quickly know the water pressure in the water manifold and effectively discharge the residual water in the water manifold. The utility model has a simple structure, reliable function and low maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
