Description

Water-saving fire control shower nozzle Technical Field The utility model relates to the technical field of fire-fighting equipment, in particular to a water-saving fire-fighting nozzle. Background The traditional fire-fighting spray head usually adopts a fixed aperture design or a single regulating valve, is difficult to dynamically regulate the water quantity according to the fire intensity, and easily causes water resource waste. The flow control is realized by replacing the nozzle or the manual regulating valve in part of the prior art, but the regulating efficiency is low, the parts are required to be replaced by stopping the machine or the manual operation is required, the fire extinguishing time is delayed, the requirements of different fires cannot be responded quickly, and the flexibility is insufficient. Therefore, there is a need for a water-saving fire sprinkler that can quickly switch flow modes. Disclosure of utility model The utility model aims to provide a water-saving fire-fighting nozzle, which solves the problems of low adjusting efficiency and insufficient flexibility of the traditional fire-fighting nozzle. The embodiment of the utility model is realized by the following technical scheme: A water-saving fire sprinkler comprising: The middle part of the transfer pipe is communicated with an assembly hole in the direction perpendicular to the axis, and two ends of the transfer pipe are respectively connected with the nozzle and the water supply pipe; The assembly part is arranged in the assembly hole in a sliding manner and is attached to the side wall of the assembly hole, and a plurality of water-saving valves with different apertures are further arranged on the assembly part, so that when the assembly part slides along the assembly hole, the different water-saving valves are correspondingly communicated with the pipe orifice of the transfer pipe respectively. The fitting is an annular fitting ring. The inner side wall of the assembly ring is provided with a tooth slot, a gear driven by a motor is arranged between the outer side wall of the transfer pipe and the inner side wall of the assembly ring, and the gear is meshed with the tooth slot. And sealing mechanisms are respectively arranged at two ends of the transfer pipe. The sealing mechanism comprises a mounting pipe sleeve, a telescopic rod, a compression ring and a sealing ring, wherein the mounting pipe sleeve is respectively connected to two ends of a transfer pipe, the telescopic rod is arranged on the outer side wall of the mounting pipe, an annular sliding groove penetrating through an assembly hole is arranged in the end portion of the transfer pipe, the compression ring is arranged in the sliding groove in a sliding mode, the movable end of the telescopic rod penetrates through the end portion of the transfer pipe to extend into the sliding groove and is connected to one side of the compression ring, the sealing ring is arranged on one side, close to the assembly hole, of the compression ring, and the telescopic rod drives the compression ring to move towards the assembly hole along the sliding groove, so that the sealing ring on one side of the compression ring extends out of the sliding groove and contacts with the surface of an assembly part. The surface of the assembly part is provided with an annular sealing groove which is arranged around the water-saving valve and corresponds to the sliding groove, and when the telescopic rod drives the compression ring to move, the sealing ring extends out of the sliding groove and is matched with the sealing groove. The technical scheme of the embodiment of the utility model has at least the following advantages and beneficial effects: 1. According to the water-saving fire sprinkler, the water-saving valves with different apertures are switched through the sliding assembly, so that the flow rate is regulated in multiple stages, the water quantity can be accurately controlled according to fire conditions, and ineffective water spraying is reduced; 2. The annular assembly ring and gear driving structure is adopted, electric rapid adjustment is supported, the flow mode can be switched without stopping, and the response speed is improved; 3. Be provided with sealing mechanism, compress tightly the seal groove through telescopic link drive clamping ring and sealing ring, ensure the assembly part and adjust the back, utilize the annular cooperation design of seal groove and sealing ring, strengthen sealed face laminating degree, prevent high-pressure rivers seepage.
