Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a water-saving fire sprinkler head. Background Technology

[0002] Traditional fire sprinklers typically employ a fixed orifice design or a single regulating valve, making it difficult to dynamically adjust the water flow according to the size of the fire, easily leading to water waste. Some existing technologies achieve flow control by replacing nozzles or manually adjusting valves, but the adjustment efficiency is low, requiring shutdown for component replacement or manual operation, delaying firefighting opportunities; they also cannot quickly respond to different fire situation needs, lacking flexibility. Therefore, there is an urgent need for a water-saving fire sprinkler that can quickly switch flow modes. Utility Model Content

[0003] The purpose of this invention is to provide a water-saving fire sprinkler head that solves the problems of low adjustment efficiency and insufficient flexibility of traditional fire sprinkler heads.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] A water-saving fire sprinkler head includes:

[0006] The transfer pipe has an assembly hole running through its middle section perpendicular to the axis; the two ends of the transfer pipe are respectively connected to a nozzle and a water supply pipe.

[0007] The assembly is slidably disposed in the assembly hole and fits against the side wall of the assembly hole; the assembly is also provided with several water-saving valves with different orifice diameters, so that when the assembly slides along the assembly hole, the different water-saving valves are respectively connected to the corresponding pipe openings of the transfer pipe.

[0008] The assembly is a ring-shaped assembly ring.

[0009] The inner wall of the assembly ring is provided with a toothed groove; a gear driven by a motor is provided between the outer wall of the transfer tube and the inner wall of the assembly ring, and the gear meshes with the toothed groove.

[0010] The transfer pipe is equipped with sealing mechanisms at both ends.

[0011] The sealing mechanism includes an installation sleeve, a telescopic rod, a pressure ring, and a sealing ring. The installation sleeve is connected to both ends of the transfer pipe, and a telescopic rod is provided on its outer side wall. An annular sliding groove is provided inside the end of the transfer pipe, which passes through the assembly hole. A pressure ring is slidably disposed in the sliding groove. The movable end of the telescopic rod passes through the end of the transfer pipe, extends into the sliding groove, and is connected to one side of the pressure ring. A sealing ring is provided on the side of the pressure ring near the assembly hole. The telescopic rod drives the pressure ring to move along the sliding groove toward the assembly hole, so that the sealing ring on one side of the pressure ring extends out of the sliding groove and contacts the surface of the assembly.

[0012] The surface of the fitting has an annular sealing groove around the water-saving valve that corresponds to the sliding groove; when the telescopic rod drives the pressure ring to move, the sealing ring extends out of the sliding groove and is placed in the sealing groove.

[0013] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0014] 1. This utility model provides a water-saving fire sprinkler head that achieves multi-level flow regulation by switching water-saving valves of different orifice diameters through a sliding assembly. It can accurately control the water volume according to the fire situation and reduce ineffective water spraying.

[0015] 2. It adopts a ring assembly ring and gear drive structure, which supports electric rapid adjustment and can switch flow modes without stopping the machine, thus improving the response speed;

[0016] 3. A sealing mechanism is provided, which drives the pressure ring and sealing ring to press the sealing groove through the telescopic rod. This ensures that after the assembly is adjusted, the annular fit design of the sealing groove and sealing ring enhances the sealing surface fit and prevents high-pressure water leakage.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a water-saving fire sprinkler head includes a transfer pipe 1 and an assembly. The two ends of the transfer pipe 1 are connected to a nozzle 5 and a water supply pipe, respectively. Water is sequentially transported through the water supply pipe and the transfer pipe 1 to the nozzle 5 and sprayed out. To achieve water saving, the speed of water flow through the transfer pipe 1 needs to be changed. Therefore, assembly holes 101 are provided on both sides of the transfer pipe 1, and the assembly is slidably disposed in the assembly holes 101. Several water-saving valves 201 with different orifice diameters are provided on the assembly. By sliding the assembly in the assembly holes 101, different water-saving valves 201 are placed inside the transfer pipe 1 and connected to the nozzle 5 and the water supply pipe at both ends of the transfer pipe 1. This results in different water flow rates when water flows through the water-saving valves 201 with different orifice diameters, thereby achieving flow control and water saving.

[0025] like Figure 1 As shown, in one embodiment, the assembly is a ring-shaped assembly ring 2. When the assembly moves along the assembly hole 101, the assembly ring 2 actually rotates around its axis. By manually rotating the assembly ring 2, the water-saving valves 201 with different hole diameters can be switched.

[0026] In another embodiment, a motor 304 is used to control the rotation of the assembly ring 2. A toothed groove 203 is provided on the inner wall of the assembly ring 2. A gear 302, controlled by the motor 304, meshes with the toothed groove 203 on the inner side of the assembly ring 2, thereby achieving motor 304 control. The position of the gear 302 relative to the transfer tube 1 needs to be fixed. Therefore, a mounting plate 301 is provided on the outer wall of the transfer tube 1 near the axis of the assembly ring 2. The gear 302 is rotatably mounted on the mounting plate 301. A support plate 303 is provided on one side of the mounting plate 301 for mounting and fixing the motor 304, and the shaft of the motor 304 is connected to the gear 302 to drive its rotation. By controlling the motor 304 to drive the gear 302 to rotate, the rotation of the assembly ring 2 can be controlled.

[0027] like Figure 2 and 4As shown, in one embodiment, sealing mechanisms are provided at both ends of the transfer pipe 1, including an installation sleeve 401, a telescopic rod 402, a pressure ring 104, and a sealing ring 105. The installation sleeve 401 is connected to both ends of the transfer pipe 1, so that the nozzles 5 and the water supply pipes at both ends of the transfer pipe 1 are connected to the transfer pipe 1 through the installation sleeve 401. Several telescopic rods 402 are arranged around the outer wall of the installation sleeve 401. An annular sliding groove 102 is provided inside the end of the transfer pipe 1, which passes through the assembly hole 101. The pressure ring 104 is slidably arranged in the sliding groove 102. By controlling the movement of the pressure ring 104 in the sliding groove 102, the pressure ring 104 can extend out of the sliding groove 102 and abut against the assembly.

[0028] The sliding groove 102 is also provided with a through hole at the end near the transfer tube 1 and away from the assembly ring 2. The telescopic end of the telescopic rod 402 of the pressure plate passes through the through hole into the sliding groove 102 and is connected to the pressure plate. When the telescopic end of the telescopic rod 402 extends or retracts, it can drive the pressure ring 104 to move along the sliding groove 102.

[0029] A sealing ring 105 is provided on the side of the pressure ring 104 near the assembly hole 101; when the telescopic rod 402 drives the pressure ring 104 to move along the sliding groove 102 toward the assembly hole 101, the sealing ring 105 on one side of the pressure ring 104 extends out of the sliding groove 102 and contacts the surface of the assembly, thereby greatly reducing the risk of water leaking out from the gap between the assembly ring 2 and the assembly hole 101.

[0030] In this embodiment, the telescopic rod 402 is preferably an electrically controlled telescopic rod 402, which is a common mechanical structure in the art, and will not be described in detail in this embodiment.

[0031] In one embodiment, to further enhance the sealing performance between the assembly ring 2 and the transfer pipe 1, the surface of the assembly is provided with an annular sealing groove 202 around the water-saving valve 201, which corresponds to the sliding groove 102; when the telescopic rod 402 drives the pressure ring 104 to move, the sealing ring 105 extends out of the sliding groove 102 and is placed in the sealing groove 202, which can further enhance the sealing performance.

[0032] The working principle of this embodiment is as follows:

[0033] This utility model discloses a water-saving fire sprinkler head. First, the sealing ring 105 is slid until the appropriate water-saving valve 201 corresponds to the pipe opening of the transfer pipe 1. Then, the telescopic rod 402 drives the pressure ring 104 to move along the sliding groove 102 toward the assembly hole 101, so that the sealing ring 105 extends out of the sliding groove 102 and is placed in the sealing groove 202. Then, the water valve is opened to spray water. When the water volume needs to be adjusted, the water valve is closed, and the sealing ring 105 is separated from the sealing groove 202. Then, the sealing ring 105 is rotated to the appropriate water-saving valve 201, and then the above steps are repeated to spray water.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
