Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fire-fighting branch water pipe pressure boosting, in particular to a water flow booster for fire-fighting branch water pipes. Background Art
[0002] The best time to extinguish a fire is usually in the early stages of a fire, especially within three minutes of the fire. During this period, the fire is weak and the area is small. If effective firefighting measures can be taken in time, the fire can be effectively controlled in the early stages, thereby minimizing the losses. Therefore, various fire warning and fire extinguishing devices are used in life.
[0003] The sprinkler system is a fire extinguishing device and is a widely used fixed fire fighting facility. When a fire needs to be extinguished, the sprinkler system valve is opened to allow water in the water pipe to gush out to extinguish the fire. However, when the water pressure is low (caused by high floors or other reasons), the fire extinguishing effect will be greatly reduced, resulting in threats to property and life. Summary of the invention
[0004] The utility model aims to provide a water flow booster for fire fighting branch water pipes to solve the problems raised in the above-mentioned background technology.
[0005] The purpose of this utility model is to adopt the following technical solutions to achieve:
[0006] A water flow booster for a fire branch water pipe according to the utility model comprises a shell for connecting a water pipe, a water inlet end and a water outlet end protruding from the shell, an annular groove is provided inside the shell, the annular groove is provided with a central channel, a retaining edge is provided at one end of the central channel, the water inlet end is located below the retaining edge, a sealing baffle is slidably provided on the outer side of the central channel, the inner ring circle diameter of the sealing baffle is smaller than the outer ring circle diameter of the retaining edge, sealing rings are provided on the outer side and the inner side of the inner ring circle of the sealing baffle, the sealing baffle and the annular groove form a sealing cavity, and the sealing cavity contains air;
[0007] A driving device is arranged outside the shell, an output shaft of the driving device penetrates into the shell, and a spiral blade is arranged at the end thereof.
[0008] By means of the above technical solution, the utility model has the following advantages:
[0009] Water flow pressurization is achieved by setting up a sealed chamber and spiral blades: the air in the sealed chamber is compressed by water to generate an extrusion force on the water, and the water flow is pressurized under the action of the spiral blades. The device is not only simple in structure, low in cost, but also easy to install.
[0010] Furthermore, the drainage direction of the water outlet is parallel to the axial direction of the sealing baffle. Sealing rings are arranged on the outer side of the outer ring circle and the inner side of the inner ring circle of the sealing baffle, and the sealing rings are made of flexible sealing materials.
[0011] Advantages: When the drainage direction of the water outlet is parallel to the axial direction of the sealing baffle, the direction of the extrusion force of the air on the water flow is consistent with the drainage direction of the water outlet, which can make the water flow faster and the pressurization effect better.
[0012] Furthermore, a normally closed inflation hole is provided outside the sealed cavity.
[0013] Advantages: After the above-mentioned water flow booster is used for a long time, air may be lost. When the air in the sealed cavity is insufficient, air can be added through the inflation hole to achieve the best boosting state.
[0014] Furthermore, both the water inlet and the water outlet are provided with threads.
[0015] Advantages: The thread setting makes the water pipe installation more convenient.
[0016] Furthermore, the sealing ring is made of a flexible sealing material.
[0017] Advantages: The sealing ring can effectively prevent the loss of air in the sealing cavity, which results in insufficient air compression, reduced squeezing pressure exerted by the air on the water, and poor pressurization effect; the use of flexible sealing materials can better prevent air loss.
[0018] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

[0022] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the need for some of these specific details. The following description of the embodiment is only to provide a better understanding of the utility model by showing an example of the utility model. In the accompanying drawings and the following description, at least part of the known and prior art is not shown to avoid unnecessary ambiguity to the utility model; and, for clarity, the size and shape of the part may be exaggerated. The features or characteristics described below can be combined in one or more embodiments in any suitable manner. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or quantity.
[0023] The utility model provides Figure 1 The water flow booster for a fire branch water pipe shown in the figure comprises a shell 1 for connecting a fire branch water pipe, an annular groove is provided inside the shell 1, a central channel 3 is provided in the annular groove, a retaining edge 301 extending outward is provided at one end of the central channel 3, a sealing baffle 4 is slidably provided on the outer side of the central channel 3, the inner ring diameter of the sealing baffle 4 is smaller than the outer ring diameter of the retaining edge 301 (the retaining edge 301 plays a limiting role, which can prevent the sealing baffle 4 from falling off from the central channel 3, resulting in air loss and boost failure), and the sealing baffle 4 forms a seal with the annular groove The sealed cavity 2 contains air, and a normally closed inflation hole 6 is opened outside the sealed cavity 2 (after the water flow booster is used for a long time, the air in the sealed cavity 2 may be insufficient. At this time, the inflation hole 6 can be opened to add air to the sealed cavity 2). A sealing ring 5 is arranged on the outer side of the outer ring circle and the inner side of the inner ring circle of the sealing baffle 4, and the sealing ring 5 is made of flexible sealing material (such as rubber). The sealing ring 5 can effectively prevent the air in the sealed cavity 2 from being lost, resulting in insufficient air being compressed, the squeezing pressure exerted by the air on the water becoming smaller, and the pressurization effect becoming worse.
[0024] A driving device 7 is arranged outside the housing 1. The output shaft of the driving device 7 penetrates into the housing 1 and a spiral blade 8 is arranged at the end. After the driving device 7 is started, the spiral blade 8 starts to rotate and can pressurize the water.
[0025] The water flow booster for the fire branch water pipe also includes a water inlet 9 and a water outlet 10. Both the water inlet 9 and the water outlet 10 protrude from the outside of the outer shell 1, and the water inlet 9 is located below the retaining edge 301, which can prevent the water flowing out of the water inlet 9 from directly flowing into the sealed cavity 2, causing the sealed cavity 2 to lose the boosting effect; the drainage direction of the water outlet 10 is parallel to the axial direction of the sealing baffle 4 (the best state is to coincide with the axial direction of the sealing baffle 4), and the drainage direction is consistent with the direction of air pressure, which can make the water flow faster and the boosting effect better. Furthermore, the water inlet 9 and the water outlet 10 are both provided with threads to facilitate the installation and disassembly of the fire branch water pipe. In other embodiments of the utility model, the connection between the water inlet 9 and the water outlet 10 can also be achieved by other means, such as fixing with a clamp.
[0026] The specific operation of a water flow booster for a fire branch water pipe is as follows:
[0027] Ready-to-use state: open the water inlet pipe valve, close the drain pipe valve, so that the water level in the housing 1 rises. Under the action of water, the sealing baffle 4 slides in the direction away from the baffle edge 301 until the pressure applied by the air in the sealing chamber 2 to the sealing baffle 4 is equal to the pressure applied by the water to the sealing baffle 4, and a balanced state is reached.
[0028] Usage status: open the drain pipe valve, at this time the flow rate of the drain pipe is the same as that of the water inlet pipe; power on the drive device 7, the spiral blade 8 starts to rotate, and the air in the sealed chamber 2 is always subjected to extrusion pressure, and under the action of the spiral blade 8 and the air in the sealed chamber 2, a pressurization effect is achieved.
[0029] After use, close the drain pipe valve to restore to the standby state; after long-term use, the inflation hole 6 should be opened to fill enough air into the sealing cavity 2 to prepare for the next use.
[0030] The above is only a preferred embodiment of the present invention. Any technician familiar with the profession, without departing from the scope of the technical solution of the present invention, makes any simple modifications, equivalent changes and modifications to the above embodiments based on the technical essence of the present invention, which still fall within the scope of the technical solution of the present invention.
