Description

Technical Field

[0001] This utility model relates to a fire valve, and more particularly to an adjustable fire valve. Background Technology

[0002] A fire valve is a valve device installed on a pipeline. It can be used to control the flow of water in the pipeline. There are many types of fire valves available, such as ball valves and gate valves.

[0003] During routine patrols, security personnel discovered that existing fire valves have at least the following defects: fire valves do not have a filtering function. During long-term use, there may be particulate matter such as rust and sand in the water. If this matter accumulates near the fire valve through the pipes, some impurities will accumulate near the fire valve. Over time, the fire valve will be difficult to open and close, resulting in a long maintenance process and unnecessary trouble. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable fire valve to solve the technical problems existing in the prior art.

[0005] According to one aspect of the present invention, an adjustable fire valve is disclosed, comprising a valve body and a filter device disposed on one side of the valve body. The valve body is provided with an adjustment device, which can adjust the opening and closing degree of the valve body to adjust the flow rate of the pipeline. The filter device is located on the water inlet side of the valve body and can filter the water on the water inlet side.

[0006] In some embodiments, the filtration device includes a mounting frame and a filter screen, with the filter screen disposed on the mounting frame. Thus, the filter screen can be secured within the pipe by the mounting frame.

[0007] In some embodiments, the mounting bracket includes a first fixing member and a second fixing member. The first fixing member is disposed on the inner wall of the pipe of the valve body, and the filter screen is disposed between the first fixing member and the second fixing member. The second fixing member can be connected to the filter screen and the first fixing member by screws. Thus, the filter screen can be fixed between the first fixing member and the second fixing member. During use, the filter screen can filter impurities in the water, and the second fixing member and the filter screen can be removed by unscrewing the screws.

[0008] In some embodiments, a retaining clip is provided in the pipe, a first fastener is fixed to the retaining clip, and the first fastener and the retaining clip cannot be disassembled.

[0009] In some embodiments, both the first and second fixing members are annular, and each of the first, filter, and second fixing members has screw holes. Screws can pass through the screw holes of the second fixing member, the filter, and the first fixing member in sequence. Thus, the first fixing member, the filter, and the second fixing member can be connected together by screws.

[0010] In some embodiments, both the first and second fixing members are provided with annular grooves, and annular protrusions are provided on both sides of the corresponding position of the outer ring of the filter screen. The annular protrusions can be engaged in the annular grooves. Thus, the outer ring of the filter screen can be engaged in the annular grooves of the first and second fixing members through the annular protrusions.

[0011] In some embodiments, a connecting flange is provided on the outer wall of the inlet end of the valve body, through which it is connected to an adjacent pipe. Thus, the inlet end of the valve body and the adjacent pipe can be connected via the connecting flange.

[0012] In some embodiments, the valve body includes a valve body, a connecting rod, and a bracket. The valve body is a ball valve, and the connecting rod is connected to one end of the ball valve. The connecting rod can drive the ball valve to rotate to adjust the size of the connection between the ball valve's orifice and the pipeline.

[0013] In some implementations, there are two filters, positioned side by side. The left filter is secured to the right filter by an annular protrusion, and both filters are held in place by annular grooves. Therefore, using two filters provides better filtration, and even if one filter fails, it can still perform its filtering function.

[0014] The beneficial effects of this utility model are as follows: This utility model is generally used in firefighting operations. Since the water requirements for firefighting are not high, the water sometimes contains particulate matter such as rust and sand. This utility model includes a valve body and a filter device located on one side of the valve body. The filter device can filter out impurities in the water, preventing them from accumulating at the valve body. Furthermore, the valve body in this utility model can adjust the water flow and shut-off. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Figures 1-3 The diagram schematically illustrates the structure of an adjustable fire valve according to one embodiment of the present invention.

[0023] like Figures 1-3 As shown, an adjustable fire valve includes a valve body 1 and a filter device 2 installed on one side of the valve body 1.

[0024] An adjustment device can be installed on the valve body 1. The adjustment device can adjust the opening and closing degree of the valve to adjust the flow rate of the pipe 4. The filter device 2 is located on the water inlet side of the valve body 1 (the pipe 4 can form the water inlet of the valve body 1). The filter device 2 can filter the water on the water inlet side. The filter device 2 can filter out impurities such as rust and sand in the water, preventing the accumulation of impurities such as rust and sand in the valve body 1 and affecting the use of the valve body 1.

[0025] like Figure 2 As shown, the filter device 2 in this embodiment includes a fixed frame and a filter screen 21. The filter screen 21 can be installed on the fixed frame, and the filter screen 21 can be installed in the pipe 4 through the fixed frame.

[0026] like Figure 2As shown, the fixing frame includes a first fixing member 22 and a second fixing member 23. The first fixing member 22 is fixedly installed on the inner wall of the pipe 4. The filter screen 21 is installed between the first fixing member 22 and the second fixing member 23. The second fixing member 23 and the filter screen 21 can be removed to replace the filter screen 21 and clean the filtered rust, sand and other impurities.

[0027] To securely install the first fastener 22 onto the inner wall of the pipe 4, a fixing buckle 41 can be installed on the inner wall of the pipe 4. The fixing buckle 41 is also ring-shaped. The first fastener 22 can be welded to the fixing buckle 41, therefore, the first fastener 22 and the fixing buckle 41 cannot be separated. The first fastener 22 acts as a base, meaning that the filter screen 21 and the second fastener 23 can be installed on the first fastener 22.

[0028] In this embodiment, both the first fixing member 22 and the second fixing member 23 are annular. The first fixing member 22, the filter screen 21, and the second fixing member 23 are connected by screws. Specifically, screw holes are integrally formed on both the first fixing member 22 and the second fixing member 23, and screw holes are also provided at corresponding positions on the filter screen 21. Screws can be installed as follows: Figure 1 As shown, screws are sequentially inserted into the screw holes of the second fixing member 23, the screw hole of the filter screen 21, and the screw hole of the first fixing member 22, and then the three are fixed together. The shapes of the first fixing member 22 and the second fixing member 23 are consistent with the inner wall of the pipe. In other embodiments, the shapes of the first fixing member 22 and the second fixing member 23 can be changed according to the shape of the inner wall of the pipe 4.

[0029] like Figure 2 and Figure 3 As shown, both the first fixing member 22 and the second fixing member 23 have annular grooves 233 integrally formed, and the outer ring of the filter screen 21 has annular protrusions 211 integrally formed on both sides at the corresponding positions. The annular protrusions 211 can be locked in the annular grooves 233, and the outer ring of the filter screen 21 can be locked in the annular grooves 233 through the annular protrusions 211 (e.g., Figure 1 and Figure 2 As shown, the left annular protrusion 211 of the filter screen 21 can be engaged in the annular groove 233 of the first fixing member 22, and the right annular protrusion 211 of the filter screen 21 can be engaged in the annular groove 233 of the second fixing member 23. The annular protrusion 211 and the annular groove 233 can both serve as positioning tools and facilitate the connection of the first fixing member 22, the filter screen 21, and the second fixing member 23 together.

[0030] like Figure 1As shown, a connecting flange 3 is fixedly connected to the outer wall of the water inlet end of the valve body 1. The connecting flange 3 is connected to the adjacent pipe 4. The connecting flange 3 can connect the water inlet end of the valve body 1 and the adjacent pipe 4. The connecting flange 3 can be fixed by bolts or other means.

[0031] like Figure 1 As shown, the valve body 1 includes a valve body 11, a connecting rod 12, and a bracket 13. The valve body 11 is a ball valve, and the connecting rod 12 is connected to one end of the ball valve. The connecting rod 12 can drive the ball valve to rotate to adjust the connection between the ball valve's orifice and the pipe 4. In other embodiments, the valve body 1 can be an electric ball valve or an electric gate valve. Regardless of the type of valve body 1, it is sufficient as long as it can control the water flow.

[0032] In other embodiments, such as Figure 4 As shown, there are two filters 211, positioned side by side. The left filter 211 is secured to the right filter 211 by an annular protrusion 211, and both filters are secured in annular grooves 233 by the same annular protrusion 211. Specifically, the left side of the left filter 211 has an annular protrusion 211, which secures it in the annular groove 233 of the first fixing member 22. Similarly, the right side of the right filter 211 is secured in the annular groove 233 of the second fixing member 23 by the same annular protrusion 211. Using two filters provides a better filtration effect, and even if one filter is damaged, it can still perform its filtering function.

[0033] This invention is generally used in firefighting operations. Since the water used in firefighting operations sometimes contains particulate matter such as rust and sand, this invention includes a valve body 1 and a filter device 2 located on one side of the valve body 1. The filter device 2 can filter out impurities from the water, preventing them from accumulating in the valve body 1. Furthermore, the valve body in this invention can adjust the water flow and shut-off.

[0034] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
