Description

Technical Field

[0001] This utility model relates to the field of elbow technology, specifically to a gas filter elbow. Background Technology

[0002] Elbows are common pipe fittings primarily used to change the direction of fluid transport and achieve a smooth transition between two pipe sections. They are widely used in pipeline layouts for various fluid transport systems, including those carrying water, oil, and gas. Gas pipelines typically transport flammable gases such as natural gas and liquefied petroleum gas, and their operating conditions are characterized by high pressure, stringent safety requirements, and the presence of invisible but high-risk media.

[0003] When gas flows through a bend, the abrupt change in flow direction causes eddies and boundary layer separation on the inner wall of the bend, resulting in a decrease in local velocity and an increase in pressure loss. Although the gas itself does not contain solid particles, during long-term operation, trace amounts of condensate, oil, corrosion products, or debris from the pipe's inner wall may accumulate in areas of greater curvature and lower velocity at the bend. With prolonged use, this accumulation of impurities can reduce the flow cross-section, decrease gas delivery efficiency, and even cause pipe blockage, posing safety hazards. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a gas filter elbow to solve the problem that the existing elbows suffer from reduced flow cross-section due to impurity accumulation, resulting in decreased gas transmission efficiency, which in turn causes pipeline blockage and poses safety hazards.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A gas filter elbow includes an elbow body, with a horizontal pipe and a vertical pipe fixedly connected to the inner sides of both ends of the elbow body, respectively; an end cap, which is detachably installed on the side of the elbow body, and the inner diameter of the end cap is larger than the inner diameter of the horizontal pipe; a filter element, which is disposed inside the horizontal pipe, and the end face of the filter element is flush with the end face of the elbow body at the end of the horizontal pipe; and a limiting member, which is used to position the filter element, and the two ends of the limiting member are fixedly connected to the inner wall of the end cap and the end face of the filter element, respectively, and the limiting member abuts against the inner wall of the elbow body. The limiting member can abut against the inner wall of the elbow body, and the limiting member can limit the filter element.

[0006] In this way, the fluid flows from the horizontal pipe to the elbow body. After flowing a certain distance, the fluid comes into contact with the filter element inside the horizontal pipe. The filter element can filter the fluid and reduce the impurities carried by the fluid. The filter element is made of stainless steel, which can resist the corrosion of impurities carried by the fluid. The filtered fluid continues to flow through the elbow body to the vertical pipe. The filter element is subjected to the pressure of the fluid, and the limiting component limits the filter element to maintain its stability. During the flow, the end face of the filter element remains flush with the end face of the elbow body connected to the horizontal pipe to reduce obstruction to the fluid and maintain smooth fluid flow. After filtration is completed, staff can remove the end cap, take out the limiting component and filter element that are fixedly connected to the end cap, and clean the filter element directly. This structure can reduce the impurities carried by the fluid, thereby reducing the possibility of pipe blockage or reduced flow rate, and at the same time, it is convenient for staff to clean impurities directly.

[0007] Furthermore, the limiting component consists of a U-shaped elastic steel ring and a bent portion connected to both ends of the elastic steel ring. The center point of the elastic steel ring is fixedly connected to the inner wall of the end cap. The bent portion abuts against one end face of the elbow body connected to the horizontal pipe. The end of the bent portion is fixedly connected to the filter element.

[0008] In this way, pressure is applied to the filter element during fluid flow, which in turn applies pressure to the bend. After being pressed, the bend abuts against the inner wall of the elbow body. The center point of the elastic steel ring is fixedly connected to the inner wall of the end cap. After being pressed, the elastic steel ring can withstand most of the pressure, reducing the pressure on the bend. With this structure, the limiting component can maintain the limiting of the filter element and improve the stability of the filter element.

[0009] Furthermore, a sealing gasket is provided between the bend and the end face of the horizontal pipe, thereby reducing the fluid passing through the gap between the bend and the end face of the horizontal pipe, and thus reducing the possibility of impurities accumulating and clogging the pipe.

[0010] Furthermore, the filter element has a circular end face, a mesh-like overall structure, a filter element precision of 5-10μm, and a filter element specification that is compatible with the horizontal pipe. This improves the filtration effect on impurities carried by the fluid and reduces the possibility of impurities accumulating and clogging the pipe.

[0011] Furthermore, multiple sealing rings are evenly arranged on the outer side of the end cap, and the sealing rings abut against the inner wall of the elbow body, thereby improving the sealing effect of the end cap and reducing the possibility of end cap leakage.

[0012] Furthermore, the effective length of the horizontal pipe is a multiple of the nominal diameter, thereby improving the stability of the fluid medium flow velocity.

[0013] Furthermore, both the horizontal and vertical pipes are fixedly installed with tongue and groove flanges at their ends, thereby enabling a stable connection between the horizontal and vertical pipes and improving the sealing performance of the connection.

[0014] Furthermore, the inner and outer surfaces of the elbow body are electrophoretically coated with acrylic resin, and both the elbow body 1 and the end cap 2 are made of aluminum alloy, thereby improving the corrosion resistance of the elbow body 1.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model can reduce impurities carried by fluids, thereby reducing the possibility of pipe blockage or reduced flow rate; 2. This utility model allows workers to directly clean the inside of the pipe; 3. This invention can improve the stability of fluid medium flow rate. Attached Figure Description

Tongue and groove flange. Detailed Implementation

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] Example: like Figures 1-4As shown, the gas filter elbow of this utility model includes an elbow body 1, with a horizontal pipe 101 and a vertical pipe 102 fixedly connected to the inner sides of both ends of the elbow body 1, respectively; an end cap 2, which is detachably installed on the side of the elbow body 1, specifically, the end cap 2 is set facing the end face of the horizontal pipe 101, and the inner diameter of the end cap 2 is larger than the inner diameter of the horizontal pipe 101; a filter element 3, which is set inside the horizontal pipe 101, and the end face of the filter element 3 is flush with the end face of one end of the elbow body 1 connected to the horizontal pipe 101; and a limiting member 4, which is used to position the filter element 3, with both ends of the limiting member 4 fixedly connected to the inner wall of the end cap 2 and the end face of the filter element 3, respectively, and the limiting member 4 abuts against the inner wall of the elbow body 1.

[0020] In this way, the fluid flows from the horizontal pipe 101 to the elbow body 1. After flowing a certain distance, the fluid comes into contact with the filter element 3 inside the horizontal pipe 101. The filter element 3 can filter the fluid and reduce the impurities carried by the fluid. The filter element 3 is made of stainless steel, which can resist the corrosion of impurities carried by the fluid. The filtered fluid continues to flow through the elbow body 1 to the vertical pipe 102. The filter element 3 is subjected to pressure from the fluid, and the limiting member 4 limits the filter element 3 to maintain its stability. Specifically, the limiting member 4 can abut against the inner wall of the elbow body 1 to fix its own position. The two ends of the limiting member 4 are respectively fixed to the inner wall of the end cap 2 and the filter element 3, so that the limiting member 4 can limit the filter element 3. During the flow, the end face of the filter element 3 is kept flush with the end face of the elbow body 1 connected to the horizontal pipe 101 to reduce obstruction to the fluid and maintain smooth fluid flow. After filtration is completed, staff can remove the end cap 2, take out the limiting piece 4 and filter element 3 that are fixedly connected to the end cap 2, and clean the filter element 3 directly. This structure can reduce the impurities carried by the fluid, thereby reducing the possibility of pipe blockage or reduced flow rate, and at the same time, it is convenient for staff to clean impurities directly.

[0021] The limiting component 4 is divided into a U-shaped elastic steel ring 401 and a bent part 402 connected to both ends of the elastic steel ring 401. The center point of the elastic steel ring 401 is fixedly connected to the inner wall of the end cap 2. The bent part 402 abuts against one end face of the elbow body 1 of the horizontal pipe 101. The end of the bent part 402 is fixedly connected to the filter element 3.

[0022] In this way, during the fluid flow, pressure is applied to the filter element 3, which in turn applies pressure to the bend 402. After being pressed, the bend 402 abuts against the inner wall of the elbow body 1. The center point of the elastic steel ring 401 is fixedly connected to the inner wall of the end cap 2. After being pressed, the elastic steel ring 401 can withstand most of the pressure, reducing the pressure on the bend 402. With this structure, the limiting member 4 can maintain the limiting of the filter element 3, improving the stability of the filter element 3.

[0023] A sealing gasket 5 is provided between the bend 402 and the end face of the horizontal pipe 101, thereby reducing the fluid passing through the gap between the bend 402 and the end face of the horizontal pipe 101, and thus reducing the possibility of impurities accumulating and clogging the pipe.

[0024] The filter element 3 has a circular end face and an overall mesh-like structure. The filter element 3 has a precision of 5-10μm and its specifications are compatible with the horizontal pipe 101. This improves the filtration effect on impurities carried by the fluid and reduces the possibility of impurities accumulating and clogging the pipe.

[0025] Multiple sealing rings 201 are evenly arranged on the outer side of the end cap 2. The sealing rings 201 abut against the inner wall of the elbow body 1, thereby improving the sealing effect of the end cap 2 and reducing the possibility of gas leakage from the end cap 2.

[0026] The effective length of the horizontal pipe 101 is 5 times the nominal diameter, which improves the stability of the fluid medium flow velocity.

[0027] Both the horizontal pipe 101 and the vertical pipe 102 are fixedly installed with tongue and groove flanges 6, which can stably connect the horizontal pipe 101 and the vertical pipe 102 and improve the sealing of the connection between the horizontal pipe 101 and the vertical pipe 102.

[0028] The inner and outer surfaces of the elbow body 1 are coated with acrylic resin by electrophoresis. Both the elbow body 1 and the end cap 2 are made of aluminum alloy, which improves the corrosion resistance of the elbow body 1.
