Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reducing elbows, in particular to an impact-resistant 90-degree reducing elbow. Background Art
[0002] The function of a reducing elbow is to change the diameter of the pipe when making a 90-degree turn. It has the same function as a reducer, but the reducer cannot be used for turning. The price is about twice that of an equal-diameter elbow.
[0003] At some construction sites, a welded elbow and reducer are used instead. Materials include carbon steel, stainless steel, alloy steel, PVC, and cast steel. Reducing elbows are used to connect two pipes of different diameters, allowing for a 90° turn and simultaneously reducing the diameter. The production process involves taper-cutting the entire elbow strip.
[0004] However, most of the reducing elbows on the market still have some shortcomings in some aspects that need further improvement. First, after the reducing elbow has been used for a period of time, the continuous impact of water flow may cause damage or deformation to the inner wall of the bending part of the reducing elbow, reducing its service life. For this reason, an impact-resistant 90-degree reducing elbow is proposed. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide an impact-resistant 90-degree reducer elbow to solve the technical problem mentioned in the above background technology that the inner wall of the bend of the water flow impact equipment is easily damaged and deformed, affecting the service life.
[0006] To achieve the above object, the utility model provides the following technical solutions: an impact-resistant reducing elbow, comprising an elbow body, wherein a slow-flow component is fixedly connected to the inner wall of one end of the elbow body;
[0007] The slow flow assembly includes a support frame rotatably mounted on the inner wall of one side of the elbow body, and the axis of the support frame coincides with the central axis of one end of the elbow body. An impeller is rotatably connected at the center position of the support frame, and the inner wall of the elbow body is located above the impeller and is rotatably connected to a flap. The inner wall of the elbow body is located above the flap and is fixedly connected to a first water blocking block and a second water blocking block.
[0008] By adopting the above technical solution, first the liquid flow drives the impeller to rotate, and at the same time the liquid impacts the flap to rotate, dividing the water flow into two streams and flowing to the first water blocking block and the second water blocking block respectively. When the liquid flows through the first water blocking block and the second water blocking block, the flow direction will be slightly changed, and the liquid impact position will be guided to the middle position inside the elbow body, thereby buffering the faster water flow, reducing the wear of the inner wall of the bending part of the elbow body, and improving the service life.
[0009] Furthermore, a fixing ring is fixedly connected to the outer wall of the impeller, and a water-lubricated bearing is installed at the connection between the impeller and the support frame.
[0010] By adopting the above technical solution, the outer wall of the impeller is fixedly connected with a fixing ring to strengthen its fixation, prevent the blades from being broken by water impact, and improve the stability and life of use.
[0011] Furthermore, the flap is made of stainless steel, and the rotating shaft is rotatably connected via a water-lubricated bearing.
[0012] By adopting the above technical solution, the flap is made of stainless steel, which can prevent rust and increased wear after a period of use, thereby extending the service life.
[0013] Furthermore, the cross-sectional shape of the first water blocking block and the second water blocking block are both triangles with rounded corners, and they are an integrated structure with the inner wall of the elbow body.
[0014] By adopting the above technical solution, the cross-sectional shapes of the first water blocking block and the second water blocking block are both triangles with rounded corners, and the triangular stabilizing mechanism can be used to improve the stability of use. The integrated structure with the inner wall of the elbow body can prevent loosening due to water flow impact.
[0015] Furthermore, the edge of the support frame is fixedly connected to the inner wall of the elbow body through six groups of connecting rods that are symmetrical to each other in the upper and lower directions.
[0016] By adopting the above technical solution, multiple sets of connecting rods can fix the support frame with high strength to ensure the normal operation of the slow flow component.
[0017] Furthermore, one end of the elbow body is fixedly connected to a first butt joint pipe, and the other end of the elbow body is fixedly connected to a second butt joint pipe, and outer walls of the first butt joint pipe and the second butt joint pipe are both provided with thread grooves.
[0018] By adopting the above technical solution, the outer walls of the first butt joint pipe and the second butt joint pipe are both provided with threaded grooves, which can be connected to the pipes at both ends through threaded connection, thereby facilitating quick docking.
[0019] In summary, the present invention has the following beneficial effects:
[0020] The utility model drives the impeller to rotate by the flow of liquid first, and at the same time the liquid impacts the flap to rotate, thereby dividing the water flow into two streams and flowing to the first water blocking block and the second water blocking block respectively. When the liquid flows through the first water blocking block and the second water blocking block, the flow direction will be slightly changed, and the liquid impact position will be guided to the middle position in the elbow body, thereby buffering the faster water flow, reducing the wear of the inner wall of the bending part of the elbow body, and improving the service life.
