[0020] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with the specific implementation manner.
[0021] Please refer to Figure 1 and Figure 2 The utility model provides a technical scheme: a continuous thin wall elbow, including wave pipe 1, wave pipe 1's both ends are provided with coaxial link pipe 12, wave pipe 1 is straight pipe structure as a whole, and link pipe 12 is used to connect with the pipeline outside.
[0022] Wave pipe 1 is sleeved with support shaft 2 in the gap, the support shaft 2 is provided with the gate 4 in the trough section 13 of wave pipe 1, the gate 4 controls the size of the flow cross section in the trough section 13, the support shaft 2 and wave pipe 1 are elastically sliding fit and the sliding direction is along the axial direction of link pipe 12, the support shaft 2 can control the flow of fluid flowing in the wave pipe 1 in the positive direction and the reverse direction when moving from the middle to the left and right ends of wave pipe 1 respectively, the both sides of gate 4 are fixedly connected with the resistance increasing plate 41, and the fluid in wave pipe 1 controls the axial movement of support shaft 2 through resistance increasing plate 41, and then drives gate 4 to shift. This kind of setting can stabilize the pressure and flow when discharging fluid.
[0023] Summarizing wave pipe 1 utilizes the bend in it to reduce the pressure of fluid, and can buffer and stabilize the fluid, then utilizes the adaptive movement of gate 4 to stabilize the flow of fluid discharged from wave pipe 1.
[0024] Further, the adjacent trough section 13 on wave pipe 1 is provided with gate 4, the setting can improve the reliability of fluid passing through resistance increasing plate 41 to drive support shaft 2 to move axially, that is to say, when the fluid in wave pipe 1 passes through multiple resistance increasing plates 41, it is difficult to generate enough thrust, and the thrust can drive support shaft 2 to move axially.
[0025] Wherein, positioning sleeve 42 and support shaft 2 are clearance fit and are welded, the setting is convenient for the assembly of gate 4 and support shaft 2, when making, according to the wave distance of wave pipe 1, positioning sleeve 42 on gate 4 is sleeved from one end of support shaft 2, then spot welding is used, and the manufacturing difficulty is reduced.
[0026] The fixed sleeve in the adapter pipe 12 is provided with a positioning ring 5, and a guide frame 51 axially slidingly connected with the support shaft 2 is welded on one side of the positioning ring 5 facing the gate plate 4. In specific implementation, the guide frame 51 is a door-shaped frame structure and is fixedly connected with a guide sleeve sleeved on the outside of the support shaft 2. A reset spring 6 abutting against one end of the support shaft 2 is arranged in the guide frame 51. The reset springs 6 at both ends of the support shaft 2 provide elastic thrust to the axial movement of the support shaft 2. The reset spring 6 plays a role of resetting the support shaft 2. When the flow rate of the fluid in the wave pipe 1 is in an intermediate state, the gate plate 4 is approximately located in the middle of the trough section 13. When the flow rate of the fluid in the wave pipe 1 increases, the support shaft 2 moves axially in one direction. One of the reset springs 6 is compressed. When the flow rate of the fluid in the wave pipe 1 returns to the normal state, the compressed reset spring 6 is stretched and pushes the support shaft 2 to reset.
[0027] Further, the inner peripheral wall of the positioning ring 5 is fixedly connected with a support plate 52. An adjusting screw 7 is screwed through the middle of the support plate 52. In specific implementation, a silk sleeve sleeved on the outside of the adjusting screw 7 can be fixedly arranged in the middle of the support plate 52. One end of the adjusting screw 7 abuts against the other end of the reset spring 6. When the adjusting screw 7 rotates, the pressure of the reset spring 6 can be adjusted. Thus, the flow rate of the fluid discharged by the thin-wall elbow can be adjusted. A limiting shaft sleeved in the reset spring 6 can be welded on one end of the adjusting screw 7. A guide hole slidingly fitted with the limiting shaft is formed in one end of the support shaft 2.
[0028] In the embodiment, the wave angle of the wave pipe 1 is 90 degrees. A plurality of 90-degree elbows can be connected in series by welding to be made, or can be integrally formed by casting. The thin-wall structure is used to reduce the manufacturing difficulty.
[0029] Working principle: The thin-wall elbow is taken as an example to control the flow rate by connecting a spray head. When in use, the external water supply pipe is connected with the thin-wall elbow and the external spray head. When the water pressure in the water supply pipe is too large to cause the flow rate to increase, the water body is first reduced in pressure by the wave pipe 1, and then the flow rate is reduced. When the water body flows, the resistance plate 41 is pushed. At this time, the support shaft 2 moves axially, the reset spring 6 is compressed, the gate plate 4 moves and reduces the flow cross section in the trough section 13, thereby reducing the flow rate of the water body discharged from the wave pipe 1, so that the water body supplied to the spray head is in a state of approximately steady flow. Not only the spray head can be protected, but also the water mist sprayed by the spray head can be in a stable state.
[0030] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature described. The specification can include implicit combinations of explicitly mentioned features and / or explicit combinations of implicitely mentioned features. Each embodiment depends on the explicit combinations of features and / or the implicit combinations of features made specifically within that embodiment, and each such embodiment can be combined with every other such embodiment to create further embodiments.
