[0002] In daily life and the production process, the flow of fluids inside pipelines needs to be regulated. These fluids include air, water, etc. The existing regulation methods generally use regulating valves, and the most common ones are ball valves or butterfly valves, etc. In low-pressure pipelines, these are generally manually regulated, while some automatic regulating valves require components such as actuators, which are relatively costly, and the actuators are generally one-to-one corresponding to the regulating valves, that is, a single actuator can only drive a single regulating valve. Summary of the Invention

[0003] In view of the above-mentioned drawbacks of the prior art, the present invention provides a fluid regulating device, which can effectively solve the problems of high regulation cost and inability to simultaneously regulate the flow rates of multiple pipelines by a single actuator in the prior art.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: The present invention provides a fluid regulating device, including pipe fittings, and further including: A flow rate regulating assembly, including an expansion member disposed in a pipe rack. A filling member for filling a medium into an adjustment airbag is provided outside the pipe fitting. When the expansion member expands, it fits against the inner wall of the pipe fitting. When the side wall of the expansion member is squeezed, it further expands on the side close to the pipe fitting.

[0005] Further, the expansion member includes an adjustment airbag, the adjustment airbag is cylindrical, and both ends of the adjustment airbag are provided with frustum reinforcement grooves.

[0006] Further, the expansion member further includes an annular reinforcement airbag installed on the adjustment airbag, and the annular reinforcement airbag and the adjustment airbag are in communication.

[0013] Furthermore, the connection between the connection head and the sealing pipe is a flange connection, a welded connection or a threaded connection.

[0014] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: By providing an expansion member in the pipe fitting and expanding the volume of the expansion member by adding a medium thereto, the flow rate is adjusted by utilizing the volume change. This adjustment method is more suitable for low-pressure pipelines in daily life, and the implementation means has a lower cost. Secondly, a single filling member can complete the adjustment of multiple pipelines. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Embodiment 1: Reference Figure 1 and Figure 2 , a fluid regulating device, including a pipe fitting 1, further including a flow regulating assembly, including an expansion member disposed in a pipe rack 1, an external portion of the pipe fitting 1 is provided with a filling member 10 for filling a medium into an adjusting airbag 5, the filling member 10 is provided with a connecting member 12, a splint group is rotatably mounted on the connecting member 12, the outer wall of the pipe fitting is clamped by the splint group, a sealing pipe 3 is connected to the pipe fitting 1, a connecting head 4 is provided on the adjusting airbag 5, the connecting head 4 is disposed in the sealing pipe 3, the connecting head 4 and the sealing pipe 3 are connected by flange connection, welding connection or threaded connection, a connecting pipe 11 is connected between the connecting head 4 and the filling member 10, the filling member 10 is provided with a plurality of connecting pipes 11, the filling member 10 includes a plurality of filling units, and a single filling unit is connected to a single or a plurality of connecting pipes 11, the filling medium is a liquid or a gas, when the expansion member expands, it fits against the inner wall of the pipe fitting 1, when the side wall of the expansion member is squeezed, it further expands on the side close to the pipe fitting 1, the expansion member includes the adjusting airbag 5, the adjusting airbag 5 is cylindrical, both ends of the adjusting airbag 5 are provided with frustum reinforcement grooves 6, the expansion member further includes an annular reinforcement airbag 7 mounted on the adjusting airbag 5, and the annular reinforcement airbag 7 and the adjusting airbag 5 are communicated with each other, an installation pipe 2 is provided outside the pipe fitting 1, the sealing pipe 3 is located in the installation pipe 2, and a sealing ring is provided between the installation pipe 2 and the sealing pipe 3.

[0021] As Figure 2 shown, in the pipe fitting 1 is the expanded expansion member, and the close contact between the expanded expansion member and the pipe fitting 1 is utilized to achieve the sealing effect, which is a measure taken for the flow of the fluid in the pipe fitting 1. Of course, the medium can also be added to the expansion member according to requirements to complete the expansion, but the side wall of the expansion member will not contact the inner wall of the pipe fitting 1.

[0022] As Figure 3 shown, the specific adjustment process is as follows: when the medium is conveyed into the expansion member, first, the adjusting airbag 5 expands, and then a part of the gas enters the annular reinforcement airbag 7, and both the annular reinforcement airbag 7 and the adjusting airbag 5 expand and the volume becomes larger. According to different volumes, the cross-section of the incoming fluid is blocked to achieve the functions of regulating the flow rate and intercepting the flow.

[0023] Both ends of the adjusting airbag 5 are provided with frustum reinforcement grooves 6. During the interception, the fluid will squeeze the frustum reinforcement groove 6 at one end. As Figure 5 shown, due to the inclined plane of the frustum reinforcement groove 6, on the one hand, the fluid makes the entire adjusting airbag 5 expand towards the inner wall of the pipe fitting 1 by squeezing the inner inclined groove of the frustum reinforcement groove 6, so that the adjusting airbag 5 further squeezes the annular reinforcement airbag 7, making the fit between its outer wall and the inner wall of the pipe fitting 1 better. On the other hand, the adjusting airbag 5 and the annular reinforcement airbag 7 are connected. When the adjusting airbag 5 is squeezed, part of the gas will flow into the annular reinforcement airbag 7, thus improving the sealing (interception) effect.

[0024] Embodiment 2: An annular reinforcement strip 9 is fixedly installed on the adjusting airbag 5. The annular reinforcement strip 9 is provided with an inclined plane on the side close to the annular reinforcement airbag 7, and an annular reinforcement groove 8 is opened on the side of the annular reinforcement airbag 7 close to the annular reinforcement strip 9.

[0025] During the expansion and extrusion deformation of the annular reinforcement airbag 7, the annular reinforcement groove 8 on one side will be squeezed by the annular reinforcement strip 9, further improving the fit between the annular reinforcement airbag 7 and the inner wall of the pipe fitting 1 and further improving the interception effect.

[0026] In addition, the filling part and the expansion part are connected by a connection. Multiple filling units are arranged inside the filling part 10. Here, the filling unit includes a bladder, a cavity or a container. An external driving part (which can be an electric push rod or a motor, etc.) is used to squeeze the internal medium, and the medium enters the expansion part through the connecting pipe 11 to complete the above adjustment or interception.

[0027] The filling unit in the above-mentioned filling part 10 can be connected to a single expansion part or can be connected to multiple expansion parts at the same time. For example, if multiple pipe fittings 1 need to be adjusted synchronously, a single filling unit can be used to connect to multiple expansion parts. Different filling media can be added to different units in the same filling part 10, that is, a single filling part 10 can complete the adjustment of different media in multiple pipe fittings 1 through different media.

[0028] The filling part 10 can be fixed to the pipe fitting 1 by clamping, and of course, the connection method can be changed according to the actual situation.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
