Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a self-sealing pressure-controlling valve. Background Art

[0002] A valve is a device used to control the flow of fluids, with functions such as opening, closing and regulating fluid flow. Valves can be divided into many types according to their working principles and structures, such as ball valves, butterfly valves, gate valves, stop valves, etc. Valve self-sealing pressure control means that when the valve is in the closed state, it realizes automatic control of the fluid through the internal structure design, so as to achieve the purpose of regulating parameters such as pressure and flow. However, some of the current valves are usually heavy and bulky, and are relatively difficult to operate. As a result, when the flange on the valve is fully aligned with the flange on the pipeline, it requires the cooperation of multiple people to ensure the accuracy of the alignment, but the cooperation of multiple people will lead to different opinions, methods and working habits, and when multiple people need to communicate, there will be difficulties or misunderstandings, which will lead to slow progress of work.

DETAILED DESCRIPTION

[0019] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] It should be noted that the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1-Figure 5As shown, a self-sealing pressure-control valve proposed by the utility model includes a valve body 1 and a pair of flange connecting pipes 2 arranged at the bottom of the valve body 1, and the ends of the flange connecting pipes 2 away from the valve body 1 are provided with flanges for connecting to pipelines, and also include: a supporting mechanism fixedly sleeved on the flange connecting pipes 2 for allowing the valve body 1 to move only up and down; and a binding mechanism arranged on the supporting mechanism for fixing the flange connecting pipes 2 on the pipeline.

[0026] Furthermore, the supporting mechanism includes an annular sleeve block 3 fixedly mounted on the flange connecting pipe 2, a pair of rotating seats 31 being fixedly connected to the annular sleeve block 3, the rotating seat 31 being rotatably connected to a first limiting rotating rod 32, the first limiting rotating rod 32 being rotatably connected to a second limiting rotating rod 33 at one end away from the rotating seat 31, the second limiting rotating rod 33 being rotatably connected to a third limiting rotating rod 34 at one end away from the first limiting rotating rod 32, each of the first limiting rotating rod 32, the second limiting rotating rod 33 and the third limiting rotating rod 34 are in a pair, and their function is to increase the strength of the first limiting rotating rod 32, the second limiting rotating rod 33 and the third limiting rotating rod 34. The third limit rotating rod 34 is rotatably connected to the rotating block 4 at one end away from the second limit rotating rod 33. The first limit rotating rod 32, the second limit rotating rod 33, the third limit rotating rod 34 and the rotating block 4 are rotatably connected via a rotating shaft 35. The rotating shafts 35 on the connected ends of the rotating block 4, the first limit rotating rod 32, the second limit rotating rod 33 and the third limit rotating rod 34 are movably sleeved with a limit sleeve rod 36. The function of the limit sleeve rod 36 is to prevent the first limit rotating rod 32, the second limit rotating rod 33 and the third limit rotating rod 34 from sliding on the rotating shaft 35, so as to avoid the spacing between each pair of the first limit rotating rod 32, the second limit rotating rod 33 and the third limit rotating rod 34 from changing arbitrarily.

[0027] Furthermore, the binding mechanism includes a first arc-shaped jacket 41 and a second arc-shaped jacket 43 rotatably connected to the rotating block 4, and a binding band 44 is rotatably connected to the second arc-shaped jacket 43. One end of the binding band 44 is provided with a mounting screw 45, and the mounting screw 45 is used to be inserted into the corresponding first arc-shaped jacket 41 according to the thickness of the pipeline. The first arc-shaped jacket 41 is provided with a mounting fixing hole 42 spirally connected to the mounting screw 45, and the first arc-shaped jacket 41, the second arc-shaped jacket 43 and the binding band 44 are all provided with linearly arranged grooves 46. The function of the grooves 46 is to increase the friction between the first arc-shaped jacket 41, the second arc-shaped jacket 43 and the binding band 44 and the pipeline, so that the first arc-shaped jacket 41, the second arc-shaped jacket 43 and the binding band 44 are more firmly fixed on the pipeline, which helps to prevent the first arc-shaped jacket 41, the second arc-shaped jacket 43 and the binding band 44 from sliding or loosening on the pipeline.

[0028] In this embodiment, when a self-sealing pressure control valve is required, Figure 1As shown, the valve body 1 is first transported to the bottom of a pair of pipe connection ends by a handling device, so that the valve body 1 is lifted to the height to be installed with the pipes, and the valve body 1 is located in the middle of the pair of pipe connection ends. Then the strap mechanism on the rotating block 4 is installed on the corresponding upper pipe, as shown in FIG. Figure 5 As shown, at this time, the first arc-shaped jacket 41 and the second arc-shaped jacket 43 need to clamp the pipeline, and then the groove 46 needs to wrap around the pipeline, and then the mounting screw 45 on the end of the groove 46 needs to be inserted into the mounting fixing hole 42 on the first arc-shaped jacket 41, and at the same time, the first arc-shaped jacket 41 and the second arc-shaped jacket 43 need to tightly clamp the pipeline. Then, the valve body 1 is lifted up and down using a heavy lifting device, and at this time, the valve body 1 is restricted by the support mechanism, so that the direction of the valve body 1 can be prevented from shaking. Finally, the flange connection pipe 2 at the bottom of the valve body 1 is lifted to a specified height, and the flange connection pipe 2 at the bottom of the valve body 1 can be installed with the pipeline. Therefore, it only needs to make the heavy lifting device and the binding mechanism cooperate, and it does not require multiple people to operate, which is convenient and quick.
