Description

Technical Field

[0001] The utility model relates to the technical field of flow balance valves, and particularly relates to a flow balance valve. Background Art

[0002] A flow balance valve is a valve used to regulate and control the fluid flow. Its main function is to precisely control the flow by changing the flow resistance inside the valve. This kind of valve is widely used in heating, air conditioning, water supply and other systems to ensure the stable operation and high efficiency and energy saving of the system:

[0003] In the prior art, the flow balance valve is usually connected to the pipeline by a flange. However, during the installation of the flow balance valve, the staff needs to support it until one end of the balance valve is connected to the pipeline, which is rather troublesome and affects the installation efficiency of the staff. Content of the Utility Model

[0004] In order to solve the problem that the installation of the flow balance valve is rather troublesome; the purpose of the utility model is to provide a flow balance valve.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a flow balance valve, including a valve body, both ends of the valve body are detachably installed with a first collar and a second collar. The outer sides of the first collar and the second collar are fixedly installed with support plates. A cavity is opened inside the support plate. An activity plate is movably clamped inside the cavity. One end of the activity plate away from the support plate rotatably penetrates through a first threaded rod. One end of the first threaded rod is threadedly sleeved with a sleeve. One end of the sleeve away from the activity plate is fixedly installed with a clamping plate. A uniformly distributed card slot is opened at one end of the activity plate away from the first threaded rod. A clamping plate movably penetrates through the cavity. The clamping plate and the card slot are used in cooperation. The clamping plate and the support plate are fixedly connected by a plurality of springs.

[0006] Preferably, symmetrically distributed L-shaped plates are fixedly installed on one side of the clamping plate close to the activity plate. Symmetrically distributed positioning rods are fixedly installed on one side of the bottom end of the activity plate close to the clamping plate. The two positioning rods respectively penetrate through the corresponding L-shaped plates.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. This application can position the valve body so that it remains in the installed state with the pipeline, avoiding the need for the staff to always support the valve body and improving the efficiency of subsequent installation;

[0009] 2. This application can disassemble the first collar and the second collar, which is convenient for subsequent use of other valve bodies. Description of the Drawings

Specific embodiments

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0016] Embodiment: As Figures 1-3 shown, the present invention provides a flow balance valve, including a valve body 1. Both ends of the valve body 1 are detachably installed with a first collar 11 and a second collar 12. Support plates 13 are fixedly installed on the outer sides of the first collar 11 and the second collar 12. A cavity 14 is opened inside the support plate 13. A movable plate 15 is movably clamped inside the cavity 14. One end of the movable plate 15 away from the support plate 13 rotatably penetrates through a first threaded rod 16. A sleeve 17 is threadedly sleeved at one end of the first threaded rod 16. A clamping plate 18 is fixedly installed at one end of the sleeve 17 away from the movable plate 15. Uniformly distributed card slots 19 are opened at one end of the movable plate 15 away from the first threaded rod 16. A card plate 191 movably penetrates through the cavity 14. The card plate 191 and the card slots 19 are used in cooperation. The card plate 191 and the support plate 13 are fixedly connected by a plurality of springs 192.

[0017] On one side of the clamping plate 18 close to the movable plate 15, symmetrically distributed L-shaped plates 2 are fixedly installed. On one side of the bottom end of the movable plate 15 close to the clamping plate 18, symmetrically distributed positioning rods 21 are fixedly installed, and the two positioning rods 21 respectively penetrate through the corresponding L-shaped plates 2.

[0018] On one side of the support plate 13 close to the spring 192, symmetrically distributed limiting rods 3 are fixedly installed. The limiting rods 3 penetrate through the top of the clamping plate 191. By setting the limiting rods 3, the clamping plate 191 is prevented from shifting during movement, improving its stability.

[0019] A protective pad 4 is fixedly installed inside the clamping plate 18. The protective pad 4 is made of silica gel. By setting the protective pad 4, the surface of the pipeline is prevented from being worn due to excessive force of the clamping plate 18, and the service life of the pipeline is extended.

[0020] Both ends of the first collar 11 are rotatably penetrated by a second threaded rod 5. The second threaded rod 5 is threadedly penetrated through the second collar 12. By rotating the second threaded rod 5, the first collar 11 and the second collar 12 can be disassembled, facilitating the use of other valve bodies 1.

[0021] On both sides of the bottom end of the first collar 11, symmetrically distributed fixing rods 6 are fixedly installed. On both sides of the top end of the second collar 12, symmetrically distributed positioning holes 61 are opened. The fixing rods 6 and the positioning holes 61 are used in cooperation. By setting the fixing rods 6 and the positioning holes 61, the first collar 11 and the second collar 12 can be accurately overlapped, improving stability.

[0022] Limit blocks 7 are fixedly installed at one ends of the plurality of limiting rods 3 away from the support plate 13. By setting the limit blocks 7, the clamping plate 191 is prevented from disengaging from the limiting rods 3.

[0023] The number of the springs 192 and the limiting rods 3 on the outer sides of the plurality of support plates 13 is four each, improving the stability and reset efficiency of the clamping plate 191.

[0024] Working principle: In actual use, the first set of rings 11 and the second set of rings 12 are installed at both ends of the valve body 1. Subsequently, by rotating the first threaded rod 16 on the outer sides of the two movable plates 15, the clamping plates 18 sleeved on the outer sides of the first threaded rod 16 move towards each other until the clamping plates 18 contact the pipeline and apply pressure to it, completing the positioning of the valve body 1; by pulling the clamping plate 191 away from the support plate 13, it is disengaged from the card slot 19. At the same time, when the clamping plate 191 moves, it drives the spring 192 to stretch. At this time, by moving the movable plate 15, the first threaded rod 16 and the clamping plate 18 are driven to move. When in a suitable position, the pulling force on the clamping plate 191 is stopped, so that the spring 192 releases its elastic force to drive the clamping plate 191 to move towards the support plate 13 until the clamping plate 191 is reinserted into the card slot 19 to complete the fixation of the movable plate 15; through the provided L-shaped plate 2 and the positioning rod 21, the clamping plate 18 is prevented from shifting during the movement process, thereby improving the stability of the valve body 1 positioning.

[0025] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
