Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve sphere that prevents freezing. Background Art

[0002] A ball valve is a valve in which the opening and closing member (sphere) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels.

[0003] Since the opening and closing of the ball valve are realized through the rotational connection of the sphere, when the ball valve is closed, water accumulates in the passage of the sphere. Once encountering cold weather, the residual water in the sphere is very easy to freeze, affecting the use of the ball valve. Moreover, when the water freezes, its volume expands, thereby squeezing the sphere, and it is extremely easy to cause damage to the sphere. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose a ball valve sphere that prevents freezing.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: Design a ball valve sphere that prevents freezing, including a valve body. The two ends of the valve body are respectively connected with a first through pipe and a second through pipe. The first through pipe and the second through pipe correspond to each other. A sphere is arranged in the middle of the valve body. A water through hole corresponding to the first through pipe is opened in the middle of the sphere. A valve stem is connected to the top of the sphere, and a support shaft is connected to the bottom of the sphere. The support shaft is rotatably installed on a support seat, and the support seat is installed on the bottom of the valve body;

[0006] A first annular plate is installed at the bottom of the support seat, and a number of slots arranged at intervals are opened along the edge of the support seat;

[0007] The utility model further includes a chassis, which is arranged below the valve body. A controller, a battery pack, and a heating plate are arranged inside the chassis. The controller is connected to the battery pack and the heating plate respectively through wires. The heating plate is installed on a support plate, and the support plate is fixedly connected to the inside of the chassis;

[0008] A second annular plate is rotatably installed on the top of the chassis. The second annular plate is sleeved on the first annular plate and the two are threadedly connected. A number of flexible heat conduction sheets are arranged inside the second annular plate. The heat conduction sheets correspond to the slots. The heat conduction sheets penetrate through the chassis and are connected to the heating plate, and the heat conduction sheets are fixedly connected to the chassis.

[0009] Preferably, valve seats are installed at both inner ends of the valve body, and the valve seats are in clearance fit with the outer wall of the sphere.

[0010] Preferably, a shrapnel is correspondingly installed inside each heat conducting sheet, and the shrapnel is arranged along the length direction of the heat conducting sheet.

[0011] Preferably, a gasket is provided inside the second annular plate. The gasket corresponds to the support seat and is fixed on the top of the chassis.

[0012] Preferably, a temperature sensor is installed on one side of the chassis, and the temperature sensor is connected to the controller through a wire.

[0017] 2. For the anti-freezing ball valve, the sphere is threadedly connected to the first annular plate through the second annular plate, which facilitates the removal of the chassis from the valve body for maintenance operations on the heat conducting sheet, heating plate, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1 - 5 , an anti-freezing ball valve sphere, including a valve body 1, the two ends of the valve body 1 are respectively connected with a first through pipe 3 and a second through pipe 4, the first through pipe 3 and the second through pipe 4 correspond to each other, a sphere 2 is arranged in the middle of the valve body 1, a water through hole 5 corresponding to the first through pipe 3 is opened in the middle of the sphere 2, and a valve stem 6 is connected to the top of the sphere 2, a support shaft 8 is connected to the bottom of the sphere 2, the support shaft 8 is rotatably installed on a support base 9, the support base 9 is installed on the bottom of the valve body 1, valve seats 7 are installed at both ends inside the valve body 1, the valve seats 7 are in clearance fit with the outer wall of the sphere 2, so that when the sphere 2 rotates, the tightness between the sphere 2 and the valve body 1 is ensured, and water is prevented from flowing through the gap between the sphere 2 and the valve body 1, thereby affecting the normal use of the ball valve.

[0026] As Figure 3 shown, a first annular plate 10 is installed at the bottom of the support base 9, and a plurality of slots 11 arranged at intervals are opened along the edge of the support base 9; the present invention further includes a chassis 12, the chassis 12 is arranged below the valve body 1, a second annular plate 16 is rotatably installed on the top of the chassis 12, the second annular plate 16 is sleeved on the first annular plate 10 and the two are threadedly connected, a plurality of flexible heat conducting sheets 15 are arranged inside the second annular plate 16, the heat conducting sheets 15 correspond to the slots 11, the heat conducting sheets 15 penetrate through the chassis 12 and are connected to the heating plate 14, and the heat conducting sheets 15 are fixedly connected with the chassis 12.

[0027] After the ball valve is installed, place the chassis 12 below the valve body 1. First, align the heat-conducting sheet 15 with the slot 11, and then connect it to the first annular plate 10 by screwing the second annular plate 16, thereby fixing the chassis 12 on the valve body 1. At this time, the heat-conducting sheet 15 will extend into the valve body 1 and contact the bottom surface of the sphere 2. Since an elastic sheet 17 is correspondingly installed inside each heat-conducting sheet 15, and the elastic sheet 17 is arranged along the length direction of the heat-conducting sheet 15, the heat-conducting sheet 15 can closely adhere to the sphere 2 under the elastic action of the elastic sheet 17. As Figure 5 shown, a controller 22, a battery pack 20 and a heating plate 14 are arranged inside the chassis 12. The controller 22 is connected to the battery pack 20 and the heating plate 14 respectively through wires. The heating plate 14 is installed on the support plate 13, and the support plate 13 is fixedly connected to the inside of the chassis 12. The heating plate 14 generates heat and transfers it to the sphere 2 through the heat-conducting sheet 15, thereby heating the sphere 2 and reducing the probability of the water in the water through-hole 5 freezing.

[0028] In order to improve the sealing performance between the chassis 12 and the valve body 1 after the chassis 12 is installed, as Figure 4 shown, a sealing gasket 19 is provided inside the second annular plate 16. The sealing gasket 19 corresponds to the support seat 9, and the sealing gasket 19 is fixed on the top of the chassis 12.

[0029] Specifically, in the actual use process, the controller 22 is one of a control main board and a PLC logic controller. A temperature sensor 21 is installed on one side of the chassis 12. The temperature sensor 21 is connected to the controller 22 through a wire, can monitor the temperature in the environment where the ball valve is located, and feedback to the controller 22, thereby realizing real-time control of the operation of the heating plate 14.

[0030] If the heat transferred by the heat-conducting sheet 15 to the sphere 2 is insufficient during the use process, as Figure 3 shown, an annular groove 25 is coaxially opened inside the water through-hole 5, and an annular buffer rubber film 24 is arranged in the water through-hole 5. The side surface of the buffer rubber film 24 is correspondingly connected to the side surface of the annular groove 25. At this time, the expansion generated after the water freezes will act on the buffer rubber film 24, causing it to deform towards the annular groove 25, thereby further improving the anti-freezing ability of the sphere 2 and avoiding the ball valve from being unable to be used normally due to situations such as insufficient power supply of the heating plate 14 or damage to the heating plate.

[0031] Furthermore, in order to facilitate operations such as replacing the battery pack 20, an opening 23 is provided on one side of the chassis 12. One side of the opening 23 is hinged with a sealing door 18, and the other side of the sealing door 18 is connected to the chassis 12 through a lock.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
