Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a variable diameter heat-insulating ball valve. Background Art

[0002] A variable diameter insulated ball valve is a valve with different inner diameters of connecting flanges at both ends. It is used to connect different pipes and change the net flow rate at the same time. At the same time, an insulating shell is set on the outside to insulate the internal circulating material to prevent it from solidifying inside the valve body.

[0003] The existing solution is generally to install a guide pipe on the insulation shell, and to circulate the external heat medium through the inner wall of the insulation shell to achieve insulation. The operation is cumbersome and requires external heating equipment and medium circulation equipment. The medium in the insulation shell is continuously heated by electric heating. When in use, when the external temperature is high in summer, it is only necessary to heat the internal material when it stops flowing, and no heating and insulation is required during the circulation process. However, the ball valve needs to be kept heated at all times in winter. Therefore, the operator needs to switch the heating element on and off when it is in use and not in use in summer, which is more troublesome. For this purpose, a variable diameter insulation ball valve is specially provided to solve the above problems. Utility Model Content

[0004] In response to the deficiencies of the prior art, the utility model provides a variable diameter insulated ball valve, which solves the problem that when the external temperature is high in summer, heating is only required when the internal material stops flowing, and no heating and insulation is required during the circulation process. However, in winter, the ball valve needs to be kept heated at all times, so the operator needs to switch the heating element on and off when it is in use and not in use in summer, which is quite troublesome.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a variable diameter heat-insulating ball valve, comprising a ball valve body and an electric heat-insulating cover installed on the outside of the ball valve body, a multifunctional regulating switch installed on the top of the ball valve body, and the multifunctional regulating switch comprising a valve handle, a T-shaped clamping column, a sliding clamp and a wedge block;

[0006] The valve handle is fixedly mounted on the ball valve body, the sliding clamp is horizontally slidably arranged inside the valve handle, the wedge block is fixedly arranged at the end of the sliding clamp, the T-shaped clamp column is vertically slidably arranged on the lower surface of the valve handle, and the wedge block is used to push the T-shaped clamp column to move downward;

[0007] A knob-type regulating switch is fixedly installed on the top of the electric heating and heat preservation cover, and the T-shaped clamping column is movably plugged into the knob-type regulating switch.

[0008] Preferably, connecting flanges are installed at both ends of the ball valve body.

[0009] Preferably, the electric heating insulation cover includes an insulation outer cover and an electric heating plate fixedly installed in an inner interlayer of the insulation outer cover, and the knob-type adjustment switch is electrically connected to the electric heating plate.

[0010] Preferably, a water stopper is installed at the bottom of the thermal insulation outer cover, and the water stopper is used to seal the internal interlayer of the thermal insulation outer cover.

[0011] Preferably, a clamping hole is provided on the top of the knob-type regulating switch, and the bottom end of the T-shaped clamping column is movably inserted into the clamping hole.

[0012] Preferably, a fixing tube is fixedly welded to the bottom of the valve handle, the T-shaped clamping column is slidably arranged inside the fixing tube, and a reset spring is movably sleeved on the outer surface of the bottom end of the T-shaped clamping column.

[0013] Preferably, the top end of the T-shaped clamping column extends to the inside of the valve handle, a triangular top block is fixedly provided on the top end of the T-shaped clamping column, and the wedge block is slidably provided on the top of the triangular top block.

[0014] Preferably, a sliding groove is provided inside the valve handle, and the sliding clamp is slidably connected in the sliding groove.

[0016] The utility model discloses a variable diameter heat-insulating ball valve, which has the following beneficial effects: by arranging a multifunctional regulating switch, in summer, the two sets of positioning blocks are pressed toward the middle, and then the sliding clamp is pushed forward, so that the wedge block slides toward the top of the triangular top block, so that the triangular top block drives the T-shaped clamping column to move downward and be inserted into the clamping hole. At this time, during use, when the valve handle is rotated to open and close, the T-shaped clamping column is used to drive the knob-type regulating switch to open and close, so that the electric heater follows the opening and closing of the valve to automatically stop and start. In winter, the sliding clamp is pushed backward, so that the positioning block is stuck in the positioning groove. At this time, the reset spring pushes the T-shaped clamping column upward, and the knob-type regulating switch remains in a normally open state, which is convenient for use in different external temperature environments and avoids the situation where the electric heater is forgotten to start and stop.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides a variable diameter insulated ball valve, which solves the problem that when the external temperature is high in summer, heating is only required when the internal material stops flowing, and no heating and insulation is required during the circulation process. However, in winter, the ball valve needs to be kept heated at all times, so the operator needs to switch the heating element on and off when it is in use and not in use in summer, which is quite troublesome.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The embodiment of the utility model discloses a variable diameter heat-insulating ball valve.

[0027] According to the attached Figure 1-4 As shown, it includes a ball valve body 1 and an electric heating and heat preservation cover 2 installed on the outside of the ball valve body 1. A multifunctional regulating switch 3 is installed on the top of the ball valve body 1. The multifunctional regulating switch 3 includes a valve handle 31, a T-shaped clamping column 33, a sliding clamp 34 and a wedge block 37;

[0028] The valve handle 31 is fixedly mounted on the ball valve body 1 , a sliding clamp 34 is horizontally slidably mounted inside the valve handle 31 , a wedge block 37 is fixedly mounted on the end of the sliding clamp 34 , and a T-shaped clamp 33 is vertically slidably mounted on the lower surface of the valve handle 31 , and the wedge block 37 is used to push the T-shaped clamp 33 downward.

[0029] A knob-type regulating switch 24 is fixedly mounted on the top of the electric heating and heat preservation cover 2 , and the T-shaped clamping column 33 is movably connected to the knob-type regulating switch 24 .

[0030] The top of the knob-type regulating switch 24 is provided with a card hole 25, and the bottom end of the T-shaped card column 33 is movably inserted into the card hole 25. The bottom of the valve handle 31 is fixedly welded with a fixing tube 310, and the T-shaped card column 33 is slidably arranged inside the fixing tube 310. The outer surface of the bottom end of the T-shaped card column 33 is movably sleeved with a return spring 39, and the top of the T-shaped card column 33 extends into the interior of the valve handle 31. The top of the T-shaped card column 33 is fixedly provided with a triangular top block 38, and the wedge block 37 is slidably arranged on the top of the triangular top block 38. A slide groove 32 is provided inside the valve handle 31, and the sliding card 34 is slidably connected to the slide groove 32. Positioning blocks 35 are movably inserted into the two sides of the sliding card 34, and a locking spring 36 is provided between the two groups of positioning blocks 35. A positioning groove 311 is provided on the inner side wall of the slide groove 32, and the positioning block 35 is movably inserted into the interior of the positioning groove 311.

[0031] In summer, the two sets of positioning blocks 35 are pressed toward the middle, and then the sliding clamp 34 is pushed forward, so that the wedge block 37 slides toward the top of the triangular top block 38, so that the triangular top block 38 drives the T-shaped clamping column 33 to move downward and insert into the clamping hole 25. At this time, during use, when the valve handle 31 is rotated to open and close, the T-shaped clamping column 33 is used to drive the knob-type regulating switch 24 to open and close. When the valve is opened, the knob-type regulating switch 24 is closed. At this time, no heating is required to reduce energy consumption. When the valve is closed, the knob-type regulating switch 24 is opened, and the valve body is heated to prevent the conveyed material in a non-flowing state from solidifying inside the valve body, thereby avoiding the situation where energy waste occurs due to forgetting to switch the knob-type regulating switch 24, and forgetting to open it causes the material to condense inside the valve body.

[0032] In winter, the sliding clamp 34 is pushed backward to release the positioning block 35. The locking spring 36 pushes the two sets of positioning blocks 35 outward so that the positioning blocks 35 are stuck in the positioning groove 311 on the rear side. At this time, the return spring 39 pushes the T-shaped clamping column 33 upward. At this time, the knob-type adjustment switch 24 remains in the normally open state, so that the valve body is always heated and kept warm in winter, avoiding the situation where the electric heater 22 is forgotten to be started and stopped.

[0033] Connecting flanges 12 are installed at both ends of the ball valve body 1. The inner diameters of the connecting flanges 12 at both ends are different, so as to change the flow rate.

[0034] The electric heating insulation cover 2 includes an insulation outer cover 21 and an electric heating plate 22 fixedly installed in the inner interlayer of the insulation outer cover 21. The knob-type adjustment switch 24 is electrically connected to the electric heating plate 22, and the knob-type adjustment switch 24 is used to control the start and stop of the electric heating plate 22.

[0035] A water stopper 23 is installed at the bottom of the thermal insulation outer cover 21. The water stopper 23 is used to seal the inner interlayer of the thermal insulation outer cover 21, so as to facilitate the replenishment and replacement of the heat-conducting medium in the inner interlayer of the thermal insulation outer cover 21.
