Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a manual flat valve with a valve plate having a heating effect. Background Technology

[0002] Currently, when using pipelines outdoors or in low-temperature environments, insulation measures such as wrapping the outside of the pipeline are usually taken. However, due to the large size and irregular shape of valves, it is generally difficult to take insulation measures for valves. As a result, the water source in the pipeline near the valve area is prone to freezing at low temperatures, making it difficult to pass water even after the valve is opened.

[0003] In existing low-temperature environments, water in the pipes near the valve body is prone to freezing, which makes it difficult for water to flow normally between the two sections of pipes connected by the flat plate valve after the valve is opened. Therefore, a manual flat plate valve with a heating effect is proposed. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides a manual flat valve with a heating function on the valve plate. This provides a set of manual flat valves with heating function for pipeline systems, suitable for use in outdoor or low-temperature environments. When it is difficult to perform heat preservation treatment due to the limitations of the valve body structure at low temperatures, the valve plate with electric heating tape can heat the frozen water source in the two sections of the pipeline located on the flat valve, causing the ice to melt. This allows the two sections of the pipeline to flow normally after the flat valve is opened, ensuring the reliability of the pipeline water supply.

[0005] The technical solution adopted by this utility model to solve its technical problem is a manual flat valve with a valve plate having a heating effect, including a support frame, a valve sleeve, and a valve plate part. The valve sleeve is fixedly connected to the bottom of the support frame, and the valve plate part is disposed inside the valve sleeve.

[0006] The valve plate includes a first valve plate and a second valve plate. A wire tracing groove is provided on an adjacent side of the first valve plate and the second valve plate. An electric heating tape is installed in the wire tracing groove. The first valve plate and the second valve plate are welded together on their outer peripheries.

[0007] By adopting the above technical solution, a set of manual flat valves with heating effect is provided for the pipeline system through the components composed of support frame, valve sleeve and valve plate. It is suitable for use in pipelines outdoors or in low-temperature environments. When it is difficult to perform heat preservation treatment due to the limitations of the valve body structure at low temperatures, the valve plate with electric heating tape can be used to heat the frozen water source in the two sections of the pipeline located in the flat valve, so that the ice melts and the two sections of the pipeline can flow normally after the flat valve is opened, thus ensuring the reliability of the pipeline water supply.

[0008] Specifically, the top of the second valve plate is provided with an internal threaded sleeve, and the internal threaded sleeve is internally threaded to a screw rod. The top of the screw rod is rotatably connected to the top of the support frame through a bearing seat, and the top of the screw rod extends through the top of the support frame and is equipped with a first bevel tooth.

[0009] Specifically, the support frame has linear guide rails on both sides for connecting the wires on both sides of the valve plate. A shaft is rotatably mounted on one side of the top of the support frame via a bearing seat. One end of the shaft is connected to a second bevel tooth, which meshes with the first bevel tooth. A handwheel is connected to the end of the shaft away from the second bevel tooth.

[0010] By adopting the above technical solution, through the setting of the first bevel gear and the second bevel gear, after the operator rotates the handwheel of the shaft, the second bevel gear will be driven to rotate, thereby causing the first bevel gear to drive the screw to rotate. Furthermore, based on the threaded connection between the internal threaded sleeve and the screw, the internal threaded sleeve can drive the valve plate to move up and down in the valve sleeve, thereby realizing the opening and closing of the valve sleeve.

[0011] Specifically, the valve sleeve has an opening at the top for inserting the valve plate. The inner circumference of the opening is provided with a rubber sealing strip with an inflation cavity. A piston sleeve is connected to one side of the valve sleeve. One end of the piston sleeve is connected to the rubber sealing strip through an air pipe, and the piston sleeve communicates with the inflation cavity of the rubber sealing strip.

[0012] Specifically, a threaded rod is threaded into the other end of the piston sleeve, one end of the threaded rod is connected to a piston head, the piston head is located inside the piston sleeve, and a knob is provided at the end of the threaded rod away from the piston head.

[0013] By adopting the above technical solution, and through the setting of the rubber sealing strip, after the operator has opened and closed the valve plate, the knob can be rotated to make the threaded rod drive the piston head to move inside the piston sleeve, thereby expelling the air inside the piston sleeve into the rubber sealing strip, causing the rubber sealing strip to expand, thereby improving the sealing performance between the valve sleeve and the valve plate.

[0014] Specifically, a battery for supplying power to the electric heating cable is installed on one side of the support frame, and a temperature control switch is installed on the other side of the battery.

[0015] The beneficial effects of this utility model are as follows: The assembly consisting of a support frame, valve sleeve, and valve plate provides a set of manual flat valves with heating capabilities for pipeline systems. It is suitable for outdoor or low-temperature environments. In situations where insulation is difficult due to the limitations of the valve body's structure at low temperatures, the valve plate, equipped with an electric heating tape, can heat the frozen water in the two sections of the flat valve, melting the ice. This allows for normal water flow in both sections after the flat valve is opened, ensuring reliable water flow. This solves the problem that in existing low-temperature environments, water in the pipes near the valve body easily freezes, hindering normal water flow between the two sections of the pipe connected by the flat valve after opening.

[0025] like Figure 1-6As shown, the present invention provides a manual flat valve with a valve plate having a heating effect, comprising a support frame 1, a valve sleeve 2, and a valve plate 3. The valve sleeve 2 is fixedly connected to the bottom of the support frame 1, and the valve plate 3 is disposed inside the valve sleeve 2.

[0026] The valve plate portion 3 includes a first valve plate 31 and a second valve plate 32. A wire groove 33 is provided on an adjacent side of the first valve plate 31 and the second valve plate 32. An electric heating tape 34 is provided in the wire groove 33. The first valve plate 31 and the second valve plate 32 are welded together on their outer periphery.

[0027] When in use, the support frame 1, valve sleeve 2, and valve plate 3 provide a set of manual flat valves with heating effect for the pipeline system. It is suitable for use in outdoor or low-temperature environments. When it is difficult to perform heat preservation treatment due to the limitations of the valve body structure at low temperatures, the valve plate 3 equipped with electric heating tape 34 can be used to heat the frozen water source in the two sections of the flat valve pipeline.

[0028] The present invention also includes that the top of the second valve plate 32 is provided with an internal threaded sleeve 35, and the internal threaded sleeve 35 is internally threaded to a screw 36. The top of the screw 36 is rotatably connected to the top of the support frame 1 through a bearing seat, and the top of the screw 36 extends through the top of the support frame 1 and is equipped with a first bevel tooth 37.

[0029] The present invention also includes linear guide rails 11 for connecting the wires on both sides of the valve plate 3 inside the support frame 1. A shaft 12 is rotatably mounted on one side of the top of the support frame 1 via a bearing seat. One end of the shaft 12 is connected to a second bevel tooth 13, and the second bevel tooth 13 meshes with a first bevel tooth 37. A handwheel 14 is connected to the end of the shaft 12 away from the second bevel tooth 13.

[0030] In use, based on the setting of the first bevel tooth 37 and the second bevel tooth 13, after the operator rotates the handwheel 14 of the shaft 12, the second bevel tooth 13 will be driven to rotate, which in turn causes the first bevel tooth 37 to drive the screw 36 to rotate. Furthermore, based on the threaded connection between the inner threaded sleeve 35 and the screw 36, the inner threaded sleeve 35 can drive the valve plate part 3 to move up and down in the valve sleeve 2, thereby realizing the opening and closing of the valve sleeve 2.

[0031] The present invention also includes a socket 21 for inserting the valve plate 3 at the top of the valve sleeve 2, a rubber sealing strip 22 with an inflation cavity provided on the inner circumference of the socket 21, a piston sleeve 23 connected to one side of the valve sleeve 2, one end of the piston sleeve 23 being connected to the rubber sealing strip 22 through an air pipe, and the piston sleeve 23 communicating with the inflation cavity of the rubber sealing strip 22.

[0032] The present invention also includes a threaded rod 24 threadedly inserted at the other end of the piston sleeve 23, a piston head 25 connected to one end of the threaded rod 24, the piston head 25 being located inside the piston sleeve 23, and a knob 26 being provided at the end of the threaded rod 24 away from the piston head 25.

[0033] In use, by utilizing the rubber sealing strip 22, after the operator has opened and closed the valve plate 3, the knob 26 can be rotated to cause the threaded rod 24 to drive the piston head 25 to move inside the piston sleeve 23, thereby expelling the air inside the piston sleeve 23 into the rubber sealing strip 22, causing the rubber sealing strip 22 to expand, thereby improving the sealing performance between the valve sleeve 2 and the valve plate 3.

[0034] The present invention also includes a battery 5 for supplying power to the electric heating cable 34 installed on one side of the support frame 1, and a temperature control switch 6 installed on one side of the battery 5.

[0035] In use, the output terminal of the storage battery 5 is electrically connected to the input terminal of the electric heating tape 34 through a wire, and the output terminal of the temperature control switch 6 is electrically connected to the output terminal of the electric heating tape 34 through a wire.

[0036] In use, the two ends of the valve sleeve 2 are connected to the pipes to be connected in series. When the valve needs to be opened or closed, the operator rotates the handwheel 14 of the shaft 12 to drive the second bevel gear 13 to rotate, which in turn causes the first bevel gear 37 to drive the screw 36 to rotate. Based on the threaded connection between the inner threaded sleeve 35 and the screw 36, the inner threaded sleeve 35 can drive the valve plate 3 to move up and down in the valve sleeve 2, thereby opening and closing the valve sleeve 2. In the event of low temperatures and ice forming in the pipes near the valve, the operator can turn on the temperature control switch 6 to activate the electric heating tape 34. The electric heating tape 34 heats the first valve plate 31 and the second valve plate 32, melting the ice near the valve and facilitating water flow in the pipeline. During this process, the operator should periodically check the pipes.

[0037] After the operator opens or closes the valve plate 3, the knob 26 can be rotated to cause the threaded rod 24 to drive the piston head 25 to move inside the piston sleeve 23, thereby expelling the air inside the piston sleeve 23 into the rubber sealing strip 22, causing the rubber sealing strip 22 to expand, thus improving the sealing performance between the valve sleeve 2 and the valve plate 3.

[0038] Among them, the storage battery 5 is charged by the staff regularly, or the storage battery 5 is not used, and the power supply line around the site is used to provide power to the electric heating tape 34.
