Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel thermal insulation valve. Background Art

[0002] During the process of distillation and pipeline material transfer, enterprises usually need to use valves for control. When the valve is closed, materials will remain in the valve. Many materials will crystallize at low temperatures, causing the valve to be unable to be used normally, resulting in a large waste of manpower and time costs. It can only be handled by physical disassembly, electric heating belt heating dredging, spray gun heating dredging, etc. However, the physical disassembly dredging method requires a large waste of manpower and time costs, and the electric heating belt heating dredging method can only be heated to about 60°C, and cannot dredge some materials with higher melting points. Although spray gun heating dredging can effectively dredge various materials, due to the large number of materials in the workshop, open flames cannot be used, and the valve's sealing performance will also decrease after repeated use of the spray gun dredging. Therefore, a new type of thermal insulation valve is needed.

[0003] The existing valve cannot control the temperature of different materials during operation, so a new type of thermal insulation valve is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a new type of thermal insulation valve to solve the problem that the existing valve cannot control the temperature of different materials when in use.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new type of thermal insulation valve, comprising a valve body, a jacket installed on the outer wall of the valve body, a sealing ring installed on the inner wall of the valve body, a float installed on the outer wall of the sealing ring, a valve stem installed on the top of the float, a packing installed on the outer wall of the valve stem, an inner hexagon installed on the outer wall of the valve stem, a handle installed on the outer wall of the inner hexagon, and an insulation interface installed on the outer wall of the valve body.

[0006] Preferably, the inner wall diameter of the jacket is larger than the outer wall diameter of the valve body, and the interior of the jacket is hollow.

[0007] Preferably, the sealing ring is engaged with the float, and the float is threadedly connected to the valve stem.

[0008] Preferably, both sides of the float are of open-hole design, and the float fits tightly against the inner wall of the valve body.

[0009] Preferably, the hexagonal socket is engaged with the handle, and the insulation interface is symmetrically arranged with the central axis of the valve body as the center.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model has a jacket and a thermal insulation interface. When the valve is working, the heat transfer oil is first heated to an appropriate temperature, and the heat transfer oil is introduced from the thermal insulation interface at one end through a pump, enters the jacket outside the valve body, circulates in the jacket, and finally flows back to the thermal oil heater through the thermal insulation interface at the other end. The setting of the thermal insulation interface allows the valve body to be insulated, avoiding blockage caused by cooling and crystallization of residual materials inside the valve body.

[0012] 2. The utility model is equipped with a sealing ring, a float, a valve stem, a packing, an inner hexagon and a handle. When the entire valve body reaches a suitable temperature, the handle can be twisted to drive the inner hexagon, and the inner hexagon drives the valve stem to rotate the float to achieve the purpose of valve opening and closing. For materials that do not require heating, the valve can be closed by twisting the handle and used as an ordinary valve without adding heat transfer oil, thereby reducing the consumption of heat transfer oil and reducing the cost of use.

The two sides of the float 4 are open-hole designed, and the float 4 fits tightly against the inner wall of the valve body 1. Through the provided jacket 2 and insulation interface 9, when the valve is working, the heat transfer oil is first heated to an appropriate temperature, and the heat transfer oil is introduced from the insulation interface 9 at one end through the pump, into the jacket 2 outside the valve body 1, and circulates in the jacket 2, and finally flows back to the heat transfer oil heater through the insulation interface 9 at the other end. The setting of the insulation interface 9 enables the valve body 1 to be insulated, avoiding blockage caused by cooling and crystallization of residual materials inside the valve body 1.
