Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, the present invention provides an energy-saving integrated thermal insulation body for power plant valves, which includes a first FRP shell 1 and a second FRP shell 3 oppositely arranged. The first FRP shell 1 is provided with a first thermal insulation lining 2, and the second The FRP shell 3 is provided with a second thermal insulation lining 4. When the first thermal insulation lining 2 is combined with the second thermal insulation lining 4, a thermal insulation chamber 5 matching the shape of the valve is formed. The first thermal insulation lining 2 and the second thermal insulation The lining layer 4 is an insulating lining layer made of ceramic composite heat insulating material. The first FRP shell 1 and the second FRP shell 3 are provided with joints. The performance of the ceramic composite heat insulating material is stable after curing, and the heat insulation effect is good. The service life is long, and compared w...

Embodiment 2

[0034] Such as image 3 As shown, the present invention provides an energy-saving integrated thermal insulation body for power plant valves. Its structure is basically the same as that of Embodiment 1. The second buckle flange 302 that is arranged on the periphery of the second FRP shell 3, the inner diameter of the first buckle flange 102 is adapted to the outer diameter of the second buckle flange 302, and the second buckle flange 302 can be directly The buckle is in the first buckle flange 102 to achieve an interference fit, so that the first FRP shell 1 and the second FRP shell 3 achieve the effect of being fastened together.

[0035] The structure of the joint part does not need to use fasteners, which is more convenient for disassembly and maintenance, and further improves the performance of the present invention.

Embodiment 3

[0037] Such as Figure 4As shown, the present invention provides an energy-saving integrated thermal insulation body for power plant valves. Its structure is basically the same as that of Embodiment 1. On the second mounting flange 303 on the periphery of the second FRP shell 3, the first mounting flange 103 is provided with an annular notch 1031 suitable for the second mounting flange 303. During use, the second mounting flange 303 buckles fit in the annular notch 1031 to realize the fastening connection between the first FRP shell 1 and the second FRP shell 3, of course, in order to improve the joint fastening degree between the first FRP shell 1 and the second FRP shell 3, it can be Apply adhesive glue in the annular seam 1031 to make the combination of the two more firm, and can be slightly heated during disassembly to separate the two.

Abstract

The invention discloses an energy-saving integrated heat preservation body of a power plant valve and a manufacturing method of the energy-saving integrated heat preservation body of the power plant valve and belongs to the technical field of heat preservation of valves. The energy-saving integrated heat preservation body of the power plant valve comprises a first fiber reinforced plastic shell and a second fiber reinforced plastic shell which are arranged oppositely. A first heat preservation lining is arranged inside the first fiber reinforced plastic shell. A second heat preservation lining is arranged inside the second fiber reinforced plastic shell. When the first heat preservation lining and the second heat preservation lining are combined, a heat preservation cavity which is matched with the valve in shape is formed. The first heat preservation lining and the second heat preservation lining are both heat preservation linings made of a ceramic composite heat insulation material. Combining portions are arranged on the peripheries of the first fiber reinforced plastic shell and the second fiber reinforced plastic shell. The energy-saving integrated heat preservation body of the power plant valve and the manufacturing method of the energy-saving integrated heat preservation body of the power plant valve solve the technical problems that an existing heat preservation body of the valve is difficult to assemble and disassemble and inconvenient to maintain and heat preservation fiber contained in the existing heat preservation body of the valve does great harm to human bodies and are widely applied to heat preservation of the power plant valves.

Description

technical field [0001] The invention relates to the technical field of valve heat preservation, in particular to an energy-saving integrated heat preservation body for valves in power plants. Background technique [0002] The valve is an important hub in the thermal system, and it will lose a lot of heat when transporting hot fluid. In industrial production, all kinds of pipelines and equipment need to be insulated. Some traditional materials and technologies cannot be used for special parts of pipelines or valves. Insulation, so a lot of heat is lost from the valve, and serious oxidation and corrosion will occur over time, but the valve is often a weak part in the pipeline and needs special attention. When disassembling the valve, it is often installed on the valve. Insulation materials have become a difficult point in the maintenance of valves, such as having to re-insulate, or when disassembling or installing insulation materials, they will come into contact with glass fi...
