Abstract
The utility model provides a valve heat-preserving sleeve, which comprises an outer shell and heat-preserving layers, wherein the outer shell is formed by combining two shells; the heat-preserving layers are adhered to the inner walls of the outer shell; the two shells are respectively provided with a valve body inlet, a valve body outlet and a valve rod accommodation opening; flange edges are arranged at the edges of the two shells; a plurality of bolt holes are formed in each flange edge at intervals; the two shells are fixedly connected through bolts; and the two shells to which the heat-preserving layers are adhered are combined to form a space for accommodating a valve body and a valve rod. The valve heat-preserving sleeve can meet requirements of valve heat-preserving systems for equipment and pipelines of different types and specifications, in different using environments and at different medium temperatures, and can be widely applied to heat insulation and heat preservation of various valves on cold and hot equipment and the pipelines, particularly to valves of the equipment and the pipelines, which are required to be frequently disassembled, maintained and cleaned.
Description
Technical field
The utility model relates to a kind of valve lagging, can be widely used in the valve insulation on heating power, chiller plant and the various valve body in fields such as petrochemical industry, textile printing and dyeing, electric power metallurgy, papermaking printing, bio-pharmaceuticals, food and drink, boats and ships locomotive, HVAC.
Background technique
Along with the fast development of petrochemical industry, electric power, oil, chemical industry, the energy-conservation common concern that more and more receives people.Insulation how to carry out equipment appurtenance becomes the important topic of pendulum in face of people.Valve is important heating position in the thermodynamic system, also is the weak part that needs special concern in the pipeline.According to adjusting, the heat of one DN50-300 ℃ the annual loss of exposed valve be equivalent to the to burn heating value of one ton of fuel oil.The valve of petrochemical equipment is ten hundreds of, and the quality of its insulation directly affects the energy consumption and the economic benefit of device.
The structure of existing valve lagging is roughly the same, mainly is made up of thermal-protective coating and insulation shell, and thermal-protective coating wherein generally is directly to be wrapped on the valve, and insulation shell is enclosed within on the thermal-protective coating outer surface.The defective of its existence is: installation and removal are inconvenient; Thermal-protective coating can not former state be reused, and cost is higher.
The model utility content
The purpose of the utility model is to provide a kind of valve lagging, with the requirement of the valve heat-insulation system that satisfies different Environmental Conditions, different medium temperature, different model specification equipment and pipeline; Be widely used in the various valve adiabatic heat-insulations on cold and hot equipment and the pipeline.This valve lagging is often dismantled for needs, maintenance, and the equipment of cleaning and the valve of pipeline are particularly suitable.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of valve lagging comprises shell and thermal insulation layer, this shell by about two shell combination form; Thermal insulation layer is bonded in outer casing inner wall, and two housings have the valve body of confession respectively to be imported and exported and the ccontaining opening of valve rod, and the edge of two housings is provided with flange edge; Be interval with some bolts hole on the flange edge; Two housings connect through bolt, be bonded with two shell combination of thermal insulation layer after, just form and supply valve body and the ccontaining space of valve rod.
Said outer casing inner wall is provided with netted fin.
Said flange edge is located at housing along on the edge of valve body direction and corresponding on the edge between valve body and the valve rod.
The thickness of said housing is 3-6mm.
The thickness of said thermal insulation layer is 5-50mm.
The advantage of the utility model is:
1, the valve lagging of the utility model is simple in structure, is easy to install, and is for convenience detach, is convenient to maintenance.
2, the valve lagging intensity of the utility model is high, can effectively protect valve safety, reduces and reduces valve corrosion and anti-condensation, prolongs valve working life; Can reuse long service life.
3, the valve lagging appearance looks elegant of the utility model is clean and tidy, surperficial scrubbing resistance; Environmental protection, pollution-free, harmless fully to human and environment.
