Abstract
The utility model relates to a valve protecting cover, belonging to the techncial field of liquid pipeline adjunctive articles. The utility model consists of two mutual looping symmetrical cavities. The two symmetrical cavities are provided with arc openings and have the petals of a ying and yang fabric. The ying petal axis hems a valgus L-shaped towards the edge; the yang petal axis hems a valgus level towards the edge. The vertical distance between the two hems of the yang petal equals to that between the vertical inner edges of the two hens of the ying petal. The axes direction edge of the two cavity axes are provided with level hems. The corresponding places of the two cavity hems are provided with interconnecting pieces. The axes direction edge of the two cavity axes are provided with level hems; one side of the two cavities is hemed and articulated; the other edge is provided with interconnecting pieces. The walls of the two cavities are covered by heat insulator layers. The utility model is easy to install and maintain.
Description
Technical field
The utility model belongs to fluid line appurtenance technical field, the particularly a kind of insulation of fluid line valve, corrosion-resistant safety cover of being used for.
Background technique
At petrochemical industry, coal separation, coal washing industry, the thermal insulating material of various valves all is glass wool, alumina silicate, rock wool and so on.When being incubated installation, at first need valve surface is arrived in these material pavings, also fixed at the outside of thermal insulating material covering one deck aluminium foil or iron sheet then.This heat insulation protecting way construction is complicated, the repair and replacement trouble.Though can play the certain protection effect to valve, elbow, anticorrosion, flame retardant property is poor, iron sheet, the aluminium foil that is covered in the thermal insulating material outside is subject to corrosion such as atmosphere, rainwater and damages, and needs often replacing, not only polluted easily but also influences production.
The model utility content
The utility model purpose is to provide a kind of installation, maintenance simple valve protective cap.
For reaching above-mentioned purpose, the utility model adopts following technological scheme: valve protective cap, constitute by half chamber of two symmetries of mutual fastening, and the two halves cavity edge is provided with the arc gap.
Two and half chambeies are yin, yang two valve structures, and cloudy lobe axial edge has the L shaped flanging that turns up, and positive lobe axial edge has the horizontal flanging that turns up, and perpendicular distance equals perpendicular distance between the cloudy lobe two flanging vertical edge inner edges between positive lobe two hemmed edges.
Two and half chamber axial edge are provided with horizontal flanging, and corresponding position is provided with link on the flanging of two halves chamber.
Two and half chamber axial edge are provided with horizontal flanging, and two halves chamber one side edgefold is hinged, and the opposite side edge is provided with fixed block.
The two halves cavity wall is covered with adiabator layer.
The design that safety cover of the present utility model adopts half chamber by two symmetries of mutual fastening to constitute; after installing thermal insulating material; the thermal insulating material that only needs two and half chambeies are fastened on the valve gets final product outward; install simple, convenient, fast; compare existing iron sheet, aluminium skin protected-type, installation work-hour can shorten 15 times.Owing to do not stay the slit after installing, foreign material are difficult for invading.During maintenance, only need take off two and half chambeies and get final product, and can not destroy safety cover, and safety cover can use repeatedly.On the two halves cavity edge, reserve the arc gap, be used to be nested with valve port.The connection in two and half chambeies can adopt the negative and positive button to be fastened and connected, and this mode is the most simple; Also can adopt to be provided with and attachment hole is set on flanging, the flanging and connects with screw at half cavity edge; Can also be hinged two and half chambeies on one side, another side is threaded.Can cover adiabator layer in advance at the two halves cavity wall, so just not need elder generation, directly can play effective insulation effect to the protection enclosure of band thermal insulating material of the present utility model and valve, elbow outward at valve, elbow outer wrapping thermal insulating material.Utilize this design, when the maintenance valve, can not destroy thermal insulation layer, can not cause environmental pollution.Safety cover of the present utility model can be made with the good resins such as 3301,196,197,198 of antiseptic property, wherein can add fire retardant, plasticizer.The safety cover of making is in light weight, anti-aging, convenient disassembly, and fire-retardant, anticorrosion, antiseepage, bending resistance, resistance to compression are not only easy to maintenance; also can use repeatedly, both saving of work and time reduced cost of investment again; be easy to apply, can have replaced disposable aluminium skin, iron sheet goods fully.

Embodiment
Embodiment 1, valve protective cap are made of half chamber 1,2 of two symmetries of mutual fastening, and the two halves cavity edge is provided with arc gap 3.Two and half chambeies are yin, yang two valve structures, and cloudy lobe 1 axial edge has the L shaped flanging 4 that turns up, and positive lobe 2 axial edge have the horizontal flanging 5 that turns up, and perpendicular distance equals perpendicular distance between the cloudy lobe two flanging vertical edge inner edges between 2 liang of hemmed edges of positive lobe.During use, yin, yang two lobes directly are fastened on the outer adiabator layer outside that covers of valve, rely on the elasticity of material own to fasten mutually.
In embodiment 2, the present embodiment, cloudy lobe 1 bottom L type flanging outer rim is provided with upwards rolls over hook 8, and positive lobe 2 lower horizontal flangings insert its inboard.Sun lobe 2 upper level flangings buckle in the L type flanging of cloudy lobe 1, and two flanging horizontal components are spirally connected fixing by bolt 6, nut 7.Other are with embodiment 1.
In embodiment 3, the present embodiment, lay one deck adiabator layer 9 on cloudy lobe 1, the positive lobe 2 two halves cavity walls, other are with embodiment 1.
