Abstract
The utility model relates to a flange valve insulation cover whose housing is divided into two halfs, (1-1) and (1-2), and has a thermal insulation layer (2). The housing is provided with outlets corresponding to the inlet and outlet of the valve and a valve stem. A flat flange edge (3-1) is outstretched along an upper and lower meshing edge of the half (1-1), and a reverse flange edge (3-2) which can contain the flat flange edge (3-1), is outstretched from the other half (1-2). A bolt hole (4) is arranged on the flange. The outside of the thermal insulation layer (2) is provided with a metal mesh layer (6) whose mesh edge is connected on a plurality of needling screws (7) arranged on the housing. The utility model is strong in adaptability, more convenient to install and disassemble and firm in combination.
Description
Technical field
The utility model relates to a kind of flange-type valve lagging.
Background technique
Traditional valve heat preservation technology, general mineral substance or the chemical fibre material with heat-shielding performance that adopt of liner, shell then adopt tin plate or aluminium skin on-site consolidation overlap joint to form.This valve sleeve technology can't guarantee, thermal insulating material or gage distortion, or occur blankly, make thermal insulation property very not good.The 2nd, when each maintenance, this valve sleeve must be removed fully, becomes refuse, causes the very big waste of manpower and goods and materials.Chinese patent literature CN2031057 discloses a kind of " valve lagging ", and shell is divided into two and half shells, and adiabator layer is arranged in the shell, two and half shell lower hinge, and there is locking device at the upper opening place.Whole lagging is resolved into two and half shells, simplified processing, can also make the lagging shape valve profile of more fitting, and can be repeatedly used.But, make installation and removal still convenient inadequately because its two halves still connect.And, also there is it and overlaps the not enough and difficult fixing problem of shape of combination force because thermal insulating material is more fluffy.
Summary of the invention
The purpose of this utility model is, a kind of flange-type valve lagging is provided.
The utility model is a flange-type valve lagging, shell is divided into two Houghs (half shell), adiabator layer is arranged in the shell, shell has with valve imports and exports corresponding outlet, it is characterized in that one of them Hough is projected with flat mouthful flange edge along the limit that combines between the higher and lower levels, another Hough is projected with the anti-mouthful of flange edge that can comprise flat mouthful flange, and bolt hole is arranged on the flange.The utility model two Houghs are independent fully, and volume is little, and the installation and removal in small space are more convenient; Adopt fastening piece between two Houghs, adaptability is strong, in conjunction with firm.
Described sheathing material should have shock resistance, anti-aging, and anti-acid and alkali corrosion and characteristic such as fire-retardant can be (as iron sheet, the aluminium skins etc.) of metal, or nonmetallic (as glass fibre reinforced plastics, high strength plastics etc.).Thermal insulating material can be an alumina silicate, rock wool and glass wool etc.
Between described shell and the adiabator layer adhesive-layer is arranged, to strengthen the combination force of itself and shell.Outside adiabator layer, also be provided with oven wire mesh blanket, selvage is connected in some thorns that shell is provided with and nails on, given thermal insulating material with a solid shape that relatively coincide with valve, improved thermal insulation property, prevented that also lagging adiabator layer when mounting or dismounting from coming off, pulverizing.
The utility model also has adaptability strong except beautiful shape, and good heat insulating mounts and dismounts conveniently, in conjunction with firm advantage, is a kind of outstanding and practical product.

Fig. 2 is a schematic top plan view of the present utility model;
Fig. 3 is that the A of Fig. 1 is to (to be assembled) schematic representation;
Fig. 4 is embodiment's 2 schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1, sees Fig. 1,2,3.This example is the lagging of band valve rod valve, it has a glass fibre reinforced plastics casing 1, shell is divided into two Hough 1-1 and 1-2, shell has with valve to be imported and exported and the corresponding outlet of valve rod, one of them Hough 1-1 is projected with flat mouthful of flange 3-1 along the limit that combines between the higher and lower levels, another Hough is projected with the anti-mouthful of flange 3-2 that can comprise flat mouthful flange, and upper flange has 8 pairs of stainless steel bolts 4, and lower flange has 6 pairs of stainless steel bolts 4.Between shell 1 and the adiabator layer 2 anti-flaming viscose layer 5 is arranged.This example also is provided with the steel screen layer 6 that matches with its shape outside adiabator layer, along being provided with some caltrops 7 on the shell on adiabator layer limit, the limit respective hook of silk screen 6 is connected on the caltrop 7.
Embodiment 2.This example is the lagging of safety check, and except no valve rod, all the other the same examples are seen Fig. 4.
Claims (3)
1, a kind of flange-type valve lagging, shell is divided into two Houghs (1-1) and (1-2), adiabator layer (2) is arranged in the shell, shell has with valve imports and exports corresponding outlet, it is characterized in that one of them Hough (1-1) is projected with flat mouthful flange edge (3-1) along the limit that combines between the higher and lower levels, another Hough (1-2) is projected with the anti-mouthful of flange edge (3-2) that can comprise flat mouthful of flange edge (3-1), and bolt hole (4) is arranged on the flange.
2, flange-type valve lagging according to claim 1 is characterized in that between described shell (1) and the adiabator layer (2) adhesive-layer (5) being arranged.
