The utility model discloses a quick locking device solved current valve insulation cover dismouting trouble defect, the setting of thermovent, fundamentally eliminates because of the valve leaks the potential safety hazard of bringing, also can avoid simultaneously because of the valve leaks the various wastes that cause, makes the insulation material can used repeatedly, the heat preservation attenuation for whole product is light and handy pleasing to the eye more, also more is favorable to overhauing and the dismouting, because the shell surface area diminishes, has reduced heat radiating area, more is favorable to improving energy -conserving effect.
Description
Technical field
The utility model relates to valve heat insulation field, particularly a kind of split type valve insulating sleeve.
Background technique
The enterprises such as petrochemical industry, metallurgy, electric power, for energy-saving and cost-reducing and safety in production requirement, need to carry out isothermal holding to the High temperature valve of enterprises.Traditional heat preserving mode adopts mostly to be tied up thermal insulating material after needing the position of insulation to wrap up, then strikes with iron sheet or aluminium skin and make shell, is fixed on thermal insulating material outer shaping.
Along with the progress of science and technology, occur using glass fibre reinforced plastics casing to replace the valve insulating sleeve of iron sheet or aluminium skin.The internal structure of glass fibre reinforced plastics casing valve insulating sleeve is similar with employing conventional vacuum method, and topmost progress has changed iron sheet or aluminium skin shell into dismountable glass steel material shell.Shell generally more adopts " Hough " type (transliteration of English " half ", i.e. two half of meanings), uses stainless steel bolt two Lobelia chinensis to be connected into a closed entirety during installation.
Existing valve heat insulation technology, also exists following defect: 1, effectively can not prevent valve leak.Current valve heat insulation technology, all can not prevent the valve be incubated from leaking.Because the medium run in valve mostly is high temperature, volatile, poisonous and harmful substance, lagging after leaking, is caused to pollute and easily cause security incident; 2, energy-saving effect is undesirable.Can be used for the thermal-protective material of valve heat insulation at present, the problem that ubiquity thermal conductivity is larger, need thicker thermal insulation layer just can reach the surface heat flux standard of national requirements.And valve site is by the restriction of surrounding environment, especially for old device, does not often have enough spaces to meet thickness up to standard, cause the surface heat flux of valve heat insulation to exceed standard.Even if surface heat flux is up to standard, also exist because thermal insulation layer is blocked up, cause insulation external surface area large, cause the large problem of its heat radiation total amount and be unfavorable for energy-conservation.3, recycling rate of waterused is low.Current valve heat insulation technology, because protecting sheathing and thermal insulating material do not connect into entirety, carrying out in insulation disassembly process, insulating structure is damaged, can not reuse; In addition, reveal because of medium and cause thermal insulating material to lose efficacy, can not reuse; 4, checking maintenance is not easy to., by the restriction of its structure and construction process, there is the problem being not easy to dismounting in current valve heat insulation technology, duration urgent need when can not meet checking maintenance.

The purpose of this utility model is for the shortcoming existed in background technique and problem in addition improvement and bring new ideas, provides a kind of dismounting easy, can prevent the split type valve insulating sleeve of one leaked.
The technical solution of the utility model is a kind of split type valve insulating sleeve of structure, comprise main body cover, left outside shell, right casing, thermal insulation layer, described left outside shell, right casing are connected to left side and the right side of main body cover, three forms the hollow structure of a both-side opening, described thermal insulation layer is arranged on the internal surface of this hollow structure, and described main body cover, left outside shell, right casing are " Hough " type structure.
Wherein in an embodiment, described left outside shell, right casing is connected with main body cover by supporting member, described supporting member comprises dunnage, positioning ring, described dunnage is ring sheet structure, its inner circumference is provided with outstanding tongue piece, described positioning ring is columnar structured, an one base circumference has corresponding to dunnage tongue piece, with the projection of hole slot, hole slot described in described tongue piece inserts, dunnage is fixedly connected with positioning ring, described positioning ring is arranged on the internal surface of thermal insulation layer, dunnage is arranged on main body cover, left outside shell, the end face of right casing.
Wherein in an embodiment, described supporting member is that elastic metallic material is made.
Wherein in an embodiment, described main body cover is from symplex structure, described left outside shell, right casing are asymmetric fastening structure, and two one side of something are combined into an entirety respectively by quick-locking device or bolt by described main body cover, left outside shell, right casing.
Wherein in an embodiment, described thermal insulation layer is novel nano thermal insulating material and/or other high-performance thermal insulating materials.
Wherein in an embodiment, described thermal insulation layer and shell use stainless steel lag screws layering, misplacing is connected.
Wherein in an embodiment, described supporting member is provided with thermovent, described thermovent correspondence is arranged at the flange of insulation valve.
Wherein in an embodiment, described shell is the shaping PDCPD goods of DCPD-RIM.
The quick-locking device that the utility model adopts solves the troublesome defect of existing valve insulating sleeve dismounting; The setting of thermovent, ensure that under valve body air-proof condition, greatly reducing the temperature of valve flanges, fundamentally eliminating the potential safety hazard because valve leak brings, also can avoid the various wastes because valve leak causes simultaneously, thermal insulating material can be reused; Adopt current state-of-the-art nanometer heat insulating material, thermal conductivity is less, and thinner thermal insulation layer just can reach the surface heat flux standard of national requirements, and thermal insulation layer is thinning, makes whole product more lightly attractive in appearance, is also more conducive to maintenance and dismounting; Meanwhile, diminish because case surface is long-pending, decrease heat diffusion area, be more conducive to improving energy-saving effect.
