Abstract
The utility model relates to a T-shaped heat preservation sleeve of a common powder insulation storage tank drain valve, wherein the T-shaped heat preservation sleeve can be used for conducting not only good heat preservation on a low-temperature valve but also effective chilling shrinkage compensation on a drain pipe. The T-shaped heat preservation sleeve comprises a bellows cover, mineral cotton, a T-shaped heat preservation barrel and an expansion joint. The low-temperature valve is wrapped in the T-shaped heat preservation barrel which is filled with the mineral cotton, the hand wheel end of the low-temperature valve is sealed through the bellows cover and the T-shaped heat preservation barrel, and chilling shrinkage compensation is conducted on the drain pipe through the expansion joint. The T-shaped heat preservation sleeve has the advantages that the structure is simple; when the low-temperature valve is maintained, dismounting is convenient, and maintenance is convenient; a heat preservation effect is good; chilling shrinkage compensation is achieved.
Description
Technical field
The utility model relates to one and both low temperature valve was well incubated, again can be low to the effective shrinkage compensation of liquid-discharging tube and cost, overhaul the T-shaped insulation sleeve of ordinary powder heat insulation storage tank liquid discharging valve easily, and belong to heat insulation storage tank liquid discharging valve lagging and manufacture field.
Background technique
Because low temperature hopper liquid discharging valve needs insulation at low temperatures, in the time of cryogenic pipelines shrinkage, need compensation simultaneously.And existing ordinary powder heat insulation storage tank tapping line adopts the form of vacuum pipeline and vacuum and low temperature valve.Its deficiency: complex structure, vacuum pipeline and the vacuum valve cost of vacuum pipeline are expensive, needs vacuum tube replacing all day, maintenance difficult when vacuum valve maintenance.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, design one is not only to the good insulation of low temperature valve but also can to the effective shrinkage compensation of liquid-discharging tube and cost simple in structure is low, valve overhauls the T-shaped insulation sleeve of ordinary powder heat insulation storage tank liquid discharging valve easily.
Design proposal: in order to realize above-mentioned purpose of design.The utility model, in structural design, adopts the design of T-shaped insulation sleeve and expansion joint, is technical characteristics of the present utility model.The object of doing is like this: owing to being provided with on sleeve, bellows cover is connected with Subzero valve, be filled with slag wool in T-shaped sleeve is incubated, good insulation, the maintenance that can meet common powder heat insulation storage tank liquid discharging valve are convenient, again can be to the effective shrinkage compensation of liquid-discharging tube, the deficiency of fundamentally avoiding background technique to exist.
Technological scheme: the T-shaped insulation sleeve of a kind of ordinary powder heat insulation storage tank liquid discharging valve, comprise bellows cover, slag wool, T-shaped heat-preservation cylinder, expansion joint composition, Subzero valve is wrapped in T-shaped insulation sleeve, and fill slag wool in T-shaped insulation sleeve, Subzero valve handwheel end overlaps and T-shaped insulation sleeve seal by bellows, and tapping line carries out cold shrinkage-compensating by expansion joint.
The utility model compared with background technique, the one, simple in structure; The 2nd, for convenience detach when low temperature valve is overhauled, maintenance is convenient; The 3rd, high insulating effect; The 4th, shrinkage compensation.
Brief description of the drawings
Fig. 1 is the T-shaped lagging barrel structure of ordinary powder heat insulation storage tank liquid discharging valve schematic diagram.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The T-shaped insulation sleeve of a kind of ordinary powder heat insulation storage tank liquid discharging valve, comprise that bellows cover 1, slag wool 2, T-shaped heat-preservation cylinder 3, expansion joint 4 form, Subzero valve is wrapped in T-shaped insulation sleeve 3, and at the interior filling slag wool 2 of T-shaped insulation sleeve 3, Subzero valve handwheel end overlaps 1 by bellows and seals with T-shaped insulation sleeve 3, tapping line carries out cold shrinkage-compensating by expansion joint 4, and its preparation process is prior art, is not described herein at this.
It is to be understood that: although above-described embodiment is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of restriction to model utility mentality of designing; any combination, increase or amendment that does not exceed the utility model mentality of designing, all falls in protection domain of the present utility model.
