Abstract
The utility model relates to a both had good rain -proof, sand prevention, prevented the bird effect, had the ordinary rain -proof cap of powder isolation storage tank top drain of simple structure, practicality again, constituteed by drum, roof fall, mount and silk screen, weld into latticedly with silk screen and drum top, drum and roof fall are connected to four mounts and to weld the unloading mouth of pipe terminal. The advantage: firstly, simple structure, secondly, practical, thirdly, there be good rain -proof, sand prevention, prevent the bird effect, fourthly, to mouthful non -resistance of releasing.
Description
Technical field
The utility model relates to and had a kind ofly both had good rainproof, sand prevention, anti-bird effect, has again the powder isolation storage tank top drain rainhat that structure is simple, practical, belongs to heat insulation storage tank emptying rainhat and manufacture field.
Background technology
Because cryogenic liquid tank can cause internal container pressure superpressure in operation, for ensureing that endogenous pyrogen can work under design condition, internal container pressure relief device need be set, can damage operating area personnel for exempting from pressure relief device exit, pressure relief device outlet need be guided to certain altitude with pipeline and release, the gas of releasing out is low-temperature condition, for preventing pipeline internal water accumulation, the blocking pipe that freezes is there is after meeting cryogenic gas, build-up of pressure cannot be released, so need install rainhat at the pipeline top of drawing.Normally used rainhat has two kinds of structures: the tapered crown of a kind of directly employing is connected with pipe with fixed mount, pipeline pressure release non-resistance, and shortcoming is when there being wind, and sand and rainwater can enter in pipe in the same old way; One adopts vexed plate to be connected with pipe with hinge, utilizes vexed plate weight to seal, like this can effectively rainwater-proof and dust storm, and shortcoming runs up to certain pressure in pipeline just can back down vexed plate, and pressure release is delayed, and pressure release resistance is large.
Summary of the invention
Design goal: avoid the weak point in background technology, designs and had a kind ofly both had good rainproof, sand prevention, anti-bird effect, have again the powder isolation storage tank top drain rainhat that structure is simple, practical.
Design plan: in order to realize above-mentioned design goal.1, the object adopting silk screen to be welded into fenestral fabric at barrel top is: realize gear bird function.2, four fixed mounts are adopted cylinder (sand-proof effect) and crown (rainproof effect) to be combined, finally be soldered to emptying mouth of pipe end, the object done like this is: can meet that ordinary powder heat insulation storage tank drain is rainproof, sand prevention, anti-bird demand, the weak point can fundamentally avoiding background technology to exist again.
Technical scheme: a kind of powder isolation storage tank top drain rainhat, is characterized in that being made up of cylinder, crown, fixed mount and silk screen; Be welded into latticed with silk screen and barrel top, cylinder and crown carry out being connected and are soldered to emptying mouth of pipe end by four fixed mounts.
The utility model is compared with background technology, and one is that structure is simple; Two is practical; Three is have good rainproof, sand prevention, anti-bird effect; Four is to bleed outlet non-resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of powder isolation storage tank top drain rainhat.
Fig. 2 is the birds-eye view of this structure.
Detailed description of the invention
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of powder isolation storage tank top drain rainhat, is made up of cylinder 1, crown 2, fixed mount 3 and silk screen 4; Become latticed with silk screen 4 with cylinder 1 welded top, cylinder 1 carries out being connected with crown 2 and is soldered to emptying mouth of pipe end by four fixed mounts 3.Cylinder and crown combine by four fixed mount 3 intervals in 90 °, and its manufacture craft system prior art, is not described herein at this.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to the utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
Claims (2)
1. a powder isolation storage tank top drain rainhat, is characterized in that being made up of cylinder (1), crown (2), fixed mount (3) and silk screen (4); Become latticed with silk screen (4) with cylinder (1) welded top, cylinder (1) carries out being connected with crown (2) and is soldered to emptying mouth of pipe end by four fixed mounts (3).
