Abstract
The utility model discloses the fire-retardant detonation seal of a kind of natural gas tempering, comprise body, body two ends adpting flange, body is all provided with wire netting one at two ends and flange connections, and wire netting one is provided with fusible alloy, body is also provided with wire netting two in centre, wire netting two is also provided with fusible alloy, wire netting one and wire netting two is provided with ventilating microhole, in body, is provided with check valve, check valve connects stage clip, check valve is provided with the passage that can communicate with body.The fire-retardant detonation seal of tempering of the present utility model all arranges wire netting and fusible alloy at the two ends of body and centre, and when generation tempering, produce high temperature and melted by fusible alloy, the ventilating microhole of wire netting is blocked by the alloy after thawing, thus is blocked by pipeline; If blast generation gases at high pressure, back down on the check valve be connected on stage clip, after check valve backs down, passage just and obstructed between body, has cut off gas supply, has avoided burning and blast simultaneously.
Description
Technical field
The utility model relates to a kind of fire-retardant explosion arrestment device, the particularly fire-retardant explosion arrestment of natural gas tempering.
Background technology
In the use procedure of natural gas or liquefied petroleum gas, because misoperation tempering can occur, thus the situation of burning, exploding, fire-retardant explosion arrestment device is exactly burning in order to prevent from occurring during tempering, blast, the general fire-retardant detonation seal adopted generally adopts check-valves to stop the tempering of flame now, but flame retardant effect is bad, tempering sometimes still can not be stoped to enter pipeline and equipment, easily burn, explode.
Utility model content
The purpose of this utility model is to provide one not only fire-retardant but also explosion arrestment, and the fire-retardant detonation seal of effective tempering, tempering effectively can be stoped to enter pipeline and equipment, avoid burning and blast.
The technical solution of the utility model is as follows:
The fire-retardant detonation seal of a kind of natural gas tempering, comprise body, body two ends adpting flange, body is all provided with wire netting one at two ends and flange connections, and wire netting one is provided with fusible alloy, body is also provided with wire netting two in centre, wire netting two is also provided with fusible alloy, described wire netting one and wire netting two is provided with ventilating microhole, in described body, is provided with check valve, check valve connects stage clip, check valve is provided with the passage that can communicate with body.
Described flange is band neck W.N flange.
The fire-retardant detonation seal of tempering of the present utility model all arranges wire netting and fusible alloy at the two ends of body and centre, when the flame generation tempering of combustion of natural gas time, produce high temperature to be melted by fusible alloy, the ventilating microhole of wire netting is blocked by the alloy after thawing, thus is blocked by pipeline; If simultaneously natural gas is blasted generation gases at high pressure, by on the check valve top that is connected on stage clip, and the passage on original check valve communicates with body, after on check valve top, passage just and obstructed between body, has cut off gas supply, so just be equivalent to twice insurance, two places block pipeline, extinguish tempering, avoid burning or blast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the fire-retardant detonation seal of a kind of natural gas tempering, comprise body 1, body 1 two ends adpting flange 2, body 1 is all provided with wire netting 1 at two ends and flange 2 junction, wire netting 1 is provided with fusible alloy 31, body 1 is also provided with wire netting 24 in centre, wire netting 24 is also provided with fusible alloy 41, described wire netting 1 and wire netting 24 are provided with ventilating microhole, be provided with check valve 5 in body 1, check valve 5 connect stage clip 6, check valve 5 is provided with the passage that can communicate with body 1.Fire-retardant detonation seal is connected in natural gas line by the flange 2 at two ends, and flange 2 adopts band neck W.N flange, and the welding performance of W.N flange is relatively good, corrodes smaller, and resistance to pressure is better simultaneously, is not easy to reveal.When the flame generation tempering of combustion of natural gas time, produce high temperature and melted by fusible alloy, the ventilating microhole of wire netting is blocked by the alloy after thawing, thus is blocked by pipeline, cuts off gas supply, extinguishes tempering; If simultaneously natural gas is blasted generation gases at high pressure, by on the check valve top that is connected on stage clip, and the passage on original check valve communicates with body, after on check valve top, passage just and obstructed between body, cut off gas supply, be so just equivalent to twice insurance, two places block pipeline, one place is the ventilating microhole blocked after alloy melts on wire netting, one place be on check valve top after passage just and obstructed between body, blocked gas circuit, avoided burning and blast.In natural gas main pipeline, branch pipe(tube), all arrange the fire-retardant detonation seal that bore is different, form multistage fire-retardant explosion arrestment, fire-retardant detonation seal is all arranged to plumbness in the duct, and the ventilating microhole of wire netting can be blocked after melting by such alloy preferably.
