Abstract
The utility model discloses an anti-tempering valve set. When an oil tank and a pipeline used for conveying and storing flammable liquid and gas are on fire, a valve plug 3 of a valve 2 is operated to open by a valve switch lever handle 4, a valve plug set 6 of a liquid-gas-piping fire-resisting valve 5 is operated to close through the valve switch lever handle 4, the aflame liquid and gas are conveyed to a safe place through the valve plug set 6 so that the liquid and gas are not completely burnt. The anti-tempering valve set is characterized in that a valve joint 1 at one end of the valve 2 is fixedly integrated with a valve joint 1 at one end of the liquid-gas-piping fire-resisting valve 5, wherein the middle part of the valve 2 is composed of the valve plug 3 and the valve switch lever handle 4 for operating the valve plug 3; the other end of the valve 2 is connected with a pipeline for conveying and storing the flammable liquid and gas; the middle part of the liquid-gas-piping fire-resisting valve 5 is composed of the valve plug set 6 and the valve switch lever handle 4 for operating the valve plug set 6, the other end of the liquid-gas-piping fire-resisting valve 5 is connected with the pipeline for conveying and storing the flammable liquid and gas; the valve plug of the vale plug set 6 of the liquid-gas-piping fire-resisting valve 5 is manufactured by overlapping and fixing wire meshes.
Description
Technical field
The utility model is specifically related to petroleum gas emergency treatment technical field during breaking out of fire in the accumulating of jar bucket and pipeline.
Background technique
Know that with regard to the inventor oil is in the production accumulating at present both at home and abroad, it is that relatively effective measures take place in fire preventing that safety devices against fire is set.Safety devices against fire is widely used aborning and obtains having of good result: 1. back-fire relief equipment has safe fluid-tight, trapped well, flame trap, one-way valve, fire insulation valve etc., and its effect is to prevent that flame from swarming into equipment, pipeline or stoping flame to be expanded betwixt.2. explosion-proof relief equipment has safety valve, rupture disk (burst disk), blow-down pipe etc., is installed on the manufacturing mechanisms such as pressurized container, pipeline, and its effect has been the step-down explosion-proof.3. spark arrester.Be installed on the equipment and the device that produce Mars, its effect is to prevent the Mars inflammable matter that ignites that flies out.4. autodetector.Be used to detect objects such as combustable gas concentration, temperature, smog, its effect is when surpassing certain value (concentration), to report to the police automatically, starts the interlock automatic stopping and starts the self-extinguishing facility.Above-mentioned measure is no doubt important, in case take place to leak even burning, at first closes all valves, implements fire extinguishing; If blast, the state of affairs enlarges, the fire fighting difficulty strengthens.The utility model be exactly combine in above-mentioned former thereby a kind of way of breaking original routine is provided; It or not throttle down; But open valve, startup backfireproof valve group, the place of arriving safety through inflammable liquid gas delivery in the backfireproof valve group collection release combustion liquid.
Summary of the invention
The utility model is achieved in that described a kind of backfireproof valve group comprises: valve interface 1, valve 2, spool 3, valve switch bar handle 4, logical liquid vapour lock burning things which may cause a fire disaster valve 5, spool group 6.It is characterized in that: valve 2 and logical liquid vapour lock burning things which may cause a fire disaster valve 5 separately the valve interface 1 of an end be fixed together into as a whole; Wherein the middle part of valve 2 is made up of spool 3 and valve switch bar handle 4 structures of controlling spool 3, and the other end of valve 2 is connected with the pipeline pipeline of conveying with storage inflammable liquid gas; The middle part of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is made up of spool group 6 and valve switch bar handle 4 structures of controlling spool group 6, and the other end of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is connected with the pipeline pipeline of conveying with storage inflammable liquid gas; The spool of the spool group 6 of logical liquid vapour lock burning things which may cause a fire disaster valve 5 adopts the wire gaze stack fixedly to process.
The beneficial effect of the utility model is: can collect the aflame inflammable liquid gas of release through backfireproof valve group; Shorten period of combustion; Reduce and reduce in the combustion process and cause too much economic loss; The final result that can effectively avoid the combustion of liquid gaseous combustion totally just to be takes place, and the inflammable liquid of collecting also can utilize again.
Description of drawings
Accompanying drawing is a kind of backfireproof valve group schematic representation, Fig. 1 be inflammable liquid gas in the pipeline pipeline during normal the conveying through the plan view of backfireproof valve group, Fig. 2 be inflammable liquid gas plan view of process anti backfire valve group during normal conveying the in the pipeline pipeline; 1. valve interfaces wherein; 2. valve, 3. spool, 4. valve switch bar handle; 5. logical liquid vapour lock burning things which may cause a fire disaster valve, 6. spool group.
Embodiment
Form instance below in conjunction with accompanying drawing ball valve and butterfly valve explains further details to the utility model; Say that like accompanying drawing a kind of backfireproof valve group of showing is on the pipeline pipeline of conveying and storage inflammable liquid gas, to install; When inflammable liquid gas is normally carried in the pipeline pipeline; The spool 3 of valve 2 is controlled through valve switch bar handle 4 and is opened, and the spool group 6 of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is controlled and can be opened through valve switch bar handle 4; When normal storage stopped to carry, the spool 3 of valve 2 was controlled through valve switch bar handle 4 and is closed; When carrying and when the oil tank of storage inflammable liquid gas and the breaking out of fire of pipeline pipeline; The spool 3 of valve 2 is controlled through valve switch bar handle 4 and is opened; The spool group 6 of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is controlled through valve switch bar handle 4 and is closed; Let aflame liquefied gas be transported to safe place through spool group 6, not allowing its burning totally just is to close spool group 6 shown in Fig. 2 dotted line; It is characterized in that: valve 2 and logical liquid vapour lock burning things which may cause a fire disaster valve 5 separately the valve interface 1 of an end be fixed together into as a whole; Wherein the middle part of valve 2 is made up of spool 3 and valve switch bar handle 4 structures of controlling spool 3, and the other end of valve 2 is connected with the pipeline pipeline of conveying with storage inflammable liquid gas; The middle part of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is made up of spool group 6 and valve switch bar handle 4 structures of controlling spool group 6, and the other end of logical liquid vapour lock burning things which may cause a fire disaster valve 5 is connected with the pipeline pipeline of conveying with storage inflammable liquid gas; The spool of the spool group 6 of logical liquid vapour lock burning things which may cause a fire disaster valve 5 adopts the wire gaze stack fixedly to process.
