Abstract
The utility model relates to a safety partition device of the low pressure fuel gas pipeline, in particular to a safety partition device of the low pressure fuel gas pipeline which is safe, reliable and applied; and the utility model consists of a butterfly valve, a blind plate and a water sealed fuel gas pipeline which are connected in serial; bleeders are arranged at the front and the back of the blind plate and the water sealed fuel gas pipeline; the bottom of the water sealed fuel gas pipeline is connected with a communicating vessel which is connected with a drain apparatus, and the drain apparatus is connected with an admitting pipe and a drain pipe; a water seal overflow pipe is arranged at the water seal, a water seal pipe and a shutdown valve are arranged at the overflow pipe; and the drain pipe and the bottom of the water seal overflow pipe are connected to a drainage ditch. There by the utility model is capable of ensuring the low pressure fuel gas can be cut off reliably, and when the blind plate and the water seal is in the fault, the utility model is capable of maintaining and detecting the low pressure fuel gas equipments in time, thereby guaranteeing the normal use of the low pressure fuel gas equipment, reducing the release of the flue gas and eliminating the potential safety hazard.
Description
Technical field
The utility model relates to the low-pressure fuel gas pipe safety partition apparatus of low-pressure fuel gas pipe safety partition apparatus, particularly a kind of safe and reliable practicality.
Background technique
Along with going deep into of industry energy conservation consumption reduction work, the low-pressure fuel gas that originally diffused as: blast furnace gas, coal gas of converter, coke-stove gas, garbage category sludge gas etc. are used as a kind of energy by enterprise, and between each combustion gas user, between the same combustion gas user distinct device combustion gas frequency of utilization, overhaul of the equipments time have nothing in common with each other, therefore need a kind of combustion gas partition apparatus.But the employing butterfly valve that has of this partition apparatus adds water seal at present, so sometimes, cause the water in the water seal to be bled off unintentionally, the harm personal safety, simultaneously, therefore can not guarantee to use the normal use of gas-fired equipment and cause diffusing of combustion gas sometimes because water seal and associated pipe and facility break down and can't in time carry out Maintenance and Repair to fix a breakdown; The employing butterfly valve blank off (or push-pull valve, glasses valve etc.) that has, in case and blind plate (or push-pull valve, glasses valve) etc. is can't operate owing to the reason of equipment itself or corrosion etc. the time, cause the equipment of scheduled overhaul in time to overhaul, cause equally and use gas-fired equipment normally not use, cause and give out of gas, both caused the waste of the energy, again befouling environment.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, and a kind of low-pressure fuel gas pipe safety partition apparatus is provided, and satisfies the needs of low-pressure fuel gas partition and equipment pipe Maintenance and Repair.
The purpose of this utility model realizes by the following technical solutions, low-pressure fuel gas pipe safety partition apparatus is formed through the gas pipeline serial connection by butterfly valve, blind plate, water seal, gas pipeline after blind plate front and back and the water seal is provided with exhaust stack, be connected with connecting vessels in the water seal bottom, connecting vessels connects hydathode, connects intake pipe and waste pipe on the hydathode.Water seal is provided with the water seal spill pipe, and spill pipe is provided with water sealing (sealing water) pipe and shut-off valve.The hydathode connecting vessels is provided with isolating valve.The gutter is inserted in the lower end of waste pipe and water seal spill pipe.
Because having adopted above technological scheme, low-pressure fuel gas pipe safety partition apparatus of the present utility model to solve butterfly valve blank off or butterfly valve adds the potential safety hazard that the water seal partition apparatus causes and can't in time safeguard and timely maintenance issue.The low-pressure fuel gas pipe safety partition apparatus that the utility model provides, both can guarantee the reliable partition of low-pressure fuel gas, again can be to using low-pressure fuel gas equipment in time to carry out Maintenance and Repair when blind plate (or push-pull valve, glasses valve etc.) or water seal fault, thereby guarantee to use the normal use of low-pressure fuel gas equipment, minimizing gives out of gas, and gets rid of potential safety hazard.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings, as shown in the figure, low-pressure fuel gas pipe safety partition apparatus, include butterfly valve 1, blind plate 2 (or push-pull valve, glasses valve etc.), the water seal 3 of serial connection successively on the low-pressure fuel gas pipeline, bottom in water seal 3 is connected with hydathode connecting vessels 6, is provided with isolating valve 10 in connecting vessels 6.Industry water enters hydathode 5 by intake pipe 4, in water seal 3, be provided with water seal spill pipe 7, the water seal spill pipe is provided with shut-off valve 11, the water seal height that the height may command needs that is provided with by the water seal spill pipe, on the gas pipeline after blind plate (or push-pull valve, glasses valve etc.) 2 front and back and the water seal, be provided with gas pipeline exhaust stack 8, with the combustion gas in the discharge conduit.The gutter is inserted in the lower end of waste pipe 9 and water seal spill pipe 7.
The low-pressure fuel gas pipe safety partition apparatus that the utility model provides when the low-pressure fuel gas pipeline need cut off, is shut butterfly valve and blind plate (or push-pull valve, glasses valve etc.), with the water seal fills with water, low-pressure fuel gas can be cut off fully.In the time can't operating, also can open the partition effect by butterfly valve and water seal because of blind plate (or push-pull valve, glasses valve etc.) fault.Therefore can in time carry out combustion gas user's plant maintenance maintenance, know blind plate (or push-pull valve, glasses valve etc.) existing problems simultaneously, can arrange in the lump when external maintenance is overhauled afterwards.And when water seal associated pipe or facility break down, can play the partition effect by butterfly valve and blind plate (or push-pull valve, glasses valve etc.), therefore can in time the fault of water seal associated pipe or facility appearance be safeguarded, to fix a breakdown.Shut-off valve and isolating valve play when low-pressure fuel gas normally uses with extraneous and cut off, and prevent that low-pressure fuel gas from leaking.
