The upper part of the left pipeline of the communicating type water level controller is provided with a gas pipeline, the inlet of the gas is arranged on the upper part, the outlet of the gas is arranged on the side, the side of the left pipeline of the communicating type water level controller is provided with the dirt discharge valve and a water level gauge, and the bottom is provided with the automatic water replenishing device and the water inlet in emergency. The utility model has the characteristics of simple structure, convenient maintenance and operation, low manufacturing cost, and reliable operation. The time interval of the cutting and the opening of the gas can be set according to the requirement; the action time is short, and the cutting and the opening can be completed within one to three seconds.
Description
Technical field
The utility model is to be the regenerative combustion system capital equipment of fuel with hot and cold producer gas, is the fast shut-off coal gas of property performance period on its gas piping and the device of opening coal gas.Need also to can be applicable to periodically fast shut-off and the other field of opening coal gas.
Background technology
Be that the combustion system gas piping of the stoves such as heat accumulating type heater for rolling steel of fuel all adopts mechanical repid cut-off valve with cold and hot producer gas in the past, owing to bondings such as the tar in the coal gas, dust, pile up, cause that to cut valve soon malfunctioning, can not cut off coal gas, and cause coal gas loss, contaminated environment, and the explosion danger of hiding, thereby stove is forced to stop production, maintenance, the stove operating rate is low, and influence is produced, and dangerous.
The utility model content
The purpose of this utility model provides and a kind ofly solves that the in-problem manufacturing of prior art is simple, good airproof performance, the safe and reliable cold and hot producer gas fast shut-off of hydrolock device.
For achieving the above object, the utility model is realized by following scheme:
The cold and hot producer gas fast shut-off of hydrolock device, it is characterized in that: the utility model is by cylinder, communication type water level controller, automatic water replenishing device, emergence compensating water device, blowoff valve, level control valve, coal gas is introduced extraction channel and is constituted, the communication type water level controller is continuous the forming of two pipelines that the bottom communicates, in water seal water is housed, be provided with the driving cylinder in the right side conduit upper, drive in the cylinder and be provided with piston rod, link to each other with communication type water level controller right side pipeline inner carrier, be provided with manual level control valve in the pipeline side; Conduit upper is provided with gas piping in the left side of communication type water level controller, and at the welded top end plate, the end plate perforate is provided with gas entry, is provided with water collar around the pipeline, and gas exit is located at the left side conduit upper of communication type water level controller; Be provided with blowoff valve and water level meter in pipeline side, the left side of communication type water level controller, be provided with automatic water replenishing device and emergent water inlet in the bottom.
Wherein the coal gas introduction tube is one, but coal gas draw the outlet can be more than two.Promote piston by cylinder and move back and forth rising of water level controller middle water level or decline, the effect that reaches cut-out coal gas and connect coal gas of making on time.
The utility model advantage compared with prior art is: this device can be used for the gas piping realization fast shut-off of two above burners, and the former valve of cutting soon can only be used for a gas piping fast shut-off of firing mouth; Owing to adopt water seal, eliminated the former valve of cutting soon owing to tar, dust bonding, make the phenomenon of its cisco unity malfunction, and can remove part tar and dust; This device has simple in structure, safeguards, easy to operate, and low cost of manufacture, reliable characteristics can be set the time interval of cutting off and connecting coal gas as required, and actuation time is short, only needs 1-3 can finish second to cut off or open-minded.
Description of drawings
Fig. 1 is the schematic diagram of structure of the present utility model
The specific embodiment
See Fig. 1, the utility model is by cylinder 1, communication type water level controller 2, automatic water replenishing device 9, emergence compensating water device 7, blowoff valve 6, level control valve 8, coal gas is introduced extraction channel and is constituted, communication type water level controller 2 is continuous forming of two pipelines that the bottom communicates, in water seal water 11 is housed, be provided with in the right side conduit upper and drive cylinder 1, drive in the cylinder and be provided with piston rod, link to each other with communication type water level controller right side pipeline inner carrier 12, be provided with manual level control valve 8 in the pipeline side.Conduit upper is provided with gas piping 13 in the left side of communication type water level controller, at welded top end plate 3, end plate 3 perforates are provided with gas entry, are provided with water collar 5 around the gas piping 13, gas exit 4 is located at the left side conduit upper of communication type water level controller, and gas exit can be 2～4.Be provided with blowoff valve 6 and water level meter 10 in pipeline side, the left side of communication type water level controller, be provided with automatic water replenishing device 9 and emergent water inlet 7 in the bottom.
Cylinder moves downward and drives the setting-out piston, when water level in the pipe of the left side in the communication type water level controller is increased to maximum water level among the figure, with the coal gas shutoff in the coal gas introduction tube, realizes cutting off; Left side communicating pipe water level dropped to the lowest water level line when cylinder moved upward, and coal gas introduction tube and fairlead are connected, and moved back and forth by the time interval of setting, and realized the cut-out and the connection of coal gas.By time relay setting-up time, the water level of control communication type water level controller raises (cut-out coal gas), and water level descends (pressing ventilating coal gas), and synchronous the same period with the commutation of the reversal valve of heat accumulating type coal burning system.
Because of containing more coal tar and dust among the coal gas, part enters in the water seal water, and available blowoff valve is regularly removed.
