Description
Technical field
The utility model relates to a kind of water-sealing valve, relates in particular to a kind of water replenishing device that is used for gas pipe line fast shut-off coal gas water-sealing valve.
Background technique
The present both at home and abroad gas pipe line water-sealing valve that extensively adopts of metallurgy industry, it is simple in structure, easy to make, expense is little, easy to operate, can cut off coal gas reliably.Its shortcoming is; When coal gas is cut off in water shutoff, for guaranteeing the safety of shutoff coal gas, adopt a large amount of overflow waters to guarantee effective partition coal gas of water seal, its consequence is that waste water resource causes problems such as environmental pollution, when pipeline pressure fluctuates, if the water in the water-sealing valve also has little time supply, can cause the water-sealing valve water shutoff to lose efficacy, cause accident to leak the coal gas.
Chinese patent publication number CN03228620.1 discloses a kind of gas pipe line water seal shut-off means, on partial structurtes, optimized water-sealing valve, its function is: the height according to water level in water-sealing valve water shutoff process is implemented automatic water supplement, avoid the pollution of water resource waste and environment, can satisfy the nominal situation of coal gas water seal., when water-sealing valve drain pipe or waste pipe generation burn into leak etc., just may cause the problem of gas leakage.
According to Fig. 1 the detailed problem of the prior art is described, among Fig. 1: 1. being gas pipe line water-sealing valve bodies, 2. is supply pipes, 3. is automatic water-replenishing devices, 4. is waste pipes, 5. is water seal drain pipes, 6. is hydathodes, 7. is contact shut-off meanss.Its working principle is, pipeline will cut off coal gas, will get in touch with shut-off means 7 and close, and in the pipe of water-sealing valve 1, by supply pipe 2 water fillings, water shutoff, is discharged by waste pipe 4 through automatic water-replenishing device 3 through water seal drain pipe 5 hydathode 6 of flowing through.When water seal reaches the effective height of water shutoff, brought into play the effect of cutting off coal gas, just close the valve of supply pipe 2, because variation in pressure causes lack of water, automatic water-replenishing device 3 is just implemented moisturizing, plays the purpose of water saving in the water shutoff process.When water-sealing valve need connect coal gas, open the water in contact shut-off means 7 discharge pipings, reach the purpose of ventilating coal gas, and the condensed water in the coal gas relies on hydathode 6 to discharge through contact shut-off means 7.
This key issue wherein is, automatic water-replenishing device 3 is to carry out moisturizing by waste pipe 4 and water seal drain pipe 5, has changed the mode of former water seal from supply pipe 2 moisturizings, so the moisturizing ability reduced, anti-gas pressure fluctuation ability drop; When water-sealing valve drain pipe or waste pipe generation burn into situation such as leak, the ability that moisturizing enters the water seal body further descends, if do not stop the leakage of water shutoff, causes the leakage of coal gas the most at last.
