Abstract
The utility model relates to a timing valve for a gas pipeline. The utility model is mainly comprises an air inlet tube, an air outlet tube, an air inlet passage, a sealed air chamber, a timing controller, a pressure spring, a control rod, and sealing rings. The utility model is characterized in that when flame of a gas burner goes out because of wind, water, etc., the utility model can cut off gas sources according to the given time, and consequently, accidents are avoided. The utility model has the advantages of simple structure, low cost, and convenient operation.
Description
The utility model relates to a kind of gas pipe line Timed valve.
Existing gas pipeline is that coal gas is delivered directly on the gas ring, and when the flame on the gas ring extinguished because of factors such as wind, water, coal gas continued to leak, and can cause accidents such as personnel poison, fire.
The purpose of this utility model is a kind of valve that can regularly close coal gas of design.
The utility model is achieved in that a kind of gas pipe line timing control valve, comprise timing controller 13, seal ring 4, seal ring 10, stage clip 9, swivel nut 16, cone valve 3, it is characterized in that: suction tude 6 is connected with suction port 5 on the housing 1, steam outlet pipe 17 is connected with air outlet 18 on the housing 1, sealed air chamber 8 communicates with suction port 5 by intake duct 7, sealed air chamber 8 communicates with air outlet 18 by air outlet 2, the bottom 14 that the centre is provided with through hole joins with swivel nut 16, the lower thread of the sealed air chamber 8 on swivel nut 16 and the housing 1 is connected, timing controller 13 is connected with bottom 14, the controlling rod 11 of hand valve 12 is housed by an end of timing controller 13 controls, the other end is provided with cone valve 3, the platform 15 that cone valve 3 belows are provided with is held seal ring 4, controlling rod 11 is contained in the through hole on the bottom 14 in mobilizable mode, by swivel nut 16 tapering of cone valve 3 is stuck on the air outlet 2, seal ring 10 is contained on the bottom 14, and stage clip 9 is sleeved on the controlling rod 11.
Advantage of the present utility model is: can be by timing controller 13 control controlling rods 11 by the preset time of throttle down on time, thus can avoid accidents such as the gas leakage personnel that cause poison, fire to take place.
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing as can be known, suction tude 6 is connected with suction port 5 on the housing 1, steam outlet pipe 17 is connected with air outlet 18 on the housing 1, sealed air chamber 8 communicates with suction port 5 by intake duct 7, sealed air chamber 8 communicates with air outlet 18 by air outlet 2, the bottom 14 that the centre is provided with through hole joins with swivel nut 16, the lower thread of the sealed air chamber 8 on swivel nut 16 and the housing 1 is connected, timing controller 13 is connected with bottom 14, the controlling rod 11 of hand valve 12 is housed by an end of timing controller 13 controls, the other end is provided with cone valve 3, the platform 15 that cone valve 3 belows are provided with is held seal ring 4, and controlling rod 11 is contained in the through hole on the bottom 14 in mobilizable mode, by swivel nut 16 tapering of cone valve 3 is stuck on the air outlet 2, seal ring 10 is contained on the bottom 14, and stage clip 9 is sleeved on the controlling rod 11.
During use, with hand dextrorotation hand valve 12, screw rod platform 15 on the controlling rod 11 presses down stage clip 9, after air outlet 2 certain distances are left in the tapering of cone valve 3, timing controller 13 regularly 30 minutes, and making controlling rod 11 location, coal gas enters steam outlet pipe 17 through suction tude 6, suction port 5, intake duct 7, sealed air chamber 8, air outlet 2, air outlet 18, can light gas ring.
After the flame on the gas ring extinguishes because of wind, water or other reason, just cause gas leakage, after timing controller 13 reaches preset time, just control controlling rod 11 and throw off locking, controlling rod 11 top screw rod platform 15 under the tension force effect of stage clip 9, the tapering of cone valve 3 is stuck on the air outlet 2, thereby cuts off the coal gas that enters gas ring.
