Description
Technical field:
The utility model relates to a kind of fuel gas pipeline cut-off valve.Especially relate to a kind of pneumatic cut-off valve that is applicable to coke oven crude gas.
Background technique:
The cut-off valve of institute's adapted has multiplely on the existing fuel gas pipeline, is used for directly and burner is complementary and will realize that the fuel gas shutoff valve of controlling automatically is mainly the electromagnetic type cut-off valve.But for coke oven crude gas, electromagnetic shut-off valve just can not adapt to, and tracing it to its cause is that the structure and the kind of drive by this valve determined.The unlatching of electromagnetic shut-off valve picks up magnet drive valve rod by electromagnetic force and spool is lifted off a seat the mating face and realized that closing is to reply by spring force.The main activities part spool of this valve, valve rod, spring, Sealing valve seat all are common ferrous material, this valve is in running, and above-mentioned parts all contacts with coke oven crude gas, owing in the coke oven crude gas a large amount of aggressive mediums is arranged, so these parts all are unable to undergo corrosion; Secondly, because goo tar and crystalline solid naphthalene in the coke oven crude gas adhere on the movable members, make the regular event of part be obstructed, in this case, the electromagnetic force that just seems deficiency can not guarantee the coke oven crude gas sealing of low-pressure.Influencing solenoid valve normally uses; In addition, the spool of this valve and valve seat are rigid face contact seal, if be stained with dirt on spool or the valve seat, just cause seal failure, make gas leakage; Moreover this valve body bottom does not have and establishes drainage device, if can't discharge when sludge or raffinate are arranged, may directly cause fault in the valve.In sum, the electromagnetic type cut-off valve can not adapt to the coke oven crude gas use.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of pneumatic cut-off valve that is specially adapted for coke oven crude gas is provided, with the switching strength, breakdown action and the sealing reliability that improve valve and in time sludge or raffinate in the expulsion valve.
The purpose of this utility model is achieved in that a kind of pneumatic cut-off valve that is applicable to coke oven crude gas, be characterized in that it comprises valve body, coal gas advances, outlet, valve seat, spool, valve rod, valve gap, air bag, pallet, cluster spring, the gasbag chamber loam cake, the gasbag chamber lower cover, support, combination and sewage draining exit, coal gas advances, outlet is arranged at the valve body both sides, the valve body upper end links to each other with combination, combination links to each other with valve gap, valve gap links to each other with support, support links to each other with the gasbag chamber lower cover, the gasbag chamber lower cover links to each other with the gasbag chamber loam cake, on the gasbag chamber, form gas between the lower cover and assist the chamber, air bag places in the gasbag chamber, pallet places on the air bag upper-end surface, the valve rod lower end links to each other with spool, spool places on the interior valve seat of valve body, and combination is passed in the valve rod upper end, valve gap and support link to each other with air bag with pallet in placing gasbag chamber, and cluster spring places on the pallet, gasbag chamber lower cover one side is offered compressed air inlet, and sewage draining exit is opened in the valve body bottom.
The utility model also can be equipped with bellows or spring on the valve rod in combination, to improve the switching strength of valve, accelerates the sealing reliability of the closing motion and the raising valve of valve.
The utility model provides a kind of cut-off valve that aims at coke oven crude gas, and it is the actuator of power that this valve adopts pressurized air, the big and flexibility and reliability of valve valve opening force amount.The valve rod and the spool of this valve are manufactured with stainless steel material, and valve body is cylinder iron manufactured, and valve seat is manufactured with teflon, has solved etching problem; Teflon has good toughness, and is that line contacts with spool, so good airproof performance can not make in the coal gas and let out; The valve bottom blowdown is convenient again, so this valve adapts to the coke oven crude gas use fully.
Fig. 1 is the structural representation of this model utility.This valve is made up of valve body 1, coal gas inlet/outlet 20,2, valve seat 3, spool 4, valve rod 6, valve gap 7, air bag 8, pallet 9, cluster spring 10, gasbag chamber loam cake 12, gasbag chamber lower cover 15, support 16, elastic bellows or spring 17, combination 18, sewage draining exit 21 and attachment bolt 13, diaphragm of rubber 5 etc. among the figure.Coal gas advances, outlet 20,2 are arranged at valve body 1 both sides, valve body 1 upper end and combination 18 adopt the bolt connection to connect, diaphragm of rubber 5 sealings are set between valve body 1 and the combination 18,7 of combination 18 and valve gaps adopt the bolt connection to connect, valve gap 7 links to each other with support 16, support 16 links to each other with gasbag chamber lower cover 15, gasbag chamber lower cover 15 links to each other with gasbag chamber loam cake 12, on the gasbag chamber, lower cover 12, form gasbag chamber 11 between 15, air bag 8 places in the gasbag chamber 11, on gasbag chamber, lower cover 12,15 are fixedly connected by bolt 13, and pallet 9 places on air bag 8 upper-end surfaces, and valve rod 6 lower ends link to each other with spool 4, spool 4 places on the valve seat 3 in the valve body 1, combination 18 is passed in valve rod 6 upper ends, valve gap 7 and support 16 link to each other with air bag 8 centers with pallet 9 in the gasbag chamber 11, and cluster spring 10 lower ends place on the pallet 9, and the upper end contacts with gasbag chamber loam cake 12.Gasbag chamber lower cover 15 1 sides are offered compressed air inlet 14.Bellows or spring 17 are placed on the interior valve rod 6 of combination, and sewage draining exit 21 is opened in valve body 1 bottom.
The working principle of this valve is such: pressurized air enters after the gasbag chamber bottom from gasbag chamber lower cover one side, under its pressure effect, move on air bag and the pallet, cluster spring and elastic bellows or spring are compressed simultaneously, valve rod and spool also with on move, spool is just lifted off a seat, this opening of valves, and coal gas passes through; When this valve cuts out, elder generation's closes compression air, under the double action of cluster spring power and elastic bellows or spring restoring force, accelerate closing motion, air bag and pallet reset, and pressurized air is extruded discharge in the gasbag chamber, simultaneously, valve rod and spool move down, and spool compresses valve seat and closes this valve, cuts off coal gas.Sealing is reliable.When the valve prodelta clay has sludge and raffinate, then can open sewage draining exit and in time discharge.
