Abstract
The utility model relates to a liquefied petroleum gas cylinder valve which comprises a valve body, a movable gate, a connecting plate, a valve rod, a valve cap, an upper sealing gasket, a sealing gasket, a hand wheel, a potential coil and a nut as the original liquefied petroleum gas cylinder valve. The lower half part of the valve body of the original cylinder valve is provided with an internal conic hole rather than a straight through hole. The internal conic hole has equal wall thickness with the distance between the external screw threads on the surface of the valve body. A lower sealing gasket is additionally arranged on the lower end of the upper sealing gasket. The valve body of the improved cylinder valve can save a certain quantity of copper material, and the service life of the product is extended. The liquefied petroleum gas cylinder valve is a product of large quantity demand and broad application. Having large batch production, the utility model can save a nonnegligible quantity of copper materials for the nation, because the utility model does not change the size and can be matched with the original steel cylinder.
Description
The utility model relates to a kind of cylinder valve liquefied petroleum gas cylinder valve.
Along with improving constantly of people's living standard, increasing user has used liquefied petroleum gas (LPG), thereby the demand of liquefied petroleum ga steel cylinder also grows with each passing day, the wide product of this cylinder valve amount of being multiaspect, if can save some materials on each cylinder valve, the material under the annual saving in the whole nation is exactly the considerable and numeral that can not ignore.
The patent No. 89207232.6 " LP gas cylinder valve " has just solved the gas leak phenomenon of angle valve.
The purpose of this utility model is to provide a kind of liquefied petroleum gas cylinder valve, is improved on original cylinder valve basis, changes the valve body shape, saves the consumption of valve body material, thereby reaches the purpose that reduces cost.
The utility model is achieved in that this cylinder valve is the same with original cylinder valve, is made up of valve body, valve, web, valve rod, bonnet, last sealing gasket, sealing gasket, handwheel, packing ring, nut.Change lower half portion of original valve body lower end clear opening into internal taper hole, and make between inner cone hole wall and valve body surface outside thread for etc. wall thickness, and set up sealing gasket in last sealing gasket lower end.
Accompanying drawing, structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Three through holes are arranged in the former valve body, now lower half portion of a clear opening of valve body (1) lower end is had instead the internal taper hole of tapering, tapering is 3～5 °, and make between taper hole inwall and valve body surface outside thread for etc. wall thickness, and valve body external shape size constancy makes it and the supporting use of former steel cylinder energy.
Between former bonnet (5) and valve body (1) last sealing gasket (7) is arranged, now increase a lower seal pad (6) of being made by teflon or nylon again, the wear resistance of sealing gasket in the raising (7) increases its working life, and it is light that handwheel (9) is rotated.
Other structure is the same with former cylinder valve, with nut (11), pad (10) handwheel (9) is fixed on the valve rod (4), web (3) connects to one with valve rod (4), valve (2), valve body (1) top pad is gone up upper and lower sealing gasket (7), (6) connect to one with bonnet (5), is lined with sealing gasket (8) between bonnet (5) and valve rod (4).
Concrete working procedure is the same with original cylinder valve, and clockwise direction rotates handwheel (9), and drive valve (2) by valve rod (4), web (3) and rotate the sealed mouth that compresses valve body (1) downwards, thereby with valve closing.Otherwise, can open valve.
Because of the clear opening with valve body (1) lower end is modified into internal taper hole, change valve body (1) shape, the copper consumption of valve body (1) is reduced, promptly every cylinder valve has been saved many copper materials, has reduced cost.Because of the lots of production of each producer is all very big, therefore the nervous material of saving for country also is considerable.The liquefied petroleum gas cylinder valve of this structure also can be used on the industrial big liquefied petroleum ga steel cylinder except that being used in household liquified gas cylinder.
Claims (2)
1, a kind of valve liquefied petroleum gas cylinder valve, with pad (10), nut (11) handwheel (9) is fixed on the valve rod (4), web (3) connects to one with valve (2), valve rod (4), valve body (1) top pad is gone up sealing gasket (7) and is connected to one with bonnet (5), be lined with sealing gasket (8) between valve rod (4) and bonnet (5), it is characterized in that the Lower Half of valve body (1) lower end clear opening is an internal taper hole.
2, cylinder valve according to claim 1, it is characterized in that between valve body (1) lower end inner cone hole wall and the surperficial outside thread of valve body (1) for etc. wall thickness, the internal taper hole tapering is 3～5 °, and last sealing gasket (7) also has down a lower seal pad (6) of being made by teflon or nylon.
