Abstract
The utility model discloses a liquid gas steel cylinder valve which comprises a valve body, a valve plate, a valve head and valve rods, wherein a keyway is arranged between the positions of the valve rods and a pin which is inserted on the valve body is arranged on the position of the keyway. The upper parts of the valve rods which are combined with hand wheels are also provided with stop rings. Because a copper pin is fixedly riveted in the liquid gas steel cylinder valve, the liquid gas steel cylinder valve can not be disassembled. The top and bottom of the valve head is in a rectilinear path, the lifetime of the valve is increased and the life test can be increased from the original 8000 times to the present 30000 times. A turning part arranged at the upper part of the liquid gas steel cylinder valve is increased with a dust-proof device, and no dust can be embedded in screw thread positions. Thus, the cleanness of the valve rod can be kept, the dust prevention effect of the valve can be enhanced, the use effect can be ensured, the beauty is added and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of cylinder for liquefied gas valve.
Background technique
Cylinder for liquefied gas valve originally is detachable; because the steel cylinder inspection point needs often to exchange the interior fittings of cylinder valve; but they are not professional production producers; often all lack relevant detection equipment; and the enterprise that valve fittings is provided is careless about quality of product; therefore changing the designing requirement that does not reach former valve after the interior fittings, caused security incident to stay hidden danger.In addition, because outside the valve rod top of valve is exposed to all the time, the long-term use has dust and embeds the screw thread position, thereby influences the using effect and the working life of valve.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of non-dismountable, increase the cylinder for liquefied gas valve of life of valve and safety in utilization greatly.
In order to achieve the above object, a kind of cylinder for liquefied gas valve that the utility model is designed, it comprises valve body, valve block, valve head and valve rod, the position is provided with cotter way between the bar of valve rod, is provided with the pin that inserts from valve body in the cotter way position.In order to prevent that dust from embedding the screw thread position, the position that combines with handwheel on the top of valve rod also is provided with ring washer.
Cotter way can be located at the structure intermediate portion of valve rod, pin can adopt two, and the both sides that are located at valve rod can rotate the valve rod that has cotter way portion through cotter way in the pin gap, the pin available copper is made, and the rotation of valve rod drives the upper and lower mobile keying effect of playing of valve head.The ring washer available copper is made, and during design, the outer warp of ring washer just shelves is lived valve body top, and the height of ring washer can just be the distance that valve rod moves up and down.
The resulting a kind of cylinder for liquefied gas valve of the utility model, because the copper pin fixedly rivets, it is non-dismountable to reach the cylinder for liquefied gas valve, because valve head moves up and down, so can increase life of valve greatly, can be increased to present 30,000 times from original 8000 times according to the test life test.
Rotate on cylinder for liquefied gas valve top partly increases dust guard.Ring washer made of copper has covered the position of valve rod upper exposed all the time in the using process of cylinder valve like this, just do not have dust and embed the screw thread position, thereby the cleaning that has kept valve rod, the dustproof effect of raising valve guarantees using effect, has increased working life attractive in appearance and the prolongation valve.After having increased a copper ring washer, played the effect that coordinate at the position also for whole valve.

Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, a kind of cylinder for liquefied gas valve that present embodiment is described, it comprises valve body 1, valve block 2, valve head 3 and valve rod 5, the position is provided with cotter way between the bar of valve rod 5, is provided with the pin 6 that inserts from valve body 1 in the cotter way position.Cotter way can be located at the structure intermediate portion of valve rod 5, and pin 6 can adopt two, and the both sides that are located at valve rod 5 are through cotter way, the valve rod 5 that has cotter way portion can be rotated in the pin gap, the pin available copper is made, and the rotation of valve rod drives valve head 3 and moves up and down, and plays the keying effect.As shown in Figure 2, the position that combines with handwheel 7 on the top of valve rod 5 also is provided with ring washer 10, and the ring washer available copper is made, and during design, the outer warp of ring washer 10 just shelves is lived valve body 1 top, and the height of ring washer 10 can just be the distance that valve rod 5 moves up and down.
