High-pressure steel cylinder valve disassembly device

The invention provides a disassembling device for a high-pressure steel cylinder valve, which is mainly for how to stably clamp the gas valve when the high-pressure steel cylinder is disassembled, so that the air separation can be smoothly completed, and the gas valve of different specifications The designer can achieve the same needs of the same folder assembly.

According to the general high-pressure cylinders, in order to ensure the safety of the storage gas, it is necessary to regularly carry out its structural safety test to avoid accidents such as air leakage or gas explosion caused by the structural problems of the cylinders during filling, transportation, storage and use. Guarantee the safety of life and property.

In the structural safety inspection of the above-mentioned high-pressure steel cylinders, in order to facilitate the implementation of the inspection operation, the gas valve of the high-pressure cylinder must be removed and removed first, and after the inspection side is completed, the gas valve is reinstalled, and the high pressure is matched. The special operation of the cylinder valve dismantling operation is specially developed.

The high-pressure cylinder valve device of the prior art is mainly designed to have a sleeve holder that can be attached to a rotating machine. The sleeve holder is provided with a sleeve for the high-pressure cylinder valve to be used. The size of the sleeve is matched with the specification of the gas valve, so that the sleeve holder sleeve contains the high-pressure cylinder valve to form a proper clamping limit, and the clamp clamps the clamp of the high-pressure cylinder bottle body to make it start. When the machine is rotated, the valve holder can be rotated to remove the gas valve from the high-pressure cylinder to facilitate the inspection of the high-pressure cylinder.

However, the above-mentioned sleeve holder is only for the valve holding limit of the high-pressure cylinder. Purely using the combination of the size of the socket and the size of the valve, but considering the convenience of the valve and the clamping seat, the socket still needs to maintain a little clearance space with the valve, in order to smoothly complete it. The combination, in this way, the existence of the remaining gap space will naturally affect the stability of the nesting relationship, and even the loose colliding phenomenon occurs when the collet holder rotates with the rotating implement, which not only affects the stability of the valve disassembly operation, but also It is easy to cause damage to the structure of the valve or the clamping seat. In addition, the clamping seat can only be applied to the single-size air valve. For different specifications of the air valve, different sizes of the clamping seat may be required to meet the operation requirements. It is hard to call it the ideal designer.

In order to solve the problem of the looseness and collision of the above-mentioned single-clamping single-size specification, the manufacturer has changed the hydraulic-controlled clamp as the clamping and fixing of the high-pressure cylinder valve, so that it is more suitable for the valve assembly of the high-pressure cylinder. Stable, and can be applied to different specifications of the valve clamping position, obviously more practical, but because its overall structure is quite complex, relatively high equipment costs, and subsequent maintenance costs are not flawed, since it is not conducive to industrial utilization The economic benefits, it is necessary to try to solve the improvement.

In view of the fact that the conventional high-pressure cylinder valve disassembling device cannot be integrally applied to the disassembly of different specifications of the valve, and it is easy to collide in the valve insertion, removal and locking operation, resulting in structural damage, based on this, The inventor made a special effort to develop and develop a disassembling device that is easy to operate and can effectively clamp the fixed air valve, and at the same time, the single disassembling device is suitable for the valve clamping and disassembling of different specifications.

In order to achieve the universal applicability of the gas valve clamping of different specifications and the convenient operation of the clamping position, the present invention is a longitudinal long hole matching oblique axis which is engaged by the lower part of the seat body which is assembled by the rotating machine tool. The design of the clamping groove is such that a pivot rod is inserted in the longitudinal long hole to pivot Two pairs of rod-shaped rods arranged in a herringbone configuration are arranged, and then the corresponding connecting rods of the pair of connecting rod groups are respectively arranged with a clamping block which is arranged to slide on the wall of the inclined groove of the clamping groove, so that By means of the clips sliding on the wall of the inclined trough groove of the clamping groove to form different clamping sizes, the crucible can obtain a good clamping effect in response to the difference of the gas valve specifications of the high-pressure steel cylinder, so as to smoothly complete the valve disassembly of the high-pressure steel cylinder. Group operator.

The high-pressure cylinder valve disassembling device of the invention is designed not only to be suitable for clamping and positioning of gas valves of different specifications, but also to be more convenient and stable in the clamping operation of the gas valve. There is no problem of loose collision, which can effectively avoid structural damage, and its overall structure is simple, when it can better meet the economic benefits and practical value of industrial utilization.
