A pressurized tank for filling

Abstract

The invention discloses a pressurized tank for filling. Its structure includes: a sub-packaging body, a filling conversion device, a communication pipe, an air outlet valve, a pressure valve device, an air inlet, a main tank body, and a bearing seat, so that the equipment can be used At the same time, through the self-regulating mechanism provided, the present invention can avoid the filling work of the pressurized tank in the filling head. The existing filling head needs to rely on the pressure gauge for auxiliary assistance. When there is a power failure or pressure When the meter breaks down, the filling head may exceed the load pressure, which has certain disadvantages and safety hazards in terms of operability, so that the equipment cooperates with the safety buckle device, and the filling supervisor is always in a position. Transfer in the safe pressure range, which has the function of double-layer insurance. At the same time, through the cooperation of the split air bag device and the shunt tube, the pressure at the end of the split tube is assisted and self-adjusted, effectively ensuring that the tube pressure at the rear of the filling is maintained at A reasonable range will indirectly increase the service life of the equipment.

Description

technical field [0001] The invention relates to a pressurized tank for filling, belonging to the field of pressurized tank equipment. Background technique [0002] For many industries, the pressurized tank has become a familiar item, and its functions have become more comprehensive and developed in a better direction with the development of the production period. The most important thing is that it can pass the internal To achieve the balance of stored water, prevent the pressure formed between opening and closing, and better preserve and transport filling materials. [0003] The existing technology has the following shortcomings: in the sub-packaging work of the filling head of the pressurized tank, the existing filling head needs to rely on the pressure gauge for auxiliary assistance. When there is a power failure or the pressure gauge fails, the filling head may There will be a situation where the load pressure is exceeded, resulting in dangerous situations such as burst...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a pressurized tank for filling, so as to solve the problem that the filling head of the existing pressurized tank needs to rely on the pressure gauge during the subpackaging work of the filling head. With auxiliary assistance, when there is a power failure or a pressure gauge fails, the filling head may exceed the load pressure, resulting in dangerous situations such as the bursting of the filling head, which has certain disadvantages and safety hazards in terms of operability. question
