Special device for gas cylinder drainage

Abstract

The invention relates to a device special for gas bottle water draining. The device is characterized by comprising a connecting rod and a guide sleeve; the guide sleeve is in sealed connection to the connecting rod and comprises a guide part and a connector part, a shaft shoulder is arranged at the connecting position of the guide part and the connector part, and a sealing ring is arranged on the shaft shoulder; an inner cavity is formed in the connecting rod, an inner cavity ventilation hole communicated with the connecting rod is formed in the guide sleeve, and an air outlet hole is formed in the connector part of the guide sleeve; an inner thread is arranged in the middle of the inner cavity of the connecting rod, a core rod is coaxially arranged in a ventilation hole of the guide sleeve, and the inner thread in the inner cavity of the connecting rod is in threaded connection to the upper end of the core rod; a telescopic rod is sleeved with the lower end of the core rod in a sliding manner, a kidney-shaped hole is formed in the telescopic rod, and a pin shaft arranged on the core rod in a radial manner penetrates the kidney-shaped hole; a copper nut is arranged at the lower end of the telescopic rod, and a radial groove is formed in the bottom face of the copper nut; and the device is simple and compact in structure, convenient to operate and low in manufacturing cost, water in a gas bottle can be rapidly drained, the water draining efficiency is improved, and automation of gas bottle water draining is achieved.

Description

technical field [0001] The invention relates to a drainage device, in particular to a special device for drainage of gas cylinders. Background technique [0002] After the pressure gas cylinder or airtight cylinder is subjected to hydrostatic testing or cleaning, the water in the cylinder needs to be poured out and dried before use. At present, the pouring of gas cylinders mainly depends on the manual operation of the operator, or hoisting the gas cylinders to the auxiliary equipment for flipping and pouring water, turning over and pouring out the water in the gas cylinders, relying on the natural flow of water to drain water slowly, with low drainage efficiency and It is not conducive to the recycling and reuse of water, and the labor intensity of the operators is high. In addition, the auxiliary equipment for turning over and pouring water has a complicated structure and high manufacturing cost, and it is difficult to realize automatic operation.
