Abstract
The utility model relates to an automatic drain valve of a gas storage tank. The automatic drain valve of the gas storage tank comprises a valve body, a valve element, sealing rings, stainless steel springs, gaskets, fixing nuts, a drainage hole, and a lateral hole. The automatic drain valve of the gas storage tank is characterized in that pipe threads are arranged on the periphery of one end of the valve body, the other end of the valve body is in a hexagonal-nut shape, the valve element penetrates through the valve body and is fixed on the valve body, the diameter of the valve element gradually becomes larger from bottom to top, the sealing rings are arranged between one end of the valve element and the valve body, each sealing ring is made of silica gel which is water-proof and oil-proof, the fixing nuts are arranged at the other end of the valve element, the gaskets are arranged at the outer end of the valve element and on the inner side of the fixing nut, gaps are reserved between the valve element and the valve body, the stainless steel springs are arranged on the periphery of the valve element and are arranged in the gaps formed between the valve element and the valve body, the drainage hole is formed in the valve element, the lateral hole is formed in one side of the valve element, and the drainage hole is communicated with the lateral hole. The automatic drain valve of the gas storage tank has the advantages of being simple in structure, small in size, small in number of parts, easy to manufacture, convenient to use, capable of achieving automatic drainage, time-saving, and labor-saving.
Description
Technical field
The utility model relates to machinery industry, specifically a kind of gas holder automatic drain valve.
Background technique
Existing gas holder bottom discharges water with stop valve, the draining that needs are artificial regularly, regular, not only time-consuming but also require great effort, due to problems such as management, a lot of long-term unattended drainages of point that use, cause air quality to descend, water molecule content is high, impact spraying, quality of product and the air tool normal operation of spraying paint.
Summary of the invention
technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of gas holder automatic drain valve is provided, the technological scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises valve body, spool, seal ring, stainless steel spring, pad, set screw nut, weep hole, side opening, it is characterized in that being provided with pipe thread in an end periphery of valve body, the other end of valve body is arranged to hexagon nut shape, spool passes valve body and is fixed together with valve body, the diameter of spool increases from bottom to top gradually, be provided with a circle seal ring between one end of spool and valve body, seal ring is by water-fast, the silica gel of oil resistant is made, the other end of spool is provided with set screw nut, inboard at spool outer end set screw nut is provided with pad, there is the space between spool and valve body, be provided with stainless steel spring on the spool periphery, stainless steel spring is arranged on the gap of spool and valve body formation, also be provided with weep hole in spool, spool one side also is provided with side opening, weep hole communicates with side opening.
Working principle: the utility model drain valve mainly is comprised of valve body, spool, seal ring, stainless steel spring, pad, set screw nut, and valve body one end has pipe thread, is connected with gas holder, and the other end is arranged to hexagon nut shape, is convenient to install.When air compressor was started working, gas holder had pressure gradually, and the spool of drain valve is under pressure, and when pressure surpassed the elastic force of spring, spool moved press seal circle, drain shut valve.Air compressor work for a long time can make generation seeping phenomenon in gas holder.At this moment close air compressor and stop its work, the reduction that the air pressure of gas holder inside can be gradually.During lower than the elastic force of spring, spring backs down spool, makes drain valve be in open mode, discharges the water in gas holder, reaches self-draining purpose when pressure.
The beneficial effects of the utility model are, the utility model is simple in structure, and volume is little, and component are few, and are easy to manufacture, easy to usely can reach self-draining purpose, and are time saving and energy saving.
