Description
Technical field
This utility model relates to the high pressure filter using Split-type filter element structure of a kind of natural gas aerating machine, belongs to natural gas aerating machine valve technology field.
Background technology
The common configuration of the filter in existing natural gas aerating machine, generally comprise body, inlet chamber, outlet chamber, filter cartridge seat, drainage screen, filter screen skeleton, filter screen covers, bore seal circle, exterior seal ring, air inlet spiral shell, screw of giving vent to anger forms, wherein drainage screen, filter screen skeleton and filter screen capping are installed in filter cartridge seat, filter cartridge seat one end is loaded on body interior, carrier as parts such as drainage screens, other end is exposed outside body, coordinate Wrench, play assembling function, a bore seal circle it is provided with in the middle of filter cartridge seat, to isolate between inlet chamber and the outlet chamber of body interior；In actually used, because it is frequently necessary to unload filter cartridge seat, clean filter screen, bore seal circle is being manually loaded repeatedly, during taking on, can be collided with by metal parts, extrude and abrasion occurs, the frost that gases at high pressure impact and aerating pipeline occurs it is repeatedly subjected to because quick recharge causes local ambient temperature to be rapidly decreased to below zero degrees celsius when adding work, make sealing ring frequently by high/low-temperature impact, then bore seal circle there will be aging, deformation, abrasion, the phenomenon such as isolate, the result finally resulted in is exactly bore seal circle seal failure, filtering accuracy declines, and also frequently to change bore seal circle, the most damaged sealing ring fragment brings serious hidden danger of quality can to aerating equipment, add the maintenance cost of filling machine.
Summary of the invention
The purpose of this utility model is to provide the filling machine filter of a kind of Split-type filter element, can be used in high-pressure natural gas filling machine, on integrated filter core architecture basics, in outlet chamber position, filter element is divided into two, eliminate the soft sealing structure of bore seal circle simultaneously, top becomes a filter element lid, act the sealing function that leaks outside, bottom becomes a filter element spiral shell seat, it is connected with body inner hole thread, and with the body stepped hole bottom surface hard contact surface of stroke, both ensure that filtering accuracy, can stop again because filter element bore seal circle is aging, filtering accuracy that is damaged and that cause declines and other hidden danger of quality, this filtration device structure is novel in design, good stability, repeat dismounting ability strong, install more convenient, clean and maintenance easy maintenance, life-span is long.
For reaching above-mentioned purpose, this utility model specifically uses following scheme: the filling machine filter of a kind of Split-type filter element, including the body being provided with lumen orifice, it is placed in the air inlet screw bottom chamber body hole, it is placed in give vent to anger screw one and the screw two of giving vent to anger of both sides, chamber body hole, it is placed in the filter element lid that chamber body hole is suitable for reading, it is placed in the sealing ring between body and filter element lid, it is placed in the outlet chamber bottom filter element lid, it is placed in the ring-shaped drainage screen bottom filter element lid, it is placed in the filter screen skeleton inside drainage screen, it is placed in the filter screen capping bottom drainage screen, it is placed in outside drainage screen and inlet chamber between chamber body hole wall, it is characterized in that between the inlet chamber of body interior and outlet chamber, being provided with a filter element spiral shell seat；Described filter element spiral shell seat is completely disposed in body endoporus；Use between described filter element spiral shell seat and body and threaded；Described filter element spiral shell seat thread root plane is close to the baseplane, hole of body outlet chamber endoporus；Described filter element Luo Zuo center is provided with through hole, and the inlet chamber of described through hole connection body interior and outlet chamber, described through hole can be processed as inner hexagonal hole, it is simple to the installation of filter element spiral shell seat is tightened；Described filter element spiral shell seat is provided with filter element lid in outlet chamber side；It is provided with gap between described filter element lid and filter cartridge seat.
The filling machine filter of above-mentioned Split-type filter element, has an advantage in that:
1. filter quality improves.Described filter element spiral shell seat is not directed to rubber seal, the hidden danger of quality such as aging, damaged, fragment having stopped rubber seal, improves the filter quality of filter.
2. good stability, the life-span is long, and clean and maintenance is convenient.Owing to being no longer necessary to bore seal circle, filter element spiral shell seat after each wash, can easily load body, it is to avoid because sealing ring aging, damaged or install not in place and hidden danger of quality occur, has fully ensured that the convenience safeguarded；And can prolonged and repeated dismount, the life-span is long.
3. parts machining process is simple, reduces metalwork burr.Existing integrated filter core outlet chamber and giving vent to anger needs between screw to process multiple sides through hole and one big passage of filter element center processing, and hole is more, easily produces burr；Described Split-type filter element, outlet chamber and give vent to anger and be provided with enough airspaces between screw, intercept without other parts, only need filter element Luo Zuo center to process a through hole, it is to avoid do not remove the hidden danger that burr brings.
