Abstract
The utility model relates to an easy-maintenance high-pressure pilot valve filter which comprises a filter body and a built-in filter core. The utility model is characterized in that: the filter body is composed of a seat and a housing; an upper end of the base is connected with the housing through threaded connection; the housing is axially provided with an air inlet and an air outlet; the air inlet is communicated with the inner chamber of the seat; and the air outlet is communicated with an upper end of the built-in filter core. The easy-maintenance high-pressure pilot valve filter obtains the following beneficial effects through adopting a screw thread sealing connection mode of the filter and equipping high-precision filter core in the seat: quick detachment and maintenance, quick cleaning to the impurities in the medium, protection normal using of the valve and the device. The phenomena such as pilot valve blocking of an emergency cut-off valve, pressure adjustment precision reduction of an operation pressure adjusting valve and function failure, which are caused by the impurity of natural gas in long-distance conveying pipe, are prevented. The easy-maintenance high-pressure pilot valve filter furthermore has the following advantages: low cost, simple process, effectively ensured normal operation of the emergency cut-off valve and the pressure adjusting valve, and ensured stable conveying of the long-distance conveying pipe.
Description
Technical field
The utility model belongs to filter, relates in particular to a kind of high pressure pilot valve filter of easy care.
Background technology
Filter is a midget plant of removing small amount of solid particle in the gas; can protect the operate as normal of equipment; after entering the filter cylinder that is equipped with the certain specification filter screen when gas; its impurity is blocked; and the gas of cleaning is flowed out by filter outlet; when needs clean, dismountable filter cylinder need be taken out, reload after the processing.It is strong that stainless steel filter has a pollution resistance, and blowdown is convenient, and circulation area is big, and the pressure loss is little, and is simple in structure, and volume is little, and is in light weight.Filter core material corrosion resistance is strong, and characteristics such as long service life, blowdown convenience are widely used in oil and gas industry.At present, filter is connected by the pressure samples pipe (pressure pipe) of the pilot valve (pilot valve) of safety cut-off valve in flange and the natural gas transmission station control pressurer system and pressure regulator valve, reaches the effect of filtering and sampling gaseous impurity.Because filter adopts flange connection, safeguard and clean difficulty; so appear in the gas course of conveying through regular meeting; the impurity of natural gas in long distance pipeline causes the pilot valve of quick action emergency valve to stop up, and work pressure regulator valve pressure regulation precision reduces, and causes its functional failure.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology; and provide a kind of high pressure pilot valve filter of easy care; filter adopts thread connecting mode and enclosure interior that the high accuracy filter core is installed; can reach fast assembling-disassembling and safeguard and remove the purpose of the impurity in the medium; normal use with protection valve and equipment; avoid the impurity of natural gas in long distance pipeline to cause the pilot valve of quick action emergency valve to stop up, work pressure regulator valve pressure regulation precision reduces, and causes the phenomenon of its functional failure to take place.
The utility model for achieving the above object, by the following technical solutions: a kind of high pressure pilot valve filter of easy care, comprise filter body and built-in filter core, it is characterized in that: described filter body is made of pedestal and housing, described pedestal upper end is threaded with housing, described housing is axially arranged with inlet, outlet, described air inlet and pedestal inner chamber UNICOM, gas outlet and built-in filter core upper end UNICOM.
The junction of described housing and pedestal upper end is provided with 0 sealing ring.
Beneficial effect: filter adopts that thread seal connected mode and pedestal are inner installs high-precision filter core, can reach fast assembling-disassembling and safeguard and remove impurity in the medium, with the purpose of the normal use of protection valve and equipment.Avoid the impurity of natural gas in long distance pipeline to cause the pilot valve of quick action emergency valve to stop up, work pressure regulator valve pressure regulation precision reduces, and causes the phenomenon of its functional failure to take place.Its cost is low, and technology is simple, has guaranteed the operate as normal of quick action emergency valve and pressure regulator valve effectively, ensures that the conveying of long distance pipeline is stable.

Among the figure: 1, safe emergency stop valve, 2, probe tube (pressure pipe), 3, pedestal, 4, housing, 4-1,4-2, inlet, outlet, 5, the O RunddichtringO, 6, filter core, 7, pilot valve (pilot valve), 8, monitoring pressure regulator valve, 9, the work pressure regulator valve, 10, filter.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides.See accompanying drawing for details, a kind of high pressure pilot valve filter of easy care, comprise filter 10 bodies and built-in filter core, described filter body is made of pedestal 3 and housing 4, and described pedestal upper end is threaded with housing, described housing is axially arranged with inlet, outlet 4-1,4-2, described air inlet and pedestal inner chamber UNICOM, gas outlet and built-in filter core upper end UNICOM, gas enters the pedestal inner chamber by air inlet, after passing through filter element filtering again, clean gas is discharged by the gas outlet.The junction of described housing and pedestal upper end is provided with 0 sealing ring 5.Pedestal and housing all adopt the 316L stainless steel (low temperature resistant, mechanical performance is excellent, high pressure resistant＞20Mpa), and the source of the gas on the pedestal connects (the preceding and back of filter) and all adopts 1/4 〞 F-NPT high pressure sealing to be threaded, housing and pedestal adopt the high pressure sealing screw thread of M20 * 1.5mm, and cooperate the sealing of BUNA-N rubber seal, reach the purpose of quick detachable, maintenance and blowdown; Enclosure interior is installed the filter core of high accuracy (0.5～5 μ), makes it have the advantages that volume is little, intensity is high, precision is high, impurity in the medium is safeguarded and removed to fast assembling-disassembling, has realized the normal purpose of using of protection valve and equipment.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
