Abstract
The utility model provides a combination integrated filter check valve, and relates to a fluid pipeline valve device. The combination integrated filter check valve comprises a vertical cylinder type strainer filter and a valve core lifting type check valve. The filter comprises a cylinder body, a cylinder cavity, a cylinder type strainer, a water inlet elbow, a water inlet, a water outlet and a drain outlet. The valve core lifting type check valve comprises a valve body, a valve cavity, a valve carrier, a valve core, a valve rod, a valve rod guide cavity, a valve cover, a water outlet and a water inlet. The vertical cylinder type strainer filter and the valve core lifting type check valve are integrated side by side, and the water outlet 19 on one side of the lower portion of the vertical cylinder type strainer filter is connected with the water inlet 20 at the bottom of the valve core lifting type check valve through the elbow 11 having the 90-degree radian. The valve core is made of Teflon, copper powder, graphite, corundum powder and silicate adhesives in a mixing, blank making and high-temperature sintering mode. The combination integrated filter check valve has the advantages that an existing check valve and an existing filter separated from the exiting check valve are improved and combined into a whole, dual functions of filtering and checking are achieved, production and installation cost is lowered, pipeline equipment is simplified, installing, maintaining and using convenience is achieved, and the effect is good.
Description
Technical field:
The utility model relates to fluid filter and valve, relates generally to combined integrated filtering flow safety check.
Background technique:
Fluid piping system, particularly steam condensing reclaim line system, condensing reclaims compressor water intake and is connected to safety check, and safety check water inlet needs connect gas utilization unit through filter, take to guarantee that condensing reclaims compressor safe operation and be boiler feed water, guarantees feed-water quality.Existing safety check is all separated single equipments with filter, on pipeline, its serial connection is installed and used, and the expense that this had both increased the auxiliaries such as pipeline, flange, sealing gasket, has increased again the trouble inconvenience of installation and maintenance.Moreover the existing safety check life-span is short, noise is large.
Summary of the invention:
The object of the utility model, is to provide a kind of unitized filter check valve, has and filters and non-return dual functions.Easy to use, save and produce and installation cost.Safety check long service life, noise are little.
Embodiment of the present utility model is that a kind of unitized filter check valve, comprises filter, safety check.Described filter comprises cylindrical shell 12, cylinder chamber 13, cartridge type filter screen 14, water intake 16, water outlet 19, sewage draining exit 18.Described safety check comprise valve body 1, valve pocket 2, valve seat 3, spool 4, with valve rod 5, stem guiding chamber 6, water outlet 10, the water intake 20 of spool one.Feature is, described filter is vertical barrel filter, and dismountable water inlet elbow 15 is established at cylindrical shell top, and water inlet elbow upper end is water intake 16, and cylindrical shell bottom one side sets out the mouth of a river 19.Described safety check is spool Lift check valve, and dismountable valve gap 7 is established at valve body top, and valve body lower portion one side sets out the mouth of a river 10.Vertical barrel filter and spool Lift check valve are combined integrated side by side, and the water outlet 19 of vertical barrel filter bottom one side is the water intake 20 of the bend pipe 11 connection valve core lift type safety check bottoms of 90 ° by radian.
Further preferably, the spool 4 of described spool Lift check valve is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing to the utility model embodiment, through mixing, embryo processed, high temperature sintering, makes.
Good effect of the present utility model:
The utility model is improved the safety check of existing separation and filter respectively and combines is made as one, has and filters and non-return dual functions, has reduced production and installation cost, has simplified pipeline equipment, installation and maintenance, convenient application, and using effect is good.High abrasion resisting material spool long service life, noise is little.
accompanying drawing explanation:
Accompanying drawing 1 the utility model sectional view
Reference character: 1, valve body 2, valve pocket 3, valve seat 4, spool 5, valve rod 6, directed cavity 7, valve gap 8, sealing gasket 9, bolt 10, water outlet 11, bend pipe 12, cylindrical shell 13, cylinder chamber 14, filter screen 15, elbow 16, water intake 17, bolt with one end bent back 18 sewage draining exits.
Embodiment:
Accompanying drawing 1 has provided a kind of embodiment of the present utility model.Unitized filter check valve, comprises filter, safety check.
Described filter is vertical barrel filter, comprise cylindrical shell 12, cylinder chamber 13, cartridge type filter screen 14, water outlet 19, sewage draining exit 18, cylindrical shell top is provided with dismountable water inlet elbow 15 by bolt with one end bent back 17, and elbow upper end is water intake 16, and cylindrical shell bottom one side sets out the mouth of a river 19.
Described safety check is spool Lift check valve, comprise valve body 1, valve pocket 2, valve seat 3, spool 4, with valve rod 5, stem guiding chamber 6, the valve body water outlet 10 of spool one, valve body top is provided with detachable valve gap 7 by bolt 9 and sealing gasket 8, and valve body lower portion one side sets out the mouth of a river 19.
Vertical barrel filter and spool Lift check valve are combined integrated side by side, and the water outlet 19 of vertical barrel filter bottom one side is the water intake 20 of the bend pipe 11 connection valve core lift type safety check bottoms of 90 ° by radian.The valve body of the cylindrical shell of vertical barrel filter and spool Lift check valve is casting integrated.
Working procedure, water intake connects watering equipment return pipe, and water outlet connects condensing and reclaims compressor compresses cylinder water intake.Filter sewage draining exit 18 is installed sewage draining valve.Watering equipment water out first enters filter through water intake 16 through water inlet elbow, after strainer filtering, by water outlet 19, discharged, through bend pipe 11, safety check water intake 20, back down spool 4 again and enter valve pocket 2, and enter condensing recovery compressor compresses cylinder by water outlet 10, give boiler replenishing water.
The spool 4 of the utility model spool Lift check valve, is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing, through mixing, embryo processed, high temperature sintering, makes, and has high wear resistance, long service life.
