Description
Technical field
The utility model belongs to the filter plant field, particularly a kind of filter flask that is fitted to filter be used to the filter core of packing into.
Background technology
Filter flask is a kind of filter plant be used to the filter core of packing into, market upper filter kind is very many, filter core comprises PP filter core, UDF filter core and CTO filter core etc., can be according to filter to require selecting the different filter cores filter flask of packing into, and filter flask is packed into and is just formed complete filter behind the filter core.Existing filter flask mainly is comprised of filter flask body and filter cover, filter core is installed in filter flask body the inside, and for the ease of installing and changing different filter cores, existing filter flask assembly all has eaily detaching structure, be that filter flask body and filter cover generally are by common screw connection structure, turn on conveniently.But, filter flask accessed water circuit system after, because the filtration resistance of filter core can make the intrinsic hydraulic pressure height of filter flask and air pressure large, existing this filter flask adopts common screw connection structure, the bonding strength of regular screw threads is inadequate, and bearing capacity is poor, and under high pressure screw thread can be very tight, turn on the screw thread dismounting is not easy very much, structure is very unreasonable, and this class filter flask junction poor sealing, after long-term the use, the problem such as occur leaking in the junction easily, service life is short.
For above-mentioned subproblem, some filter flask is provided with steam vent in filter cover, but the air bleeding valve on the steam vent all is to cooperate some seal members directly to shut with screw or bolt, with screwdriver screw or bolt are back-outed during release, worse, the screw on water filtration device or bolt are as easy as rolling off a log to get rusty, and can't back-out, therefore existing this air bleeding valve unreasonable structure is still laid down the filter flask internal gas pressure and is bothered very much.
Summary of the invention
Goal of the invention of the present utility model provides a kind of rational in infrastructure, and it is quick and convenient to lay down the filter flask internal gas pressure, dismounting and more renew cartridge is convenient, and its filter flask body and filter cover junction bearing capacity are strong, the filter flask of good leak-proof effect.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
A kind of filter flask comprises that filter cover top is provided with water inlet, delivery port and steam vent for filter flask body, filter cover, air bleeding valve, leakproof seal circle that filter core is installed, and air bleeding valve is installed in the steam vent place; Described air bleeding valve comprises bolt, exhausting seal ring, spring and nut, and the head of bolt is in the filter cover inboard, and the spiro rod section of bolt passes steam vent and extends the filter cover outside; Exhausting seal ring is in the filter cover inboard, and exhausting seal ring is enclosed within on the bolt and is between the head and steam vent of bolt; Spring and nut are in the filter cover outside, and nut is connected to the end of spiro rod section, and spring housing is on the spiro rod section and be between steam vent and the nut; Described filter cover bottom is connected rectangular thread with filter flask body top and is connected, and the leakproof seal circle is between filter cover and the filter flask body.
As preferably, described filter cover bottom is provided with the lid mouth with the filter flask Ontology Matching, and a lid mouthful lateral wall is provided with outer rectangular thread; The madial wall on filter flask body top is provided with interior rectangular thread, and the sidewall of interior rectangular thread below is provided with annular erecting bed; Leakproof seal circle bottom is installed on the annular erecting bed, and top is against on the oral area end face of lid mouth.
Adopt the designed filter flask of such scheme, at first, the filter cover bottom is connected rectangular thread with filter flask body top and is connected, and the bonding strength of rectangular thread is high, and bearing capacity is large, satisfies general filtration resistance and produces to get pressure.In addition, the O RunddichtringO is between filter cover and the filter flask body, cooperates with rectangular thread, and is rational in infrastructure, and having overcome rectangular thread, to compare general precision not high, and the deficiency of sealed against leakage is so that the junction good sealing effect prevents from leaking long service life.Moreover filter cover top also is provided with steam vent and is installed in the air bleeding valve at steam vent place, and this exhaust structure is new reasonable, compares the air bleeding valve on the existing filter flask, need only press lower nut and can realize the exhaust release, and is simple to operate.When renew cartridge more, can conveniently turn on screw thread at an easy rate with the air pressure emptying in the filter flask, renew cartridge is convenient easily and more in dismounting.In a word, the major advantage of this filter flask is: novel structure and reasonable, and the pressure operation that sheds in the filter flask is convenient, and renew cartridge is convenient easily and more in dismounting, the good sealing effect of junction when filter flask body and filter cover bonding strength height, bearing capacity Datong District, thereby long service life.

The specific embodiment
The below is described in further detail the technical solution of the utility model by reference to the accompanying drawings.
A kind of filter flask comprises for filter flask body 1, filter cover 2, air bleeding valve 5, leakproof seal circle 3 that filter core is installed as shown in Figure 1.
Air bleeding valve 5 comprises bolt 53, exhausting seal ring 54, spring 52 and nut 51.The head 53a of bolt is in filter cover 2 inboards, and the spiro rod section 53b of bolt 53 passes steam vent 23 and extends filter cover 2 outsides.In filter cover 2 inboards, exhausting seal ring 54 is in filter cover 2 inboards, exhausting seal ring 54 is enclosed within on the bolt 53 and is between the head 53a and steam vent 23 of bolt, be that exhausting seal ring 54 top elasticity are pressed on filter cover 2 madial walls at place, steam vent 23 inside edges, bottom elasticity is pressed on the head 53a of bolt.In filter cover 2 outsides, spring 52 and nut 51 are in filter cover 2 outsides, nut 52 is connected to the end of spiro rod section 53b, spring 52 is enclosed within spiro rod section 53b upward and is between steam vent 23 and the nut 52, be that spring 52 upper ends are pressed in nut 52 bottoms, the lower end is pressed on filter cover 2 lateral walls at steam vent 23 outer ledge places, and the tension force of spring 52 transmits so that the head 53a of above-mentioned bolt and exhausting seal ring 54 are airtight with steam vent by bolt 53.As long as press lower nut 52, Compress Spring sheds its tension force just so that the head 53a of bolt and exhausting seal ring 54 leave filter cover 2 madial walls, and gas is emitted, and operates very simple.
Is connected top and connects by rectangular thread in above-mentioned filter cover 2 bottoms with the filter flask body, the leakproof seal circle is between filter cover and the filter flask body.Specifically filter cover 2 bottoms are provided with the lid mouth 24 that mates with filter flask body 1, and lid mouthful 24 lateral walls are provided with outer rectangular thread 241.The madial wall on filter flask body 1 top is provided with interior rectangular thread 11, and the sidewall of interior rectangular thread 11 belows is provided with annular erecting bed 12.Leakproof seal circle 3 bottoms are installed on the annular erecting bed 12, and top is against on the oral area end face of lid mouth 24.
During use, water inlet 21 and delivery port 22 are connected respectively oral siphon and outlet pipe, filter when needing more renew cartridge after a period of time, turn on first the nut 51 of pressing on the lower air bleeding valve 5, pressure in the emptying filter flask, then rotating filter flask body 1 can separate filter flask body 1 again with filter cover 2, more renew cartridge is very convenient.
