Description

Partition-type full-automatic exhaust valve

Technical field

The utility model relates to a kind of automatic exhaust device, especially this device that is used for hot-water heating system and fluid pipeline system and has adopted gas barrier technology and ring densification to close technology.

Background technique

In hot-water heating system and fluid pipeline system, ducted air must be got rid of, just system's proper functioning can be made, to reach technical requirements.For this reason, be mostly to settle automatic control pressure vent at the lofty perch place of system, its structural type adopts link rod structure mostly, and wherein the major function part all is immersed in the water, easily gets rusty, and the work of structure action piece is reliable inadequately.Adopt isolated automatic vent needle-valve now in addition, with respect to the former bigger improvement has been arranged, but in long-term use, also there is the gap float tolerance deficiency between guide way and the guide pillar, unobstructed inadequately and owing to adopt the stylus structure causative action spare problem such as undesired of working sometimes, for example ball float up after, needs block when descending and do not fall after rise, again in order to play airtight effect reliably, must improve the processing grade of part, thereby increased cost etc., these aspects are all suddenly waited to improve, and design the outlet valve of the new structure form that overcomes above-mentioned shortcoming.

Summary of the invention

The utility model provides one to adopt the gas separating technology according to above-mentioned, increases air displacement, and the axial and horizontal surface friction drag between part of taking in sail makes its action smooth and easy, and employing encircles the densification technology of closing and makes the more reliable partition-type full-automatic exhaust of airtight process valve.

The utility model is realized by the following technical solutions.Partition-type full-automatic exhaust valve is mainly by valve body (1), guide way (2), air exhaust loop (3), outlet pipe (4), ball float (5), guide pillar (6) is formed, wherein, valve body (1) inner chamber top forms gas and cuts off chamber (11), and guide way (2) is loaded on gas and cuts off on the chamber (11), is shaped on air exhaust loop (3) in the guide way (2), outlet pipe (4) is housed on it, sealing gasket (62) is equipped with in guide pillar (6) end, and guide pillar (6) is fixed together with ball float (5), as movable part.

When ball float (5) floats to limit position, the sealing gasket of guide pillar (6) end compresses with air exhaust loop (3) and contacts, produce ring means of press seals effect, the gas that cuts off in the chamber is retained in body cavity top all the time, thereby reach the purpose of gas barrier, make liquid medium can not flow to guide way (2) and guide pillar members such as (6),, thereby increased air displacement and reduced surface friction drag because the section shape of guide pillar body (61) is a regular hexagon.

The utlity model has the gas-liquid cutting function, main function components is not contacted with liquid, can make member working properly, not perishable, be difficult for aging; In addition, adopted ring means of press seals technology, made sealing reliable, Sealing is not fragile, and part processing and assembly technology are simple, can reduce manufacture cost; Again because guide pillar body section is a hexagon, thereby has increased air displacement and reduced surface friction drag with guide way, member is moved up and down freely.

Description of drawings

Fig. 2 is the utility model general structure and ball float lifting position schematic representation

Among the figure: the 1-valve body, 11-gas cuts off chamber, 12-valve body flange, 13-seal ring, 14-bolt, the external mouth of pipe of 15-, 2-guide way, 3-air exhaust loop, 4-outlet pipe, 5-ball float, 6-guide pillar, 61-guide pillar body, 62-sealing gasket

Embodiment

As shown in Figure 1, structure of the present utility model is mainly by valve body 1, guide way 2, air exhaust loop 3, outlet pipe 4, ball float 5, guide pillar 6 is formed, and wherein, valve body 1 inner chamber top forms gas and cuts off chamber 11, guide way 2 is loaded on gas and cuts off on the chamber 11, be shaped on air exhaust loop 3 in the guide way 2, outlet pipe 4 is housed on it, sealing gasket 62 is equipped with in guide pillar 6 ends, guide pillar 6 is fixed together with ball float 5, as movable part.

As seen from the figure, valve body 1 has two-part up and down, the centre accompanies seal ring, fixing with bolt 14 through valve body flange 12 along valve body flange periphery, when hot-water heating system or fluid pipeline system do not charge into liquid, there are a large amount of air in the pipeline, ball float 5 drops on the bottom, illustrated just situation, its guide pillar 6 partial-lengths are inserted among the guide way 2, the usefulness of guiding during in order to rising.Guide pillar 6 is made up of guide pillar body 61 and sealing gasket 62, the section shape of guide pillar 6 is a regular hexagon, so just increased and guide way 6 guide holes between the gap, strengthened the flow of air, yet see between guide pillar 6 and the guide way 2 it is that the line of 6 lines contacts theoretically, reduced area of contact, also reduced the frictional force that endwisely slips, make its activity freely, because reducing of surface of contact, the discrete contact of surface of contact makes it might increase its quality of fit to reduce contact gap, thereby more can reduce side-friction, more can make ball float 5 freely up and down.

As shown in Figure 2; the utility model in use is mounted in the peak of hot-water heating system or other fluid pipeline systems; after when the pipe-line system topping up, passing through certain hour; ducted air can be discharged from through outlet pipe 4 overwhelming majority; at this moment ducted liquid enters in the valve body chamber by the external mouth of pipe 15 that is connected with pipeline; because ball float 5 is among the liquid; the buoyancy that liquid produces is greater than the weight of ball float 5; ball float 5 is progressively risen; last guide pillar 6 inserts guide way 2; sealing gasket 62 on the guide pillar 6 is encircled on the air exhaust loop 3 that is pressed in the guide way 2, and the two compresses, and has sealed the exhaust passage; exhaust process stops; but at this moment ball float 5 hemisphere in valve body 1 chamber can be retained in the partition chamber 11 all the time with the gas on top, thereby reach the purpose of gas barrier protection, make liquid medium not reach guide way.At this moment the air that cuts off in the chamber 11 can be subjected to certain compression, and compressed air can delivered energy promote ball float 5 whereabouts when removing water.
