Abstract
The utility model discloses a keg float liquid gravity type automatic exhaust valve. The utility model is characterized in that the bottom of a keg float in a valve cavity is provided with a communicating pipe, the inner cavity of the keg float and the inner cavity of a valve body are communicated by the communicating pipe, so that the inner part of the keg float can contain liquid and also has space for air; the keg float can be moved up and down along a guide rod, a valve core on the top of the keg float and a rubber ring between a valve cover and an air hole cover are driven to carry out the fit and the separation, and thereby, the exhaust and the closing functions can be achieved. The utility model is operated by the buoyancy, the operating pressure of a connecting device, and the gravity of liquid. The utility model has the advantages of simple structure, easy manufacture, and low cost. The utility model is suitable for a hot water boiler and a hot water heating system under the pressure bearing condition, the utility model can replace an air collecting device, and the utility model is also suitable for a similar pressure bearing liquid system.
Description
The utility model relates to outlet valve.
The present float type outlet valve that generally uses is because the in light weight and pressurized rapid wear of float; Valve body and valve gap be with being threaded, and only should work under the condition of normal pressure approaching, and is not suitable for artesian condition under and moves.Though Chinese patent 902019724 changes float into keg float, its keg float complex structure.
For overcoming the above-mentioned deficiency of float type outlet valve, the utility model provides a kind of steering capability good, and good sealing effect is easy to make, with low cost, and convenient the adjusting is suitable for the pail-floating liquid weight type automatic control pressure vent of working under artesian condition.
Main points of the present utility model are that the keg float of body cavity rises or descends along the guide rod that is installed in below the valve gap.Guide rod places in the gap between keg float and the valve body.Guide rod can be retrofitted on the valve interior wall, or installs the guiding fulcrum additional on the keg float periphery, is guide rail with the valve interior wall surface, reaches the leading role of keg float.The spool of keg float top center is a cone body, can close or open row's heart hole at air-vent cap center on the valve gap under the drive of keg float exactly, and rubber ring is equipped with in the air-vent cap bottom, and spool and rubber ring coincide, and become sealing.Cross over pipe is equipped with in the keg float bottom surface, with keg float inner chamber and body cavity UNICOM, makes the keg float internal and external pressure balance, and makes it can carrying liquid, and the gas space is arranged again.Can make shapes such as tapered, straight tube connecting tube.Between valve body and the keg float certain clearance is arranged, be used to that guiding device is set and collection is deposited gas, do not cause the switching of exhaust port too frequent.
Accompanying drawing is the structural drawing of the utility model-pail-floating liquid weight type automatic control pressure vent.
Valve gap in the accompanying drawing (1) is connected with bolt with valve body (6), and air-vent cap (2) center has exhaust port and is screwed onto valve gap (1) center, is convenient to maintenance and changes rubber ring (3), guarantees the sealing of spool (4) when closing exhaust port.Change the air-vent cap and the rubber ring in different exhausts aperture, can regulate the outlet valve size of high exhaust pressure.Guide rod (5) along the keg float periphery is housed on the valve gap (1), is used for the guiding of keg float (7) and the centering of spool (4) and exhaust port.
Outlet valve is vertically mounted on the high-order bit of system or equipment device or the position of gas collection easily.Earlier pack liquid into to cross over pipe (8) upper end-hole place in keg float (7) during installation, when outlet valve was communicated with the system or equipment device, liquid charged in the valve body (6), and the gas in the keg float (7) is sealed up for safekeeping in keg float.Liquid continues to charge into, the interior liquid level of valve body (6) raises, keg float (7) effect of portion's gas within it produces down buoyancy rises to coincide with rubber ring (3) until spool (4) and blocks exhaust port, and the internal pressure of simultaneity factor or apparatus also is added in the vent ports place as sealing force.Exhaust port is in closes the dress attitude, beginning gas collection in the valve body (6).The contained gas of liquid in the system or equipment device charges into earlier in the keg float (7) along taking over (9) and cross over pipe (8), when gas collects the lower end mouth of depositing to cross over pipe (8) in keg float (7), gas is deposited to the body cavity collection in keg float (7) outside, and forces liquid level to descend.Along with the decline of liquid level, the buoyancy of keg float (7) fades away.Liquid level further descends, when the deadweight that reaches spool (4), keg float (7) and the liquid weight sum more than the inherent valve pocket water line of keg float (7) when acting on the sealing force at vent ports place, keg float (7) drives spool (4) and falls, and exhaust port is opened.
The utility model is simple in structure, and is easy to manufacture, and working procedure does not need additionaling power and signal, automatic vent.Be applicable to the water-heating boiler and the hot water system that under artesian condition, move, can replace gas-collecting device, also be applicable to similar supporting roll system.
Claims (3)
1, a kind of pail-floating liquid weight type automatic control pressure vent, by valve gap (1), valve body (6), keg float (7), spool (4) and adapter (9) are formed, and it is characterized in that air-vent cap (2) center that is spirally connected on the valve gap (1) has exhaust port; The guide rod (5) that valve gap (1) is installed below is along keg float (7) periphery, and the guiding and rubber ring (3) centering of spool (4) below air-vent cap (2) that are used for keg float (7) are coincide; Guide rod (5) places in the gap between keg float (7) and the valve body (6).
2, pail-floating liquid weight type automatic control pressure vent as claimed in claim 1, it is characterized in that keg float (7) bottom surface is provided with cross over pipe (8), with keg float (7) inner chamber and valve body (6) inner chamber UNICOM, both making in the keg float (7) can carrying liquid, and certain gas space is arranged again; Cross over pipe (8) can be made shapes such as tapered or straight tube.
3,, it is characterized in that the guiding device guide rod (5) of keg float (7) can be retrofitted in the inwall of valve body (6) as claim 1,2 described pail-floating liquid weight type automatic control pressure vents; Also can install the guiding fulcrum additional at keg float (7) periphery, be the leading role that guide rail reaches keg float (7) with valve body (6) internal face.
