Description
Technical field
The utility model belongs to valve technology field, relates to a kind of outlet valve, particularly a kind of automatic control pressure vent that is used for the hot-water heating pipe-line system.
Background technique
The air that accumulates in hot water heating and air conditioning pipe system is easy to generate the stifled phenomenon of gas, influence heat-transfer effect, the peak that solves way that air stops up and be at pipeline is provided with automatic control pressure vent, cause the heat supply actual effect not good because of exhaust is bad, and problem such as caused various heat supply accidents is of common occurrence.Often in the Fu Za heat supplying pipeline system, because of the gas that various factors produced, because the automatic control pressure vent performance failure in the pipe-line system, the gas that is detained in the pipe-line system can not be discharged, be to cause the pipe-line system circulation bad, even abrupt pressure increase the one of the main reasons of pipeline burst.
The disclosed a kind of novel pipeline automatic control pressure vent of existing drain tap such as Chinese patent literature [publication number: CN2799995], comprise valve body, valve gap, floating cup, wherein be provided with needle on floating cup top, the top of needle is cone, the valve gap center is provided with and the corresponding exhaust port of needle top cone, be provided with seal groove in the bonnet lower side, be provided with seal ring in the seal groove.When the outlet valve of this spline structure did not have air in valve body, floating cup buoyancy caused needle can not block corresponding exhaust port generation phenomenon of losing water inadequately, and sealing is relatively poor; Also rapid inadequately in whole exhaust process in addition.Existing other technological scheme also exists similar problem.
Summary of the invention
The purpose of this utility model is at existing existing the problems referred to above, and a kind of automatic control pressure vent of dismantling easy to maintenance, good sealing effect, can getting rid of gas in the pipeline rapidly is provided.
The purpose of this utility model can realize by following technical proposal: this automatic control pressure vent, comprise float, ending disconnected valve body and inside is the valve body of cavity, described float is arranged in the valve body, top at valve body is connected with valve gap, offer the outlet passageway that communicates with valve inner on the valve gap, above-mentioned only disconnected valve body is connected the bottom of valve body, described ending is equipped with air inlet spool and the spring one that acts on the air inlet spool in the disconnected valve body, end and to have on the disconnected spool and end the gas-entered passageway that the valve inner that breaks communicates, it is characterized in that, the exhaust plug with exhaust port is installed at described outlet passageway place, be connected with valve rod on the described exhaust plug, be set with spring two on the described valve rod, on valve rod the exhaust rubber cushion be installed, above-mentioned exhaust rubber cushion can shutoff under the effect of spring two or is opened exhaust port.
This automatic control pressure vent is a kind of device that is used to get rid of gas in the pipeline.An end that ends disconnected valve body is connected with pipeline, the other end that ends disconnected valve body is connected with valve body, when needing repairing, do not need to close the disconnected valve body of apolipsis, as long as unload valve body, be contained in the exhaust plug that ends in the disconnected valve body and under the effect of spring one, mention exhaust plug, the gas-entered passageway that ends on the disconnected valve body is closed, easy to maintenance.During work when in the valve body gas being arranged, gas pressure forces float to move downward, beam effect on the float is pressed down valve rod on valve rod, certain angle tilts between exhaust rubber cushion and the exhaust port this moment, thereby drive the exhaust rubber cushion and leave exhaust port, gas is discharged through exhaust port, realizes the automatic vent function.After gas was discharged from, the float come-up drove valve rod and is horizontal, and valve rod only is subjected to the effect of spring two, and the exhaust rubber cushion that is installed on the valve rod just tightly blocks exhaust port, realizes closing automatically.
In above-mentioned automatic control pressure vent, the bottom of described float is provided with kerve, and the both sides of described float are provided with side channel, and above-mentioned kerve and side channel are connected.Wherein gas enters that the kerve by float is passed to exhaust port through side channel again behind the valve body, makes things convenient for gas to separate with water like this, make water in the valve body remain on float below.
In above-mentioned automatic control pressure vent, described ending between disconnected spool and the only disconnected valve body is provided with seal ring.When unloading valve body, make only disconnected valve body gas-entered passageway and pipeline directly form sealing like this, improved the sealing between pipeline and the automatic control pressure vent.
In above-mentioned automatic control pressure vent, described ending on the disconnected valve body is fixed with polygonal prism.End the connection of breaking between valve body and the valve body by this prism easy-to-operat.
In above-mentioned automatic control pressure vent, a described end that ends disconnected valve body has the internal thread that is connected with valve body, and the other end is provided with the outside thread that is connected with pipeline.
In above-mentioned automatic control pressure vent, the top of described outlet passageway is equipped with bonnet.In case by screwing nut, make things convenient for the user to keep in repair when water leakage phenomenon appears in outlet valve like this vent closure.
Compared with prior art, advantage of the present utility model is:
1, owing to directly make under the effect by spring two the exhaust rubber cushion can shutoff or open exhaust port, have prevented from like this in the process of exhaust, to produce phenomenon of losing water, good seal performance, vent ratio is rapider.
2, when maintenance, do not need to close the disconnected valve body of apolipsis in addition, only need unload valve body, under the effect of spring two, mention exhaust plug, the gas-entered passageway that ends on the disconnected valve body is closed, keep in repair more convenient.
