Abstract
The utility model provides an exhaust valve, belonging to the valve technical field, which solves the problems of the prior exhaust valve that: when the exhaust valve is in need for repair, it is also necessary to close up a pipeline connected with the valve and the repair is very not convenient. The exhaust valve comprises a valve body with a hollow cavity inside, a valve core assembly for exhaust in the valve body, a connection pipe body with an air inlet channel and connected with an air inlet of the valve body, a plug head arranged in the air inlet channel and capable of returning and closing the air inlet channel when the valve body is disassembled from the connection pipe body, a spring 1 mounted between the plug head and the connection pipe body, wherein one end of the spring 1 acts on the plug head and another end acts on the connection pipe body. When the exhaust valve is in need for repair, it is not necessary to close up a pipeline connected with the valve and it is only necessary to disassemble the valve body, thus the plug head plugs the air inlet channel of the connection pipe body and the repair is relatively convenient. In addition, the sealing performance of the whole exhaust valve is good, the water leakage is prevented during the exhaust process and the exhaust is relatively quick.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of venting gas appliance, particularly a kind of outlet valve that is used for getting rid of hot-water heating pipe-line system gas.
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 pipeline automatic control pressure vent of Chinese patent literature [publication number: CN2497119] for example, comprise gas cap, valve, cursory, frame and closed joint, gas cap is threaded with valve, rubber cushion is arranged in the gas cap, there is exhaust port the gas cap side, valve is threaded with frame, the taper inlet hole is arranged below the valve, the taper inlet hole is threaded with valve, be lined with sealing gasket above the taper inlet hole, cursory in frame, seal rubber pad is arranged at cursory top, and closed joint is threaded with frame.When this automatic control pressure vent uses closed joint is connected with pipeline, during work mainly be by seal rubber pad open or the shutoff valve in pore realize exhaust process, the outlet valve of this structure also needs to close coupled pipeline when needing repairing as can be seen, keeps in repair very inconvenient.After exhaust finished, the sealing rubber cushion can not block the pore in the gas shutoff mouth and produce phenomenon of losing water in addition, and sealability is relatively poor.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 good sealing effect is provided, can gets rid of gas in the pipeline rapidly, dismounting outlet valve easy to maintenance.
The purpose of this utility model can realize by following technical proposal: a kind of outlet valve, comprise the inner valve body of cavity that is, be provided with the mangetic core assembly that is used for exhaust in the described valve body, it is characterized in that, the suction port place of described valve body connects the adapter body with gas-entered passageway, be provided with the plug that when the adapter body is pulled down, can return and block gas-entered passageway when valve body in the described gas-entered passageway, between plug and adapter body, spring one is installed, one end of described spring one acts on the plug, and the other end acts on to be taken on the body.
In above-mentioned outlet valve, described mangetic core assembly comprises float, described float is arranged in the valve body, on valve body, offer the export and import that communicates with its inside, described outlet port is equipped with the spool with exhaust port, be connected with valve rod on the described spool, be provided with spring two between valve rod and spool, described valve rod is provided with the exhaust rubber cushion that matches with exhaust port.
Wherein float is hung on the valve rod, and spring two has certain elasticity pretightening force to make the exhaust rubber cushion on the valve rod block exhaust port.During use an end and the valve body of taking over body are linked together, the other end is connected with pipeline.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.
Only need pull down valve body from taking over body when needing repairing, plug is return and blocked gas-entered passageway under the effect of spring one like this, and is more convenient when keeping in repair like this.
In above-mentioned outlet valve, be provided with seal ring one between described plug and the adapter body, be Chang Kai or normally closed being sealed and matched between sealing circle one and the adapter body.Wherein the sealing circle is when valve body is pulled down from taking over body, makes seal ring one and take over body to form sealing, prevents that the fluid in the pipeline from further flowing in the adapter body.
In above-mentioned outlet valve, an end of described adapter body has the internal thread that is connected with valve body, and the other end has the outside thread that is connected with pipeline.
In above-mentioned outlet valve, the joint of described adapter body and valve body is provided with seal ring two, has the annular groove that is complementary with sealing circle two on the described adapter body.Strengthened taking over the sealability of joint between body and the valve body like this, prevented to produce and leak.
In above-mentioned outlet valve, described plug is cylindric, and its middle part has several equally distributed breach.When plug was in open mode, the fluid in the pipeline just entered in the valve body from this breach like this.
In above-mentioned outlet valve, described breach quantity is three.
Compared with prior art, the advantage of this outlet valve is when outlet valve needs repairing, and does not need to close coupled pipeline, only needs dismounting valve body down, return and blocked the gas-entered passageway of taking over body at the effect lower end cap of spring one like this, keeped in repair more convenient.Whole in addition outlet valve good seal performance, prevent to produce water leakage phenomenon in the process of exhaust, exhaust also relatively rapidly.
