Abstract
The utility model discloses an automatic exhaust valve, which is mainly used for automatically exhausting for a heating system. The utility model is provided with a valve body 1, wherein, one end of the valve body 1 is provided with an interface, and the other end of the valve body 1 is provided with a valve nozzle 4; the inner part of the valve body 1 is also provided with a float 2; a sealing element 6 which is matched with the valve nozzle 4 is arranged on the float 2. The utility model has the advantages of convenience, timeliness, automation, etc.
Description
The utility model belongs to a kind of venting gas appliance, particularly a kind of automatic control pressure vent that is used for heating system.
In heating system, venting gas appliance all is housed, existing venting gas appliance is the plug form, operation manually, exhaust is untimely, the influence heating.
The purpose of this utility model provides a kind of convenience automatic control pressure vent timely.
Technical solution of the present utility model is: a kind of automatic control pressure vent is characterized in that: be provided with valve body 1, valve body 1 one ends are provided with interface, and the other end is provided with valve nozzle 4, also are provided with float 2 in the valve body 1, and the Sealing 6 that is complementary with valve nozzle 4 is housed on the float 2.
Be provided with valve gap 3 between described valve nozzle 4 and the valve body 1, be scyewed joint between valve gap 3 and valve body 1, the valve nozzle 4, Sealing 6 is positioned at the guide hole 11 on the valve gap 3, is provided with gap or groove between guide hole 11 and the Sealing 6.
Described float 2 is hollow stainless steel spheroid.
Be provided with filter plate 10 in the described valve body 1.
The utility model compared with prior art has automatically, in time, advantage such as convenient.
Below in conjunction with the drawings and the specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure: 1 is valve body, and the lower end of valve body 1 is provided with tapped interface 13.During installation interface 13 connected with the pipeline of system and get final product.Install for convenience, also be provided with an interface 14, get final product when connecting with interface 14 interface 13 screw-in plugs to be sealed at one's leisure in side of valve body.
The upper end screw thread of valve body 1 is connected with a valve gap 3, is provided with sealing gasket 7 between valve gap 3 and the valve body 1.The center of valve gap 3 is provided with guide hole 11, and guide hole 11 top scyewed joint have valve nozzle 4 (as figure).The cover 8 that joins with stainless steel hollow float 2 moving up and down is equipped with in the below of guide hole 11, in the cover 8 Sealing 6 is housed, plane and valve nozzle 4 bottom nozzles coupling leaves the gap or vertically be provided with groove 12 on guide hole 11 madial wall between cover 8 and the valve gap 3 on the Sealing 6.In valve body 1, be provided with a filter plate 10 below the float 2, and fixing by spring clip 9.Scyewed joint has bonnet 5 on the described valve nozzle 4, and bonnet 5 is provided with the hole 15 with valve nozzle 4 inner chamber UNICOMs.
During use with interface 13 or 14 and system join, after being full of water in the system, move because float 2 effect drives on the Sealings 6, overlap 8 this moment and guide hole 11 in, upwards move, make on the Sealing 6 plane shut 4 end of valve nozzle mouth.When producing a large amount of gas when emitting intrasystem water or in the system, float 2 loss of buoyance effects, and under will make that plane and 4 end of valve nozzle mouth break away from the Sealing 6, gas from the hole 15, valve nozzle 4 enters, and by overlap 8 and valve gap 3 between the gap or the groove 12 on the valve gap 3 enter in the system.When system Nei Shui rose once more, internal gas was discharged along inlet passage, and when water level rose to float 2 places, float was subjected to floating function once more, and shuts valve nozzle 4.Reach the automatic vent purpose.
