Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The technical program technical problem to be solved is：Existing micro-exhaust valve is complicated, and parts are more, adds
Work cost is high and sealing is easily failed.Particularly, existing micro-exhaust valve only has an exhaust outlet, and capacity is smaller, and one
Denier, which blocks, degassing function is failed.Existing micro-exhaust valve blocks air bleeding valve to solve the impurity in the medium of pipe network,
Need to increase a filter and one end connecting tube in air bleeding valve lower end, this method can increase air bleeding valve integral installation space
Add, while can also increase installation cost.
In order to solve the above-mentioned technical problem, as shown in figure 1, present embodiments providing a kind of micro row for carrying filtering function
Air valve, including valve body 13, the upper end of valve body 13 are provided with horizontal steam vent 14, gas collection chamber, gas collection are provided with valve body 13
Chamber is turned on by steam vent 14 with extraneous；
Float 10 is provided with gas collection chamber in valve body 13, float 10 is placed in gas collection chamber and received along gas
Collect chamber upper and lower displacement, there is the gap that supplied gas passes through between float 10 and valve body 13；
Valve body 13 is provided with primary sealing area 15 in gas collection top of chamber, and steam vent 14 is arranged on primary sealing area 15,
The upper end of float 10 is provided with secondary sealing area 20, when float 10 is located at uppermost position in fig-ure, primary sealing area 15 and secondary sealing area 20
Close contact forms sealing pair, and when float 10 is located at other positions, primary sealing area 15 is separated and is vented with secondary sealing area 20
Hole 14 turns on gas collection chamber and the external world.
The course of work of the technical program：This micro-exhaust valve is arranged in long distance water transfer pipe network, long distance water transfer pipe
A large amount of bubbles can be produced during network operation, the presence of these bubbles can hinder the normal operation of pipe network, reduce the conveying of pipe network
Efficiency, in severe case, bubble coalescence can rupture even booster to a certain extent, and the safe operation to pipe network produces very big prestige
The side of body.Therefore, it is necessary to set air bleeding valve to exclude bubble in pipe network.
As shown in figure 3, the float 10 in valve body 13 is in close contact under the buoyancy of liquid with valve body 13, the end of float 10
The secondary sealing area 20 in portion and the primary sealing area 15 of valve body 13 form sealing pair, and sealing pair is close by the steam vent 14 of valve body 13
Envelope, the medium in valve body 13 is blocked to the sealing function for realizing valve with the external world.
As shown in Fig. 2 overflow and gather in valve body 13 in gas from liquid in pipe network, the gas in valve body 13 is from floating
Gap between son 10 and valve body 13 rises to the top of gas collection chamber, and air accumulation can cause liquid level in valve body 13 to decline,
When liquid does not reach the secondary sealing force of valve seal to the buoyancy of float 10, float 10 declines so that gas is from valve body 13
Air bleeding valve is discharged, and realizes the purpose for discharging gas in pipeline.
The technical scheme that the embodiment is provided has the technical effect that：This micro-exhaust valve is simple in construction, and parts are few, close
Envelope is reliable, and processing cost is low；This air bleeding valve has 4-8 steam vent 14, and capacity can be promoted to 4-8 compared with existing air bleeding valve
Times, the function of Quick air-discharge can be achieved；Steam vent 14 is horizontally installed on the periphery of the upper end of valve body 13, and existing air bleeding valve needs
Son is capped on steam vent 14, horizontal exhaust is converted to by lid；The setting of multiple steam vents 14 solves single steam vent
14 once block the problem of causing degassing function to fail.
Float 10 and one embodiment that valve body 13 coordinates are as follows：The gas collection chamber includes cylindrical cavity 17 and conical cavity
16, valve body 13 forms primary sealing area 15 in the side wall of conical cavity 16, and float 10 includes cylindrical body and conical top, float
10 conical top is secondary sealing area 20, and the diameter of cylindrical cavity 17 is slightly larger than circular type body, conical cavity 16 and conical top
Match.Float 10 and valve body 13 in the present embodiment is simple in construction, good sealing effect.
The conical top is provided with top planes 18.The top planes 18 of conical top can have gas collection top of chamber
There is the space of bigger accommodating bubble, gas is easier to force down float 10 so as to which gas be discharged.
The steam vent 14 includes at least four.The setting of multiple steam vents 14 thoroughly solves single steam vent 14 once
The problem of blocking will make valve degassing function fail.
The inside of float 10 is provided with inner chamber 19.Float 10 can be lightweight material, or set inner chamber 19 to reduce float
10 weight.
