Set up separately on the port on thread head top respectively, the end connection end of the thread head, the top of the inner hole wall of thread head
It is equably provided at least two arc grooves downwards, the sphere is placed at the top port of thread head and by limit vertical plate
It is limited, the baffle is located at the top of limit vertical plate, and the arc groove makes the inner hole wall of sphere and thread head
Between form gap, the diameter of the sphere is greater than the diameter of circular hole and thread head internal control.
It is transition arc between the inner sidewall of the arc groove and thread head.
The double thread pipe nipple for connecting external elbow is provided at the gas outlet of the cylinder.
The bottom of the end is provided with the double thread pipe nipple for connecting external elbow.
The utility model has the beneficial effects that the utility model uses ball seal, valve body gas leakage and winter condensate are eliminated
Icing phenomenon reduces steam gas leakage loss, eliminates personal injury hidden danger；Sphere uses high-quality stainless steel making, there is good bullet
The effects of property, acid and alkali-resistance, anticorrosive, high temperature resistant；Sealing element easy to wear can be independently replaced, it is convenient for safeguarding, reduce equipment replacement
Expense improves putting equipment in service rate.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of Novel breather valve as shown in Figs 1-4, it is close including cylinder 1, hollow lower cover 2, diaphragm seal 3 and sphere 4
Mounting 3 is provided with baffle 11 between cylinder 1 and lower cover 2 in the Vapor outlet of cylinder 1,1 inner wall of cylinder is equipped with interior
Screw thread, the center on baffle 11 are provided with circular hole 12, the screw thread that the end 21 that there is lower cover 2 steam to enter, steam pass through
First 22 and four limit vertical plates 23, limit vertical plate 23 uniformly sets up separately on the port on 22 top of thread head respectively, thread head 22
End be screwed into end 21, the top of the inner hole wall of thread head 22 is equably opened downwards there are four arc groove 221, and sphere 4 is put
It is placed at the top port of thread head 22 and it is limited by limiting vertical plate 23, baffle 11 is located at the upper of limit vertical plate 23
Side, arc groove 221 make to form gap between sphere 4 and the inner hole wall of thread head 22, and the diameter of sphere 4 is greater than circular hole 12 and screw thread
The diameter of first 22 internal control.
It is transition arc 222 between arc groove 221 and the inner sidewall of thread head 22, transition arc 222 makes sphere 4 and screw thread
Gap between first 22 increases, and passes through the air in breather valve more unobstructed.
The double thread pipe nipple for connecting external elbow is provided at the gas outlet of cylinder 1, this elbow connects ambient atmosphere.
The bottom of end 21 is provided with the double thread pipe nipple for connecting external elbow, this elbow connects soot blowing steam valve.
The working process of the utility model is as follows: first the cylinder of breather valve 1 is fixedly connected with lower cover 2, then by lower end
The end 21 of lid 2 connects soot blower by elbow, and cylinder 1 is connected extraneous by elbow；When the starting of soot blower steam valve, by steaming
Steam pressure moves up breathing valve sphere 4, and sphere 4 withstands the circular hole 12 of baffle 11 after moving up, and can play good sealing function,
Greatly reduce steam leakage vapour loss in operation；When soot blower steam valve is closed, the sphere 4 of breather valve falls into four limits by gravity
In vertical plate 23, arc groove 221 formed between sphere 4 and the inner hole wall of thread head 22 gap, two neighboring limit vertical plate 23 it
Between gap, gap and gap can make smooth air by being connected inside breather valve with extraneous, guarantee that extraneous clean air passes through
The soot blowing gun barrel negative suction burner hearth of soot blower steam valve connection, prevents gun barrel and valve internal from being corroded and being worn by sulfur-bearing flue dust,
Extend soot blower service life.
The venthole of breather valve is higher than casing plane, inhibits the outflow of condensed water, it is therefore prevented that the generation of freezed in winter phenomenon,
It eliminates because icing falls the hidden danger hurted sb.'s feelings.
The utility model is inwardly cut in the outer surface two sides of the venthole of cylinder 1, and the top of cylinder 1 is made to form plush copper,
It is easier to be threaded in or out cylinder 1, it is easy to operate.
The utility model is inwardly cut in the two sides of the bottom of end 21, so that the bottom of end 21 is formed convex block, under being convenient for
End cap 2 is screwed into or back-outs.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
