The accompanying drawing for needing to use is briefly described, it should be apparent that, drawings in the following description are only some implementations of the invention
Example, for those of ordinary skill in the art, without having to pay creative labor, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the overall structure diagram that the present invention has guider float-controlled exhaust value；
Wherein, 1 flange form piston；2 piston rods；3 first sealing rings；4 second sealing rings；5 packing rings；6 ball floats；7 steam vents.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
There is guider float-controlled exhaust value it is an object of the invention to provide one kind, deposited with solving above-mentioned prior art
Problem so that the automatic exhaust steam valve have compact conformation, sealed reliable, it is easy for installation the features such as.
What the present invention was provided has guider float-controlled exhaust value, including flange form piston, piston rod and ball float, method
Blue formula piston be used for be connected with the inner flange of tank of cooling down, piston rod pass through flange form piston bottom and with flange form piston seal
Laminating, piston rod is that some steam vents are evenly distributed with hollow piston rod, and the bar wall of piston rod, the end of piston rod with it is floating
Ball is fixedly connected；The bottom inner side of flange form piston offers the first seal groove, and the first sealing ring is provided with the first seal groove
For the sealing between piston rod and flange form piston, the end of flange form piston is provided with the second seal groove, on the second seal groove
It is provided with the second sealing ring.
When tank of cooling down is started working, gas flow is smaller, and ball float is moved upwards under buoyancy, and the first sealing ring is progressively
Steam vent is closed, after the gas in liquid is discharged to a certain degree, under the thrust of ball float, the first sealing ring is close with second
Seal is all closed, and potting of cooling down is closed；With the continuous accumulation of gas in tank of cooling down, gas pressure raises, forces and cool down in tank
Liquid level decline, ball float buoyancy reduces, and ball float drives piston rod to move downward, and the first sealing ring and the second sealing ring are opened, and lives
Steam vent on stopper rod exposes and gradually opens, and the gas in tank of cooling down begins through steam vent and is outwards exhausted, until gas
Body emptying, the liquid level cooled down in tank rises, and starts next new circulation.
It is below in conjunction with the accompanying drawings and specific real to enable the above objects, features and advantages of the present invention more obvious understandable
The present invention is further detailed explanation to apply mode.
Fig. 1 is refer to, wherein, Fig. 1 is the overall structure diagram that the present invention has guider float-controlled exhaust value.
As shown in figure 1, the present invention provides one kind a guider float-controlled exhaust value, flange form piston 1 with cool down
The inner flange connection of tank, and the different flat seal slot structure of twice set on the flange form piston 1, for placing not similar shape
The sealing ring of formula, the first sealing ring 3 placed in the first seal groove is radial seal O-ring, its role is to piston rod 2 with
Cool down and sealed between tank inner flange, it is ensured that under the thrust of ball float 6, piston rod 2 can keep straight up with
Cool down tank inner flange produce relative movement；The second sealing ring 4 placed in second seal groove is axial seal O-ring, piston
A packing ring 5 is provided between the bottom of bar 2 and ball float 6, after the gas flow in tank of cooling down reaches certain degree, on ball float 6
Rise, packing ring 5 offsets with flange form piston 1, reach the extreme position of the rising of ball float 6, the second sealing ring 4 is used to prevent from cooling down in tank
Liquid produce leakage spilling cool down outside tank.The combination of the sealing ring 4 of above-mentioned first sealing ring 3 and second so that this has guiding to fill
Float-controlled exhaust value is put, compact conformation, sealed reliable, installation also more facilitate.
Additionally, piston rod of the piston rod 2 for inner hollow, depending on its internal diameter can be according to capacity, different liquids are different
Capacity, can make install automatic exhaust steam valve when select the internal diameter of suitable piston rod 2 in advance；Uniformly divide on the bar wall of piston rod 2
The a number of steam vent 7 of cloth, the quantity and diameter in hole can also carry out using preceding advance choosing according to the difference of capacity
Select.
There is the specifically used process of guider float-controlled exhaust value as follows in the present invention：
When cool down tank start working when, gas flow is smaller, and ball float 6 is moved upwards under buoyancy, the first sealing ring 3 by
Step closes steam vent 7；
After the gas in liquid is discharged to a certain degree, under the thrust of ball float 6, packing ring 5 and the phase of the second sealing ring 4
Support, the position of ball float 6 rises to the limit, now the first sealing ring 3 and the second sealing ring 4 are all closed, and potting of cooling down is closed；
As the continuous accumulation of gas in tank of cooling down, gas pressure are raised, the liquid level cooled down in tank is forced to decline, ball float 6
Buoyancy reduces, and ball float 6 drives piston rod 2 to move downward, and the first sealing ring 3 is opened with the second sealing ring 4, the row on piston rod 2
Stomata 7 exposes and gradually opens, and the gas in tank of cooling down begins through steam vent 7 and is outwards exhausted, until gas emptying, disappears
Liquid level in gas tank rises, and starts next new circulation.
It should be noted that the first sealing ring 3 and the second sealing ring 4 are not limited to use O-ring in the present invention, also may be used
Using the sealing ring of other forms, to each fall within protection scope of the present invention.
Specific case is applied in the present invention to be set forth principle of the invention and implementation method, above example
Illustrate that being only intended to help understands the method for the present invention and its core concept；Simultaneously for those of ordinary skill in the art, according to
According to thought of the invention, will change in specific embodiments and applications.In sum, this specification content
Should not be construed as limiting the invention.
