Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The purpose of this utility model, which is to provide one kind, guider float-controlled exhaust value, to solve above-mentioned existing skill
The problem of art is present so that the automatic exhaust steam valve have compact conformation, sealed reliable, it is easy for installation the features such as.
What the utility model was provided has a guider float-controlled exhaust value, including flange form piston, piston rod and floating
Ball, flange form piston is used to be connected with the inner flange for tank of cooling down, and piston rod is lived through the bottom of flange form piston and with flange form
Palette is filled in, 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
End is fixedly connected with ball float；Offered on the inside of the bottom of flange form piston in the first seal groove, the first seal groove and be provided with first
The sealing that sealing ring is used between piston rod and flange form piston, the end of flange form piston is provided with the second seal groove, and second is close
The second sealing ring is provided with sealing groove.
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 and second close
Seal is all closed, and potting of cooling down is closed；With the continuous accumulation of gas in tank of cooling down, gas pressure rise is forced and cooled 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 opened, 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.
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model.
Fig. 1 is refer to, wherein, Fig. 1 is that the overall structure that the utility model has guider float-controlled exhaust value is shown
It is intended to.
As shown in figure 1, the utility model, which 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 the twice that are set on the flange form piston 1, for placing not
With the sealing ring of form, the first sealing ring 3 placed in the first seal groove is radial seal O-ring, and its role is to piston
Sealed between bar 2 and tank inner flange of cooling down, it is ensured that under the thrust of ball float 6, piston rod 2 can be kept straight up
Produce relative movement with the inner flange of tank of cooling down；The second sealing ring 4 placed in second seal groove is axial seal O-ring,
A packing ring 5 is provided between the bottom of piston rod 2 and ball float 6, after the gas flow in tank of cooling down reaches certain degree, ball float
6 rise, and packing ring 5 offsets with flange form piston 1, reach the extreme position that ball float 6 rises, and the second sealing ring 4 is used to prevent from cooling down
Liquid in tank produces leakage spilling and cooled down outside tank.The combination of the above-mentioned sealing ring 4 of first sealing ring 3 and second so that this is led
To device float-controlled exhaust value, compact conformation, sealed reliable, installation also more facilitate.
In addition, piston rod 2 is the piston rod of 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 suitable internal diameter of 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 the advance choosings before uses according to the difference of capacity
Select.
There is the specifically used process of guider float-controlled exhaust value as follows in the utility model：
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；
With the continuous accumulation of gas in tank of cooling down, gas pressure rise forces the liquid level cooled down in tank 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 opened, 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 utility model,
The sealing ring of other forms can also be used, protection domain of the present utility model is each fallen within.
Apply specific case in the utility model to be set forth principle of the present utility model and embodiment, the above
The explanation of embodiment is only intended to help and understands method of the present utility model and its core concept；Simultaneously for the one of this area
As technical staff, according to thought of the present utility model, will change in specific embodiments and applications.To sum up
Described, this specification content should not be construed as to limitation of the present utility model.
