Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the enlarged diagram at Figure 1A of the present invention.
Specific embodiment
Below in conjunction with attached drawing, specific embodiments of the present invention will be described in further detail.
It being provided by Fig. 1 and Fig. 2, a kind of efficient high-speed exhaust valve, the valve body 1 including tubular, the lower part of valve body 1 is import,
The top of valve body 1 is outlet, and 1 top of valve body is equipped with the valve deck 2 of sealing outlet, is placed with floating ball 3, floating ball 3 in the valve body 1
Top be fixed with guide rod 4, which is characterized in that the guide rod 4, which stretches out valve deck 2 upwards and slides up and down with valve deck 2, to be connect, valve deck 2
On be fixed with support frame 5, support frame 5, which slides up and down, is connected with the first bar 6, and 6 upper end of the first bar is coaxially fixed with the second bar 7,
Two bars, 7 upper end is coaxially fixed with third bar 8, and the second bar 7 slidably connects U-shaped block 9, and the first bar 6 cannot pass through U-shaped block 9, U-shaped
The lower end of block 9 is slidably connected with the second bar 7, and upper end and the third bar 8 of U-shaped block 9 are slidably connected, the company of the first bar 6 and the second bar 7
The secondary spring 10 being fixed between 9 both ends of U-shaped block between the place of connecing and the lower end of U-shaped frame is fixed on support frame 5 and is located at
Limited block 11 away from the side that U-shaped block 9 is open, U-shaped block 9 are equipped with downwards away from the one side lower part of opening to away from U-shaped block 9
The inclined surface 12 of opening direction, the limited block 11 are equipped with limit hole of the opening towards U-shaped block 9, are slidably connected in limit hole
There is spacer pin 13, spacer pin 13 is contacted away from one end of U-shaped block 9 with inclined surface 12, between the bottom and spacer pin 13 of limit hole
Equipped with the spacing compression spring 14 that spacer pin 13 is pressed to U-shaped block 9, the valve deck 2 is equipped with venthole 17, is fixed with control on U-shaped block 9
Bar 15 processed, inner wall is fixed with valve seat 16 on valve deck 2, and valve seat 16 is equipped with the through hole 18 opposite with venthole 17, and control-rod 15 is worn
It crosses venthole 17 and through hole 18 enters in valve body 1, control-rod 15 slidably connects spool 19, and spool 19 and valve seat 16 cooperate
Through hole 18 is sealed, one end end that valve rod protrudes into valve body 1 is fixed with fixed lobe 20, pacifies between fixed lobe 20 and spool 19
Equipped with Packing spring 21.
When valve body 1 contains less gas, floating ball 3 is located at topmost under the action of buoyancy, and secondary spring 10 is in
Not by 8 compressive state of third bar, while U-shaped block 9 is also at topmost, and spacer pin 13 is contacted with the lowest part of inclined surface 12, control
Bar 15 processed also is located at topmost, and Packing spring 21 stores power by compression, and Packing spring 21 compresses spool 19, and then 19 sealing valve of spool
The through hole 18 of seat 16.As 1 gas of valve body increases, water level decreasing in valve body 1, buoyant spheres fall, and drive third by guide rod 4
Bar 8 declines, and compresses secondary spring 10, is not enough to overcome the resistance between spacer pin 13 and inclined surface 12 in the storage power of secondary spring 10
When power, the displacement of U-shaped block 9 generation very littles, therefore spool 19 is in the state of sealed valve core 19, when gas continues growing, floating ball 3
Third bar 8 is pulled to continue to decline by guide rod 4, third bar 8, which compresses secondary spring 10, to be continued to store power, until the storage of secondary spring 10
When power overcomes the resistance between spacer pin 13 and inclined surface 12, U-shaped block 9 is rapidly moving downward under the action of secondary spring 10,
Away from the vertical face contact being open, U-shaped block 9 drives Packing spring 21 to decline by control-rod 15 for spacer pin 13 and U-shaped block 9, into
And spool 19 is opened and the gas in valve body 1 is discharged.After the gas in valve body 1 is discharged, water will push floating ball 3 to move up,
Floating ball 3 moves up, and then the first bar 6, the second bar 7 move up, and the second bar 7 passes through U-shaped block 9 and is slidably connected with U-shaped block 9, the
One bar 6 cannot pass through U-shaped block 9, and the first bar 6 will push up U-shaped block 9 and move up, and U-shaped block 9 moves up so that control-rod 15 drive it is close
Envelope spring 21 moves up, and Packing spring 21, which can store, forces tight spool 19, makes the through hole 18 of 19 seal valve seat 16 of spool.
The through hole 18 is cylindrical hole, penetrates through the via hole 22 that the side close to spool 19 is equipped with taper, and spool 19 is
It is round table-like.Increase via hole 22 and sets round table-like for spool 19, so that the sealing effect of valve body 1 and spool 19 is more preferable, energy
Enough reduce the abrasion between spool 19 and valve body 1.
The valve body 1 is removably installed with valve deck 2, and valve deck 2 and valve body 1 are bolted to connection.In valve body 1 and valve
Core 19 wear it is more serious, sealing effect reduce when, valve body 1 can be removed and spool 19 is replaced, in a disguised form extend the exhaust
The service life of valve reduces use cost.
The spacer pin 13 is arcwall face close to one end end of U-shaped block 9.
First bar 6, the second bar 7, third bar 8 are structure as a whole, and step, platform are equipped between the first bar 6 and the second bar 7
Rank limits the first bar 6 and enters in U-shaped block 9 and U-shaped block 9 can be pushed to move.
The input end of the valve body 1 is equipped with flange arrangement 23.Flange arrangement 23 is convenient for being installed with corresponding pipeline.
The beneficial effects of the present invention are: when the intracorporal gas of valve increases to certain value, spool can open rapidly into
Row exhaust, reduces the opening and closing time of valve, effectively increases the service life of valve；Valve seat is detachably connected with valve deck, so that
The replacement of valve seat is convenient, when the prooving of valve seat is serious, can valve seat be repaired or be replaced.
Embodiment described above is not intended to limit the scope of the present invention, before not departing from design concept of the present invention
It puts, the various changes and improvements that those skilled in the art make technical solution of the present invention should all be included in the present invention
Claims determine protection scope in.
