Abstract
A kind of external band weight linear meter oil cylinder slow-closing check valve, including valve body, valve gap, flap is installed in valve body, flap connects has rocking bar, rocking bar to be rotatably connected in valve body, and valve body is provided with the drive shaft that drive rocker swings, the outer end of drive shaft is fixed with rocking arm; the outer end of rocking arm is connected in piston assembly, and the outer end of drive shaft is fixed with weight linear meter, and weight linear meter upwardly extends and is fixed with balancing weight on the top of weight linear meter.This structure is swung by piston assembly band motion rocker arm, and rocking arm drives flap to open and close by drive shaft, the Slow Close when oil cylinder of piston assembly can make closure of check ring, strength is little, and sound is little, and sealing surface wear is little, coordinate the weight linear meter in drive shaft, the sealing of flap can be strengthened, moreover it is possible to make regulation closed position.
Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of external band weight linear meter oil cylinder slow-closing check valve.
Background technology
Producing huge sound during current valve closing, sealing surface is produced immense pressure, sealing surface damages also fast, valve
Life-span is short.
Utility model content
This utility model to solve the problem that above-mentioned prior art exists, it is provided that a kind of external band weight linear meter oil cylinder Slow Close
Check-valves, Slow Close when external oil cylinder can make closure of check ring, strength is little, and sound is little, and sealing surface wear is little.
This utility model solve its technical problem use technical scheme: this external band weight linear meter oil cylinder Slow Close non-return
Valve, including valve body, valve gap, is provided with flap in valve body, flap connects has rocking bar, rocking bar to be rotatably connected in valve body, on valve body
Being provided with the drive shaft that drive rocker swings, the outer end of drive shaft is fixed with rocking arm, and the outer end of rocking arm is connected in piston assembly,
The outer end of drive shaft is fixed with weight linear meter, and weight linear meter upwardly extends and is fixed with balancing weight on the top of weight linear meter.This structure is led to
Crossing piston assembly band motion rocker arm to swing, rocking arm drives flap to open and close by drive shaft, and the oil cylinder of piston assembly can make check-valves close
Slow Close when closing, strength is little, and sound is little, and sealing surface wear is little, coordinates the weight linear meter in drive shaft, can strengthen the sealing of flap,
Regulation closed position can also be made.
In order to the most perfect, the outer section part of weight linear meter is arranged at intervals with hole, location, and balancing weight is provided with fastening spiral shell
Silk, fastening screw is positioned in hole, location.So can regulate balancing weight position on weight linear meter, therefore can regulate counterweight
The active force of bar.
The most perfect, the outer end of rocking arm is provided with the union joint of arc, and piston assembly is provided with spacing upper and lower at union joint
The limited block of end.
The most perfect, valve gap is provided with drain valve.
The most perfect, valve gap top is provided with suspension ring.
This utility model has the advantages that: this utility model structure closes Slow Close, sealing surface is produced power little；Flap closes
Close generation sound little, environmental-protection function；Sealing structure surface wear is little, and service life is longer；Weight linear meter can also make regulation closed position,
There is the advantages such as reliable, safe and environment-friendly.
