Abstract
The utility model discloses a kind of cylinder valve, including bonnet, hydraulic cylinder, piston rod, it is vented cover plate, flap, cylinder and valve body, the bonnet is located at the top of the valve body, the lower end of the bonnet is connected with the hydraulic cylinder, and the inside of the hydraulic cylinder is provided with piston rod, and the both sides of the piston rod are provided with exhaust cover plate, it is described exhaust cover plate lower end and the flap is connected with the both sides of the piston rod, the lower semisection inside middle of the valve body is provided with cylinder.The utility model drag-reduction energy-saving, reduces pressure oscillations, and security is improved；Pipeline when there is negative pressure can gas injection, moved by the change piston rod of air pressure, so as to which pipeline is blocked and turned on, so as to the circulation of liquid in control pipeline.
Description
Technical field
It the utility model is related to valving, and in particular to a kind of cylinder valve.
Background technology
The flow control for setting valving to carry out tin cream is frequently necessary in existing automation tin cream packaging facilities, is commonly used
Be to use cylinder valve, but existing cylinder can not control the precision controlling of tin cream flow well, commonly using can also make
The sealing of cylinder declines, so as to cause error larger.
Utility model content
A kind of the problem of the purpose of this utility model is to overcome prior art to exist, there is provided cylinder valve.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：
A kind of cylinder valve, including bonnet, hydraulic cylinder, piston rod, cover plate is vented, flap, cylinder and valve body, the bonnet are set
At the top of the valve body, the lower end of the bonnet is connected with the hydraulic cylinder, and the inside of the hydraulic cylinder is provided with piston rod, institute
State piston rod both sides be provided with exhaust cover plate, it is described exhaust cover plate lower end and be connected with the valve in the both sides of the piston rod
Valve, the lower semisection inside middle of the valve body are provided with cylinder, set on the side drift angle between the hydraulic cylinder and be vented cover plate
There is inductor.
Further, the upper end of the exhaust cover plate is provided with exhaust outlet.
Further, it is connected on the bonnet with one end of pressure-equalizing pipe.
Further, the other end of the pressure-equalizing pipe is connected on pressure balance block.
Further, connected between the pressure balance block and cylinder by connecting tube.
The beneficial effects of the utility model:
The utility model drag-reduction energy-saving, reduces pressure oscillations, and security is improved；Pipeline can be noted when there is negative pressure
Gas, moved by the change piston rod of air pressure, so as to which pipeline is blocked and turned on, so as to liquid in control pipeline
Circulation.
