Description
Technical field
The utility model relates to a kind of high-pressure vacuum breaker component, in particular to a kind of high-pressure vacuum breaker oil
Buffer structure.
Background technique
Currently, buffer structure in the market, is all to achieve the purpose that buffering by ball come current limliting, the effect of buffering is poor,
It is low to control precision, killer switch rebound is big.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of high pressure vacuum open circuit
The oily buffer structure of device.
To achieve the goals above, the measure that the utility model is taken:
A kind of oily buffer structure of high-pressure vacuum breaker, the main shaft connecting lever including lubricating cup body and for breaker contact
Piston rod is provided with an open-ended oil pocket in the lubricating cup body, and the opening of oil pocket is sealedly connected with end cap,
The inner end of piston rod is set in oil pocket, and oil pocket is separated into two chambers, the outer end of piston rod by the piston portion of piston rod inner end
The outside of lubricating cup body is reached across end cap, and the oil leak hole of connection two chambers is offered on the piston portion of piston rod inner end；
The aperture of the oil leak hole is 2.05 millimeters；
The outer end of the piston rod is arranged with cap pad；
It is provided with reset spring in the oil pocket, one end of reset spring presses against on the inner bottom plating of oil pocket, the other end
Press against the inner end of piston rod.
The utility model has the beneficial effects that practical, production cost is low, structure novel, and killer switch rebound is small, improves
The precision of control also improves the quality and safety of high-pressure vacuum breaker.
Detailed description of the invention
Fig. 1, the planar structure schematic diagram of the utility model.
Specific embodiment
A kind of oily buffer structure of high-pressure vacuum breaker, the main shaft connecting lever including lubricating cup body 3 and for breaker connect
The piston rod 1 of touching, an open-ended oil pocket 5 is provided in the lubricating cup body 3, and the opening of oil pocket 5 is tightly connected
There is end cap 2, the inner end of piston rod 1 is set in oil pocket 5, and oil pocket 5 is separated into two chambers by the piston portion 102 of 1 inner end of piston rod
Room, the outer end of piston rod 1 pass through the outside that end cap 2 reaches lubricating cup body 3, the company of offering on the piston portion 102 of 1 inner end of piston rod
The oil leak hole 101 of logical two chambers.
The aperture of the oil leak hole 101 is 2.05 millimeters.
The outer end of the piston rod 1 is arranged with cap pad 6.
Reset spring 4 is provided in the oil pocket 5, one end of reset spring 4 presses against on the inner bottom plating of oil pocket 5, is another
One end presses against the inner end of piston rod 1.
The working principle of the utility model is: when breaker open operation, the main shaft connecting lever (installation is on-board the circuit breaker) of breaker,
The outer end that piston rod 1 can be touched ahead of time, pushes piston rod 1 to move down, due to only passing through draining between two chambers
Draining is carried out in hole 101, and breaker open operation speed is controlled by the flow of oil leak hole 101, so that breaker is reached point by design requirement
Lock time and speed guarantee that switch separating brake spring reaches required value, and after switch closes a floodgate, reset spring 4 does work, and keeps piston rod 1 multiple
Position.
The utility model is to open up diameter on the piston portion 102 of piston rod 1 by calculating and be 2.05 millimeters and let out
Oilhole 101 can make in breaker open operation, and oily flow velocity reaches 0.12L/s, and optimum flow rate guarantees switch rebound very little,
Reach the rebound within the scope of 0.8 millimeter, improves the precision of product.
