Abstract
The utility model relates to a novel hydraulic damper which comprises a head joint bearing, a tail joint bearing, a sleeve, a cylinder, a piston and double piston rods. The piston is a split type piston comprising a main piston and a secondary piston, the double piston rods include a main piston rod and a secondary piston rod, the main piston is connected with the main piston rod via a thread, the secondary piston is connected with the secondary piston rod via a thread, a hole throttle valve is arranged between the main piston rod and the secondary piston rod, a first cavity is arranged between the main piston and the secondary piston, the main piston rod is mounted on the sleeve, an oil flowing channel is reserved on the main piston rod, a second cavity is arranged between the main piston rod and the sleeve, and a third cavity is arranged between the secondary piston rod and the cylinder. The novel hydraulic damper is compact and simple in structure, reasonable in design, rapid in movement response, stable in performance, free of internal hydraulic oil leakage, needless for a secondary oil cup to compensate oil, and low in manufacturing cost, and meanwhile, size of the damper is reduced.
Description
Technical field
The utility model relates to a kind of damper, the especially a kind of damping of boiler tubing and novel hydraulic damper that protecting against shock destroys of applying to.
Background technique
At present, well-known, damper is to provide the resistance of motion, the device of depletion kinergety, the existing application widely in fields such as space flight, aviation, building, bridges.The damper of extensive use at present has: hydraulic damper, spring-damper, mechanical damper and viscous damper.Wherein, spring-damper is because complex structure, unstable properties, action response is slow, can only use in specific occasions, it is wider that hydraulic damper relies on its action response is fast, damping force is big advantage then to be used, but conventional single-rod piston hydraulic damper complex structure, need be provided with secondary lubricating cup to damper carry out repairing, volume is big, needs further technological improvement to adapt to other specific occasions.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and action response is fast, volume is little, the novel hydraulic damper of letting out in hydraulic oil does not have.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise the joint of head bearing, the caudal articular process bearing, sleeve, cylinder body, piston and piston rod, described piston is the split piston, form by main piston and sub-piston, described piston rod is a double piston-rod, comprise main piston rod and sub-piston bar, main piston is connected with main piston rod by screw thread, sub-piston is connected with the sub-piston bar by screw thread, between main piston rod and sub-piston bar, be provided with the hole throttle valve, and be provided with first chamber between main piston and the sub-piston, described main piston rod is installed on the sleeve, on main piston rod, offer the path that goes rancid, between main piston rod and sleeve, be provided with second chamber, between sub-piston bar and cylinder body, be provided with the 3rd chamber.
The utility model has the advantages that:
Compact structure is simple, reasonable in design, action response is fast, stable performance, let out in the no hydraulic oil, need not secondary lubricating cup damper is carried out repairing, reduce the volume of damper simultaneously, low cost of manufacture, the extension bar of tail end setting can be changed according to different use occasions and condition, makes the utility model application area wider, is convenient to penetration and promotion.
