Abstract
The utility model discloses a double-pole one-way valve device, which comprises a valve seat (1), pole valves and a fastener thereof, wherein the valve seat (1) and the pole valves are basically positioned on a straight line, the two pole valves (2-1) and (2-2) are arranged in the valve seat (1), a lining (4) is arranged at one end of the valve seat (1), a nut (5) for fixing the pole valves is arranged at the bottom of the lining (4), and a reset spring (3) is arranged in the two pole valves (2-1) and (2-2). Not only the safety spacing in up-and-down directions can be carried out after the double poles and the one-way valve of the utility model are combined, but also an oil cylinder has reliable up-and-down spacing, so that the whole structure is compact, thereby a hydraulic system oil passage is simplified.
Description
Technical field
The utility model relates to a kind of control valve unit, specially refers to a kind of Double Tops bar check valve apparatus.
Background technique
At present, the cylinder structure of domestic hydraulic pressure berth bogie mostly is jacking fixed oil cylinder of using and the sliding oil cylinder that turns to usefulness greatly, the employing machine security is spacing, when frame-steering, one-way valve by the oil cylinder two ends is controlled spacing, general one-way valve is can only folk prescription spacing to safety, can not well play the control position-limiting action, oil cylinder produces the phenomenon of string oil up and down, can not in time control oil cylinder when decommissioning, thereby the destruction oil cylinder, in the working life of shortening oil cylinder, also there is the not compact shortcoming of structure in traditional in addition one-way valve.
Summary of the invention
The utility model provides a kind of compact structure, spacing reliable Double Tops bar check valve apparatus.
In order to solve the problems of the technologies described above, the utility model provides a kind of Double Tops bar check valve apparatus, it comprises valve seat, top rod valve and fastening piece thereof, valve seat and top rod valve are positioned on the straight line substantially, be provided with two top rod valves in the valve seat, valve seat one end is provided with lining, and sleeve is provided with the nut of a fixed mandril valve, is provided with Returnning spring in two top rod valves.
Described valve seat top and lining middle part all are provided with " O " shape o-ring groove, described two top rod valves lay respectively at valve seat and lining one end, and two top rod valve length make it can be valve seat and the lining state of stretching out, the Returnning spring two ends are respectively in the circular groove of two top rod valve terminations, and be coupled condition with top rod valve, nut on lining, and with valve seat based on the straight line, described this Double Tops bar check valve apparatus is located in the piston.
After adopting as above technological scheme, Double Tops bar check valve apparatus is installed on the piston of sliding oil cylinder, be provided with two top rod valves in the valve seat, two top rod valves are positioned at valve seat and lining one end, both ends of the spring is located at respectively in the circular groove of two push rod terminations, and two top rod valves outwards push up under the elastic reaction of Returnning spring and stretch during running, and the safety of both direction was spacing about sliding oil cylinder can carry out, the oil cylinder that makes is spacing up and down reliable, prevents in the oil cylinder phenomenon of string oil up and down; Valve seat one end is provided with lining, and valve seat top and lining middle part are provided with " O " shape o-ring groove, and nut is located on the lining, not only improves its sealing, and plays good fixation; This device is set in the piston in addition can controls oil cylinder effectively, play the effect of protection oil cylinder, simplified the hydraulic system oil circuit after installing simultaneously.
