Abstract
The utility model relates to a double cylinder type hydraulic pressure stepless regulator which comprises an inner cylinder, an outer cylinder and a valve core. The outer cylinder is positioned on the outside of the inner cylinder; the outer and the inner cylinders are coaxial parallel; a gap is arranged between the two cylinders; the middle part of the inner cylinder is provided with a piston; a connecting rod which is connected to the piston is connected with an outer displacement or angle pre-regulating mechanism. The open or the closure of the valve core is controlled to lock the piston at any position in the inner cylinder; thus the outer pre-regulating mechanism is locked, and the stepless hydraulic regulation is achieved. The utility model has the advantages of good counter-tup performance and strong practicability.
Description
The utility model relates to stepless regulator, specifically is a kind of two-cylinder type hydraulic stepless regulator.
Existing hydraulic regulating device is the single cylinder structure, when cylinder body is subjected to clashing into, deformation takes place, and causes piston not move in cylinder, causes whole controlling device to scrap.For fear of bump deformation, the cylinder body barrel will the very high material of selection intensity, and suitably increases wall thickness and cause cost to rise.
The purpose of this utility model just provides a kind of crash-proof two-cylinder type fluid pressure governor.
The purpose of this utility model is achieved in that a kind of hydraulic stepless controlling device, comprises inner cylinder tube, outer cylinder, spool, and described outer cylinder is outside inner cylinder tube, and is and parallel with inner cylinder tube, and there is a gap centre, as pressurized gas and hydraulic oil channel; The inner cylinder tube left end ring washer that has been fixedly connected, there is a gas-liquid channel at the ring washer middle part, an end of this passage with described in gap between the outer cylinder communicate, the other end communicates with inner cylinder tube left side inner room, the preceding seal-seating of this ring washer left end connection, preceding seal-seating is embedded with seal ring; Be full of pressurized gas and hydraulic oil in the described inner cylinder tube, there is a piston at the middle part, and the piston left end connects a connecting rod, and the mechanism that connecting rod and outside desire are regulated displacement (angle) links; Described inner cylinder tube right-hand member is connected with the back sealing seat, back sealing seat is embedded with the back seal ring, the sealing seat has pressurized gas and hydraulic oil channel, this passage one end with described in gap between the outer cylinder communicate, the other end communicates by the inner room of spool with the inner cylinder tube right side, back sealing seat has described spool, and the spool right-hand member connects a controlling rod.
Do the time spent when the external force that controlling rod is subjected to left, push spool to left end, the gas-liquid channel of back sealing seat and inner cylinder tube right side inner room UNICOM make the piston left side and right pressurized gas and hydraulic oil UNICOM, and connecting rod can promote piston motion; External adjustment mechanism is transferred to when needing the position, spool moves right, and closes being communicated with of back sealing seat passage and inner cylinder tube right side inner room, and piston just is locked in the fixed position, external adjustment mechanism is just locking thereupon also, thereby reaches the purpose of step-less adjustment displacement or angle.The utility model device needing can be used for the equipment of adjusting angle or straight-line displacement.
Because piston only moves in inner cylinder tube, inner cylinder tube is in outer cylinder inside.Therefore, when this device is subjected to external force collision, can not change the inner cylinder tube shape, and damage device, and the suffered fluid pressure in the inside and outside two sides of inner casing barrel equates that manufactured materials is less demanding that cost is low, applicability is wide.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing is the utility model sectional view.
Among the figure:
1, connecting rod 2, preceding sealing seat 3, outer cylinder 4, preceding seal ring 5, ring washer 6, inner cylinder tube 7, interior outer cylinder gap 8, piston 9, spool 10, back sealing seat 11, back seal ring 12, controlling rod 13, back sealing seat gas-liquid channel 14, ring washer passage.
Between inner cylinder tube (6) and the outer cylinder (3) gapped (7), the left end of inner cylinder tube (6) is connected with ring washer (5), there is a gas-liquid channel (14) at ring washer (5) middle part, one end of passage (14) communicates with gap (7), the other end communicates with inner cylinder tube (6) left side inner room, sealing seat (2) before the left end of ring washer (5) connects is embedded with seal ring (4) on the preceding sealing seat (2); Inner cylinder tube is full of pressurized gas and hydraulic oil in (6), and there is a piston (8) at the middle part, and piston (8) left end is associated with a connecting rod (1), and the mechanism that the other end of connecting rod (1) and outside desire are regulated displacement or angle links; Inner cylinder tube (6) right-hand member connects back sealing seat (10), be embedded with back seal ring (11) on it, one has pressurized gas and hydraulic oil channel (13) in the back potting seat (10), passage (13) one ends are opened and can be communicated with inner cylinder tube (6) right side inner room through spool (9), and the other end communicates with gap (7).There is spool (9) at the middle part of back sealing seat (10), and the right-hand member of spool (9) is connected with controlling rod (12).
