Abstract

The utility model provides a kind of thickness adjustable hydraulic to seal serial component, and be made up of the ring packing ring of one group of thickness series, packing ring side has a circle seal groove, is embedded with " O " V-shaped ring in seal groove; The packing ring of described one group of thickness series comprises 3 packing rings that the packing ring of a base thickness H and base thickness H add 1/4 pitch L integral multiple, and its integer is 1,2,3, forms the serial packing ring that one group of thickness is respectively H, H+L/4, H+L/2, H+3L/4.The problem of scraping disconnected communication cable that the utility model can avoid winder arm cylinder displacement transducer to cause because wiring direction is not in place, improves the operating rate of unit; Effective raising sealing effect, avoids leakage of oil, reduces oil consumption, is conducive to improving operating environment; Avoid the displacement transducer damage accident caused because wiring direction cannot adjust, extend the life cycle of displacement transducer; Can be widely used in hydraulic equipment oil pipe connecting bend towards adjustment.

Description

A kind of thickness adjustable hydraulic sealing serial component

Technical field

The utility model belongs to hydraulic machinery field, and the adjustable thickness particularly relating to a kind of oil hydraulic cylinder for being threaded and sensor seals serial component.

Background technique

The winder arm cylinder of cold rolling mill continuous annealing unit and steel scrap press machine hold-down cylinder all with displacement transducer, to carry out detection and control to equipment moving position.Displacement transducer is inlet member, and be arranged on equipment oil hydraulic cylinder rear end cover, displacement transducer and oil hydraulic cylinder are threaded connection, and hydraulic oil is sealed by the seal ring that displacement transducer body installs additional.Find in Long-Time Service process, it is directive that connection due to displacement transducer connects, and wiring direction must be outwardly, and displacement transducer screw thread after screwing often wiring direction can not ensure just to be in direction outwardly, if now simple in order to ensure that wiring direction unscrews displacement transducer, just there will be leakage of oil.If displacement transducer screw thread screws rear wiring direction not words outwardly, then the communication cable of displacement transducer and winder frame are interfered, and communication cable very easily scraped pine, it is disconnected to scrape, and causes displacement transducer communicating interrupt, not only cause unit to occur parking accident, once cause steel scrap more than 40 tons; And directly cause coal gas and the energy loss of continuous annealing furnace.

Summary of the invention

The utility model aim to provide a kind of adjustable displacement transducer screw after wiring direction, prevent displacement transducer damage and cable scrape disconnected accident, and avoid leakage of oil thickness adjustable hydraulic seal serial component.

For reaching this object, the utility model takes following solution:

A kind of thickness adjustable hydraulic sealing serial component, it is characterized in that, be made up of the ring packing ring of one group of thickness series, packing ring side has a circle seal groove, is embedded with " O " V-shaped ring in seal groove;

The packing ring of described one group of thickness series comprises 3 packing rings that the packing ring of a base thickness H and base thickness H add 1/4 pitch L integral multiple, and its integer is 1,2,3, forms the serial packing ring that one group of thickness is respectively H, H+L/4, H+L/2, H+3L/4.

The beneficial effects of the utility model are:

1, the problem of scraping disconnected communication cable that winder arm cylinder displacement transducer causes because wiring direction is not in place can be avoided, improve the operating rate of unit;

2, effectively can improve sealing effect, avoid leakage of oil, reduce oil consumption, be conducive to improving operating environment;

3, avoid the displacement transducer damage accident caused because wiring direction cannot adjust, extend the life cycle of displacement transducer;

4, can be widely used in hydraulic equipment oil pipe connecting bend towards adjustment.

Accompanying drawing explanation

Fig. 1 is one group of thickness adjustable hydraulic sealing serial component figure;

Fig. 2 is thickness adjustable hydraulic sealing serial component installment state figure.

In figure: packing ring 1, seal ring 2, displacement transducer 3, oil hydraulic cylinder 4.

Embodiment

As seen from Figure 1, the utility model thickness adjustable hydraulic sealing serial component is made up of the packing ring 1 of one group of (4) thickness series, packing ring 1 is a ring, has a circle seal groove in the side of packing ring 1, is embedded with " O " V-shaped ring 2 in seal groove.

4 packing rings 1, thickness H based on comprising, the thickness of other 3 packing rings 1 is then that base thickness H adds 1/4 pitch L integral multiple, and its integer is 1,2,3, forms the serial packing ring 1 that one group of thickness is respectively H, H+L/4, H+L/2, H+3L/4.

Fig. 2 is thickness adjustable hydraulic sealing serial component installment state figure.During assembling, unload displacement transducer 3, the packing ring 1 of i.e. base thickness H the thinnest for thickness in assembly is installed to oil hydraulic cylinder 4 connecting end, then displacement transducer 3 is loaded onto and screws.Checking whether the wiring direction of displacement transducer 3 interferences when moving with winder body, as interfered, unloading displacement transducer 3 and changing packing ring 1, until do not interfere.

Claims (1)

1. a thickness adjustable hydraulic sealing serial component, it is characterized in that, be made up of the ring packing ring of one group of thickness series, packing ring side has a circle seal groove, is embedded with " O " V-shaped ring in seal groove;

The packing ring of described one group of thickness series comprises 3 packing rings that the packing ring of a base thickness H and base thickness H add 1/4 pitch L integral multiple, and its integer is 1,2,3, forms the serial packing ring that one group of thickness is respectively H, H+L/4, H+L/2, H+3L/4.
