Description
Technical field
The present invention relates to a kind of temperature compensation means, belongs to hydraulic pressure alarm field, can experience oil liquid temperature in real time and make
Compensation, especially suitable for preventing false alarm during hydraulic system cold-starting.
Background technology
Temperature instruction structure has low temperature locking and high temperature unblock two states, and when fluid low temperature, indication piece is in locking shape
State, prevent when system hypothermia from starting because oil viscosity causes greatly the increase of filter core forward and backward pressure difference and caused by false alarm, when fluid follows
Circumstance temperature degree unlocks after reaching set point of temperature.Current existing temperature lock structure is usually located at housing epicoele because structure limits,
Do not contacted directly with fluid, there is certain hysteresis quality.The New temperature lock structure real-time perception oil liquid temperature, can instantaneously do
Go out reaction, high sensitivity.
The content of the invention
The task of the present invention is to propose a kind of real-time perception oil temperature, willing temperature lock structure.
The task of the present invention, which is done in such a way that, is characterized in that：The technical program include instruction component, little spring, on
Housing, sensory package, piston component, spring, lower house, the instruction component are made up of magnet and protective cap, and the magnet is
Nian Jie with protective cap by high-temp glue, the instruction component is assemblied in the upper end of upper casing intracoelomic cavity；It is machined with indicator assemblies
Assemble the groove of little spring；Upper shell is connected by screw thread with hydraulic system；The sensory package is made up of guide rod and temperature-sensitive element,
Temperature-sensitive element is riveted on guide rod, and sensory package is assemblied between upper shell and lower house；The piston component is by piston, sealing
Circle, guard circle are formed, and sealing ring and guard circle are cased with piston, and piston component is assemblied in upper casing intracoelomic cavity lower end, added on piston
Work has mounted elastically groove；Lower house and upper shell are connected through a screw thread.The piston component and sensory package are Split type structure.
Lower house and upper shell are connected through a screw thread.
The present invention has the following effects that：The present invention has the advantages that small volume, in light weight, compact-sized, high sensitivity.Have
Effect saves installing space, shortens the reaction time of instruction alarm.The knot of Hydraulic Field other products is can also be applied to simultaneously
Structure optimization, mitigate the direction such as weight, make that hydraulic system structure is compact, in light weight, integration degree is high.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Drawing explanation：1st, component is indicated, 2, little spring, 3, upper shell, 4, sensory package, 5, piston component, 6, spring, 7,
Lower house, 8, guide rod, 9, temperature-sensitive element.
Embodiment
Illustrate that embodiment of the invention is：Common heat-sensitive element is helical form, is placed in instruction chamber, with air
Contact；This new structure temperature-sensitive element is strip, is placed in fluid working chamber, can directly perceive oil temperature, makes temperature instruction.
As shown in figure 1, instruction component 1 is made up of magnet and protective cap, furtherly, magnet is by high-temp glue and protection
Cap is bonded, and instruction component 1 is assemblied in the upper end of the inner chamber of upper shell 3；The groove of assembling little spring 2 is machined with indicator assemblies 1；On
Housing 3 is connected by screw thread with hydraulic system；Sensory package 4 is made up of guide rod 8 and temperature-sensitive element 9, furtherly, temperature-sensitive element
9 are riveted on guide rod 8, and sensory package 4 is assemblied between upper shell 3 and lower house 7；Piston component 5 is by piston, sealing ring, guarantor
Guard ring forms, and furtherly, sealing ring and guard circle is cased with piston, piston component 5 is assemblied in the inner chamber lower end of upper shell 3, entered
One step is said, the groove of assembling spring 6 is machined with piston；Lower house 7 and upper shell 3 are connected through a screw thread.
During signalling means normal work, instruction component 1 and sensory package 4 is by together with magnetic attraction, and now signalling means is not
Alarm；Piston component 5 and sensory package 4 are Split type structure, and at high operating temperatures, temperature-sensitive element 9 expands in sensing housing 8
Chamber, temperature lock structure are in released state, piston component 5 and sensory package 4 are connected as a single entity, when signalling means pressure difference reaches report
During alert pressure difference, piston component 5 drives sensory package 4 to overcome the elastic force of spring 6 to depart from magnetic attraction to bottom offset, instruction component 1
And eject alarm；Under low-temperature condition, temperature-sensitive element 9 is contracted to sensing housing 8 inner chamber, and temperature lock structure is in locking shape
State, piston component 5 are separated with sensory package 4, even if signalling means pressure difference reaches alarm pressure difference, sensory package 4 is not also subjected to displacement,
Still it is attracting state.Such a temperature-sensitive element material is military products common used material, mainly makes temperature control, temperature-compensating, electric current limit
The elements such as system, temperature instruction, stable performance.
