Background technique
Hydraulic services differential pressure signaling type differential pressure transmitter device is mainly used in in-line filter.In the time of hydraulic work system, the filter core in filter is imported and exported and is listened pressure to produce pressure reduction because the pollutant in intercepting system stops up gradually.In the time that pressure difference increases to signal-transmitting machine setting, signal-transmitting machine sends signal automatically, and indication mechanism operator should clean or renew cartridge more, gram insurance system safe operation.Sender is sent out switch form the obstruction of oil purifier is reported to the police, or cuts off the control circuit relevant to hydraulic system with switch form, thus the safety of protective system.Work as hydraulic work system, the pollutant in fluid is constantly tackled by filter core in oil return circulation, and the inlet pressure of return filter is increased gradually, in the time that pressure increases to the setting of signal-transmitting machine, and signal-transmitting machine action.And connecting tutorial light or buzzer warning with switch form, indication people should clean or renew cartridge or cut off the control circuit relevant to hydraulic system with switch form more in time, to guarantee that hydraulic system normally moves.
summary of the invention
In order to overcome deficiency and the defect in background technique, the utility model provides a kind of filter pressure differential pressure transmitter device, solve existing differential pressure transmitter device in the time regulating pressure difference, thereby because the less stable of adjusting part causes the lower problem that affects product usability of degree of regulation.
The technical solution of the utility model is: a kind of filter pressure differential pressure transmitter device, comprise housing, sliding assembly and sensitive switch, described sensitive switch is provided with control iron plate, described housing is provided with cavity, described sliding assembly is located in cavity and is divided into oil suction chamber and goes out oil pocket, described sliding assembly comprises the slide core that is positioned at oil pocket end, magnetic part, elastic component and be positioned at the adjustable lever of oil suction chamber end, described magnetic part is located in slide core and with the control iron plate magnetic of sensitive switch and is coordinated, described elastic component is installed on the end of slide core, described adjustable lever axially can regulate and be connected in slide core, on described adjustable lever, locking body is installed, described locking body and slide core clamping matching form adjustable lever and coordinate with slide core axial limiting.
Described adjustable lever is threaded with slide core, and described locking body is threaded with adjustable lever and is inconsistent with the end face of slide core.
Further, described slide core is provided with groove, and described adjustable lever is threadedly connected on the inwall of groove, between the lower end of described adjustable lever and the bottom of groove, is provided with spring.
Further, described magnetic part is cylinder-shaped magnet.
Further, described locking body is nut.
The beneficial effects of the utility model: adjusting part is carried out to locking because this filter pressure differential pressure transmitter device adopts locking body, effectively prevent that adjusting part from reducing because slip causes stability after adjusting, thereby make the degree of regulation of pressure difference reduce the use that affects product.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure, housing 1, sensitive switch 2, controls iron plate 3, cavity 4, oil suction chamber 5, goes out oil pocket 6, slide core 7, magnetic part 8, elastic component 9, adjustable lever 10, locking body 11, groove 12, spring 13.
Embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, a kind of filter pressure differential pressure transmitter device, comprise housing 1, sliding assembly and sensitive switch 2, described sensitive switch 2 is provided with controls iron plate 3, described housing 1 is provided with cavity 4, described sliding assembly is located in cavity 4 and is divided into oil suction chamber 5 and goes out oil pocket 6, described sliding assembly comprises the slide core 7 that is positioned at oil pocket end, magnetic part 8, elastic component 9 and be positioned at the adjustable lever 10 of oil suction chamber end, described magnetic part 8 is located in slide core 7 and with control iron plate 3 magnetic of sensitive switch 2 and is coordinated, described elastic component 9 is installed on the end of slide core 7, it is characterized in that: described adjustable lever 10 axially can regulate and be connected in slide core 7, on described adjustable lever 10, locking body 11 is installed, described magnetic part 8 is cylinder-shaped magnet, described locking body 11 is nut, described locking body 11 and slide core 7 clamping matching form adjustable lever 10 and coordinate with slide core 7 axial limitings.When use, according to pressure difference need to mobile adjustable lever 10, axial length between adjustable lever 10 and slide core 7 can be regulated, when hydraulic medium enters from oil suction chamber 5, when pressure increases gradually, adjustable lever 10 is pressed on liquid top, make adjustable lever 10 drive slide core 7 to move axially, because slide core 7 is provided with magnetic part 8, thereby make magnetic part 8 and the control iron plate 3 phase adhesives on sensitive switch 2 touch switch open alarms, simultaneously, slide core 7 drive elastic component 9 and the housing of sensitive switch 2 push up mutually press make elastic component 9 compressed, while regulating pressure difference, move axially the length that adjustable lever is positioned at slide core 7, and match to realize locking by locking body with slide core 7, because this filter pressure differential pressure transmitter device adopts locking body, adjusting part is carried out to locking, effectively prevent that adjusting part from reducing because slip causes stability after adjusting, thereby make the degree of regulation of pressure difference reduce the use that affects product.
