Description
Technical field
The present invention relates to hydraulic transmission technology field, more particularly to a kind of integrated valve group of guide for carrying blocking sender.
Background technology
In the market engineering machinery pilot control integration module, because its installing space is narrow and small, structure is limited, nothing
Method installs the differential pressure transmitter device of filter, it is impossible to finds that filter core is blocked in time, causes filter bypass valve to be opened, do not filter
Fluid causes injury in system interior circulation to the element in system, result in the generation of failure.
The content of the invention
The purpose of the present invention is：
For above-mentioned the deficiencies in the prior art there is provided a kind of integrated valve group of guide for carrying blocking sender, it can be sent out in early stage
The blocking of existing filter core, and prompting changing filter core in time, so as to effectively reduce the failure of system, extend system lifetim.
The purpose of the present invention can be realized by following technical scheme：
It is a kind of carry block sender the integrated valve group of guide, include by filter, by-passing valve, check valve set into pilot valve
Block, in addition to accumulator, magnetic valve, differential pressure transmitter device on the outside of pilot valve block, pioneer pump carry out P mouthfuls of hydraulic fluid port with filtering
The PV mouths that device, check-valves, magnetic valve, fluid enter main valve pilot section are sequentially connected, and by-passing valve and differential pressure transmitter device difference are simultaneously
Connection is arranged on P2 mouthfuls of the import of filter between the outlet of filter, the PA mouths of differential pressure transmitter device and P mouthfuls, P2 mouthfuls of in parallel, pressures
The PB mouths of poor signalling generator are parallel to the outlet of filter, PS mouthfuls and accumulator, the oil inlet parallel connection, T mouthfuls, T2 mouthfuls respectively of magnetic valve
Oil return opening with magnetic valve is in parallel.
The magnetic valve quantity is at least one.
The signal that the differential pressure transmitter device is sent is for visual type or with output electric signal.
The beneficial effects of the present invention are：
A kind of integrated valve group sender of guide for carrying blocking sender of the present invention in time, is effectively reduced the system failure, extension system
The life-span of system；System perfecting, further increases the reliability of system.A kind of guide for carrying blocking sender of the present invention is integrated
Valve group principle is simple, can realize standardized production with producing in serial form；Compact conformation, reduces installing space, and saving is manufactured into
This.
Brief description of the drawings
Fig. 1 is schematic diagram of the invention；
Fig. 2 is the front view of embodiments of the invention 1；
Fig. 3 is the left view of embodiments of the invention 1.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides it is a kind of carry block sender the integrated valve group of guide, include by filter 1,
The pilot valve block 2 that by-passing valve 3, check-valves 4 are constituted, in addition to the accumulator 5 installed in the outside of pilot valve block 2, magnetic valve 6, pressure
Poor signalling generator 7.Pioneer pump carrys out the PV mouths that P mouthfuls of hydraulic fluid port enters main valve pilot section with filter 1, check-valves 4, magnetic valve 6, fluid
It is sequentially connected, the quantity of magnetic valve 6 is at least one, can be one or more.By-passing valve 3 and differential pressure transmitter device 7 are distinguished
P2 mouthfuls of the import in filter 1 is installed in parallel between the outlet of filter 1, the PA mouths of differential pressure transmitter device 7 and P mouthfuls, P2 mouthfuls simultaneously
Connection, the PB mouths of differential pressure transmitter device 7 are parallel to the outlet of filter 1, and PS mouthfuls and accumulator 5, the oil inlet of magnetic valve 6 are distinguished simultaneously
Connection, the oil return opening parallel connection of T mouthful, T2 mouthfuls and magnetic valve 6.The signal that the differential pressure transmitter device 7 is sent is visual type or electric with output
Signal.
Embodiment 1：Fig. 2, Fig. 3 show one embodiment of the present of invention, and the wherein quantity of magnetic valve 6 is one.
The a kind of of the present invention carries the guide oil edge for blocking the integrated valve group of guide of sender suitable for mini-excavator main valve.
The present invention operation principle be, pioneer pump（Embodied not in figure）The fluid pumped out carrys out P mouthfuls of hydraulic fluid port by pioneer pump and enters filtering
Device 1, by check-valves 4 after being filtered through filter 1, into accumulator 5 and the oil inlet of magnetic valve 6, after magnetic valve 6 is powered,
Fluid enters the pilot section of main valve by PV mouthfuls（Embodied not in figure）, so that main valve can be acted further.Work as filtering
Device 1 is blocked, and when its import and export pressure difference is more than 3 default Opening pressure of by-passing valve, by-passing valve 3 is opened, it is ensured that pioneer pump is pumped out
Oil continue transported to main valve arrive first part.When the inlet outlet pressure differential of filter 1 exceedes the setting value of differential pressure transmitter device 7,
Differential pressure transmitter device 7 sender, reminds user to change filter core in time, it is to avoid injury of the dirty oil to each element in system.
Although the present invention is described and illustrated here by some or some particular arrangements, but its purpose and limit is not lain in
The details is made, because may have various modifications and structure change in the range of patent requirements, without departing from spirit.
The present invention relates to part is same as the prior art or can be realized using prior art.
