Abstract
The utility model discloses a power station duplex filter bypass device, which comprises a duplex filter, an inlet pipeline and an outlet pipeline, wherein the inlet pipeline and an inlet of the duplex filter are connected, the outlet pipeline is connected with an outlet of the duplex filter, the inlet pipeline is connected with an inlet tee, an inlet ball valve is arranged on the inlet channel which is arranged between the inlet tee and the duplex filter, the outlet channel is connected with an outlet tee, and an outlet ball valve is arranged on the outlet pipeline which is connected between the outlet tee and the duplex filter. The power station duplex filter bypass device has the advantages that the power station duplex filter bypass device completely achieve to change blocked filters without shutting down main equipment and systems, guarantees the main equipment and the systems to safely and reliably run for long period, is more economical compare to directly change a two-position six-way switch valve, is once and for all, and is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of shunting device that is convenient for changing filter element, particularly relates to a kind of power oil station duplex filter shunting device.
Background technique
Need ensure hydraulic power or lubricated equipment and system by oil system endlessly, all must use petrol station, clean (particle) degree of fluid is required simultaneously also higher, so must install oil filtering device additional in oil system.Because machinery, equipment need long-term operation not stop transport at any time, the filter core of oil filtering device also must regularly replace, and just requires a set of operation, ensures a set of for subsequent use reliably simultaneously.Like this leakproofness of two six-way valves is proposed to requirements at the higher level, but in actual meeting the tendency, because the interior leakage of two six-way valves of various factors exists all the time.
The duplex filter of existing power oil station is made up of two monotubular filters and two six-way transfer valves.Be to make oil system in the situation that not stopping transport main equipment and system, can change stifled filter core by switching two six-way transfer valves in theory, the system fluid of keeping can not interrupt.But in actual meeting the tendency, because two six-way transfer valves are along with the more increase of renew cartridge switching frequency, its sealability, declining, causes interior leakage in various degree, and making to change filter core for subsequent use online can not realize.Main equipment and the system of can only stopping transport could be changed stifled filter core, has a strong impact on like this system long period safety, reliable operation.
Model utility content
The purpose of this utility model is to provide a kind of power oil station duplex filter shunting device.
The purpose of this utility model is implemented by following technological scheme, a kind of power oil station duplex filter shunting device, it comprises duplex filter, inlet pipe and outlet conduit, described inlet pipe is connected with the entrance of described duplex filter, described outlet conduit is connected with the outlet of described duplex filter, on described inlet pipe, be connected with entrance threeway, the described inlet pipe connecting between described entrance threeway and described duplex filter is provided with entrance ball valve, on described outlet conduit, be connected with outlet threeway, the described outlet conduit connecting between described outlet threeway and described duplex filter is provided with outlet ball valve, described entrance threeway is connected by bypass duct with described outlet threeway, described bypass duct is provided with bypass ball valve.
Under runnability, entrance ball valve and outlet ball valve are opening state, and bypass ball valve is closed condition.Only, in the time of replacing stifled filter core, even if two six-way transfer valve leakage currents are large again, the bypass ball valve that duplex filter is exported between threeway and entrance threeway is opened, and has just realized the short circuit of oil system.Close duplex filter entrance ball valve and export ball valve and just can effectively isolate duplex filter, realized online more renew cartridge.After stifled filter element replacing, make fluid recover original system trend by above-mentioned opposite approach operation.The fluid short time is not walked filter screen and can not cause harmful effect to the hydraulic pressure of capital equipment and system, lubrication system.
The utility model has the advantage of, realized do not need stop transport main equipment and system completely by the utility model, with regard to replaceable stifled filter core.Long period safety, the reliable operation of capital equipment and system are ensured; Than directly changing the many of two six direction changeover valve economy, and put things right once and for all.Simple in structure, easy to operate.
