Abstract
The utility model relates to a pressure type oil filter, in particular to an oil filling and discharging reversing device of the pressure type oil filter. The reversing device comprises the pressure type oil filter as well as an oil filling pipe and an oil discharging pipe which are installed on an oil inlet and an oil outlet of the pressure type oil filter. The device is characterized in that a valve I is installed on the oil filling pipe, and a valve II is installed on the oil discharging pipe; two branch pipelines are respectively installed on the oil filling pipe and the oil discharging pipe, and a valve is installed on each branch pipeline, wherein one end of a branch pipeline I is communicated with the pipeline of the oil outlet of the valve I, and the other end thereof is communicated with the pipeline of the oil outlet of the valve II; one end of the branch pipeline II is communicated with the pipeline of the oil inlet of the valve I, and the other end thereof is communicated with the pipeline of the oil inlet of the valve II. By the improvement of the proposal, after the one-step installation, the conversion of the oil inlet and the oil outlet of the pressure type oil filter can be realized by opening and closing four valves, and the phenomenon of oil spray, oil seepage and oil leakage caused by twice disassembly and assembly is avoided. Therefore, the device has the characteristics that the structure is reasonable, the using is convenient and the like.
Description
Technical field
The utility model relates to the pressure type oil filter, and particularly the pressure type oil filter passes in and out oily reversing arrangement.
Background technology
In the Repair of Transformer operation process, usually working pressure formula oil filter is handled the oil in the transformer, must be in processing procedure by switching into and out of the oil pipe flow process of finishing the work, and each operation needs artificial 3 people, average operating time is about 12 minutes, increased staff's workload, reduced operating efficiency, switching in the process of oil pipe simultaneously, usually be accompanied by the phenomenon of oil spout, oil impregnate, leakage of oil, cause the waste of oil on the one hand, the scene is dyed by greasy dirt, cause environmental pollution.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of pass by conversion valve is provided and closes, and just can realize the reversing arrangement of pressure type oil filter into and out of the conversion of hydraulic fluid port.
For achieving the above object, the technical solution of the utility model is: a kind of pressure type oil filter passes in and out oily reversing arrangement, comprise the pressure type oil filter and be installed in the pressure type oil filter, advancing on the oil-out, flowline, it is characterized in that on oil inlet pipe, being equipped with valve I, valve II is installed on flowline, on oil inlet pipe and flowline, be separately installed with two bye-passes, valve all is installed on each bye-pass, wherein the end of bye-pass I is connected with the pipeline of the oil-out of valve I, the other end is connected with the pipeline of valve II oil-out, the end of bye-pass II is connected with the pipeline of the oil-in of valve I, and the other end is connected with the pipeline of valve II oil-in.
Above-mentioned valve can be ball valve or magnetic valve.
The utility model is the improvement that the connecting line that has the pressure type oil filter now is carried out, improvement by this programme, can be after once mounting, can be by the keying of four valves, realize of the conversion of pressure type oil filter, the phenomenon of the oil spout of having avoided bringing, oil impregnate, leakage of oil by twice dismounting into and out of hydraulic fluid port.This device has characteristics such as rational in infrastructure, easy to use.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present utility model.
The specific embodiment
As shown in Figure 1, on the oil inlet pipe 9 of pressure type oil filter 1, valve I8 is installed, on the flowline 2 of pressure type oil filter, valve II4 is installed, on oil inlet pipe and flowline, intersect respectively two bye-passes are installed, wherein the upper end of bye-pass I5 is connected with the pipeline of valve I8 oil-out, the lower end is connected with the pipeline of valve II4 oil-out, and the lower end of bye-pass II7 is connected with the pipeline of the oil-in of valve I8, and the upper end is connected with the pipeline of valve II4 oil-in.Valve III6 is installed on bye-pass I5, valve IV3 is installed on bye-pass II7.During use, with oil inlet pipe 9 and flowline 2 in accordance with regulations mode connect, Open valve I8, valve II4, valve-off IV3, valve III6, at this moment oil just enters the pressure type oil filter along oil inlet pipe, by flowline 2 discharges.When the needs oil inlet and outlet commutates, Open valve IV3, valve III6, valve-off I8, valve II4 have just finished the commutation of oil inlet and outlet.Above-mentioned valve can be ball valve or magnetic valve.When adopting magnetic valve, the control corresponding system is just arranged.
Claims (2)
1, a kind of pressure type oil filter passes in and out oily reversing arrangement, comprise the pressure type oil filter and be installed in the pressure type oil filter, advancing on the oil-out, flowline, it is characterized in that on oil inlet pipe (9), being equipped with valve I (8), valve II (4) is installed on flowline (2), on oil inlet pipe and flowline, be separately installed with two bye-passes, valve all is installed on each bye-pass, wherein the end of bye-pass I (5) is connected with the pipeline of the oil-out of valve I (8), the other end is connected with the pipeline of valve II (4) oil-out, the end of bye-pass II (7) is connected with the pipeline of the oil-in of valve I (8), and the other end is connected with the pipeline of valve II (4) oil-in.
