The invention discloses a closed type recycle washing device for a pipeline of a hydraulic system. The closed type recycle washing device comprises an oil washing pipe (1), an oil return pipe (2), a to-be-washed system (16), motors (5) and oil pumps (6); the oil washing pipe (1) is provided with the oil pumps (6) which is driven by the motors (5), the output ends of the oil pumps (6) are sequentially connected with pressure gages (7), a ball valve (8), filters (9), a ball valve (10) and a ball valve (11); the ball valve (11) is connected with one end of the to-be-washed system (16) through oil-resistant rubber hoses (12); the oil return pipe (2) sequentially passes through a ball valve (13), a ball valve (14), the filters (9), the pressure gages (7), an air cooler (15) and a ball valve (3) to be communicated with the input ends of the oil pumps (6); the ball valve (3) and the ball valve (10) are arranged on the side face of the oil washing pipe (1), and the ball valve (14) is arranged on the side face of the oil return pipe (2). The closed type recycle washing device has the advantages that the oil capacity used for washing is saved, the oil washing time is saved, the oil washing efficiency is improved, the on-site arrangement and conveying are convenient, the structure is simple, and the cost is saved.

An apparatus for detecting start-up of a vehicle and for controlling an external device includes a detecting unit and a control unit. The detecting unit is to be electrically connected to a battery of the vehicle for obtaining information associated with a voltage of the battery. The control unit is electrically connected between the detecting unit and the external device, and is configured to determine whether the vehicle has started up with reference to the information obtained by the detecting unit, and to generate a working signal for triggering the external device upon detecting that the vehicle has started up.

The invention discloses a balance valve with a quickly-closing valve plug. The front side and the rear side of a valve bush shell surface are respectively provided with a first main oil port and a second main oil port; the middle of a valve bush is provided with a through hole in sliding fit with the main valve plug; two ends of the through hole are respectively sealed and assembled with a front end cover and a rear end cover; the front end and the rear end of the middle of a main valve plug are respectively assembled with a main check valve assembly and a quickly-closing check valve assembly; the quickly-closing check valve assembly comprises a check valve and a throttle valve which are arranged in parallel, wherein a free flowing-in end of the check valve is communicated with the secondmain oil port; the front end cover is provided with an outer control port which controls the main valve plug to slide and operate backwards; the valve bush, the main valve plug, each check valve, thethrottle valve and the like which are in an internal and external matching and sliding structure are adopted, integral design is reasonable, and structure is compact; the check valve structure is simultaneously embedded in a rear cavity of the main valve plug, so that sinking distance when a hydraulic cylinder retracts during practical operation can be effectively reduced, and the structure is simple; and when the valve is operated to open, the stability of integral operation is guaranteed when the main valve plug automatically resets, and thus the balance valve has the advantages of reliabledesign and long service life.

The invention discloses a frame type curtain wall stand column and cross beam fast-connecting system which comprises a stand column body, a left cross beam body and a right cross beam body. A first connecting plate and a second connecting plate are arranged at the tail ends of the left cross beam body and the right cross beam body; grooves paired with the first connecting plate and the second connecting plate are formed in the stand column body; a splicing part is arranged on the first connecting plate; a splicing groove paired with the splicing part is formed in the second connecting plate; the tail ends of the first connecting plate and the second connecting plate are connected through the splicing part and the splicing groove; a first tenon is arranged on the left cross beam body; a second tenon is arranged on the back face of the second connecting plate; and a first mortise paired with the first tenon and a second mortise paired with the second tenon are arranged on the stand column body. The frame type curtain wall stand column and cross beam fast-connecting system is simple in installation structure and fast in installation speed.

The invention discloses a multifunctional wet gas pipeline top corrosion automatic simulation test device, which is composed of a test loop system, a control and display system, and the test loop system includes: a gas cylinder, a deposition tank, an electric heater, a fixed pipe, a flexible Composite tubes, test tubes, electrodes, temperature probes, pressure probes, etc. The test tubes are rectangular square tubes, with gas injection ports and multiple reference electrode installation holes reserved on the bottom surface, and liquid injection ports and exhaust gas ports reserved on the top surface. There are multiple sample mounting holes, multiple working electrode mounting holes and probe mounting holes, auxiliary electrode mounting holes are reserved on the side, and the two ends of the test tube are respectively connected to a flexible composite tube through flanges. The benefit of the present invention is that the device can not only reflect the corrosion situation of the top of the wet gas pipeline laid at 0-90° in the oil and gas development process, but also evaluate the effectiveness of the corrosion inhibitor under this working condition and the effect of the corrosion inhibitor on the The corrosion reduction effect of the partially damaged part of the coating.
