A structure for mounting a battery pack device (20) on a vehicle has assembled battery cells mounted on the vehicle, accessories electrically connected to the assembled battery cells and using the cells, a battery case (21) for receiving the assembled battery cells, and an accessory case (31) for receiving the accessories. The battery case (21) and the accessory case (31) are arranged such that that portion (31s) of the accessory case (31) which is projected in the vertical direction is superposed on the battery case (21). The structure has excellent mountability.

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 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.

Disclosed is a cone crusher comprising a crusher cone that is retained on a driven eccentric bush that rotates about a journal (7) while being radially guided. The journal (7) is securely clamped in a journal holder (11) located in the lower housing part (8) and has a cylindrical upper supporting section (15) which is clamped, by means of an upper mechanical clamping device (14.1), in a bore forming the journal holder (11).
