Abstract
The utility model discloses an engine oil pressure alarm for a diesel engine. A main valve body is provided with a sliding valve type structured main valve stem, an induction block, a propulsion spring, and an adjusting device on the main valve stem; the vertical main valve stem sets a hand-operated bypass device, and is provided with a reed switch, a buzzer, and an alarm device to achieve alarm when the pressure of diesel engine lubricating oil is decreased and oil supply is deficient, and the diesel engine can be stopped automatically; the diesel engine can be force to start up by the hand-operated bypass device, so that safe operation is achieved under the conditions of not conducive to parking, and the aim of ship and vehicle protection is achieved. The utility model has warning function and automatic stop function, therefore, the bearing shell can be protected from burning even when the pressure of diesel engine lubricating oil is decreased and oil supply is deficient, and the utility model has long service life.
Description
The utility model relates to the diesel engine lubricating oil pressure warning unit.
Diesel engine must possess certain engine oil pressure in working order just can open the diesel oil passage, and after the diesel oil passage was closed in engine oil pressure decline, diesel engine caused burning out bearing shell because of stopping suddenly, and the thing of burning even happens occasionally.The alarm of prior art is electronic structure, be subject to humidity and influence working life, especially for the alarm on the ship, and the alarm of former technology only has warning device, can not automatic stopping, stop artificially,, perhaps can't hear at all and report to the police and burn out often because of the untimely bearing shell that makes burns.Also have a kind of automatic stop device that has, but the alarm free device, stopping device adopt ball-valve structure, often because of the too fast tool danger of stopping.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of energy self-stopping diesel engine lubricating oil pressure alarm, also can not burn out bearing shell under the operating mode low at the diesel engine oil pressure, that fuel feeding is not enough, long service life.
Embodiment of the present utility model: comprise main valve body and main valve stem, have diesel oil filler opening, diesel oil passage, diesel oil oil outlet, oil passageway on the main valve body.Main valve stem is a slide-valve structure, forming little Spielpassung with main valve body is connected, main valve stem is provided with that induction is fast, propelling spring and controlling device, main valve body is provided with the manual by-pass collar vertical with main valve stem, with be packaged with dry reed-pipe on the fixing induction valve body of main valve body, its lighting outlet connects external buzzer.
The utility model is compared with known technology; it not only has warning device but also have the automatic stopping function; therefore; even cross when engine oil pressure under the operating mode of low fuel feeding deficiency and also can not burn out bearing shell; it can adopt emergent by-pass collar after reporting to the police, and, goes back owing to adopt slide-valve structure to reach the purpose of protection boats and ships by the manual control by-pass collar; need not other sealing material in the mechanism, so long service life.

Describe in further detail by above-mentioned accompanying drawing embodiment.
The valve body of diesel engine lubricating oil pressure alarm (referring to Fig. 1-5) comprises by-pass valve body (16), main valve body (6) and induction valve body (13), connects one by screw.Main valve body (6) has diesel oil filler opening (5), diesel oil passage (4), diesel oil oil outlet (14), oil passageway (3), main valve stem (7) in the main valve body (6) is a slide-valve structure, the matching gap of it and main valve body (6) valve opening is 0.02-0.04mm, it does not adopt other sealing material, and the alarm life-span is prolonged.Main valve stem (7) is provided with the controlling mechanism of magnetic sensor block made of iron (8), propelling spring (9) and Regulation spring pressure, comprises the adjusting screw (11) and the locking nut (10) that are threaded with induction valve body (13).Induction valve body (13) is made of aluminium.
Main valve body (6) is provided with the manual by-pass collar vertical with main valve stem (7), this by-pass collar comprises by-pass valve body (16), handle (17), handle is connected with the overhanging end of bypass valve rod (2), bar is provided with bypass spring (1), the head of bypass valve rod is a sphere structure, can seal the diesel oil passage.When diesel engine is driven, manually operated valve must be the valve of opening, when alarm breaks down, opening the manually operated valve diesel engine can work as usual, this is to drop to can't drive the time when engine oil pressure, and crewman or driver must move for safety, can open manually operated valve and start diesel engine by force.
Induction valve body (13) is gone up has dry reed-pipe (12) with epoxy encapsulation, and dry reed-pipe hole to the centre distance of sensor block (8) is 14mm, guarantees that the interaction energy of sensor block makes dry reed-pipe generation alarm signal, but does not need high intensity magnetic field.The lighting outlet of dry reed-pipe connects to external buzzer.
Its dynamic structure is as follows:
When position (vertically) (see figure 2) that handle (17) is put out from the position (level) of closing, bypass valve rod (2) moves up, and opens bypass valve, makes diesel oil arrive oil outlet (14), diesel engine starting from filler opening (5) by bleed off circuit.
Behind the diesel engine starting, oil pump is started working simultaneously, produce pressure machine oil, pressure oil enters pressure chamber (15) by oil passageway (3), promotes main valve stem (7) compression propelling spring (9), when machine oil reaches certain pressure, spring is compressed fully, filler opening (5) and oil outlet (14) oil circuit are opened fully, closed bypass valve simultaneously, diesel engine proper functioning (see figure 3).
When engine oil pressure descends, because the active force of propelling spring (9) promotes main valve stem (7) and sensor block (8), inductor dry reed-pipe (12) is had an effect send signal, impel buzzer warning, asphalt channel reduces gradually simultaneously, fuel delivery reduces (see figure 4), and rotating speed is also along with slowing down.
When engine oil pressure continuation decline, propelling spring (9) continues to promote main valve stem (7), the diesel oil passage is closed fully, diesel engine automatic stopping (see figure 5).
The active force that the utility model is closed diesel oil passage spring can pass through adjusting screw (11) adjusting, locks with locking nut (10) then.
