Description
Technical field:
The utility model relates to the I. C. engine oil pressure control device, particularly a kind of I. C. engine oil pressure protective device that can stop fuel supply when the I. C. engine oil underpressure automatically.
Background technique:
As everyone knows; during internal combustion engine; when engine oil pressure is lower than the pressure of regulation; be easy to cause the ablation of bent axle and bearing shell; on the internal-combustion engine fuel level indicator is installed all now; what have also is equipped with the engine oil pressure alarm; fuel level indicator and alarm are by sensor; composition such as relay and electronic circuit; during internal combustion engine; when engine oil pressure is lower than specified value; fuel level indicator will show; alarm gives the alarm and reminds operator's shutdown or add machine oil to internal-combustion engine; fuel level indicator and alarm can only show engine oil pressure and remind operator; can not realize autostop; it is untimely slightly to shut down; the ablation of bent axle and bearing shell still can appear; cause mechanical failure; I had once invented a kind of " internal-combustion engine automatic safety device "; the patent No. is 912117591; it is by valve body; plunger; pull bar; spring; plug and the oil pipe union that is connected with valve body are formed; wherein; plunger is located in the middle of the valve body; one end and pull bar, the other end is provided with step, and an oil inlet hole that is provided with valve body is established in the centre; the through hole that oil outlet communicates and answers; fuel path is unimpeded during with assurance internal-combustion engine proper functioning; spring housing is located on the pull bar, and an end is connected with plug, and the other end contacts with plunger; plug is connected with valve body by screw thread; in order to adjust the pressure of spring to plunger, make it and the I. C. engine oil pressure stipulated adapts, the deficiency of this device be install inconvenient.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of I. C. engine oil pressure protective device of simple in structure, easy for installation, reliable operation is provided.
The utility model can reach by following measure:
A kind of I. C. engine oil pressure protective device; comprise valve body; plunger; mast; spring; and the oil pipe union that is connected with valve body is formed; it is characterized in that valve body is provided with the pulling shaft hole; pulling shaft one end is provided with the spring catch platform; the other end is provided with draw ring; being with spring on the pulling shaft is installed in the pulling shaft hole through helping pull a cart; help pull a cart and be provided with sliding sleeve; sliding sleeve is connected with adjustment sleeve through pole; adjustment sleeve is fixed on the mast through adjusting nut and setscrew nut; the machine that colludes is connected with helping pull a cart through bearing pin, connects to put to be provided with the groove that matches with the machine control arm of colluding, and pulling shaft is provided with and colludes machine and carries out the pin rod that arm matches.
The said plunger of the utility model is to be provided with block plate and to be connected with the oil resistant leather cup and to form by being located at the mast end, and the move left and right with according to the pressure control mast of I. C. engine oil realizes the protection of I. C. engine oil pressure.
The utility model can be installed in any place of I. C. engine oil pipe, when I. C. engine oil pressure is lower than the pressure of regulation, can automatically force the internal-combustion engine shutdown,, have advantages such as simple in structure, easy for installation, reliable operation with ablation and other fault of avoiding I. C. engine crankshaft and bearing shell.
