Abstract
The utility model relates to an internal-combustion engine exhaust control valve, the air pump formula braking system has been adopted in the air brake of current tractor, large and medium-sized car, engineering vehicle and trailer. The exhaust control valve of the internal combustion engine can replace an air pump, an air reservoir, a brake valve and the like. The exhaust gas discharged by internal combustion engine is used as gas source to implement vehicle brake and lift of suspended agricultural implement, and its structure is simple, operation is reliable, maintenance is convenient, power consumption is not reduced, and its cost is low, so that it is an ideal control valve.
Description
The utility model relates to particularly I. C. engine exhaust control valve of control valve.
The air braking of existing tractor, big-and-middle-sized automobile, engineering vehicle and trailer all adopts the air pump type braking system, needs configuration air pump, gas receiver, brake valve etc., its complex structure, easy break-down, maintenance difficult, consumed power, cost height.
It is the I. C. engine exhaust control valve of source of the gas that the purpose of this utility model is to provide a kind of waste gas of discharging during with internal combustion engine, replace air pump, gas receiver, brake valve in the existing vehicle air braking system, realize the braking of tractor, big-and-middle-sized automobile, engineering vehicle and trailer, and can realize that tractor hangs the lifting of farm implements.
Accompanying drawing is structure of the present utility model (analysing and observe) figure.
Valve seat 1 and the valve of the exhaust gas control valve for IC engine that the utility model provides Body 6 links to each other, and the left side of valve seat 1 links to each other with internal-combustion engine vent-pipe, valve body 6 The upper end link to each other with silencer. When Vehicle Driving Cycle, handle main valve shift fork 8 Be in shown position, the waste gas that internal combustion engine is discharged enters valve seat 1 by blast pipe, Enter valve body 6 through valve seat 1 and valve body 6 in conjunction with the through hole on right side, face place again, Again from valve body 6 upper ends outside silencer discharge machine.
The right-hand member of main valve shift fork 8 is installed in the groove of main valve 7.Main valve 7 is installed in the valve body 6.Secondary valve 9 is installed in the main valve 7, and the upper end heads on main valve shift fork 8, and the lower end heads on the conduit 10 that is installed in unidirectional valve seat 11.Unidirectional valve seat 11 is installed on the valve seat 1.Conduit 10 upper ends are for sealing, and the lower ending opening place heads on one-way valve 12.Radial direction through hole is arranged at conduit 10 tops, and there is radially groove the lower end.One-way valve 12 is supported on the check valve spring 13, and check valve spring 13 is supported on the unidirectional valve pocket 14 that is connected with unidirectional valve seat 11.Handle main valve shift fork 8 and be rotated counterclockwise by shown position, then its right-hand member rotates and drives main valve 7 and rises to and close the through hole that the right side is located on valve seat 1 and valve body 6 mating faces in the groove of main valve 7, secondary valve 9 of while, conduit 10, one-way valve 12 also with on move.At this moment, the exhaust that enters valve seat 1 is entered conduit 10 and is washed open one-way valve 12 by the radial direction through hole of conduit 10 and enters unidirectional valve pocket 14, enter the gas pipeline that communicates with unidirectional valve pocket 14 again and enter the air chamber of motor vehicle braking system or the cylinder of suspension farm implements elevating system, realize the lifting of vehicle braked or farm implements when air pressure sharply rises to rating value.
Bypass valve shift fork 3 is contained on the bypass valve 2, and tappet 4 is equipped with in bypass valve 2 upper ends, and case of by-pass valve 5 is equipped with in tappet 4 upper ends, and tappet 4 and case of by-pass valve 5 are installed in the valve body 6.When the air pressure in the valve seat 1 is no more than limit value, the through hole in the left side, junction plane place of the lower end closed valve seat 1 of bypass 2 and valve body 6.When the air pressure in the valve seat 1 surpassed limit value, bypass valve 2 was backed down in exhaust, enters valve body 6 and excrete from the through hole in valve seat 1 and valve body 6 junction planes left side; When valve body 1 internal air pressure dropped to limit value, by the effect of case of by-pass valve 5, bypass valve 2 fell to cutting out again the through hole in valve seat 1 and left side, valve body 6 junction plane places, thereby had guaranteed the proper functioning of internal-combustion engine.
Handle main valve shift fork 8 and go to shown position do dextrorotation, then drive main valve 7 and move down, valve seat 1 is open with the through hole on right side, valve body 6 junction plane place, and exhaust enters valve body 6 by valve seat 1 and excretes.Secondary valve 9 moves down with the rotation of main valve shift fork 8, and conduit 10 also moves down.Valve seat 1 internal air pressure sharply reduces, and one-way valve 12 rises under the effect of check valve spring 13 and withstands conduit 10 end openings.Gas in the air chamber of braking system or the cylinder of suspension system returns into unidirectional valve pocket 14 through gas pipeline, radially groove through conduit 10 lower ends enters conduit 10, and enter valve seat 1 from the radial direction through hole on conduit 10 tops, excrete through valve body 6 again, then air pressure sharply reduces in the cylinder of the air chamber of braking system or suspension system, has realized stopping braking and has recovered vehicle driving or farm implements whereabouts.
In the vehicle driving up braking state and when simultaneously internal-combustion engine was in flameout state, vehicle was then handled bypass valve shift fork 3 earlier if will start to walk, and makes and carries on the bypass valve 2, pilots engine then.After the motor proper functioning, handle main valve shift fork 8 again and turn clockwise, then the air pressure of the air chamber of braking system sharply reduces, and realizes stopping braking and recovers vehicle driving.Treat to handle bypass valve shift fork 3 behind the vehicle start, bypass valve 2 is fallen to close the through hole in valve seat 1 and left side, valve body 6 junction plane places, but just cruising of vehicle then.
The I. C. engine exhaust control valve that the utility model provides is simple in structure, use is reliable, and is easy to maintenance, not consumed power, cheap, be a kind of ideal control valve that is used to realize tractor, big-and-middle-sized automobile, engineering vehicle and trailer braking protection valve and the lifting of tractor suspension farm implements.
