Abstract

A vent valve is composed of a vent valve seat, an oil discharge steel ball and a guard plate, wherein the two side inner walls in the vent valve seat and near the oil discharge hole are cone surfaces which are inclined inwards, the inner walls near the guard plate are vertical with the guard plate, and the oil discharge steel ball is sealed inside by the vent valve seat and the guard plate. The utility model has simple structure, easy manufacture, low cost, high reliability, long service life and wide application in vehicle hydraulic system.

Description

Draining valve
Technical field
The utility model relates to a kind of draining valve, belongs to the hydraulics field.
Background technique
The most draining valve that uses of automobile is made up of oil extraction valve seat, oil extraction steel ball, catch, spring and five parts of spring seat at present, the inwall of oil extraction valve seat is vertical with catch, spring is installed on the oil extraction valve seat, and a spring seat has all been installed at its two ends, when the oil extraction steel ball is subjected to oil cylinder working-pressure, oil extraction steel ball holddown spring, oil drainage hole is stopped up, when the oil extraction steel ball no longer bears the pressure of oil cylinder, because spring has stretchability, thus oil extraction steel ball pop into position is put, at this moment, oil drainage hole is opened, and in-oil cylinder oil is discharged.Though this device reaches the purpose of oil extraction to a certain extent,, the cost of this device is also higher relatively, therefore, designs a kind of high-performance, draining valve becomes actual required cheaply.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of be widely used in car hydraulics, simple in structure, easy processing, with low cost, reliability is high, the draining valve of long service life.
The technical solution adopted in the utility model is: this draining valve is made up of oil extraction valve seat, oil extraction steel ball, catch, the inner both sides inwall near oil drainage hole of oil extraction valve seat is taper, and the gradient of conical surface is inside, and vertical with catch near the inwall of catch, the oil extraction steel ball is locked in its inside by oil extraction valve seat and washer.
Draining valve of the present utility model is widely used in car hydraulics, be installed in the forward gears oil cylinder, when carrying out gear switch, can fast the in-oil cylinder oil of forward gears be discharged,, guarantee automobile normal running to guarantee that vehicle can carry out gear switch smoothly.
Be under the state that runs up at the input shaft component, adjust the forward gears oil cylinder when hydrovalve and be in when pressure condition is arranged, when promptly being full of oil in the oil cylinder, the oil extraction steel ball is inwardly pushed under the effect of oil pressure gradually, thereby oil drainage hole is stopped up.
Under identical state, when hydrovalve adjusting oil cylinder was in the zero-pressure state, the oil pressure that acts on the oil extraction steel ball also disappeared thereupon.At this moment, the oil extraction steel ball still along with the input shaft component at high speed rotating, under action of centrifugal force, the oil extraction steel ball tightly is pressed on the conical surface of oil extraction valve seat, the conical surface is when being subjected to the active force that the oil extraction steel ball gives, also provide a reaction force to the oil extraction steel ball, the oil extraction steel ball is under the effect of this reaction force, and beginning is moved in oil cylinder, so, oil drainage hole is opened, and in-oil cylinder oil is discharged rapidly, flows to gearbox.
Owing to adopt such scheme, cancelled spring assembly, on the basis of improving reliability, at the cost that does not have to have reduced under the situation of mechanical wear automotive transmission.Thereby it is simple in structure that the utility model has been accomplished, easy processing is with low cost, and reliability height, and long service life can be widely used in car hydraulics.
