Abstract
The utility model provides an automobile exhaust valve on a motor automobile, which comprises a valve body and an exhaust screw which is connected with the valve body by threads. A positioning rod is arranged at the front end of the exhaust screw. A spring is sheathed on the positioning rod. A metal sealing ball is arranged in the valve body. The spring acts on the metal sealing ball. The side part of the valve body is also provided with an exhaust port. In general, the automobile exhaust valve is arranged on an oil way of an automobile division pump or a clutch division pump. When the oil way is exhausted, only one person can operate; the operation is convenient, and air in the oil way can be thoroughly exhausted.
Description
The utility model relates on a kind of Motor Vehicle, particularly the venting gas appliance that uses on Motor Vehicle brake cylinder and the clutch slave cylinder.
Break on the Motor Vehicle or clutch generally adopt hydraulic transmission.Hydraulic transmission requires the thorough emptying of air on the hydraulic pipe line, to guarantee the vehicle safety operation.After the new installation of pipeline or maintenance of break or clutch, must carry out bleeding.Bleeding generally is such: jam on break or clutch pedal several continuously and keep motionless, unclamp outlet valve, tighten after exhaust.For several times, will tighten outlet valve after the thorough emptying of the gas in the oil circuit so repeatedly.In this course, because brake pedal is positioned at car, and outlet valve generally is positioned at the vehicle chassis place, therefore must two people cooperate the ability complete operation.This is cumbersome when practical operation, and the situation that gas does not have emptying may occur.
The purpose of this utility model provides a kind of simple in structure, the one man operation and the thorough Automobile exhaust valve of emptying gas.
This Automobile exhaust valve comprises valve body and exhaust bolt, and exhaust bolt connects with valve body by screw thread, and the exhaust bolt front end is provided with positioning rod, socket spring on the positioning rod, the metallic seal ball is set in the valve body, and spring action is on the metallic seal ball, and the sidepiece of valve body also is provided with exhaust port.This Automobile exhaust valve generally is installed on the oil circuit of automobile brake wheel cylinder or clutch slave cylinder.When oil circuit normally used, the positioning rod roof pressure of exhaust bolt front end contacted the interior sealing surface of metallic seal ball and valve body on the metallic seal ball, guarantees that this outlet valve can not leak.In the time of need carrying out bleeding, as long as exhaust bolt is outwards withdrawed from sub-fraction, metallic seal this moment ball still contacts with sealing surface in the valve body under the effect of spring; Jam on brake petal then, give the oil circuit supercharging.Because the elastic force of spring action on the metallic seal ball is limited, when the gas pressure in the oil circuit during greater than the elastic force of spring, gas will discharge by the metallic seal ball naturally.Carry out aforesaid operations several times repeatedly, can be with the gas emptying in the oil circuit.At last, as long as exhaust bolt is tightened.
Compared with prior art, the Automobile exhaust valve that the utility model provides can singlely be operated, and is easy to use; Owing to adopt spring to push down the structure of metallic seal ball in the valve body, can prevent gas backstreaming, the gas in the thorough emptying oil circuit of energy.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the schematic representation of Automobile exhaust valve when carrying out bleeding that the utility model provides.
Fig. 2 is the schematic representation of Automobile exhaust valve when oil circuit normally uses that the utility model provides.
Among the figure, 1, valve body; 2, exhaust bolt; 3, positioning rod; 4, spring; 5, metallic seal ball; 6, exhaust port; 7, sealing surface.
As shown in Figure 1, this Automobile exhaust valve is made up of valve body 1, exhaust bolt 2, spring 4 and metallic seal ball 5.Valve body 1 is connected on the oil circuit of brake cylinder or clutch slave cylinder, and communicates with oil circuit.The endoporus aperture on valve body 1 top is greater than the bottom, and upper inner is provided with internal thread.Exhaust bolt 2 connects with valve body 1 by screw thread.The positioning rod 3 of exhaust bolt 2 front ends is cylindric, and external diameter is less, is positioned on the central axis of exhaust bolt 2, and is connected as a single entity with exhaust bolt 2.There is a conical sealing surface 7 valve body 1 inboard, and metallic seal ball 5 places on this sealing surface 7.4 on the spring that is socketed on the positioning rod 3 acts on the metallic seal ball 5 all the time.When carrying out bleeding, because positioning rod 3 does not touch metallic seal ball 5 this moment, then the gas that is pressurized in the pipeline can overcome the elastic force of spring 4, comes out from metallic seal ball 5, outwards discharges through the exhaust port 6 of valve body 1 sidepiece.The quantity of valve body 1 sidepiece exhaust port 6 can be provided with 1 to 4 as required, and present embodiment is provided with 1.
As shown in Figure 2, after bleeding is finished, tighten exhaust bolt 2, make positioning rod 3 direct roof pressures on metallic seal ball 5.Like this, outlet valve is in closed condition all the time.
