Abstract
The utility model relates to an angle cock which is suitable for various type of air brakes, which is technically characterized in that an air exhaust hole is drilled on the lower part of the ventilating mark in the middle of the side of the valve body of the existing angle cock; the air exhaust hole is also drilled on the valve core, and the air exhaust hole is perpendicular and communicated with an original air passing hole. When the door being in the closed position, pressure air in the wind pipe of a train can be exhausted and the train is braked. When using, the utility model need not other brake devices without the influence of the directional limit of the train, can arbitrarily marshalling the trains. The angle cock has the advantages of simple structure, convenient improvement and safe use.
Description
The utility model relates to a kind of parts of brake system of rail vehicle, particularly a kind of angle cock, and it is applicable to the air damper of various models.
Existing angle cock is in railway transportation, if the angle cock of a certain vehicle of train is closed by the bad person, it has just cut off the path of train pipe, when train needs to slow down, during parking, can not discharge the pressure air in the train pipe, make the pressure air in the auxiliary reservoir can not enter brake cylinder, make the part vehicle can not produce brake action, the purpose of out of reach ramp to stop, and lead to train top shoe accident, caused certain loss for the country and people's lives and properties.
The purpose of this utility model is at above deficiency and disclosed a kind of angle cock, it is to close the generation that causes the train operation accident in order to reduce the railroad train mistake because of angle cock in service, and the improvement that the structure of existing angle cock is carried out, some angle cocks are closed even train is in operation, also can discharge the pressure air in the train line automatically, make train braking.
The utility model is achieved in that the handle jacket card 1 of angle cock is sleeved on spool side's body card 5 by lever pin 3, spool 6 is contained in the valve body 2, spring 9 is contained in the lower end of spool 6, gland 10 is fixed on the valve body 2, wherein, at the middle part, side of valve body 2 vent 7 is arranged, the axis normal of vent 7 is in the B--B section, on the spool 6 and cross on the perpendicular position, wind hole 8 vent 11 is arranged, vent 11 communicates with wind hole 8 excessively, and vent 11 and vent 7 are on sustained height.
The utility model also can be achieved in that vent 7 5mm place below the ventilation mark at the middle part, side of valve body 2; The aperture of vent 7 and vent 11 is 9mm.
Good effect of the present utility model is:
1, when angle cock is off position, can in time discharge the pressure air in the train line, make train braking.
2, be applicable to the air damper of various models, be not subjected to the restriction of type, be not subjected to the restriction of rail vehicle direction, arbitrarily marshaling.
3, need not to change other brake equipment.
4, this angle cock is simple in structure, and it is convenient to transform, and invest for a short time, safe and reliable, adds can not for driving department and bother.
Description of drawings is as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is an A--A cutaway view of the present utility model.
Fig. 3 is a part sectional view of the present utility model.
Wherein:
1, handle jacket card 2, valve body 3, lever pin
4, train pipe 5, spool side's body card 6, spool
7, vent 8, mistake wind hole 9, spring
10, gland 11, vent
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3.The utility model is that a vent 7 is bored at the 5mm place below the ventilation mark at the left surface middle part of the A-A section of the valve body 2 of existing angle cock, and the axis normal of vent 7 is in the B--B section.Bore a vent 11 with mistake 8 perpendicular positions, wind hole on spool 6, vent 11 communicates with crossing wind hole 8, and vent 7 and vent 11 are on sustained height, and the aperture of vent 7 and vent 11 is 9mm.When train (each angle cock is open stance) needs in the operation way slow down or stop, the driver should be positioned over service application position to big lock handle, discharge the part air in the train pipe 4, causing the master of each vehicle triple valve to collude shellfish moves outward, drive exhaust valve and close vent, open supply port makes the pressure air of the auxiliary reservoir of vehicle enter brake cylinder, makes train produce brake action.Angle cock of the present utility model is in service at rail vehicle, does not change other brake equipment.When using the utility model, if running into improper mistake closes, this angle cock can be discharged the pressure air in the train pipe 4 automatically from vent 11 and the vent on the valve body 27 on the spool 6, make the pressure air in the auxiliary reservoir enter brake cylinder generation brake action rapidly, thereby reach the purpose of ramp to stop, guaranteed traffic safety.
Claims (3)
1, a kind of angle cock, comprise that handle jacket card 1 is sleeved on spool side's body card 5 by lever pin 3, spool 6 is contained in the valve body 2, spring 9 is contained in the lower end of spool 6, and gland 10 is fixed on the valve body 2, it is characterized in that: there is a vent 7 at the middle part, side at valve body 2, the axis normal of vent 7 is in the B--B section, on the spool 6 and cross on the perpendicular position, wind hole 8 vent 11 is arranged, vent 11 communicates with wind hole 8 excessively, and vent 11 and vent 7 are on sustained height.
2, angle cock according to claim 1 is characterized in that: vent 7 is the 5mm place below the ventilation mark at the left surface middle part of the A-A of valve body 2 section.
3, angle cock according to claim 1 is characterized in that: the aperture of vent 7 and vent 11 is 9mm.
