Abstract
The utility model relates to a double-way safety angle cock which comprises a cone cock rotary valve (11), an angle cock body (12), a rotary valve spring (15), a lower cover (14) and a handle (18). A plunger valve cavity cylinder (13) is arranged in the cone cock rotary valve (11), and a plunger valve spring (6), a plunger valve (5) which is provided with a sealing ring (19) and a plunger hole lower seat (10) are arranged in the plunger valve cavity cylinder (13) in sequence. The plunger hole lower seat (10) is connected with the plunger valve cavity cylinder (13) in the mode of screw connection, a hole (3) is arranged on the plunger hole lower seat (10), and holes (1, 4, 2, 7 and 8) are arranged on the cone cock rotary valve (11). When the angle cock is closed during vehicle running time, the angle cock is in a front and back penetrating state under the regulation of the plunger valve (5), and the safety of the vehicle running can be ensured.
Description
One, technical field
Utility model relates to a kind of valve, is applicable in the brake system of rail vehicle.
Two, background technology
Angle cock in the vehicle brake conduit is owing to closed in the driving by mistake at present, and the driver can't brake vehicle, causes the driving grave accident.
Three, summary of the invention
The utility model solves the safety of driving, and a kind of binary channel safety angle cock is provided.
The feature of this angle cock is, establishes a plunger valve pocket tube in cone plug door rotovalve, following of the plunger valve of erection column plug valve spring, band seal ring and plunger hole successively in the plunger valve pocket tube; Plunger valve and plunger valve pocket tube running-fit, following of plunger hole and plunger valve pocket tube are threaded in the lower end of plunger valve pocket tube, establish a through hole on following of the plunger hole; Cone plug door rotovalve is provided with 3 breather ports and a warning port; When angle cock was closed, under the adjusting of plunger valve, angle cock still was the front and back breakthrough status in the driving, and the driver can handle the damped condition that the locomotive automatic brake valve is controlled full rail vehicle normally, to guarantee the safety of driving.

Among the figure: hole 1,2,3,4, plunger valve 5, plunger valve spring 6, let out wind hole 7, warning port 8, cavity passage 9, following 10 of plunger hole, cone plug door rotovalve 11, angle cock body 12, plunger valve pocket tube 13, lower cover 14, rotary valve spring 15, brake hose side 16, brake pipe side 17, handle 18, seal ring 19
Five, specific embodiment
This safe angle cock, comprise:, angle cock body 12, rotary valve spring 15, lower cover 14, handle 18, it is characterized in that: in cone plug door rotovalve 11, establish a plunger valve pocket tube 13, erection column plug valve spring 6, plunger valve 5, plunger valve 5 are provided with two seals circle 19, following 10 of plunger hole successively in the plunger valve pocket tube; Plunger valve 5 and plunger valve pocket tube 13 running-fits, following 10 of plunger hole and plunger valve pocket tube 13 are threaded in the lower end of plunger valve pocket tube 13; Cone plug door rotovalve 11 is provided with hole 1, hole 4, hole 2, warning port 8, lets out wind hole 7, hole 3 is located on following 10 of the plunger hole.
17 termination brake pipes of angle cock, 16 termination brake hoses.
When this angle cock is in and opens, as shown in Figure 1.The cavity passage 9 of cone plug door rotovalve 11 has been linked up the brake pipe side 17 of this angle cock and the path at brake hose side 16 two ends, make angle cock be the front and back breakthrough status, the pressure air that hauling engine is supplied with whole rail vehicle brake system can circulate in brake pipe smoothly, and the driver then can handle the damped condition that the locomotive automatic brake valve is controlled full rail vehicle normally.
In the train operation, when this angle cock is closed by mistake, as shown in Figure 2.As closed by mistake be the angle cock of 2 of vehicle operating direction back the time, to present following situation: cone plug door rotovalve 11 is along with angle cock handle 18 rotates, cavity passage 9 forwards the sidewall of angle cock body 12 to, and the passage of former perforation brake pipe side 17 and brake hose side 16 is interdicted.But the hole 1 of the cone plug door rotovalve 11 when this position faces brake pipe 17 directions one side, and hole 4 faces brake hose 16 1 sides.At this moment, though brake hose one side is the rear portion braking of train, but the pressure air that also keeps original hauling engine supply in this side, the pressure air of brake hose side 16 is through the below of via hole 4 → plunger valve 5, the operating value that is set at plunger valve 5 because of the elastic force of plunger valve spring 6 is 190kpa, so the pressure air of brake hose 16 1 side 600kpa moves, after moving on the plunger valve 5, linked up the path in 4 → hole, hole 1 on via hole 4 → jack-up plunger valve 5; When moving on the plunger valve 5, hole 3 has been opened in the bottom of plunger valve 5; So just realized the communication of 4 → plunger valve, 5 belows, hole → 3 → lower cover, 14 → hole, hole, 2 two paths.Still can continue to keep the situation that front and back connect before and after making train brake pipe, the driver can handle the damped condition that the locomotive automatic brake valve is controlled full rail vehicle.
In the train operation as closed by mistake be the angle cock of 1 of vehicle operating direction front the time, because brake hose 16 sides are the locomotive direction, to realize aforesaid function equally, can continue to keep the situation that front and back connect before and after making train brake pipe easily, the driver can handle the damped condition that the locomotive automatic brake valve is controlled full rail vehicle, and the safety of train is protected.
Pressurized air when this situation is through the warning port 8 → atmosphere above wind hole 7 → plunger valve 5 of letting out on cone rotovalve 11 right sides.Only be 2mm owing to let out the aperture in wind hole 7, the aperture of warning port 8 is 3.5mm, the logical again atmosphere of warning port 8, and the air pressure that acts on plunger valve 5 tops like this is lower than the pressure of plunger valve 5 belows, has just guaranteed the realization of plunger valve 5 regulatory functions.
Warning port 8 is set two purposes, and the one, the operating personnel appears warning when mistake is closed when train is tested at the originating station; The 2nd, in when, mistake taking place in train operation closing, the decline warning prompt trainman who utilizes the leakage of warning port 8 to cause the train braking pipe pressure.
Fig. 3 is the angle cock close stance.During this operating mode, plunger valve 5 covers hole 1 and hole 3, the logical atmosphere of brake hose side 16, and angle cock is in normal closed condition.
Fig. 4 is the A-A cutaway view of angle cock.Plunger valve 5 and hole 2,1 position in cone plug door rotovalve 11 concerns as seen from the figure.
