Abstract
A three-way angle cock for ensuring the safe braking of a train consists of a cock body (1), a cock copper core (2), a bottom cover (3), a square-head nut (4) and a handle (5), wherein in a full-through state, a through hole with the diameter of phi 12mm is formed in the center of the outer side of the cock body, the through hole penetrates through the wall thickness of the cock copper core, and then the cock copper core (2) is rotated by 180 degrees and is arranged in the cock body.
The device is characterized in that: when someone closes the angle cock intentionally or unintentionally, it will make all vehicles behind (or in front of) the angle cock automatically in a braking state, and the locomotive driver can find the angle cock in time.
Description
The utility model relates to a kind of threeway angle cock of guaranteeing the train safe braking.
What existing train braking device adopted is two logical angle cocks, because fault of construction, in case train is before driving, someone has a mind to or unintentionally a certain vehicle angle cock is closed, then certainly will cause locomotive that all vehicles after this vehicle are lost control of braking, cause that thus train conflict accident happens occasionally, cause heavy losses for the country and people's lives and properties.Only July in this year, system-wide just recurred three times this type of grave accident once.
The purpose of this utility model is the threeway angle cock that a kind of improved train safe braking will be provided, it not only can give anti-because of the artificial angle cock of a certain vehicle is closed causes that thereafter (or preceding) all vehicles lose the generation that braking mode causes train conflict grave accident effectively, and reduces the relevant personnel greatly and pluck the labour intensity of separating airduct.
The utility model is achieved in that at former two logical angle cock standard-sized sheets and leads to the position, processes the hole of a Φ 12MM from the external middle side part of plug door (angle cock, down together), and mistake cock copper core wall thickness, unload a plug door handgrip then,, put in back handgrip copper heart Rotate 180 °.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is the threeway angle cock semisectional view that provides according to utility model.
Fig. 2,3, the 4th, cock copper core are in different conditions lower edge A-A section-drawing.
Diagram: angle cock is by cock body 1, cock copper core 2, bottom 3, square toes mother 4, handgrip 5 compositions such as grade.
Longitudinal centerline becomes parallel position with the longitudinal centerline of plug door on Fig. 2 handgrip, angle cock is in the normal working of all-pass, both sides kidney passage on the cock copper core 2 and 1 liang of edge channel of cock body over against, pressurized air enters auxiliary reservoir by each vehicle trunk line smoothly, and Vehicular brake device is under the control that is subjected to hauling engine.
The longitudinal centerline of Fig. 3, spanner 5 becomes 50 ° of angles with the longitudinal centerline of plug door, Sai Men is in firm closed condition, both sides kidney passage on the cock copper core 2 and 1 liang of edge channel of cock body are just closed, cut off compressed-air actuated passage between the person in charge, original 500 kPas/CM in being responsible for by (or preceding) vehicle after the Guan Saimen
2Pressurized air begins from cock copper core 2 Φ 12MM half hole at this moment by exhaust to atmosphere gradually in kidney passage on one side and Φ 12MM half hole, cock body 1 right side, and the decompression rate of brake pipe is greater than 40 kPas/CM of per minute
2Thereby, making by (or preceding) vehicle after the Guan Saimen and produce braking, the engineer can realize that just the plug door is closed fault.
The longitudinal centerline of Fig. 4, handgrip 5 is vertical with the longitudinal centerline of plug door, and Sai Men is in buttoned-up status, and passage is cut off between the person in charge, original 500 kPas/CM in being responsible for by (or preceding) vehicle after the Guan Saimen
2Pressurized air is just crossed its kidney passage one side and the full Kong Zhongxiang atmosphere discharge of cock body right side Φ 12MM from the Quan Kongzhong of the Φ 12MM of the plug door heart 2, its pressure descends suddenly, produce braking, cause the locomotive desire moving can not, the engineer is very fast to realize that just the plug door is closed a fault.
Claims (1)
1, a kind of threeway angle cock of train safe braking, it is characterized in that when angle cock and trunk line are in the normal working of all-pass, open through hole, this through hole of a φ 12mm at the outer side center place of cock body (1) and pass the wall thickness of cock copper core (2), take out a plug door handgrip (5) then, cock copper core (2) Rotate 180 ° is put in back plug door knob (5).
