Description

Passenger vehicle SELF CL water-supply apparatus

The utility model is a kind of passenger vehicle SELF CL water-supply apparatus, belongs to valve field.

At present, mostly be common valve greatly to what water on the passenger vehicle used in AT STATION.Because there is certain distance at passenger vehicle and water source, cause many inconvenience for last water, also can cause the waste of water resource.This mainly is owing to after waterborne expiring, after Guan Shui need walk a segment distance, valve closing could have been strengthened labour intensity.Water in the water pipe can't reclaim, and can be lost in vain.In the winter time, water flows on the platform and can freeze, and causes potential danger.

The purpose of this utility model provides a kind of valve system that can SELF CL behind intact water on the water tank, is used for to water on the passenger vehicle.

Passenger vehicle SELF CL water-supply apparatus of the present utility model reaches upward by valve body, spool, latch, manual-lock bar, switch slide core backwater switch, and the water joystick constitutes; Have inlet opening, apopore, backwater hole, spool bore and body cavity in the valve body, the inlet opening communicates with spool bore and body cavity respectively, and apopore and backwater hole communicate with body cavity by a straight hole; Spool is inserted in the spool bore; Switch slide core top is the water blockoff lid, and the bottom is a guide, has some water holes on the guide, in the straight hole that it is packed into from body cavity with apopore and backwater hole communicate; Last water joystick is a piston type, and it is packed into from the other end in the hole of dress switch slide core; Latch is a plectrum or bar, hinge is housed on the one end links to each other with valve body, and the other end is stuck on the switch slide core, and its middle part is pressed on the spool; Manual-lock bar and switch slide core are contained on the same axis, and withstand on the switch slide core; Backwater switch is contained in the backwater hole; Backwater switch is made of switch seat, little water shutoff lid, big water shutoff lid, hook and driving lever, the centre of big water shutoff lid has the hole, it links to each other with switch seat by hinge on one side, little water shutoff lid links to each other with big water shutoff lid by hinge, and cover on the hole of big water shutoff lid, driving lever is contained in the outside of little water shutoff lid, and hook is contained in the inboard of little water shutoff lid, and pass in the hole of big water shutoff lid, be hooked in big water shutoff and cover.

The working process of this passenger vehicle SELF CL water-supply apparatus is: respectively inlet opening and backwater hole are communicated with water source and recovery tank, apopore links to each other by the filling pipe end of water pipe with the water tank of passenger vehicle.The water joystick moves in the promotion, drives the switch slide core simultaneously and moves the water blockoff lid of opening on it.Effect bottom spool in hydraulic pressure is pushed, and simultaneously latch piece jack-up is come, and latch piece is locked in the switch slide core on the position of unlatching again, keeps the water route unimpeded.In the process that last water joystick moves, can stir the driving lever on the backwater switch, cover the water shutoff lid and close backwater hole.After water is switched on, under the effect of hydraulic pressure and gravity, last water joystick playback.After the water tank fills with water, hydraulic balance, at this moment, under the effect of gravity and hydraulic pressure, switch slide core, spool and latch piece fall simultaneously, by the lid of the water blockoff on the switch slide core water source are cut off.In the process that the switch slide core moves down, it can stir the driving lever on the backwater switch, and the water shutoff lid is opened, and makes the surplus water in the water pipe flow into back water well by backwater hole.The manual-lock bar uses under special circumstances.It goes the pull switch slide core to cut off the water supply by external force and uses when opening backwater switch.This device can after water injection the back SELF CL, the problem that having overcome metals run out leaks, actv. conserve water resource.
