Abstract

An energy-saving valve specially used for water supply of train water tank and platform flushing is characterized in that a valve core is a hollow cylinder with one closed end, a convex shoulder and an O-shaped ring are arranged on the peripheral wall close to the closed end, and a through hole is arranged along the radial direction; the lower bottom surface of the shaft is provided with an eccentric block which is matched with a rectangular groove on the surface of the valve core. When water needs to be fed into the water tank of the carriage, the water tank interface is contacted with the valve core outlet to press the valve core to displace towards the water inlet end of the valve body, and when the through hole on the valve core is communicated with the water inlet end, water is fed into the water tank. And after the water feeding is finished, the valve core is reset. The water supply is stopped.

The utility model can also use the handle to open the valve core for the platform to be washed.

Description

Power saving valve for water flushing on train

The utility model relates to valve, in particular for the water supply valve of train special use.

Train is the very big device of a kind of flowing power, and the passenger needs a large amount of domestic waters in the compartment that is flowing because the restriction of train water tank capacity, therefore often need be on each station platform water, for train operation and passenger's living needs.At present on the station platform generally with not with the direct water on the compartment water tank of the rubber water pipe of valve, caused a large amount of losses of tap water like this; And if load onto common valve at pipe outlet, the operator can be reluctant to use because of operating inconvenience.

To be that design is a kind of be specifically designed to train cistern water supply, easy to operate valve main purpose of the present utility model;

Another purpose is the double as shower nozzle, for the usefulness of flushing.

The purpose of this utility model is achieved in that

Spool is housed in valve body, this spool is an end osed top garden cylindricality central hole structure, radially have through hole near on the end perisporium of sealing surface, spool and valve body are with free-running fit, there is convex shoulder the end, cooperates with the valve body side, and fitting surface is equipped with O-ring seals, in order to promote resetting of spool, between the closed end of spool and joint, stage clip is housed.

There is eccentric block the lower surface of axle, matches with the rectangular channel of spool face, tightens with gland between axle and the valve body, on the axle control handle is arranged.

At the exit end of valve body, adopt rubber or have certain elastomeric plastics affixed with it, be convenient to and compartment water tank interface fit mutually.

The utlity model has simple in structure, reliable, multi-purpose valve and water-saving characteristics.

Below in conjunction with embodiment the utility model is specified:

Fig. 1 is the view when water rinsing energy-saving valve is not gone up water on the train;

Fig. 2 is the view during water on the energy-conservation valve.

As figure, be the garden tee section inside and outside the valve body 9, the one end is equipped with joint 1, and spool 11 is housed in valve body 9, and spool is the hollow garden of an end osed top post, has convex shoulder 10 and O-ring seals 4 to play thrust and sealing function with valve body by the outer wall of closed end.Near convex shoulder, radially have four uniform ellipse garden shape through holes 5, from near the through hole to the valve core opening end surfaces, have a rectangular channel 7 vertically, the width of rectangular channel adapts with axle 6 lower surface eccentric blocks, on the axle control handle 8 is arranged, the exit end of valve body 3 is hot-forming with rubber or soft plastic.

During use, joint 1 connects the rubber water pipe, after the water flowing, relies on the effect of O shape circle 4, and water can not flow out from spool 11.When the exit end of valve body entangles the last water interface of compartment water tank, interface contacts with the open end of spool 11, rely on thrust, make the entrance point displacement of spool to valve body 3, when the through hole 5 on spool is communicated with water (as Fig. 2 position), water flows out from the valve core opening end through the through hole on the spool, makes water enter water tank.After last water finished, the valve outlet end broke away from the water tank interface, relied on elastic force, made spool turn back to the initial position, and water outlet stops.

When the time spent of need do flushing, Spin Control handle 8 makes the eccentric block of axle 6 rely on rectangular channel 7 drive spools to move to the entrance point of valve body, and during to Fig. 2 position, high-velocity flow flows out from the valve core opening end; When control handle returned the initial position, water outlet stopped.

Claims

1, water rinsing energy-saving valve on a kind of train has valve body, and spool and axle with the valve body free-running fit is characterized in that spool (11) is the hollow Cylinder of an end osed top, radially have through hole (5) near on the perisporium of closed end.

2, energy-conservation valve as claimed in claim 1, it is characterized in that the axle (6) the lower surface on an eccentric block is arranged, match with the rectangular channel (7) of spool face.

3, energy-conservation valve as claimed in claim 1 is characterized in that spool leans on sealing surface one end that convex shoulder (10) is arranged, and O shape circle (4) is housed between the contact surface of convex shoulder and valve body side.

4, energy-conservation valve as claimed in claim 1 is characterized in that being equipped with between spool closed end and joint (1) stage clip (2).
