Abstract

The utility model relates to a remote-control discharge valve for cisterns for automobiles and tractors, comprising a valve body, a valve core, a coil, a non-return clip, etc. The utility model has simple structure and convenient and reliable operation. The water of the cistern is discharged by the driver pressing the power switch in the driving cab. The utility model solves the problem that the transport vehicle has inconvenient water discharge in stopping in winter. The utility model can be used for the cisterns of other devices to discharge water.

Description

Remote control discharge valve for cistern

The utility model is a kind of water tank drain valve.It can be used for automobile, the tractor engine water tank discharges water, and also can be used for other device water tank use that discharges water.

As everyone knows, to winter, stop after automobile, tractor class means of transportation use time spent not long period, the water in its engine water tank must bleed off, and build-ups ice to prevent water, causes the engine body bursting by freezing and can not use, and produces bigger economic loss.At present the discharging valve that uses is direct manually operated type, and after promptly stopping, the driver will get into that loosening valve discharges water under the car, accidentally will be scalded, and dresses winter thicklyer, and it is also inconvenient to work together.

It is a kind of simple in structure, easy to use that the purpose of this utility model will provide exactly---the remote control drain valve that the driver just can bleed off water in operator cabin.

Technological scheme when realizing this is: a kind of water tank remote control drain valve of forming by valve body 2, spool 3, stage clip 7, line ladle shell 8, end cap 9, coil 12, and its special way is that spool 3 and stage clip 7 are housed in the valve body 2, and stage clip 7 is sleeved on the spool 3; By non-return card screw 4 rotating non-return card 13 and non-return card spring 5 are housed on the valve body 2; Valve body 2 and line ladle shell 8 usefulness scyewed joint are together; End cap 9 is pressed and is embedded on the line ladle shell 8; Gum cover 1 is equipped with at the accent place in the valve body 2.

In order to make spool 3 spacing in the course of the work, pin 6 is housed, normal opening and closing during with the assurance draining thereon.Its other end contacts with adjustment screw 10 on being installed in end cap 9, adjusts the stroke that screw 10 is used to adjust spool 3.

The utility model has the advantages that: safety, easy to operate, energy-conservation.

Accompanying drawing has been represented an embodiment of the present utility model, and Fig. 1 is assembling, the structural representation of water tank remote control drain valve; Fig. 2 is the plan view of Fig. 1, mainly reflects the shape of non-return card.Among the figure:

1---gum cover 2---valve body 3---spool 4---non-return card screw

5---non-return card spring 6---pin 7---stage clips

8---line ladle shell 9---end cap 10---adjustment screws

11---coil rack 12---coil 13---Ka Huika

Referring now to accompanying drawing embodiment is described.

When water tank need discharge water, the driver who is sitting in operator cabin clicks at the indoor power switch that has connected circuit, coil 12 energisings produce magnetic force, suction movable valve plug 3 moves to right and has opened drain valve, at this moment, the pin on the spool 36 promotes the relative movement that non-return card 13(produces along non-return card Dou face by pin) rotation of generation clockwise direction.When pin 6 continues to move to right when crossing the inclined-plane and entering gap position on the non-return card 13, under the effect of

non-return card spring

5,13 revolutions of non-return card, this course of action is to produce in the short time at the utmost point of connecting power supply.

When after hand clicks, leaving power switch, even without the magnetic force that spool 3 is moved to right, because this moment, pin 6 rested on the gap position of non-return card 13, stage clip 7 can not make spool 3 move to left, therefore, drain valve is opened always, the water in the water tank can have been put.

When needs are closed drain valve so that when adding water, the driver only need click power switch again, then magnetic force suction movable valve plug 3 moves to right, this moment is under the effect of non-return card spring 5, non-return card 13 continues revolution, pin 6 enters the groove of non-return card, because this moment, the position on the pin left side was a tip-tilted oblique structure, under the effect of stage clip 7, pin jack-up non-return card 13 and drive spool 3 and move to left and get back to the origin-location, (being fallen back to initial position by the effect of non-return card spring 5) by the non-return card 13 of jack-up thus closed drain valve.
