Abstract

The utility model relates to an automatic water turning off and on valve of a cistern, which is composed of a valve body, a valve core, a lever bracket, a connecting rod and a floating ball. A water channel in the utility model is communicated with a pore channel of the valve core, and the axial movement of the valve core is controlled by the floating ball. When the valve core moves up, a gap is generated between a conical surface interface of the pore channel of the valve core and a conical point of the valve core, and thus, water can enter the cistern. The lever bracket is driven to move by the upward floating of the floating ball to cause the valve core to move down, and the conical point is pressed against the conical surface to block the water channel to stop water inflow. The automatic water turning off and on valve has the advantages of easy manufacture, strong sealing performance, long service life and capability of regulating the water storage of the cistern.

Description

Automatic water cut-off or intake valve for water tank

The utility model relates to a kind of water tank and closes the water inlet valve automatically, and it belongs to water valve.

Water tank adopts the mode of ball float control sealing gasket to current shutoff by force more at present, sealing gasket often because hydraulic pressure is excessive or because of contain in the water impurity such as sand grains or because of wear out, intensity reduces to damage, cause different the leaking of degree, the water spill-over goes out in the case, causes waste.

The purpose of this utility model, be to provide a kind of long service life, good airproof performance, again can the regulating tank moisture storage capacity water tank close the water inlet valve automatically.

For achieving the above object, the utility model is realized by following scheme.This valve is made of valve body spool, lever dolly, connecting rod and ball float.Be characterized in, valve body is made of the spool cavity of upper end and the pipe joint of lower end, in the spool cavity, offer axial spool duct, the bottom, duct is a conical surface interface, water channel in the vertex of a cone of this interface and the lower end pipe joint communicates, and offers a water outlet with the perforation of spool duct in spool cavity bottom, and its cylindrical place, upper-end surface is provided with a journal stirrup, have attachment hole on it, so that link to each other with lever dolly " T " cabinet frame; Spool is to be made of spool traveller and spool conehead, a blind hole is offered in the center, lower end surface of traveller, the planar end surface center of conehead is provided with a short cylindrical, blind hole and short cylindrical are interference fit, the traveller upper-end surface is crossed the center and is provided with a plate, have attachment hole on it, so that link to each other with adjusting screw; Lever dolly by a level put " T " cabinet frame and adjusting screw and on locking nut constitute, the lower end of the vertical side of " T " cabinet frame offers plat slot and attachment hole; The upper-end surface of this vertical side offers tapped hole, this tapped hole links to each other with connecting rod, and the connecting rod front end is a ball float, and " T " cabinet frame horizontal edge is offered a through hole, it is cylindric and offer plat slot and attachment hole, the screwed screw of epimere that through hole is installed with hypomere, and this screw is furnished with locking nut.

Accompanying drawing is a structural representation of the present utility model.Wherein 1 is valve body, and 2 is water outlet, and 3 is the spool conehead, and 4 is the spool traveller, and 5 is journal stirrup, and 6 is connecting plate, and 7 is " T " cabinet frame, and 8 is adjusting screw, and 9 is locking nut, and 10 is connecting rod, and 11 is ball float.

In conjunction with the accompanying drawings the utility model being implemented to close water and regulating tank process water automatically describes.When drawdown in the water tank arrives certain position, ball float sinks by the gravity of self, the drive lever dolly rotates, spool is upwards mentioned vertically, be that the conehead surface of spool and the conical surface interface in spool duct leave, the water channel of ambient pressure water in pipe joint enters the valve opening road, enters water tank from water outlet then.Along with the rising of water level in the water tank, ball float also floats thereupon, and drives lever dolly and rotate and reset, and is about to spool and passes downwards, until the conehead surface is adjacent to conical surface interface, so by force water channel is blocked, stops into water, has realized automatic pass water.

Desire will change the moisture storage capacity in the water tank, as long as adjust the length of adjusting screw, the nut of locking then on it gets final product.If the increasing moisture storage capacity promptly improves the distance of ball float and water tank bottom surface, at this moment transfer minor joint screw, if reduce the moisture storage capacity in the water tank, transfer long adjusting screw to get final product.

Valve body of the present utility model, spool traveller all can adopt engineering plastics to make, this makes the making facilitation on the one hand, the problem that does not have fouling to get rusty in addition, thereby guaranteed to close the leakproofness of water, again because the spool conehead adopts rubber to make the high resilience greatly again of its intensity, thereby sealing is strong, bear the not yielding and damage of higher hydraulic pressure, so can reach good seal performance fully, the purpose of long service life.

Claims

1, a kind of water tank closes the water inlet valve automatically, and it is made of valve body, spool, lever dolly and connecting rod, ball float.It is characterized in that: valve body is made of the pipe joint of upper end spool cavity and lower end.Offer axial spool duct in the spool cavity, the bottom, duct is a conical surface interface, water channel in the vertex of a cone of this interface and the lower end pipe joint communicates, and a water outlet that connects with the spool duct is offered in spool cavity bottom, and its cylindrical place, upper-end surface is provided with a journal stirrup of being with attachment hole; Spool is made of spool traveller and spool conehead, and a blind hole is offered in the center, lower end surface of traveller, and the planar end surface center of conehead is provided with a short cylindrical, and blind hole and short cylindrical are interference fit, and the connecting plate that the center is provided with the band attachment hole is crossed in the traveller upper-end surface; " T " cabinet frame that lever dolly is put by level and adjusting screw and on locking nut constitute, plat slot and attachment hole are offered in " T " cabinet frame vertical side lower end, tapped hole is offered in its upper end, " T " cabinet frame horizontal edge is offered a through hole, it is cylindric and offer plat slot and attachment hole to be installed with the lower end on the through hole, the threaded screw of epimere is furnished with locking nut on it.
