Abstract

The utility model relates to a sealing device for automatically cutting off water sealing for a water tank. The sealing device is composed of a valve body, a valve core, a lever bracket and a float. A water channel in the sealing device is communicated with a hole of the valve core. The valve core is controlled by the float. When the valve core moves outwards, a clearance gap is arranged between a conical point on the valve core and the interface of the conical surface of the hole of the valve core. Water can enter the water tank. The float floats upwards. A float lever leads a lever bracket to overturn upwards. A regulating screw on the float lever drives the valve core to move inwards. The conical point on the valve core and the interface of the conical surface of the hole of the valve core are tightly approached. The water channel is closed enforcedly. The water can not enter the water tank. The sealing device for automatically cutting off water sealing for a water tank has the advantages of simple structure, high pressure resistance and good sealability. The sealing device for automatically cutting off water sealing for a water tank can be arbitrarily accommodated according to the requirement of water storage in the water tank.

Description

Sealing device for water tank automatic cutting off

A kind of water tank closes water sealing device automatically, belongs to the automatic water turn-off device in the common mechanical class.

At present water tank adopt ball float control sealing gasket more mode to current shutoff by force, sealing gasket is often because hydraulic pressure is excessive or because of containing impurity such as sand grains in the water or because of aging, intensity reduces and damages, and causes different the leaking of degree, the interior water spill-over of case goes out, and causes waste.

The purpose of this utility model provides a kind of long service life, withstand voltage height, good airproof performance, the automatic pass water sealing device that can regulate according to the requirement of moisture storage capacity.

The purpose of this utility model is achieved in that and has a spool bore in valve body one end vertically, this front portion, hole is a conical surface interface, axial water channel in the vertex of a cone of this interface and the valve body the other end communicates, individual water outlet is arranged at the bottom of spool bore, an end poppet valve core is housed in the spool bore, there is a spool connecting plate with holes at the planar end surface center at this spool rear portion, there is individual attachment hole horizon bar one termination of being inverted the lever dolly of T word shape, link to each other with the axis hole that is connected of bottom, valve body termination with pin, individual tapped hole is arranged in the other end of horizon bar, the floating ball lever of termination bracelet screws in wherein, there is individual tapped hole the vertical riser end of lever dolly, the adjusting screw that the end has an attachment hole was revolved from its hole, penetrated in the hole of its termination with pin again and in the hole of spool connecting plate, they was coupled together.

When in the case when anhydrous, ball float relies on the weight of self sagging, by lever dolly and the adjusting screw on this, spool is pulled outwardly out certain distance vertically, be that the conehead surface of spool and the conical surface interface of spool bore have had certain clearance, current flow into from water channel, enter in the case from water outlet, water level rises gradually in the case, and ball float also floats gradually and drives lever dolly upwards upset gradually, and the adjusting screw on it promotes spool and moves inwards, its conehead surface is pressed close to gradually with conical surface interface, and then be adjacent to, by force water channel is blocked, and stop into water.

When desire strengthens moisture storage capacity in the case, can be with the rotation of adjusting screw inhour, spool has promptly been strengthened its distance of returning, thereby has increased the height that ball float rises by to picking out certain distance, has promptly increased the moisture storage capacity in the case.Desire reduces the moisture storage capacity in the case, and the adjusting screw that turns clockwise gets final product.No matter be clockwise or after the inhour rotation adjusting screw, must must guarantee that the pin that adjusting screw is connected in the plate hole with spool is in level, otherwise will influence transmission even can not transmission.

Because the conehead of spool is made with rubber, the high resilience greatly again of its intensity, the surface of contact of itself and conical surface interface is bigger, thereby sealing is strong, and it is yielding and damage to bear higher hydraulic pressure.

Owing to adopted such scheme, make the utility model reach strong, the withstand voltage height of sealing and look the purpose that the requirement of case inner storing water amount can be regulated, it is simple in structure, long service life.

Below in conjunction with accompanying drawing enforcement of the present utility model is further described.

Accompanying drawing is a structural drawing of the present utility model.

Among the figure, 1, valve body; 2, spool bore; 3, conical surface interface; 4, spool; 5, conehead; 6, slide block; 7, spool connecting plate; 8, lever dolly; 9, connect axis hole; 10, adjusting screw; 11, water channel; 12, water outlet; 13, floating ball lever; 14, ball float; 15, pipe joint.

Among the embodiment shown in the figure, have spool bore ［ 2 ］ in valve body ［ 1 ］ right-hand member, there is individual conical surface interface ［ 3 ］ its front portion, there is individual water outlet ［ 12 ］ valve body ［ 1 ］ below of locating near conical surface interface ［ 3 ］, have water channel ［ 11 ］ in valve body ［ 1 ］ left end, this water channel communicates with the top of the conical surface interface ［ 3 ］ of spool bore ［ 2 ］ behind undergauge, spool ［ 4 ］ is by constituting for garden cylindrical slide made from engineering plastics movingly ［ 6 ］ and the conehead made from rubber ［ 5 ］ with spool bore ［ 2 ］, there is a spool connecting plate ［ 7 ］ with holes slide block ［ 6 ］ right-hand member planar central position, this hole is individual radially long, axially narrow oblong aperture.It is the little garden post of φ 4.1mm that there is a long 6mm diameter in the hole that it is φ 4mm that there is a dark 7-8mm diameter at slide plate ［ 6 ］ left end center, conehead ［ 5 ］ ear end face center, and it is pressed in the hole of slide block ［ 6 ］.The horizon bar left part of lever dolly ［ 8 ］ bottom of inversion T word shape is flat, individual attachment hole is arranged on it, be connected with the axis hole ［ 9 ］ that is connected of valve body ［ 1 ］ right-hand member bottom with pin, the right-hand member of horizon bar has individual interior threaded hole, the floating ball lever of termination bracelet ［ 13 ］ screws in wherein, there is individual tapped hole (center to the centre distance that is connected axis hole ［ 9 ］ of the attachment hole of the center in this hole to the centre distance that connects axis hole ［ 9 ］ and the spool connecting plate ［ 7 ］ equates) the vertical riser end of lever dolly ［ 8 ］, after from then on the adjusting screw ［ 10 ］ that there is an individual attachment hole at flat place, end revolved certain distance in the hole, penetrate in the attachment hole of adjusting screw end with pin and in the attachment hole of spool connecting plate ［ 7 ］, they are connected with each other, spool connecting plate ［ 7 ］ and adjusting screw ［ 10 ］ should be adjusted to suitable position before wearing pin, guarantee that pin can level penetrate, after also can penetrating pin, rotation adjusting screw ［ 10 ］ is adjusted to level with pin.
