Abstract

The utility model provides a water tank with an overflow device, which is used for high-health-demanding system pipeline such as purified water, high-quality drinking water, food and medical and so on. The utility model is characterized in that a support is arranged on the upper part of the internal wall of the water tank; a connecting pod is pined and joined on the support; a floating ball is connected with the front end of the connecting pod; a plug is connected in the middle of the connecting pod; an overflow pipe is correspondingly arranged on the lower part of the plug; a nozzle seat, which is matched with the plug, is installed at the nozzle of the overflow pipe. According to the use need, the overflow pipe stretches out from the side wall of the water tank or from the bottom of the water tank. When the liquid line is low, the plug is pressed into the nozzle of the overflow pipe by gravity, so the outer air and the inner liquid are separated. When the liquid rises to a relatively high line and needs to be exhausted, the floating ball ascends by buoyancy force, and the plug is driven by the floating ball and ascends, too; so the overflow nozzle is opened and the liquid flows out. The utility model has the good function of preventing bacteria from entering the tank and can prevent bacterial from entering the tank body through the overflow nozzle and polluting the mediums in the tank body. At the same time, the overflow function of the water tank is not lost.

Description

A kind of water tank of carry potential overflow device

Technical field

The utility model relates to the water tank technical field, belongs to a kind of water tank of carry potential overflow device.

Background technology

At present, in pure water, drink water, food medicine production, all can use water tank in a large number, and in numerous occasions or because of the needs of technology or because of the needs of laws and regulations or because the needs of health, medium in the water tank will be accomplished aseptic as much as possible, thereby can take various sterilizations, degerming inside and outside the water tank or every the bacterium measure, as ultraviolet ray, air filter etc.But, for water tank, generally all required the overflow measure, to avoid the phenomenon that liquid overflows; As everyone knows, the bleed off pipe general requirements is often opened and is unblocked.Like this, just entered container and created condition to bacterium, then very inapplicable for the occasion that hygienic requirements as mentioned above is higher.

In above-mentioned field, the measure of taking is that water tank is not provided with bleed off pipe at present, though perhaps establish bleed off pipe, the outer air of water tank is taked very strict sterilization, antibacterial measure.The former is unfavorable for preventing the generation of contingency, and the latter then relative cost is higher.

Summary of the invention

The purpose of this utility model provides a kind of water tank of simple in structure, easy to use, the reliable carry potential overflow device of safe and sanitary, it can prevent that the air that contains bacterium from entering in the water tank by bleed off pipe, accomplish to make medium and isolate from outer air in the water tank, can when injected media is too much, discharge again by bleed off pipe.

For achieving the above object, the utility model is taked following design scheme:

A kind of water tank of carry potential overflow device, the water tank that a sealing is arranged, it is characterized in that: be provided with a bearing on tank inner wall top, a hinged connecting rod on bearing, front end at connecting rod is connected with a ball float, be connected with a stopper at the middle part of connecting rod, correspondence is provided with bleed off pipe in the bottom of stopper, and the mouth of pipe place of this bleed off pipe is equipped with the mouth of pipe seat that matches with stopper.

According to using needs, described bleed off pipe stretches out or stretches out from water tank bottom from the water tank sidewall.

When the medium in the water tank during in normal liquid level, ball float and connecting rod, stopper are pressed in stopper the mouth of pipe of bleed off pipe under the effect of gravity, play the effect of blocking-up air; When the liquid level in the water tank was in abnormal state and promptly surpasses the warning liquid level and need get rid of outside the casing, ball float rose under buoyancy function and drives described stopper and promotes together, opens the overflow mouth of pipe, and liquid is discharged by bleed off pipe; After liquid level descended, under action of gravity, stopper was kept in the center, and still stopped up the overflow mouth of pipe with the blocking-up air.

The utility model has the advantages that: can block medium and case outer air in the case, reduce the pollution that brings thus, can after liquid level surpasses certain position, in time liquid be discharged again simultaneously, significantly reduce the secondary pollution that produces therefrom, again the normal relief function of not dehydration case.

Fig. 2 is Fig. 1 schematic top plan view.

Fig. 3 is a structural representation of the present utility model (bleed off pipe stretches out from water tank bottom).

The specific embodiment

Referring to Fig. 1, Fig. 2, shown in Figure 3, a kind of water tank of carry potential overflow device, the water tank 1 that a sealing is arranged, be provided with a bearing 5 on tank inner wall top, a hinged connecting rod 3 on bearing 5 is connected with a ball float 2 at the front end of connecting rod 3, be connected with a stopper 4 at the middle part of connecting rod 3, correspondence is provided with bleed off pipe 7 in the bottom of stopper 4, and the center line of the center line of stopper 4 and the overflow mouth of pipe is consistent, and the mouth of pipe place of this bleed off pipe 7 is equipped with the mouth of pipe seat 6 that matches with stopper 4.

According to using needs, described bleed off pipe 7 stretches out (see figure 1) or stretches out (see figure 3) from water tank bottom from the water tank sidewall.

Claims

1, a kind of water tank of carry potential overflow device, the water tank that a sealing is arranged, it is characterized in that: be provided with a bearing on tank inner wall top, a hinged connecting rod on bearing, front end at connecting rod is connected with a ball float, be connected with a stopper at the middle part of connecting rod, correspondence is provided with bleed off pipe in the bottom of stopper, and the mouth of pipe place of this bleed off pipe is equipped with the mouth of pipe seat that matches with stopper.

2, water tank according to claim 1 is characterized in that: described bleed off pipe stretches out from the water tank sidewall.
