Abstract

The utility model discloses a liquid filling system with a compensation device. The liquid filling system comprises a liquid storage tank and a filling kettle connected with the liquid storage tank through a siphon, wherein a suction end of the siphon extends into the filled liquid in the liquid storage tank, and an outlet end extends into the filling kettle; a three-way joint is arranged on the siphon from the highest place to the outlet end of the siphon and is connected with an exhaust tank through an exhaust pipe; the exhaust pipe is provided with a control valve; the exhaust tank is located above the three-way joint; and the length of the siphon from the three-way joint to the outlet end is greater than that of the siphon from the highest place to the suction end of the siphon. In the utility model, the filled liquid compensation drainage for an automobile is realized according to the siphon principle; by adding the three-way joint to the siphon, the air in the siphon can be exhausted without sucking by a mouth, automatic drainage of the filled liquid under the gravity is realized, the operation is simple, and the harm to the human body caused by directly sucking the oil liquid with the mouth is avoided; and the device has simple structure, low cost and strong popularization, and is easy to implement.

Description

A kind of liquid filling system with compensating device

Technical field

The utility model belongs to automobile loading technique field, is specifically related to a kind of liquid filling system with compensating device.

Background technology

Siphon is a kind of fluid mechanics phenomenon, can be not by pump and pumping liquid.The liquid that is in the higher position is full of an inverted U-shaped tubular structure (being called siphon) afterwards, and the liquid of higher position then can be guided to lower position through siphon.Under this structure, the liquid pressure difference at pipe two ends can promote liquid and cross siphonal vertex, discharges to the other end.Promptly in connection pipe, create an environment under low pressure earlier, utilize the interior air pressure of pipe and the atmospheric draught head of high-order liquid levels, liquid is imported in the connection pipe; Treat that liquid passes through siphonal vertex; And after siphon outlet side liquid level is lower than high-order liquid level, under the effect of gravity, high-order liquid continuous inflow low level liquid container; The level height of liquid is identical up to high and low position, and liquid stops to flow.Utilize siphon principle must satisfy three conditions: 1, first filled with fluid in the pipe; 2, the vertex of pipe must not be higher than the height of water that barometric pressure is supported apart from the electrolyte level of upper container; 3, water outlet must be low than the water surface of upper container.Make the water outlet liquid level receive downward pressure (barometric pressure adds the pressure of water) like this, guarantee the outflow of water greater than the barometric pressure that makes progress.

In commercial production, siphon principle often is used in some easy liquid filling processes, like the filling of motor vehicle brake fluid, when the brake fluid charging in the filling kettle uses up, need compensate it; Usually the liquid storage kettle is positioned over higher position, the kettle of will annotating is positioned over lower position, through a siphon liquid in the liquid storage kettle is drawn and is flow in the filling kettle.But satisfy siphon principle, necessary full of liquid in its siphon, otherwise under the situation of air pressure greater than the liquid deadweight, liquid drainage smoothly.The most frequently used method is that the staff directly inhales with mouth at present, to get rid of inner air tube; But this mode is promptly inconvenient, causes easily again that misoperation will be harmful in the liquid suction body employee's health is caused damage, and is bigger to employee's injury when especially utilizing the siphon principle drainage to have corrosive liquid; This method also can be brought impurity to liquid simultaneously, influences liquid quality.

Summary of the invention

To the above-mentioned technological deficiency of existing in prior technology, the utility model provides a kind of liquid filling system with compensating device, utilizes siphon principle, need not mouth and inhales and can the air exhaustion in the siphon be realized the siphon water conservancy diversion.

A kind of liquid filling system with compensating device comprises:

The fluid reservoir of servicing fluids and the filling kettle that links to each other with fluid reservoir through siphon are housed; Described siphonal aspiration port stretches in the servicing fluids in the fluid reservoir, and exit end stretches in the filling kettle;

The siphon of siphon highest point to exit end is provided with T-pipe joint, and described T-pipe joint is connected with exhaust tank through freeing pipe, and described freeing pipe is provided with control cock; Described exhaust tank is positioned at the T-pipe joint top; The siphon length of T-pipe joint to exit end is greater than the siphon length of siphon highest point to aspiration port.

Preferably, described control cock is a ball valve; The flow of servicing fluids during the may command exhaust.

Preferably, in the described exhaust tank servicing fluids identical with fluid reservoir is housed; Can guarantee the servicing fluids quality.

The utility model utilizes siphon principle to automobile servicing fluids compensation drainage; Through on siphon, setting up T-pipe joint, need not mouth and inhale and can the air exhaustion in the siphon be realized servicing fluids automatic jet under gravity; Simple to operate; Avoid drawing the human injury that fluid causes with outspoken connecing, apparatus structure is simple, cost is low, be prone to enforcement, and generalization is strong.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

In order to describe the utility model more particularly, be elaborated below in conjunction with accompanying drawing and the specific embodiment technical scheme and drainage principle thereof to the utility model.

As shown in Figure 1, a kind of liquid filling system with compensating device comprises: fluid reservoir 1, filling kettle 2 and siphon 3; Braking liquid 4 is housed in the fluid reservoir 1; The aspiration port of siphon 3 stretches in the braking liquid 4 in the fluid reservoir 1, and exit end stretches in the filling kettle 2, and the liquid level height of living in of fluid reservoir 1 inside brake liquid 4 is higher than the exit end height of living in of siphon 3;

The siphon 3 of siphon 3 highest points to exit end is provided with T-pipe joint 5, and T-pipe joint 5 is connected with exhaust tank 6 through freeing pipe 7, and braking liquid 4 is housed in the exhaust tank 6, and freeing pipe 7 is provided with ball valve 8; Exhaust tank 6 is positioned at T-pipe joint 5 tops; Siphon 3 length of T-pipe joint 5 to exit end are greater than siphon 3 length of siphon 3 highest points to aspiration port.

When utilizing the compensating device of this embodiment that braking liquid 4 is compensated drainage, existing ball valve 8 is opened, braking liquid 4 by gravitys in the exhaust tank 6 along freeing pipe 7 in T-pipe joint 5 flows into filling kettles 2; At this moment; Air between joint to exit end in the siphon 3 is braked liquid 4 and discharges; This section volume of air enough is drawn into the braking liquid 4 in the fluid reservoir 1 highest point of siphon 3; Make that the braking liquid 4 in the fluid reservoir 1 can the by gravity automatic jets, thereby, form siphonic effect the air exhaustion in the siphon between aspiration port to joint 3; After air in the siphon 3 is discharged fully, close ball valve 8, accomplish the compensation drainage.
