Abstract

The utility model provides an automobile expansion water tank, belonging to the technical field of automobiles. The automobile expansion water tank comprises a hollow tank body. A water inlet pipe and a water outlet pipe are provided on the tank body. The water inlet pipe and the water outlet pipe are communicated with the inner cavity of the tank body, and the inner end of the water inlet pipe extends to the inner cavity of the tank body. A pressure cover is installed on the outer end of the water inlet pipe. A leakage hole is provided on the side wall of the water inlet pipe and is communicated with the inner cavity of the tank body. A trap is provided in the leakage hole. The expansion water tank integrates a pressure hole with the water inlet pipe, which makes the tank body have simple and reasonable structure and reduces product cost. For overmuch water amount in the inner cavity is prevented by the air pressure of the inner cavity of the tank body, the utility model is of reasonable design.

Description

The automobile swelling water tank

Technical field

The utility model belongs to automobile technical field, the swelling water tank that uses on particularly a kind of automobile.

Background technique

In the cooling system of automobile, the effect of swelling water tank is to regulate the water yield in the radiator of car engine, prevents to enter in the cooling system air.Simultaneously, swelling water tank also can reduce the mistake of cooling hydrorrhea.

In existing swelling water tank, the top of casing is provided with two mouths: one is the mouth of pipe of intake pipe, and another is a pressure port.Pressure cover is housed on pressure port.When too high pressure is arranged in the casing, can air or water in the casing be overflowed by pressure cover, with release pressure.Intake pipe then is used to add water.Therefore, the two effect is inequality.But when reality was used, people often added from pressure port water mistakenly in swelling water tank, caused hypervolia in the casing, influenced the normal use of swelling water tank.

Summary of the invention

The purpose of this utility model is at the existing deficiency of existing automobile swelling water tank, and a kind of structure improved automobile swelling water tank is provided, and makes it have simple and reasonable, as effectively to avoid hypervolia in casing characteristics.

The purpose of this utility model can realize by following technical proposal: this automobile swelling water tank comprises a hollow casing, intake pipe and outlet pipe are arranged on the casing, intake pipe and outlet pipe all communicate with the inner chamber of casing, it is characterized in that, the inner of described intake pipe extends in the cabinets cavity, and a pressure cover is housed in the outer end of intake pipe.

In above-mentioned automobile swelling water tank, on the sidewall of intake pipe, be provided with one and omit the hole, omit the hole and communicate with the inner chamber of casing.Usually, in the omission hole trap is arranged.

This automobile swelling water tank is being added in the water process, and when the water that adds casing increased to the inner place of intake pipe, water blocking was lived in the inner mouth of pipe of water pipe, and the air in the swelling water tank can't be discharged.Along with the continuous adding of water, utilize to produce higher air pressure after air is compressed in the swelling water tank, stop that the water surface of inner chamber goes up, water can't be added, thereby prevent hypervolia in the casing.

In the using process of this swelling water tank, if higher air pressure is arranged in the swelling water tank casing, under the effect of air pressure, the water in the casing can rise along intake pipe so.But when water level rose to the place, omission hole of intake pipe, water can be got back in the cabinets cavity by omitting the hole.Certainly, if the air pressure in the casing is too high, water or air still can outwards discharge by pressure cover along the pressure cover that backs down the intake pipe outer end after intake pipe rises.

Compared with prior art, this swelling water tank makes the simple and reasonable of casing, and can reduce the cost of product because pressure port and intake pipe are united two into one.Because the air pressure by cabinets cavity prevents hypervolia in the inner chamber, it is reasonable in design, has higher utility.

Description of drawings

Fig. 1 is the structural representation of the automobile swelling water tank that provides of the utility model.

Fig. 2 is the partial enlarged drawing at intake pipe place in the automobile swelling water tank that provides of the utility model.

Among the figure, 1, casing; 10, inner chamber; 2, intake pipe; 3, pressure cover; 31, spring; 32, lid shell; 33, diaphragm seal; 34, release aperture; 4, outlet pipe; 5, omit the hole; 51, trap.

Embodiment

As shown in Figure 1, on the casing 1 of this automobile swelling water tank intake pipe 2 and outlet pipe 4 are arranged.In the present embodiment, casing 1 employing plastics are that material is made.The center of casing 1 is a hollow inner chamber 10.Intake pipe 2 and outlet pipe 4 all communicate with inner chamber 10.The outer end of intake pipe 2 is positioned at the upper lateral part of casing 1, and the inner of intake pipe 2 extends in casing 1 inner chamber 10.Outlet pipe 4 is positioned at the bottom of casing 1.

Water is inwardly added by intake pipe 2 places.By outlet pipe 4, water can be emitted.When swelling water tank used, outlet pipe 4 connected with the radiator of motor car engine.

As depicted in figs. 1 and 2, on the tube wall of intake pipe 2, there is one to omit hole 5.Omit in the hole 5 trap 51 is arranged.Under normal conditions, there is a spot of water in the trap 51 in omission hole 5, can plays the effect of baffle box intracoelomic cavity 10 air.In the present embodiment, omit hole 5 and be in intake pipe 2 position of portion on the upper side.

Obviously, adding in the water process from intake pipe 2, when the water surface rises to intake pipe 2 the inners, air in the swelling water tank is compressed because of discharging, form certain air pressure, block water flows to into cabinets cavity 10, and water can't be added from intake pipe 2, has avoided the phenomenon of hypervolia in the cabinets cavity 10 to occur thus.

A pressure cover 3 is housed in the outer end of intake pipe 2.As depicted in figs. 1 and 2, in the present embodiment, pressure cover 3 comprises a diaphragm seal 33 that covers in shell 32 and the lid shell 32, is provided with a spring 31 between lid shell 32 and diaphragm seal 33, at the sidepiece that covers shell 32 release aperture 34 is arranged.After swelling water tank adds water and finishes, just pressure cover 3 is loaded on the outer end of intake pipe 2.At this moment, diaphragm seal 33 roof pressure under the effect of spring 31 makes intake pipe 2 outer ends keep sealing state in the outer end of intake pipe 2.

In the swelling water tank using process, after the gas of engine radiator generation entered casing 1 from outlet pipe 4, casing 1 inner chamber 10 will produce higher air pressure.Under higher gas pressure, water can rise along intake pipe 2 in the inner chamber 10.Under normal conditions, water level rises to when omitting 5 places, hole in the intake pipe 2, and water can return in the inner chamber 10 by omitting hole 5.

But, if too high air pressure is arranged in the casing 1.Under the effect of air pressure, water or gas can overcome the resistance of spring 31, back down the diaphragm seal 33 on the pressure cover 3, discharge from the release aperture 34 of pressure cover 3.After being discharged into to a certain degree, the air pressure in the casing 1 also can be along with decline.At last, the diaphragm seal 33 of pressure cover 3 again roof pressure in the outer end of intake pipe 2.Be that swelling water tank is returned to original state again.
