Description

an exhaust connector

technical field

The utility model relates to the technical field of an expansion tank, in particular to an exhaust connector.

Background technique

Expansion water tanks are installed in all types of cars currently designed, produced, and used to supplement the coolant in the cooling line, balance the pressure in the line, and discharge the air in the line. At present, the exhaust pipe of the expansion tank and the main pipe are basically connected by ordinary straight tees.

When the fluid flows rapidly in the straight connecting pipe, the gas bubbles are located in the upper layer of the pipe because the density of the gas is lower than that of the liquid. The exhaust channel of the ordinary three-way is perpendicular to the axis of the linear channel. The liquid in the exhaust channel is in a stagnant or slightly moving state. The liquid entrains air bubbles and flows through the exhaust channel of the three-way. According to the Bernoulli equation, the liquid is subjected to upward pressure. Force, the gas-liquid separation process is very short, the liquid flow rate is large, and the air bubbles are easily brought back to the horizontal pipe under the action of the liquid viscous force, resulting in poor air-expelling effect. Therefore, the ordinary straight tee used in the exhaust pipe of the expansion tank and the main pipeline cannot quickly and effectively discharge the air bubbles in the pipeline, especially when the viscosity of the coolant is high and the flow rate of the liquid in the pipeline is fast. The cooling liquid in the pipeline will form many small bubbles with the air. Due to the fast flow rate, the small bubbles will be pushed forward by the fast-flowing liquid in the pipe when passing through the straight tee, and only some small bubbles can pass through the branch pipe of the straight tee. Enter the exhaust pipe of the expansion tank, and then flow into the expansion tank. Due to the poor thermal conductivity of the air, the air bubbles remaining in the pipeline will affect the heat dissipation effect of the heat exchanger and the cooled device; at the same time, the undischarged air in the pipeline will affect the normal operation of the water pump.

Therefore, there is an urgent need for an exhaust connector that can quickly and effectively discharge the air bubbles in the water to ensure the normal operation of the water pump.

Utility model content

The main purpose of this utility model is to provide a new type of exhaust connector. The technical problem to be solved is that the bubbles contained in the liquid cannot be discharged smoothly, which leads to the failure of the normal operation of the cooling pipeline.

The purpose of this utility model and its technical solution are to adopt the following technical solutions to achieve. According to a kind of exhaust connector proposed by the utility model, comprising:

The connecting pipeline has a water inlet at its first end, a water outlet at its second end, and an exhaust port connected to its side wall;

The exhaust port communicates with the drainage channel of the communication pipeline to form an exhaust channel, and the port where the exhaust channel communicates with the drain channel extends obliquely toward the water inlet.

The purpose of the utility model and the solution to its technical problems can also be further realized by adopting the following technical measures.

Preferably, in the aforementioned exhaust connector, the axis of the drainage channel is a horizontal straight line.

Preferably, in the aforementioned exhaust connector, the axis of the exhaust channel is a straight line, and the included angle between the axis of the exhaust channel and the axis of the drainage channel is 30°-60°.

Preferably, the aforementioned exhaust connector, wherein the exhaust channel includes a first section and a second section that are bent and communicated with each other, and the first section communicates with the drainage channel;

Preferably, the aforementioned exhaust connector, wherein the communication pipeline is integrally formed through a casting process.

With the above technical solution, the utility model connector has at least the following advantages:

After adding the structure of the inclined exhaust channel on the basis of the ordinary tee, when the fluid mixed with air bubbles flows through the exhaust tee, the air bubbles move upward along the inclined pipe wall on the upper side, which is suitable for the separation of air bubbles and liquid. The process of liquid separation is longer; at the same time, the exhaust channel is close to the water outlet, and its structural shape will slow down the flow velocity of the fluid there, so the air bubbles are less viscous force of the liquid and are not easily brought back to the horizontal channel by the liquid, thus achieving Efficient degassing effect ensures the normal operation of the pump.
