Abstract
The utility model relates to the technical field of solution filling, in particular to an exhaust three-way structure of a solution precision filling system, which has a simple structure and reduces the use cost and comprises a liquid inlet pipe, a filling pipeline and an exhaust pipeline.
Description
Technical Field
The utility model relates to the technical field of solution filling, in particular to an exhaust three-way structure of a solution precision filling system.
Background
In the chemical production industries such as lithium battery processing, a solution is one of the most common raw materials, and the control of the filling amount of the solution has a great influence on the quality of a product, so that the solution filling system is started, and gas in a pipeline needs to be discharged in the solution filling process, so that the filling system is relatively complex and high in cost.
Disclosure of Invention
In order to solve the problems of complex exhaust structure and high cost of the existing filling system, the utility model provides an exhaust tee joint structure of a solution precision filling system, which is simple in structure and reduces the use cost.
The technical scheme is as follows: the utility model provides a solution precision filling system's exhaust three way structure, its includes feed liquor pipe, filling pipeline and exhaust pipe, its characterized in that, the outside cover of feed liquor pipe is equipped with the three-way pipe, the three-way pipe includes that both ends open-ended is responsible for and connects the bypass pipe of being responsible for the lateral wall, the feed liquor pipe is followed the lower extreme opening of being responsible for stretches into and the upper end surpasss the bypass pipe position, the lower extreme of feed liquor pipe expose in the three-way pipe, feed liquor pipe outer wall with be responsible for and be provided with sealing mechanism between the lower extreme opening, the upper end opening of being responsible for is connected the back pressure valve and first control valve exhaust pipe, the bypass pipe is connected the filling pipeline of second control valve.
The sealing mechanism is further characterized by comprising a pipe joint with the inner diameter in interference fit with the outer diameter of the liquid inlet pipe, wherein the pipe joint is connected with the three-way pipe through a hoop;
a circle of gap is reserved between the liquid inlet pipe and the main pipe.
After the solution enters the three-way pipe from the liquid inlet pipe, the first control valve on the exhaust pipeline is opened, the backpressure valve is closed, the second control valve is closed, the solution presses gas into the exhaust pipeline, the solution enters the filling pipeline under the action of backpressure influenced by the backpressure valve, the second control valve is filled, and the gas is exhausted after the gas pressure exceeds the limiting pressure of the backpressure valve.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
See fig. 1, an exhaust three-way structure of solution precision filling system, it includes feed liquor pipe 1, filling pipeline 2 and exhaust pipe 3, the outside cover of feed liquor pipe 1 is equipped with three-way pipe 4, three-way pipe 4 includes that both ends open-ended is responsible for 5 and is connected the bypass pipe 6 of being responsible for 5 lateral walls, feed liquor pipe 1 stretches into and the upper end surpasss bypass pipe 6 position from the lower extreme opening of being responsible for 5, the lower extreme of feed liquor pipe 1 exposes in three-way pipe 4, be provided with sealing mechanism between the lower extreme opening of feed liquor pipe 1 outer wall and being responsible for 5, the upper end opening of being responsible for 5 is connected the exhaust pipe 3 of backpressure valve and first control valve, the bypass pipe is connected the filling pipeline 2 of second control valve.
The sealing mechanism comprises a pipe joint 7 with the inner diameter in interference fit with the outer diameter of the liquid inlet pipe 1, and the pipe joint 7 is connected with the three-way pipe 4 through a clamp 8.
The working principle is as follows: solution is introduced into the liquid inlet pipe 1, the back pressure valve of the exhaust pipeline 3 is closed, the first control valve is opened, the second control valve of the filling pipeline 2 is closed, the solution enters the main pipe through the liquid inlet pipe 1, filling is started from the bottom, gas is discharged towards the exhaust pipeline 3, due to the existence of the back pressure valve, the solution enters the filling pipeline 2 under the action of back pressure, the second control valve is opened for filling, the back pressure valve is opened for exhausting when exceeding the set pressure, a small amount of solution can be taken out, after exhausting, the back pressure valve and the first control valve are both closed, and the solution only enters the filling pipeline 2.
Claims (3)
