Description
Technical field
The utility model belongs to vacuum sizing box technology field, is specifically related to a kind of water-level control apparatus of vacuum sizing case.
Background technology
Plastic pipe in process of production, the pipe fitting of extruding through extruder has higher temperature, and indefinite form.Way commonly used is, pipe fitting process vacuum sizing case with extruding utilizes the negative pressure swabbing action in the sizing case, the pipe fitting that still is in soft state is radially extended out form circle, utilize the cooling water in the casing to spray cooling simultaneously, thereby reach the effect of hole enlargement typing.Existing vacuum sizing case generally is after pipe fitting enters vacuum sizing case cooling section, and self circulation line of water conservancy in the casing carries out the circulated sprinkling cooling to pipe fitting, realizes the cooling and shaping effect to pipe fitting.But in production practices, find when cooling water in the casing of vacuum sizing case during circulated sprinkling, owing to after cooling water and the pipe fitting heat exchange cooling water temperature is constantly risen, and the water level instability in the cooling water circulation time casing, make the vacuum in the casing also unstable, thereby have influence on the quality of pipe fitting.For solving this technical problem, available technology adopting is installed liquid level sensor in the casing of vacuum sizing case, controls corresponding magnetic valve and opens and closes, and makes to keep stable liquid level in the vacuum chamber.But owing to liquid level sensor is immersed in the water often, and the temperature in the casing is higher, causes the high and damage easily of level sensor fault rate, often causes the out of control of system.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of can the realization and intakes automatically and draining, make the liquid level in the casing keep stable, can improve control accuracy again, reduce the vacuum sizing case water-level control apparatus of level sensor fault rate.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of water level automatic control device of vacuum sizing case, comprise casing, shower, water circulating pump and water supply tank, be provided with a water level induction cup on described casing side, described water level induction cup bottom was communicated with circulated sprinkling water in the casing by communicating pipe, be provided with water level upper limit inductor and water level lower limit inductor in the water level induction cup, water level upper limit inductor is connected with drain solenoid valve by controller, described drain solenoid valve is arranged on the drainpipe of casing, water level lower limit inductor is connected with entering water electromagnetic valve by controller, described entering water electromagnetic valve is arranged on the water inlet pipe of casing and with water supply tank and is connected, and described water level induction cup top is connected by the position that vacuumizes in vacuum tube and the casing.
The circulated sprinkling water level upper limit height that will control in the nozzle position of water level upper limit inductor described in the utility model and the casing is consistent.
The circulated sprinkling water level lower limit height that will control in the nozzle position of water level lower limit inductor described in the utility model and the casing is consistent.
Compared with prior art, the beneficial effects of the utility model have: owing to be provided with water level upper limit inductor and water level lower limit inductor in the water level induction cup, with water level induction cup bottom by communicating pipe with after circulated sprinkling water in the casing is communicated with, water level upper limit inductor and water level lower limit inductor just can detect the water level of the circulated sprinkling water in the casing, because water level sensor is not arranged in the casing of vacuum sizing case, so just avoided the hot and humid environment of water level sensor contact, effectively reduce the fault rate of water level sensor, so can accurately control the liquid level of the circulated sprinkling water in the vacuum sizing case and the vacuum that vacuumizes, improve the crudy of pipe fitting.

Among the figure, 1-casing, 2-shower, 3-water inlet pipe, 4-entering water electromagnetic valve, 5-water supply tank, 6-drain solenoid valve, 7-drainpipe, 8-communicating pipe, 9-water level induction cup, 10-water level lower limit inductor, 11-water level upper limit inductor, 12-vacuum tube, 13-controller.
The specific embodiment
A kind of water level automatic control device of vacuum sizing case, comprise casing 1, shower 2, water circulating pump and water supply tank 5, be provided with a water level induction cup 9 on described casing 1 side, described water level induction cup 9 bottoms were communicated with circulated sprinkling water in the casing 1 by communicating pipe 8, be provided with water level upper limit inductor 11 and water level lower limit inductor 10 in the water level induction cup 9, water level upper limit inductor 11 is connected with drain solenoid valve 6 by controller 13, described drain solenoid valve 6 is arranged on the drainpipe 7 of casing 1, water level lower limit inductor 10 is connected with entering water electromagnetic valve 4 by controller 13, described entering water electromagnetic valve 4 is arranged on the water inlet pipe 3 of casing 1 and with water supply tank 5 and is connected, and described water level induction cup 9 tops are connected by the position that vacuumizes in vacuum tube 12 and the casing 1.
Operation principle of the present utility model is: owing to be provided with water level induction cup 9, behind water level upper limit inductor 11 and the water level lower limit inductor 10, with water level upper limit inductor 11 with after drain solenoid valve 6 on being located at casing 1 drainpipe 7 is connected, after the circulated sprinkling water level in the casing 1 arrives the nozzle position of water level induction cup 9 middle water level upper limit inductors 11, water level upper limit inductor 11 is given controller 13 feedback signals, controller 13 starts drain solenoid valve 6, close entering water electromagnetic valve 4 simultaneously, unnecessary circulated sprinkling water in the casing 1 is discharged, make the certain space of casing 1 inner maintenance of vacuum sizing case, make things convenient for the suction of vavuum pump, to keep the negative pressure state in the casing 1.Since with water level lower limit inductor 10 with after entering water electromagnetic valve 4 on being located at casing 1 water inlet pipe 3 is connected, when the circulated sprinkling water in the casing 1 drain into water level induction cup 9 in the nozzle position of water level lower limit inductor 10 after, water level lower limit inductor 10 is given controller 13 feedback signals, controller 13 starts entering water electromagnetic valve 4, close drain solenoid valve 6 simultaneously, water in the water supply tank 5 is added in the casing 1 by water inlet pipe 3, both guaranteed the chilling temperature of circulated sprinkling water, and kept stable liquid level in the casing 1, can improve cooling and the typing effect of vacuum sizing case.
