Abstract
The utility model provides a step-in high-temperature damp-heat test box, which comprises a water tank and a water injection pipe, which are installed inside the step-in high-temperature damp-heat test box, wherein the water injection pipe is provided with a valve, the water tank is provided with a first electrode and a second electrode for monitoring water level, the first electrode and the second electrode are insulated to the water tank, and the first electrode and the second electrode are also connected with a controller for receiving and processing a water level signal and controlling a valve. The step-in high-temperature damp-heat test box is characterized in that a natural attribute that water is electrically conductive is utilized, the wall of the water tank is provided with two electrodes, one of the two electrodes are set at a preset water level value, when the water is over the electrode, and the two electrodes are conducted, the controller can control the valve to open and close after receiving the signal, so that a system for controlling the water level of the water tank is simple in structure, free from multiple mechanical links, long in service life, difficult to damage, accurate in monitored water level data and good in control effect.
Description
Technical field
The utility model relates to a kind of temperature control testing equipment, relates in particular to the chamber of a kind of walk-in type high temperature wet-hot type.
Background technology
The chamber of walk-in type high temperature wet-hot type has another name called environmental test chamber, can simulate exactly low temperature, high temperature, hot and humid, the natural shape environment that low temperature and low humidity etc. are complicated, be applicable to plastic cement, electronics, food, clothes, vehicle, metal, chemistry, the product reliability of the multiple industry such as building materials detects, existing height is asked alternating temperature humidity test chamber normal operation ball float and is connected to the ball float tail end keeps water tank for the control device of control water filling switch water level, the device of this control water level in use for some time, coupling part between ball float and control device produces fracture easily, corrosion or card pause, cause water level monitoring inaccurate, in time water filling or after reaching warning line, can not stop water filling, thus whole device fails caused.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the weak point in service life of the cistern water level monitor controller that has the chamber of walk-in type high temperature wet-hot type now, the problem that fault rate is high, the utility model provide the chamber of a kind of walk-in type high temperature wet-hot type to adopt new water level monitoring control device to solve the problems referred to above.
The technical scheme that its technical problem that solves the utility model adopts is: the chamber of a kind of walk-in type high temperature wet-hot type, comprise the water tank and the water injection pipe that are installed in the chamber of walk-in type high temperature wet-hot type, be provided with valve on the described water injection pipe, the first electrode and the second electrode for the monitoring water level are installed on the described water tank, described the first electrode and the second electrode and water tank insulation, described the first electrode and the second electrode also are connected with the controller for reception ﹠ disposal water level signal and by-pass valve control.
In order accurately to monitor water level signal, described the first electrode and the second electrode stretch into water tank inside.
Further, the setting height(from bottom) of described the first electrode is the preset water level value, and described the second electrode is installed in water tank bottom.
In order to prevent that the first electrode and the second electrode from directly by the tank wall conducting, causing to monitor wrong water level signal, the tank wall of described water tank is that insulator or inside and outside wall scribble insulating materials.
The beneficial effects of the utility model are, the chamber of this walk-in type high temperature wet-hot type utilizes water can conduct electricity this natural attribute, tank wall at water tank arranges two electrodes, one of them electrode is arranged on predefined water level value, when water covers this electrode, two just energy conductings of electrode, controller receives the switch that signal just can by-pass valve control so, a kind of like this control system structure to cistern water level is simplified, without too much mechanical link, long service life, not fragile, and the waterlevel data of monitoring is accurate, controls effective.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the optimum embodiment of the utility model walk-in type high temperature wet-hot type chamber.
Among the figure 1, water tank, 2, water injection pipe, 3, valve, the 4, first electrode, the 5, second electrode, 6, controller.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model provides the chamber of a kind of walk-in type high temperature wet-hot type, comprise the water tank 1 and the water injection pipe 2 that are installed in the chamber of walk-in type high temperature wet-hot type, be provided with valve 3 on the water injection pipe 2, the first electrode 4 and the second electrode 5 for the monitoring water level are installed on the water tank 1, the first electrode 4 and the second electrode 5 and water tank 1 insulation, the first electrode 4 and the second electrode 5 also are connected with the controller 6 for reception ﹠ disposal water level signal and by-pass valve control, the first electrode 4 and the second electrode 5 stretch into water tank 1 inside, the setting height(from bottom) of the first electrode 4 is the preset water level value, and the second electrode 5 is installed in water tank bottom.
When the beginning water filling, because the location comparison that the second electrode 5 is installed is low, water can cover first the second electrode 5 at the beginning, water level temporarily can't reach the position that the first electrode 4 is installed, because tank wall is insulating materials, not conducting between the first electrode 4 and the second electrode 5, valve 3 is in open mode, after a few minutes, water level is raised to the height of the first electrode 4, and water covers the first electrode 4, the first electrode 4 and the second electrode 5 utilize the electric conductivity conducting of water, controller 6 receives level signal, and by-pass valve control 3 is closed, and stops water filling.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
