Abstract
The utility model relates to a vacuum pressure-release early warning device, which comprises at least two vacuum pipelines, wherein the two vacuum pipelines are respectively connected with one pressure display correspondingly, and each pressure display is connected with an integrated alarm control box via a data transmission line. The vacuum pressure-release early warning device has the advantages that the early warning device is a system capable of monitoring vacuum degree of different areas at any time and making early warning for areas with local pressure release lower than the requirement of the vacuum degree, and can effectively eliminate affection onto product quality caused by lagging and relieve tension of inspection personnel.
Description
Technical field
The utility model relates to vacuum line negative pressure control field, relates in particular to a kind of circuit module of vacuum release prior-warning device.
Background technology
MW class wind turbine blade is large-scale expoxy glass steelwork, enterprise produces the main vacuum infusion molding technology that adopts, whole technological process has strict requirement to the lasting vacuum tightness of each vacuum line, if vacuum tightness is lower than certain numerical value, product generation mass defect possibility very big.
Show the vacuum tightness that adopts several vacuum meters to show zones of different respectively in the prior art, and arrange the professional to patrol and examine, regularly several vacuum gauge pressure values are monitored, because operating personnel can not monitor several zones at any time, cause the local depression vacuum in time not found, the hysteresis quality of this outwardness causes great hidden danger to the quality control of product, also makes operating personnel's high-pressure at any time simultaneously.
Summary of the invention
The utility model technical issues that need to address have provided a kind of vacuum release prior-warning device, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: at least two vacuum lines; Described at least two vacuum lines are continuous with a corresponding pressure display unit respectively; Each pressure display unit links to each other with the integrated alarms control box by data line.
Compared with prior art, the beneficial effects of the utility model are: can monitor each regional vacuum tightness at any time, and local release is lower than the system that in time reports to the police in zone that vacuum tightness requires; The influence of hysteresis quality can be effectively solved, and the personnel's of patrolling and examining buck fever can be discharged product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: at least two vacuum lines 10; Described at least one vacuum line 10 is continuous with a corresponding pressure display unit 1 respectively; Each pressure display unit 1 links to each other with integrated alarms control box 3 by data line 2;
On described data line 2, also comprise one with integrated alarms control box 3 in show the corresponding line switching 4 of low pressure line;
It is by a flexible pipe 5 that described vacuum line 10 links to each other with pressure display unit 1; Between end of flexible pipe 5 and pressure display unit 1, also connect flexible pipe ball valve 6.
Pressure display unit in the utility model (pressure transducer) is to be connected with a vacuum line by connecting each pressure display unit of flexible pipe, top liquid crystal digital display meter shows the pipeline negative pressure, two safety values in bottom are provided with button, and digital display negative pressure value and safety value comparison signal are passed to the integrated alarms case.
The power supply of the direct controlled pressure display of line switching connects, and when a plurality of comparison signals cause warning, can make by line switching only to show a low pressure line at every turn, can carry out malfunction elimination one by one.
Pipeline connects flexible pipe, connects the flexible pipe ball valve in the utility model:
Flexible pipe one end is connected with vacuum line, and the other end is connected with pressure display unit, the vacuum line negative pressure signal can be directly passed to the pressure sensing original paper and carry out reading.If pressure display unit self damages and to cause gas leakage, influence line pressure and control, can close between the two connection by the flexible pipe ball valve.
Each data lines one end of data line is fixedlyed connected with a pressure display unit, and other end fast interface links to each other with a rapid-acting coupling of integrated alarms case side.The comparison signal of each pressure display unit can be passed to the integrated alarms case by several data lines.
Integrated alarms control box in the utility model:
If it is normal that certain comparison signal is shown as line pressure, then its corresponding green light button lights.If each line pressure is all normal, then alarm gives a green light, alarm free sound.Otherwise if a certain line pressure is low excessively, then the corresponding red light button in green light button below lights, and alarm sends out a warning simultaneously, alarm sounds sound, and control box is with two buttons of opening and closing.
The utility model preestablishes the lower safety limit value to each zone, and each regional force value of digital display at any time, in case certain regional digital display force value is lower than safe preset value, the warning horn of respective regions sounds, patrol and examine personnel and can know it is that certain regional pressure descends immediately by warning horn, can take corresponding measure rapidly, the influence that has effectively prevented the hysteresis of measure that product quality is caused.
Use main points of the present utility model are as follows:
1, preestablish the minimum pressure alarming value on pressure display unit, the impermeability of preoperation inspection interface is inserted supply socket with plug during use, energized.
2, know the corresponding fast interface of each pressure display unit on the integrated alarms case, color indication button, indicated pressurize pipeline.Several red button and several the green button vertical directions are corresponding one by one on the integrated case, indicate a pipeline respectively.
3, sound as chimes of doom, check electronic box indication button immediately, its corresponding pipeline pressure value of the bright expression of red button is low, should take corresponding pressurize measure.Do not stop if warning horn rings always,, can close the connection of this circuit for preventing to influence other pipeline indications.After treating thoroughly to have looked into pressure-retaining system, can open this circuit again and connect.
4, guarantee that vacuum release early warning system pipeline is unimpeded, will check whether whether pipeline stops up, influence the result after each the use.
