Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As it is shown in figure 1, built-in membrane formula telescoping valve provided by the invention is mainly made up of valve body 7, sleeve lock 11, valve shaft 14, valve seat 8, diaphragm pressing plate 12, diaphragm chamber lid 16, diaphragm 13, spring 9, control assembly, telescoping tube 2 etc.
Sleeve lock 11 is installed on the fixed mount of valve body 7 interior diaphragm chamber and valve shaft 14 is connected, valve seat 8 is installed on valve body 7 outlet end flange place, spring 9 is positioned in the middle of diaphragm plate 19 and sleeve flashboard 18, diaphragm 13 is installed in diaphragm chamber, and middle part is between two diaphragm pressing plate mouths, diaphragm chamber lid 16 and diaphragm plate 19 are harmonious, and control assembly and are installed on the upper end of valve body 7, and telescoping tube 2 is installed on valve body 7 entrance point.
Operation principle is as follows:
Main valve operation principle accepts from controlling component pressure control requirement, once the pressure of back cavity is higher than the pressure of ante-chamber, namely sleeve lock 11 is made to close valve events until closed mode, as shown in Figure 1, otherwise, the pressure of back cavity is lower than the pressure of ante-chamber, and valve opening action namely done by sleeve lock 11 until full-gear, as shown in Figure 2; Then sleeve lock 11 such as front and back two-chamber pressure maintenance poised state is in intermediate equilibria state, as shown in Figure 3.
Embodiment 1:
The present invention can be operated in air relief valve pattern, and as shown in Figure 4, the operation principle of air relief valve is:
Its principle is to control PLC by downstream pressure sensor acquisition pressure signal transmission in remotely, is then carried out control bound by PLC. Once downstream flow strengthens, pressure declines, and sensor signals to PLC, PLC immediate instruction opens solenoid valve B, D at once, and main valve aperture strengthens, the design load that pressure recovers at once, and electromagnetic valve B, D close; Anti-downstream flow reduces, pressure rise then PLC can instruction opens solenoid valve A, C, main valve aperture reduces, the setting value that pressure recovers again, and electromagnetic valve A, C close.
Embodiment 2:
The present invention can be operated in relief valve mode, as it is shown in figure 5, the operation principle of relief valve is:
Its principle is to control PLC by upstream pressure sensor acquisition pressure signal transmission in remotely, is then carried out control bound by PLC. Once system pressure increases to over setting pressure, sensor signals to PLC, PLC immediate instruction opens solenoid valve B, D at once, closes electromagnetic valve A, C, and main valve immediately opens pressure release; Otherwise, system pressure is lower than setting value, then electromagnetic valve B, D are closed in PLC instruction, and opens solenoid valve A, C, main valve is closed.
Embodiment 3:
The present invention can be operated in flow-control valve mode, and as shown in Figure 6, the operation principle of flow control valve is:
Once in remotely after control PLC established standards given flow, the signal Feedback of effusion meter detection is to PLC, as flow has exceeded set-point, then PLC sends signal instruction, open electromagnetic valve A, C (electromagnetic valve B, D close), before diaphragm, cavity pressure declines, and main valve is made to close valve events, then flow reduces to set-point;If flow is lower than set-point, then effusion meter feeds back to PLC signal, then controlling in sends instructions opens electromagnetic valve B, D (electromagnetic valve A, C close), and after diaphragm, cavity pressure declines, and main valve makes breakdown action, supplements flow to set-point.
Fig. 7 is pneumatic control valve piping diagram, is move up and down by a 3 position-5 way electromagnetic valve to control mould diaphragm pressing plate (sleeve) or stop at certain point, and the function of its main valve controls the same with waterpower.
