Fig. 1 is the utility model structural representation.
Among the figure, valve body 1, main valve plate panel seat 2, main valve plate 3, Slow Close valve plate 4, valve rod 5, valve block seat 6, lining 7, valve block 8, valve block pressing plate 9, valve gap 10, go out water regulating valve 11, the water inlet modulating valve 12
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of new type auto control valve for water pump comprises valve body 1, valve plate seat 2, valve plate 3, switching valve plate 4, valve rod 5, valve block seat 5, pad 7, valve block 8, valve block pressing plate 9, valve gap 10, goes out water regulating valve 11, water inlet modulating valve 12; The valve rod 5 that arranges in the described valve body 1 is with valve plate 3, open and close valve plate 4, pad 7, valve block 8, valve block pressing plate 9 links together, pad 7, valve block 8, valve block pressing plate 9 is arranged on valve body 1 upper end inner chamber, valve body 1 top is provided with valve gap 10, valve block 8 is arranged between valve gap 10 and the valve block seat 5, linking together with switching valve plate 4 of valve block 8, valve rod 5 passes the center hole of valve plate 3, valve plate 3 can slide along valve rod 5 in certain scope, be pressed on the valve plate seat 2 under the pressure of valve plate 3 by holddown spring, be provided with out water regulating valve 11 in the both sides of valve block seat 6, water inlet modulating valve 12, below valve block pressing plate 9, be provided with valve block 8, water inlet modulating valve 12 is connected with valve block 8 epicoeles, goes out water regulating valve 11 and is connected with valve block 8 cavity of resorptions.
The automatic pump control valve is a kind of hydraulic control valve door, the alternative mortor operated valve of one valve, safety check and three kinds of devices of water-hammer arrester, slow opening when it can realize turn on pump automatically, speed during termination of pumping is closed and Slow Close, need not any electrical control and other power and manpower, also need not oil gear, its workmanship's principle is: before the starting mode of pump, the pressure water action of valve export end is on the main valve plate, and valve is in closed condition; During starting mode of pump, valve can not opened at once, has only after pressure reaches certain value, and press water just can carry out the diaphragm controller cavity of resorption from bypass tube, promotes valve block pressing plate 9, drive valve rod 5 and open and close valve plate 4 to rise together, thus protection water pump light-load starting.
Because control valve for water pump has two valve plates, the main valve plate valve plate that eases up.Valve plate 3 is that sky is enclosed within on the valve rod 5 by the current picking-up.During termination of pumping, current slow down, and valve plate 3 glides rapidly under the effect of self gravitation.When current are close to zero, close, realize the fast generation that prevents the water hammer ripple of closing, on 3 valve plates discharge orifice is arranged simultaneously, allow sub-fraction water to reflux, the front and back of valve form pressure difference, the pressure of outlet end is higher than entrance point, the high pressure water of outlet end enters the epicoele in valve block 8 control rooms by bypass tube, promoting valve block pressing plate 9 drives valve rod 5 and opens and closes valve plate 4 together, discharge orifice on the valve plate 3 is slowly closed, thereby realize eliminating issuable water hammer, the whole service process of automatic type control valve for water pump all is to utilize the pressure difference of valve front and back to realize, so it has: 1, need not operation control, the differential water pressures when utilizing the water pump start and stop before and after the valve is as control power, function with automatic on-off with the keying of water pump is eliminated artificial fully, the misoperation that equipment etc. cause; 2, the valve opening and closing course of action can be effectively because preventing the rising of water hammer pressure ripple, and according to on-the-spot use condition investigation and actual measurement, the pump-stopping water hammer pressure peak is all in 1.3 times of working pressure; 3, need not field adjustable, applied widely; 4, need not maintenance substantially, because it is simple in structure, a valve substitutes three valves, and the maintenance and repair workload significantly reduces; 5, drag losses is little; 6, adopt streamlined, wide valve body design.
Before the starting mode of pump; the valve export end pressure acts on the valve plate 3; valve plate 3 is in the closed position; the epicoele of valve block 8 is communicated with press water simultaneously; cavity of resorption then communicates with water inlet modulating valve 12 low pressure of valve inlet end; behind the starting mode of pump; valve inlet pressure raises gradually; press water slowly enters valve block 8 cavity of resorptions by water inlet modulating valve 12 connecting tubes of valve inlet end simultaneously; realize the slow unlatching of valve plate 3; when water pump is shut down; the pressure of valve inlet reduces, and when near zero delivery, valve plate 3 is closed rapidly under the self gravitation effect; because the valve inlet end pressure reduces; the press water of valve export end enters the diaphragm controller epicoele by connecting tube, and cavity of resorption water pushes back to the valve inlet end by the connecting tube of valve inlet end, opens and closes valve plate 4 and slowly closes; the Slow Close that valve plate 4 was closed and opened and closed to the speed of valve plate 3 meets two stage Closing Law of water system, so can subdue the water hammer pressure peak value effectively.Slow opening in the time of realizing turn on pump, the Slow Close during termination of pumping prevents the generation of water hammer accident effectively, but it does not have any electrical control power or external force pressurized oil system, has also adopted wide valve body flow pattern design in the valve body design, has reduced resistance to water-flow effectively.
