Above-mentioned said small trimmer valve has individual valve seat, and spool is installed in valve seat, and seal ring is installed on the spool, and adjustable cap also is installed on valve seat, and spring seat is installed on adjustable cap, between spring seat and spool spring is installed.
Above-mentioned said modulating valve has a valve seat, and spool is installed in valve seat, and seal ring and locking nut are installed on the spool.
The utility model compared with prior art has following advantage:
1. owing between valve body and valve gap, buffering hydraulic cylinder has been installed, processed water conservancy diversion water channel and pressure release water channel in the both sides of valve body, buffering hydraulic cylinder and valve gap, therefore, can effectively stop the backflow of water, eliminated of the impact of water hammer wave pressure water pump vane.
2. on valve body and valve gap, be separately installed with speed and close device and disabling mechanism, not only have the dual functions of safety check and stop valve, and compact structure, material saved.
3. the versatile interface that is connected with the water conservancy diversion water channel is installed on buffering hydraulic cylinder, shortens and simplified water system, simultaneously, also be convenient to the automatic control of water pump.
Provide embodiment of the present utility model below in conjunction with accompanying drawing
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
As shown in drawings, the utility model has a valve body 1 and valve gap 9, and main valve plate disabling mechanism is installed on valve gap 9, and described disabling mechanism is made up of handwheel 6 and valve rod 7, is equipped with to prevent the seal ring 10 that leaks on valve rod 7; Between valve body 1 and valve gap 9, buffering hydraulic cylinder 4 is installed, speed is installed in buffering hydraulic cylinder 4 and valve body 1 closes device, described speed is closed device a piston 17, piston 17 is positioned at buffering hydraulic cylinder 4, the piston rod 18 of piston 17 bottoms extend in the valve body 1, main valve plate 20 is installed in the above, main valve plate 20 adopts soft sealing structure, to improve sealing and buffering effect, between main valve plate 20 and buffering oil hydraulic cylinder 4, spring 19 is installed, making speed close device closes rapidly when termination of pumping, side at valve body 1 and buffering oil hydraulic cylinder 4 is processed with water conservancy diversion water channel 2, water conservancy diversion water channel 2 makes the space below the piston 17 be connected with the feed-water end of valve body 1, on valve gap 9, be processed with pressure release water channel 8, pressure release water channel 8 makes the space above the piston 17 be connected with water conservancy diversion water channel 2, on the valve gap 9 that pressure release water channel 8 and water conservancy diversion water channel 2 cross, small trimmer valve is installed, described small trimmer valve has a valve seat 5, the spool 24 of conical sealing surface is installed in valve seat 5, seal ring 25 is installed on spool 24, adjustable cap 21 also is installed on valve seat 5, spring seat 22 is installed on the center hole of adjustable cap 21, between spring seat 22 and spool 24, holddown spring 23 is installed; Opposite side at valve body 1, buffering hydraulic cylinder 4 and valve gap 9 is processed with water conservancy diversion water channel 11, water conservancy diversion water channel 11 makes the space above the piston 17 be connected with the waterexit end of valve body 1, on the water conservancy diversion water channel 11 of valve gap 9, flow control valve is installed, described modulating valve has a valve seat 12, spool 15 is installed in valve seat 12, seal ring 16 and locking nut 14 are installed on spool 15, dust cover 13 also is installed on valve seat 12; The versatile interface 3 that is connected with water conservancy diversion water channel 2 also is installed on buffering hydraulic cylinder 4.
During pump working, the handwheel 6 of disabling mechanism is threaded to the extreme higher position, current will upwards promote main valve plate 20, simultaneously, another part water enters the space of buffering hydraulic cylinder 4, piston 17 bottoms through water conservancy diversion water channel 2, and at this moment, piston 17 and main valve plate 20 rise rapidly under hydraulic action, main valve plate 20 is opened, and pressure flow flows into pipe network system; When water pump stopped operating for some reason, piston 17 and main valve plate 20 bottom decompressions under the effect of spring 19, were depressed main valve plate 20, and sealing main valve passage has played the effect of safety check; When reverse flow arrives, the piston 17 that moves downward attracts the part current, enter respectively in buffering hydraulic cylinder 4 and the pressure release water channel 8 through water conservancy diversion water channel 11 and flow control valve, enter also accelerating piston 17 declines of current in the buffering hydraulic cylinder 4, close the main valve passage, along with closing of main valve passage, the water hammer wave pressure is also raising, at this moment, the current that enter into piston 17 upper spaces are through pressure release water channel 8, small trimmer valve and water conservancy diversion water channel 2 flow into the feed-water end of valve body 1, enter water pump, like this, the part current of venting can make the interior water attack of valve be alleviated rapidly, the water that enters water pump is also because flow is very little, and the water pump basal area is bigger again, therefore, can not promote the water pump vane counter-rotating, damage water pump vane.
When water pump need not turn round, handwheel 6 can be rotated down, make valve rod 7 withstand piston 17, close the current main passage.
