Description
(1) technical field
The present invention relates to a kind of valve, particularly a kind of for exit of pump, can prevent that medium from flowing backwards, can eliminate water hammer again, can also guarantee the water pump light-load starting, and the valve of energy control valve regulation flow.
(2) background technique
Existing multifunctional water pump control valve, hydraulic butterfly valve, Tiny Drag Slow Shut Check Valves, that the pump discharge valve that generally uses in the present water pump system is used for realizing that non-return, elimination water hammer, underloading open the functions such as pump, but all there are some shortcomings in these several valves, bulky such as multifunctional water pump control valve, valve body structure is complicated, Strike note is too large when closing valve, can not autoshutdown during the pipe network with no pressure and manufacture cost high, especially can not be used for adjust flux; Hydraulic butterfly valve then needs the equipped hydraulic station, and cost is too high, and control system is complicated, and leakage of oil often occurs falls to hammer into shape phenomenon; And Tiny Drag Slow Shut Check Valves can't realize automatically that underloading opens pumping function, need the moving gate valve of other distribution and automatical control system could realize that underloading opens pumping function, weight because of its eccentric valve plate and weight is pressed in above the head again, so resistance coefficient is large, loss of head is very large, energy consumption is too high, and the effect of this valve elimination water hammer is not so good.
(3) summary of the invention
The purpose of this invention is to provide a kind of adjustable automatic cut-off valve, solve the exit of pump valve and have simultaneously check function concurrently, eliminate water hammer function, flow regulating function and the pump valve multi-functional problem that links, and solve the technical barrier problem that the tratitional technology valve mechanisms such as multifunctional water pump control valve, hydraulic butterfly valve, Tiny Drag Slow Shut Check Valves are complicated, cost is high, the life-span is short, energy consumption is high.
Technological scheme of the present invention: this valve mainly is comprised of valve body, eccentric valve plate, valve shaft, double-piston controller, Flow-rate adjustment controller, little Slow Close controller, fork, weight and connection bracket etc.; Valve body adopts the structure of eccentric-butterfly-valve; Eccentric valve plate is fixedly connected with valve shaft, is installed on the valve body by axle sleeve, and eccentric valve plate cylindrical and valve inner sealing seat consist of sealing pair, and eccentric valve plate rotates to realize the switching motion of valve with valve shaft; The double-piston controller is fixedly connected with connection bracket with valve body, double-piston controller and valve shaft, fork is fixedly connected with key pin with valve shaft, the Flow-rate adjustment controller is connected by connection bracket, mounting limit pattern on the output shaft of Flow-rate adjustment controller, the output shaft of Flow-rate adjustment controller and valve shaft are on the same axis, and the position of spacing pattern can be regulated with handwheel.Little Slow Close controller is installed on the valve body inner bottom part, and its Slow Close masthead is lived the block of eccentric valve plate bottom.
When opening water supplying pump, pump discharge has piezodielectric to reach certain pressure, the moment of torsion that acts on the eccentric valve plate is slowly opened valve, because the damping speed limiting function of double-piston controller, can control the opening time of eccentric valve plate, guarantee opening time the opening the pump time greater than water pump of valve, thereby realize that underloading opens the purpose of pump, behind valve opening, the piezodielectric that has in the pipe network enters the double-piston controller by bypass line, and promote continuously the eccentric valve plate of valve shaft by fork and revolve the desired location that opens to spacing pattern, and rely on the pressure stability of pipe network medium to maintain the position of setting, thus realized the purpose of control flow; As the valve opening set positions 90 ° of positions, keep eccentric valve plate at the capable state of levelling downstream, just can guarantee that current are unimpeded smooth-going, avoid producing and stream and whirlpool, keep best hydraulic characteristic, so just can realize the purpose of saving energy and reduce the cost.
When termination of pumping, under the acting in conjunction of the gravity of weight and eccentric valve plate and pressure of return water, the stroke of eccentric valve plate quick closedown 70%, realize that quick non-return prevents the function of water pump reversing, when eccentric valve plate closed to 70% position, the double-piston controller was controlled the closing velocity of eccentric valve plate by damping function, forced the stroke of eccentric valve plate slowly closing 15-20%, avoid so eccentric valve plate to the direct bump of valve body, also realized the function of one-level Slow Close elimination water hammer.
When eccentric valve plate closed to omnidistance 90-95%, the Slow Close masthead of little Slow Close controller was lived the block of eccentric valve plate bottom, has further slowed down the closing velocity of valve, thereby realized the function of secondary Slow Close elimination water hammer.

(5) embodiment
Fig. 1 is the embodiment of adjustable automatic cut-off valve, the eccentric valve plate 2 of this valve is fixedly connected with valve shaft 3, be installed on the valve body 1 by axle sleeve, eccentric valve plate 2 cylindricals and valve body 1 inner sealing seat consist of sealing pair, eccentric valve plate 2 is realized the switching motion of valve with valve shaft 3 rotations, double-piston controller 9 is connected with valve body 1 usefulness connection bracket 4, fork 8 is fixedly connected with valve shaft 3 usefulness key pins, Flow-rate adjustment controller 6 is provided with spacing pattern 5, the position of spacing pattern 5 can be regulated with handwheel, little Slow Close controller 15 is installed on valve body 1 inner bottom part, and its Slow Close masthead is lived the block of eccentric valve plate 2 bottoms.
When opening water supplying pump, pump discharge has piezodielectric to reach certain pressure, the moment of torsion that acts on the eccentric valve plate 2 is slowly opened valve, because the damping speed limiting function of double-piston controller 9, can control the opening time of eccentric valve plate 2, opening time of being guaranteed valve by 13 controls of little safety check opening time opens the pump time greater than water pump, realizes that underloading opens the function of pump; Behind valve opening, the pressure medium continuous action in the pipe network is in double-piston controller 9, promotes continuously valve shaft 3 and eccentric valve plate 2 revolves the desired location that opens to spacing pattern 5, and relies on pipe network pressure medium stable maintenance at desired location; Adjust the position of spacing pattern 5 by the handwheel of adjusting on the Flow-rate adjustment controller 6, open the position thereby adjust revolving of fork 8, and then control the angle of valve shaft 3 and 2 unlatchings of eccentric valve plate, realize the function of Flow-rate adjustment.
During termination of pumping, under the acting in conjunction of weight 10 and eccentric valve plate 2 and pressure of return water, the stroke of eccentric valve plate 2 quick closedowns 70%, automatically the function that reflux medium prevents the water pump reversing is blocked in realization fast, when eccentric valve plate 2 closes to 70% position, double-piston controller 9 is controlled the closing velocity of eccentric valve plate 2 by damping function, force the stroke of eccentric valve plate 2 slowly closing 15-20%, avoided so the direct bump of 2 pairs of valve bodies 1 of eccentric valve plate, also realized the function of one-level Slow Close elimination water hammer, when eccentric valve plate 2 closes to omnidistance 90-95%, the Slow Close masthead of little Slow Close controller 15 is lived the block of eccentric valve plate 2 bottoms, further slowed down the closing velocity of valve, thereby realized the function of secondary Slow Close elimination water hammer, the Slow Close speed of little Slow Close controller 15 and Slow Close time are adjusted by needle-valve 14.
