Description
The utility model is a kind of improved multifunctional water force control valve, belongs to the guiding valve technical field, is particularly useful for the control that water pump is opened and closed.
The water-raising system of water pump generally all is provided with a plurality of valves and effective water hammer cancellation element, and these valves must carry out in the front and back that water pump opens and closes preventing after orderly operation just can make water pump light-load starting or termination of pumping that the pipe-line system medium from flowing backwards and the water hammer accident of pumping system.But it is just very loaded down with trivial details so to work, as is electric operating, very easily initiating failure and cause frequent maintenance.So people are devoted to develop a kind of valve that gathers multi-function in integral whole always.Wherein are no lack of some newly-designed hydraulic control valves, they can play the effect of some safety check and water-hammer arrester to a certain extent, though allow aperture but can automatically control the maximum that to set valve at random, can cause that also slow closing device is malfunctioning if this valve is installed on the pipeline of setting.In addition, adopt diaphragm of rubber usually because these valves are used to eliminate the slow closing device of water hammer accident, so this material is tired easily, wear out, break damage easily and do not have stability, therefore makes complete machine often not reach desirable operational effect.
The purpose of this utility model provides a kind of improved multifunctional water force control valve, this valve has the function of stop valve, safety check, throttle valve and water-hammer arrester etc. concurrently, stable working, durable in use and easy to use, can set valve opening at random with control flow rate.
Solution of the present utility model is, referring to accompanying drawing, a kind of multifunctional water force control valve, it is by valve body (1), valve gap (9), valve seat (13), spool (5), valve plate (7), valve rod (12), spring (11) and comprise modulating valve (2,16), connecting valve (3) is formed in interior assisting agency, wherein valve seat (13) is positioned at advancing of valve body (1), between the water outlet, valve plate (7) is positioned under the valve gap (9) on the valve port, valve rod (12) concentric passes valve plate (7) successively, spool (5) and valve seat (13) and can be in valve plate (7), be free to slide between spool (5) and valve seat (13) center hole, above-mentioned spring (11) is placed in valve rod (12) and goes up its two ends affixed spool (5) and valve plate (7) respectively, advancing of above-mentioned connecting valve (3), water intake and water outlet that don't bother about logical valve body (1) divided at the outlet two ends, improvements are, has a concentric piston cylinder (6) between described valve gap (9) and the valve plate, the piston (8) that can axially be free to slide is arranged in the cylinder, described valve rod (12) passes valve plate (7) towards the other end of spool one end and stretches to piston cylinder (6) the cylinder chamber affixed above-mentioned piston of concentric (8), described modulating valve (2) advances, piston cylinder (6) the upper part cylinder chamber of don't bother about between logical valve body (1) water outlet and valve gap (9) and the piston (8) is divided at the outlet two ends, modulating valve (16) advances, the cylinder chamber, piston cylinder (6) bottom between logical valve body (1) water intake and valve plate (7) and the piston (8) divide is don't bother about at the outlet two ends, concentric correspondence valve rod (12) regulating valve stem (10) that also has been threaded on described in addition valve gap (9) center hole.
The working principle of the utility model multifunctional water force control valve of Gou Chenging is thus, when pump startup, the current that pump by valve body (1) left side water intake flow into valve pocket impact spool (5) pressure spring (11) on the valve seat (13) make spool (5) thus on move Open valve, press water enters cylinder chamber, piston (8) bottom by modulating valve (16) and promotes piston (7) drive valve rod (12) slow spool (5) of opening under controlled speed simultaneously, current flow out through valve body (1) right side water outlet, changeover valve adjustable lever this moment (10) makes it to move down and roof pressure valve rod (12) can promote spool (5) thereby move down to reduce valve opening by valve rod (12), reduces the flow of pump; Otherwise valve rod (12) is up, and valve increases aperture, enlargement discharge, and this valve is easy and simple to handle, and effect is obvious, can reach desirable restriction effect; And after water pump is shut down; water pump water outlet end decompression; cooperate with valve rod (12) spool (5) that slides self gravity and the elastic force effect of spring (11) under quick closedown; and since spool (5) towards the one side decompression of pump and the press water of opposite direction one side enters by modulating valve (2) that cylinder chamber, piston (8) top promotes that piston (8) drives that valve rod (12) is slowly closed spool (5) equally under controlled speed thus by backflow; be quick closedown as above-mentioned spool (5) simultaneously; and the closure between the step ring of spool (5) and valve rod (12) is asynchronous with it; so under the earial drainage effect of spool (5) center hole, can not produce tangible impact of water hammer power so can effectively weaken the water hammer pressure fluctuation; realize the complete machine stable working, prolonged and durable.
Description of drawings.
Shown in the accompanying drawing structural representation of a specific embodiment of the utility model multifunctional water force control valve, wherein:
