Abstract
The utility model discloses a multi-function piston type water pump control valve, which comprises a valve body, a valve base, a valve clack, a guide frame, a valve rod, a guide sleeve, a piston barrel, a valve cover, a guide bar, a spring, an O type circle bolts, a plurality of nuts, a non-return valve, a control valve, a ball valve, and a pressure gauge. The inner of the barrel body is provided with a piston. The differential pressure of the 2 port ends is adjusted by means of a control valve, namely to adjust the opening and closing height of the control valve clack at the piston position. Therefore, the flow rate can be controlled in the control piping. The inner of the piston is provided with a valve rod that is inlaid with an O type circle on the valve clack subassembly. The inner bore at the upper end of the valve rod is provided with a spring and a guide bar which tops the valve cover. The lower end of the valve rod is provided with a valve clack, a guide frame, and an O type circle, and fixed firmly with round nuts. The valve clack and the valve base fit close. Under the spring force, the control valve clack opens slowly and closes quickly. The utility model can control the flow rate, open slowly, close quickly, eliminate water hammer, and prevent media from flowing back; a single valve can reduce the load at the start-up of electric machines, achieving an retrenchment of the equipment and a reduction of the expense.
Description
Technical field: the utility model relates to a kind of being contained on the delivery side of pump, and control flow rate size slow-opening quick-closing is eliminated the water hoop, stops the multi-functional piston formula control valve for water pump that medium flows backwards.
Background technique: existing safety check does not have slow-opening quick-closing and regulates the function of flow size, need be used with gate valve or butterfly valve to lighten the burden could be for electric motor starting the time.
Summary of the invention: the purpose of this utility model provides a kind of gate valve or butterfly valve of not needing and cooperates independent just the use can be the electric motor starting load shedding, all right control flow rate size, and slow-opening quick-closing is eliminated the water hoop, stops the multi-functional piston formula control valve for water pump that medium flows backwards.
Above-mentioned purpose is achieved in that valve seat, cylinder body are contained on the valve body, the valve rod lower end of flap assembly is equipped with flap, leading truck, O type circle and is contained on the valve seat after fastening with round nut, guide sleeve and O type circle are contained on the piston, piston O type circle is contained in the cylinder body, the valve rod of dress edge O type circle in the guide sleeve, shock mount and guide rod in the endoporus of valve rod upper end, valve gap is pressed on the guide rod and with valve body and uses the fastening jail of bolt and nut, refills the ball valve one-way valve and the modulating valve of entrance end pressure gauge and adjusting voltage-stabilizing system.
Working principle: medium enters piston by one-way valve simultaneously and loads promoting flap during primer pump, and the interior gun pressure power of feed-water end pressure and piston is equated, adds flap and can not circulate by the active force medium of spring.Have only modulating valve by regulating system to come the regulating piston pressure that loads to reduce gradually, flap could be opened gradually, and medium could circulate.Thereby reach the slow purpose of opening.Just can reach the purpose of control flow rate size by the pressure difference of modulating valve adjusting inlet and outlet pressure table.When termination of pumping, also we can say when valve import and export pressure at two ends equates,, make it the flap immediate replacement and reach the purpose that speed is closed because flap is subjected to the active force of spring.Piston load be subjected to reflux medium pressure more big valve flap close sternly more, reveal thereby reach O.
The utility model has the advantages that to have the slow-opening quick-closing function, regulate the function of flow size in the pipeline, it does not need the cooperation of other valve just can be the electric motor starting load shedding, has reached the purpose that the equipment of reducing the number of reduces expense.
Description of drawings: Fig. 1 is a sectional drawing of the present utility model.
Embodiment: with reference to Fig. 1, valve seat 23 and cylinder body 7 are contained on the valve body 1, flap 3 and leading truck 2 and O type circle 22 are equipped with in valve rod 4 lower ends on the flap assembly, 24 also are contained on the valve seat with round nut 25 fastening jails, guide sleeve 5 edge O type circles 21 are contained on the piston 16, the piston of edge O type circle 8 is contained in the cylinder body, the valve rod of inlaying O type circle 20 simultaneously is contained in the guide sleeve, valve rod upper end endoporus is loaded onto spring 14 and guide rod 13, edge O type circle 10 is pressed on the guide rod on the valve gap 9, be contained in simultaneously on the valve body also with bolt 11 nuts 12 fastening jails, refill and import and export two ends ball valve 17, ball valve 17 one-way valves 15 modulating valve 16 of pressure gauge 19 and import and export two ends voltage-regulating system.
