Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of multifunction pump flow control valve.
Background technique
The problem that current plumbing valve exists is: there is no a kind of comprehensive valve, can play electronic, non-return, current limliting, water hammer-resistant, hold effects such as pressing voltage stabilizing, cut-off, if the valve of different functions is installed in a pipe-line system simultaneously, not only do not calculate economically, site environment is being installed, in maintenance, also there is inconvenience, can not meet the requirement of energy-saving and emission-reduction, also greatly increase flow resistance coefficient simultaneously, affect valve normal
Operation.And feature is in the situation that having a power failure, accident power-off termination of pumping, instantaneous exit of pump forms water column and interrupts, suddenly power-off termination of pumping brings water hammer, water hammer collapsing force is now very big, not only can cause water pump high vibration, may allow in addition water pump high speed reverse rotation, cause motor again to start, make rotor permanent deformation or burn out motor.
Model utility content
The utility model will solve the problem that above-mentioned prior art exists, and a kind of multifunction pump flow control valve is provided, reasonable in design, and good airproof performance, powerful.
The utility model solves the technological scheme that its technical problem adopts: this multifunction pump flow control valve, comprise valve body, valve body is provided with water intake and water outlet, and flap is installed in valve body, and flap is connected with valve rod, diaphragm seat is installed on valve body, Packed valve gap is installed on diaphragm seat, the diaphragm that drives stem movement is installed in diaphragm seat, flap comprises main valve clack and secondary flap, secondary flap is fixed on valve rod, and between secondary flap and diaphragm seat, the spring being enclosed within on valve rod is installed; Main valve clack is slidably connected at valve rod outer end, and main valve clack is sealed and matched in the water inlet of valve body, and the O shape circle being sealed and matched on water intake is installed in main valve clack lower end surface; The centre of main valve clack is provided with opening, secondary flap is sealed and matched on opening, between secondary flap and valve rod, seal ring is installed, and secondary flap bottom surface is provided with sealing gasket, sealing gasket is pressed on the bottom surface of secondary flap by fixed plate, the periphery of opening is provided with the ring packing sheet being sealed and matched with sealing gasket.Like this in accident power-off termination of pumping, instantaneous exit of pump forms water column and interrupts, due to the effect of gravity, and main valve clack quick closedown, Slow Close flap is under pressure of return water, and slowly closing, has now formed the two-stage to close.Eliminate like this and the water hammer that has reduced to bring due to the unexpected power-off termination of pumping of accident cause.
For further perfect, telescopic head is installed on valve gap, it is inner and corresponding with valve rod upper end position that valve gap is stretched in telescopic head the inner, and telescopic head outer end is connected with the position limit switch of controlling water pump.Water pump need to shut down while cutting out, first shut electromagnetic valve, and when main valve is closed to a certain degree, position limit switch action switches off the pump, and pressure of return water after this will reduce greatly.
Further perfect, on valve gap, be communicated with conduit, conduit outer end is communicated with three-way valve, and three-way valve is communicated with respectively water intake and water outlet; Pressure gauge and electro-magnetic time-delay valve are installed on conduit.While opening pump, have very large pump start water hammer, may produce larger destruction to water pump downstream line equipment (being water inlet), reduce to open after the effective method of valve water hammer is stablized lift exactly and extend again opening valve time, avoid direct hammer.So need to have at the valve of exit of pump to block with slow, open function, and this valve has increased solenoid valve delay function, opens after pump, after pump head fluctuation is stable, electro-magnetic time-delay valve is opened automatically, and valve is now slowly opened.
Further perfect, pin type stop valve and filter are installed on the conduit between three-way valve and water outlet.
The effect that the utility model is useful is: the utility model multifunction pump flow control valve provides a kind of comprehensive, combines in electronic, non-return, current limliting, water hammer-resistant, holds the valve of pressing voltage stabilizing, cut-off one.And by Slow Close, slow opening, speed is closed, and speed opens that to eliminate the know-why of water hammer integrated, prevents quick closing valve, has a power failure suddenly, and during normal termination of pumping, produces the damage effect of water hammer to pump and other equipment.
