The invention discloses a linkage device of a water pump and a water outlet valve of the water pump. The linkage device comprises a cavity, a stepper motor and the water pump; a connecting valve is arranged in front of the cavity; a conveying pipe is arranged below the cavity; a flow valve is arranged at one end of the conveying pipe; a front pressing block is arranged in the cavity; a buffer spring is arranged behind the front pressing block; a back pressing block is arranged behind the buffer spring; a contact switch is arranged behind the back pressing block; a connecting frame is arranged behind the contact switch; the stepper motor is arranged below the connecting frame; a ball screw is arranged below the stepper motor; a follow-up valve is arranged below the ball screw; upper limit photoelectricity is arranged at the upper end of the ball screw; and lower limit photoelectricity is arranged at the lower end of the ball screw. The device achieves excellent linkage effect between the water pump and the valve, in addition, has the advantages of stable action structure and consistency of all parts, and is convenient to use and low in production cost.
Description
technical field [0001] The invention relates to the design field of water pump linkage equipment, in particular to a linkage device of a water pump and a water outlet valve of the water pump. Background technique [0002] Centrifugal pumps in our country started from imitating Soviet products in the 1950s. At that time, only K-type single-stage single-suction cantilever centrifugal water pumps and convex single-stage double-suction centrifugal water pumps supported at both ends were produced, which were mainly used for irrigation and drainage of farmland. In the 1960s, my country designed and developed a series of domestic centrifugal pumps; the clean water pump was changed from K type to B type, and the convex type was changed to SH type; the petrochemical industry was changed from DJ, SJ, FSJ. Type, FL, BN type is changed to F type; boiler feed water pump also produces DH type, etc., which meet the requirements of most domestic devices. The current technical level of domes...
