Abstract
The utility model discloses a multifunctional water pump control valve, which comprises a valve body. A valve cover is arranged on the valve body, a through hole is positioned on the valve cover, a piston rod penetrates through the through hole, and a sealing ring is arranged between the piston rod and the through hole. The bottom end of the piston rod is connected with a valve plate, a spring is sleeved on the piston rod, and two ends of the spring are respectively in elastic contact with the valve cover and the valve plate. An annular step is arranged on the lower surface of the valve plate which is wrapped with a sealing sheet, a through hole is arranged in the center of the valve plate, and the lower end of the piston rod is connected with a guide rod and penetrates through the through hole on the valve plate. A valve body wall is connected with a guide plate, a guide hole is positioned on the guide plate, and the guide rod at the lower end of the piston rod penetrates through the guide hole. The multifunctional water pump control valve is good in sealing performance, can effectively prevent media from flowing back and avoids water hammer and water attack.
Description
Technical field:
The utility model relates to valve field, and concrete is a kind of multifunctional water pump control valve.
Background technique:
Multifunctional water pump control valve is mounted in the pump outlet place of large-caliber water supply pipe network system, prevents the intelligent type valve of the phenomenon of medium refluence, water hammer and water attack.In order to realize the automation of water pump operation; Streamlining management; Lighten one's labor, improve reliability, people replace manually-operated gate with waterpower valve and electric valve; Monomer valve is carried out multinomial technological improvement, novel valves such as slow open and close check valve, slow-action keying waterpower valve, automatic Slow Close gate valve, double speed self closing stop valve occurred.Gate valve is to be in closed condition at ordinary times, and gate valve is slowly opened during starting mode of pump, and when water pump was shut down, gate valve was slowly closed earlier.Closing the lock startup and closing lock of water pump stopped, and can effectively prevent turn on pump water hammer and pump-stopping water hammer, and simultaneously, the motor load when having reduced starting mode of pump, the water pump air horsepower when zero delivery is minimum, generally is merely 30% of design air horsepower.Another function of gate valve is, when gate valve is closed, can safe maintenance condition be provided for being installed in valve member such as check valve between gate valve and the water pump and water pump, prevents that the water of pressure supply water pipe from refluxing.
The model utility content:
The utility model provides a kind of multifunctional water pump control valve that can prevent the phenomenon of medium refluence, water hammer and water attack.
The technological scheme of the utility model:
Multifunctional water pump control valve comprises valve body, and valve body is provided with valve gap; It is characterized in that: described valve gap is provided with through hole, is installed with piston rod in the through hole, is provided with seal ring between piston rod and the through hole; Described piston rod bottom connects valve plate; Described upper cover of piston rod has spring, and Elastic Contact is on valve gap and valve plate respectively for described both ends of the spring, and described valve plate lower surface is provided with ring-shaped step and is coated with diaphragm seal; Described valve plate central authorities are provided with through hole, and described piston-rod lower end connects guide rod and also passes the through hole on the valve plate.
Described multifunctional water pump control valve is characterized in that: be connected with guide plate on the described valve body wall, described guide plate is provided with pilot hole, and the guide rod of described piston-rod lower end passes described pilot hole.
The advantage of the utility model:
The utility model good airproof performance, can effectively prevent medium refluence, water hammer and water attack phenomenon generation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the partial enlarged drawing of the utility model valve plate sealing part.
