Abstract
The utility model discloses a mute type check valve, which comprises a cylindrical valve body. A water inlet is arranged at one end of the valve body, a water outlet is arranged at the other end of the valve body, a valve seat is fixedly arranged in the valve body, a connection plate is connected between the valve seat and the water outlet, a valve rod facing the water inlet is arranged in the valve seat, a valve clack matched with the water inlet is sleeved on the valve rod in sliding mode, and a spring is arranged between the valve clack and the valve seat. The mute type check valve is reasonable in structural design, balanced and stable in operation, free of noise and less in safety hazards no matter how the pressure of a medium at the inlet end changes.
Description
Technical field
The utility model relates to field of check valves, specifically belongs to the squelch type safety check.
Background technique
The squelch type safety check is meant and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims check valve, one-way valve, reflux valve and back pressure valve again.Safety check belongs to a kind of automatic valve, and it mainly acts on is to prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media.But present squelch type check valve structure is too complicated, and product is heavy, and fabricating cost is high.
The model utility content
The purpose of the utility model provides a kind of squelch type safety check, reasonable in design, and regardless of the pressure medium variation of entrance point, operation balance and stability, and noise free, safe failure is few.
The squelch type safety check includes the valve body of tubular, and an end of valve body is a water intake; The other end is a water outlet; The valve body internal fixation is provided with valve seat, is connected with connecting plate between valve seat and the water outlet, is provided with the valve rod towards water intake in the valve seat; Flip sleeve is equipped with the flap that is complementary with water intake on the valve rod, is equipped with spring between flap and the valve seat.
Described flap is cone, and cone is matched with in the water intake.
When the utility model flowed by prescribed direction when medium, flap received the effect of medium power, is unlocked; During medium counter flow,, make the sealing surface driving fit of flap and valve seat and close, reach the purpose of prevention medium counter flow because of flap deadweight and flap receive the effect of medium opposite force.Because the open and close of flap is to be in the dynamic equilibrium of forces system, change regardless of the pressure medium of entrance point, operation balance and stability, and noise free, safe failure is few.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, the squelch type safety check includes the valve body 1 of tubular; One end of valve body 1 is a water intake 2, and the other end is a water outlet 3, and the valve body internal fixation is provided with valve seat 4; Be connected with connecting plate 5 between valve seat 4 and the water outlet, be provided with the valve rod 6 towards water intake in the valve seat 4, flip sleeve is equipped with the flap 7 that is complementary with water intake on the valve rod 6; Flap 7 is cone, and cone is matched with in the water intake, is equipped with spring 8 between flap and the valve seat.
