Check valve core sealed by mechanical and magnetic force

Abstract

The invention provides a check valve core sealed by mechanical and magnetic force, which consists of a check valve core main body, a movable gate and a balance weight. Magnetic force acts between the check valve core main body and the movable gate, the opened movable gate is gradually closed by the balance weight, and a water outlet of the check valve core is sealed by the movable gate under the action of magnetic force. The check valve core sealed by mechanical and magnetic force is opened and closed through the variation of water flow entering the check valve core. The check valve core sealed by mechanical and magnetic force has the advantages of small volume, rapid opening and closing, large water draining capability, good seal effect, strong self-clearing capability, simple structure, low manufacture cost, convenience for use and maintenance and the like.

Description

technical field [0001] The invention relates to a one-way valve core, in particular to a mechanical magnetic seal one-way valve core. Background technique [0002] As an important device in the drainage system, the one-way valve of the drainage pipe plays an important role in building drainage. The one-way valve of the drainage pipe should have two basic functions: one is smooth drainage, which can quickly remove water from water appliances and drainage pipes; the other is good sealing performance, which can effectively prevent the odor in the sewer pipe from entering the room. The existing one-way valves in drainage pipes are generally replaced by water traps. The common problems of water traps are mainly manifested in: ①The water seal of the water trap is easy to lose its sealing effect due to insufficient height or the water is evaporated; ②Water trap The drainage capacity of the trap is weak, and it is prone to poor drainage; ③The self-cleaning ability of the trap is po...

The existing one-way valves in drainage pipes are generally replaced by water traps. The common problems of water traps are mainly manifested in: ①The water seal of the water trap is easy to lose its sealing effect due to insufficient height or the water is evaporated; ②Water trap The drainage capacity of the trap is weak, and it is prone to poor drainage; ③The self-cleaning ability of the trap is poor, and it is easy to deposit hair and sludge to form a blockage; The resulting positive or negative pressure destroys the
