Abstract
The utility model discloses an overflow protection valve which essentially consists of a valve body, a floating ball and a shifter lever. The valve body is a column-shaped direct-current channel. The vertical direction with the direct-current channel is provided with a through hole which forms a converse T-shaped interval channel with the direct-current channel. The upper of the through hole is covered with a sealing pressing cover. The inner cavity of the valve body is provided with the floating ball. The inner wall of drainage side of the direct-current channel is provided with a half ball-shaped valve opening with inosculate size. The direct-current channel tube wall of the drainage side is provided with a long groove which has a shifter lever and the groove is sealed by a glue mat and a pressing cover. The two ends of the direct-current channel are provided with a thread which is connected with a tap water pipeline. The overflow protection valve of the utility model adopts the impulsive force, pressure and buoyancy of water and the shifter lever to position the floating ball at different positions to achieve the aim of preventing water from overflowing. The utility model has the advantages of simple structure, low cost, convenient utilization and good protection effect to overflow of water pipe.
Description
Technical field
The utility model belongs to the technical field of pipe valve, is specifically related to a kind of Self-closed water valve.
Background technique
Existing building usually supplies water on time, does not close water tap when the user cuts off the water, and after resuming water supply, water is full excessive, and waste water resource also brings disaster to neighbours, results in hand cramps to the resident.
Summary of the invention
The purpose of this utility model is to provide a kind of Overflow protection valve, prevents that current are excessive, has water-saving function simultaneously.
The technical solution of the utility model is: Overflow protection valve is made up of valve body, ball float and driving lever, valve body is the cylindrical straight circulation road, one side is a water intake, one side is a drain opening, with the perpendicular direction of direct current channel one through hole is arranged, this through hole and direct current channel constitute inverse-T-shaped runner, and the through hole upper end is covered with sealing gland; Body cavity is provided with ball float, and direct current channel is intake side pipe footpath less than floating ball diameter, and direct current channel draining one side inwall is provided with the hemisphere valve port, coincide with the ball float size of body cavity, have elongated slot on the direct current channel tube wall of draining one side, a driving lever is set in the groove, groove is by rubber cushion, gland seal; The direct current channel two ends is provided with screw thread, is connected with water supply pipe.
The utility model Overflow protection valve is installed on the domestic running water main pipe, utilizes impulse force, pressure, buoyancy and the driving lever of water to make ball float be in different positions, to reach the anti-excessive purpose of sealing.When pipeline came water, the impulse force of water was shifted the ball float that is provided with in the valve body onto hemisphere type valve port place, because stopping of tube wall can not be floated ball float, seal for pipe joints stops the current piping.If during water, to stir driving lever and make ball float move on to the through hole of valve body, ball float floats, and water normally passes through valve.The valve body direct current channel is intake the caliber of a side less than floating ball diameter, prevents that ball float from entering the feed-water end of valve body.
The utility model is simple in structure, and cost is low, and is easy to use, and the water pipe spilling water is had protective action preferably.
