Fig. 1 is the formation picture of device of the preferred embodiment of the present invention, includes spool 1, valve body 2.

Fig. 2 is three dimensional structure diagram of the invention.For 45 ° of inclination angle views up and down of the preferred embodiment of the present invention.

Original state and lasting self-styled closed state Fig. 3 of the invention.When original state is anhydrous or a small amount of water, valve body 2 The gravity that the water storage container of bottom utilizes 1 own wt of spool to generate without water or a small amount of water, the present apparatus declines spool 1, The gravity is pressed in the 1 upper, annular conical surface of spool on 2 ring-shaped valve seats of valve body, and spool 1 closes floor drain upper and lower cavity；Present invention dress It sets maintenance and continues self-styled closed state.

Fig. 4 is spool open state of the invention, when the water flow arrival present apparatus leak, as water flow is along apparatus of the present invention The pipeline of valve body 2 flows into the water storage container of 2 bottom of valve body, and the composed structure part of 1 lower part of spool is gradually submerged into water, with valve The volume that core 1 submerges in water gradually increases, and the buoyancy that spool 1 drains is consequently increased, when the buoyancy is greater than spool 1 itself weight Power, buoyancy and the rising of gravity official post spool 1, the 1 upper, annular conical surface of spool disengaging 2 ring-shaped valve seats of valve body, spool 1 and valve body 2 Annular opening is opened, and water flow passes through from the annular opening, is spool open state into drainage pipeline；As long as water flow continues, Water surface elevation in 2 bottom water storage container of valve body can be always maintained at constant, and spool 1 drains production in 2 bottom water storage container of valve body Raw buoyancy also remains unchanged, and makes the annular opening of spool 1 and valve body 2 that can be always held at maximum opening degree.

Fig. 3 also shows the state that workflow terminates, when water flow stops, body base water storage container without discharge opening, Water surface elevation is continued in valve channel height, and spool 1 is submerged into the constancy of volume in water, spool still in open state, The height of valve body water storage container bottommost to valve body drainage channel is full of water, i.e., water is full of at annular opening, at this moment water seal closed loop Shape opening is water seal closed state；With the evaporation of dampening, water surface elevation drops to a certain height, the buoyancy that spool draining generates by Decrescence as low as buoyancy is less than 1 self gravity of spool, and gravity and buoyancy official post spool 1 decline, and the 1 upper, annular conical surface of spool is pressed in valve On 2 ring-shaped valve seats of body, annular opening closes floor drain upper and lower cavity, and water is then gradually evaporated to nothing, returns to primary gravity of the invention Self-styled closed state.

Fig. 5 shows counnter attack and gushes function；When drainage pipeline generates abnormal waste water fluid stream, which is more than indoor ( Leak epicoele) pressure, waste water fluid stream is redirected back into floor drain epicoele by floor drain from floor drain cavity of resorption, as pipeline it is counter emerge in large numbers as, due to For the waste water fluid stream through floor drain annular opening to indoor (floor drain epicoele) flowing, flowing the hydraulic power generated at annular opening makes valve Core is intended to close, and anti-drainage pipeline pressure when gushing is greater than indoor (floor drain epicoele)) pressure, also close spool, spool is automatic Closing prevents that the waste water fluid stream of drainage pipeline from being entered the room by floor drain or function is gushed in ground, as counnter attack；Since floor drain is automatic Closing, drainage pipeline waste water fluid stream pressure will act directly on floor drain forced area, and the installation as the pressure is greater than floor drain is locked When clamp force, even if floor drain is automatically closed counnter attack and gushes function normal work, floor drain will also be washed out by waste water fluid stream pressure and lose work With.
