Abstract

The utility model relates to a water discharge valve of a flexible valve seat used in a flush toilet, which is characterized in that a flexible valve seat is added on a water discharge pipe opening, the surface contact of a valve sheet and the valve seat is converted into spherical surface contact or conical surface contact, and the sealing property of the water discharge valve is enhanced by the full utilization of elastic force of a valve seat lip part, self-gravity of the valve sheet, transient water hammer force, and static pressure of water to prevent the water leakage of a cistern. The utility model has the advantages of simple structure, high safety, and good tightness. The utility model is suitable for being popularized and used in various flush toilets as well as other high position quantity cisterns.

Description

The flexible valve seat draining valve of flush toilet

The utility model relates to the employed flushing valve in a kind of fixed buildings watering privy, the flexible valve seat draining valve that particularly a kind of toilet flush is used.

The present flush toilet draining valve that uses, be that flexible rubber sealing valve block is installed on the draining mouth of pipe of hard, its sealing performance is subjected to factor affecting such as contact surface size, planeness, elastic deformation, suffered water pressure, but owing to limit by material and machining accuracy, particularly the valve block of plane contact easily produces permanent deformation, the water discharging valve sealing performance is descended, the radiator leak phenomenon is obvious, easy-maintaining not, cause water resource waste, flush the toilet malfunctioning, excess surface water and influence the sanitation of environment of rest room.

The purpose of this utility model is to overcome above-mentioned weak point and provide a kind of flush toilet flexible valve seat draining valve, it is to increase a flexible valve seat on the toilet flush draining mouth of pipe, valve block is changed into sphere with the plane contact of valve seat or the conical surface contacts, make full use of valve block deadweight, moment water hammer power and the static pressure of water tank improve the sealing performance of draining valve, thereby prevent radiator leak, the conserve water resource is improved the sanitary condition of rest room.

The purpose of this utility model can reach by following measure: this draining valve is by the draining knob, lever, stay cord, valve block, gutter, bleed off pipe is formed, gutter is fastened on water tank bottom, it is characterized in that bag is embedded with the annular flexible valve seat on the mouth of pipe of gutter, this valve seat is made with flexible rubber or plastic cement, its lip cross section becomes wedge-like, valve block and valve block lid are made for hard material, the sealing valve block of forming a hollow sealing formula hemispherical or taper, center of gravity regulating block or liquid are arranged in it, valve block is that sphere contacts or conical surface contact with valve seat, the ring-type gag lever post also is installed on the bleed off pipe, and the center line of this ring overlaps with stay cord.

Accompanying drawing is the flexible valve seat drain valve structure of a flush toilet schematic diagram.

The utility model embodiment is described further below in conjunction with accompanying drawing, accompanying drawing is the flexible valve seat drain valve structure of a flush toilet schematic diagram, this draining valve is made up of draining knob 1, lever 2, stay cord 3, valve block 4, gutter 5, bleed off pipe 6, the bottom of gutter 5 is fastened on the bottom of water tank 11, is the delivery port of flushing the toilet, and mouth of pipe place, gutter top bag is embedded with the flexible valve seat 7 of ring-type, this valve seat is made with flexible rubber, its lip cross section becomes wedge-like, and is last soft hard down, can closely contact with spherical valve block 4.Valve block 4 is made with valve block lid 8 usefulness rigid plastics or copper material, form a hemispherical sealing valve block that is difficult for the hollow sealing formula of deformation, its crucial part is that with the contact surface of valve seat be that sphere contacts, and to increase contact surface, the deformation lock ring that utilizes valve seat 7 wedge shape lips simultaneously is on spherical valve block 4.Spherical valve block 4 also can be made cone, obtains the better seal performance equally.The bottom of spherical valve block 4 is equipped with center of gravity adjuster 9, the center of gravity adjuster is a gravity block or an amount of liquid, its effect is to lower the center of gravity, keep the stable and adjustment valve block buoyancy of valve block, when draining, can produce bigger water hammer power simultaneously with current direction, automatic centering closed valve seat 7 and gutter 5, this water hammer power can also make the lip of flexible valve seat 7 that the sphere position that valve block 4 is closely wrapped up in bigger deformation takes place, water hammer power then relies on the deadweight of valve block and the water pressure of water tank to seal after disappearing, therefore, the gravity block of center of gravity adjuster 9 will be selected a suitable weight, and the static pressure that makes water is greater than the buoyancy of water to hollow valve block.

The middle part of bleed off pipe 6 also is fastened with gag lever post 10, and the gag lever post extending area is a ring-type, and its center line overlaps with stay cord 3.When turn draining knob 1, the lever of interlock 2 promotes valve blocks lid 8 by stay cord 3, make the valve block lid be inserted in the ring-type gag lever post 10 till, can prevent that so hollow valve block 4 drift in water tank is indefinite, the rapid centering sealing draining mouth of pipe when also being convenient to draining.

The utility model adopts flexible valve seat, change traditional flat seal contact into sphere or conical surface contact, on the one hand increase contact area, what make full use of hollow valve block on the other hand improves the sealing performance of draining valve from the static pressure of gravity, water hammer power and water, prevents radiator leak.The utility model is simple in structure, and is safe and reliable, good seal performance, and water saving obviously can be used in various flush toilet, also can use in other high level cisterns.
