Abstract

The utility model discloses a flush toilet sewer valve which is fully sealed and can save water. The flush toilet sewer valve adopts a valve ball and a valve body to replace the turning plate of a turning plate type sewer valve with the prior art. The valve ball is synchronously connected with a flushing water valve through the applying force handle of a valve stem. When a toilet needs to be flushed, the water valve and the ball valve can be simultaneously opened through the actions of a connecting rod and the applying force handle. The toilet can be flushed with water saving, and odor can be separated. After the toilet is flushed, the water valve and the ball valve can be simultaneously closed through the action of the applying force handle.

Description

Flush toilet sewer valve

The utility model relates to water valve under a kind of toilet, especially connect the following water valve that biomass pool and so on needs the higher toilet of tightness.

Water valve under the existing toilet, the turnover plate type valves that adopt more, the effect that is the little weight by a hanging is fitted turnover panel and sewer pipe mouth, reach sealing, when flushing water is after an action of the bowels put into toilet and is reached a certain amount of, the power on the turnover panel of acting on is during greater than the active force of the little weight of hanging, turnover panel unlatching flushing water is taken and is just entered sewer pipe, reach the effect of flushing, but water valve is with a little weight effect under this turnover plate type, it is not very tight that turnover panel and sewer pipe are fitted, leak easily, long meeting service time one make the slit between turnover panel and the sewer pipe bigger in mouth of pipe fouling, and the foul smell in ight soil pond is escaped from sewer pipe, and each leaching requirement increases, the toilet that connects biomass pool especially for the rural area because blow-by and washing water quantity are big, influences the efficient of biomass pool fermentation.

The purpose of this utility model provides water valve under a kind of novel toilet, and it can make good sealing between toilet and the sewer pipe, reaches when washing after an action of the bowels water saving and isolates the effect of escaping on the foul smell.

The purpose of this utility model is that following mode realizes: in the interface that following water adapter is sewer pipe and toilet two valve bodies and a ball valve that has valve rod up and down are set, valve body is the circular arc surfaces of revolution of making interference fits with valve ball towards the face of valve ball up and down, and valve ball is opened a cylindrical hole vertical with the valve rod central axis direction.Valve ball is in its cylindrical hole position vertical with sewer pipe when unused state, makes the sphere driving fit of valve body and valve ball, reaches sealing effectiveness; When user mode, make valve ball go to its cylindrical hole over against sewer pipe mouth and toilet delivery port, just water enters sewer pipe smoothly by the cylindrical hole of valve ball.

Water valve under the toilet provided by the utility model owing to adopted a ball valve to be installed in the drainage pipeline of toilet, can tightly be isolated aqueous vapor, can reach the effect that water saving flushing and anti-foul smell escape.

Technical characterictic of the present utility model is also remarked additionally by following embodiment and accompanying drawing thereof.

Fig. 1 is the axial section schematic diagram of the utility model in user mode.

Among the figure: water is taken over the 2--valve ball under the 1--

3--upper valve body 4--packing ring

5--toilet 6--application of force handle

Valve body under the 7--valve rod 8--

With reference to Fig. 1, two valve bodies that the annular low pressure polyethylene injection moulding of sufficient intensity arranged are separately positioned on two positions up and down of taking over (1) as the following water of housing and are valve body (3,8) up and down, two valve bodies respectively have a circular arc surfaces of revolution, wherein descend valve body to take over following water and are made into integration.The valve ball (2) of same material is embedded in the arc surfaces of revolution of two valve bodies.The arc rotation and the sphere of valve body are enough smooth, both can closely be pasted mutually, and can relatively rotate.Upper valve body (3) center has that there is a hole at valve body (8) center under the slick and sly horn mouth that big mouth makes progress, and there is a cylinder limbers at the valve ball center.The loudspeaker end opening of upper valve body and the limbers of valve ball and down the cylindrical hole of valve body can form a unimpeded limbers after be connected and be connected with sewer pipe.Valve ball (2) is gone up the vertical valve rod (7) of being cast by duroplasts that is connected with center cylindrical hole and is stretched out the external of housing, the outer end of valve rod connects application of force handle (6), application of force handle is that the application of force handle of water supply valve is connected with connecting rod with the running water pipe valve of the flushing that discharges water, and makes their synchronous working.

The following horn mouth diameter d of upper valve body and the limbers diameter d of valve ball reach the cylindrical hole diameter d of valve body down, can satisfy following relation: d≤d≤d.

During unused state, the running water pipe valve closing by connecting rod effect valve ball (2), is in the hole plumbness of its limbers and valve body simultaneously, and the front and back sphere of valve ball has been sealed the outlet pass of valve body up and down respectively, makes down water valve be in closed condition.In the time need washing after an action of the bowels, open the valve of running water pipe, make hole that valve ball rotates to limbers and valve body over against being connected by connecting rod effect application of force handle, the water band just that thing enters sewer pipe by the limbers, reaches the effect of flushing.Toilet (5) down under the mouth of a river and the toilet upper valve body horn mouth of water valve be connected by a packing ring (4).

Claims

1, the utility model is a water valve under a kind of toilet, it is characterized in that during water is taken under toilet a ball valve being installed, ball valve is taken over valve body up and down in the cavity, is embedded in two valve balls between valve body by being installed in down water, be fixed on valve ball up and down water and take over vertical valve rod formation, wherein valve body is the arc surfaces of revolution of making interference fits with valve ball towards the face of valve ball up and down.

2, water valve under the toilet as claimed in claim 1, the slick and sly horn mouth that it is characterized in that having in the upper valve body big mouth to make progress, bell-mouthed lower port diameter is identical with limbers diameter in the valve ball.

3, water valve under the toilet as claimed in claim 1 or 2 is characterized in that valve body is connected as a single entity with following water adapter down.

4, water valve under the toilet as claimed in claim 1 is characterized in that being equipped with on the valve rod between the point of application of application of force handle and its point of application and toilet water supply valve application of force handle and is connected with a connecting rod.
