Description
Technical field
The utility model relates to the toilet by eccentric screens rotating valve control.
Background technology
The valve of rotary type as ball valve, barrel valve, cone valve, is common valve version with the spool closed channel, because the mutual applying of contact surface during rotation, need overcome very big frictional force, just can make it to produce mutual angle displacement in housing.This makes that not only valve is easy to damage, and the keying of valve is also quite required great effort, and if can reduce even eliminate the suffered friction of sealing surfaces when rotating, and makes it to adapt to various actual needs (for example being applied on the toilet), will have great practical value.
The utility model content
The purpose of this utility model provides a kind of toilet by eccentric screens rotating valve control.
The purpose of this utility model is achieved in that
The utility model comprises closestool body, water inlet, sewage draining exit and blowdown channel thereof, it is characterized in that, is provided with the eccentric screens rotating valve of control water seal and blowdown at place, described blowdown channel.
Described eccentric screens rotating valve comprises housing and spool, it is characterized in that: spool places the cam of valve block inwall to form by valve block and movable top.
Described housing is the ducted body that its inwall radian and valve block are complementary, and it radially is provided with opening, and axial centre bore can turn the location therebetween for the rotating shaft of cam, is provided with stopping means at the inwall of housing.
Described valve block is made up of arc surface that is complementary with inner walls and the side plate that has loose slot, and side plate is positioned at the two ends of arc surface, is provided with cylinder or ball at the inwall of described arc surface.Flexible member (spring leaf or spring steel wire) is installed on the side plate of valve block.
Described cam is made up of eccentric wheel and rotating shaft, and detent is positioned at the nearer or nearest place, near-end position of distance between eccentric wheel periphery and rotating shaft, and its detent and cylinder or ball are complementary.
The rotating shaft of described cam is placed in the loose slot of valve block, is combined into spool mutually with valve block, and flexible member produces cam and valve block each other and draws close.
The spool that assembles is installed in the housing, and rotating shaft is placed in the centre bore that is complementary with it on the housing.
Because the utility model has adopted technique scheme, thereby can cancel the water bending design of existing toilet, place the cam of valve block inwall to form spool by valve block and movable top, rotation by cam produces axially and displacement radially valve block, in the rotation of valve block before arriving sealing station with the separated attitude of inner walls, when separation place that arrives sealing station, push it against sealing station by the rotation of cam.Because spool is when rotating, valve block does not contact with inner walls, so be easy to make it rotate, when eccentric wheel valve block when inner walls promotes, because valve block and inner walls are in the process of a progressive overhead, displacement is more or less freely, only needs less power can make valve block fit with inner walls or separate, thereby makes valve closing or unlatching.Not only reduced frictional force significantly, and, also can guarantee sealing effectiveness.

The specific embodiment
Embodiment 1
Below in conjunction with drawings and the embodiments in detail the utility model is described in detail.
As shown in the figure:
The utility model comprises closestool body, water inlet, sewage draining exit and blowdown channel thereof, it is characterized in that, is provided with the eccentric screens rotating valve of control water seal and blowdown at place, described blowdown channel.
Described eccentric screens rotating valve comprises housing 1 and spool 2, it is characterized in that: spool 2 places the cam 4 of valve block inwall to form by valve block 3 and movable top.
Described housing 1 is the ducted body that its inwall radian and valve block are complementary, and it radially is provided with opening 5, and axial centre bore 6 can turn the location therebetween for the rotating shaft 14 of cam 4, is provided with several stopping means (being illustrated as 7A, 7B) at the inwall of housing.
Described valve block 3 is made up of arc surface 8 that is complementary with inner walls and the side plate 10 that has loose slot 9, side plate 10 is positioned at the two ends of arc surface, inwall at described arc surface is provided with cylinder or ball 11, and flexible member 12 (spring leaf or spring wire or spring) is installed on the side plate 10 of valve block.
Described cam 4 is made up of eccentric wheel 13 and rotating shaft 14, and detent 15 is positioned at the nearest place, near-end position of distance between eccentric wheel periphery and rotating shaft, and its detent and cylinder or ball are complementary.
The rotating shaft of described cam is placed in the loose slot of valve block, is combined into spool 2 mutually with valve block, and flexible member produces cam and valve block each other and draws close.
The spool 2 that assembles is installed in the housing 1, and rotating shaft 14 is placed in the centre bore 6 that is complementary with it on the housing.
Described valve flank bottom closestool body is installed in blowdown channel or the sewage draining exit place in the toilet.
Described valve is installed in blowdown channel or sewage draining exit place in the toilet by the closestool body bottom rear.
Below be the valve event explanation that has assembled:
As shown in Figure 1: when place outside the eccentric wheel 13 and rotating shaft between distance far-end 17 far away when being positioned at cylinder 11 places of valve block inwall, arc surface 8 fits with inner walls, an opening 5 on the valve block closure casing, valve is in closed condition.Counterclockwise rotate the cam of forming by eccentric wheel 13 and rotating shaft 14 4 in the present embodiment, slide on eccentric cylinder that is trapped among the valve block inwall outward or the ball.Because valve block and inner walls fit, friction is bigger, does not rotate so valve block is not followed eccentric wheel.
As shown in Figure 2: under eccentric wheel that is rotating and flexible member (being illustrated as spring leaf) interaction, valve block begins to separate with inner walls, when cylinder on detent on turning to eccentric wheel and the valve block inwall or ball are in same position, under the effect of flexible member, detent and cylinder or ball interlock (see figure 3), this moment, valve block and inner walls got loose, be rotated further eccentric wheel, eccentric wheel drives the valve block that has got loose with inner walls and rotates, meeting stopping means 7A (being illustrated as limited block) up to valve block stops operating, this moment, valve block left the opening on the housing, and valve is in opening (Fig. 4).
When valve-off, toward the counter-rotation eccentric wheel, because cylinder or ball and detent still are in interlocking pattern (Fig. 4), eccentric wheel drives valve block and runs into stopping means 7B place (Fig. 3) toward counter-rotation until valve block together, valve block is kept off can not rotate, eccentric wheel then is rotated further, because the torsion that rotates has surpassed the pressure of detent to cylinder or ball, detent on the eccentric wheel skids off (Fig. 2) from cylinder or ball, under the eccentric wheel effect of rotating, valve block is pushed to inner walls, and valve block and inner walls are fitted mutually, opening on the housing is sealed by valve block, and this moment, valve was in closed condition (Fig. 1).
Spool of the present utility model is when rotating, because valve block does not contact with inner walls, so be easy to make it rotate, when eccentric wheel valve block when inner walls promotes, because valve block and inner walls are in the process of a progressive overhead, displacement is more or less freely, only needs less power that valve block and inner walls are fitted, thereby makes valve closing.
