Description
Technical field
The utility model relates to a kind of shut-off valve, especially a kind of ceramic flat surface sealed stop valve.
Background technique
Existing shut-off valve, such as entitled three-way switching ceramic stop valve CN200920179544.3, use flap
Ceramic seal, entitled switching mode ceramic stop valve CN201320675545.3, also uses flap ceramic seal, and add
Sealing ring or entitled adjustable elastic ceramic stop valve CN201610975171.5, use spring to seal, but this
The sealing effect of sample is undesirable, and especially structure is complicated, is not easy to repair, affects service life.Above-mentioned patent shut-off valve
Sealing structure be lifting structure, for the fluid containing granule foreign, be easy to happen impurity when valve is closed and be stuck in sealing pair
Above fit badly.
In the prior art, entitled wheel-type full-enclosed permanent-magnet valve CN00130740.1 is used outside valve body as magnet ring group
At totally-enclosed valve body, wheel disc mentions in upper valve body, is linked to be entirety with following valve rod, wheel disk body is circumferentially uniformly distributed two
Above iron block, for outer magnetic ring loop in the outside of upper valve body, the inside is axially uniformly distributed two pieces or more of permanent magnet, and with
Iron block in wheel disk body attracts relationship correspondingly, to control opening and closing valve.Further, to water flowing face in embodiment
In the case that product is small, ceramic tap is such as disclosed, is made of in valve chamber ceramic stator and ceramic movable plate, valve rod and wheel disk body
Spool.Inserted with ceramic movable plate on valve rod, and flat seal relationship is formed with ceramic stator.But disadvantage is that valve body
The water inlet and water outlet of two sides not point-blank, and by the constraint of set dynamic, stator shape, circulation
It is smaller, and flow resistance is larger, thus be only suitable for water flowing area it is small in the case where.
The prior art is improved in conclusion having, proposes a kind of demand of novel cutoff valve.
Summary of the invention
The purpose of this utility model is to propose a kind of shut-off valve, is a kind of ceramic flat surface sealing electric-control stop valve, the cut-off
Point-blank, valve body center line and the straight line are in an angle, the angle non-90 to the inlet and outlet of valve body two sides
Degree；Valve body inner spool is from bottom to top by fixed valve plate, moving valve plate, shift fork and driving device；The fixed valve plate is one with semicircle
The plane ceramic valve block of through-hole, the moving valve plate are a plane ceramic valve block with semicircle blind hole；Through-hole on fixed valve plate
It is corresponded with the blind hole shape on moving valve plate；The aperture position of through-hole on the fixed valve plate is directed towards valve inleting water mouth one
Side, to reduce flow resistance.
Further, the sealing surface of the moving valve plate is the through-hole for covering fixed valve plate, and equal for the ease of control circulation
Even variation, the sealing surface have biggish covering surplus compared with through hole section.
Further, fixed valve plate is fastened in valve body by symmetrically arranged boss；
Further, moving valve plate is fixedly connected with the shift fork for connecting driving device by symmetrically arranged groove, works as rotation
When driving device, moving valve plate can be controlled by shift fork, complete the work opened or closed.
The utility model ceramic flat surface sealing electric-control stop valve has the characteristics that resistance to impurity, wear-resisting, corrosion resistant, passes through valve body
The characteristics of center line and two sides water inlet and water outlet constitute y-type structure in an angle, realizes low flow resistance.

Specific embodiment
It is a kind of ceramic flat surface sealing electric-control stop valve of the utility model, 3 two sides of stop valve body such as Fig. 1 to Fig. 7
Water inlet 20 and water outlet 21 point-blank, valve body center line and the straight line are in an angle, the angle non-90 degree；Valve body
Inner spool is from bottom to top by fixed valve plate 1, moving valve plate 2, shift fork 4 and driving device 5；The fixed valve plate is one with semi-circular through hole
Plane ceramic valve block, the moving valve plate is a plane ceramic valve block with semicircle blind hole；Through-hole 31 on fixed valve plate with
32 shape of blind hole on moving valve plate corresponds；The aperture position of through-hole on the fixed valve plate is directed towards valve inleting water mouth one
Side, to reduce flow resistance.
Further, the sealing surface of the moving valve plate is the through-hole for covering fixed valve plate, and equal for the ease of control circulation
Even variation, the sealing surface have biggish covering surplus compared with through hole section.
Further, fixed valve plate is fastened in valve body by symmetrically arranged boss；
Further, moving valve plate is fixedly connected with the shift fork for connecting driving device by symmetrically arranged groove, works as rotation
When driving device, moving valve plate can be controlled by shift fork, as shown in figure 8, being the shift fork with reinforcing rib, complete to open
Or the work closed.
The utility model ceramic flat surface sealing electric-control stop valve has the characteristics that resistance to impurity, wear-resisting, corrosion resistant, passes through valve body
The characteristics of center line and two sides inlet and outlet constitute y-type structure in an angle, realizes low flow resistance.
