Description
Technical field
The present invention relates to valve technology fields, and the automatic mechanical valve for making up abrasion is automatically closed more particularly, to a kind of
Core.
Background technique
Existing cutting off the water and class valve is automatically closed is divided into 2 major class on the market: it is simple but at high cost one is DYN dynamic structure,
Remaining to be divided into metal conic face or planar shaped and rubber plug, metal cone-shaped face belongs to recessed positive or plane cooperation
Hard sealing, the high error of the big required precision of difficulty is big in actual processing, and sealed working face is easy to wear in use, burn into stops
Impurity causes to leak when closing, the sealing of rubber plug the disadvantage is that easy to aging, abrasion pipeline medium clean degree is required it is high,
But in actual use often due to give up light material, scum, the iron in face are cut in the raw material band residual PE or PPR welding that pipeline maintenance generates
Other reasons such as rust, the grains of sand cause the not tight water dripping of rubber stopper bayonet, separately due to themselves the friction such as above two big types
Resistance is big and causes the heavy rotating cycle of valve switch more, and it is due light and handy flexible and convenient to lose valve switch, and frictional resistance
The switch service life of bigger valve will reduce at double, and the ceramic valve plate of another existing valve with ceramic spool sealing in the market is to lean on
Fit clearance come when sealing, therefore reaching mild wear oneself be not closed completely and be not durable.

Further, the top of the valve rod 9 is provided with convolution spring 18, and the spring 18 that circles round does not have pressure in valve core inside
When, reset valve rod 9.
The working principle of the present apparatus: water from water inlet 16 flow into, be full of valve core inside, pressure will push valve rod shaft 10,
Upwards, downwards, the recessed sky of the two of moving valve plate 11 crosses two sectors in water portion 112 and fixed valve plate 12 to moving valve plate 11 to rotating ring piece 7 at this time
Hole 121 is staggered completely, and entire spool is in closed state, is rotated by 90 ° when turning valve rod 9, because the lower surface of valve rod shaft 10
The rectangular recess 111 of rectangular cam 1002 and moving valve plate 11 cooperates, and moving valve plate 11 is also rotated by 90 °, at this time the two of fixed valve plate 12
Scallop hole 121 leaks out, and water flow is flowed out by scallop hole 121, and spool is open state at this time, and valve rod is rotated by 90 ° upon closing, is made
The recessed empty water portion 112 of crossing of moving valve plate 11 is staggered scallop hole 121, reaches sealing effect, because of the effect of hydraulic pressure, moving valve plate 11 and fixed
Valve block 12, rotating ring piece 7 and determine ring plate 6 and suffers from relatively large frictional force, and the rotating force for the spring 18 that circles round does not work, when stopping
When water, hydraulic pressure disappears, moving valve plate 11 and fixed valve plate 12, and rotating ring piece 7 is opposite with frictional force between ring plate 6 determine to become smaller, time
Rotation spring 18 can control the rotation of valve rod 9 to moving valve plate 11 and 12 closed position of fixed valve plate, no matter moving valve plate 11 and fixed valve plate 12 and
Rotating ring piece 7 and determine ring plate 6 how fretting wear, when closed hydraulic pressure can all make moving valve plate 11 and 12 rotating ring piece 7 of fixed valve plate with calmly
Ring plate 6 is close together, thus will not leak due to abrasion.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention may be used also on the basis of the above description for those of ordinary skill in the art
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is all to belong to this hair
The obvious changes or variations that bright technical solution is extended out are still in the scope of protection of the present invention.
