Abstract
The utility model relates to a wear-resistant leakage-proof ceramic valve core which is a main part for manufacturing novel water taps, water cut-off doors and various straight-way type cut-off valves and belongs to a hardware water heating device. The utility model is formed by that a ceramic moving sheet 4 and a ceramic fixed sheet 5 are superimposed together from top to bottom and is characterized in that a shifting groove 9 and a flashing bowl groove 10 are arranged on the ceramic moving sheet 4; an inlet and outlet hole 11 and a positioning pin hole 12 are arranged on the ceramic fixed sheet 5; the diameter of the moving sheet is smaller than that of the fixed sheet 5; the smooth surfaces are superimposed. The utility model with the advantages of simple structure, wear resistance, corrosion prevention and leakage prevention overcomes the defects of old type structures, increases the sealing strength, extends the service life, and achieves the effect of energy conservation.
Description
The utility model is a kind of wear-resisting leakproof ceramic valve core, is the critical piece of making new type water tap water pipe valve and various straight-through stop valve doors, belongs to the five metals plumbing.
At present, no matter be that employed water tap, water pipe valve and various straight-through stop valve door all have century-old history in life or the every field of producing.This old-fashioned structure mostly screws skin money (or metal plug) by screw rod and oil sealing seals, and pressure is unidirectional, these in addition the parts long period of soaking in high pressure water-bath or other solution, and easily cause the screw thread on the screw rod to get rusty, corrode, oil sealing, skin money or the wearing and tearing of metal plug.A new valve often uses less than some months and phenomenons such as run, drip, leak will occur.Cause the waste of great amount of water resources and other energy.Also caused the waste of a large amount of fund for the replacing of these valves or maintenance simultaneously.
The purpose of this utility model provides a kind of novel wear-resisting, anticorrosion, leakproof ceramic valve core, to overcome old-fashioned structural deficiency, increases sealing intensity and working life.
The purpose of this utility model is achieved in that wear-resisting leakproof ceramic valve core is overlapped together up and down by ceramic moving plate 4 and ceramic stator 5 and forms.(seeing accompanying drawing 1,2) is characterized in that ceramic moving plate 4 is provided with allocating slot 9, reverse water bowl groove 10; Ceramic stator 5 is provided with manhole appendix 11, positioning pin hole 12; And the diameter of moving plate is less than the diameter of stator, and the light face laminates; The bottom surface of stator (accompanying drawing 6) is provided with sealing ring small embossment and positioning pin hole 12; When forming valve body, seal ring 7 is pressed on ceramic stator 5 times by positioning pin hole 12 is spacing, on the valve seat 8, does not allow water or other solution drain to part beyond ceramic moving plate 4 and the ceramic stator 5, in order to avoid corrode other metal position.Rotate ceramic moving plate 4 as long as pass through allocating slot 9 during work, but with regard to the opening and closing valve.When reverse water bowl groove 10 overlapped with manhole appendix 11, valve was opening state, just formed path; During the half-twist dislocation, valve is closed condition, just forms closed circuit;
The utility model is simple in structure, wear-resisting, anticorrosion, leakproof, has overcome old-fashioned structural deficiency, has increased sealing intensity and working life, has played the effect of energy saving.
The utility model is described in further detail below in conjunction with drawings and Examples:

Wherein: 1, valve rod 2, blind nut 3, swivel nut 4, ceramic moving plate 5, ceramic stator 6, valve pocket 7, seal ring 8, valve seat 9, allocating slot 10, reverse water bowl groove 11, manhole appendix 12, positioning pin hole 13, fastening screw.
From accompanying drawing 10,11 as can be known present embodiment mainly by valve rod 1, blind nut 2, swivel nut 3, ceramic moving plate 4, ceramic stator 5, valve pocket 6, seal ring 7, valve seat 8, positioning pin hole 12, be arranged in order and form from top to bottom.Pottery moving plate 4 and ceramic stator 5 overlap together up and down forms wear-resisting leakproof ceramic valve core.It is characterized in that ceramic moving plate 4 is provided with allocating slot 9, reverse water bowl groove 10; Ceramic stator 5 is provided with manhole appendix 11, positioning pin hole 12; And the diameter of moving plate is less than the diameter of stator, and the light face laminates; The bottom surface of stator is provided with sealing ring small embossment and positioning pin hole 12; Seal ring 7 is pressed on ceramic stator 5 times by positioning pin hole 12 is spacing, on the valve seat 8, does not allow water or other solution drain to part beyond ceramic moving plate 4 and the ceramic stator 5, in order to avoid corrode other metal position.During work, rotate ceramic moving plate 4 by valve rod 1 drive and by allocating slot 9, when reverse water bowl groove 10 overlapped with manhole appendix 11, valve was opening state, just formed path; Valve rod 1 drives and during by the dislocation of allocating slot 9 half-twists, valve is closed condition, just forms closed circuit; Valve seat 8 will be connected with water supply pipe or other solution conveyor tube road.The angle controllable flow amount of regulating valve stem or the size of other liquid inventory.
Reverse water bowl groove 10, manhole appendix 11 are designed to fan-shaped here, are characterized in that little, the molten amount of valve volume is big, flow resistance is little.The sectional area of sectorial area and groove can be determined according to the flow rate calculation of various valves.Wear-resisting leakproof ceramic valve core is made according to ceramic process and required precision with corundum matter or corundum mullite rock structural ceramic material (GB5593-85).(bending strength 〉=2400Kg/CM) and hardness (the hard 7-9 of Mohs) are assemblied in the valve the inside to have quite high mechanical strength.Water or other solution can only pass through in the spool the inside.Therefore other position does not contact with water or other solution does not have corrosive action, is difficult for getting rusty, even if there is wear phenomenon to be only limited between ceramic moving plate 4 and the ceramic stator 5, therefore can accomplish that the wear-resisting leakproof life-span is long yet.
