Abstract

The utility model discloses a biswitch ceramic valve assembly and a biswitch valve core equipped with the same. The biswitch ceramic valve assembly comprises a fixed sheet and a movable sheet, wherein four through holes are formed on the fixed sheet, namely a cold water inlet, a cold water outlet, a hot water inlet and a hot water outlet; the two adjacent through holes on the fixed sheet are formed inside an inner annular belt and an outer annular belt respectively to form one group; the other two through holes on the fixed sheet are also formed inside an inner annular belt and an outer annular belt respectively to form one group; the two groups of through holes are radially symmetrical; two radially symmetrical concave cavities are formed on the movable sheet; each concave cavity on the movable sheet can cover the two through holes which are communicated on the fixed sheet and correspond to the concave cavity; and when the movable sheet rotates on the fixed sheet along the axis of the fixed sheet, each concave cavity on the movable sheet can communicate or close two through holes which are formed on the fixed sheet correspond to the concave cavity at the same time, so as to open and close in a biswitch way and throttle cold water and hot water. The biswitch ceramic valve can be combined with a shell, a base, an upper sealing ring, a lower sealing ring, a poking plate and a poking rod into a cold water and hot water biswitch valve core. The valve core is applied to a thermostatic valve and other cold water and hot water mixing valves, is anti-freezing in winter, and can also be applied to other split mixing valves.

Description

A kind of biswitch ceramic valve plate assembly and the biswitch spool of this assembly is housed

Technical field

The utility model relates to a kind of biswitch ceramic valve plate assembly and the biswitch spool of this assembly is housed, and is suitable for thermostatic valve etc. and needs using in the water mixing valve of biswitch and binodal stream.

Background technique

The switch of present thermostatic valve mostly is located at the waterexit end of mixing water; Because valve water when closing is many, so winter is easy freezing, one of designer's patent ZL97234037.8; Adopted the biswitch throttling valve core; Though have the biswitch and double fluid amount regulating action of hot and cold water,, limited application because it is a composite structure.

The model utility content

The biswitch spool that the utility model provides a kind of biswitch ceramic valve plate assembly on the basis of the above and this assembly is housed makes it to be applied to be difficult for freezing valve in the thermostatic valve, but also can make various split type valves.

The utility model improves the ceramic valve plate assembly in the above-mentioned patent, and said a kind of biswitch ceramic valve plate assembly comprises a stator and a moving plate, and moving plate can rotate in its axle center in the stator upper edge; Stator is provided with four through holes, and they are respectively hot water or cold water's inlet/outlet, and moving plate is provided with two cavitys; On the stator inside and outside two wherein adjacent through hole offices of four through holes in the two-layer ring belt; Become one group, and in addition two through holes become another group also inside and outside the office in the two-layer ring belt; Two through holes in one group are symmetry with the diameter with two through holes of another group respectively; Two cavitys on the moving plate are symmetry with the diameter, and each cavity on the moving plate can cover and be communicated with corresponding with it and two adjacent through holes on the stator, when the axle center of moving plate stator in the stator upper edge turns to certain position; Each cavity on the moving plate can be communicated with corresponding with it on the stator and two adjacent through holes simultaneously or turn-offs, with the biswitch and the throttling of realization hot and cold water.

A kind of biswitch spool; Comprise housing, chassis, go up parts commonly used in seal ring, lower seal, dial and these prior arts of driving lever and be arranged at dial and last seal ring between biswitch throttle valve plate assembly together; Can form the biswitch spool, biswitch throttle valve plate assembly wherein adopts above-mentioned moving plate and stator.

Because this spool can make through the independent respectively outflow of the hot and cold water of throttling; With itself and constant temperature valve core fit applications in thermostatic valve because its switching position is in cold and hot inlet end, thus with the switch of general thermostatic valve to be arranged on the waterexit end of mixing water different; Can save the safety check of former water inlet; Water easy-storing not in the valve closing rear valve body like this, winter is antifreeze, cooperates with other mixed valve cores in addition also to can be applicable in other various split type mixing valves.

Embodiment

Biswitch ceramic valve plate assembly embodiment

Fig. 1-4 has explained structure, matching relationship and the different relative position of stator and moving plate among the biswitch ceramic valve plate assembly embodiment in the utility model; Wherein the dotted line among Fig. 4 is represented the cavity E of moving plate 2, the profile line of F, the relative position relation the when a among Fig. 4, b, c figure have represented that moving plate and stator are in closed condition, semi-open and full open respectively.

Said biswitch ceramic valve plate assembly comprises a stator 1 and a moving plate 2, and moving plate 2 can rotate in its axle center in stator 1 upper edge; Stator 1 is provided with four through hole A, B, C, D; They are respectively hot water or cold water's inlet/outlet, inside and outside two wherein adjacent through hole A of four through hole A, B, C, D, the C office in the two-layer ring belt, become one group on the stator 1; And in addition two through hole B, D also inside and outside the office in the two-layer ring belt; Become another group, two through holes of one group A and C are symmetrical with the B of another group with the diameter with two through holes of D respectively, and having on the moving plate 2 with the diameter is symmetrical two cavity E, F; Each cavity on the moving plate 2 can cover and be communicated with corresponding with it and two adjacent through holes on the stator 1; When moving plate 2 rotated counterclockwise certain position in the axle center of stator 1 upper edge stator 1, each cavity on the moving plate 2 can be communicated with corresponding with it on the stator 1 and two adjacent through holes simultaneously or turn-offs, with the biswitch and the throttling of realization hot and cold water.
