Owing to flow, the temperature of water is to move or rotate and regulate in the fixing position of video disc 1 by this activity video disc 2, thus this two video disc superimposed surperficial 11,21 between be required the contact of driving fit completely, just can avoid the seepage of water; So the superimposed contact surface 11,21 because of general video disc is generally a no small area, and for making the complete driving fit of this superimposed surface of contact, so this contact surface 11,21 must have good true Pingdu and surperficial luminosity; Normally form because of these video discs again with the stupalith sintering, in the hope of higher hardness and abrasion performance characteristic, yet, because the physical property of the cold shrinkage and thermal expansion of material, Chang Wufa makes whole video disc have plat surface completely behind high temperature sintering, and also is to be difficult to avoid at the flaw (as pore or hole, concavo-convex hole) of sintered surface.Moreover, be superimposed the contact with whole surface between video disc 1 and the movable video disc 2 fixedly, under normal condition, the all very smooth smooth and fully driving fit of this superimposed surface of contact 11,21, therefore this surface of contact is subjected to the atmospheric pressure effect and produces huge retardance strength when both are superimposed, make activity video disc 2 become and be difficult to move or rotate, and cause controlling inflexible shortcoming.
For overcoming above-mentioned two shortcomings, the most mat of usual means adds a kind of thick lubricant grease as a means of overcoming between this superposed surfaces, utilize flaws such as the flatness of this lubricant grease revisal contact surface and pit, pore, reach the desired security seal effect of superimposed contact surface, and its lubricated usefulness of mat makes and is easy between video disc move or rotates, and promotes the flexibility of controlling.
Though the above-mentioned means that apply lubricant grease between two disc surface can solve aforesaid shortcoming, so on practice, but there is following problem to produce and treats further to overcome: the relative displacement when operating because of two video discs, this overlapping surface of contact must be contacted with the water liquid of flowing through, cause the lubricant grease that is coated with between the overlapping face, be everlasting and use after a period of time, grease will be taken off mistake by water erosion gradually, the effect of forfeiture lubricant medium, and because of containing the smooth surface that various impurity also can corrode valve block in the water, and cause the slip between surface of contact to have some setbacks and resistance on the contrary at surface accumulation incrustation scale.
In view of this, the utility model is improved at these shortcomings.
The novel main purpose of this reality is that the improved water supply control valve pottery of a kind of structure video disc will be provided, accumulate lubricant grease for holding, make superimposed surface of contact under the characteristics of possessing contact smoothness and applying precision, again can be in these little shrinkage pools constantly the supplemental lubrication grease to superimposed surface of contact, with keep this superimposed surface of contact move or rotary manipulation smoothly smooth and easy.
The purpose of this utility model is achieved in that
A kind of water supply control valve pottery video disc of architecture advances, mainly, it is characterized in that by a fixing video disc and movable video disc is superimposed forms: this fixedly video disc one of should the activity video disc or both surface portion of superimposed surface of contact be provided with a plurality of confessions and hold the little shrinkage pool that accumulates lubricant grease.
This kind is provided with some little shrinkage pools that are interspersed on the superimposed surface of contact of two ceramic video discs of water supply control valve, accumulate lubricant grease for holding, and De Changbao video disc smooth operation is smooth and easy.
Of the present utility model simple in structure, the lubricant grease in the shrinkage pool is supplemented between the superimposed surface of contact of video disc smoothly smooth and easy with normal maintenance operation, and tool economic and practical by the capillarity between two video disc surface of contact.
Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
Description of drawings:
