Abstract
The utility model relates to a dry type pressure resistant ceramic valve core. A fluid inlet hole and a liquid outlet hole are arranged on a lower ceramic sheet, and a hollow cavity is arranged in an upper ceramic sheet. When a valve is opened, the hollow cavity, the liquid inlet hole and the liquid outlet hole form a liquid channel. With the dry type pressure resistant ceramic valve core adopted, when the utility model is used, other parts of a valve body keep dry, so a sealing ring between the valve body and the valve can be omitted. Thus, the favorable pressure resistant ability is provided. The dry type pressure resistant ceramic valve core can be made into a screwed type valve core or a stud type valve core according to different valves. The utility model has the advantages of simple structure, convenient installation and operation, long service life, good sealing performance, and favorable pressure resistant performance.
Description
The utility model relates to a kind of of many uses, withstand voltage properties ceramic valve core preferably, belongs to plumbing and valve technology field, specifically refers to the withstand voltage ceramic valve core of a kind of dry type.
Existing valve spool generally all adopts rubber parts as air locking, also there is the stainless steel of employing to cooperate as Sealing with rubber parts, this type valve core all exists the disadvantage that sealing effect is relatively poor and working life is short, the patent No. is that 93221788 " a kind of low noise energy-saving water tap ceramic valve core " solved above-mentioned deficiency preferably, but exist following deficiency: this spool is when work, current pass down ceramic plate and last ceramic plate enters in the valve body, flow out by valve body then, whole spool all is immersed in the water, impose motive sealing by the O RunddichtringO between valve rod and the valve core, thereby its voltage endurance capability is relatively poor, general withstand voltage all below 0.6MPa when opening state, be difficult to satisfy the higher application of requirement of withstand voltage.
The utility model purpose just is to provide a kind of dry type withstand voltage ceramic valve core, to pass through its unique fluid channel structure, it is the cavity that fluid passage that fluid passes down ceramic plate enters ceramic plate, again by another fluid passage outflow of ceramic plate down, other parts of valve body keep dry, and reduced seal ring between valve body and the valve, thereby make it have voltage endurance capability preferably, the various advantages that both kept prior art have preferably overcome simultaneously the deficiencies in the prior art again effectively.
The purpose of this utility model realizes in the following manner: the withstand voltage ceramic valve core of a kind of dry type, mainly form by valve body, valve rod, packing ring, cushion, ceramic valve plate and seal washer, it is characterized in that above-mentioned ceramic valve plate is made up of last ceramic plate and following ceramic plate, on following ceramic plate, have the fluid hand-hole and fluid portals, last ceramic plate with contacted of following ceramic plate on have the cavity that fluid hand-hole and fluid portal on the ceramic plate under can being communicated with, when valve opening, above-mentioned cavity portals with fluid hand-hole and fluid and forms the fluid passage.
Adopt the withstand voltage ceramic valve core of dry type of the present utility model, owing to adopted the fluid channel structure of unique uniqueness, it is the cavity that fluid passage that fluid passes down ceramic plate enters ceramic plate, again by another fluid passage outflow of ceramic plate down, other parts of valve body are kept dry, and thereby the seal ring that has reduced between valve body and the valve makes it have voltage endurance capability preferably, and this spool can be made the spool of screw-in or hitching post formula according to different valves, and utilized the premium properties of the sealing and the adjusting of ceramic valve plate fully, thereby the advantage that has both kept prior art preferably, the deficiencies in the prior art have been overcome simultaneously again effectively, have simple and reasonable, easy to install, long service life, the advantage of good seal performance and good pressure-resistant performance is the withstand voltage ceramic valve core of a kind of comparatively desirable dry type.
Description of drawings.
Fig. 1 is a kind of screw-in example structure schematic representation of the present utility model;
