Abstract
The utility model relates to the technical field of a valve, and in particular to a novel ceramic corrosion-resistant spherical valve, which is characterized by comprising a valve rod 1, packing 2, a spherical body 3, a valve seat 4 and a valve body 5. All structures of the spherical body, the valve body and the like which are contacted with the medium are made of Rockwell hardness HRC90 ceramic material. The spherical body 3 is manufactured in a grinding way and is sealed with the valve seat 4. The metal part of the spherical body and the valve body which is contacted with the ceramic completely adopts the thermal matching process. The combination is firm and reliable, and the abrasion resistance and corrosion resistance are good.
Description
Technical field
The utility model relates to the fluid engineering valve field, especially a kind of new ceramics corrosion resistant ball valve.
Background technique
Ball valve is to be developed by stopcock.It has identical revolving and turn 90 degrees and propose action, and different is that faucet body is a spheroid, manhole or passage is arranged by its axis.The ratio of sphere and passway should be such, promptly revolves when turning 90 degrees when ball, should all present sphere at the inlet/outlet place, thereby block mobile.But spheroid bears the load and the corrosion of working medium, under the situation of especially big at pressure and severe corrosive, can cause valve invalidation, thereby limit the suitable narrow limitation of ball valve.
Summary of the invention
The utility model purpose originally is in order to overcome the ball valve narrow limitation; Provide that a kind of application area is wider, the longer service life ball valve.Of the present utility model being characterised in that comprises valve rod 1 filler 2 spheroids 3 valve seats 4 valve bodies 5.Be structural ceramic material in all parts that contact with medium, its chemical stability and extreme hardness (Rockwell hardness HRC90) are only second to diamond.Spheroid 3 adopts advanced grinding equipment and technology manufacturing, ball circularity precision height, and surface quality is good, after grinding with 4 pairs of valve seats, utilizes the self lubricity of Zr02 pottery, desirable good sealability.Be titanium alloy valve and Monel valve 2-4 doubly.
Metal and ceramic contact segment all adopt hot allotment of labor's skill, in conjunction with solid and reliable, have strengthened ceramic mechanical strength, allow structural ceramics really become ceramic steel.
Adopt complete symmetric design, double seal is not only arranged, and do not flow to restriction, can two-wayly use, the life-span can double virtually.
The good wear resistance of pottery makes the utility model durable in use, and reliability is high, long service life, be titanium alloy valve and Monel valve 2-4 doubly.
Being used for the granule medium of high hardness, or soft particle is arranged but having in the medium of corrosion, the utlity model has unrivaled absolute predominance, also is the valve of unique suitable this type of medium at present.
The beneficial effects of the utility model are: 1) the utility model can be used for the granule medium of high hardness, soft particle is arranged but has in the medium of corrosion, has improved product working life and has broken through the use narrow limitation of conventional ball valve; 2) working life of prolongation product; 3) having reduced the difficulty of producing helps producing in batches.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
Metal and ceramic contact segment all adopt hot allotment of labor's skill, in conjunction with solid and reliable, have strengthened ceramic mechanical strength, allow structural ceramics really become ceramic steel.
Adopt complete symmetric design, double seal is not only arranged, and do not flow to restriction, can two-wayly use, the life-span can double virtually.
