Abstract
The utility model provides a titanium material ball valve sealed firmly, includes valve body, disk seat, spheroid and the valve rod of titanium system, and the outer wall department of valve rod is provided with the filler, and disk seat and spheroidal surface all are provided with hard coating film, and both hard sealed cooperations, and disk seat movable mounting still with being loaded with belleville spring on the disk seat, constitutes sealed wearing and tearing elasticity compensation mechanism in the valve body. The utility model discloses a rational in infrastructure, the hard coating film on disk seat and spheroid surface can improve hardness and corrosion resistance greatly, and both cooperate the switch nimble, difficult wearing and tearing to the sealed vice sufficient pretightning force that has can be guaranteed to butterfly type spring, even a small amount of wearing and tearing of sealed face appear, the valve can continue to guarantee to have good sealing performance under elasticity compensation, and the reliability is high.
Description
The hard seal ball valve that technical field: the utility model relates to a kind of ball valve, particularly titanium material make.
Background technique: ball valve is valve conventional in process pipelines, the corrosive medium of some pipeline conveying is strong, and the pellet hardness contained is high, and temperature is high, and pressure is large, and the corresponding ball valve also needing employing special substance, as titanium material hard seal ball valve.Although general titanium material spheroid and valve seat hardness fair, under the corrosion of special media is washed away, hardness or not ideal enough, easy sealing surface wear, and under high temperature and high pressure condition, tiny sealing wear also there will be leakage contribution and produces.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, seals reliable titanium material hard seal ball valve.
The utility model comprises the valve body of titanium, valve seat, spheroid and valve rod, the outer wall place of valve rod is provided with filler, the surface of valve seat and spheroid is provided with cured film, and both are sealed and matched firmly, valve seat is movably arranged in valve body, valve seat is also loaded with belleville spring, forms sealing wear elastic compensating mechanism.
Of the present utility model rational in infrastructure, the cured film of valve seat and spherome surface can improve hardness and corrosion resistance greatly, both coordinate switch flexible, not easy to wear, and butterfly spring can ensure that sealing pair has enough pretightening forces, even if occur that sealing surface weares and teares on a small quantity, can continue to ensure good seal performance at elastic compensating effect lower valve, reliability is high.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Embodiment: as shown in the figure, valve body 1, valve seat 2, spheroid 3 and valve rod 4 are all titanium system, the outer wall place of valve rod 4 is provided with filler 5, the surface of valve seat 2 and spheroid 3 is provided with cured film, and both are sealed and matched firmly, valve seat 2 is movably arranged in valve body 1, and valve seat 2 is also loaded with belleville spring 6, forms sealing wear elastic compensating mechanism.
The seal ring 7 of the present embodiment between valve seat 2 and valve body 1 adopts Expanded graphite material, filler 5 also adopts Expanded graphite material, utilize the resistance to high temperature of Expanded graphite like this, not only also can guarantee reliable sealing in case of fire, and under worst hot case component thermal expansion can absorb by Expanded graphite, can ensure that valve at high temperature can not be risen extremely, and can at high temperature open and close flexibly.
