Description
Technical field
The utility model belongs to valve technology field, particularly relates to a kind of eccentric spherical floating valve door.
Background technique
Valve is widely used in industrial field, usually the flow control in various fluid or gas medium transport process is applied to, ball valve is the one in numerous valve, it normally carrys out the keying of control valve by spiral with holes, but traditional ball valve usually causes biting because of the mismatch error of spherical crown and valve seat in the process used, the problem such as jam or scuffing, not only reduces the working life of valve, also there is potential safety hazard.
Model utility content
in order to solve existing the problems referred to above, the utility model provides a kind of eccentric spherical floating valve door, and its structure simple operations is convenient, even if spherical crown can be made still to play the effect of effective sealing in case of wearing by eccentric rotary.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of eccentric spherical floating valve door, comprise valve body, valve seat and main shaft, the inside of described valve body is provided with spheroid, spheroid upper outer wall is also provided with spherical crown, main shaft is connected with spheroid through valve body, collar bush is provided with in the outside of main shaft, collar bush and valve body shaping, also countershaft is provided with outside the spheroid on main shaft opposite, one end of countershaft is fixedly connected with spheroid, the other end passes valve body, valve body outside countershaft is provided with countershaft cover, countershaft cover is shaping with valve body, flange is equipped with at the two ends of valve body, the flange of one end directly and valve body be connected and fixed, the flange of the other end is fixedly connected with valve seat by trim ring, valve seat is fixedly connected with valve body, also valve gap is provided with in the port, outer end of valve seat, the center line of main shaft and countershaft overlaps, this center line does not overlap with any diameter of spheroid.
Preferably, the outer end port of collar bush is also provided with compressing tablet, and compressing tablet is enclosed within main shaft.
Preferably, the outside, one end passing valve body at countershaft is provided with end cap.
Preferably, support leg is also provided with at the lower outside of valve body.
Preferably, described end cap adopts copper.
Preferably, described spherical crown adopts Austenitic Stainless Steel.
The beneficial effect that the utility model reaches is: its structure simple operations is convenient, can be compensated the wearing and tearing of valve sealing face, and the fluid resistance produced is little by the elastic floating that valve seat is radial and axial.
