Abstract
The utility model relates to an oxygen ball valve which comprises a left valve body, a right valve body, a valve rod and a ball. A supporting stand is fixedly arranged on the right valve body, fitting of stuffing is provided between the tight valve and the valve rod, the upper portion of the valve rod that rotationally connected with the supporting stand is transmitting connected with a hand wheel, the lower portion of the valve rod is transmitting connected with the ball, valve seats and sealing plates are provided in both left and right valve bodies, and the supporting stand forms a sealing structure which makes the valve rod separated from the extraneous. The beneficial effect of the utility model is that because a cover board is provided with the supporting stand that forms a sealing structure which makes the valve rod separated from the extraneous, dusts and greasy dirt will not get into the valve rod and the valve body, thereby has the advantages of cleanness (dust-proof, grease-proof), long service life and good fail-safe reliability. The upper portion of the valve rod is transmitting connected with the hand wheel via a worm wheel and a worm, which makes the turn-on and the turn-off of the valve easy, and the static-proof bolts makes the valve safer.
Description
Technical field:
The utility model relates to a kind of valve, relates in particular to a kind of oxygen ball valve.
Background technique:
As everyone knows, the oxygen ball valve is a kind of valve commonly used, generally comprise left valve barrel, valve rod, spheroid, right valve barrel etc., on valve body, be installed with support, be provided with stuffing box packing between valve body and the valve rod, the upper end and the handwheel of the valve rod that is rotationally connected with support are in transmission connection, and the lower end and the spheroid of valve rod are in transmission connection, and are provided with the sealing surface that constitutes valve seat in left valve barrel and the right valve barrel.The oxygen ball valve is mainly made cut-out, throttling, branch adapted on pipeline.The support of the special-purpose oxygen ball valve of the oxygen of prior art is a hatch frame, and dust and greasy dirt enter in valve rod and the valve body easily, and valve is polluted, not only influence the normal use of valve, shorten the working life of valve, also reduced the purity and the quality of oxygen, have potential safety hazard.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good oxygen ball valve of cleaning, long service life, Security is provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the oxygen ball valve, comprise left valve barrel, right valve barrel, valve rod and spheroid, on right valve barrel, be installed with support, be provided with stuffing box packing between right valve barrel and the valve rod, the upper end and the handwheel of the valve rod that is rotationally connected with support are in transmission connection, the lower end and the spheroid of valve rod are in transmission connection, and are provided with the sealing surface that constitutes valve seat in left valve barrel and the right valve barrel, prop up to be configured to a sealing configuration that the valve rod and the external world are separated.
Useful technique effect of the present utility model is: because support is provided with cover plate, constitute one and make valve rod and the extraneous sealing configuration that separates, dust and greasy dirt can not enter in valve rod and the valve body, thereby have cleaning clean (dustproof, grease proofing), long service life, advantage that Security is good; The upper end of valve rod is in transmission connection by worm gear and worm screw and handwheel, makes valve opening and closes flexibly easily; The antistatic bolt makes valve safer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
