Description
Technical field
The utility model relates to a kind of valve, and in particular, the utility model relates to a kind of low torque ball valve.
Background technique
At present, fixing ball valve is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, pressure release.Can be used for controlling various types of fluids such as air, water, steam, various Korrosionsmedium, mud, oil product; But the most switching torque of existing fixing ball valve is bigger than normal, thus makes valve rod, filler pressing sleeve, land equidimension is bigger than normal, increases the cost of overall valve, and the final controlling element type selecting simultaneously matched with valve also increases, thus increases cost and waste energy.
Model utility content
The purpose of this utility model is to solve existing above-mentioned problem, provides a kind of low torque ball valve.
For realizing above object, the technical solution of the utility model is a kind of low torque ball valve, comprise valve body, valve gap, it is characterized in that, described valve gap is provided with valve seat, described valve seat is flexibly connected with valve gap, described valve inner is provided with spool, described spool is flexibly connected with valve body, described spool is provided with rotatingshaft, described rotatingshaft is fixedly connected with spool, described spool both sides are provided with dunnage, described dunnage is fixedly connected with valve gap, described spool is provided with interior rolling ring, described interior rolling ring is fixedly connected with spool, described dunnage is provided with outer rolling ring, described outer rolling ring is fixedly connected with dunnage, ball is provided with between described interior rolling ring and outer rolling ring.By the outer rolling ring in rolling ring on spool and dunnage and the ball between interior rolling ring and outer rolling ring, decrease the friction between dunnage and spool, thus decrease the moment of torsion of ball valve core.
As preferably, be provided with seal ring between described spool and valve seat, described seal ring and spool are fitted, and described seal ring is fixedly connected with valve seat.Seal ring plays seal action, prevents liquid from valve seat gap leakage.
As preferably, be provided with spring between described valve gap and valve seat, described spring is flexibly connected with valve seat.Spring mainly solves the self-tightening sealing of valve pipe pressure when low pressure, provides initial pretightening force, thus ensures that pipeline pressure is lower than can effective sealing during 0.6Mpa.
As preferably, be provided with pin between described dunnage and valve gap, described pin is all fixedly connected with valve gap with dunnage.Pin is used for fixed support plate, and prevents dunnage from rocking in valve body.
As preferably, described valve body is provided with sewage draining exit, and described sewage draining exit is provided with drain plug, and described drain plug is fixedly connected with valve body.The convenient dirt getting rid of valve inner of sewage draining exit, drain plug is for blocking sewage draining exit.
As preferably, described valve body is connected with flange plate, described flange plate is fixedly connected with between valve body.Flange plate is used for connection of rotating handle or automatical control system.
As preferably, be provided with supporting foot below described valve body, described supporting foot is fixedly connected with valve body.Supporting foot, for supporting valve, facilitates the installation of valve and miscellaneous part.
The utility model has following beneficial effect: easy to use, reduces valve global switch moment of torsion, thus reduces valve rod, Gland, land equidimension, to reduce valve cost; Reduce valve actuator, thus energy saving and reducing costs.
