Abstract
The utility model relates to a C-shaped eccentric semi-spherical valve, which includes a valve body, a valve rod and an eccentric semi-spherical body, wherein one end of the valve rod is arranged in the valve body in a penetrating manner and is fixedly connected with the eccentric semi-spherical body, a drive device is arranged at the other end, and a valve seat matched with the eccentric semi-spherical body is arranged in the valve body. The C-shaped eccentric semi-spherical valve is characterized in that the eccentric semi-spherical body has a C-shaped axial section. The technical scheme provided by the utility model has the effect of improving the seal performance of the semi-spherical body and the valve seat.
Description
Technical field
The utility model relates to a kind of eccentric half-ball valve, is specifically related to a kind of C type eccentric half-ball valve.
Background technique
Traditional eccentric half-ball valve, generally include valve body, valve rod and eccentric semi-spherical body, valve rod one end is arranged in the valve body fixedlys connected with the eccentric semi-spherical body, the valve rod the other end is provided with its drive unit, be provided with the valve seat that matches with the eccentric semi-spherical body in the valve body, yet the fitting surface of its eccentric semi-spherical body and valve seat is the setting of " V " font, and its eccentric semi-spherical body and valve base sealing effect are not quite desirable.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide the C type eccentric half-ball valve of a kind of eccentric semi-spherical body and valve base sealing better effects if.
For achieving the above object, the utility model provides following technological scheme: a kind of C type eccentric half-ball valve, comprise valve body, valve rod and eccentric semi-spherical body, valve rod one end is arranged in the valve body fixedlys connected with the eccentric semi-spherical body, the valve rod the other end is provided with its drive unit, be provided with the valve seat that matches with the eccentric semi-spherical body in the valve body, it is characterized in that: described eccentric semi-spherical axon is the setting of " C " font to tangent plane.
By adopting technique scheme, the eccentric semi-spherical axon is the setting of " C " font to tangent plane, makes eccentric semi-spherical body and valve base sealing better effects if; And, be hidden in the valve pocket because open the eccentric hemisphere in back, no flow resistance direct current channel, runner is unimpeded dust stratification or stuck phenomenon can not to occur, and the pressure loss is little, and medium can not be deposited in the valve pocket; Because eccentric principle, eccentric semi-spherical body and valve seat are separated from fully during unlatching, do not have any contact, and open and close torque is little, and turning 90 degrees is able to turn on or off finishing, and operates light; This valve is when cutting out under the effect of two off-centre, and eccentric semi-spherical body and valve seat close tighter and tighter, reaches good sealing purpose fully; Have between the eccentric semi-spherical body of hemisphere otch and the valve seat and shear and squeeze and cut effect, can effectively remove the fouling or the dirt of sealing surface, keep good sealing.When this valve under the effect of two off-centre is being opened; eccentric semi-spherical body and valve seat are separated from fully; there is not any contact; eccentric semi-spherical body and valve seat can not produce friction; the ball seal face of conventional ball valve and the problem that sealing surface of seat rubs have all the time very effectively been overcome, so sealing surface is subjected to excellent protection.
The utility model further is set to: described eccentric semi-spherical body one end is provided with cross section vertically and is the axis hole that polygonal is provided with, the corresponding eccentric semi-spherical body of described valve rod one end cross section is with the polygonal of the suitable setting of axis hole and is plugged in the axis hole, and described eccentric semi-spherical body is fixedlyed connected by link with valve rod.
By adopting technique scheme, changed the axis hole of traditional big semicircle column construction and the valve rod that matches with axis hole, make that the valve rod driving torque is bigger.
The utility model also further is set to: described axis hole cross section is the regular hexagon setting, and the corresponding eccentric semi-spherical body of described valve rod one end cross section is the regular hexagon with the suitable setting of axis hole.
By adopting technique scheme, make that further the valve rod driving torque is bigger.
Below in conjunction with accompanying drawing the utility model is further described.
