[0003] In view of the problems existing in the prior art, the present utility model provides a ball valve with a novel NW interface to solve at least one of the above technical problems.

[0004] The technical solution of the utility model is: a ball valve with a novel NW interface, comprising a ball valve body, characterized in that the ball valve body comprises a valve body, the upper end of the valve body is connected to a valve stem, an O-ring is provided at the connection between the valve stem and the valve body, and the O-ring is sleeved on the valve stem, the outside of the valve body is connected to a handle, the valve stem is located inside the handle, and the handle is locked on the valve stem by a nut, a ball is further provided in the valve body, and sealing gaskets are provided at both ends of the ball;

[0005] The lower end of the valve body is connected to the lower NW interface, and the right end of the valve body is connected to the right NW interface. The right NW interface and the sealing gasket are fastened to the valve body through the valve cap. A sealing ring is provided inside the right NW interface. The lower NW interface and the right NW interface are both connected to the inside of the sphere.

[0006] This new model reduces the use of converters, saves costs and reduces the failure rate; it also offers more optional accessories for engineering project design. The exclusive connection structure provides a more prominent sealing effect, filling a product gap.

[0007] Further preferably, the outer diameters of the right NW interface and the lower NW interface gradually decrease from close to the valve body to far away from the valve body, and the installation position of the valve cap is close to the valve body.

[0008] Thereby achieving a better sealing effect.

[0009] Further preferably, there are two O-rings, and the stem of the valve stem is provided with two annular grooves. o The sealing rings are respectively sleeved in the two annular grooves.

[0010] The sealing effect can be better achieved through two O-rings.

[0011] Further preferably, the outer wall of the valve body is provided with a limiting protrusion, and the outer wall of the handle is provided with a notch, and the notch abuts against the limiting protrusion.

[0012] This can limit the rotation range of the handle to prevent it from being too large and affecting its use.

[0013] Further preferably, the sealing ring inside the right NW interface is close to the valve body.

[0014] Thereby achieving a better sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Reference Figure 1-Figure 2 As shown, a ball valve with a novel NW interface includes a ball valve body, characterized in that the ball valve body includes a valve body 4, the upper end of the valve body is connected to a valve stem 3, an O-ring is provided at the connection between the valve stem and the valve body, and the O-ring is sleeved on the valve stem, the outside of the valve body is connected to a handle 2, the valve stem is located inside the handle, and the handle is locked on the valve stem by a nut 1, a sphere 6 is also provided in the valve body, and sealing gaskets 5 are provided at both ends of the sphere; the lower end of the valve body is connected to the lower NW interface 41, and the right end of the valve body is connected to the right NW interface 71, the right NW interface and the sealing gasket are fastened to the valve body through a valve cap 7, a sealing ring is provided inside the right NW interface, and the lower NW interface and the right NW interface are both connected to the inside of the sphere.

[0020] This new model reduces the use of converters, saves costs and reduces the failure rate; it also offers more optional accessories for engineering project design. The exclusive connection structure provides a more prominent sealing effect, filling a product gap.

[0021] Further preferably, the outer diameters of the right NW interface and the lower NW interface gradually decrease from close to the valve body to away from the valve body, and the installation position of the valve cap is close to the valve body, so as to achieve a better sealing effect.

[0022] Further preferably, two O-rings are provided, and the stem of the valve stem is provided with two annular grooves, and the O-rings are respectively sleeved in the two annular grooves. The two O-rings can achieve a better sealing effect.

[0023] Further preferably, the outer wall of the valve body is provided with a limiting protrusion, and the outer wall of the handle is provided with a notch, and the notch abuts against the limiting protrusion, thereby limiting the rotation range of the handle and preventing excessive rotation from affecting use.

[0024] Further preferably, the sealing ring inside the right NW interface is close to the valve body, so as to achieve a better sealing effect.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
