Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] like figure 1 and figure 2 The new regulating ball valve shown includes: packing plate 1, packing gland 2, packing 3, braided layer 3.1, elastic layer 3.2, upper valve stem 4, valve stem bearing 5, lower valve stem 6, valve core 7, valve seat 8. The pressure ring 9 and the valve core bearing 10, the valve core 7 and the valve seat 8 are installed in the valve body, the valve seat 8 is fixedly installed in the valve body through the pressure ring 9, and the lower end of the upper valve stem 4 passes through the top of the valve body. The through hole is fixedly installed on the top of the valve core 7, and the upper end of the upper valve stem 4 passes through the through hole at the bottom of the valve body and is fixedly installed on the bottom of the valve core 7. A valve stem bearing is arranged between the upper valve stem 4 and the valve body. 5. The t...

Abstract

The invention discloses a new type of regulating ball valve, which comprises a packing pressure plate, a packing gland, a packing, an upper valve stem, a valve stem bearing, a lower valve stem, a valve core and a valve seat. The valve core and the valve seat are installed in the valve body. The valve seat is fixedly installed in the valve body through the pressure ring, the lower end of the upper valve stem is fixedly installed on the top of the valve core through the through hole at the top of the valve body, and the upper end of the upper valve stem is fixedly installed on the valve core through the through hole at the bottom of the valve body There is a stem bearing between the upper valve stem and the valve body, and a packing is provided on the top of the valve stem bearing, and the packing is pressed between the upper valve stem and the valve body through the packing gland and the packing pressure plate. In the cavity; the filler is packing, and the filler includes a braided layer and an elastic layer, and the braided layer is arranged outside the elastic layer and wraps the elastic layer. The technical purpose of the present invention is to provide a new type of regulating ball valve with more reliable valve stem seal and more durable valve stem seal.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel regulating ball valve. Background technique [0002] The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly, and the cut-off ball valve is a kind of cut-off valve. [0003] The existing regulating ball valve stem and valve core often leak, the seal at the valve stem is unreliable, and the packing at the valve stem is prone to aging after a long period of use, and the packing tends to lack elasticity, making the valve stem The reliability of the seal is reduced. Contents of the invention [0004] In view of the shortcomings of the above regulating ball valve, the technical purpose of the present invention is to provide a new type of regulating ball valve with more reliable valve stem seal and more durable valve stem seal. [0005] The presen...
