Embodiment 1

[0033] Such as Figure 1-6 As shown, an integrated jacketed ball valve includes a valve body 6, an end cover 8 and a valve ball 14 are installed in the valve body 6, a sealing pressure ring 9 and a support ring 11 are installed in the valve body 6, and the support ring 11 is The valve seat 16 is installed, the seal 10 is installed between the support ring 11 and the sealing pressure ring 9; the valve body 6 has a snap-in groove 61, and the outer surface of the end cover 8 is integrally formed with an outer ring 812, which can be snapped The end cover 8 is evenly opened with a plurality of fastening holes 811 , and fastening pieces that can be in contact with the sealing pressure ring 9 are installed in the fastening holes 811 .

[0034] Preferably, the fastener is a hexagon socket head cap screw 7, the seal 10 is a gasket, an O-ring 13 and a braided graphite 12 are installed between the valve seat 16 and the support ring 11, and a plurality of spring holes 112 are opened in th...

Embodiment 2

[0037] Such as Figure 1-5 As shown, on the basis of the above-mentioned embodiment 1, this embodiment provides a preferred structure that can make the end cover 8 easier to install: the end cover 8 includes a plurality of end face blocks 81 that are independent of each other, and each end face block 81 Both have fastening holes 811 , and an outer ring 812 is integrally formed on the outer surface of each end block 81 .

[0038]In this embodiment: the dividing line is on the fastening hole 811, which can effectively prevent the end cover 8 from sliding and falling off towards the middle cavity of the valve body 6, and can stabilize the position of the end cover 8, because the end cover 8 includes a plurality of independent end face blocks 81 , so the gap between the dividing lines of the end cover 8 can be made relatively large, and the outer rings 812 of the divided end face blocks 81 are snapped into the snap-fit ​​grooves 61 from the inside to the outside respectively, whil...

Embodiment 3

[0041] Such as figure 1 As shown, on the basis of the above-mentioned embodiment 1, this embodiment provides a preferred structure that can further make the sealing performance of the entire ball valve better: one end of the valve ball 14 is installed with a lower end that passes through the valve body 6 Valve stem 1, there is a channel 101 communicating with the valve body 6 in the lower valve stem 1, a screw plug 2 is installed in the channel 101, the valve body 6 and the lower valve stem 1 are connected by a stud 4, and the stud 4 is installed with A winding pad 3 is installed between the nut 5, the valve body 6 and the lower valve stem 1 . By installing the winding gasket 3 between the valve body 6 and the lower valve stem 1, the sealing performance between the valve body 6 and the lower valve stem 1 can be improved.

[0042] Preferably, the other end of the valve ball 14 is equipped with an upper valve stem 19 passing through the valve body 6, and a stuffing box 21 is in...

Abstract

The invention relates to the technical field of ball valves, in particular to an integrated jacket ball valve. The integrated jacket ball valve is used for solving the problems that in the prior art, an integrated jacket type ball valve is poor in end cover sealing effect and large in end cover assembling difficulty. The integrated jacket ball valve comprises a valve body, an end cover and a valve ball are installed in the valve body, a sealing pressing ring and a supporting ring are further installed in the valve body, a valve seat is installed in the supporting ring, and a sealing piece is installed between the supporting ring and the sealing pressing ring; and a clamping groove is formed in the valve body, an outer ring is integrally formed on the outer surface of the end cover, the outer ring can be clamped into the clamping groove, a plurality of fastening holes are evenly formed in the end cover, and fasteners capable of making contact with the sealing pressing ring are installed in the fastening holes. The end cover is clamped in the clamping groove through the outer ring, so that the end cover can be installed, and the end cover is easier to install; and the pressing degree of the sealing piece can be adjusted by adjusting the fastening piece, so that the sealing effect of the end cover is better.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to an integrated jacketed ball valve. Background technique [0002] Jacketed ball valves are widely used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport high-viscosity media that will solidify or crystallize at room temperature. Jacketed ball valves are welded metal clips on the basis of ball valves. The sleeve is used to inject steam or other heat preservation and cold preservation medium to ensure the normal operation of the medium in the valve. Jacketed ball valve is also called heat preservation ball valve. Jacketed ball valve has good heat preservation and cold preservation characteristics. The diameter of the valve is consistent with the diameter of the pipe. At the same time, it can effectively reduce the heat loss of the medium in the pipeline. When the ordinary ball valve transports high-viscosity medium that will solidify or crys...
