Abstract
The utility model provides a two-way reversing ball valve, comprising a valve body, a valve core, a valve cap, a valve seating ring, a regulating ring, a spring, a bearing and sealing members. The valve body is uniformly provided with four openings, and each opening is provided with a sealing member; the valve core has a ball structure, and the middle of the valve core is provided with two flowing passages, and the sealing surface of valve body is a spherical surface. The sealing of the utility model adopts the dual fail-safe structure of the spherical surface and the sealing members. The utility model which can be widely used in oilfield piston type oil-measuring apparatuses has long service life and low cost.
Description
One, technical field
The utility model relates to valve, particularly a kind of bilateral commutation ball valve.
Two, background technique
The commutation parts of existing commutation ball valve are installed hollow " 0 " shape seal ring for making the platy structure of " Z " shape along outer rim, make its expansion and seal by oil hydraulic pump, commutate after the pressure release.The selector valve of this structure exists shortcoming or deficiencies such as complex structure, installation and processing difficulty, cost height, inconvenient operation.
Three, summary of the invention
The technical problems to be solved in the utility model provides a kind of improved bilateral commutation ball valve, and it can overcome shortcoming or the deficiency that exists in the above-mentioned prior art effectively.
Bilateral commutation ball valve described in the utility model comprises valve body, spool, valve gap, seat ring, adjustment circle, spring, bearing and Sealing, and described valve body is provided with four uniform valve ports, and each passage port is installed on Sealing.Described spool is a spheroidal structure, is provided with two flow channels of isolating mutually in the middle of it, and the sealing surface of spool and valve body is a sphere.
Wherein, the sealed member of described spool and valve body also is installed on Sealing, and the sealing part is placed in the seat ring.
Wherein, described seat ring is installed in valve passage mouth and seal spool place, installs spring thereafter and adjusts circle.
The utility model has following advantage compared with prior art:
1, simple in structure, easy operating can manually-operable, also can electric operating
2, sphere and Sealing dual fail-safe structure are adopted in sealing, and be safe and reliable, long service life, and cost is low.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cross-sectional schematic shown in Figure 1.
Five, embodiment
Referring to Fig. 1-Fig. 2, a kind of bilateral commutation ball valve comprises valve body 5, spool 8, valve gap 7, seat ring 6, adjusts circle 2, spring 4, bearing 9 and Sealing 3.Valve body 5 is provided with four uniform valve ports 51,52,53,54, and each passage port is installed Sealing 3.Spool 8 is a spherical structure, is installed in the valve body 5, is provided with two flow channels 81 and 82 of isolating mutually in the middle of the spool 8, sealing surface 10 ball face sealings of spool 8 and valve body 5.Spool 8 also is installed on Sealing 3 with valve body 5 sealing positions, and sealing part 3 is installed in the seat ring 6, and seat ring 6 is installed in valve port 51,52,53,54 and seal spool place, installs spring 4 thereafter and adjusts circle 2.Install seal ring 1 on the surface of contact of seat ring and valve port.
