Embodiment Construction

[0013] like figure 1 and figure 2 As shown, the valve body 6 has three ports in different directions, the three ports are the upper port 1, the left port 2 and the right port 3 respectively, and the three ports communicate with the valve cavity respectively, the valve cavity is a spherical body, and the spherical cavity in the valve cavity slides A spherical spool 5 is mated and connected, and the spherical spool 5 has a bidirectional flow guide 4 and an axial drive shaft 7, the drive shaft 7 and the bidirectional flow guide 4 form 90 degrees, and the rotation of the drive shaft 7 can make the bidirectional flow guide 4 The openings at both ends are separated and communicated with the upper port 1 and the left port 2 or the upper port 1 and the right port 3, and the three ports can also be isolated from each other. The two-way guide channel 4 forms a 90-degree angle between the two openings, and the two openings are transitioned by a curve.

Abstract

The invention belongs to a stop valve, and in particular relates to a two-way flow-guiding stop valve, which is characterized in that a valve body (6) is provided with three openings in different directions; the three openings are an upper opening (1), a left opening (2) and a right opening (3), and are communicated with a valve cavity respectively; the valve cavity is a spherical surface body; the inner surface of the valve cavity is in slide fit and connection with a spherical valve core (5); the spherical valve core (5) is provided with a two-way flow-guiding passage (4) and an axial driving shaft (7); the driving shaft (7) is at an angle of 90 degrees to the two-way flow-guiding passage (4); and the rotation of the driving shaft (7) can enable openings at two ends of the two-way flow-guiding passage (4) to be communicated with the upper opening (1) and the left opening (2) or with the upper opening (1) and the right opening (3), and can isolate the three openings from each other. The stop valve not only solves troublesome manual operation, but also can reduce the cost for purchasing valves in engineering by more than a half.

Description

technical field [0001] The invention belongs to a cut-off valve, in particular to a two-way guide flow cut-off valve. Background technique [0002] At present, in many fluid transportation projects, there are various needs for switching processes and distributing fluids, especially in the process of oil and gas collection and transportation, which occur more frequently. For example: in the pig sending and recovery process, a bypass system must be used to reverse the process back and forth to allow the pig to enter or exit the pipeline. [0003] In addition, the fluid is transported downstream and supplied to many users respectively, and there will be many diversion control points. Each control point generally requires three valves to control the direction and flow of the fluid. [0004] In pipeline transportation projects, the cost of control valves accounts for a considerable proportion of the entire project cost, and the more control valves there are, the more difficult i...
