Abstract

The invention relates to a valve. Valves are widely used in a fluid control system and can make a fluid system stably and effectively execute related functions. One core can be used for independently controlling circulation of the fluid in the two directions, the dual-purpose effect of the core is achieved, and therefore the system structure can be compact and simplified. According to the principle, pore channels perpendicular to each other and not communicated are formed in a similar spherical structure and wind around a pair of specific quadrature axes passing through the sphere center respectively, and therefore the circulation area of each flow channel is controlled independently.

Description

A kind of valve that independently can control the flowing of both direction fluid

Technical field

The invention belongs to liquid control system, there is the effect that a spool can control two fluid flows simultaneously independently, there is the effect optimizing fluid structure systems.

Background technique

Fluid system is in order to perform concrete function, wherein the flowing of fluid needs by just right control, a large amount of valves is used to the flowing controlling fluid in fluid system accurately, the present invention is that utilization one has through hole and the valve of rotary spheroid, by rotating, independently controls the circulation of two intersecting channels, the usage quantity of fluid system valve can be reduced, compact structure, the effect of simplified system structure and mitigation system weight, plays the effect of optimization system.

Summary of the invention

Independently can control a valve for both direction fluid flowing, it is characterized in that, spool entirety is ball shape structure, constructs orthogonal channel thereon, and described spool can respectively around parallel with orthogonal channel and rotated by the orthogonal running shaft of the centre of sphere; Described valve also comprises transverse fluid channels and longitudinal flow passage, spool is placed between transverse fluid channels and longitudinal flow passage, the crosswise joint effort formation of valve, longitudinally control effort formation embed spool, the circulation area of crosspassage is changed independently, by controlling longitudinally to control the circulation area that effort formation changes vertical passage independently by controlling crosswise joint effort formation.

Embodiment

A kind of valve mechanism (with reference to Fig. 1-4), has orthogonal transverse fluid channels 8,12 and longitudinal flow passage 9,13 above; Be placed in by spherical spool 11 between transverse fluid channels 8,12 and longitudinal flow passage 9,13, passage inner circle covers spool 11 channel projection on its direction, and orthogonal running shaft 1,5 is by the centre of sphere of spool; The crosswise joint effort formation 7 of valve, longitudinally control effort formation 10 embed spool 11, both running shafts are respectively by orthogonal running shaft 1 and 5, the circulation area of crosspassage is changed independently, by controlling longitudinally to control the circulation area that effort formation 10 changes vertical passage independently by controlling crosswise joint effort formation 7.

During spool work, spool is placed in the middle of passage 8,12,9,13 pipeline, ensure spool 11 and passage 8,12,9 and 13 close contact, when needs change horizontal circulation area, crosswise joint effort formation 7 rotates around axle 1, and effort formation 10 rotates around axle 5 the longitudinal flow area that can rename.

Claims

1. one kind independently can control the valve of both direction fluid flowing, it is characterized in that: spool (11) entirety is ball shape structure, construct orthogonal channel (3,4) thereon, described spool can respectively around parallel with orthogonal channel (3,4) and rotated by the orthogonal running shaft (1,5) of the centre of sphere; Described valve also comprises transverse fluid channels (8,12) and longitudinal flow passage (9,13), spool (11) is placed between transverse fluid channels (8,12) and longitudinal flow passage (9,13), crosswise joint effort formation (7), longitudinal effort formation (10) that controls of valve embed spool (11), the circulation area of crosspassage is changed independently, by controlling longitudinally to control the circulation area that effort formation (10) changes vertical passage independently by controlling crosswise joint effort formation (7).
