Description

Three-way valve

The present invention relates to a valve member, and more particularly to a three-way valve that is relatively reliable, smooth, and relatively less obstructive to fluid flow and flow rate.

According to the general pipeline for transporting liquid or gas (such as water pipes, oil pipes, various compressed gas pipelines or gas pipelines), it must be composed of multiple pipelines except for the limitation of the length of the pipeline. In addition to the articulation, fluids can also be transferred to different components (or equipment) by means of piping arrangements; and, in general, the valve members are used to form the conduits so that they are further controlled by the valve members. The tubing is blocked or turned on to control the supply of fluid or to control the direction of fluid transport.

Among them, the three-way valve is generally used in the fluid pipeline as one of the valve members for controlling the supply of fluid; in principle, the three-way valve is provided with three open ends on the valve body thereof, and A valve hole is formed in the passage of one of the open ends, and a valve plug for shielding the valve hole is disposed at the valve hole, and the valve body is provided with a relative extension into the valve body and coupled with the valve plug for The driving element that drives the valve plug is caused to be driven by the driving element to change the state in which the valve hole is shielded or the valve hole is opened.

Generally, the valve plug of the conventional three-way valve is a normal spherical or circular plate that shields the valve hole, mainly through the way of rotating in place, so that the perforation on the ball is facing the valve hole or the plate of the circular plate is The valve holes are staggered so that the fluid can pass through the sphere The perforation or the gap between the circular plate and the valve hole passes through, so as to open the valve hole.

However, similar to the conventional three-way valve, the valve hole must be completely shielded under the dimensional accuracy of the valve plug body and the valve hole completely, which not only requires high processing cost, but also increases the valve plug movement. The friction resistance; and, in the state in which the valve plug completely opens the valve hole, the valve plug itself is still disposed in the valve hole, thereby hindering the flow rate and flow rate of the fluid, and is less suitable for the fluid of a large diameter. Used in pipelines.

The directional displacement of the first valve bore 121 causes the first valve bore 121 to open, thereby creating a handling effect of transferring fluid from the conduits on both sides into the bottom conduit, or stopping the recirculation or retraction of fluid fluid.

It is worth mentioning that there is no frictional resistance between the valve plug 30 of the three-way valve of the present invention and the first valve hole 121, and the valve plug 30 can react quickly under the driving of the power cylinder 20, so A relatively reliable and smooth operation effect is obtained, and the valve plug 30 is completely in a state in which the output shaft 21 of the power cylinder 20 drives the valve plug 30 to move away from the first valve hole 121 to open the first valve hole 121. Exiting the first valve hole 121 does not hinder the flow rate and flow rate of the fluid, and is particularly suitable for use in a large-diameter fluid line. Of course, the three-way valve of this creation can also be applied to a small-diameter fluid line.

Furthermore, as shown in the third and fourth figures, the two open ends 11 of the valve body 10 are respectively disposed on two corresponding sides of the valve body 10, and another open end 11 is disposed on the valve.
