Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0021] Such as figure 1 As shown, the balanced three-way cut-off regulating valve includes a valve body 1 and a valve core 3. The valve body 1 is provided with a first flow channel 11, a second flow channel 12 and a third flow channel 13 inside. The first flow channel 11 is relatively parallel to the second flow channel 12, the third flow channel 13 is vertical to the first flow channel 11, the third flow channel 13 is coaxial with the valve core 3, and the first flow channel 11 is connected ...

The invention discloses a balanced three-way shut-off regulating valve which comprises a valve body and a valve core, wherein a first flow channel, a second flow channel and a third flow channel are arranged inside the valve body; an upper valve seat is mounted between the first flow channel and the second flow channel; a three-way sleeve is arranged at the flow channel opening of the third flow channel; a lower valve seat is mounted above the three-way sleeve; the valve core is composed of a valve core body, a valve core cover, a partition plate and a balance pipe which are integrally arranged; the lower part of the valve core penetrates through the lower valve sear; the middle of the valve core penetrates through the upper valve seat; the upper part of the outer wall of the valve core isinserted into a balance hood; the balance hood is fixedly mounted on the valve body through the valve cover arranged above the balance hood; a filler box is arranged at the upper part of the valve cover; and a valve rod is connected with the middle position of the upper part of the valve core. The balanced three-way shut-off regulating valve disclosed by the invention has the following beneficialeffects: the accurate regulating operation can be achieved by adopting the corresponding overflow hole form according to the working condition demand; through the valve core, the light-weight and convenient opening and closing operation can be achieved; through the plane sealing form, the shut-off and stroke stability can be achieved; and through the guiding filler form, the valve running resistance can be further reduced and the reliability can be improved.
Description
technical field [0001] The invention relates to a control valve, in particular to a balanced three-way cut-off control valve with cut-off and regulation functions. Background technique [0002] At present, the three-way valves on the market mainly realize diversion and confluence and certain adjustment functions. When one end of the three-way pipeline is out of service, it must be cut off by the shut-off valve of the pipe network. As a regulating valve, its application conditions are different, and the flow capacity and regulating performance of the valve required by different application conditions are different. The conventional types of regulating valves include quick opening, linear and equal percentage. Therefore, the valve is required to be able to adapt to various Different working conditions realize different spool structure types. The current three-way regulating valve cannot meet the above requirements at the same time. Contents of the invention [0003] Aiming...
