Abstract

The invention discloses a safety throttling ball valve. The ball valve comprises a valve body 1, a valve cavity is arranged in the valve body 1, the valve cavity is provided with a water inlet 81 anda water outlet 82, the valve body 1 is internally provided with a valve core 2, a control device is arranged on the valve core 2, the ball valve is characterized in that a horizontally-penetrating throttling channel 21 is arranged in the valve core 2, the control device controls the throttling channel 21 to be communicated with the water inlet 81 and the water outlet 82, a time-limiting throttlingdevice is arranged in the throttling channel 21, the time-limiting throttling device comprises a first rack 53 and a second rack 54, and the first rack 53 and the second rack 54 are hermetically connected by a permanent magnet to seal the throttling channel 21; and the control device controls the first rack 53 and the second rack 54 to separate and open the throttling channel 21. The safety throttling ball valve can effectively throttle and prolong the service life of the sealing element, and is provided with a locking mechanism to prevent accidental touch to open the switch.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a safety throttling ball valve. Background technique [0002] Ball valve is a kind of valve that drives the spherical valve core through the valve stem and rotates around the axis of the valve stem. It has a valve body for opening and closing the flow path, and a ball arranged around the valve body. Seat, pressure ring installed on the ball seat; ball valve can also be used for fluid regulation and control, mainly used to cut off or connect the medium in the pipeline, and is widely used in various industries. [0003] The ball valves provided today cannot achieve throttling and flow control, and cannot freely adjust the throttling mode and normal mode. People often only need some high-flow water flow at the beginning, but do not make high use of the second half of the water flow. rate, resulting in a lot of waste. [0004] In some specific occasions and specific water ou...
