Pressing type throttling ball valve

Abstract

The invention discloses a pressing type throttling ball valve. The pressing type throttling ball valve comprises a valve body, a valve cavity is formed in the valve body, the valve cavity is providedwith a water inlet and a water outlet, a ball valve main body is arranged in the valve body, and a control device is arranged on the ball valve main body. The pressing type throttling ball valve is characterized in that a main flowing channel and a throttling channel which communicate with each other are arranged in the valve element, and the control device controls the main flowing channel or thethrottling channel to communicate with the water inlet and the water outlet; a time-limited throttling device is arranged in the throttling channel and comprises a first rack and a second rack, and the first rack and the second rack are connected through a permanent magnet in a sealing mode; and the control device controls the first rack and the second rack to separate to open the throttling channel. According to the pressing type throttling ball valve, two output modes can be freely switched, throttling can be effectively achieved in a pressing type water outlet mode, and the service life ofa sealing part can be prolonged.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a push-type 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] And as the use time increases, the seal and t...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a push-type throttling ball valve to solve the problem that the ball valve in the prior art cannot achieve throttling and save water in the second half of the push-type water outlet, as well as the problem of wear and tear of the sealing ring during use.
