Throttle regulation valve and production process thereof

Abstract

The invention discloses a throttle regulation valve. The throttle regulation valve comprises a valve body, wherein the left end of the valve body is connected with a first companion flange through a first bolt assembly; a gear stand is mounted at the right end of the valve body through a hexagon socket screw; a driven gear is mounted in the middle of the interior of the gear stand and is in meshed connection with a driving gear; and the driving gear is positioned on the upper side of the interior of the gear stand. According to the throttle regulation valve, the driving gear is operated through rotation to drive the driven gear, so that the position, corresponding to an eccentric hole in the gear stand, of the driven gear is changed, a channel, in which a medium flows, in a pipeline is changed, and accordingly, the flow rate in the pipeline is changed; a striking switch sign scale line is arranged on a switch indicator, and throttling can be visually operated and controlled through the switch indicator; as the throttle regulation valve is designed by adoption of the gear transmission principle, the throttle regulation valve is particularly steady and quick in flow regulation process; and the operation is short in journey and convenient and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of regulating valves, and in particular relates to a throttling regulating valve, and also relates to a production process of the throttling regulating valve. Background technique [0002] At present, there are many types of valves for controlling and regulating pipeline flow sold in the domestic market, such as the most commonly used throttle orifice, globe valve flow regulating valve, flow balancing valve, etc., these valves can be adjusted and adjusted coarsely and precisely. Control the medium flow in the pipeline, but most of these products are only suitable for land use conditions. For the special medium pipeline of marine engineering projects, the flow regulating series valves used in the pipeline are basically imported at present. Our design and manufacture of this kind of throttling adjustment is developed for this market opportunity and demand. For customers, it is a cooperation of "sending carbon ...
