A flow regulating valve

Abstract

The invention relates to a flow regulating valve, comprising a valve body, a connecting mechanism, a rotating handwheel, a driving mechanism, a connecting end, a threaded connecting rod, a supporting mechanism and a fixing mechanism. The top of the valve body is provided with a connecting mechanism, and the connecting mechanism The upper end of the valve body is equipped with a rotating handwheel, one side of the connecting mechanism is connected with a driving mechanism, both ends of the bottom of the valve body are provided with connecting ends, a threaded connecting rod is welded at the center of the outer wall of the bottom of the valve body, and the outer wall of the threaded connecting rod passes through A support mechanism is installed with the screw thread, the bottom of the support mechanism is connected with a fixing mechanism, the connecting shell is welded on the top outer wall of the valve body, the inner center of the connecting shell is provided with a valve stem, the top of the valve stem is connected with the rotating handwheel, the first cone The gear is welded on the outer wall of the valve stem, one side of the first bevel gear is meshed with a second bevel gear, and one side of the second bevel gear is welded with a rotating shaft. The present invention effectively increases the overall stability of the valve, and at the same time, adjusts the The control process is more convenient and fast.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a flow regulating valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. It is a control component in the fluid conveying system, with the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest globe valves to various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The flow control valve is one of many valves [0003] However, a kind of flow regulating valve currently on the market has the following problems during use. a. Sin...

Problems solved by technology

[0003] However, a kind of flow regulating valve currently on the market has the following problems during use. a. Since the existing flow control valve is partly installed in an outdoor environment, and in order to prevent pipeline pollution and corrosion, the erection of pipelines is suspended The way of erection makes the overall flow regulating valve also in a suspended state, resulting in poor stability of the entire valve. At the same time, when the valve is opened and closed manually, turning the handwheel will drive the connection between the valve and the pipeline to a certain extent. Offset occurs at the position, which is easy to cause damage to the valve; b. Based on the existing valves are opened and closed by handwheel rotation, the operator cannot complete the control work of the team valve conveniently and quickly under certain circumstances
