Valve with auxiliary replacement mechanism

Abstract

The invention provides a valve with an auxiliary replacement mechanism, and relates to the technical field of valves. The problems that in the actual application process of an existing valve, when the valve is replaced with water, a main valve of a water pipe generally needs to be closed, otherwise, the valve cannot be smoothly installed due to the fact that the water pressure in the pipe is too large, water resources are wasted, and auxiliary replacement cannot be carried out when the valve is replaced are solved. The valve comprises a flow limiting mechanism, and the flow limiting mechanism is installed on the top side of the interior of a bearing mechanism. According to the valve, the water pipe in an external connection mechanism can be installed on the outer sides of two connecting pipes through flanges B, a flow limiting pipe is connected to the interior of the water pipe in an embedded mode, a replacement waterproof mechanism is installed in the flow limiting pipe, and two driving bevel gears with the same size are coupled into a protection pipe through a guide shaft.

Description

technical field [0001] The invention belongs to the technical field of valves, and more specifically relates to a valve with an auxiliary replacement mechanism. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are the control components in the fluid delivery system. They have 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 range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications. The valves can be used to control the flow of various types of fluids such as ai...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a valve with an auxiliary replacement mechanism to solve the existing problems in the actual application process of the existing valves. When replacing the valve with water, it is generally necessary to first place the main valve of the water pipe on the pipe wall. Otherwise, due to the excessive water pressure in the pipe, the valve cannot be installed smoothly and water resources are wasted, and it is also the problem of auxiliary replacement when the valve cannot be replaced.
