Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a high-wear-resistant and low-leakage rotary flow direction switching valve. Background Art
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. 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. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc. according to their materials.
[0003] Valves usually include but are not limited to: four-way valves. In construction machinery such as excavators and cranes, four-way valves are used to control the flow direction of hydraulic oil to achieve precise motion control of the equipment. In heat pump air-conditioning systems, four-way reversing valves switch between cooling and heating modes by changing the flow direction of refrigerant. In water treatment systems, four-way valves are used to control the direction and distribution of water flow to achieve water purification and recycling.
[0004] In the prior art, the rotary flow direction switching valve used to control the four-way valve has a slow adjustment rate when adjusting the valve. In production lines that require rapid switching of fluid flow directions, such as in the chemical and pharmaceutical industries, the slow adjustment speed will directly lead to an extension of the production cycle and affect overall production efficiency. In systems that frequently adjust the fluid flow direction, the slow adjustment speed will increase the instability of the system, which may cause fluctuations and uncertainties in the production process. At the same time, due to the slow adjustment speed, the valve may be in a non-ideal working state for a long time, increasing the wear and failure risk of the valve and increasing the frequency and cost of maintenance.

[0027] It should be noted that: the connecting workpiece 2 is used as a connecting tool between the valve body 1 and the shell 3, and is bolted to the valve body 1 through bolts at the bottom to ensure stability during connection. The motor 401 is fixedly installed inside the shell 3 to ensure the stability of the motor 401. When the motor 401 starts working, it drives the crankshaft 402 to rotate. Through the sliding connection between the crankshaft 402 and the first slider 403, when the crankshaft 402 starts to rotate, the first slider 403 is used to convert the rotational motion into reciprocating linear motion. The first slider 403 pushes the connecting rod 404, and the connecting rod 404 drives the sleeve 405 to slide downward.
