Cavitation-resistant angle valve designed by combining sleeve with multi-stage rotary flow channel

Abstract

The utility model relates to the technical field of valves, in particular to an anti-cavitation angle valve with the design that a sleeve is combined with a multi-stage rotary flow channel. According to the anti-cavitation angle valve designed by combining the sleeve with the multi-stage rotary flow channel, a main sleeve is arranged in a valve body, a valve element assembly is arranged in the main sleeve, a throttling sleeve is arranged in a mounting space at the top end of the interior of the main sleeve, and the valve element assembly sequentially penetrates through a center hole of the throttling sleeve and the interior of the main sleeve from top to bottom; clearance fit and installation guidance are formed on the side surface in the main sleeve; the main sleeve and the valve element assembly form a multi-stage rotary pressure reduction flow channel. An outlet of the throttling sleeve is communicated with the multi-stage rotary depressurization flow channel; when the valve element assembly moves upwards, the valve inlet, the throttling sleeve, the multi-stage rotary pressure reduction flow channel and the valve outlet are sequentially communicated. The angle valve is low in cost and convenient to adjust, maintain and replace quickly.
