Flow regulating valve of high performance water-free hammer

Abstract

The invention discloses a flow regulating valve of a high performance water-free hammer. A disc valve element is arranged at the lower end of a valve shaft in a sleeving manner, the valve element is rotatably and hermetically connected to the valve seat, a first arc-shaped groove is formed in the valve seat, a second arc-shaped groove aligned to the first arc-shaped groove is formed in the valve element, a pressure spring, through which the valve element compresses the valve seat, is arranged between a boss and the valve element in a sleeving manner, the valve shaft stretches upward out of a valve cover and a driven bevel gear is mounted at the stretching end, a cylinder is fixed to a valve body, the lower end of the valve body communicates to an inlet channel, a piston rod is fixed to theupper end of a piston, a rack is fixed to the upper end of the piston rod, a driving bevel gear engaged to the driven bevel gear is mounted on a transmission shaft, and the greater the fluid pressurein the inlet channel is, the areas, aligned to the first and second arc-shaped grooves, are . The size of an opening between the inlet channel and the valve seat is adjusted according to the fluid pressure of the inlet channel, and the response time is short. The pressure spring can overcome relative wear between the valve element and the valve body, so that the sealing property of the flow regulating valve is good.

Description

technical field [0001] The invention relates to the field of screw type hoist equipment, in particular to a novel hoist emergency operator. Background technique [0002] Flow regulating valve, also known as self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, flow balancing valve, is an intuitive and simple flow regulating control device. In the process of conveying high-pressure liquid water flow, plug valves (or ball valves) or flow orifice plates are mostly used to adjust and control the flow of high-pressure liquid, and the automatic adjustment of the flow regulating valve cannot be realized according to the pressure of the liquid flow, or automatic adjustment If the response time is too long, it is difficult to make an effect in time to ensure that the output flow of the regulating valve is relatively stable. During the transmission of high-pressure liquid, at the control valve, the rapid change of fluid flow will cause large pre...
