Abstract

The invention belongs to the field of control valves, and specifically relates to an air cylinder control valve. The air cylinder control valve comprises a two-way adjusting valve, a sealing pressingpiece, a limiting ring, an adjustable elastic moving part and an electric telescopic rod, wherein an operating rod of the two-way adjusting valve moves downwards in an axial direction in an operatingstate, and the two-way adjusting valve is open; the sealing pressing piece is arranged in the top end of the two-way adjusting valve, and the operating rod of the two-way adjusting valve is in slidingseal fit with the sealing pressing piece coaxially; the limiting ring is coaxially arranged on the top end of an operating shaft of the two-way adjusting valve; the adjustable elastic moving part iscoaxially arranged on the top end of the sealing pressing piece, and the limiting ring is coaxially located on the elastic abutting end of the interior of the adjustable elastic moving part; and the electric telescopic rod and the sealing pressing piece are coaxially arranged on the top end of the two-way adjusting valve by virtue of a fixed frame, and an output shaft of the electric telescopic rod coaxially penetrates through the top end of the adjustable elastic moving part and is coaxially and fixedly connected with the top end of the limiting ring. The air cylinder control valve has the advantage of a stable structure, and the flow speed of air can be adjusted.

Description

technical field [0001] The invention relates to the field of control valves, in particular to a cylinder control valve. Background technique [0002] The cylinder control valve is a very important terminal component in the automatic control system. It is used to adjust the gas flow to the cylinder. The actuator of the control valve can withstand high air source pressure, large thrust, fast stroke speed, and is durable. Cylinder output shaft extension rates can be varied by a control valve capable of adjusting the gas flow rate. [0003] Chinese patent CN201620946783.7 discloses a cylinder-type straight-through control valve, which includes a valve body and a valve core. There is a liquid chlorine flow channel in the valve body, and inlets and outlets connected to the liquid chlorine flow channel are arranged on both sides of the valve body. The valve core Including the valve core body and the valve seat, the horizontally placed U-shaped valve seat is installed in the middle...
