<p>A hydraulic spiral stop valve, comprising a valve body (1) and a valve disk (2); the valve disk (2) is connected to a valve rod (3); the valve rod (3) is connected to a screw rod driven by a hydraulic spiral device. The hydraulic spiral stop valve has a reasonable structure, and drives a screw sleeve to rotate via a bevel gear conversion mechanism, thus realizing the opening and closing of the valve. The hydraulic spiral stop valve has the advantages of stable operation, large torque, low noise, hermetically sealed engaging part, and high degree of protection.</p> |
