Abstract
The utility model discloses a hydraulic spiral stop valve which comprises a valve block and a valve disk. The valve disk is connected with a valve stem which is connected with a screw driven by a hydraulic spiral device. The hydraulic spiral stop valve is reasonable in structure, and a screw sleeve is driven to rotate by a bevel gear conversion mechanism so as to turn on or off the valve. The hydraulic spiral stop valve is stable to operate, large in torque and low in noise, a combining part is sealed, and IP (ingress protection) 65 is high.
Description
Technical field
The utility model relates to a kind of stop valve, is a kind of for the valve in the bulk goods wheel collision bulkhead.
Background technique
Valve in the existing bulk goods wheel collision bulkhead adopts piston structure or gear rack straight journey mechanism valve, has the problems such as noise is large, smoothness of operation is not good enough.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the spiral stop valve that surges of favorable working performance.
Technical solution of the present utility model is:
A kind of spiral stop valve that surges comprises valve body, valve disc, and valve disc is connected with valve rod, it is characterized in that: valve rod is connected with the screw rod that the screw that surges drives.
The described screw that surges comprises hydraulic jack, and the piston rod of hydraulic jack is connected with bevel gear switching mechanism, and bevel gear switching mechanism is connected with the swivel nut that is connected with screw rod.
Dress stem guiding plate on the valve body, valve rod is installed in the pilot hole of stem guiding plate, at valve rod and guide plate contact position the O RunddichtringO is set.
Valve body is connected by intermediate connector with the screw that surges.
Between valve rod and the valve disc gland nut is set.
The utility model is rational in infrastructure, rotates by bevel gear switching mechanism band movable snail sleeve, thus the keying of realization valve.The utility model smooth running, moment of torsion is large, noise is little, and encapsulation process, the large IP65 of security level are adopted in the connecting part.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model structural representation.
