Abstract
The utility model provides an outside screw valve lead screw protecting device, which comprises a protective cover casing body, an observation window, a valve hand wheel gland and a lower-portion protective cover, wherein the protective cover casing body is tightly fixedly connected with the valve hand wheel gland; the observation window is arranged on the protective cover casing body; the valve hand wheel gland is fixed onto a valve copper bush; and the lower-portion protective cover installed on a lead screw is movably engaged and connected with the lead screw, and is tightly integrally combined by two semicircular hollow bodies with grooves on two sides. The outside screw valve lead screw protecting device has the advantages of simple structure, convenient use and capabilities of saving manpower, material resources and time and effectively protecting the lead screw from corrosion caused by external factors.
Description
Technical field
The utility model relates to a kind of Machine guarding, especially is a kind of rising stem (RS.) valve protective gear.
Background technique
No matter be outdoor or indoor rising stem (RS.) valve, all can run into the dust foul and stick on the valve leading screw in production reality, particularly outdoor valve makes valve switch dumb owing to be subjected to the erosion of dust storm, rainwater, also brings inconvenience to work.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at existing rising stem (RS.) valve, and provide a kind of and can save human and material resources and time, and the valve protective cap device that can protect leading screw not influenced by foeign element effectively.
The technological scheme that the utility model adopted is: a kind of rising stem (RS.) valve leading screw protective gear, form by safety cover housing, viewing window, valve handle gland and bottom guard shield, the safety cover housing is closely fixedlyed connected with the valve handle gland, has viewing window valve handle gland on the safety cover housing and is fixed on the valve copper sheathing; The bottom guard shield is contained on the leading screw, is connected with the leading screw activity, and the semicircle hollow body of being slotted by two both sides is closely linked.
That the utility model has compared with prior art is simple in structure, easy to use, save human and material resources and time, and can protect leading screw to avoid the advantage of extraneous factor corrosion effectively.
Description of drawings
