Description

Novel protective cover for valve

Technical Field

the utility model relates to a novel protection casing is used to valve.

Background

The valve is a control part in a fluid conveying system, has the functions of stopping, flowing backwards, preventing counter flow, stabilizing pressure, shunting, overflowing, relieving pressure and the like, and is used for a valve of the fluid control system. The variety and specifications of the valves used range from the simplest shut-off valves to the most sophisticated autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like.

The valves are further classified into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, and the like according to the material. Since the use of the valve is widespread, it also plays a great role. For example: valves are used in power plants to control the operation of boilers and turbines; in the petroleum and chemical production, the valve also controls the normal operation of all production equipment and process flows. This is also true in other departments. However, valves are often overlooked by people compared to other products. For example: when installing machine equipment, people often focus on the main machine equipment, but neglect the valve. This may result in a reduction in overall production efficiency or a stoppage of production, or various other accidents. Therefore, the selection, installation, use, etc. of the valve must be carefully handled.

The valve is often exposed outside, and the plastic bag is used for protecting the valve in the market at present, so that the valve is prevented from being damaged and corroded, but the plastic bag is easy to age and damage due to the influence of external factors, so that the valve is large in loss, and the valve cannot be protected if the plastic bag is not replaced in time.

Therefore, the chinese utility model patent with the publication number CN206694627U discloses a valve protection cover, which is a truncated cone structure with an open lower end and a small upper part and a large lower part, comprising a top plate at the upper end and a surrounding plate arranged at the outer edge of the lower end surface of the top plate, wherein the inside of the surrounding plate is a protection cavity, a connecting hole penetrating up and down is arranged in the middle of the top plate of the protection cover, the inner hole edge of the connecting hole extends downwards to form a connecting cylinder with a cylindrical structure, the inner wall of the connecting cylinder is provided with a fixing sleeve made of elastic material, the protection cover comprises a left cover body and a right cover body which are spliced in bilateral symmetry, two sides of the left cover body and the right cover body are respectively provided with two corresponding connecting lugs, the connecting lugs are provided with connecting through holes, and the; the connecting hole, the connecting cylinder and the fixed sleeve are equally divided by the left cover body and the right cover body. This valve protection casing can effectively reduce valve corrosion degree, but when the valve was in the lower operational environment of temperature, this valve protection casing can not play fine guard action to the valve, and the valve is easily damaged by freezing.
