Description

Technical Field

[0001] The utility model relates to the technical field of valve protection, in particular to a valve stem protective cover for a valve. Background Art

[0002] In industrial production and daily life, globe valves are widely used as common valves. However, most current globe valves are directly exposed to the air, especially the valve stem part. In a humid environment, the valve and the valve stem are extremely prone to rust. This not only affects the appearance of the valve, but more seriously threatens its normal use function, reduces the service life of the valve, and increases the maintenance cost.

[0003] Currently, in practical applications, in order to protect the globe valve, people often use methods such as covering it with a plastic bag or a foam box. However, this kind of protective measure has many drawbacks. On the one hand, it is not firm and is easily blown open by the wind or damaged by slight external force, making it difficult to achieve a good protective effect. On the other hand, although there are some more complex protective structures that can wrap the valve more tightly, they are difficult to remove when the valve needs to be used, bringing inconvenience to users. Summary of the Utility Model

[0004] The utility model proposes a valve stem protective cover for a valve that is strong, durable, has a good protective effect, is easy to remove and reuse to solve the above various problems.

[0005] To solve the above technical problems, the technical solution proposed by the utility model is: a valve stem protective cover for a valve, comprising:

[0006] Protective shells, there are two protective shells and they are symmetrically arranged on both sides of the upper end of the valve. The two protective shells are butt-jointed and fixed through a tightening ring;

[0007] A shielding cover, which is snap-connected to the upper end of the protective shell;

[0008] A protective strip, which is wrapped around the outside of the valve stem.

[0009] Further, the upper ends of the two protective shells form an inverted cone shape, and the lower ends form a cylindrical shape.

[0010] Based on the above characteristics, the inverted cone-shaped protective shell is adapted to the shape of the valve, which can better play a protective role. The cylindrical lower end is more tightly connected to the valve stem, improving the sealing performance of the protective cover and further enhancing the protective effect on the valve.

[0011] Further, the tightening ring is made of an elastic material. Tightening rings are provided at both the upper and lower ends of the protective shell, and limiting grooves for cooperating with the tightening rings are provided on the side walls of the protective shell.

[0012] Based on the above characteristics, the tightening ring made of elastic material can adapt to valves and valve stems of different sizes, improving the versatility of the protective cover and facilitating quick disassembly and assembly. Tightening rings are provided at both the upper and lower ends of the protective housing and cooperate with the limiting grooves on the side walls, ensuring the stable fixation of the tightening ring to the protective housing and guaranteeing the stability of the protective cover during use, thereby achieving a good protective effect.

[0013] Furthermore, the shielding cover includes a cover plate and a clamping block integrally formed below the cover plate, and a clamping groove for cooperating with the clamping block is provided at the upper end of the protective housing.

[0014] Based on the above characteristics, the clamping block and the clamping groove cooperate with each other, enabling the quick installation and disassembly of the shielding cover, which is convenient and practical.

[0015] Furthermore, the diameter of the cover plate is larger than that of the protective housing, and the upper wall edge of the cover plate is an arc surface inclined downward.

[0016] Based on the above characteristics, the cover plate can effectively shield and protect the protective housing, preventing rainwater from entering the interior of the protective housing through the gaps between the protective housings and eroding the valve, and the arc surface design of the cover plate edge can guide liquids such as rainwater to flow down smoothly, avoiding accumulation on the protective cover, thereby reducing corrosion and damage to the protective cover.

[0017] Furthermore, adhesive pads that cooperate with each other are provided at both ends of the protective strip, and the adhesive pads are respectively arranged on the front and back sides of the protective strip.

[0018] Based on the above characteristics, the adhesive pads arranged on the front and back sides of the protective strip can enable the protective strip to stably wrap around the outside of the valve stem, achieving effective protection.

[0019] Furthermore, an anti-sticking sheet is provided on the side of the adhesive pad away from the protective strip.

[0020] Based on the above characteristics, the anti-sticking sheet can prevent the adhesive pad from being contaminated or adhered to other objects when not in use, maintaining the adhesiveness of the adhesive pad and ensuring that the protective strip can be firmly fixed on the valve stem.

[0021] The advantages of the present utility model compared with the prior art are as follows:

[0022] Sturdy and durable with good protective effect: There are two protective housings symmetrically arranged on both sides of the upper end of the valve and fixed by tightening rings, which can ensure that the protective housing is stably arranged around the valve for protection, preventing the protective housing from loosening or falling off, being sturdy and durable. The valve stem is wrapped with a protective strip for protection, which can achieve full protection of all parts of the valve. A shielding cover is arranged above the protective housing, which can effectively block impurities such as dust and rainwater from entering the valve stem part, and has a good protective effect.

[0023] Easy to disassemble and reuse: The two protective shells are butt-jointed and fixed through a tightening ring made of elastic material. When the protective cover needs to be removed, only the tightening ring needs to be loosened and the shielding cover can be taken off; the shielding cover is snap-connected to the protective shell and can be easily snapped in for installation and pulled out for disassembly, with convenient and fast disassembly and assembly; the protective strip is wound around the outside of the valve stem and adhesively bonded at the head and tail through an adhesive gasket. The installation and disassembly of the protective strip can be easily achieved through the adhesion and separation of the adhesive gasket, and each step does not damage the structure, facilitating reuse.
