Description

Technical Field

[0001] This utility model relates to the field of valve protection equipment, and in particular to an outdoor valve protection device. Background Technology

[0002] Current outdoor valves include rising stem gate valves and non-rising stem gate valves. In rising stem gate valves, the valve stem is exposed on the outside of the handwheel. In humid and rainy areas, the exposed valve stem is prone to rust and dust accumulation, leading to frequent malfunctions. Existing valve sleeves, valve covers, and other valve protection devices are bulky, making operation inconvenient when installed on rising stem gate valves. Furthermore, these devices are often made of opaque materials, hindering operators' ability to observe the valve's opening and closing status.

[0003] Therefore, how to provide an outdoor valve protection device that is small in size and easy for operators to observe the opening and closing status of the rising stem gate valve has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to provide an outdoor valve protection device that solves the problem that existing outdoor valve protection devices are bulky and inconvenient for operators to observe the opening and closing status of rising stem gate valves.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides an outdoor valve protection device, including a valve stem cover and a disc component. The disc component is installed on the side wall of the valve stem cover, which is installed on the top of the valve stem of a rising stem gate valve. The inner diameter of the valve stem cover matches the diameter of the valve stem. The disc component is located above the handwheel of the rising stem gate valve, and the diameter of the disc component is not less than the diameter of the handwheel of the rising stem gate valve. Both the valve stem cover and the disc component are made of transparent material.

[0007] Optionally, when the rising stem gate valve is closed, the distance between the bottom end of the disc component and the top end of the handwheel of the rising stem gate valve is 5-7 cm.

[0008] Optionally, the valve stem cover includes a cylinder and a cover, the cylinder being threaded onto the valve stem, the cover being threaded onto the top of the cylinder, and the length of the cylinder matching the length of the valve stem.

[0009] Optionally, a horizontally arranged perforated baffle is installed inside the cover, and a bagged desiccant is placed on the perforated baffle.

[0010] Optionally, the disk component may include a first disk that is planar, a second disk that is frustum-shaped, or a third disk that is umbrella-shaped or wavy.

[0011] Optionally, an oil outlet hole is provided on the side wall of the cylinder, and an oil baffle rod is snapped onto the oil outlet hole, which is located above the third disc.

[0012] Optionally, a rubber gasket is fitted around the outer side of the disc to prevent finger cuts.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This equipment is smaller in size than existing valve barrel covers, making it easier to operate. Furthermore, the equipment is made of transparent material, allowing operators to easily observe the opening and closing status of the rising stem gate valve. Attached Figure Description

[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figure 1-11 As shown, an outdoor valve protection device includes a valve stem cover 1 and a disc component 2. The disc component 2 is installed on the side wall of the valve stem cover 1. The valve stem cover 1 is installed on the top of the valve stem of a rising stem gate valve. The inner diameter of the valve stem cover 1 matches the diameter of the valve stem. The disc component 2 is located above the handwheel of the rising stem gate valve. The diameter of the disc component 2 is not less than the diameter of the handwheel of the rising stem gate valve. Both the valve stem cover 1 and the disc component 2 are made of transparent material.

[0030] This equipment is smaller in size than existing valve barrel covers, making it easier to operate. Furthermore, the equipment is made of transparent material, allowing operators to easily observe the opening and closing status of the rising stem gate valve.

[0031] In specific implementation, the diameter of the disc component 2 is 2cm larger than the diameter of the handwheel of the rising stem gate valve.

[0032] Specifically, both the valve stem cover 1 and the disc component 2 are made of acrylic sheet.

[0033] Specifically, when the rising stem gate valve is closed, the distance between the bottom end of the disc component 2 and the top end of the handwheel of the rising stem gate valve is 5-7 cm, so that the operator can rotate the handwheel of the rising stem gate valve.

[0034] Specifically, the valve stem cover 1 includes a cylinder 11 and a cover 12. The cylinder 11 is threaded to the valve stem, and the cover 12 is threaded to the top of the cylinder 11. The length of the cylinder 11 matches the length of the valve stem.

[0035] The bottom of the cylinder 11 is provided with an internal thread, and the top of the cylinder 11 is provided with an external thread. The internal thread at the bottom of the cylinder 11 and the external thread at the top of the cylinder 11 are matched. When the length of the cylinder 11 is insufficient, an additional cylinder 11 can be added on the basis of the original cylinder 11. The cover 12 is threaded to the topmost cylinder 11. The above configuration makes it easy for this equipment to adapt to gate valves of different lengths.

[0036] Specifically, a horizontally arranged perforated baffle 121 is installed inside the cover 12, and a bagged desiccant is placed on the perforated baffle 121, wherein the desiccant is used to further reduce the risk of valve stem rusting.

[0037] Specifically, the disc component 2 includes a first disc 21 in a planar shape, a second disc 22 in a frustum shape, or a third disc 23 in an umbrella-shaped wave shape.

[0038] In practical applications, existing valve protection devices such as valve sleeves or valve barrel covers are prone to birds and animals building nests. Setting the disc component 2 as a second disc 22 in the shape of a frustum or a third disc 23 in the shape of an umbrella wave can help solve the problem of birds and animals building nests.

[0039] Specifically, an oil outlet hole 111 is provided on the side wall of the cylinder 11, and an oil baffle rod is snapped onto the oil outlet hole 111. The oil outlet hole 111 is located above the third disc 23.

[0040] In practice, when the handwheel of the rising stem gate valve is difficult to turn, the cover 12 can be opened and lubricating oil can be poured into the cylinder 11. Then, the oil baffle rod can be opened. After soaking the valve stem, the lubricating oil will flow out from the oil outlet 111. When the lubricating oil flows onto the umbrella-shaped wave-like third disc 23, it will continue to flow outward from the groove between two adjacent waves on the third disc 23. The operator can collect the lubricating oil by placing an oil storage bottle on the outer edge of the groove of the third disc 23.

[0041] Specifically, a rubber gasket is fitted around the outer side of the disc component 2 to prevent finger cuts.
