Description

Technical Field

[0001] The utility model provides a rust-proof stop valve, belonging to the technical field of stop valves. Background Art

[0002] A globe valve is a forced-seal valve that relies on stem pressure to tightly seal the disc and seat, preventing the flow of media. In power plant piping systems, it is primarily installed on high-temperature, high-pressure steam and water pipelines with a diameter of 100 mm or less. It consists of a valve body, bonnet, bonnet gasket, and stem. It is widely used in industries such as chemical, pharmaceutical, light industry, papermaking, metallurgy, textile, natural gas, municipal engineering, food, shipbuilding, and electric power.

[0003] Currently, the valve body, valve stem, and handwheel of the stop valve are mostly made of metal materials, which will rust after long-term use. In particular, stop valves used outdoors lack rainproof structures. Once it rains, the valve body, valve stem, and handwheel are often directly exposed to rainwater, which in turn corrodes the valve body, valve stem, and handwheel, accelerating the rusting of the valve body, valve stem, and handwheel. Based on this, the utility model provides a rust-proof stop valve. Utility Model Content

[0004] The technical problem solved by the utility model is that rust will occur after long-term use, especially for stop valves used outdoors. Due to the lack of rainproof structure, once it rains, the valve body, valve stem and hand wheel are often directly exposed to rainwater, and then eroded by the rainwater, which accelerates the rusting of the valve body, valve stem and hand wheel.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a rust-proof stop valve, including a valve body, a valve stem is provided on the top of the valve body, a handwheel is provided on the top of the valve stem, a support seat is symmetrically provided on one side wall of the valve body, the side wall of the support seat is rotatably connected to a support rod, a baffle is provided between the tops of the support rods and placed above the handwheel for sheltering from rain, a locking assembly is provided on the lower side wall of the support rod for cooperating with the top of the support seat for locking the baffle position, and the outer walls of the valve body, valve stem, handwheel and baffle are all coated with anti-rust paint.

[0006] Furthermore, the locking assembly includes a hollow block arranged on the lower wall of the support rod side, a slide is slidably connected to the hollow block, a locking rod is symmetrically provided at the bottom of the slide, which passes through the bottom of the hollow block and is inserted into the top of the support seat, the top of the slide is provided with a connecting rod passing through the top of the hollow block, the top of the connecting rod is provided with a handle, and the connecting rod is sleeved with a reset spring placed between the top wall inside the hollow block and the top wall of the slide.

[0007] Furthermore, the top of the support seat is symmetrically provided with locking holes that match the locking rod.

[0008] Furthermore, the two inner side walls of the hollow block are symmetrically provided with slide rails that match the side walls of the slide plate.

[0009] Furthermore, a connecting seat is provided at the bottom of the support rod, and the side wall of the connecting seat is rotatably connected to the side wall of the support seat through a rotating rod.

[0010] Furthermore, a handle is provided on the top of the baffle.

[0011] Beneficial effects of the utility model:

[0012] The valve body, stem, handwheel and baffle are sprayed with anti-rust paint to prevent rust. The baffle is locked directly above the handwheel through the locking assembly. When it rains when used outdoors, it can protect the valve body, stem and handwheel from being directly exposed to rain, so as to avoid erosion by rain and accelerated rust. When the handwheel needs to be turned or the stem is damaged and needs to be repaired or replaced, the locking assembly is disconnected from the support seat, and the handle is held to flip the baffle to the side of the valve body, so that the stem, handwheel and other parts on the stop valve can be easily repaired and replaced.

[0024] According to the attached Figure 1 As shown: a handle 18 is provided on the top of the baffle 6 to facilitate operation.

[0025] Principle of the utility model

[0026] When in use, anti-rust paint is sprayed on the outer walls of the valve body 1, valve stem 2, hand wheel 3 and baffle 6 to achieve rust prevention. Through the locking assembly 7, the handle 12 is held and pulled upward, thereby driving the connecting rod 11, slide plate 9 and locking rod 10 to move upward. At this time, the return spring 13 is under force and is in a compressed state. Under the action of the rotating rod 17, the support rod 5 is flipped, so that the baffle 6 is flipped to the top of the valve body 1, valve stem 2 and hand wheel 3, ensuring that the locking rod 10 is connected with the locking hole 14. Release the handle 12, and the compressed return spring 13 rebounds and resets, driving the connecting rod 11, slide plate 9 and locking rod 10 to move downward, thereby inserting the locking rod 10 into the locking hole 14. At this time, the support rod 5 and baffle 6 are locked, and the baffle 6 can be locked just above the hand wheel 3 through the locking assembly 7. When used outdoors and encountering rain, it can play a role in sheltering from rain, effectively preventing the valve body 1, valve stem 2 and hand wheel 3 from being directly exposed to rain water, so as to avoid erosion by rain water and causing rust.

[0027] When the handwheel needs to be turned or the valve stem is damaged and needs to be repaired or replaced, by disconnecting the locking assembly 7 from the support seat 4 and holding the handle 18 to flip the baffle 6 to the side of the valve body 1, it is convenient to repair and replace the valve stem 2, handwheel 3 and other parts on the stop valve. Through the locking assembly 7, hold the handle 12 and pull it upward, thereby driving the connecting rod 11, the slide plate 9, and the locking rod 10 to move upward until the locking rod 10 is removed from the locking hole 14, and then disconnect the locking assembly 7 from the support seat 4, hold the handle 18 to flip the baffle 6 to the side of the valve body 1, which is convenient to repair and replace the valve stem 2, handwheel 3 and other parts on the stop valve.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
