Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valves, in particular to a stop valve with improved rust prevention effect. BACKGROUND

[0002] The stop valve is a tool for controlling the communication and interruption between pipelines. The application of the stop valve is usually related to the transmission of liquid. The transmission screw of the conventional stop valve penetrates the cavity formed by the valve cover and the valve seat to control the movement of the valve plate, thereby controlling the communication. When the valve plate is lifted and placed in the valve structure cavity, water stains or even corrosive liquids on the surface of the valve plate are easy to flow into the valve structure cavity. Long-term water stains and corrosion cause the inner wall of the structure cavity and the surface of the screw to rust, affecting the transmission. Meanwhile, the conventional stop valve screw has an exposed end in the external environment, which is easily affected by the environment and thus rusts or even becomes rusted and cannot be twisted.

[0013] The beneficial effects of the present application are as follows:

[0014] The improved rust-proof effect stop valve of the present application is provided with a functional rust-proof structure, a surrounding rust-proof device is mounted on the top of the valve cover, the functional screw rod shell is used to realize the surrounding effect of the exposed screw rod outside the valve cover, so as to avoid the problem that the exposed part of the transmission screw rod and the connection end of the valve cover are rusted or even rusted to death and cannot be twisted in the humid or outdoor environment for a long time. The problem of water corrosion, meanwhile, the lower side of the handle is provided with a matching sealing structure, the functional telescopic structure is used to realize the butt joint sealing of the sealing butt joint ring and the top sealing groove of the functional screw rod shell after the valve is adjusted and used, so as to realize the shielding of the exposed part of the screw rod between the screw rod shell and the handle, and the sealing effect of the external transmission structure of the valve cover is realized, so as to avoid the problem that the humid gas enters the valve structure cavity through the thread structure and causes corrosion and rust.

[0015] The improved rust-proof effect stop valve of the present application is provided with a functional rust-proof structure, which realizes sealing and surrounding effect on the exposed drive structure outside the valve cover through the cooperation of the sealing structure carried on the lower side of the functional screw rod shell and the handle, thereby avoiding the influence of the external environment on the valve structure cavity and the drive parts from rusting. Meanwhile, the sealing ring cover is filled with rust-proof oil in the sliding cavity of the sealing sliding cylinder, and the sealing sliding cylinder and the functional screw rod shell have an oil transmission structure. Thus, by pressing the handle, the sealing ring cover and the sealing sliding cylinder are relatively displaced, the rust-proof oil in the sliding cavity enters the functional screw rod shell along the transmission structure, and the drive screw rod is coated with oil by the internal adhesive cotton, thereby further improving the sealing and moisture-proof performance. Meanwhile, the handle drives the screw rod to rotate and lift, thereby realizing oil layer coating effect on the outer wall of the screw rod during rotation, so that the drive screw rod placed inside can also obtain rust-proof effect and avoid internal rusting, which causes the screwing performance to decrease or even be unable to screw.

[0016] The improved rust-proof effect stop valve of the present application is provided with a functional rust-proof structure. The control of the pipeline is realized by the lifting of the valve plate inside the stop valve, and the surface of the valve plate will have a liquid in-pipe entering structure cavity during the lifting process, thereby easily causing humidity change in the structure cavity and leading to internal structure rusting. During the lifting process of the valve plate driven by the screw rod, the two elastic outer convex structures carried on the inner wall of the structure cavity bottom side are attached to the rubber pad, thereby realizing the attachment and water stain removal effect of the valve plate by the two attached rubber pads during the lifting of the valve plate into the structure cavity, thereby avoiding the problem of rusting in the cavity caused by the liquid brought out and achieving the surface treatment of the valve plate to avoid the influence of surface stains on the sealing effect of the valve.

For ease of description, the directions referred to below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of the projection relationship are consistent in all directions: up, down, left, right, front, and back.

[0024] Combined with appendix Figures 1-4 The improved rust-preventing shut-off valve includes a valve body 11 with a communicating cavity 12. A valve cover 14 is mounted on the valve body 11, and a valve structure cavity 17 is provided between the valve cover 14 and the valve body 11. A transmission screw 28 is rotatably mounted within the valve structure cavity 17, and a transition block 36 is rotatably mounted on the transmission screw 28. A valve plate 13 is mounted on the transition block 36. Symmetrical embedded grooves 30 are provided on the inner walls of both sides of the valve structure cavity 17. A slidable embedded plate 31 is mounted in each embedded groove 30, and an adhesive pad 32 is mounted on each embedded plate 31. An isolation plate 18 is mounted in the valve structure cavity 17, and a moisture-proof gasket 19 is mounted on the isolation plate 18. A surrounding rust-preventing structure 15 is mounted on the valve cover 14. The surrounding rust-preventive structure 15 includes a functional screw housing 20, in which the transmission screw 28 is rotatably mounted. A permeable ring 22 capable of discharging rust-preventive oil is installed within the functional screw housing 20. A permeable gasket 21 is installed in the permeable ring 22. The functional screw housing 20 has a mating ring groove 45. A sliding handle 29 is installed at the end of the transmission screw 28. A sealing ring cover 24 is installed in the handle 29.

[0025] When working, the valve plate 13 is placed in the communication cavity 12 by rotating the transmission screw 28 to achieve the cutoff effect. When communication is needed, the transmission screw 28 is rotated by rotating the handle 29 to drive the valve plate 13 to move upward. During the movement, the adapter block 36 moves upward to make the adhesive rubber pad 32 move out of the position of the valve plate 13 under the push of the sliding rod 34, so that the liquid on the surface of the valve plate 13 is discharged downward by extrusion. At the same time, when the valve plate 13 is placed in the valve structure cavity 17, the convex end of the adhesive rubber pad 32 is fully attached to the concave end of the valve plate 13 to achieve the sealing effect, thereby avoiding the problem of moisture in the valve structure cavity 17 caused by the upward movement of the valve plate 13. Before the rotation and lifting process, the handle 29 can be pressed once to make the functional sliding ring 41 move upward in the oil filling sliding cavity 38, so that the rust-proof oil in the oil filling sliding cavity 38 is transmitted through the extrusion oil pipe 43 and the transmission groove 46, and then output to the permeation ring pad 21 through the permeation hole ring 22, thereby achieving the effect of oil layer coating on the transmission screw 28 during the subsequent rotation of the handle 29, thereby avoiding the problem of rust on the surface of the transmission screw 28 due to long-term placement. At the same time, it can also play a role in rust prevention for the parts of the transmission screw 28 that are difficult to coat inside. When the valve adjustment is completed, the sealing ring 44 at the end of the sealing sliding cylinder 42 is connected to the connecting ring groove 45 to make the sealing ring cover 24 cooperate with the extrusion oil pipe 43 to fully seal the exposed parts of the functional screw shell 20 and the transmission screw 28, and the permeation ring pad 21 is more attached to the transmission screw 28 after oil permeation, thereby achieving the sealing effect, thereby avoiding the problem of rust caused by the entry of humid air through the thread structure.
