[0002] The stop valve is a tool for controlling the connection and interruption between pipelines. The application of the stop valve is usually related to the transmission of liquids. The transmission screw of the conventional stop valve passes through the cavity formed by the valve cover and the valve seat to control the movement of the valve plate, thereby achieving the effect of controlling the connection. When the valve plate is lifted and placed in the valve structure cavity, water stains on the surface of the valve plate and even corrosive liquids are easy to flow into the valve structure cavity. Long-term water stain corrosion causes rust on the inner wall of the structure cavity and the surface of the screw, affecting the transmission. At the same time, the conventional stop valve screw has an exposed end in the external environment, which is easily affected by the environment and rusted or even rusted and cannot be turned.

[0013] Beneficial effects of the present invention:

[0014] The stop valve with improved anti-rust effect of the present invention is provided with a functional anti-rust structure, a surrounding anti-rust device is mounted on the top of the valve cover, and a surrounding effect is achieved on the exposed screw on the outer side of the valve cover through a functional screw shell, thereby avoiding the problem that the exposed part of the transmission screw and the valve cover connection end are rusted or even rusted and cannot be twisted due to long-term water corrosion in a humid or outdoor environment. At the same time, a matching sealing structure is mounted on the lower side of the handle, and the functional telescopic structure is used to achieve a butt seal with the sealing butt ring and the sealing groove on the top of the functional screw shell after the valve adjustment is completed, thereby shielding the exposed part of the screw between the screw shell and the handle, and achieving a sealing effect for the external transmission structure of the valve cover, thereby avoiding the problem that humid gas enters the valve structure cavity through the threaded structure and is corroded and rusted due to it;

[0015] The stop valve with improved rust-proof effect of the present invention realizes the sealing and surrounding effect of the exposed transmission structure on the outer side of the valve cover through the setting of the functional rust-proof structure, and the matching sealing structure carried by the functional screw shell and the lower side of the rotating handle, so as to avoid the problem that the external environment affects the valve structure cavity and the transmission parts to be rusted. At the same time, the sliding cavity of the sealing slide cylinder carried by the sealing ring cover is filled with rust-proof oil, and the sealing slide cylinder and the functional screw shell have an oil transmission structure, so that by pressing the rotating handle, the sealing ring cover and the sealing slide cylinder realize relative displacement, so that the rust-proof oil in the sliding cavity enters the functional screw shell along the transmission structure, and cooperates with the internal bonding cotton to perform the oil coating effect on the transmission screw, thereby further improving the sealing and moisture-proof performance, and at the same time cooperates with the rotating handle to drive the screw to rotate and lift, so that the outer wall of the screw is coated with an oil layer during the rotation process, so as to achieve the effect of applying the screw oil layer once during the rotation of the transmission screw, so that the difficult-to-maintain part of the internal transmission screw can also obtain the rust-proof effect, and avoid the problem that the twisting performance is reduced or even cannot be twisted due to internal rust;

[0016] The stop valve with improved rust prevention effect of the present invention is provided with a functional rust prevention structure. The stop valve controls the pipeline by lifting the valve plate inside. During the lifting process, the surface of the valve plate will carry the liquid in the pipe into the structural cavity, which may easily cause the humidity in the structural cavity to change and lead to rust of the internal structure. In the process of driving the valve plate to lift and lower by the screw, the outer convex structure is elastically mounted on both sides of the inner wall of the bottom of the structural cavity. Therefore, in the process of the valve plate rising and entering the structural cavity, the water stains on the valve plate can be removed by the two fitting rubber pads, thereby avoiding the problem of rust in the cavity caused by bringing out liquid and at the same time treating the surface of the valve plate to avoid stains on the surface that affect the valve sealing effect.

[0023] Combine the following Figure 1-4 The present invention is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front, and back directions mentioned below are the same as Figure 1 The up-down, left-right, front-back directions of the projection relationship itself are consistent.

[0024] Combined with Figure 1-4 The stop valve with improved anti-rust effect comprises a valve body 11, wherein a connecting cavity 12 is arranged in the valve body 11, a valve cover 14 is installed in the valve body 11, a valve structure cavity 17 is arranged between the valve cover 14 and the valve body 11, a driving screw 28 is rotatably installed in the valve structure cavity 17, a transfer block 36 is rotatably installed in the driving screw 28, a valve plate 13 is installed in the transfer block 36, inner walls on both sides of the valve structure cavity 17 are symmetrically provided with embedded grooves 30, a slidable embedded plate 31 is installed in the embedded groove 30, a fitting rubber pad 32 is installed in the embedded plate 31, an isolation sheet 18 is installed in the valve structure cavity 17, a moisture-proof ring pad 19 is installed in the isolation sheet 18, and a surrounding anti-rust structure 15 is installed in the valve cover 14. The surrounding anti-rust structure 15 includes a functional screw shell 20, in which the driving screw 28 is rotatably installed, in which a penetration hole ring 22 capable of outputting anti-rust oil is installed, in which a penetration hole ring 22 is installed, and a penetration ring gasket 21 is installed. The functional screw shell 20 is provided with a docking ring groove 45, and a rotating handle 29 that can slide up and down is installed at the end of the driving screw 28, and a sealing ring cover 24 is installed on the rotating handle 29, and an oil-filled sliding cavity 38 is provided in the sealing ring cover 24, and a functional sliding ring 41 is slidably installed in the oil-filled sliding cavity 38, and the functional sliding ring 41 is installed with a sealing sliding cylinder 42, and a docking sealing ring 44 is installed at the end of the sealing sliding cylinder 42, and the docking sealing ring 44 is placed in the docking ring groove 45.

[0025] During operation, the valve plate 13 is placed in the connecting cavity 12 by rotating the transmission screw 28, thereby achieving a shutoff effect. When communication is required, the turning handle 29 is turned to rotate the transmission screw 28 to drive the valve plate 13 to move upward. During the movement, the adapter block 36 moves upward so that the fitting rubber pad 32 fits the removed position of the valve plate 13 under the push of the fitting slide rod 34, so that the liquid on the surface of the valve plate 13 is discharged downward by squeezing. At the same time, when the valve plate 13 is placed in the valve structure cavity 17, the convex end of the fitting rubber pad 32 and the concave end of the valve plate 13 are fully fitted to achieve a sealing effect, thereby avoiding moisture problems in the valve structure cavity 17 caused by the upward movement of the valve plate 13. At the same time, before the rotation and lifting process, the turning handle 29 can be pressed once to make the functional slip ring 41 push upward in the oil-filled sliding cavity 38, so that the rust-proof oil in the oil-filled sliding cavity 38 can pass. The oil is transmitted through the extrusion oil delivery pipe 43 and the transmission groove 46, and then output to the penetration ring pad 21 through the penetration hole ring 22, so that in the subsequent rotation process of the handle 29, the transmission screw 28 is coated with an oil layer, thereby avoiding the problem of rust on the surface of the transmission screw 28 due to long-term storage, and at the same time, it can prevent the transmission screw 28 from being placed in an internal part that is not easy to be coated with rust. When the valve adjustment is completed, the sealing ring 44 at the end of the sealing slide 42 is docked with the docking ring groove 45, so that the sealing ring cover 24 cooperates with the extrusion oil delivery pipe 43 to achieve a full sealing cover for the exposed parts of the functional screw shell 20 and the transmission screw 28, and the penetration ring pad 21 has a sealing effect on the transmission screw 28 after the oil seepage, thereby avoiding the problem of humid air entering through the threaded structure to cause rust.

The docking sealing ring 44 array is provided with a connecting port 47, and the connecting port 47 is connected to the extruded oil delivery pipe 43.

[0027] By pressing the turning handle 29 , the push function slip ring 41 slides in the oil-filled sliding cavity 38 , so that the oil in the oil-filled sliding cavity 38 is transferred through the extrusion oil delivery pipe 43 .

[0028] Preferably, the array of docking ring grooves 45 is provided with transmission grooves 46 , and the transmission grooves 46 are communicated with the corresponding communication ports 47 , and the ends of the transmission grooves 46 are communicated with the permeable hole rings 22 .

[0029] The oil in the oil-filled sliding cavity 38 is discharged through the connecting port 47 by squeezing, and is transferred through the transmission groove 46 so that the permeable hole ring 22 can output the anti-rust oil.

[0030] Preferably, a bolt fixing member 16 is installed between the valve cover 14 and the valve body 11 .

[0031] The valve cover 14 is fastened and installed by the bolt fixing member 16 to achieve a sealing effect.

[0032] Preferably, the functional screw housing 20 is installed with a pull rod 23 .

[0033] The pull rod 23 is convenient for hooking by fingers and then for pressing the handle 29 by palms to output the anti-rust oil to the transmission screw 28 .

[0034] Preferably, the rotating handle 29 is provided with a pushing slide 25 , and a pushing slide 27 is slidably installed up and down on the pushing slide 25 , and a return spring 26 is installed on the pushing slide 27 , and the driving screw 28 is fixedly installed on the pushing slide 27 .

[0035] The pushing slide plate 27 and the pushing slide groove 25 can only slide up and down but not rotate, so that the anti-rust oil output work can be pressed without affecting the effect of rotating and driving the transmission screw 28 to transmit the power.

[0036] Preferably, the valve body 11 is symmetrically provided with a fitting slide groove 33, and the fitting slide groove 33 is slidably installed with a fitting slide rod 34, and the fitting slide rod 34 is installed with a fitting spring 35, and the end of the fitting spring 35 is connected to the inner plate 31.

[0037] The transmission screw 28 drives the adapter block 36 to rise upward, thereby raising the valve plate 13. During the process, the fitting rubber pad 32 always fits the valve plate 13 to squeeze the liquid downward, and finally the convex structure of the fitting rubber pad 32 coincides with the concave structure of the valve plate 13, thereby achieving the effect of fitting the valve plate 13 to avoid moisture in the valve structure cavity 17.
