Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a cast steel gate valve with a stable structure. Background Technology

[0002] A gate valve is a valve in which the closing element (gate) moves vertically along the centerline of the passage. Gate valves can only be used for fully opening and fully closing shut-off in pipelines; they cannot be used for regulation or throttling. Gate valves are a widely applicable type of valve, generally used for shut-off devices with a diameter DN≥50mm. Sometimes, gate valves are also used for shut-off devices with very small diameters. When using existing cast steel gate valves, impurities are filtered through the filter screen, requiring regular cleaning by staff, which affects the overall use of the gate valve. Furthermore, impurities repeatedly come into contact with the valve seat and valve disc, causing friction between them, which affects the sealing stability of the valve seat and valve disc and thus the overall lifespan of the gate valve. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cast steel gate valve with a stable structure, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes a stabilizing structure 1, which includes an inlet pipe 11. A stabilizing support assembly 12 is fixed on the inlet pipe 11. The stabilizing support assembly 12 includes a first fixing plate 121. A rotating rod 122 is fixed between the first fixing plates 121. A rotating ring 123 is rotatably connected to the rotating rod 122. A first support plate 124 is fixed on the rotating ring 123. A sliding plate 125 is slidably connected to the first support plate 124. A base 126 is fixed to the lower side of the sliding plate 125.

[0024] Among them, there are three sets of stabilizing support components 12, and the three sets of stabilizing support components 12 are symmetrically arranged;

[0025] Specifically, the first support plate 124 has multiple sets of threaded holes, which are evenly distributed on the first support plate 124. The sliding plate 125 has a sliding groove, and the first support plate 124 is slidably connected in the sliding groove. The first support plate 124 and the sliding plate 125 are fixed by bolts.

[0026] In the above scheme, the user pulls the sliding plate 125, and the first support plate 124 moves out from the sliding plate 125 to the required length. The first support plate 124 and the sliding plate 125 are fixed by bolts. The sliding plate 125 is rotated, and the rotating ring 123 on the rotating rod 122 between the first fixed plate 121 adjusts the position of the base 126. The base 126 is fixed to the ground by bolts, thereby providing limit support for the entire device and improving the stability of the entire gate valve.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the stable structure 1 is connected to the filter structure 2. The filter structure 2 includes a filter tube 25. A filter screen 21 is detachably installed on the filter tube 25. A cleaning component 22 is embedded in the filter screen 21. The filter tube 25 is connected to the spray component 23 and the drainage component 24. The cleaning component 22 includes a motor box 221. The motor in the motor box 221 drives the cleaning brush 223 on the second support plate 222 to rotate. The spray component 23 includes a first water inlet pipe 231. The first water inlet pipe 231 is connected to the nozzle 234 through a second water inlet pipe 232. A pressure pump 233 is fixed on the second water inlet pipe 232. The drainage component 24 includes a discharge pipe 241. An electric valve 242 is fixed in the discharge pipe 241. The discharge pipe 241 is connected to the drain pipe 243.

[0028] Among them, there are two sets of filter screens 21 with different mesh densities. The motor in the motor box 221 is a double-headed motor. There are two sets of second support plates 222. Each set of second support plates 222 has a slider fixed on it. The slider is slidably connected in the groove opened on the filter screen 21, thereby ensuring that the cleaning brush 223 fits the surface of the filter screen 21.

[0029] Specifically, there are two sets of nozzles 234, which are symmetrically arranged and located on both sides of the filter screen 21.

[0030] Furthermore, the drainage assembly 24 is provided in three sets, with the three sets of drainage assemblies 24 located on both sides of the filter screen 21;

[0031] In the above scheme, the fluid is filtered with the assistance of the filter screen 21. The filter screen 21 is fixed on the first water inlet pipe 231. When it is necessary to treat impurities, the valve disc 33 on the valve seat 32 is sealed, and the electric valve 242 in the first water inlet pipe 231 is opened. With the assistance of the pressure pump 233 on the second water inlet pipe 232, the filtered fluid enters the nozzle 234 through the first water inlet pipe 231 and the second water inlet pipe 232. With the assistance of multiple nozzles 234, the surface of the filter screen 21 is rinsed. With the assistance of the double-head motor in the motor box 221, the cleaning brush 223 on the second support plate 222 is rotated to clean the surface of the filter screen 21. The electric valve 242 in the discharge pipe 241 is opened, and impurities and wastewater are discharged through the drain pipe 243 and the filter pipe 25.

[0032] like Figure 1 and Figure 2 As shown, the filter structure 2 is connected to the gate valve assembly 3. The gate valve assembly 3 includes a valve body 31, a valve seat 32 is embedded in the valve body 31, a valve disc 33 is embedded in the valve seat 32, a top cover 34 is detached and installed on the upper side of the valve body 31, a screw 35 passes through the top cover 34, a handle 36 is fixed on the upper side of the screw 35, and a valve disc 33 is fixed on the lower side of the screw 35.

[0033] A sealing ring is provided between the valve body 31 and the top cover 34, which improves the sealing effect of the gate valve.

[0034] Specifically, two sets of stabilizing support components 12 are fixed on the valve body 31, and the two sets of stabilizing support components 12 are symmetrically arranged about the central axis of the valve body 31;

[0035] In the above scheme, rotating the handle 36 causes the screw 35 on the top cover 34 to rotate, and the rotation of the screw 35 causes the valve disc 33 to separate from the valve seat 32 on the valve body 31, thereby ensuring normal fluid delivery.

[0036] Working principle: When using this cast steel gate valve with a stable structure, the external power supply is turned on, the stability of the gate valve is improved by the setting of the stabilizing structure 1, the fluid is filtered by the setting of the filtering structure 2, and the fluid is blocked or opened by the setting of the gate valve assembly 3.
