Description

Technical Field

[0001] This utility model relates to the field of flat gate valve technology, specifically a flat gate valve with a double sealing structure. Background Technology

[0002] A flat gate valve is a sliding valve with a parallel gate as its closing element. Existing flat gate valves, such as those disclosed in CN213117659U, feature a nickel-based alloy layer that provides excellent corrosion and oxidation resistance, while a hot-dip galvanized layer offers aesthetic appeal and rust prevention, protecting the entire surface and providing good impact and wear resistance. The hot-dip galvanized and nickel-based alloy layers enhance overall corrosion resistance, and the epoxy resin coating effectively improves corrosion resistance, alkali resistance, and high-temperature resistance. A nano-waterproof coating offers multiple benefits including waterproofing, high-temperature resistance, crack resistance, seepage prevention, freeze protection, impact and abrasion resistance, and corrosion resistance. However, some problems remain, such as poor sealing performance, which affects the valve's service life. Furthermore, existing flat gate valves require bricks or support frames for outdoor use, which can easily scratch the valve surface during installation, causing unnecessary damage.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a flat gate valve with a double-sealing structure, such as... Figure 1 and Figure 2 As shown, the device includes a flat gate valve structure 1, which includes a gate valve housing 11. A first sealing component 12 and a second sealing component 13 are embedded in the gate valve housing 11. A position adjustment component 14 is fixed on the upper side of the second sealing component 13 and the first sealing component 12. A top cover 15 is fixed on the lower side of the position adjustment component 14. The top cover 15 is detachable and installable from the gate valve housing 11. The first sealing component 12 includes a valve body 121. A valve disc 122 is engaged and connected inside the valve body 121. A valve stem 123 is fixed on the upper side of the valve disc 122. The position adjustment component 14 includes a storage box 141. The storage box 141 adjusts the position of the sliding plate 143 by telescopic structure. The sliding plate 143 is located inside the hollow tube 142. A waterproof plate 144 is fixed on the upper side of the storage box 141.

[0022] In this application, the telescopic structure is a hydraulic cylinder, which is the prior art. The first sealing component 12 and the second sealing component 13 have the same structure, and both the first sealing component 12 and the second sealing component 13 are connected to the conveying pipe.

[0023] Furthermore, a groove is provided inside the hollow tube 142, and a sliding plate 143 is slidably connected inside the groove;

[0024] Specifically, the flat gate valve is equipped with anti-corrosion, anti-oxidation, waterproof coating, high temperature and crack resistance, and anti-seepage layer, which extends the service life of the entire flat gate valve.

[0025] In the above scheme, with the assistance of the hydraulic cylinder in the storage tank 141, the sliding plate 143 in the hollow tube 142 is moved downward by the hydraulic rod, thereby moving the valve stem 123 downward. The downward movement of the valve stem 123 causes the valve disc 122 to seal the valve body 121 inside the gate valve housing 11. Similarly, the second sealing component 13 is sealed, achieving a double-layer sealing effect. The waterproof plate 144 serves to provide waterproofing and sunshade. The operator removes the bolts 343 on the top cover 15, separating the top cover 15 from the gate valve housing 11, thus facilitating maintenance of the inside of the gate valve housing 11.

[0026] like Figure 1 and Figure 2 As shown, the flat gate valve structure 1 is disassembled and installed with energy-saving component 2 and auxiliary support structure 3. Energy-saving component 2 includes base 21, with connecting rod 22 fixed on base 21. Photovoltaic panel 23 is disassembled and installed on connecting rod 22. Photovoltaic panel 23 is electrically connected to battery 24 through transmission line.

[0027] The base 21 is detached and installed from the storage box 141 by bolts 343;

[0028] In the above scheme, the base 21 is attached to the storage box 141, and the bolt 343 passes through the base 21 and the storage box 141 to fix the base 21. The photovoltaic panel 23 on the connecting rod 22 converts solar energy into electrical energy, stores it in the battery 24, and provides electrical energy for the entire device, thereby saving electrical energy.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary support structure 3 is located below the energy-saving component 2. The auxiliary support structure 3 includes a screw 31. A limit protrusion 32 is fixed at one end of the screw 31 away from the gate valve housing 11. A limit nut 33 and a support component 34 pass through the screw 31. The support component 34 is located on one side of the limit nut 33. The support component 34 includes a support rod 341. A sliding rod 342 is slidably connected to the support rod 341. The sliding rod 342 and the support rod 341 are limited and fixed by bolts 343.

[0030] Among them, the auxiliary support structure 3 is provided in two sets, and the two sets of auxiliary support structures 3 are symmetrically arranged about the central axis of the gate valve housing 11;

[0031] Specifically, there are two sets of support components 34, and the two sets of support components 34 are symmetrically arranged about the central axis of the screw 31;

[0032] Furthermore, the support rod 341 has multiple sets of threaded holes, which are evenly distributed on the sliding rod 342. A rubber anti-slip pad is fixed on the lower side of the sliding rod 342, thereby playing the role of anti-slip and buffering.

[0033] In the above scheme, the sliding rod 342 is rotated to the desired position, and then pulled. The sliding rod 342 and the support rod 341 slide to the desired length. The bolt 343 is then inserted through the support rod 341 and the sliding rod 342. The bolt 343 is rotated to fix the support rod 341 and the sliding rod 342. The limiting nut 33 on the screw 31 is rotated to limit and fix the two sets of support rods 341. The bolt 343 is then inserted through the lower side of the sliding rod 342 to limit and fix the sliding rod 342.

[0034] Working principle: When using this flat gate valve with a double sealing structure, the external power supply is connected. The sealing effect of the flat gate valve is ensured by the setting of the flat gate valve structure 1, the energy-saving component 2 plays an energy-saving role, and the auxiliary support structure 3 plays a supporting role.
