[0019] The bidirectional valve seat 102 includes framework 106 and external rubber lining 107, the framework 106 has groove 108, and the external rubber lining 107 is placed in the groove 108.

[0020] For this specific embodiment, in specific use, by the electric drive device 103 as power, remote control can be realized, and the gate opening and closing can also be controlled by directly opening the electric drive device 103 on site, when the electric drive device 103 controls the gate 105 to be opened, the valve body 101 installed with the bidirectional valve seat 102 prevents the medium from overflowing outward, when the electric drive device 103 controls the gate 105 to be closed, the bidirectional valve seat 102 prevents the medium from overflowing inward, and the gate 105 prevents the medium from flowing in at the valve outlet end, the bidirectional valve seat 102 can be directly replaced when it is worn, without replacing the entire electric double sealing gapless valve, the sealing assembly is installed to improve the sealing performance of the gate during opening and closing, so that the technical problems of the prior art, such as inconvenient equipment maintenance, short service life of the valve, high operation difficulty and low convenience, are solved.

[0021] The sealing surface in the channel of the bidirectional valve seat 102 is made of rubber material and is shaped by special mold vulcanization. The sealing form is linear sealing. Under the pressure of the gate 105, the sealing surface is slightly deformed, the sealing line is widened, and the sealing effect is more reliable.

[0022] The sealing assembly includes rectangular ring 109, packing 110 and pressing plate 111, the rectangular ring 109 is arranged on the valve body 101, and the pressing plate 111 presses the packing 110 on the rectangular ring 109.

[0023] For this specific embodiment, by setting the rectangular ring 109 at the cavity on the passage in the valve body 101, the medium leakage can be effectively prevented, and by setting the packing 110 and using the pressing plate 111 to compress, the sealing performance can be enhanced.

[0024] Secondly, the mounting member includes a bracket 112 and a plurality of bolts 113, the bracket 112 is fixedly connected with the valve body 101, and the plurality of bolts 113 penetrates through the bracket 112 and is threadedly connected with the electric drive device 103.

[0025] For this specific embodiment, the electric drive device 103 is mounted on the bracket 112 through the plurality of bolts 113, and the connection with the valve body 101 is realized through the bracket 112.

[0026] Meanwhile, the lower end of the gate plate 105 is in a wedge type structure.

[0027] For this specific embodiment, by setting the lower end of the gate plate 105 in a wedge type structure, the gate plate 105 is sealed with the bidirectional valve seat 102 without damaging the valve seat, the bidirectional valve seat 102 is squeezed to widen the sealing line and increase the sealing when the valve is closed, and the wedge type structure enables the gate plate 105 to cut slag during the opening and closing process, thereby increasing the sealing performance.

[0028] In addition, the electric double-sealing gapless valve further includes a slag discharging device 114, which is fixedly connected with the valve body 101 and located at the lower end of the valve body 101.

[0030] The electric double-seal gapless valve of this utility model, in practical use, can be remotely controlled by the electric drive device 103, or the gate can be opened and closed directly by activating the electric drive device 103 on site. When the electric drive device 103 controls the gate 105 to be open, the medium enters the valve inlet end, and the valve body 101 with the bidirectional valve seat 102 installed prevents the medium from overflowing to the outside. When the electric drive device 103 controls the gate 105 to be closed, the bidirectional valve seat 102 prevents the medium from overflowing to the inside. The gate 105 prevents the medium from flowing in at the valve outlet end. When the bidirectional valve seat 102 is worn, it can be directly replaced without replacing the entire electric double-seal gapless valve. The installed sealing components improve the sealing performance of the gate during the opening and closing process. This solves the technical problems of existing electric double-seal gapless valves, such as inconvenience in equipment maintenance, short valve service life, high operation difficulty, and low convenience.

[0033] 2. The slag discharge device 114 can discharge the residual slag and liquid in the valve body 101, improving the efficiency of the gate 105, reducing the wear of the valve body 101, and extending its service life. It can be used in pipelines for conveying fine particulate materials such as slurry and sewage in industries such as mining, metallurgy, power plants, coal, and chemicals with a nominal diameter of 1200mm or less.

[0034] 3. The bidirectional valve seat 102 has a built-in unique reinforcing skeleton 106, which can greatly increase the strength of the bidirectional valve seat 102 and enable the equipment to operate stably under harsh working conditions.

[0035] 4. The upper end of the valve body 101 and the rectangular ring 109 of this utility model have a sealing groove in the middle cavity. During the opening and closing process, the gate plate 105 and the rectangular ring 109 form an upper seal to prevent the medium from leaking upward.

[0036] 5.
