[0002] The flat gate valve is a sliding valve with parallel gates as the closing member. The closing member can be a single gate or a double gate with an opening mechanism in between.

If it is a double-disc flat gate valve, the opening mechanism between the two gates can supplement this pressing force. Flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to the driving mode.

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] according to Figure 1-5 As shown, this embodiment proposes a novel high-temperature resistant flat gate valve, comprising an inlet and outlet housing assembly 1 and an opening and closing component 3. A driving mechanism 2 connected by bolts is provided at the top of the inlet and outlet housing assembly 1, and an opening and closing component 3 is provided at the output end of the driving mechanism 2.

[0022] The opening and closing component 3 includes a threaded strip 301, a threaded hole plate 302, a limit expansion strip 303, a bolt valve plate 304, a spring rod group 305 and a gasket 306. The threaded strip 301 is arranged at the output end of the driving mechanism 2. The output end of the threaded strip 301 passes through the threaded hole plate 302 and is threadedly connected to the bolt valve plate 304. A limit expansion strip 303 is arranged above both ends of the threaded hole plate 302, and a spring rod group 305 is arranged at the bottom end of the bolt valve plate 304, and a gasket 306 is arranged at the bottom end of the spring rod group 305.

[0023] The threaded hole plate 302 , the bolt valve plate 304 and the gasket 306 are arranged parallel to each other, and the spring rod group 305 has a telescopic damping structure.

[0024] In this embodiment, when the threaded strip 301 is spirally operated, the threaded strip 301 is spirally operated, so that the threaded hole plate 302 and the bolt valve plate 304 are spirally operated, so that the bolt valve plate 304 cooperates with the limiting telescopic strip 303 and the spring rod group 305, so that the pores of the bolt valve plate 304 are opened with the valve shell compartment 103, the flange 104, and the inlet and outlet pipes 105 to achieve the effect of outputting materials.

[0025] The inlet and outlet shell assembly 1 includes a support column 101, a tray 102, a valve shell compartment 103, a flange 104, an inlet and outlet pipe port 105, a side strip 106, a light-shielding plate 107, an assembly plate 108, a porous base 109, a vacuum chamber 1010 and a mirror 1011. The tray 102 is provided on the top side of the support column 101, and the valve shell compartment 103 is provided on the top side of the tray 102. A flange 104 with bolts is provided on the lower side of the valve shell compartment 103, and the outer end of the flange 104 is provided with an inlet and outlet pipe port 105.

[0026] In this embodiment, when in use, the support column 101 is combined with the tray 102 to be placed at the processing site, and the valve shell cabin 103 is lifted after support to achieve the supporting effect, and the flange 104 is bolted together with the input end and the output end of the valve shell cabin 103, and the inlet and outlet pipes 105 are connected to the outer side of the flange 104 to achieve the connection effect.

[0027] A side strip 106 is provided on the upper side of the valve housing cabin 103, and a light-shielding plate 107 is provided at an angle at one end of the side strip 106. Assembly plates 108 assembled with bolts are provided at both ends of the valve housing cabin 103, and a porous base 109 is provided on the outer side of the assembly plate 108. A vacuum cabin 1010 is provided on the outer side of the porous base 109, and a mirror 1011 is provided on the outer side of the vacuum cabin 1010.

[0028] In this embodiment, since the vacuum chamber 1010 has a vacuum structure and the porous base 109 has a porous duct structure, and is combined with the light shielding plate 107 and the mirror 1011, the device can still operate normally in a high temperature environment, achieving a high temperature resistance effect.

[0029] The driving mechanism 2 includes a lower bolt cover 201, an upper bolt seat 202, a frame sleeve 203, a fin group 204, an upper shield plate 205, a sealing shaft seat 206, a gear box 207, a hand wheel 208, a driving motor 209 and a meshing gear group 2010. The lower bolt cover 201 is bolted to the top side of the valve housing compartment 103. The top of the lower bolt cover 201 is provided with an upper bolt seat 202 assembled with bolts, the top side of the upper bolt seat 202 is provided with a frame sleeve 203 assembled with bolts, the side of the frame sleeve 203 is provided with a fin group 204 assembled with bolts, and an upper shield plate 205 is provided above one end of the frame sleeve 203.

[0030] In this embodiment, since the lower bolt cover 201 is bolted onto the top side of the valve housing compartment 103, the lower bolt cover 201 is used in conjunction with the upper bolt seat 202 to bolt the frame 203 for installing the fin group 204 and the upper baffle 205, thereby achieving a splicing effect. The heat can be effectively dissipated quickly through the fin group 204 and the upper baffle 205, and the effect of shading and avoiding heat can be achieved.

[0031] A sealing shaft seat 206 is provided on the inner side of the frame sleeve 203, and a gear box 207 is provided on the top side of the sealing shaft seat 206. A hand wheel 208 is provided above the gear box 207. A driving motor 209 is provided at one end of the gear box 207, and an engaging gear set 2010 is provided at the output end of the driving motor 209.

[0032] In this embodiment, when opening and closing operations are required, the drive motor 209 is started to output power to drive the output end to operate, or in a defective situation, the hand-cranked wheel 208 is used to output power. After the power is output, the meshing gear set 2010 inside the gear box 207 is meshed and driven to operate, and when the meshing gear set 2010 is running, the threaded bar 301 is operated.

[0033] The working principle of this new high-temperature resistant flat gate valve is as follows: when in use, the support column 101 is matched with the upper tray 102 to be placed at the processing site, and the valve housing compartment 103 is lifted up after being supported to achieve the supporting effect, and the flange 104 of the input end and the output end of the valve housing compartment 103 are bolted together, and the inlet and outlet pipes 105 are connected to the outer side of the flange 104 to achieve the communication effect. Since the lower bolt cover 201 is bolted on the top side of the valve housing compartment 103, the lower bolt cover 201 is used to match the upper bolt seat 202 to bolt the frame 203 for installing the fin group 204 and the upper baffle 205, so as to achieve the splicing effect. The fin group 204 and the upper baffle 205 can effectively dissipate heat quickly and achieve the effect of shading and avoiding heat. When opening and closing operations are required, the drive motor 209 is started to output power to drive the output end to operate, or a manual operation is used in the case of defects. The rocker 208 outputs power. After the power is output, the meshing gear set 2010 inside the gear box 207 is engaged and driven. When the meshing gear set 2010 is running, the threaded bar 301 is running. When the threaded bar 301 is spirally running, the threaded bar 301 is spirally running. After the spiral running of the threaded bar 301, the threaded hole plate 302 and the bolt valve plate 304 are spirally running, so that the bolt valve plate 304 cooperates with the limit telescopic bar 303 and the spring rod group 305, so that the pores of the bolt valve plate 304 are opened with the valve housing chamber 103, the flange 104, and the inlet and outlet pipes 105 to achieve the effect of outputting materials. Since the vacuum chamber 1010 has a vacuum structure and the porous base 109 has a porous duct structure, and is combined with the light shielding plate 107 and the mirror 1011, the equipment can still operate normally in a high temperature environment, achieving a high temperature resistance effect.
