Description

Technical Field

[0029] A valve is a device used to control the direction, pressure, and flow rate of a fluid in a fluid system. It is a device that enables the medium (liquid, gas, powder) in a piping and equipment to flow or stop and can control its flow rate. The buffer structure provided by this device makes the valve body of this valve not easily damaged by high-speed water flow to the valve block 202 during the use in a high-flow-rate water pipeline, and has a good protection effect.

[0030] Such as Figures 1-6As shown, the present invention provides a technical solution: a valve body and a valve using the valve body, comprising a valve body transverse tube 1, a valve body vertical tube 101 is connected to the middle part of the valve body transverse tube 1, a valve cover is arranged on the top of the valve body vertical tube 101, a control structure is arranged in the valve body vertical tube 101, a buffer structure is symmetrically arranged in the valve body transverse tube 1, and the buffer structure comprises fixed hollow column blocks 4 symmetrically fixed at both ends of the valve body transverse tube 1, the fixed hollow column blocks 4 are adapted to the inner wall of the valve body transverse tube 1, a through hole with a rectangular cross section is opened in the fixed hollow column block 4, a plurality of rotating rods 401 are evenly and vertically inserted in the through hole, and buffer plates 402 adapted to the through hole are fixed on the rotating rods 401, and the buffer plates 402 are evenly spaced. The distances are staggered up and down, the top of the rotating rod 401 passes through the fixed hollow column block 4 and the valve body cross tube 1, the top of the rotating rod 401 is fixed with a rotating sprocket 403, the outer side of the rotating sprocket 403 is connected with a chain 404 for transmission, the top of the rotating rod 401 on one side is connected with a motor, the buffer structure also includes an arch plate 405 fixed on the top of the valve body cross tube 1, the rotating rod 401 passes through and is inserted on the arch plate 405, the motor is fixed to the arch plate 405, and an installation box 409 fixed to the valve body cross tube 1 is arranged on the outside of the arch plate 405, the installation box 409 includes a top cover and an installation box 409 shell, the top cover and the installation box 409 shell are installed by bolts, which is easy to install and maintain.

[0031] It should be noted that the rotating rod 401 is rotatably connected with the fixed hollow column block 4 and the valve body cross tube 1, and a sealing member 410 is arranged between the rotating rod 401 and the fixed hollow column block 4 and the valve body cross tube 1. A reinforcing rod fixed to the buffer plate 402 is symmetrically fixed on the rotating rod 401. A flow rate sensor 406 is installed at the outflow end of the fixed hollow column block 4. A first stop rod 407 and a second stop rod 408 adapted to the buffer plate 402 are arranged at the bottom end of the fixed hollow column block 4. Through the setting of the buffer structure, when the valve body valve needs to be used to close at a high flow rate, the motor is started, and the motor drives its connection The rotating rod 401 rotates, and the sprocket on the rotating rod 401 drives the chain 404 to rotate, so that the chain 404 drives all the rotating rods 401 to rotate, so that the buffer plate 402 rotates from the second stop rod 408 position to the first stop rod 407 position, that is, the buffer plate 402 rotates from the inclined position to the position perpendicular to the water flow, thereby blocking and buffering the water flow. At the same time, the cylinder 205 drives the valve stem 201 and the valve block 202 to descend and complete the closing, so that the impact force of the water flow on the valve block 202 in the valve body is weakened, and it is not easy to cause the valve block 202 inside the valve body to be damaged, thereby better ensuring the use effect of the valve body.

[0032] It should be noted that the control structure includes a fixed block 2 fixed in the vertical pipe 101 of the valve body. A valve rod 201 is inserted through the middle of the fixed block 2. A fixed disk 203 is fixed at the top end of the valve rod 201. A cylinder 205 is installed between the fixed disk 203 and the valve cover. A valve block 202 adapted to the horizontal pipe 1 and the vertical pipe 101 of the valve body is fixed at the bottom of the valve rod 201. The fixed disk 203 and the valve rod 201 are integrated. A plurality of limit blocks 204 are evenly fixed on the outer circumference of the outer wall of the fixed disk 203. A limit groove adapted to the limit block 204 is provided on the inner wall of the vertical pipe 101 of the valve body. It should be noted that the cylinder 205 drives the fixed disk 203, the valve rod 201 and the valve block 202 to move up and down, so as to control the opening and closing of the pipeline.

[0033] It should be noted that a sealing structure is provided between the fixed block 2 and the valve rod 201 and between the vertical pipe 101 of the valve body and the valve block 202. The sealing structure includes mounting grooves opened on the inner walls of the fixed block 2 and the vertical pipe 101 of the valve body. A lip seal ring 3 adapted to each other is installed in the mounting groove. The sealing structure also includes a plurality of L-shaped support soft rods 306 symmetrically arranged on the inner circumference of the lip seal ring 3. The lip seal ring 3 includes a first side lip, a second side lip and a connecting ring. The lip seal ring 3 is arranged with the opening facing downwards. A plurality of first mounting blocks 301 are evenly installed on the inner side surface of the first side lip. A fixed rod 302 is fixed in the middle of one side surface of the first mounting block 301. A plurality of second mounting blocks 303 corresponding to the first mounting blocks 301 are evenly installed on the inner side surface of the second side lip towards the inside. A fixed pipe 304 adapted to the fixed rod 302 and slidably connected thereto is fixed in the middle of one side surface of the second mounting block 303. A spring 305 is arranged in the fixed pipe 304. After the spring 305 is subjected to an external force, it is compressed and contracted. At this time, the spring 305 has a reaction force, so that the spring 305 has an extrusion and support effect on the first side lip and the second side lip, avoiding the phenomenon of leakage due to gaps in the valve body.

[0034] It should be noted that both ends of the spring 305 are respectively connected to the end of the fixed rod 302 and the second mounting block 303. A first groove adapted to the first mounting block 301 is opened in the first side lip, and a second groove adapted to the second mounting block 303 is opened in the second side lip. Through the setting of the sealing structure, when the internal high pressure is generated in the valve body under high-speed water flow, there is a certain extrusion effect on the lip seal ring 3, while the L-shaped support block, the first mounting block 301 and the second mounting block 303 play a supporting role for the lip seal ring 3. At the same time, after the spring 305 is compressed, it generates a reaction force, making the sealing performance between the lip seal ring 3 and the valve rod 201 and the valve block 202 better.

[0035] A valve applying this valve body includes a valve body. Installation flanges are provided at both ends of the horizontal pipe 1 of the valve body and at the top end of the vertical pipe 101 of the valve body. The installation flanges facilitate the installation and fixation of this valve body valve for use.

[0036] Working principle: The valve body of this valve is installed between the water flow pipelines through the installation flange, which is convenient for controlling the water flow in the pipeline. Under normal flow conditions, the buffer plate 402 contacts the second stop lever 408. At this time, the buffer plate 402 is inclined with the water flow in the horizontal pipe 1 of the valve body, which is convenient for the water flow to pass smoothly. At the same time, the flow velocity sensor 406 monitors the water flow velocity. If it is necessary to close this pipeline, first, the motor drives the rotating rod 401, the rotating sprocket 403 and the chain 404 to rotate, so that all the rotating rods 401 and the buffer plate 402 rotate slowly until the buffer plate 402 contacts the first stop lever 407, and the buffer plate 402 rotates to a direction perpendicular to the water flow direction in the pipeline. At this time, the buffer plate 402 has a certain blocking effect on the water body, reducing the water flow velocity, so that the valve block 202 is not easily damaged. At the same time, the cylinder 205 is started, so that the cylinder 205 drives the fixed disk 203, the valve stem 201 and the valve block 202 to descend as a whole until the pipeline is closed. At this time, the limit block 204 slides in the limit groove to play a limiting role. It should be noted that the above horizontal pipe 1 of the valve body, the vertical pipe 101 of the valve body, the valve stem 201, the cylinder 205, the lip seal 3, the flow velocity sensor 406, the valve block 202, the chain 404, and the rotating sprocket 403 are prior arts, so the working principle thereof will not be explained in detail herein.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
