[0002] Valves are control components in fluid delivery systems, with functions such as cutoff, regulation, backflow, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest stop valves to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media.

[0003] During the use of the valve, in order to ensure the sealing effect of the connection between the valve and the connecting pipe, it is often necessary to place a sealing gasket between the valve and the connecting pipe for sealing, and the installation position and angle of the valve will be set according to the connecting pipe. In actual use, the sealing gasket is mostly placed directly between the connecting pipe and the valve, resulting in that when the end face of the valve connecting plate is perpendicular to the horizontal plane, it is necessary to fix the connecting pipe and the valve connecting plate while the installer needs to maintain the position of the sealing gasket, thereby increasing the difficulty of valve installation. For this purpose, a valve sealing device is proposed. Utility Model Content

[0029] As Figures 1 to 7 shown, a valve sealing device includes: a body 1, a plurality of communicating pipes 101 are provided outside the body 1, and the communicating pipes 101 are communicated with the body 1; a connecting mechanism is provided outside the communicating pipes 101 for connecting the connecting pipe and the communicating pipes 101. The sealing mechanism includes a connecting member 2, a sealing member 3 and a first support member 4. The connecting member 2 is provided outside the communicating pipes 101, the sealing member 3 is provided inside the connecting member 2, and the connecting member 2 cooperates with the sealing member 3 to seal the gap between the connecting pipe and the communicating pipes 101. The first support member 4 is provided inside the sealing member 3, and the first support member 4 is used to provide support for the sealing member 3. Specifically, during use, first, the connecting pipe and the body 1 are installed through the sealing member 3 to ensure that the body 1 can control the flow of the medium inside the connecting pipe. While connecting the connecting pipe, the gap between the connecting pipe and the body 1 is sealed through the cooperation of the sealing member 3 and the first support member 4 to prevent the medium inside the connecting pipe from leaking through the gap during use. A control valve is provided inside the body 1, so that during use, the control valve cooperates with the body 1 to control the on-off of the medium inside the connecting pipe. The body 1 is a prior art and will not be explained in detail here.

[0030] As Figures 1 to 7 shown, the connecting member 2 includes a plurality of first connection disks 201. The first connection disks 201 are connected to the communicating pipes 101. A second connection disk 202 is provided at one end of the first connection disk 201. A plurality of bolts are provided inside the first connection disk 201 and the second connection disk 202. Specifically, the first connection disk 201 and the second connection disk 202 are respectively connected to the communicating pipes 101 and the connecting pipe, so that during use, the medium inside the connecting pipe can be introduced into the body 1. The first connection disk 201 and the communicating pipes 101 can be integrally formed or welded. Through the cooperation of the bolts, the first connection disk 201 and the second connection disk 202, the communicating pipes 101 and the connecting pipe are communicated during use.

[0031] As Figures 1 to 7As shown, the seal 3 includes a plurality of mounting rings 301. The plurality of mounting rings 301 correspond to the first connection disk 201 one by one, and the mounting rings 301 are arranged between the first connection disk 201 and the second connection disk 202. A first sealing ring 303 and a second sealing ring 304 are respectively provided on the inner and outer walls of the mounting ring 301. Sealing grooves 306 are provided on the contact surfaces of the first sealing ring 303, the second sealing ring 304, the first connection disk 201, and the second connection disk 202. Specifically, during the connection process of the first connection disk 201 and the second connection disk 202, the mounting ring 301, the limiting member 302, and the second sealing ring 304 are placed between the first connection disk 201 and the second connection disk 202, so as to seal the gap between the first connection disk 201 and the second connection disk 202, avoiding the existence of a gap after the first connection disk 201 and the second connection disk 202 are connected, and thus preventing the leakage of the medium. A convex platform is provided on the side of the first connection disk 201 relative to the second connection disk 202. The outer diameter of the mounting ring 301 is the same as the inner diameter of the mounting ring 301, so as to provide position positioning during the placement of the mounting ring 301, avoiding the position staggered of the first sealing ring 303 and the second sealing ring 304 relative to the first connection disk 201 and the second connection disk 202 during use, and ensuring the sealing effect of the second sealing ring 304 and the first sealing ring 303 during use. Both the second sealing ring 304 and the first sealing ring 303 are made of rubber material, and can be extruded during the connection process of the first connection disk 201 and the second connection disk 202, so that they can be closely attached to the first connection disk 201 and the second connection disk 202 during the sealing process. The sealing grooves 306 can separate the contact surfaces of the mounting ring 301, the first sealing ring 303, the first connection disk 201, and the second connection disk 202, thereby improving the sealing effect of the mounting ring 301 and the first sealing ring 303. The number of the sealing grooves 306 is selected according to the actual use requirements.

[0032] As Figures 1 to 7As shown, a cavity 305 is further formed inside the mounting ring 301. A first support member 4 and a second support member 5 are respectively disposed inside the cavity 305. Specifically, when in use, the first support member 4 and the second support member 5 can provide a supporting force along the height direction of the mounting ring 301, so that the mounting ring 301 can be closely attached to the first connection disk 201 and the second connection disk 202. Before the installation of the second support member 5 and the first support member 4, the first support member 4 and the second support member 5 can pre-provide a supporting force to the mounting ring 301 to prevent the mounting ring 301 from collapsing inward. When the first connection disk 201 and the second connection disk 202 clamp the mounting ring 301, since the second support member 5 and the first support member 4 are compressed during the clamping process of the first connection disk 201 and the second connection disk 202, the second support member 5 and the first support member 4 provide support to the mounting ring 301, further ensuring that the mounting ring 301 is closely attached to the first connection disk 201 and the second connection disk 202, and preventing the medium from leaking through the gap between the first connection disk 201, the second connection disk 202 and the mounting ring 301 during use.

[0033] As Figures 1 to 7 shown, the first support member 4 includes a support pad 402. The support pad 402 is disposed inside the cavity 305. Fixing rings 401 are provided at both ends of the support pad 402, and the fixing rings 401 are in contact with the sealing groove 306. Support rings 403 are provided on one side of the opposite surfaces of the fixing rings 401. The support rings 403 are connected to the support pad 402. Specifically, both the support pad 402 and the second support member 5 are made of elastic materials. The support pad 402 provides support and guidance for the moving direction of the support rings 403 to ensure the accuracy of the supporting direction of the support rings 403 to the mounting ring 301 during use. The fixing rings 401 connect the plurality of support rings 403, so that the supporting force of the support rings 403 can be evenly applied to the mounting ring 301 through the fixing rings 401, ensuring that the mounting ring 301 can be closely attached to the first connection disk 201 and the second connection disk 202 during use.

[0034] As Figures 1 to 7As shown, a plurality of slots 203 and limiting grooves 204 are further formed on the side of the first connection disk 201 relative to the mounting ring 301, and the slots 203 communicate with the limiting grooves 204. Limiting members 302 are provided inside the limiting grooves 204, and the limiting members 302 are adapted to the limiting grooves 204 and are connected to the mounting ring 301. Specifically, the fact that the limiting members 302 are adapted to the limiting grooves 204 means that while the limiting members 302 can be inserted into the limiting grooves 204, the first connection disk 201 and the mounting ring 301 are connected through the cooperation of the support pads 402 and the limiting grooves 204, preventing the mounting ring 301 from moving relative to the first connection disk 201 during the placement process. The shape of the limiting grooves 204 can be in the shape of a T-shaped arc groove or a dovetail-shaped arc groove, and the shape of the limiting members 302 can be in the shape of a T-shaped arc, a dovetail-shaped arc, a T-shaped block or a dovetail-shaped block. During use, through the cooperation of the limiting members 302 and the limiting grooves 204, the position of the mounting ring 301 relative to the first connection disk 201 can be fixed while the mounting ring 301 and the first connection disk 201 are pre-installed, preventing the mounting ring 301 from moving relative to the first connection disk 201 when the first connection disk 201 is placed vertically, ensuring the sealing effect after the connection of the first connection disk 201 and the second connection disk 202. The vertical direction means that the end face of the first connection disk 201 is perpendicular to the horizontal plane. The limiting members 302 do not contact the bottom surface of the slots 203 during installation, avoiding the existence of a gap between the mounting ring 301 and the first connection disk 201 due to the contact between the limiting members 302 and the bottom surface of the slots 203 during use.
