[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is provided in a steel or resin integral type or a vertically divided cover type used for piping for liquids, viscous bodies, or partially granulated bodies. The outer frame is mainly provided with a rhombus-shaped bending clamp and a pressure contact mechanism capable of sliding the horizontal clamp in a horizontal linear manner, and connecting flanges are assembled and arranged at both ends. A pinch valve equipped with a flexible pressure-resistant sleeve with a flange made of an elastic material and provided so as to be able to be cut off is provided, and a cylindrical socket of a predetermined length is provided in the face-to-face direction on the inner diameter of the connecting flange at both ends. The outer frame has both ends slidably fitted into a cylindrical shape, and a circumferential groove is provided at the inner end of the socket outer diameter portion to load a split ring. Provide a mating contact part on the taper Movable stoppers such as horizontal rotating members or screw rotating rings to fix both sides of the connecting flange at both ends in the axial direction of this external frame, taking measures such as providing biting on the split ring Are provided to form a valve. At this time, the intermediate body sleeve is provided with a pressure-resistant flange with reinforcement on the body having a predetermined elasticity, and the distance between the faces is molded according to the maximum length between the flanges at both ends of the outer frame. In addition, sanitary flanges or cam locks are provided with flanges on both ends of the connecting flange or on the discharge side, or adapters such as fitting spacers are attached integrally. The non-cleaning pinch valve is made of steel, which is prepared separately and is mainly made of a soft resin film. Is. Therefore, the non-cleaning type pinch valve formed in this way has the inter-surface distance extended before the pipe is assembled and is temporarily fixed by the movable stopper, and the pressure contact clamp is inserted. Close and temporarily extend the sleeve, extend the end of the adapter side, fold back the end of the adapter side, adjust the length of the liner, and then release the stopper between the fixed faces of the piping line The structure allows pipes to be attached and detached easily even at distances. The inner fluid is wetted with a liner, and after completion of the liquid passing work, it is disassembled from the mating connection flange, and the tip of the liner is returned and stretched while remaining liquid with a rubber band or the like. Because it is possible to stop leakage and remove the liner and eliminate the need for internal cleaning, a great merit in terms of workability and management can be expected. This valve is suitable for low-pressure use conditions, and when this valve is not cleaned alone, use an adapter on both end flange surfaces or a flange with a protruding tube, which will be described later. When used in various containers such as a small transport container, an adapter can be used only on the discharge side by using a liner integrally formed with the container. Of course, this pinch valve can be used without an adapter and a liner, and can also be used for multipurpose applications such as air-conditioning gas and slurry. The pressure-contacting clamp can be provided with a cross-sectional contact portion as described later in a male-female fitting manner to reliably shut off the fluid. The flange portion of the sleeve is desirably provided with reinforcement so as to prevent falling off during piping, and there is no problem even if the inner liner has a slack in the circumferential length and length. Note that the outer frame can be provided in a vertically divided assembly type, and the stopper can be provided in a screw type rotational type.
[0005]
In addition, the present invention provides an external frame in which the pressure contact mechanism is incorporated as described above, or is provided in a vertically assembled assembly type, and the both end connection mechanism is slidable in a cylindrical shape or a vertically semicircular assembled shape. In a pinch valve with a sleeve on the middle part, this clamp for pressure contact is provided with four sides of a rhombus with a slope in the right, left, top and bottom in the axial direction, or a horizontal part at the top. Are arranged in combination with a five-sided deformed diamond shape, etc., and a bending mechanism is formed by providing a hinge mechanism at each intersecting connecting portion, and the lower surface of the left and right lower inclined clamps on the left and right of the outer frame intermediate body As a structure capable of supporting a load by providing a sliding mechanism, the upper and lower clamps are formed in a horizontal cross section so that the sleeves can be pressed, and the contact cross sections of the upper and lower clamps are formed. Provided in a male waveform, the pressure contact part of the intermediate sleeve is locally pressed in a curved shape in the axial direction to ensure the blocking of the internal powder, and adapters are connected to both ends of the valve connection formed in this way. A non-cleaning pinch valve can be formed by detachably installing a wetted liner inside. As described above, the pinch valve of the present invention is made of steel and resin at the same time as the intermediate sleeve can be miniaturized because the clamp for pressure contact of the intermediate sleeve is provided in a rhombus or an irregular rhombus bend type. The structure is suitable for manufacturing, and is particularly suitable for providing dust-proof measures by being provided in the external cover system. Therefore, it is excellent in hygiene management and can be applied to each device and equipment. In addition, the clamp can also be provided with a horizontal portion at the bottom so that it has six sides, and at the same time, a pressure contact assisting means can be provided on the lower surface of the left and right lower clamps so that the pressure contact force effect can be further enhanced. .
[0006]
Further, the present invention is formed by providing a flange-type connection mechanism with sockets at both ends, and providing a non-reinforcing or low-reinforcing elastic large sleeve with a flange at the intermediate body of the pinch valve. Then, install a flexible tubular cut-out protector with pressure resistance on the outside of the sleeve so that both ends of this protector are housed inside the socket, and connecting flanges on both ends are connected to the piping. When the sleeve and the protector are fixed and pressed at the same time, the body of the sleeve fixed between the faces is extended so that both ends of the protector that slides following the sleeve stay in the socket. The barrel portion of the sleeve exposed from the socket can be formed so as to be able to receive pressure on the inner surface of the socket. The pressure-resistant protector-type pinch valve formed as described above can be reduced in size by greatly reducing the distance between the initial surfaces of the valve itself by increasing the stretchability of the sleeve during pressure contact.
[0007]
Further, the present invention provides a pinch valve provided with the pressure contact mechanism, which is divided into upper and lower parts or integrally provided with both ends of an external frame, mainly with a flange on a container connection side such as a container as an external part. Fixed to the frame, the other end discharge side is provided in an up-and-down semicircular assembly type or cylindrical shape, and is slidably fitted to this using a connection base such as a sanitary flange with a coupling type socket, and The outer periphery of this socket is provided with a circumferential groove and measures are taken to prevent it from falling off, such as loading with a split ring. When the intermediate sleeve is press-contacted by the press-contact mechanism, the other end is fixed on the connection flange side, the other end is cut off and fixed to the outside of the socket with a tightening band to form a valve. Since the sleeve is pressed in a state where the connection flange is fixed to the external frame, the cap is slid in the center direction at the end of the external frame on the discharge side, allowing the internal fluid to be disconnected. It is also possible to configure such that the wetted liner is inserted and folded back to and removed from the base, and can be connected to the other pipe using a coupling or the like. A joint type connection method such as a cam lock can also be used. In addition, the liner with a nozzle integral with a container can be inserted in the flange part on the container side. A cylindrical sleeve can also be mounted using a flange with a socket. Further, in the present invention, it is also possible to prevent a wound by loosely mounting a brottor outside the sleeve.
[0008]
Further, according to the present invention, in the pinch valve, the both ends connecting mechanism of the external frame provided with the pressure contact mechanism is assembled at both ends with a connecting base with a socket that is slidably fitted with a means for preventing the dropping. The sleeve is formed in the middle part so that both ends are separated and fixed to the outside of the socket with a tightening band, etc., and when the sleeve is pressed by the pressure contact mechanism, the connection caps at both ends slide simultaneously in the center direction to It is also possible to form a valve by providing the distances at the same time so that the liquid contact liner can be attached to and detached from the inside of the valve so that both ends can be folded back, and the other pipe can be connected using means such as coupling. A joint type connection joint can also be used.
[0009]
The present invention also provides a short projection tube that protrudes to the outside of the inner surface of the flange with a socket that is fixed to or slidable at both ends or one end of the connection mechanism of the external frame of the pinch valve. Insert a wetted cylindrical resin liner into this projection and then attach it externally and abut an O-ring or the like on the outer periphery. This projection is fitted and connected to the mating pipe to form a non-cleaning pinch valve. You can also

The pressure-resistant sleeve 5 made of an elastic material such as rubber is disposed and the flange 5a is fixedly mounted. The middle part of the body is pressed up by the lower clamps 6A and 6B so that the internal liquid can be blocked and opened. The socket 7 showing the provided structure and extending the inner diameter portions of the flanges 4A, 4B to a predetermined length in both sides is arranged, and both ends 2A of the frame are provided in a cylindrical shape on the outer peripheral portion so as to be slidably fitted. And the fitting part B The groove 7a is provided in the outer peripheral portion of the inner end of the rack 7 and the split ring 8 is loaded, and the light frame end of the outer frame end 2A is provided in the taper C so that the drop prevention means is provided. In addition, horizontal rotation stoppers 9 that come into contact with the flanges 4A and 4B are provided at both ends of the outer frame 2 so that the surfaces of the flanges 4A and 4B can be fixed and released. Further, the sleeve 5A is provided with the maximum length when the distance between the flanges 4A and 4B of the outer frame 2 is extended, and the body portion is provided with a reinforcing member 10 having a predetermined stretchability, and is molded and attached with the flange 5A. Furthermore, a flanged sanitary flange, an adapter 11 such as a cam lock, or a fitting spacer 28, etc., which will be described later, are attached to both ends of the connecting flanges 4A and 4B or the discharge side. In addition, mainly, a wet-welded soft cylindrical liner 12 that is cut off at both ends, such as a resin film of about 100 microns, is inserted and attached with the tip end turned outward, and a gasket 13 is provided at the end or outer periphery. The coupling 14 or the like can be connected to the mating pipe 15 and can be removed, so that the liquid contact with the valve is eliminated by the internal mounting of the liner 12. It constitutes a Kiyoshishiki pinch valve 1A. The pinch valve 1A formed in this way has a wetted liner 12 inserted inside with the movable stopper 9 extending and fixing the inter-surface distance before assembling the pipes.
