Embodiment 1

[0019] see Figure 1-2 , the present invention provides a two-way pipeline sealing device, comprising two discs 1, concave blocks 4 and limit blocks 5, two discs 1 are provided with threaded holes 12 penetrating through the end faces of both sides, two A connecting block 2 is fixedly installed on the circumferential surface of the disk 1, and a slider 3 is fixedly installed on the tops of the two connecting blocks 2, and the two sliders 3 are all slidably installed in the groove of the concave block 4. The top of the slide block 3 is hinged with drive rods 7, and the sides away from the concave block 4 on the two drive rods 7 are all hinged at the bottom of the limit block 5, and the limit block 5 is located above the concave block 4, and the concave The shaped block 4 is provided with openings for the movement of the two driving rods 7 , and the concave block 4 is provided with a limiting mechanism for fixing the position of the limiting block 5 .

[0020] In this embodiment...

Embodiment 2

[0025] see Figure 1-2 , this embodiment is further optimized on the basis of Embodiment 1, specifically, the limit mechanism includes a fixed plate 8 symmetrically arranged on the top of the concave block 4 and located on both sides of the limit block 5, two fixed plates 8 are provided with sockets, and the limit mechanism also includes screws 6 that are compatible with the sockets. The inside of the sockets is provided with threads that are compatible with the screws 6. The limit mechanism includes through holes that are opened on the limit block 5. The screws 6 pass through the through holes and are threadedly connected with the two fixing plates 8 respectively.

[0026] By using the screw 6 to pass through the limit block 5, and threadedly connected with the two fixing plates 8, and at the same time hinge the driving rod 7 under the limit block 5, so that the transverse force that affects the sealing between the two pipes 9 is transformed For the downward longitudinal for...

Abstract

The invention provides a two-way usable pipeline sealing device. The two-way usable pipeline sealing device comprises two discs, concave blocks and a limiting block, wherein threaded holes penetrating through the end faces of the two sides are formed in the two discs respectively, connecting blocks are fixedly mounted on the circumferential faces of the two discs respectively, sliding blocks are fixedly mounted at the tops of the two connecting blocks respectively, driving rods are hinged to the tops of the two sliding blocks respectively, the sides, away from the concave blocks, of the two driving rods are hinged to the bottoms of the limiting block, the concave blocks are provided with openings allowing the two driving rods to move, and a limiting mechanism for fixing the position of the limiting block is arranged on the concave blocks. According to the device, a screw penetrates through the limiting block and is in threaded connection with two fixed plates, and meanwhile the driving rods are hinged to the lower portion of the limiting block, so that transverse force influencing the sealing performance between two pipelines is converted into downward longitudinal force on the screw, and the sealing work of the pipelines is better through the arrangement.

Description

technical field [0001] The invention relates to the technical field of pipeline sealing equipment, in particular to a bidirectional pipeline sealing device. Background technique [0002] Pipe-pipe connection The connection method between pipes, pipe joints, valves and inlet and outlet pipes on the equipment is determined by the nature of the fluid, pressure and temperature, as well as the material, size and installation place of the pipes. There are mainly threaded connections, method There are four methods of flange connection, socket connection and welding: ① threaded connection: mainly suitable for small diameter pipes. When connecting, it is generally necessary to wrap fluorine plastic sealing tape on the threaded connection part or apply thick paint, wrap around hemp silk and other sealing materials to prevent leakage. When the pressure is above 1.6 MPa, a gasket is generally added to the end face of the pipe to seal. This connection method is simple and can be disass...
