[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-5 As shown, a leak-proof steel gas pipeline joint comprises a gas pipeline joint body 1, a first protective shell 2 is sleeved on the outer side of the gas pipeline joint body 1, and the first protective shell 2 is fixedly connected to the gas pipeline joint body 1, and the left and right sides of the front side of the first protective shell 2 are hinged with second protective shells 3, and the surface of the second protective shell 3 is fixed with a connecting ring 4, and the left and right sides of the first protective shell 2 are penetrated by threaded rods 5, and a knob 6 is fixed at one end of the threaded rod 5, and the left and right sides of the gas pipeline joint body 1 are provided with reinforcing plates 7, and the reinforcing plates 7 are arranged in a semicircular shape as a whole, and the surfaces of the reinforcing plates 7 facing each other are bonded with sealing gaskets 8, and the sealing gaskets 8 are made of rubber material, and the width of the reinforcing plates 7 is greater than the width of the gas pipeline joint body 1.
[0023] Fixing blocks 9 are fixed to the upper and lower surfaces of the connecting ring 4, and a fixing bolt 10 is provided through one side of the fixing block 9, and the fixing bolt 10 is threadedly connected to the fixing block 9. When the second protective shells 3 on both sides are flipped and closed, the connecting rings 4 on both sides can be fixed by the fixing bolts 10, and then the second protective shell 3 is sleeved on the surface of another pipe joint to seal the joint.
[0024] The threaded rod 5 is threadedly connected to the first protective shell 2, and the end of the threaded rod 5 away from the knob 6 is rotatably connected to the surface of the reinforcement plate 7. The bottom of the inner wall of the first protective shell 2 and the bottom of the inner wall of the second protective shell 3 are both provided with a limiting groove 12, and a limiting block 11 is fixed below the reinforcement plate 7, and the bottom of the limiting block 11 extends to the inside of the limiting groove 12 and is slidably connected to the inner wall of the limiting groove 12. When the staff rotates the knobs 6 on both sides, the threaded rod 5 is rotated, and the threaded rod 5 moves back and forth and rotates left and right on the surface of the first protective shell 2, and the upper reinforcement plate 7 is limited by the limiting block 11 below, so that the reinforcement plate 7 can only slide left and right, so that the reinforcement plate 7 can strengthen the seal of the connection of the pipeline.
[0025] The surfaces of the first protective shell 2 and the second protective shell 3 are coated with an anti-corrosion coating, and the anti-corrosion coating is an epoxy powder coating. By coating the anti-corrosion coating on the surfaces of the first protective shell 2 and the second protective shell 3, the protective strength of the first protective shell 2 and the second protective shell 3 can be further improved, and the internal pipe joints can be effectively protected.
[0026] Guide grooves 13 are provided on the left and right sides of the top of the first protective shell 2 and the surface above the second protective shell 3. The inner wall of the guide groove 13 is inclined. When the corrosive liquid falls on the surface above the first protective shell 2 and the second protective shell 3, the guide groove 13 can guide the corrosive liquid so that the liquid can quickly slide to the two sides of the joint, thereby preventing the corrosive liquid from accumulating above the first protective shell 2 and the second protective shell 3 and also preventing the corrosive liquid from sliding on the joint surface.
[0027] Working principle: When the staff is connecting and installing the gas pipeline joint, the staff fits another pipeline joint with the surface of the gas pipeline joint body 1, and connects and fixes it through the flange on the joint. After the fixation is completed, the staff turns the knobs 6 on both sides to make the reinforcement plates 7 on both sides move toward the surface of the gas pipeline joint body 1. When the sealing gasket 8 on the surface of the reinforcement plate 7 fits the surface of the gas pipeline joint body 1 and the other pipeline joint, the staff can stop turning the knob 6 and further reinforce the joint through the reinforcement plate 7. Then the staff flips the second protective shells 3 on both sides to make the second protective shells 3 fit each other, and fixes the connecting rings 4 through the fixing bolts 10, so that the first protective shell 2 and the second protective shell 3 shield and protect the pipeline joints on both sides to prevent external corrosive substances from corroding the joints.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
