The flange is usually composed of two corresponding flanges, each with the same number of holes, which are used to fix the two flanges together with bolts and nuts to form a sealed connection. In the process of pipe connection, two-hole flat connection flanges are often needed.

It solves the problem that during the installation process of the existing connecting flange proposed in the above background technology, most of the workers use screws to fix the flange. If the flange is fixed with screws alone, it will become loose after being used for too long and affect the sealing between the flange and the connecting pipe fittings.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a two-hole planar connecting flange, comprising a connecting disk 1, the bottom of the connecting disk 1 is equidistantly fixedly connected with a clamping block in a circular array, the top surface of the connecting disk 1 is equidistantly threaded with a fixing bolt, the surface of the fixing bolt is threadedly connected with a connecting disk 2, the top surface of the connecting disk 2 is equidistantly provided with clamping grooves, the inner bottom wall of the clamping groove is provided with a sliding groove, both sides of the inside of the sliding groove are fixedly connected with a spring, the top of the spring is fixedly connected with a stop block, and a reinforcing disk is provided inside the connecting disk 1.

[0006] Optionally, a fixing ring is fixedly connected to the middle of the top surface of the second connecting disk, and the material of the fixing ring is carbon steel.

[0007] Optionally, the top surface of the second connecting plate is provided with threaded holes in an annular array at equal intervals, and the threaded holes are adapted to the fixing bolts.

[0008] Optionally, the clamping block is clamped with the blocking block, and the outer surface of the connecting plate 1 is provided with a waterproof coating.

[0009] Optionally, a sealing ring is sleeved on one side of the surface of the fixing ring, and the sealing ring is made of a high temperature resistant material.

[0010] Optionally, the structure of the second connection disk is the same as the internal structure of the first connection disk, and a sealing ring is provided in the middle of the top surface of the first connection disk.

[0011] The utility model provides a two-hole plane connecting flange, which has the following beneficial effects:

[0012] 1. The two-hole plane connecting flange, through the arrangement of the clamping block, the spring and the stop block, can align the connecting disk one and the connecting disk two when the staff installs the connecting disk one and the connecting disk two, and then the clamping block is inserted into the inside of the clamping groove, and the clamping block pushes the stop block downward, so that the bottom of the clamping block and the stop block are mutually abutted and clamped, and the spring drives the stop block to move upward, so that the connecting disk one and the connecting disk two are quickly clamped, thereby improving the stability of the connection between the connecting disk one and the connecting disk two, and reducing the occurrence of accidental loosening of the connecting disk one and the connecting disk two due to long-term use.

[0013] 2. The two-hole flat connecting flange is provided with the connecting plate 1, the reinforcing plate and the connecting plate 2. When the staff uses the connecting plate 1 and the connecting plate 2, the connecting plate 1 is exposed to the air for a long time. Some factors in the air corrode the inside of the connecting plate 1 and the connecting plate 2. The reinforcing plate isolates the external factors, thereby increasing the service life of the connecting plate 1 and the connecting plate 2. BRIEF DESCRIPTION OF THE DRAWINGS
