Description

Technical Field

[0001] The utility model relates to the technical field of compression type pipe fittings, in particular to a carbon steel compression type pipe fitting with good sealing performance. Background Art

[0002] Compression fittings are a type of connector that uses a socket fitting with a special sealing ring to connect pipes and use special tools to compress the pipe mouth to seal and fix the pipe. The working principle of compression fittings is to insert a thin-walled stainless steel pipe into the socket of the compression fitting, and use a special compression tool to clamp the stainless steel pipe in the fitting.

[0003] When the existing pipe fittings are connected to the pipes and then clamped by a clamping tool, the pipes are prone to slippage, which causes the pipes to deviate from the position of the raw materials, resulting in poor sealing effect at the pipe connection, which is prone to leakage and affects use.

[0004] Therefore, we propose a carbon steel compression pipe fitting with good sealing performance to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3A carbon steel compression pipe fitting with good sealing performance comprises a first connecting pipe 1, a fixing joint 2 is fixedly connected to the side wall of the first connecting pipe 1, a fixing ring 3 is fixedly connected to the side wall of the fixing joint 2, a plurality of locking components are arranged on the fixing ring 3, a second connecting pipe 4 is slidably connected in the fixing joint 2, a first sealing layer 14 is arranged on the second connecting pipe 4, the first sealing layer 14 is made of soft rubber, and the sealing performance between the second connecting pipe 4 and the fixing joint 2 is improved, and a connecting ring 5 is fixedly connected to one end of the second connecting pipe 4;

[0022] A second sealing layer 15 is fixedly connected to the side wall of the connecting ring 5, which can improve the sealing performance of the connection between the connecting ring 5 and the connecting groove 6. A connecting groove 6 is provided at one end of the first connecting tube 1 close to the second connecting tube 4. The connecting ring 5 and the connecting groove 6 are matched. A sealing assembly is provided on the second connecting tube 4. The locking assembly includes a sliding cavity 7 provided on the fixing ring 3. A telescopic spring 8 is fixedly connected to the end of the sliding cavity 7 away from the fixed joint 2. A lifting plate 9 is fixedly connected to the other end of the telescopic spring 8. A clamping block 10 is fixedly connected to the end of the lifting plate 9 away from the telescopic spring 8. The clamping block 10 slides through the fixed joint 2. A clamping groove 11 is provided on the second connecting tube 4.

[0023] The block 10 and the slot 11 are matched and arranged, and the multiple blocks 10 are arranged in a wedge shape, which is convenient for the contraction of the block 10 and has a better self-locking function than a circular shape, which can prevent the second connecting tube 4 from slipping out and improve stability. The sealing assembly includes a mounting groove arranged on the side wall of the second connecting tube 4, and an external threaded tube 12 is fixedly connected in the mounting groove, and a sealing ring 13 is threadedly connected to the external threaded tube 12.
