The utility model is provided with a sealing rubber ring on the outer wall of the inner insert tube to improve the sealing performance; when assembled with the container tank, the positioning column is inserted into the mounting hole of the flange for positioning, and then the limiting nut and the limiting clamp are moved upward, and the limiting clamp cooperates with the mounting frame to clamp and fix the dual-phase high-alloy steel head that is easy to assemble and disassemble to improve the processing efficiency and facilitate the cleaning of the inside of the container tank. The technical solution has the following problems:

[0004] When in use, the dual-phase high-alloy steel head can be installed by cooperating with the set limit clamp plate and the mounting frame. Since the installation of the head is fixed by the limit nut and the threaded rod, and it is not convenient to enclose and protect the limit nut and the threaded rod after the installation is completed, the limit nut and the threaded rod are prone to rust after long-term use in the outside world, and it is difficult to disassemble the head, which reduces the applicability;

[0005] In view of the above problems, the utility model document proposes a duplex high alloy steel head which is easy to install. Utility Model Content

[0014] In a possible design, the outer wall of the flange ring is symmetrically provided with installation grooves in pairs, two springs are fixedly provided on one side of the inner wall of each installation groove, and a limit block for limiting and fixing the stop frame is fixedly provided at one end of the two springs.

[0015] In a possible design, positioning rods are fixedly provided on the bottom of the flange ring in pairs symmetrically.

[0016] In a possible design, a sealing ring is provided at the bottom of the flange ring.

[0017] In the present application, when in use, firstly, the positioning rod fixed at the bottom of the head body is inserted into the corresponding positioning hole on the container tank, so that the mounting hole on the flange ring can be matched with the connecting hole on the container tank, and the head body can also be matched with the container tank, which has the effect of quick positioning, is convenient for the subsequent quick installation, and improves the convenience. Then, the mounting bolts are used to penetrate the mounting holes on the flange ring and are threaded into the corresponding connecting holes, so that the head body can be fixedly installed on the corresponding container tank, which achieves the effect of easy installation and improves the convenience. At the same time, the sealing ring at the bottom of the flange ring will fit tightly with the top of the container tank, and will be compressed during the connection process, thereby filling the small gap at the connection, which can not only enhance the firmness of the connection, but also achieve a good sealing effect and improve the applicability.

[0018] The internal threaded cover is then screwed in place to allow the internal threaded cover to be easily screwed into place on the external threaded cover, thereby protecting the internal threaded cover and preventing the internal threaded cover from rusting after long-term use. This facilitates the removal of the head body and improves applicability. At the same time, the anti-skid pattern on the outer wall of the internal threaded cover is beneficial for the stable rotation of the internal threaded cover in slippery conditions, thereby improving the use effect. After the installation bolts are well protected, the limit block is pressed.
