Description

Technical Field

[0001] The utility model belongs to the technical field of gas pressure reducing valves, and particularly relates to a butt-mounted gas pressure reducing valve. Background Art

[0002] The pressure reducing valve is an essential accessory for pneumatic control valves. Its main function is to reduce the pressure of the gas source and stabilize it to a fixed value so that the control valve can obtain stable gas source power for regulation and control. The gas pressure reducing valve is generally installed horizontally on the pipeline.

[0003] At present, gas pressure reducing valves generally need to be installed through flange docking. The flange docking requires flat end faces and no misalignment of bolt holes. However, there are more or less slight differences in the quality of flanges. In order to improve the sealing performance, they are generally used with sealing gaskets. Changes in the spacing are likely to affect the docking effect.

[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model is created, and a docking-mounted gas pressure reducing valve is provided to solve the above problems.

[0008] As a preferred embodiment of a docking-mounted gas pressure reducing valve, the docking locking structure includes two mirror-matched locking bodies, the two locking bodies clamping matching port portions, a double-headed threaded rod is arranged between the two locking bodies, the double-headed threaded rod passes through the locking bodies and extends outward, and a nut is threaded on the extended end.

[0009] By adopting the above solution, the locking body has better compatibility and is easy to assemble.

[0010] As a preferred implementation of a docking-mounted gas pressure reducing valve, the port portion extends into the assembly body, and the locking body is provided with a slot corresponding to the port portion, and the shape of the slot matches the port portion.

[0011] As a preferred embodiment of a docking-mounted gas pressure reducing valve, the locking body is provided with a guide hole corresponding to the double-headed threaded rod, and the double-headed threaded rod is slidably fitted in the guide hole.

[0012] As a preferred embodiment of a docking-mounted gas pressure reducing valve, a guide block is provided in the matching hole, a sliding groove is provided on the locking body corresponding to the guide block, and the locking body is slidably matched on the guide block.

[0013] By adopting the above solution, the guide block can realize accurate alignment of the locking body, thereby ensuring the positioning of the port portion of the gas pressure reducing valve body.

[0014] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the port parts at both ends of the gas pressure reducing valve body extend into the assembly body to realize docking assembly, wherein the two locking bodies complete the positioning of the port parts by clamping; the guide block in the assembly body is used to realize the precise alignment of the locking body, ensuring the precise fit between the card slot and the port part.
