Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving valves, in particular to an energy-saving valve air box component. Background Art

[0002] Energy-saving valve air box is an important equipment in industrial production. It combines the functions of energy-saving valve and air box, and is used to control the flow and pressure of fluid or gas in the pipeline. In the traditional air box design, it is usually manufactured by pressing and forming, that is, the upper cover and the lower seat are permanently fixed together by pressure or other means. However, although this design method can ensure the sealing and structural strength of the air box, it is often difficult to obtain effective clamping seals at the upper and lower ends of the deformation piece. During long-term use, due to the wear and aging of the deformation piece, liquid leakage is likely to occur, which not only affects the service life of the valve, but may also cause safety hazards to the entire liquid control system. Therefore, we propose an energy-saving valve air box to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide an energy-saving valve air box component, which solves the problem that in traditional air box component design, the upper cover and the lower seat are usually manufactured by a press-fit integrated molding method, that is, the upper cover and the lower seat are permanently fixed together by pressure or other means. However, although this design method can ensure the sealing and structural strength of the air box component, once the internal parts of the air box component, such as the deformation piece, are damaged or need to be replaced during use, since the upper cover and the lower seat are press-fitted into one piece, the disassembly and replacement work becomes extremely difficult, which not only increases the maintenance cost, but also affects the normal operation of the production line.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) In the utility model, the upper cover and the lower seat are positioned by the engagement between the pressing block and the extension block to achieve preliminary installation work, so that the clamping block can clamp, position and seal the deformation piece, which can not only make the deformation piece stably located between the upper cover and the lower seat, but also avoid leakage of the temperature-sensitive medium on the deformation piece, thereby improving the overall safety performance.

The pressing block 3 is clamped and connected with the extension block 4 through a pressing process, and a sealing block 5 is installed between the mutually clamped pressing block 3 and the extension block 4. A plurality of No. 2 sealing rings 15 are installed on the lower surface of the upper cover 1. The lower ends are respectively snap-fitted and installed inside the lower seat 2, and clamping blocks 16 are respectively installed on the inner sides of the upper cover 1 and the lower seat 2 and close to each other.
