This utility model relates to a valve seat hard seal structure, comprising a ball, a valve seat, and a valve body connected in sequence. A pre-compression assembly is provided between the valve seat and the valve body. The pre-compression assembly includes a support ring and a pre-compression member disposed between the support ring and the valve body. The valve seat is stepped, including a first stepped portion, a second stepped portion, and a protrusion on the end face of the second stepped portion near the valve body, wherein the protrusion is embedded in a groove on the support ring and a sealing ring is fitted on the unembedded portion. This utility model provides a valve seat hard seal structure in which the pre-compression assembly can provide continuous pre-tightening force, which can compensate for gaps caused by temperature changes, pressure fluctuations, or component wear, ensuring that the valve seat and the ball are always tightly fitted and maintaining a stable seal.

This application discloses an AD calcium beverage packaging bottle suitable for aseptic cold containers. The AD calcium beverage packaging bottle suitable for aseptic cold containers includes: a bottle body, the bottle body being narrower at the top and wider at the bottom, a bottle mouth being provided on the bottle body, a filling mark being provided below the bottle mouth, a grip groove being provided on the middle surface of the bottle body, the grip groove surrounding the bottle body, and an inwardly recessed anti-swelling groove being provided at the bottom of the bottle body; in order to solve the problem that ordinary beverage packaging bottles in the prior art are prone to oxidation of the liquid due to light transmission during use, this application designs a semi-transparent layer. By setting the semi-transparent layer, the overall light transmission of the bottle body can be reduced, thereby preventing the liquid from oxidizing and protecting the flavor. Furthermore, in order to avoid leakage due to compression or temperature changes during transportation, an auxiliary sealing part is further designed. By setting the auxiliary sealing part, gaps can be effectively compensated to prevent leakage.

The application provides a star feeder, and relates to the technical field of unloading equipment, which comprises a valve body, a rotating shaft, a blade and an adjusting rod, wherein the upper part of the valve body is provided with an inlet, the lower part of the valve body is provided with an outlet, and the right side of the valve body is detachably connected with an end cover; the rotating shaft is transversely arranged in the valve body; the rotating shaft is internally provided with a first guide channel, an equalizing chamber and a second guide channel which are sequentially connected; the blade is located between the inlet and the outlet; one end of the blade is in contact with the valve body, and the other end of the blade is located in the rotating shaft and connected with a first piston; the first piston is in sliding sealing cooperation with the second guide channel; one end of the adjusting rod is movably penetrated through the end cover, and the other end of the adjusting rod is located in the first guide channel and connected with a second piston; the second piston is in sliding sealing cooperation with the first guide channel; and the first piston and the second piston are filled with hydraulic oil. After the blade is worn, a controllable thrust is applied to the adjusting rod, power is transmitted by the hydraulic oil, each blade is driven to extend outward from the rotating shaft, and the gap between the blade and the valve body is compensated.

The utility model relates to a telescopic explosive bead forming dripper, the lower extreme of the top seat has an oil injection part which is distributed along the vertical direction and is narrowed into a column shape, the oil injection part has an essential oil channel which is communicated with the oil injection hole on the side surface of the top seat and has an outlet which penetrates the lower end surface, a glue liquid cavity is arranged on the upper end surface of the base, an injection hole which is communicated with the glue liquid cavity is arranged on the side surface of the base, a concentric flow column channel which penetrates the lower end surface of the base is arranged on the cavity bottom of the glue liquid cavity, the lower end of the oil injection part enters the glue liquid cavity and the outlet of the essential oil channel is opposite to the inlet of the concentric flow column channel, the top seat and the base are connected by the adjusting mechanism which adjusts the position of the outlet of the concentric flow column channel from top to bottom. Advantageous effects: the top seat and the base are connected by introducing the adjusting mechanism, and the position of the outlet of the concentric flow column channel is adjusted from top to bottom, so that the dripper can be matched with the overflow device without changing the height difference between them, a single variable is controlled, and the equipment is quickly debugged.

The utility model discloses a sealed dustproof structure of rotary oil cylinder, the right side of sealed assembly no.
