The utility model relates to valve machining technical field, especially a new type valve cover. Including base, annular pipe, reinforcing surface, fixed ring and annular groove, the annular groove sets up in the base body center position, two fixed ring respectively set up on the base body, and two fixed ring respectively are close to base body both ends setting, the annular pipe sets up in the base upward operation surface. Including raw material detection, heating and material preparation, making embryo and forging, intermediate detection, trimming and shaping, cooling and cutting, welding and processing, final detection, cleaning and polishing, equipment maintenance, the utility model has the beneficial effect that: through the close connection of annular pipe and annular groove, the sealing performance of valve cover is promoted, effectively prevents medium leakage, through strict raw material detection and each link quality detection, can effectively improve the quality of valve cover, enhances its sealing property and pressure resistance, reduces the occurrence of product failure and leakage problem.

The present invention discloses a polyimide film drying device, including a drying box, a row of transmission rollers are arranged in the drying box, the film to be dried is driven by the transmission rollers, transmission seats are arranged on both sides of each transmission roller, the transmission seats on both sides are installed in the drying box through supporting mechanisms, driving mechanisms are arranged in the transmission seats on both sides, and driving rods of the driving mechanisms on both sides are correspondingly installed on both sides of the transmission rollers. The structural setting of the device is very clever, annular inner grooves are arranged on both sides of the transmission roller, and annular heating elements with uniform intervals are arranged on the transmission seats on both sides. The heating elements are suspended in the annular inner grooves, and the entire transmission roller can be heated. When the transmission roller rotates, the heating elements do not rotate in the annular inner grooves, which will neither hinder the rotation of the transmission roller nor affect the heating. This structure is more reasonable than traditional oil seal heating, water circulation heating, etc., and the direct heating effect on the transmission roller is also better.

The utility model relates to the technical field of active coke adsorption in wastewater treatment, and discloses an active coke adsorption tower for wastewater treatment. According to the invention, the output end of the lift pump is provided with a water distribution pipeline, the output end of the water distribution pipeline is provided with an adsorption tank, one end of the adsorption tank is fixedly connected with a compressed air station, and one end of the adsorption tank is fixedly connected with a macro outflow toxic channel. The adsorber assembly, the converter, the backwashing device, the overflow device, the coke feeding device and the like are special devices for the process. Wherein the adsorber assembly integrates the functions of water distribution, coke extraction and backwashing, so that the equipment structure is simplified, the equipment efficiency and practicability are improved, and the operation difficulty is greatly reduced. The water distributor adopts an eight-claw structure, and the opening area and the mixing efficiency of the water distributor are comprehensively optimized, so that the water distribution is more uniform, short flow is avoided, and the adsorption effect is better.
