The invention discloses an EGR valve with a heating water cavity and relates to EGR valves. The technical problem that an existing EGR valve is likely to be frozen in severe cold regions is mainly solved. The EGR valve with the heating water cavity comprises a valve body, and further comprises a shell wrapping the valve body. The heating water cavity is formed in a clearance between the valve bodyand the shell, and a water inlet and a water outlet communicating with the heating water cavity are formed in the shell. The invention further discloses a heating method of the EGR valve with the heating water cavity. According to the EGR valve with the heating water cavity and the heating method, cooling water of an engine is introduced into the heating water cavity, the cooling water is circulated between the heating water cavity and the engine to heat the valve body, and the problem that the EGR valve is frozen in the severe cold regions can be effectively solved.

The invention discloses an oil tea fruit shell powder adding agent and a preparing method and application therefore, and relates to an adhesive adding agent and a preparing method and application thereof. The problem that existing aldehyde adhesive difficultly glues a straw-based panel effectively, and panel sticking exists in isocyanate adhesive is solved. The adding agent comprises modified oil tea fruit shell powder and modified nano-montmorillonite. The method comprises the steps of firstly, preparing of modified oil tea fruit shell powder; secondly, preparing of the modified nano-montmorillonite and thirdly, preparing of the oil tea fruit shell powder adding agent. The modified oil tea fruit shell powder obtained through the method is added into the adhesive, the straw-based panel is bonded, the gluing strength and water resistance are improved, and the agent is used for the field of the straw-based panel adhesive adding agent.

The invention discloses a method for threading a connecting line of a power distribution cabinet, comprising the following steps: S1, clamping the front end of the connecting line with the front jaw, clamping the rear end of the connecting line with the rear jaw, and clamping the logo with the pipe jaw Pipe; S2, move the pipe gripper, so that the identification pipe is inserted into the front end of the connection line from the front end of the connecting line; S3, open the front gripper, and move the front gripper to avoid the pipe gripper; S4, the pipe gripper grips the identification pipe Move to the rear end of the connecting line and the front of the rear jaw; S5, the front jaw moves and resets, and clamps the front end of the connecting line; S6, moves and resets to the next marked pipe clamp installation position after the pipe jaw is opened. The invention can automatically, accurately and efficiently thread the marking tube on the connecting line.

The invention relates to the technical field of engines, in particular to a pure gasoline engine assembly. The pure gasoline includes an engine unit and a carburetor, the engine unit is provided with an air intake channel, and the carburetor is installed at the air intake channel and communicated with the air intake channel; the pure gasoline engine assembly is also Including a lubricating pipeline, the engine unit has a chamber for storing organic oil mist, the carburetor includes a body and an enrichment valve body, the body is provided with an enrichment valve hole, and the enrichment valve body is slidably installed on the The enrichment valve hole is used to extrude or suck fuel; one end of the lubricating pipeline communicates with the chamber, and the other end communicates with the enrichment valve hole, so that part of the oil in the chamber Mist can flow through the lubrication line to the enrichment valve orifice. The invention has the advantages of effectively improving the stagnation problem during the movement of the enrichment valve body and improving the overall working performance of the engine unit.

The invention discloses a novel medical composite polymer material aqueous dispersion for preparation of sustained-release fine grains in a spray drying process, so that the problem of wall sticking when a single common polyacrylic resin aqueous dispersion is adopted for spray drying can be solved, and the drug product yield can be increased. The composite polymer material aqueous dispersion is simple in composition, convenient and controllable to prepare and uniform in granularity distribution, and is suitable for preparing sustained-release fine grains by the spray drying method; the prepared sustained-release fine grains have the characteristics of remarkable sustained-release effect, stable product quality, safety and environmental-friendliness, and the like, and are easy for industrial production.

The invention discloses a cetirizine hydrochloride tablet, which is prepared by the following method: dissolving cetirizine hydrochloride and polybutylene oxide stearate in ethanol, adding diatomaceous earth into the solution, stirring evenly, The obtained mixture is dried, then mixed with silicified microcrystalline cellulose, disintegrant and lubricant, and compressed into tablets. The cetirizine hydrochloride tablet prepared by the method has rapid dissolution, no sticky punch, and no corrosion to the die.
