This utility model belongs to the technical field of cooling water tower water distribution pipelines, and relates to a device for replacing water distribution nozzles in cooling water towers. It includes two opposing clamps, each with a hollow interior forming a channel. A semi-circular slot is horizontally oriented through the bottom of each clamp, and the two clamps encircle the water distribution branch pipe through the semi-circular slot. Connecting ears are provided on the left and right sides of each clamp, and fastening bolts are installed between the opposing connecting ears. Sealing silicone layers are provided at both ends of each clamp. A metal elbow is connected to the top of each clamp, communicating with the internal channel of the clamp. A valve is installed on the metal elbow, and a nozzle is connected to the end of the metal elbow. Filter holes are provided on the inner wall of the semi-circular slot. This utility model replaces traditional welding with mechanical bolt fixing. The clamp bolts are tightened, reducing the time required for single-point modifications, minimizing downtime losses, ensuring continuous production, and saving on welding equipment, professional personnel, and anti-corrosion treatment costs. Spare parts can be prefabricated in batches.

FIELD: protective coatings.SUBSTANCE: method for forming a protective oxide-ceramic coating on the surface of products made of valve metals and alloys by the plasma electrolytic oxidation method involves immersing the product as an electrode together with a counter electrode in a bath filled with an aqueous alkaline electrolyte, and supplying rectangular pulses of anodic and cathodic voltage to the electrodes using a pulsed power source. Anode and cathode voltage pulses are supplied with a current-free pause between them, the value of which is 4.8 times the duration of the anode pulse. The amplitude values of the cathode voltage pulses range from 85 to 149 V with a pulse repetition frequency from 1000 Hz to 4000 Hz, while the current pulse repetition frequency is additionally regulated.EFFECT: obtaining oxide-ceramic coatings with specified properties under reduced energy conditions, with lower values of cathode voltage.1 cl, 2 ex

The utility model discloses a cutting device for valve metal spare processing belongs to valve metal spare processing field, aims at solving the contact characteristic of the grinding wheel and the metal valve metal spare in the cutting process under the prior art, and the scrap often will preferentially accumulate in the area that the grinding wheel first contacts the metal valve metal spare in the collecting groove, with the continuous development of processing, the scrap in the area gradually accumulates, forms the higher scrap accumulation layer, makes the scrap under the subsequent cutting difficultly slide to the deep place of collecting groove, instead easy to bounce to the scrap of accumulation and further bounce out of the collecting groove, not only leads to the scrap collection efficiency to reduce greatly, and the scrap that scatters in the collecting groove is difficult to clean, increases the labor intensity and cleaning cost of worker's problem. Including base, the upper side right -hand member of base is installed with the mounting seat, the inside upper end of mounting seat is installed with motor, and the left -hand member of motor is installed with cutting grinding wheel.
