Manufacturing Process of Inclined Rod Insulating Pub Bottom Ball Valve Pub Bottom Discharge Ball Valve
Alternative name: Pub bottom discharge ball valve
Overview of Pudi ball valve:
The inclined rod type insulated bottom ball valve is connected to the bottom of the reactor or storage tank and other containers by means of the flange (flange) welding or flange at the bottom of the valve. Therefore, the residual phenomenon of the process medium at the outlet of the container is eliminated, and the discharging and discharging functions are realized. The inclined stem Pudi insulation ball valve is applied to the discharge of reaction vessels in clean industries such as pharmacy, biology, fine chemicals, food, etc. The Pudi ball valve has the advantages of no dead corner, no residue, no leakage, good sealing performance, etc.
Inclined rod insulated bottom ball valve (with sampling valve)
Manufacturing process of discharge ball valve at the bottom of the bus:
1. Inclined valve rod: the platform and valve body are inclined at 105 ° to avoid interference between actuator and tank bottom.
2. Platform: ISO5211 standard connection, which can directly install the brake actuator.
3. Arc flange: arc welding flange and valve body form a three piece structure, which is convenient for installation and maintenance.
4. Sphere: When the sphere is closed at 90 °, the sphere is connected with the arc flange to reduce material accumulation.
5. The inner cavity of the valve body is finished, and the material flows smoothly.
6. The platform belt is adjusted to adjust the packing seal.
The inclined rod type insulated bottom ball valve includes a sphere, an arc flange, a valve stem, and the valve body is fixedly welded with the reactor through the arc flange. One end of the switch sphere extends out of the discharge end and into the head of the reactor. When the materials in the reactor react, the switch sphere acts as the bottom of the reactor, and the materials fully react in the reactor; When the reaction of the materials in the reaction kettle is completed, the switch sphere opens, and the materials enter the discharge end from the head, and then discharge from the discharge end. Compared with the ball valve structure in the existing technology, the Pudi discharge ball valve provided by Shanghai Yonglong Valve Factory can largely avoid the formation of dead zone space because it uses the switch sphere that extends out of the discharge end, exposing the sphere, The materials in the reactor have sufficient stirring reaction effect.
1. First, weld the arc flange on the tank bottom.
2. Insert the seal into the flat groove of the bonnet.
3. Screw the connecting bolt onto the arc flange.
4. After selecting the correct position of the valve driving part, align and insert the flange bolt hole with the bolt.
5. Ensure that the outer circle of the arc flange is aligned with the outer circle of the valve cover, and the nut corresponding to the screwed flange is flush with the valve cover, and the installation is completed.
6. Connect the insulation pipe with the inlet of the discharge ball valve.
Inclined stem type bottom insulation ball valve (with sampling valve)
"Shanghai Yonglong Valve Factory" slant bar type thermal insulation ball valve at the bottom of the bus is made of PPL or MOC sealing materials, which is more wear-resistant and temperature resistant. It is applicable to the tank bottom valves for emptying and discharging pressure vessels, storage tanks and other equipment, more used in reaction pots in fine chemical, pharmaceutical and chemical industries, and can also be used to transport fine and soft granular media.
