Tank bottom ball valve

Tank bottom ball valve introduction

Tank bottom valve also known as bottom ball valve, flush bottom ball valve,discharge ball valve which is installed in reaction tank bottom, aimed at the shortage and defect of the existing product design,the new three-step design tank bottom ball valve which adopts a three-stage combination structure, arc flange, the flange and valve body, respectively, compared with the traditional two pieces tank bottom ball valve, installed in the bottom of a tank during the welding process, due to the high metal material coefficient of thermal conductivity, easy to cause the seat sealing ring is damaged, which will cause the ball valve leakage.When installing the new type of inclined pole tank bottom ball valve, first take off the arc flange and weld with the tank bottom, and connect with the valve body with bolts. The tank bottom ball valve body is designed with the inclined valve stem, and the valve stem presents a 105° inclination Angle in the valve body pipe. This structural design avoids the contact between the installation actuator and the tank bottom.No accumulative material design, the spherical surface design, when the valve is closed, the spherical arc at the bottom of the tank arc flange to maintain, forming a no dead Angle connection, to avoid substance residue.

The tank bottom ball valve is welded or connected to the bottom of the reactor or storage tank and other containers by means of the bottom flange (flange) of the ball valve, so as to eliminate the residual phenomenon of the process medium usually at the outlet of the container, and realize the function of empting and discharging.

Tank bottom ball valve working principle

The tank bottom ball valve is mainly used for opening and cutting materials at the bottom of the tank. At present, in the chemical industry, medicine and other fields, bottom feeding valve is the key equipment of the reactor, which is required to be fully fitted to the inner wall of the reactor. The materials in the reactor must be fully reacted without any material stored.When the discharge valve at the bottom of the tank is cut off, ensure that there is no leakage of materials, so as not to adequately react the materials into the next process.The new type of tank bottom ball valve is mainly used in this special condition. At present, the common on-off ball valve on the market cannot fit the inner wall of the reactor due to the limitation of its structure, and has the disadvantages such as large dead Angle and poor sealing performance, which cannot meet the special requirements of bottom feeding and discharging of the reactor.
 

Tank bottom ball valve feature

1. Tank bottom ball valve, vice body, including the main body reactor flange, vice body fixed connection with the main body and form a spherical cavity of valve core, whose character is: vice body has fixed connection, connection seat with gap, the depth of the notch is greater than the second gap, respectively on the reaction kettle has a connection to a hole, the second gap joint department, the second connection department, set up at the second gap is connected with the second part have a reciprocal bulge with card slot, vice body also is equipped with inlet, feed on either side of the mouth radian on the surface of the same as the radian of the bottom of the reaction kettle;The spool chamber is provided with a spherical spool, and the top of the spool is provided with a groove, the groove and the upper surface of the auxiliary valve body smooth transition and form a concave sphere with the upper surface of the auxiliary valve body and the reaction tank.
2. The main body and the auxiliary body of the tank bottom ball valve are symmetrically provided with seats, and the seats are provided with a curved face that matches the valve core and seals.
3. The main tank bottom ball valve body is also provided with a discharge port, which is opposite to the feed port.
4. The middle of the tank bottom ball valve core is provided with a discharging hole, which forms a discharging channel with the feeding port and discharging port vertically. The side of the valve core is connected with a valve stem, which is set horizontally, and the end of the tank bottom valve stem is connected with a hand handle or an actuator.

Tank bottom ball valve installation

1. First confirm the size of the arc flange and the connection part at the bottom of the tank. After confirming that the size is completely consistent, weld the arc flange at the bottom of the tank.
2. Screw the connecting bolts on the curved flange.
3. Insert the seal into the groove of the bonnet plane.
4. Insert the flange bolt hole in line with the bolt after selecting the correct driving position of the valve
5. Make sure that the arc flange outer circle is aligned with the tank bottom ball valve cover, and screw the nut accordingly until the arc flange and the tank bottom ball valve cover are flat to complete the installation
