Electric flush tank bottom ball valve

Electric flush tank bottom ball valve introduction
Electric flush tank bottom ball valve is made of Inclined stem flush tank bottom valve and electric actuator for on off control, Electric flush 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, Electric flush tank bottom ball 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 Electric flush tank bottom ball 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 flush tank bottom ball valve is mainly used in this special condition. At present, the common on-off 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 of the reactor.
 
Electric flush tank bottom ball valve aimed at the shortage and defect of the existing product design, the flush tank bottom ball valve adopts a three-stage combination structure, arc flange, the flange and valve body, respectively, compared with the traditional two chip kettle 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, will cause the 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. Inclined stem pneumatic tank bottom ball valve body is designed with the inclined valve stem, and the ball valve stem presents a 105° inclination Angle in the ball 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 ball 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.
 
Electric flush tank bottom ball valve feature
1. Vice body of Electric flush tank bottom ball valve 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 kettle.
2. The main body and the auxiliary body are symmetrically provided with seats, and the seats are provided with a curved face that matches the valve core and seals.
3. The main electric flush tank bottom ball valve body is also provided with a discharge port, which is opposite to the feed port.
4. The middle of the electric flush 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 valve stem is connected with a hand handle or an actuator.

Electric flush tank bottom ball valve working principle
Electric flush tank bottom ball valve for discharging at the bottom of the inclined pole type tank includes the main body, the auxiliary body and the reaction kettle. The auxiliary body is fixed to the main body and forms a spherical spool cavity. The auxiliary body is fixed with a connecting seat, which is connected to the auxiliary body.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.Reaction kettle of the utility model is placed at the connection seat, through the gap and the connection of stuck limit and by the slot with convex seal, the deputy valve inlet and at the bottom of the reaction kettle of curve on both sides of the surface and grooves with formation of concave spherical is conducive to the material thoroughly mixing inside the reaction kettle, reaction and from the inlet into the fully;Two seats are used to seal the ball core to the feed.
