Inclined rod type bottom discharge ball valve
English: Bottom Ball Valve
Alternative name: discharge ball valve Pub bottom ball valve Tank bottom ball valve
Model: FDQL41-16P
Overview of Pudi ball valve:
FDQL41-16PDN50 Pub bottom discharge ball valve is mainly used to open and cut off the materials at the tank bottom/Pub bottom. At present, in the chemical, pharmaceutical and other fields, the Pub bottom discharge valve is the key equipment of the reaction kettle, which is required to fully fit the inner wall of the reaction kettle, and the materials in the kettle must be fully reacted without material storage. When the discharge valve at the bottom of the bus is cut off, ensure that there is no leakage of materials, so as to prevent the materials not fully reacted from entering the next process. The new type of discharge valve at the bottom of the reactor is mainly used for this special working condition. At present, the common on/off valve on the market cannot fit the inner wall of the reactor due to structural limitations, and has the disadvantages of large dead angle, poor sealing performance, etc., which cannot meet the special requirements of the discharge valve at the bottom of the reactor.

Technical features of discharge ball valve:
1. The new type of bottom discharge ball valve includes the main valve body, auxiliary valve body and reactor flange. The auxiliary valve body is fixedly connected with the main valve body to form a spherical valve core cavity, which is characterized in that: the auxiliary valve body is fixed with a connection seat, which is equipped with a first notch and a second notch. The depth of the first notch is greater than the second notch, and the reactor is equipped with a connection seat that is respectively connected with the first notch The first connecting part and the second connecting part of the second notch fit together, and the second notch and the second connecting part are provided with mutual matching bulges and slots. The auxiliary valve body is also provided with a feed inlet, and the radian of the surface on both sides of the feed inlet is the same as the radian of the bottom of the reaction bus; The valve core cavity is provided with a spherical valve core, and the top of the valve core is provided with a groove. The groove smoothly transits with the upper surface of the auxiliary valve body and forms an concave spherical surface with the upper surface of the auxiliary valve body and the reaction kettle.
2. The main valve body and the auxiliary valve body are symmetrically equipped with valve seats, and the valve seats are equipped with arc surfaces matching with the valve core.
3. The main valve body is also equipped with a discharge port, which is opposite to the feed port.
4. The middle part of the valve core is provided with a discharge hole, which forms a discharge channel with the feed inlet and discharge outlet when it is vertical. The side of the valve core is connected with a valve stem, which is horizontally arranged, and the end of the valve stem is connected with a handle or an actuator.
The new type of bottom discharge ball valve includes the main valve body, auxiliary valve body and reaction kettle. The auxiliary valve body is fixedly connected with the main valve body and forms a spherical valve core cavity. The auxiliary valve body is fixed with a connection seat which is connected with the auxiliary valve body. The upper surface of the auxiliary valve body is arc-shaped and the radian is the same as the radian of the bottom of the reaction kettle; The valve core cavity is provided with a spherical valve core, and the top of the valve core is provided with a groove. The groove smoothly transits with the upper surface of the auxiliary valve body and forms an concave spherical surface with the upper surface of the auxiliary valve body and the reaction kettle. The reaction kettle in the utility model is placed on the connection seat, the limit position is clamped through the notch and the connection part, and is sealed with the clamping groove through the bulge. The concave spherical surface formed by the matching of the arc surface on both sides of the auxiliary valve body feeding port and the arc surface and groove on the bottom of the reaction kettle is conducive to the full mixing of the materials in the reaction kettle, the full reaction and sliding in from the feeding port; Two valve seats are used for sealing to ensure the sealing effect of the ball core on the feed.
