technical field

The utility model relates to a valve, in particular to a valve for gravity separation of organic phase and water phase.

Background technique

At present, the method of gravity separation is usually used in chemical production to separate the two media of organic phase and water system. The shut-off valve is installed on the pipeline connected to the bottom of the reactor. During the stratification process, the valve remains open. When the interface between the aqueous phase and the organic phase is detected, the valve is closed to complete the stratification. However, due to the time delay in the operation process of closing the valve, part of the organic phase will be separated into the water system, which will not only fail to meet the technical requirements of fine stratification, but also increase production costs, cause environmental pollution, and cause safety hazards.

detailed description

Below in conjunction with embodiment the utility model is described in detail.

The valve of the utility model is equipped with a small-diameter conduit, a different-diameter flange, a conductivity meter, and a pneumatic ball valve on the T-shaped three-way ball valve. The small-diameter conduit and the T-type three-way ball valve are connected together through a flange, and a conductivity meter and a pneumatic ball valve are installed on the small-diameter conduit. The conductivity meter is installed above the pneumatic ball valve so that the liquid medium flows through the conductivity meter first.

The two channels of the T-type three-way ball valve of the utility model are installed on the pipeline connected to the reaction kettle, and the third channel is connected to a conduit smaller than the caliber of the valve pipeline through a different-diameter pipe flange, and a conductivity meter is installed on the small-diameter conduit. A two-way ball valve is installed below the conductivity meter. During the separation process of the organic phase and the water system, open the upper and lower channels of the valve, and when the interface between the aqueous phase and the organic phase is detected, turn the valve switch, close the lower channel, connect the upper channel and the third channel of the valve, and use small-diameter pipes Continue layering. When the conductivity meter detects the two-phase interface, the two-way ball valve is closed to complete the stratification.

In Fig. 1, the valve body 8 is installed on the discharge pipe of the reaction kettle through the flange 1 and the flange 4, and the passage direction of the ball 6 is controlled by turning the valve stem 2, so as to control the flow direction of the liquid in the valve body 8, and the movable sealing ring 5 and the fixed sealing ring 7 play a sealing role in the valve body, and the sealing ring 3 is sealed to the valve stem 2. In Fig. 2, channel 2 14 is connected to the small-diameter conduit 10 through the different-diameter flange 9. The upper end of the small-diameter conduit 10 is equipped with a conductivity meter 11, and the lower end is installed with a pneumatic ball valve 12. The pneumatic ball valve 12 is connected to the valve body 8 through a flange. In FIG. 3 , the valve body 8 has four channels, which are channel one 13 , channel two 14 , channel three 15 , and channel four 16 . When stratification starts, open the three-way ball valve, and control the direction of the channel 6 of the ball by turning the valve stem 2, so that channel one 13 and channel four 16 are the same as the transfer pipe of the reactor. At the end of the layer, turn the valve, channel one 13 is connected with the transfer pipe, channel two 14 is connected with the small-diameter conduit 10, open the pneumatic ball valve 12, and the pneumatic ball valve 12 communicates with the valve body through channel three 15, and the layering continues through this path , when the conductivity meter reading 11 changes to zero, close the pneumatic ball valve 12, close the three-way ball valve, and the stratification is completed.
