Abstract

The invention provides a sea valve of a mud tank and solves the problem that the sea valve cannot be tightly sealed in the prior art. The sea valve comprises a handwheel, wherein the handwheel is connected with a connection lifting rod through an upper end cover bearing component; the upper end cover bearing component is externally sleeved with a support component; a flange cover component is fixed on the connection lifting rod; a lower pipe barrel valve seat is arranged at the lower end of the connection lifting rod and is positioned in a barrel body component; the barrel body component is connected with a lower barrel body component. When the sea valve of the mud tank is used, the upper end cover bearing component and a handle rotate synchronously; at that time, the connection lifting rod rises or falls synchronously to drive the lower barrel body valve seat to rise or fall; when falling, the lower barrel body valve seat is attached to the lower valve seat component, so that the sea valve is in a closed state, and the sealing effect of the sea valve is relatively good.

Description

technical field [0001] The invention relates to petroleum equipment, in particular to a seabed valve of a mud circulation control device. Background technique [0002] The mud tank subsea valve is widely used in the mud tank of the oil drilling solid control circulation system. The existing subsea valve structure forms are as follows: figure 1 shown. Its disadvantages are: after a period of use, the seal of the subsea valve is not tight when it is closed, which will cause mud mixing, and the distance between the suction port at the bottom of the subsea valve and the bottom of the tank is relatively large when it is opened, resulting in insufficient mud extraction. Contents of the invention [0003] The invention provides a mud tank seabed valve, which solves the problem of poor sealing of the seabed valve in the prior art. [0004] Technical scheme of the present invention is realized like this: [0005] A mud tank seabed valve, comprising a hand wheel, the hand wheel ...
