Embodiment Construction

[0047] In the figures, reference numeral 1 denotes a hot stab according to the invention. Hereinafter, those parts necessary for understanding the present invention will be described while other structural details will be omitted.

[0048] The hot stab 1 comprises a fixing part which takes the form of a mandrel 2 , a sleeve 3 , a handle 40 and a nose 42 . The sleeve 3 rotatably surrounds the valve portion 29 of the mandrel 2 . The handle 40 is fixed to the connecting portion 20 , which is positioned on the mandrel 2 close to the handle 40 . Such as image 3 As shown in , the interior of the nose 42 is provided with a threaded portion, and the nose 42 is fixed to the valve portion 29 of the mandrel 2 at the threaded portion in one end of the mandrel 2 .

[0049] In the figures, in a part of the mandrel 2 it is shown that there are three fluid channels 21 extending axially as bores in the interior of the mandrel 2 . The mandrel 2 can be provided with one fluid channel 21 or ...

Abstract

An apparatus for a valve comprising: a stationary portion provided with at least one fluid port; and a rotatable sleeve provided with at least one aperture, wherein: the sleeve is configured to allow the sleeve to rotate the aperture into alignment with the fluid port , so that when the sleeve is in the open position, the sleeve allows fluid to flow through the fluid port and the bore; the sleeve is configured to allow the sleeve to rotate the bore away from the fluid port, so that when the sleeve is in the closed position, the sleeve fluid is not allowed to flow through the fluid ports; the fixed part and the casing form an annulus between the fixed part and the casing; and the annulus is axially limited by two packer elements in the axial direction of the casing and fixed part, One of the two packer elements is located on one side of the fluid port and the other of the two packer elements is located on the opposite side of the fluid port, wherein the annulus is in fluid communication with the fluid port of the fixed portion.

Description

technical field [0001] The invention relates to a valve assembly and the connection of two valve assemblies. More specifically, the valve assembly relates to shutting off liquid flow such that subsequent discharge is avoided and two components each having a valve assembly according to the invention can be separated with little force and without reducing system pressure. Background technique [0002] In order to shut off the fluid flow in the conduit, it is known to use a valve. Several types of valves are known in the art. A well-known group of valves are quarter-turn valves, including, for example, ball valves, butterfly valves, and plug valves. Ball valves are characterized in that the valve element is spherical. The valve element (referred to below as the ball) has a through opening. When the opening of the ball is aligned with the longitudinal direction of the valve (the direction defined as the direction between the center of the inlet opening and the center of the ...
