Embodiment 1

[0041] like Figure 1 to Figure 6 A specific implementation of the valve shown, the valve includes:

[0042] The valve body 1 has a valve chamber 8;

[0043] The transmission shaft 10 is rotatably arranged on the valve body 1 along the wall thickness direction of the valve body 1;

[0044] The valve plate 9 is located in the valve cavity 8 and is fixedly arranged on the transmission shaft 10, and is suitable for rotating towards both sides of the transmission shaft 10;

[0045]The elastic clamping mechanism 2, located on the outer wall of the valve body 1, includes a biasing member 21 connected to one end of the transmission shaft 10, and a clamping assembly 22 symmetrically arranged on both sides of the biasing member 21; in the clamping assembly 22 The two elastic clamping terminals are suitable for clamping the biasing member 21 to keep the valve plate 9 closed, and the valve plate 9 rotates and opens under the action of an external force to drive the biasing member 21 to...

Embodiment 2

[0062] like Figure 7 A specific embodiment of the top drive mud pipeline device provided by the present invention is shown, including a gooseneck 13 and a swimming pipeline 14, and also includes the valve in Example 1, and the valve is connected to the gooseneck 13 and the swimming pipeline 14. The gooseneck 13 communicates with the drill string 15 .

Abstract

The invention provides a valve and a top drive mud pipeline device, which belong to the technical field of top drive drilling devices. The valve comprises: a valve body with a valve cavity; on the body; the valve plate is located in the valve cavity and fixedly arranged on the transmission shaft, and is suitable for rotating towards both sides of the transmission shaft; the elastic clamping mechanism is suitable for controlling the opening and closing of the valve plate by the pressure difference on both sides of the valve plate, The top drive mud pipeline device includes a gooseneck and a swimming pipeline, and also includes the above-mentioned valve, which is connected between the gooseneck and the swimming pipeline. The valve and the top drive mud pipeline device provided by the present invention aim to solve the technical problem of preventing a large amount of mud from flowing out when the gooseneck is disconnected from the drill string, causing waste of mud and polluting the drilling platform.

Description

technical field [0001] The invention belongs to the technical field of top drive drilling devices, and more specifically relates to a valve and a top drive mud pipeline device. Background technique [0002] The top drive drilling device is the cutting-edge technology and equipment for drilling today, and has become a standard product in the oil drilling industry. The so-called top drive drilling device is to directly rotate the drill string from the upper part of the derrick space and send it down along the special guide rail in the derrick. Drilling machinery and equipment that completes various drilling operations such as drill string rotary drilling, circulating drilling fluid, connecting drill pipes, make-up and breakout, and back reaming. When drilling, the top drive drilling device feeds high-pressure mud into the drill string through the swimming pipeline and gooseneck in sequence. The drill string rotates and drills, and the high-pressure mud flows out from the drill...
