Problems solved by technology
[0006] In the above two technologies, the throttle valve is clamped and loosened by clamping the throttle valve from the outside of the throttle valve, so that the profile of the claw clamping the throttle valve must be larger than the profile of the throttle valve. Not conducive to the miniaturization of equipment

Embodiment 1
[0066] This embodiment discloses a throttle valve grasping mechanism, and the whole and / or part of the content of the preferred implementations of other embodiments can be used as a supplement to this embodiment if no conflict or contradiction is caused.
[0067] According to a preferred embodiment, see attached figure 2 , 7 . The elastic clip 100 may include at least two claws 110 for picking and placing the throttle valve 700 . The delivery tool 200 may include a rail 210 and a running part 220 capable of moving along the rail 210 to transport the elastic clip 100 to a corresponding position where the throttle valve 700 can be taken and placed. The hydraulic unlocking component 300 may include an unlocking lever 310 that may be used to unlock and / or lock the throttle valve 700 . The other ends of the at least two claws 110 can form a first state of being closed relative to each other and a second state of opening relative to each other. The other ends of the at least tw...

A throttle valve grabbing mechanism comprises an elastic clamp. The elastic clamp comprises at least two clamping jaws. One ends of the at least two clamping jaws are fixed relative to each other, theother ends of the at least two clamping jaws can form a first state of being folded relative to each other and a second state of being opened relative to each other, the other ends of the at least two clamping jaws can stretch into a connecting opening of a throttle valve in the first state of being folded relative to each other and then move away from each other to form the second state, and therefore the elastic clamp is clamped in a clamping groove arranged in the connecting opening through outer clamping hooks of the clamping jaws to be connected with the throttle valve. The clamping jawsextends into and is clamped in the clamping groove of the throttle valve from the connecting opening arranged on the throttle valve to realize rapid connection with the throttle valve, so that the clamping jaws do not need to grab the throttle valve from the circumferential direction of the throttle valve, the size of the clamping jaws can be made smaller, smaller space is occupied, work in a narrow space is facilitated, and the clamping jaws can be connected with the throttle valve faster and more stably.
Description
technical field [0001] The present invention relates to offshore engineering equipment, more specifically, to the technical field of offshore petroleum engineering equipment, and in particular to a throttle valve grasping mechanism. Background technique [0002] A throttle valve is a valve that controls fluid flow by changing the throttle section or throttle length. Usually, in the technical field of petroleum engineering equipment, the throttle valve is connected to the throttle pipeline. By controlling the size of the throttle valve channel to create resistance to the liquid flow and generate back pressure, the fluid in the well can flow out under control. In the prior art, some christmas trees are directly immersed in water, and some christmas trees are placed in a deep-water functional cabin, and the water around the christmas tree is isolated through the deep-water functional cabin. For example, the concept of deep-water functional cabin can be found in the research on...
