Embodiment
[0035] Embodiment: an oilfield wellhead device for synchronously opening gate valves.
[0036] refer to figure 1 , figure 2 , image 3 , Figure 4 , Image 6 , Figure 7 , Figure 9 with Figure 13As shown, it includes a wellhead device 1, a gate valve 2, a housing 3, a casing 4, a contact rod 5, a first spring 6, an outer ring gear 7, a driving mechanism 8 and a trigger mechanism 9, and the upper part of the wellhead device 1 is circumferentially passed through bolts A casing 3 is installed, and four gate valves 2 on the upper part of the wellhead device 1 are sleeved with sleeves 4 in the outer circumferential sliding type. Cooperating with the gate valve 2, a first spring 6 is connected between the outer front side of the casing 4 and the outer front side of the gate valve 2 in the circumferential direction. The outer front side is fixedly connected, and the outer and rear sides of the casing 4 are fixedly sleeved with an outer ring gear 7, and a trigger mechanism ...

The invention belongs to the technical field of wellhead devices for oil and gas development, and in particular relates to an oilfield wellhead device for synchronously opening gate valves, including a wellhead device, a gate valve, a housing, a casing, a contact rod, a first spring, an outer ring gear, a driving mechanism and a trigger Mechanism, the upper part of the wellhead device is equipped with a casing, the casing is slidingly sleeved on the outer circumference of the four gate valves on the upper part of the wellhead device, and the contact rods are fixed at intervals in the outer and front circumference of the casing. The invention pulls the driving mechanism to rotate forward, and the forward rotation of the driving mechanism drives the trigger mechanism to operate. The operation of the trigger mechanism drives the left and right outer ring gears to reverse. The rod is reversed, and the contact rod reverses to drive the gate valves on the left and right sides to reverse and open, and the oil is discharged. Similarly, when the gate valves on the upper and lower sides need to be opened, the trigger mechanism drives the casings on the upper and lower sides to move forward, which also makes the contact rod It is in contact with the gate valves on the upper and lower sides, so that the two gate valves can be opened at the same time, and the work efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of wellhead devices for oil and gas development, in particular to an oilfield wellhead device for synchronously opening gate valves. Background technique [0002] In oil extraction, there will be a large amount of oil. In order to facilitate the collection and treatment of oil, it is necessary to install a wellhead device at the position where oil is extracted to control oil, natural gas and other substances. At present, when people discharge oil, they need to separate It is troublesome to open the gate valve to discharge the oil, and the gate valve cannot be opened at the same time, resulting in low work efficiency. [0003] Therefore, it is necessary to design and develop an oilfield wellhead device capable of simultaneously opening the gate valves, which is convenient to operate and high in work efficiency. Contents of the invention [0004] In order to overcome the disadvantages that when people disch...
