Description

Christmas tree model Technical Field The utility model relates to the technical field of model construction, in particular to a christmas tree model. Background The production tree is used as core equipment for controlling wellhead production in oil and gas field development, the structural complexity and the functional integration level of the production tree directly influence the safety and the production efficiency of an oil well, and the production tree is mainly used in the aspects of simulation precision, functional verification and cost control. The christmas tree plays a vital role as wellhead control equipment. Its main function is to manage and regulate the fluid extracted from the underground hydrocarbon reservoir, ensuring the safety and efficiency of the operation. However, conventional christmas trees present challenges in terms of sealing performance, structural stability, and ease of operation. Therefore, the novel Christmas tree model is developed, so that the working efficiency can be improved, the environmental risk can be reduced, and the novel Christmas tree model is an urgent requirement for the development of the current industry. In order to simulate the working principle of the christmas tree, an equal proportion model is usually required to be built, and then oil transportation tests are carried out, but due to the complex high-pressure environment and fluid properties, the traditional sealing materials are difficult to meet the requirement of long-time use, and the leakage risk is increased. And under the condition of large vibration or pressure change, the components are easy to loosen or fall off, so that the safety of the whole system is affected. Disclosure of utility model The utility model aims to provide a Christmas tree model, which aims to solve the problems that the sealing performance is easily reduced and the verification of the model function is affected because the sealing rings are damaged when the sealing rings are used for a long time and are not replaced. In order to solve the technical problems, the utility model adopts the following technical scheme that the christmas tree model comprises a sleeve four-way, a sleeve valve is connected to the sleeve four-way, a lower flange is connected to the sleeve four-way, an upper flange is connected to the lower flange, an oil pipe four-way is arranged on the upper flange, a main valve is arranged on the oil pipe four-way, a test valve is arranged on the oil pipe four-way, a production valve is arranged on the oil pipe four-way, a clamp is arranged on the oil pipe four-way, and an oil pipe hanging jackscrew is arranged on the sleeve four-way. Preferably, the seal groove has been seted up to the lower surface of last flange, the ring channel has been seted up to the upper surface of lower flange, the internally mounted of ring channel has the ring, the ring obtains upper surface mounting and is equipped with the sealing washer, the sealing washer is laminated with the internal surface activity of seal groove, the U-shaped groove has been seted up to the internal surface of ring channel, the outside fixed surface of ring is equipped with the U-shaped piece, the U-shaped piece is laminated with the internal surface activity of U-shaped groove, the screw thread is inserted on the U-shaped piece and is equipped with the installation screw, the tip screw thread of installation screw is inserted and is established in the inside of lower flange, the recess is seted up to the upper surface of U-shaped piece, the installation screw thread is inserted and is established in the recess. Compared with the prior art, the utility model has the beneficial effects that: 1. The utility model is communicated with the pipe column through the sleeve four-way, the liquid circulation in the sleeve can be controlled through the sleeve valve, the upper flange and the lower flange can be fastened together through the bolt group, the output flow of the fluid can be regulated through the production valve, and the pressure can be monitored through the test valve. 2. According to the utility model, before the upper flange and the lower flange are connected together, the U-shaped block arranged on the outer side surface of the circular ring can be placed into the U-shaped groove, then the circular ring is connected to the lower flange through the mounting screw, and after the upper flange and the lower flange are connected together, the sealing ring enters the sealing groove, so that the sealing performance is improved, and the leakage of fluid is prevented. When the sealing ring needs to be replaced subsequently, only the mounting screw is required to be rotated, the ring with the new sealing ring is replaced, the sealing ring is fixed through the mounting screw, the stability of model function verification is improved, and meanwhile, the structural stability is enhanced so as to cope with high-pressure and vibration environments. 3.
