New description: [New technical field] The present invention relates to a joint, in particular to a linear pressure balanced expansion joint. [Prior Art] The use of official roads to transport various fluids has become a commonly used transportation method. In order to cope with various high temperature and high pressure conveying conditions, it is necessary to connect and retract the joints in the pipeline. The main effect is in force 0 and The expansion or contraction of the pipeline due to temperature changes can prevent the pipeline from expanding and contracting, and the bending or contraction becomes short and breaks or breaks, resulting in fluid leakage in the pipeline. There are many types of existing expansion joints. Referring to the figure, the existing pressure balanced expansion joint 1 is connected with a second wave between the two first bellows ,1, and the second s 12 ' The flange 13 (4) on the outer side of the first bellows n is connected to the pipelines (not shown) on both sides, and the balance ratio of the first and second bellows u and i2 is used to balance the internal pressure. Thrust effect. However, the two first bellows u are directly extended from the two ends 4 of the second bellows ^, so that the overall length of the expansion joint ι is longer 'When the distance between the two sides of the pipe is smaller than the The overall length of the expansion joint 1 is made. The mysterious expansion joint 1 & method is known to be between the pipes, although the expansion joint! It can be stretched, but if it is to be compressed and placed between the pipes, other components are needed to compress the expansion joint i, which will generate extra force on both sides of the pipeline and its support. On the frame (not shown), the pipeline and the support frame are damaged; in addition, even if compressed, 3 can only slightly reduce the length of the expansion joint 1 scallop 1 and cannot be applied to the pipelines on both sides. A situation where the spacing is small. [New content]: The purpose of this novel is to provide a linear pressure-balanced expansion joint that can reduce the overall length. "Therefore, the linear pressure-balanced expansion joint of the present invention comprises a second fencing, a first bellows respectively fixed to the flange and the stones are left and facing each other, and two are located at the first bellows. Between the stalk and the second bellows disposed on the outside of the yoke frame. Each frame is fixed to the corresponding first - the bellows is away from the flange: The simplification and positioning frame are located at opposite ends of each locating frame, and the female yoke has a first fixing fixed to the first bellows end and a folded by the outer circumference of the first positioning ring a second positioning cylinder extending along the outer side of the corresponding -= tube, each second positioning cylinder partially overlapping the corresponding first bellows. The second bellows is disposed outside the two positioning brackets, so The first: the bellows is also partially overlapped with the first bellows, and the two ends of the second corrugated officer are respectively fixed on the two positioning brackets. The effect is that 'by the arrangement of the (four) positioning bracket, The tube is overlapped with the first-corrugated (four) portion, so that the overall length of the reduced joint can be greatly reduced. The above-mentioned and other technical contents, features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiments with reference to the drawings.

As shown in FIG. 3, each of the positioning brackets 23 is fixed on one end of the corresponding first corrugated portion 22 away from the flange 21, so that the flange 2 and the positioning frame 23 are located at each of the positioning brackets 23. The opposite ends, and each of the positioning brackets 23 has a first positioning ring 23 i fixed on the end of the first bellows 22 - and a bending and corresponding along the outer circumference of the first positioning ring 23 A second positioning cylinder 232 extending outside the first bellows 22, each of the second positioning cylinders 232 partially overlapping the corresponding first bellows 22. The second bellows 24 is disposed outside the two positioning brackets 23, so that the second bellows 24 is also partially overlapped with the first bellows 22, and the two ends of the second bellows 24 are respectively fixed. The second positioning cylinder 232 is disposed on the second positioning frame U. Each supporting unit 25 includes a first supporting piece 251 extending radially outward from one of the flanges 21, and a second extending radially outward from the second positioning barrel 232 of the positioning frame 23 adjacent to the other flange 21. a supporting piece 252, a connecting rod 253 penetrating the first and a supporting pieces 251, 252, and two nuts 254 screwed on the connecting rod 253 and located outside the first and second n mu respectively 'The movement of the second nut 254 on the connecting rod 253' can push the second supporting piece 25丨, 252 to move, and adjust the position of the first and second supporting pieces 251 and 252 on the connecting rod 253. Since the two swinging pieces 251 and 252 are respectively fixed on the second positioning cylinder 232 of the flange 21 and the positioning frame 23, the first and second supporting pieces 251 and 252 interlock the flange 21 and the second positioning cylinder. 232, further fine-tuning the length of the expansion joint 2. One end of one of the guide tubes 26 is fixed on one of the flanges 2 1 and the other end of the guide tube 26 is fixed on the first positioning ring 23 远离 of the positioning frame 23 away from the other flange 21 . The two guide tubes 26 extend in the same direction and collectively define a flow passage 261 for fluid flow. It is to be noted that in the present embodiment, the two guide tubes 26 are provided as an example. Of course, the number of the guide tubes 26 can be adjusted according to the actual manufacturing situation, and is not limited thereto. In use, the expansion joint 2 is placed in the joint space between two pipes (not shown), and the two flanges 21 are respectively coupled with the two pipes to be connected to each other. When the pipe flows and flows through the flow passage 261, the expansion joint 2 can be provided to balance the pressure. With the above design, the present linear pressure balanced expansion joint 2 has the following advantages in practical use: (1) reduction of the overall length: through the positioning frame 23 and the first bellows 22 are partially overlapped, and The second bellows 24 is fixed on the two positioning brackets 23 and disposed outside the second positioning frame 23, so that the second bellows 24 is, and the L/, 'military 22 portions overlap. Reduce the overall length and defeat * for a narrower joint space. (2) Modular design: - Through the setting of the swing sheet & 25, the structural strength of the expansion joint 2 can be effectively improved, so that the first and second bellows 22, 24 are not easily deflected. The nut 254 of the selecting unit 25 can adjust the position of the first and second branch pieces 251 and 252 on the connecting rod 253 to fine-tune the length of the 4 expansion joint 2, so that the expansion joint 2 is modularized. The design allows for fine-tuning of the length without the need for additional components. (3) Reducing the resonance: & the expansion joint 2 defines the μ track 261 through the arrangement of the guide tube 26, so that the fluid does not directly impinge on the first bellows 22 when flowing through the flow path 261 Moreover, the opportunity for the first bellows 22 to resonate can be effectively reduced. In summary, the present invention is configured such that the first corrugated portion 24 is partially overlapped with the first bellows 22 by the positioning frame 23, so that the large telescope can reduce the length 2 of the far telescopic joint 2 (four). I is suitable for the narrower 5 workrooms. At the same time, the overall modular design not only can reinforce the structural strength, but also can be used to achieve the purpose of this new type.
