A reinforced structure of a flexible opening of a water supply pipeline pressure test valve is shown in figures 1 and 2 and comprises a first pipeline 1 and a second pipeline 2 which are in butt joint, wherein a test valve and a flexible opening (hereinafter referred to as a flexible opening structure) are arranged between the first pipeline and the second pipeline. The first pipeline is sleeved with a first locking flange 4 and a first connecting flange 5, and the first connecting flange is positioned on one side, close to the flexible opening structure 3, of the first locking flange; one side of the first connecting flange, which faces the first locking flange, is provided with a clamp ring 6, and the clamp ring is provided with a plurality of expansion joints along the axial direction.
The first locking flange is sleeved on the compression ring of the first connecting flange, and the compression ring is locked through the fastening bolt 7 between the first connecting flange and the first locking flange (the flange plate structure), so that the expansion joint of the first connecting flange is narrowed, and the compression ring is clamped on the outer wall of the first pipeline.
The second pipeline is sleeved with a second locking flange 8 and a second connecting flange 9, and the second connecting flange is positioned on one side, close to the structure at the flexible opening, of the second locking flange; one side of the second connecting flange, which faces the second locking flange, is provided with a clamp ring, the clamp ring is provided with a plurality of expansion joints along the axial direction, the second locking flange is sleeved on the clamp ring of the second connecting flange, and the clamp ring is locked by fastening bolts between the second connecting flange and the second locking flange (the flange plate structure), so that the expansion joints of the second connecting flange are narrowed and the clamp ring is hooped on the outer wall of the second pipeline.
A plurality of soft mouth protective belts 10 are fixed between the first connecting flange and the second connecting flange. Gentle mouthful of protective zone can consolidate gentle mouthful of department structure, can also absorb gentle mouthful of department vibration, reduces the influence that the gentle mouthful of department vibration of pipeline brought by a wide margin.
The soft mouth protection belt is made of a steel belt. Usually, the gentle mouthful of protecting band both ends of aforesaid are welded fastening respectively in first flange and second flange, guarantee the reliability of connecting, when needs are dismantled, directly cut open gentle mouthful of protecting band (and flange and locking flange) can. Through the flange structural design of locking formula, be exactly avoid causing local stress to produce in the outside welding of pipeline, avoid causing the damage to the pipeline to influence pipeline safety.
Usually, each soft mouth protection belt is arranged uniformly in the outer circumferential direction of the soft mouth. The fastening bolt is a full-thread bolt. And the expansion joints on the first connecting flange compression rings are uniformly distributed in the outer circumferential direction of the first connecting flange compression rings. And expansion joints on the second connecting flange clamping rings are uniformly distributed in the outer circumferential direction of the second connecting flange clamping rings.
The inner wall of the compression ring of the first connecting flange is provided with anti-skid grains or bulges. And anti-skid grains or protrusions are arranged on the inner wall of the compression ring of the second connecting flange.
In an alternative embodiment, as shown in fig. 3 and 4, an auxiliary support frame 11 may be disposed on each side of the flexible mouth structure, and the auxiliary support frame includes an upper connecting flap 12 and a lower connecting flap 13, the upper connecting flap is provided with an upper connecting portion 14 on each side, the lower connecting flap is provided with a lower connecting portion 15 on each side, the upper connecting portion and the lower connecting portion are fixed by a connecting bolt 16, and both the upper connecting flap and the lower connecting flap are smaller than 1/2, i.e. there is a gap between the upper connecting flap and the lower connecting flap, and the upper connecting flap and the lower connecting flap are not in direct contact. In addition, a plurality of support rings 20 are respectively arranged on the upper connecting petal and the lower connecting petal, extension arms 21 are arranged corresponding to two sides of the support rings, and an adjusting ring 17 is arranged on one side of each extension arm facing the pipeline.
By way of example, the adjustment ring is mounted on a fixed mount 18, which is mounted on the extension arm via an adjustment member 19, typically a screw or bolt. The fixing base is driven to move towards one side close to the pipeline by screwing the adjusting piece, so that the soft mouth protective belt penetrating through the adjusting ring is tightened, and the protective effect of the soft mouth protective belt can be improved to the maximum extent. It should be noted that when adjusting the adjusting member on the test valve and the flexible mouth side, it is preferable to press the side flexible mouth protection belt against the structure on the test flexible mouth to improve the reinforcing effect.
When arranging gentle mouthful of protecting band, gentle mouthful of protecting band passes the adjusting ring of support ring one side, support ring and support ring opposite side in proper order, is convenient for utilize the regulating part to tighten the regulation operation to gentle mouthful of protecting band.
After the connecting bolt is screwed and fastened, the upper connecting flap and the lower connecting flap are close to each other, the supporting ring on the upper connecting flap and the lower connecting flap forms pulling to the flexible mouth protecting belt which is arranged in the supporting ring in a penetrating mode, the flexible mouth protecting belt is prevented from being loosened and suspended, and the protecting belt directly acts on the structure of the flexible mouth.
Generally, the upper connecting flap and the lower connecting flap are both arc-shaped structures, 3-5 auxiliary supporting frames are arranged on the upper connecting flap along the outer side surface of the connecting flap at intervals, and 3-5 auxiliary supporting frames are arranged on the lower connecting flap along the outer side surface of the connecting flap at intervals. It should be noted that, it is not necessary to make each soft mouth guard band pressure equalizing soft mouth department structure, and a better protection effect can be achieved as long as a certain number of soft mouth guard bands are ensured to press the valve and the outer side of the soft mouth.
The flexible opening protective belt has the advantages that the structural design is reasonable, the two ends of the flexible opening protective belt are respectively fixed on the first connecting flange and the second connecting flange, the connection reliability is high, the flexible opening structure is effectively reinforced through the flexible opening protective belt, the stability of the flexible opening structure is improved, and the adverse effect of vibration at the flexible opening on a pipeline is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
