Abstract
The utility model relates to an auxiliary device for the water pressure test of a cast pipe connecting pipe fitting, in particular to a seal device for the water pressure test of a pipe fitting. The seal device is provided with an upper elbow pipe and a lower elbow pipe and is characterized in that the elbow pipes are provided with connecting flanges at the roots of the adjacent pipe walls of the two elbow pipes; sealing grooves are arranged on two opposite plate surfaces of the two connecting flanges; sealing rings are arranged in the sealing grooves; the two elbow pipes are connected at the connecting flanges by adopting a plurality of bolts; two frustum pipe orifices with flanges are respectively arranged at the other ends of the two elbow pipes; a dismounting bolt is arranged in a flange hole of each frustum pipe orifice; each frustum pipe orifice is provided with a seal sealing ring on the outer pipe wall at the inner side of the flange, wherein a water inlet and an exhaust outlet are respectively arranged on the pipe wall of the frustum pipe orifice positioned on the frustum; and the seal device solves the problems that when the water pressure test is carried out on the existing cast pipe elbow, an elbow pipe fitting is easy to deform and has bad sealing performance, and is mainly used for transforming the auxiliary device for the water pressure test of the existing cast pipe connecting pipe fitting.
Description
(1). technical field: the utility model relates to the auxiliary device of cast tube connection pipe fitting hydraulic pressure test, is a kind of pipe fitting hydraulic pressure test sealing device.
(2). background technique: the hydraulic pressure test of cast tube connecting bend, existing technology are at the jointing at elbow two ends end socket to be installed, and adopt press machine to exert pressure to end socket the elbow inner chamber to be sealed fully, carry out the water filling test pressure again; The problem that exists is: a) two ends of bend pipe tools cause the pipe fitting distortion easily owing to bearing huge end socket pressure; B) when carrying out the bend pipe tools hydraulic pressure test of big caliber, because of the deficiency of end socket pressure is easy to generate leakage.
(3). summary of the invention: the purpose of the utility model is exactly the problem that will solve existing cast tube elbow existing bend pipe tools easy deformation and poor sealing performance when carrying out hydraulic pressure test, and a kind of pipe fitting hydraulic pressure test sealing device is provided.
The concrete scheme of the utility model is: a kind of pipe fitting hydraulic pressure test sealing device; It has upper and lower two joint bend pipes; It is characterized in that: every joint bend pipe is equipped with adpting flange being positioned at two joint bend pipes adjacent tube wall roots; On two adpting flanges, two plate faces in opposite directions, be equipped with seal groove, seal ring is installed in the seal groove, described two bend pipes are to adopt several bolts to constitute the connection of two joint bend pipes at the adpting flange place; The other end at two joint bend pipes is respectively equipped with two flanged (FLGD) frustum mouths of pipe; All be equipped with in the flange hole of each frustum mouth of pipe to move back and unload bolt; Each frustum mouth of pipe all is equipped with at the outer tube wall place that is positioned at the flange inboard and seals seal ring; Wherein,, a frustum mouth of pipe is respectively equipped with water intake and relief opening on being positioned at the tube wall of frustum.
The working principle of the utility model is (seeing figure Fig. 3 for details): unload several bolts 8 in the utility model; The bend pipe 6 of the utility model two joint band frustum mouths of pipe 2 is installed in two jointings of bend pipe tools 10 respectively; Wherein, The inwall that seal ring 4 is mounted in bend pipe tools 10 interfaces is sealed at the bend pipe 6 frustum mouths of pipe 2 tube wall places, and the inwall that seal ring 4 is mounted in bend pipe tools 10 another interfaces is sealed at another bend pipe 6 frustum mouths of pipe 2 tube wall places; Adopt several bolts 8 that two bend pipes 6 are connected locking at adpting flange 9 places of two bend pipes 6, two seal rings 4 at two the bend pipe 6 frustum mouths of pipe 2 places cooperations that be squeezed simultaneously, formation the utility model is to the shutoff of two interfaces in the bend pipe tools 10; Connect pressure testing device at the water intake 5 and relief opening 3 places of the frustum mouth of pipe 2 then, just can accomplish hydraulic pressure test work bend pipe tools 10; When needs withdraw from the utility model, unload the connection of several bolts 8, and utilize moving back of the frustum mouth of pipe 2 places unload bolt 1 screw the top move back effect, can easily two jointings of two bend pipes 6 from bend pipe tools 10 be withdrawed from.
The utility model is compared with existing cast tube elbow hydraulic pressure test method, and the utility model is being tightly connected of bend pipe 6 of adopting the two joint band frustum mouths of pipe 2, has realized the shutoff to two interfaces in the bend pipe tools, good seal performance, and demolition is convenient; The utility model is simple in structure, easy to operate; The utility model preferably resolves existing cast tube elbow existing swan neck when carrying out hydraulic pressure test
The problem of part easy deformation and poor sealing performance.
