Abstract
The utility model relates to clamping center regulated spherical surface connecting structure for a large scale hydrostatic pressure test machine, which comprises a water flushing head, an end surface sealing pad and a supporting oil cylinder, wherein a convex spherical surface is fixedly arranged at the back end of the water flushing head, and a concave spherical surface is arranged at the front end of a stretching pull rod of the supporting oil cylinder, which contacts with the convex spherical surface to form a pair of spherical surfaces, while the spherical surface on the stretching pull rod contacts with the spherical surface connected at the back end of the water flushing head, to form another pair of spherical surfaces, a pair of contacting spherical surfaces formed by the convex spherical surface and the concave spherical surface is a pair of homocentric spherical surfaces as well as the other pair of contacting spherical surfaces formed by the spherical surface on the stretching pull rod and the spherical surface arranged at the back end of the water flushing head. The utility model has the advantages that in the process of steel tube pressure test, the utility model can perform the function of positioning the steel tube and the sealing pad as well as center-regulating function, therefore the sealing density and pressure test accuracy of the steel tube and the sealing pad are ensured, the quality, the safety and the reliability of the steel tube are improved and the service life of the steel tube is prolonged.
Description
Technical field
The utility model belongs to steel pipe pressure checking device technical field, particularly relates to a kind of pipe end of can reconciling and can realize that the tight large-scale hydrostatic test machine of two sealing structures clamps the aligning seat syndeton by automatic aligning with contacting also of sealing pad in the steel tube pressure-measuring process.
Background technology
At present after the weldless steel tube of uses such as petroleum gas industry, machinery manufacturing industry, chemical industry and metallurgy industry is made for finished product, all need the interior pressure performance of steel pipe is detected, this is because the interior pressure performance of steel pipe is directly connected to its quality and serviceable life.In detecting the pressure testing process, because the source difference of steel pipe raw material, the flatness of many raw material pipe ends is not enough, when existing pressure testing equipment at clamping positioning steel tube end face and sealing pad the time, all is to adopt to be rigidly connected owing to promote the entire mechanism of sealing pad, the flatness of steel pipe end face is not enough, so cause producing the gap between the end face of steel pipe and the sealing pad, and poorly sealed close, in the pressure testing process, seriously leak, cause pressure testing inaccurate, be difficult to guarantee pipe quality and life-span.
Summary of the invention
The utility model provides a kind of pipe end of can reconciling in the steel tube pressure-measuring process can realize that the tight large-scale hydrostatic test machine of two sealing structures clamps the aligning seat syndeton by automatic aligning with contacting also of sealing pad for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Large-scale hydrostatic test machine clamps the aligning seat syndeton, comprise: the bath head, by bolt and bath the butt-end packing dish and the rack-mounted support cylinder that are connected, it is characterized in that: be fixed with and the protruding sphere of its all-in-one-piece in a bath rear end, at the telescopic lever front end of the support cylinder concave spherical surface that has been welded, and contact with protruding sphere and to form a pair of sphere, sphere on telescopic lever contact with the sphere that is connected a bath rear end and forms another to sphere, and another of a pair of sphere formation that contacts a sphere on sphere and the telescopic lever and a bath rear end that described protruding sphere and concave spherical surface form contacts sphere and be two pairs of concentric sphericals.
The utility model can also adopt following technical measures:
The sphere of a described bath rear end is bolted to connection the bath head.
Advantage and the good effect that the utlity model has are: because the utility model has adopted two pairs of concentric spherical articulated structures between the telescopic lever of bath head and support cylinder, in the steel tube pressure-measuring process, can play the positioning action of steel pipe and butt-end packing dish, can play the aligning effect again, clamp by telescopic lever and to be suppressed steel pipe, the steel pipe end face squareness is not enough in compaction process, can regulate automatically by the rotation of each sphere.And then guaranteed that steel pipe and sealing pad seal tightly and pressure testing is accurate, and improve pipe quality and safe reliability, prolong the serviceable life of steel pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, butt-end packing dish; 2, bath head; 3, protruding sphere; 4, concave spherical surface; 5, sphere; 6, support cylinder; 7, telescopic lever; 8, sphere; 9, steel pipe.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, large-scale hydrostatic test machine clamps the aligning seat syndeton, comprise: bath 2, by bolt and bath the butt-end packing dish 1 and the rack-mounted support cylinder 6 that are connected, be welded with and the protruding sphere 3 of its all-in-one-piece in a bath rear end, at telescopic lever 7 front ends of support cylinder 6 concave spherical surface 4 that has been welded, this concave spherical surface 4 contacts with protruding sphere 3 and forms a pair of sphere, sphere 8 on telescopic lever 7 contact with the sphere 5 that is connected a bath rear end by bolt and forms another to sphere, described protruding sphere 3 and concave spherical surface 4 form a pair of contact sphere 8 on sphere and the telescopic lever 7 and sphere 5 formation another contact sphere and be two pairs of concentric sphericals.Sphere termination automatically alignment under axle pressure like this, the aligning effect in the time of can playing steel pipe and contact with sealing pad also can realize the tight reliable sealing of steel pipe and butt-end packing dish simultaneously.
Principle of work of the present utility model is:
Support cylinder 6 is packed on the frame, clamps by telescopic lever 7 and is suppressed steel pipe 9, and in compaction process, steel pipe 9 end face squareness are not enough, can be by the automatic adjustable side face seal of the rotation dish 1 of two pairs of spheres and the sealing of steel pipe 9 end faces.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
