Abstract
The utility model discloses a socket sealing device for a cast pipe water press, and belongs to the field of testing equipment for hydrostatic pressure tests of steel pipes. The socket sealing device specially comprises a floating piston and a plug, the floating piston is mainly formed by more than two pressure heads different in diameter by means of sleeving, and the left side face of each pressure head is provided with a sealing ring correspondingly. The floating piston is designed to be provided a plurality of inner and outer rings, so that the socket sealing device can correspond to cast pipes of various pipe diameter specifications in sealing, application range of the socket sealing device is widened, the structure is reasonable, productivity is improved, and labor intensity is relieved.
Description
Technical field
The utility model relates to the detection facility field of steel pipe hydrostatic pressure experiment, is specially many specifications spigot seal device for a kind of cast tube hydraulic press.
Background technique
Along with progressively the expanding of cast tube production capacity, for coordinating the high efficiency production of centrifuge, cast-iron pipe hydrostatic testing is the requisite operation of cast tube production line, and sealing pressure head is to carry out water-pressure sealed to test requisite frock.End face seal mode is a kind of main sealing means that current medium-large caliber steel pipe hydrostatic testing adopts.
Hydraulic press is a kind of detection facility for the experiment of cast tube hydrostatic pressure, the working principle of hydraulic press: cast tube is sent into hydraulic press working position, master cylinder is pressed on to be held, between the seal arrangement of socket, then with water pump to water filling in cast tube, boost and discharge water after pressurize a period of time, cast tube is sent to next station, thereby completes the work cycle of a hydrostatic test.
The ubiquitous problem of hydraulic press of using is at present exactly that the single gauge spigot seal device using during the hydrostatic test all needs to change, and has had a strong impact on manufacturing efficiency as long as change the specification of pipe in producing.Because the cast tube of different size is when detecting sealing, seal arrangement that need to be corresponding with it, therefore this time on hydraulic press equipment, we design a kind of cast tube stamping tooling that spigot seal device just can adapt to plurality of specifications caliber that do not need to adjust.Break in the past the single spigot seal device of planting specification according to traditional design, cause the complexity of remodeling, the shortcoming such as cost is higher, and manufacturing efficiency is low.
Model utility content
The technical problems to be solved in the utility model is to provide many specifications spigot seal device for a kind of cast tube hydraulic press, this device can corresponding plurality of specifications caliber cast tube sealing, improved the Applicable scope of product, and rational in infrastructure, boost productivity, reduce labor intensity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cast tube hydraulic press spigot seal device, comprise floating piston body and plug body, it is characterized in that described floating piston body is to be mainly socketed to form by the pressure head plural, diameter is different, the left surface correspondence of each pressure head arranges seal ring.
Said structure is further limited, described pressure head is the stepped shaft cylindrical body of hollow-core construction, and its boring structure is shoulder hole, and the socket mode between pressure head is inside and outside cylindrical surface adhesive, its fitting surface is provided with seal ring, and the toroidal surface place of each pressure head leaves the gap of transverse shifting.
Said structure is further limited, between the shell of outermost pressure head and floating piston body, by flange, is connected, flange coordinates with the toroidal surface place clamping of outermost pressure head.
The beneficial effect that adopts technique scheme to produce is: the utility model improves the end sealing device on hydraulic press, in jack apparatus, floating piston body being designed to inside and outside multiring structure, by plural pressure head, be socketed to form, the seal ring of a specification is set on the working surface of each ring pressure head, the cast tube of different size is when detecting sealing, do not need to change spigot seal device and just can carry out bulge test by plurality of specifications pipe, thereby improve Applicable scope of the present utility model, and boost productivity, reduce labor intensity; In addition, this reasonable in design, good airproof performance, leaves transverse shifting gap between adjacent pressure head, can adjust along with the increase of pressure, has avoided cushion rubber stressed excessive and damage too early.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1;
Wherein: 1. seal ring, 2. bolt, 3. flange, 4. pressure head, 5. seal ring, 6. plug body.
Embodiment
1 and 2 is known with reference to the accompanying drawings, the utility model is specifically related to a kind of cast tube hydraulic press spigot seal device, comprise floating piston body and plug body 6, described floating piston body is to be mainly socketed to form by the pressure head plural, diameter is different 4, and the left surface correspondence of each pressure head 4 arranges seal ring 1.
The stepped shaft cylindrical body that pressure head 4 is hollow-core construction, its boring structure is shoulder hole, the internal surface of pressure head 3 and outer surface are step-like cylndrical surface.In accompanying drawing 2, can find out there are three cover pressure heads 3 sockets, the socket mode between pressure head 4 is inside and outside cylindrical surface adhesive, its fitting surface is provided with seal ring 5, the sealing in the time of can guaranteeing relative sliding between pressure head 4.
For hydraulic pressure is too large, damage seal ring 1, the toroidal surface place of each pressure head 4 leaves the gap of transverse shifting.
Between the shell of outermost pressure head 4 and floating piston body, by flange 3, be connected, flange 3 coordinates with the toroidal surface place clamping of outermost pressure head 4.
In jack apparatus, floating piston body is designed to inside and outside many rings, the seal ring 1 of different size is set on pressure head 4 working surfaces on each ring floating piston body.Thereby realization does not insert mouth sealing device and just can carry out bulge test by plurality of specifications pipe.
The utility model is when carrying out the hydrostatic test, first master cylinder control jack apparatus and the bellmouth device by hydraulic press withstands ductile iron pipe jointly, after being full of to pipe and floating piston body, water starts supercharging, start to do the hydrostatic test, along with increasing of hydraulic pressure, pressure head 4 under pressure, in plug body 6, be moved to the left, thereby make to seal the suffered power of pipe, along with the increase of pressure, adjust, avoided seal ring 1 stressed excessive and damage too early.After 15 seconds of pressurize, pressure test completes.
Major advantage of the present utility model is, after the pipe of different size is reached the standard grade, withstands corresponding specification seal ring 1, can directly carry out the hydrostatic test, and need not change seal arrangement, thereby enhance productivity.
