Description
Technical field
The utility model belongs to boiler pump water conservancy project packing technique field, specifically, is a kind of internal thread tube pump water conservancy project dress.
Background technology
China's power industry more and more trends towards selecting high parameter, jumbo boiler controller system, when producing these boiler components, water-pressure sealed test need be carried out to pipe, wherein some is rifled tube, because rifled tube structure is special, general employing first welds one section of light pipe, is cut off by light pipe after treating the hydraulic testing again, take steel when this method had not only been taken a lot of work, all can cause unnecessary loss from manpower or material resources aspect.
Summary of the invention
In order to solve the problems of the technologies described above, for the art provides one to be convenient to install, save the running time, the pump water conservancy project work that sealing is good, the utility model discloses a kind of internal thread tube pump water conservancy project dress, comprise register pin, packing washer, piston, cylinder and water injection interface, the xsect of register pin is T-shaped structure, the center section hollow of register pin, the head diameter of register pin is less than the diameter of rifled tube, the afterbody of register pin is arranged in piston, packing washer is provided with between register pin and piston, the xsect of piston is " convex " font, the head of piston embeds in cylinder, water injection interface embeds in cylinder longitudinal.
Further improvement of the utility model, is provided with O-ring seal between piston and cylinder, is provided with O-ring seal between water injection interface and cylinder, and O-ring seal adopts O-ring seals, can ensure the sealing between cylinder and piston, water injection interface like this.
Further improvement of the utility model, also comprise lifting jack and water-pressure platform, lifting jack is arranged between cylinder and water-pressure platform.
In the utility model, register pin diameter is slightly less than ips and loads in rifled tube, and other end is through packing washer and piston, and to guarantee in boost process, rifled tube and tooling device remain same center; Packing washer is placed in the notch of piston, and register pin is worn at center, while compressing rifled tube end, can not extend out distortion when guaranteeing boosting under the protection of piston notch; O RunddichtringO is placed, to prevent from leaking in boost process between water filling joint and cylinder, between cylinder and piston.
The beneficial effects of the utility model: the utility model is mainly through increasing the surface of contact of packing washer and rifled tube end, and increase the mode of the thickness of O-ring seal, in pump water process, serve good sealing effectiveness, the utility model handling are easily, structure is simple, and safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-register pin, 2-packing washer, 3-piston, 4-O-ring seal, 5-cylinder, 6-water injection interface, 7-lifting jack, 8-water-pressure platform, 9-rifled tube.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
Embodiment: as shown in Figure 1, a kind of rifled tube 9 pump water conservancy project dress, comprise register pin 1, packing washer 2, piston 3, cylinder 5 and water injection interface 6, the xsect of register pin 1 is T-shaped structure, the center section hollow of register pin 1, the head diameter of register pin 1 is less than the diameter of rifled tube 9, the afterbody of register pin 1 is arranged in piston 3, packing washer 2 is provided with between register pin 1 and piston 3, piston 3 xsect be " convex " font, the head of piston 3 embeds in cylinder 5, and water injection interface 6 embeds in cylinder 5 longitudinal.
In the present embodiment, be provided with O-ring seal 4 between piston 3 and cylinder 5, be provided with O-ring seal 4 between water injection interface 6 and cylinder 5, O-ring seal 4 adopts O-ring seals, can ensure the sealing between cylinder 5 and piston 3, water injection interface 6 like this.
The present embodiment also comprises lifting jack 7 and water-pressure platform 8, and lifting jack 7 is arranged between cylinder 5 and water-pressure platform 8.
The pump water process of the present embodiment: first rifled tube 9 is placed on water-pressure platform 8, each assembly of the present embodiment is in place, first use lifting jack 7 pretension to certain pressure, cylinder enters to rifled tube 9 thruster by lifting jack 7 together with piston 3, makes packing washer 2 and rifled tube 9 fit seamless, intakes from water filling joint, water is full of rear slow boosting, piston 3 is pushed ahead under stress, and packing washer 2 compresses with tube end under the effect of piston 3, and pressure more high sealing is tighter.
More than show and describe ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
