Abstract
The invention belongs to the boiler pump water tool technology field and especially relates to an inner threaded pipe pump water tool. The tool comprises a positioning pin, a sealing washer, a piston, an air cylinder and a water injection interface. A cross section of the positioning pin is a T-shaped structure. A middle portion of the positioning pin is hollow. A head diameter of the positioning pin is less than a diameter of an inner threaded pipe. A tail portion of the positioning pin is located in the piston. The sealing washer is arranged between the positioning pin and the piston. A cross section of the piston is in a ''protruding'' shape. A head of the piston is embedded into the air cylinder. The water injection interface is vertically embedded into the air cylinder. The structure is simple, manufacturing is convenient, cost is low, sealing performance is good and dismounting is easy.
Description
Technical field
The invention 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 invention 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 present invention, 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 present invention, also comprise lifting jack and water-pressure platform, lifting jack is arranged between cylinder and water-pressure platform.
In the present invention, 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.
Beneficial effect of the present invention: the present invention 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 present invention loads and unloads easily, structure is simple, and safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention 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 invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
