Abstract
The invention relates to a control part of a fluid valve and particularly relates to a fast-assembly valve. The fast-assembly valve comprises a valve body, a handle, an opening-closing unit and a valve rod. The fast-assembly valve is characterized in that the opening-closing unit is arranged inside the valve body, wherein the upper part of the opening-closing unit is connected with the valve rod, valve tubes are arranged at the two sides of the opening-closing unit; a sealing ring is arranged between the opening-closing unit and the valve tubes; screw caps are arranged at the two ends of the valve tubes; an O-shaped expansion sealing pad is arranged at the inner side of each valve tube; O-shaped sealing pads are arranged between the screw caps and the valve tubes. The fast-assembly valve is convenient to use and reasonable in design; the expansion sealing pads are heated to expand for completely adhering the valve to a water tube; the O-shaped sealing pads are arranged between the screw caps and the valve tubes, so that the sealing performance during water introduction is good, and therefore, the fast-assembly valve is very convenient and quick to use, and very worthy of being popularized and applied.
Description
(1) technical field
The present invention relates to the controlling component of Fluid valve, particularly a kind of fast-assembling valve.
(2) background technique
At the critical piece that valve is in various pipes system.Existing valvular main structure major part is the Internal Pipe Thread that valve two ends place has connecting tube, when constructing, must make the external pipe thread matched with valve Internal Pipe Thread by cover, pipeline and valve could be coupled together like this on the pipeline connecting pipe network.Overlap external pipe thread processed in construction, not only take a lot of work but also require great effort; And when Pipe installing valve, if the strength of twisting crosses senior general may be split up valve, again must change and reconnect, cause the waste of manpower, goods and materials.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of simple, convenient fast-assembling valve.
The present invention is achieved through the following technical solutions:
A kind of fast-assembling valve, comprise valve body, handle, opening/closing device, valve rod, it is characterized in that: described opening/closing device is placed in valve inner, this opening/closing device top is connected with valve rod, and both sides are valve pipes; Seal ring is provided with between described opening/closing device and valve pipe; Described valve body two ends are provided with nut; O type Expansion sealing pad is provided with inside described valve pipe; O grommet type seal is provided with between described nut and valve pipe.
Described nut outer surface is provided with bar shaped tread plate.
When the present invention uses, backed out by nut, inserted by water pipe in valve pipe, heat Expansion sealing pad position a little with thermal source, Expansion sealing pad expanded by heating makes valve and water pipe fit completely; Be provided with O grommet type seal between nut and valve pipe, when making water flowing, sealing is good.
The invention has the beneficial effects as follows: the present invention is easy to use, reasonable in design, Expansion sealing pad expanded by heating makes valve and water pipe fit completely; Be provided with O grommet type seal between nut and valve pipe, when making water flowing, sealing is good, fast very easy to use, highly applies.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1, valve body, 2, handle, 3, opening/closing device, 4, valve rod, 5, valve pipe, 6, seal ring, 7, nut, 8, Expansion sealing pad, 9, O grommet type seal, 10, tread plate.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises valve body 1, handle 2, opening/closing device 3, valve rod 4, it is characterized in that: described opening/closing device 3 is placed in valve inner 1, and this opening/closing device 3 top is connected with valve rod 4, and both sides are valve pipes 5; Seal ring 6 is provided with between described opening/closing device 3 and valve pipe 5; Described valve body 5 two ends are provided with nut 7; O type Expansion sealing pad 8 is provided with inside described valve pipe 5; O grommet type seal 9 is provided with between described nut 7 and valve pipe 5.Described nut 7 outer surface is provided with bar shaped tread plate 10.
When the present invention uses, backed out by nut 7, inserted by water pipe in valve pipe 5, heat Expansion sealing pad 8 position a little with thermal source, Expansion sealing pad 8 expanded by heating makes valve and water pipe fit completely; Be provided with O grommet type seal 9 between nut 7 and valve pipe 6, when making water flowing, sealing is good.
Describe the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
Claims (2)
