Abstract
The utility model relates to a positive and negative pressure-measuring inflator for urgent repairing construction. The utility model is composed of an inflator with large quantity and a pressure-measuring air storage pump in parallel. The utility model is an industrial manual tool which integrates inflation, inflated and air pressure measure. The utility model is used for inflating and measuring pressure for coal gas urgent repairing construction and underground cable. When the rubber and the plastic products are inflated, the utility model can replace large tools of air pumps, large air bottles, etc. The utility model has the characteristics of convenient operation, rapidity, flexibility, and multiple uses.
Description
The utility model relates to a kind of first-aid repair construction with positive and negative pressure measurement pump.
In modern gas pipe line repairing or the construction pressure measurement process, be convenient repairing and saving, be everlasting and fill in a special balloon and top off in the pipeline of job site with blocking-up coal gas source, rapidly balloon is taken out again after construction finishes and be beneficial to safety, in the modern underground telecommunications pipe network, also need in pipeline, to inflate and the while measuring pressure, Motor Vehicle commonly used is inflated the large-scale gas cylinder scene of moving in the construction before, perhaps use common inflator, a special more in addition cover pressure-detecting device uses very inconvenient.
Provide order of the present utility model a kind of convenient, fast, be suitable for field work, the positive and negative pressure measurement pump of measuring pressure simultaneously again.
The overall structure that is achieved in that positive and negative pressure measurement pump is two inflators arranged side by side order of the present utility model, and the inflator diameter is all greater than common inflator.DN is between 50-200mm.What band handle was relatively long be pump, a band barometer weak point be the gas receiver of gas storage pressure measurement.Unidirectional automatic valve is arranged at two inflators bottom, two inflators is linked up and fixed by a steel pipe, and the pump the inside is a piston, outside piston center line one groove, cover one cushion rubber on the groove.The groove two sides all is the inclined-plane, forms the angle of reciprocity 20-50 degree with the piston center line.One suction port is arranged on the inflator base, produce negative pressure during piston motion.Gas receiver top is barometer, and the side is a gas outlet valve, during piston motion, produces malleation.During inflation, the flexible pipe of balloon and gas receiver gas outlet valve link up.Carrying handle, piston moves downward, the suction port valve seals automatically, air pressure enters in gas receiver and the balloon in the inflator, the gas receiver valve seals automatically, and pressure gauge shows the balloon internal pressure, treat the pressure-display balloon the overflow pipeline blocked the coal gas source, close gas outlet valve, the repairing of pipeline and construction are carried out.After repairing finishes, the flexible pipe that is connected in gas outlet valve is connected on the suction port, opens gas outlet valve, the tension and compression piston makes gas by extracting out rapidly in the balloon repeatedly, by extracting balloon in the pipeline out, stops up the hole on the gas pipe line then, and construction finishes.The purpose of this model utility also is achieved.
The utility model is that the new tool of usefulness is inflated in the repairing of modern coal gas or other construction pressure measurement.When not having electricity and field work, replace gas cylinder, air pump or other large-scale instrument, have convenience, flexibly, the characteristics used more.
Concrete structure of the present utility model and embodiment are provided by the following drawings.
Below in conjunction with drawings and Examples the utility model is described further.
Among the figure: 1, handle 2, connecting rod 3, cushion rubber 4, piston 5, pump 6, suction valve 7, suction port 8, gas outlet valve 9, gas receiver 10, base 11, base 12, pressure gauge 13, gas storage valve 14, steel pipe 15, flexible pipe 16, balloon.
See shown in the accompanying drawing: first-aid repair construction is two inflators arranged side by side that one is long and the other is short with the overall structure of positive and negative pressure measurement pump.There is a piston (4) piston middle cover one cushion rubber (3) long pump (5) inside, and piston and handle link with connecting rod (2).Pump (5) links to each other with base (10) and screwing hermetic, and base (10) is linked to each other by steel pipe (14) with base (11), and base (11) and gas receiver (9) are an obturator.When gas by suction port (7) after suction valve (6) enters pump (5), gas can only enter in the gas receiver (9) through steel pipe (14) and gas storage valve (13).Gas receiver gas can seal at gas outlet valve (8), or this valve open, and air enters into balloon (16) back and shows pressure by pressure gauge (12).Also gas outlet valve can be connected other container measurement pressure, when needing negative pressure, only hose port be received inflator suction port (7) and get final product.
Claims (3)
1, a kind of first-aid repair construction is with positive and negative pressure measurement pump: it is characterized in that: overall structure is two inflators arranged side by side, and its working diameter is all greater than common inflator.A pump, the gas receiver of a pressure measurement is connected two inflators and fixing by a steel pipe.One groove is arranged in the middle of the pump piston, overlap a cushion rubber above, suction port is located on the base.
2, first-aid repair construction according to claim 1 is with positive and negative pressure measurement pump, and it is characterized in that: the stack shell diameter is between DN50-200MM.
3,1 described repairing drags the worker with positive and negative pressure measurement pump according to right.It is characterized in that: be in the middle of the piston that groove, groove surface and center line form an equity 20～50 degree angles.
