Abstract
The utility model relates to a safety auxiliary air inflation device with a pressure-limiting function. The utility model is characterized in that the device is mainly composed of a three-way pipe and a press limiting spring, wherein, a piston seal valve is arranged in the side pipe of the three-way pipe; the press limiting spring is arranged between the seal valve and a spring plug; an air overflow port is arranged on the pipe wall of the side pipe. The device is adopted, the normal inflation process is not influenced, and simultaneously the utility model has the advantages of simple structure, high safety, stable inflation press and wide application range; the utility model can effectively control and guarantee stable air pressure in a container; the utility model is a small auxiliary air inflation device combined novelty, reliability and safety into a whole body.
Description
The utility model relates to a kind of safe supplemental inflatable device that is mainly used in the gas replenishment process, specifically refers to a kind of safe supplemental inflatable device with pressure limiting function.
When utilizing air pump or various pump to inflate to inflatable objects, often need to grasp preferably aeration quantity, also promptly grasp the bearing capacity that is inflated object, people adopt special barometer measurement to be inflated the interior air pressure of object usually for this reason.Because the special-purpose barometer structure of this class is comparatively complicated, user cost is higher, thus for some inflatable toys and some common inflatable objects, then often comparatively random, thus usually cause inflatable objects owing to excessive damage of inflation.
The purpose of this utility model just is to provide a kind of safe supplemental inflatable device with pressure limiting function, to pass through its simple and practical pressure limiting safeguard construction, make it when not influencing normal gas replenishment process, have advantages such as the stable and wide accommodation of simple in structure, safe and reliable, inner gas pressure.
The purpose of this utility model realizes in the following manner: a kind of safe supplemental inflatable device with pressure limiting function, it is characterized in that said apparatus mainly is made up of three-way pipe and pressure limiting spring, the person in charge's one end of above-mentioned three-way pipe is connected with the gaseous core of band sealant beads by flexible rubber hose, the other end is a charging air inlet, envelope air valve in the form of piston is set in the side pipe of three-way pipe, at the envelope air valve and be fixed between the spring plug of side pipe end and be provided with the pressure limiting spring, and on the tube wall of side pipe, have excessive gas port.
Adopt a kind of safe supplemental inflatable device of the present utility model with pressure limiting function, owing to adopted simple and practical pressure limiting safeguard construction, make it when not influencing normal gas replenishment process, have advantages such as the stable and wide accommodation of simple in structure, safe and reliable, inner gas pressure, can control and guarantee the stable gas pressure in the container very effectively, be a kind of small-sized supplemental inflatable device that integrates novelty, reliability and Security.
Description of drawings:
Accompanying drawing is a kind of example structure schematic representation of the present utility model.
Wherein: the 1-gaseous core, the 2-sealant beads, the 3-flexible rubber hose, the 4-three-way pipe, 5-seals air valve, 6-screw, 7-charging air inlet, 8-rach slot, 9-spring plug, 10-pressure limiting spring, 11-tooth bar, 12-gear, 15-pointer, the 14-gas port that overflows, 15-suction port.
Below in conjunction with accompanying drawing the utility model is advanced to describe in detail.
As shown in the figure, a kind of safe supplemental inflatable device of the present utility model with pressure limiting function, it is characterized in that this device mainly is made up of three-way pipe (4) and pressure limiting spring (10), the person in charge's one end of above-mentioned three-way pipe (4) is connected with the gaseous core (1) of band sealant beads (2) by flexible rubber hose (3), the other end is charging air inlet (7), envelope air valve in the form of piston (5) is set in the side pipe of three-way pipe, at envelope air valve (5) and be fixed between the spring plug (9) of side pipe end and be provided with pressure limiting spring (10), and on the tube wall of side pipe, have excessive gas port (14).In order to understand inflated condition intuitively, device has tooth bar (11) on the sidewall of above-mentioned envelope air valve (5), and this tooth bar passes the rach slot (8) on the side pipe wall, be fixed on dial plate on and match with the relatively-stationary gear of pointer (13) (12).By regulating the elastic force of pressure limiting spring, can change its voltage limiting value.
Its working principle is as follows:
The seal container suction port that is inflated is connected charging air inlet, locate to charge into gas at suction port (15), gas promotes sealant beads and enters into three-way pipe by gaseous core, and injects seal container.Along with the continuous increase of gas flow, the intraluminal gas atmosphere of seal container and three-way pipe acts on the envelope air valve, make pre-designed elastic force spring constantly compress, and promote tooth bar and move, from and driven gear and pointer rotate.When the envelope air valve just moved to the excessive gas port of three-way pipe, the gas in the three-way pipe overflowed in a large number to the external world, and no longer to the container inflation, at this moment, pointer will refer to that in the MAX position air pressure in the container also will remain unchanged.
So adopt this auxiliary device that seal container is inflated,,, all can play and protect the pressure limiting effect safely and effectively to container as long as the relation of the elastic force of voltage limiting value and spring is reasonable in design regardless of its form.
