Description
Technical field
The utility model relates to the pneumatic element technical field, particularly a kind of pneumatic safty device.
Background technique
Along with the continuous development of industry, pneumatic element pneumatic tool is in other words used more and more widely.The air tool in other words tracheae of existing pneumatic element generally is formed by connecting by hard tube and flexible pipe, and hard tube is mainly used in the connection source of the gas, and flexible pipe is mainly used in connection pneumatic operation spare, with extended length and bending, is convenient to specific operation.Existing pneumatic element in other words pneumatic tool the operation process in; Especially when installation and maintenance; Have bigger potential safety hazard, its reason is when pneumatic operation spare or flexible pipe generation breakage or gas leakage, will form phenomenons such as the acute sharp swing of high-pressure jet or flexible pipe; The acute sharp swing of this high-pressure jet or flexible pipe is as easy as rolling off a log to damage operator, and potential safety hazard is big.Be necessary the employing measure, prevent that as far as possible this phenomenon from taking place, and eliminates safe hidden trouble.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, and a kind of simple and compact for structure, reliable pneumatic safty device of handling safety are provided.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The described a kind of pneumatic safty device of the utility model comprise valve body and end cap, form suction port in said valve body one end; Form receiving cavity in the other end; Suction port is communicated with receiving cavity, forms the air outlet in the said end cap, and said end cap one end cooperates to be located in the receiving cavity; Be provided with by Sealing between said suction port and the air outlet, end the diameter of the diameter of Sealing, be provided with vent by the Sealing neutral position less than receiving cavity; Said ending between Sealing and the end cap is provided with spring.
Preferably, said end cap outer wall moulding one stepped part, said spring is located between Sealing and stepped part.
Preferably, saidly be provided with sealing gasket near the side of air outlet one side by Sealing.
Preferably, said suction port outer end inner wall is provided with connecting thread.
Preferably, said air outlet outer end inner wall is provided with connecting thread.
After adopting said structure; The utility model beneficial effect is: the utility model is connected between hard tube and the flexible pipe, like flexible pipe and the pneumatic operation spare that is connected with flexible pipe damaged or gas leak phenomenon takes place, can move right under the pressure high gas flow in suction port by Sealing; Thereby sealing air outlet; Thereby effectively avoid the acute sharp swing of high-pressure jet or flexible pipe, overcome the technical problem that exists in the existing technology, greatly improved safety coefficient.The utility model is simple in structure, and is easy to operate, and fabricating cost is low.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Among the figure:
1, end cap; 2, spring; 3, by Sealing; 4, valve body;
5, connecting thread; 6, suction port; 7, vent; 8, sealing gasket;
9, receiving cavity; 10, stepped part; 11, air outlet.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the described a kind of pneumatic safty device of the utility model comprise valve body 4, and end cap 1 and by Sealing 3 also is a valve body 4, end cap 1 and the agent structure that constitutes the utility model by Sealing 3.Said valve body 4, end cap 1 can adopt metal or hard plastics to process, and process by the then general employing soft plastic of Sealing 3 material, are beneficial to realize sealing effect.
Wherein, form suction port 6 in said valve body 4 one ends, suction port 6 outer end inner walls are provided with connecting thread 5, are used for connecting the hard tube of pneumatic element or pneumatic tool; Form receiving cavity 9 in said valve body 4 the other ends, suction port 6 is communicated with receiving cavity 9.
Be provided with by Sealing 3 between said suction port 6 and the air outlet 11, end the diameter of the diameter of Sealing 3, forming the gas communication passages by Sealing 3 peripheries less than receiving cavity 9; Saidly be provided with vent 7 by Sealing 3 neutral positions, be provided with sealing gasket 8 near the side of air outlet 11 1 sides, help improving sealing effect by Sealing 3.
Said ending between Sealing 3 and the end cap 1 is provided with spring 2, in particular, said end cap 1 outer wall moulding one stepped part 10, said spring 2 is located between Sealing 3 and stepped part 10.
Working principle: the utility model suction port 6 connects the pneumatic elements hard tube in the pneumatic tool in other words, and air outlet 11 connects the pneumatic elements flexible pipe in the pneumatic tool in other words.Under the normal working, gas gets into from suction port 6, through the gas communication passage by Sealing 3 peripheries; After air outlet 11 flow out; At this moment, the air pressure by Sealing 3 both sides equates, under the effect of spring 2, is in the high order end of receiving cavity 9 by Sealing 3.The pneumatic operation spare that connects of flexible pipe in the pneumatic tool and flexible pipe is damaged or when leaking gas in other words when pneumatic element, is broken by the pressure balance of Sealing 3 both sides, and wherein the pressure of suction port 6 one sides is greater than the pressure of air outlet 11 1 sides; Move right under gas pressure by Sealing 3; Sealing air outlet 11, spring 2 is in compressive state, at this moment; Gas is through vent 7 circulations; Gas pressure is very little in the flexible pipe, has effectively avoided swashing because of flexible pipe and pneumatic operation spare is damaged or gas leakage is produced high-pressure jet or flexible pipe are acute phenomenons such as swing, and safety coefficient greatly improves.After flexible pipe and the eliminating of pneumatic operation spare fault; After vent 7 circulates a period of times; Pressure by Sealing 3 both sides will reach balance once more; End Sealing 3 is returned to receiving cavity 9 under the effect of spring 2 high order end, suction port 6 is communicated with through the gas communication passages by Sealing 3 peripheries with air outlet 11 once more, the utility model recovery proper functioning.
The utility model is simple in structure, and is easy to operate, and fabricating cost is low, but greatly improved the safety coefficient of pneumatic element.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
