Description
Technical field
The container that the utility model relates to one-way valve and uses this one-way valve, especially high-pressure closed vessel.Described high-pressure closed vessel for example is with elastic gel or high viscosity hydraulic oil Equilibrator, buffer, vibration damper, the oil hydraulic cylinder as resisting medium.
Background technique
High-pressure closed vessel can use one-way valve to seal, and this encapsulating method is a key technology in high-pressure closed vessel field.In recent years,, be widely used in gradually in the industrial fields such as metallurgy, harbour, boats and ships, communications and transportation as development constantly such as the Equilibrator of resisting medium, buffer, vibration damper, oil hydraulic cylinders with elastic gel or high viscosity hydraulic oil.One-way valve commonly used is set up higher initial pressure and is kept initial pressure in these high-pressure closed vessels; The structure of one-way valve, performance, assembly technology etc. become the key factor that influences quality of product, manufacturing efficiency, life-span.
The inside of high-pressure closed vessel product has high-pressure sealed space.After the product assembling is finished, can in container, add inner filled media (for example elastic gel) by one-way valve, set up the initial pressure that needs, to satisfy performance requirement.
One-way valve in the market mostly is the structural type that spool adds sealing, has shortcomings such as many, withstand voltage low, the easy leakages of complex structure, sealing part.Some one-way valve adopts bonding way or outside screw-in mode.Wherein, bonding way exists that set time is long, quality is unstable, to problems such as environmental requirement harshnesses, influenced quality of product and manufacturing efficiency; Outside screw-in mode is because by threads carry, so double thread requires height, there is potential safety hazard in all high pressure simultaneously.
Fig. 1 shows the structural type of a kind of existing seal container that adopts one-way valve 30, and this container has adopted the adhering and sealing mode.Particularly, one-way valve 30 and cylinder body 10 usefulness binders are carried out adhesion, prevent the external leakage of elastic gel 20 from one-way valve 30 at the screw thread S of one-way valve 30 and adjacent with it A part.
Fig. 2 show adopt one-way valve 30 ' the structural type of the existing seal container of another kind.Particularly, one-way valve 30 ' from cylinder body 10 ' the outside along direction left screw in cylinder body 10 ', and cylinder body 10 ' and one-way valve 30 ' between the B place static seal (for example packing ring) of packing into, to prevent that elastic gel 20 is from one-way valve 30 ' leakage.
For above-mentioned two kinds of structures, adhering and sealing mode soundness shown in Figure 1 is good, and is safer reliable.It is high that but this structural type requires the joint clean degree; Simultaneously, bonding link needs longer set time, technique for sticking complexity; And this structure is not easy dismounting, in case generation is leaked then can only or be destroyed this structure and handle by high temperature.Static seal mode shown in Figure 2 is convenient to installing/dismounting.But in this structure, the screw thread of one-way valve directly bears the high pressure effect, double thread requirement of strength height; Simultaneously, the groove dimensions of B place installation Sealing is less, and the difficulty that machining reaches precision prescribed is bigger, if concentricity or degree of finish are not enough, this structure just can only be scrapped.
The model utility content
The utility model provides a kind of one-way valve, is used to be installed to the cylinder body of container, and described cylinder body can hold filled media in inside.Described one-way valve comprises valve body and Sealing.Wherein, valve body has outer surface around axis, along first end of described axis and second end and cavity that described first end and described second end are communicated with, described cavity is in the internal communication of described first end place and described cylinder body, described cavity has neck, and described neck edge is from the first direction constriction of described first end towards described second end.Sealing is arranged in described cavity, and can cooperate with described neck when being subjected to described filled media along power that described first direction applies, spills described valve body to prevent described filled media from described second end.Described valve body has the shaft shoulder around described axis, and the diameter of the described shaft shoulder is greater than the diameter of described outer surface at the described second end place.
The utility model also provides a kind of container, and this container comprises cylinder body and one-way valve, and cylinder body can hold filled media and have in inside makes its first opening inner and external communications.Wherein, described one-way valve comprises valve body and Sealing.Valve body has outer surface around axis, along first end of described axis and second end and cavity that described first end and described second end are communicated with, described cavity is in the internal communication of described first end place and described cylinder body, described cavity has neck, and described neck edge is from the first direction constriction of described first end towards described second end.Sealing is arranged in described cavity, and can cooperate with described neck when being subjected to described filled media along power that described first direction applies, spills described valve body to prevent described filled media from described second end.Described valve body has the shaft shoulder around described axis, and the diameter of the described shaft shoulder is greater than the diameter of described outer surface at the described second end place.
According to the utility model, container has been avoided the employing bonding way, therefore removes and installs all very convenient.Simultaneously, according to preferred embodiment of the present utility model, because the effect of the shaft shoulder, the screw thread of outer surface does not bear the high pressure effect of the filled media of (or not exclusively bearing) cylinder interior, and is therefore safe and reliable.And, therefore enough spaces being arranged owing to have the groove that is used to install static seal between the shaft shoulder and second shaft shoulder, machining reaches precision prescribed easily.
