Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, top, bottom " is usually
Be for direction shown in the drawings either for it is vertical, vertically or on gravity direction for each component mutual alignment
Relationship description word.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The utility model provides a kind of outer cover 1 of pressure valve, as shown in Figure 1, the periphery wall hoop of outer cover has snap ring and shape
At the protrusion buckle 12 for having preventing snap ring to loosen, the circumferential two sides of protrusion buckle 12 are respectively equipped with from the bottom of outer cover prolongs axially upward
The cut groove 13 stretched forms the periphery wall elastic piece 11 with protrusion buckle 12 between two cut grooves 13.
During the hoops such as snap ring part is sheathed with annular slot from the top surface of outer cover with firm assembly, snap ring can be by
Slide downwards to mechanical device or the external forces such as artificial and first buckles 12 close contacts with the protrusion on periphery wall elastic piece 11.
At this point, periphery wall elastic piece 11 is radially-inwardly compressed due to itself having certain elastic deformation ability so that protrusion buckle
12 realize evacuation movement, so that it is guaranteed that snap ring can be easily slid on annular slot glibly to complete tooling, avoid protrusion
The abrasion or deformation of buckle 12 and lose the function of limited location snap ring, extend the service life of outer cover.And in the process for removing snap ring
In, similarly periphery wall elastic piece 11 can be radially-inwardly compressed so that 12 evacuation snap rings of protrusion buckle, the maintenance of outer cover or more
It is low to change difficulty.
Preferably, the periphery wall of protrusion buckle 12, periphery wall elastic piece 11 and outer cover is integrally formed.For example, can be used one
The production technologies such as body injection molding.At this point, above-mentioned three has the intensity at position interconnected and toughness higher, it is ensured that outer
It will not be deformed by over-voltage during covering on the hoops parts such as suit snap ring, and further increase its use intensity.
Specifically, the circumferential distance of cut groove 13 and protrusion buckle 12 is not more than 5mm.The circumferential distance is excessive will lead to it is convex
The lateral dimension for playing buckle 12 is too small, to reduce its limit range to snap ring, is unfavorable between snap ring and annular slot
Secured assembly.Therefore, which is arranged relatively reasonable in 5mm or less.For example, may be configured as 2.5mm, 3mm or
3.5mm waiting.
Further, the width of cut groove 13 can be 1mm~3mm.The width of cut groove 13 crosses senior general and is unfavorable for outer cover on
The periphery wall elastic piece 11 with favorable elasticity is formed between two cut grooves 13, it is difficult to ensure snap ring is easily set in glibly
On annular slot.Therefore, which is arranged in above-mentioned size range relatively reasonable.For example, may be configured as 1.5mm, 2mm or
2.5mm waiting.
Specifically, as shown in figure 3, the internal perisporium of outer cover is formed with internal perisporium back-off portion 14.It uses in the internal perisporium back-off portion 14
Limit is mutually buckled in the valve seat of the pressure valve with outer cover institute the cover, the assembly improved between the valve seat of pressure valve and outer cover is stablized
Property.
Preferably, the top surface of outer cover can be formed with central recess 15, and central recess 15 can be formed with center through hole.It is pressing
After power valve completes whole assembly, spool can be pierced by the center through hole of central recess 15 upwards and be lower than the top surface of outer cover.
As it can be seen that during outer cover the cover is assembled to valve seat, mechanical device or while manually applying pressure to the top surface of outer cover, need not
Spool is deliberately avoided, the top surface of outer cover has the force-applied region area bigger compared with the prior art, efficiently solves pressure valve
The technical problems such as outer cover assembly difficulty and installation are not in place.
In addition, the utility model additionally provides a kind of pressure valve 2, as shown in Figures 2 and 3, which includes valve seat
21, snap ring 24 and the outer cover of above-mentioned pressure valve 1, simultaneously the cover valve seat 21, outer cover 1 are formed with radially outer bottom to the connection of outer cover 1
Along flange, 24 hoop of snap ring on the periphery wall of outer cover 1 and be limited in protrusion buckle 12 and bottom between flange.
Preferably, the internal perisporium of the outer cover of the pressure valve 2 can be formed with internal perisporium back-off portion 14, the periphery wall shape of valve seat 21
At there is valve seat limiting section 25, internal perisporium back-off portion 14 engages with valve seat limiting section 25.The snap-in structure keeps valve seat 21 and outer cover real
Now mutually limit, it is ensured that firmly installing between valve seat and outer cover.
Further, the top surface of outer cover can be formed with central recess 15, and central recess 15 is formed with center through hole, pressure
Valve 2 includes spool 22, and the top of spool 22 is pierced by axially upwards and is lower than the top surface of outer cover from the center through hole of outer cover.This is outer
The top surface of cover have the force-applied region area bigger compared with the prior art, efficiently solve pressure valve outer cover assembly difficulty and
The technical problems such as not in place are installed.
Specifically, pressure valve 2 further includes the compressed spring 23 being sheathed on spool 22, and valve seat 21 is equipped with valve port and Valve mouth cover
26, the bottom end connection Valve mouth cover 26 and top elasticity of compressed spring 23 press on the roof of outer cover.
In addition, the utility model additionally provides a kind of pressure means, which includes electric pressure rice cooker, pressure electricity
Rice cooker includes above-mentioned pressure valve 2.By using the pressure valve 2 of the utility model, the production efficiency and use of the pressure means
Reliability is effectively improved.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above
Detail in above embodiment can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of simple variants, these simple variants belong to the protection scope of the utility model.
It is further to note that specific technical features described in the above specific embodiments, in not lance
It in the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the utility model is to each
No further explanation will be given for the possible combination of kind.
In addition, any combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed
The thought for carrying on the back the utility model, equally should be considered as content disclosed in the utility model.
