Fig. 1 a depicts the conventional piston with shell 11, piston component 12, first seal 13 and second seal 19
Flushing valve 10.In general, piston component 12, first seal 13 and second seal 19 can be carried in shell 11.In addition,
The shape and size of shell 11 can be set to form intake section 10a and exit portion 10b.As previously mentioned, conventional
Piston flushing valve is typically constructed of metal.Specifically, conventional piston flushing valve 10 is made of metal.More specifically, shell 11
It is made of metal.
Piston component 12 may include the first part that can be attached to of nut 14, piston rod 18, first seal 13 with
And the second part that second seal 19 can be attached to.In addition, first seal 13 can be contacted with nut 14.Show at one
In example sexual orientation, as shown in Figure 1, first part can be the low portion of piston component 12, and second part can be work
The upper part of plug assembly 12.
In use, piston flushing valve 10 can be connected to fluid inlet source (not shown) at intake section 10a.Piston punching
Fluid hose (not shown) can be connected further at exit portion 10b by washing valve 10.From fluid inlet source fluid (for example,
Water) fluid hose for being connected to exit portion 10b can be flowed to via piston component 12 from intake section 10a.
Piston component 12 can be activated, to move in shell 11, to prevent or allow fluid from inlet portion
10a is divided to flow to exit portion 10b.For example, piston component 12 can be according to enabling the piston component in shell 11 along vertical
The mode mobile to axis (as shown in arrow 10c) is activated.
Obviously, it is moved in shell 11 with piston component 12, nut 14 may not become in which can avoid as time goes by
Pine.Since nut 14 loosens, first seal 13 (it is contacted with nut 14) may also fluff.When piston flushing valve 10 is using
When middle (that is, during fluid flows to exit portion 10b across piston component 12 from intake section 10a), there may be small for this
Vibration.In addition, since fluid travels across fluid hose, this microvibration produced may be amplified, to generate hammering
Noise.
Fig. 1 b shows the associated various products form (10d, 10e and 10f) of the piston flushing valve 10 with Fig. 1 a.As schemed
Show, product form is integrated design form.
Fig. 2 a shows piston flushing valve 20 according to the one side of the disclosure.Preferably, piston flushing valve 20 is suitable for
Sanitary equipment (not shown).Piston flushing valve 20 can be further adapted for/be suitable for and portable fluid dispensation machines/equipment
(for example, portable coffee machines) are used together.
Piston flushing valve 20 includes shell 21, piston component 22, primary seal 23 and auxiliary sealing member 29.Piston component 22
Including nut 24 and piston rod 28.Preferably, shell 21 is made of plastics.It is highly preferred that shell 21 is made entirely of plastic.
Shell 21, piston component 22, auxiliary sealing member 29, nut 24 and the piston rod 28 of Fig. 2 a can it is certain but not
All aspects are analogous respectively to shell 11, piston component 12, second seal 19, nut 14 and the piston rod 18 of Fig. 1 a.
In this regard, the relevant portion for being previously with regard to the discussion of Fig. 1 a can be applied similarly to Fig. 2 a.In an example
In, as shown in Figure 2 a, the shape and size of shell 21 can be set in the way of so as to loading piston component 22.Another
In a example, piston flushing valve 20 may include being connected to the intake section 20a of fluid inlet source (not shown) and being connected to stream
The exit portion 20b of body pipe (not shown).
It can at least be existed with the conventional piston flushing valve 10 of Fig. 1 a according to the piston flushing valve 20 of embodiment of the present disclosure
It manufactures different on the material of shell 21 (according to fig. 2) and the material of manufacture shell 11 (according to Fig. 1).Specifically, 21 (root of shell
According to Fig. 2) it is made of plastics, and shell 11 (according to Fig. 1) is made of material (that is, metal) besides plastic.
In addition, according to the piston flushing valve 20 of embodiment of the present disclosure can with the conventional piston flushing valve 10 of Fig. 1 a to
It is few different in sealing arrangement structure.This is discussed in further detail below with regard to Fig. 2 b.
Fig. 2 b shows piston flushing valve 20 when in use and may be at open configuration 30a or closed configuration 30b.
In general, piston component 22 can be activated, make it possible to first position in shell 21 and the second position it
Between move.For example, piston component 22 can axis (for example, as shown in arrow 20c of Fig. 2 a) be mobile along longitudinal direction in shell 21,
So that piston flushing valve 20 is in one of open configuration 30a and closed configuration 30b.
The shape and size of shell 21 can be further set such that opening portion 31a can be limited at inlet portion
Divide between 20a and exit portion 20b to allow fluid from intake section 20a when piston flushing valve 20 is in open configuration 30a
Flow to the mode of exit portion 20b (that is, as shown in direction arrow 31b).Opening portion 31a may include that shape and size can quilt
It is set as carrying the edge portions 31c of primary seal 23.In this regard, it is believed that primary seal 23 is by along opening portion
The edge of 31a carries.
Moreover, in open configuration 30a, it will be appreciated that, piston component 22 is mobile far from primary seal 23, to allow
Fluid flows to exit portion 20b from intake section 20a (as shown in direction arrow 31b).On the contrary, in closed configuration 30b, it can
To understand, the adjacent primary seal 23 of piston component 22 with blocking/closing opening portion 31a and prevents fluid from intake section
20a flows to exit portion 20b (as shown in direction arrow 31d).
In this regard, piston component 22 can be activated, so as to adjoining (that is, substantially completely contacting) primary seal
The mode of 23 (that is, closed configuration 30b) or separate primary seal 23 (that is, open configuration 30a) is mobile.
In one embodiment, when being in open configuration 30a, piston component 22 may be located remotely from the shifting of primary seal 23
It is dynamic, so that still having localized contact between piston component 22 and primary seal 23.However, it is possible to understand, this part
Contact does not prevent fluid from flowing to exit portion 20b from intake section 20a.
In another embodiment, when being in open configuration 30a, piston component 22 may be located remotely from the shifting of primary seal 23
It is dynamic, so that not contacted between piston component 22 and primary seal 23.
Therefore, in the context of the exemplary orientation in Fig. 1 a more early discussed, similar to the conventional design of Fig. 1 a
Auxiliary sealing member 29 can be attached to the upper part of piston component 22.However, the wherein first seal 13 with Fig. 1 is attached to
The conventional piston flushing valve 10 of piston component 12 is compared, and primary seal 23 is not attached to piston component 22.On the contrary, primary seal
23 (for example, being made of rubber) are positioned at the base portion (that is, edge portions 31c) of intake section 20a, and effect is when piston group
Part 22, which is moved to close when being limited at the opening portion 31a between intake section 20a and exit portion 20b, makes any fluid
Flowing stops.In other words, primary seal 23 is maintained at fixed position relative to the movement of piston component 22 in shell 21
(that is, primary seal 23 is not moved together with piston component 22 and nut 24).In this regard, it is believed that primary seal 23 is in work
The mobile period of plug assembly 22 and shell 21 are kept fixed relationship.
More specifically, primary seal 23 can fixedly be carried in shell 21.More specifically, primary seal 23 can be with
It is carried in shell 21 in fixed and stable mode, so that primary seal 23 is still in shell although piston component 22 is mobile
It is held in place substantially in body 21.Therefore, in the mobile period of piston component 22, primary seal 23 is considered and its surrounding objects
(that is, in shell 21) is kept fixed relationship.
In this regard, it will be appreciated that, it is associated according to the piston flushing valve 20 with Fig. 2 of embodiment of the present disclosure
Sealing arrangement structure can be different from the sealing arrangement structure of conventional piston flushing valve 10.
Clearly as primary seal 23 substantially reduces a possibility that fluffing (that is, since piston component 22 is mobile), produce
A possibility that stating microvibration and/or hammering noise before death will significantly reduce.Primary seal 23 can be by propylene diene
Monomer (EPDM) rubber or nitrile rubber (NBR) are made.
In addition, as mentioned above, piston flushing valve 20 (i.e. Fig. 2) can be with conventional piston flushing valve 10 (i.e. Fig. 1 a) no
Together, this is because the shell 21 of piston flushing valve 20 is made of plastics (it is highly preferred that being made entirely of plastic), and conventional piston
The shell 11 of flushing valve 10 is made of metal.Obviously, as previously discussed, etching problem associated with conventional piston flushing valve
It can be greatly reduced.
According to embodiment of the present disclosure, nut 24 may include the movement for guiding piston assembly 22 in shell 21
Multiple flanks 25 of (that is, movement between open configuration 30a and closed configuration 30b).In addition, piston component 22 can be wrapped also
Plastic filter (strainer) 26 is included, which, which plays, prevents unwanted material (such as grains of sand) from entering piston flushing valve
The effect of 20 filter device.Plastic filter 26 can (for example) be positioned/be placed in the second part (example of piston component 12
Such as, upper part) at.
