Abstract
The invention discloses a back pressure valve for a coffee maker. The back pressure valve comprises a valve body, a valve bonnet, a valve core component and a back pressure spring, wherein the valve bonnet is arranged on the valve body, a circulating pipeline is arranged inside the valve body, one end of the spool component is arranged in the valve body, the valve core component enables the pipeline in the valve body to form a water inlet end and a water outlet end which are not communicated, a guide hole for guiding is arranged in the valve bonnet, the other end of the spool component is arranged in the guide hole, and the spool component is in elastic connection with the valve bonnet through the back pressure spring. With the adoption of the technical scheme, the back pressure valve for the coffee maker has the beneficial effects that by the aid of the back pressure valve for the coffee maker containing a guide shaft and a double-guide part, back pressure in the pipeline can be stable, and pressure of a control system and flow of water in the system can be controlled accurately.
Description
?
Technical field
The present invention relates to a kind of back pressure apparatus of liquid line, be specifically related to a kind of counterbalance valve for coffee machine.
Background technology
In the pipe-line system of general coffee machine inside, all contain back pressure apparatus, its effect is: make system pressure reach design point, yet thereby control the flow of water in whole pipe-line system., impact due to its back pressure apparatus internal structure, pressure in pipeline is very unstable, can not reach the flow of water in accurate control system pressure and system.
?
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of counterbalance valve for coffee machine, can make the pressure stability of back pressure in pipeline, accurately the flow of water in control system pressure and system.
For achieving the above object, technical scheme of the present invention is as follows: a kind of counterbalance valve for coffee machine, comprise valve body, valve gap, core assembly and back pressure spring, described valve gap is arranged on described valve body, described valve inner is provided with the pipeline of circulation, one end of described core assembly is arranged in described valve body, and described core assembly forms disconnected water inlet end and water side by the pipeline in described valve body; For the pilot hole of guide effect, the other end of described core assembly is arranged in described pilot hole in described valve gap, and by back pressure spring, is connected between described core assembly and described valve gap.
Preferably, described core assembly comprises the axis of guide, back pressure cap and guide holder, and the described axis of guide is arranged in described guide holder, and described back pressure cap is arranged on described axis of guide one end.
Preferably, described back pressure cap is conical.
Preferably, also comprise the sealing ring for sealing, described sealing ring is arranged between described core assembly and described valve body.
Adopt the beneficial effect of the technical program to be: by setting, to contain the axis of guide and dual guide, can make the pressure stability of back pressure in pipeline, accurately the flow of water in control system pressure and system.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in embodiment of the present invention technology, to the accompanying drawing of required use in embodiment technical description be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is original state structural representation of the present invention.
Fig. 2 is working state structure schematic diagram of the present invention.
Numeral and the represented corresponding component title of letter in figure:
1. valve body 2. axis of guide 3. valve gap 4. back pressure spring 5. guide holder 6. sealing ring 7. back pressure cap 8. water inlet end 9. water side 10. pilot holes.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of counterbalance valve for coffee machine of the present invention, comprise valve body 1, valve gap 3, core assembly and back pressure spring 4, valve gap 3 is arranged on valve body 1, valve body 1 inside is provided with the pipeline of circulation, one end of core assembly is arranged in valve body 1, and core assembly forms disconnected water inlet end 8 and water side 9 by the pipeline in valve body 1; In valve gap 3, for the pilot hole 10 of guide effect, the other end of core assembly is arranged in pilot hole 10, and by back pressure spring 4 elasticity, is connected between core assembly and valve gap 3.
Core assembly comprises the axis of guide 2, back pressure cap 7 and guide holder 5, the axis of guide 2 is arranged in guide holder 5, and back pressure cap 7 is arranged on the axis of guide 2 one end, and back pressure cap 7 is conical, also comprise the sealing ring 6 for sealing, sealing ring 6 is arranged between core assembly and valve body 1.
As shown in Figure 1, back pressure cap 7 is connected on the axis of guide 2, and back pressure spring 4 one end act on the axis of guide 2, and the other end acts on valve gap 3.The center of the axis of guide 2 is by the center of valve gap 2 and the center of guide holder 5, and sealing ring 6 seals between the axis of guide 2 and valve body 1.When water enters valve body 1 by water inlet end 8, due to the effect of the axis of guide 2 at back pressure spring 4 elastic force, back pressure cap 7 and valve body 1 sealing.
As shown in Figure 2, along with pressure constantly increases, when being greater than the force value of back pressure spring 4, back pressure cap 7 is backed down, and water flows out from the water side 9 of valve body.In the process of constantly being backed down at back pressure cap 7, due to the guide effect of valve gap 3 with 5 pairs of axis of guides 2 of guide holder, make the axis of guide 2 along move upward along central shaft all the time always, back pressure spring 4 is constantly compressed, until valve inleting water end 8 and water side 9 pressure balances.In the compressed process of back pressure spring 4, compressed along axis direction all the time, thus the stability while having guaranteed each duty.
Adopt the beneficial effect of the technical program to be: by setting, to contain the axis of guide and dual guide, can make the pressure stability of back pressure in pipeline, accurately the flow of water in control system pressure and system.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
