The pressure release valve device of the coffee machine can automatically eliminate residual pressure in the coffee machine after boiling coffee, thereby not needing any other extra operation of users, and saving the cost of the coffee machine.
Description
(1) technical field
The utility model relates to relief valve, specifically is meant the relief valve device of coffee machine.
(2) background technology
Usually, coffee machine all needs to carry out pressure release after having boiled coffee, mainly is to eliminate to have boiled the residual pressure in the coffee machine after the coffee.Its basic principle is that the pipeline that will go out coffee switches, and delivery port is transformed into pressure relief opening from the outlet of well-done liquid coffee.Traditional way is to realize transfer process by a magnetic valve.Adopt the magnetic valve pressure release, the use cost height can't reach low-cost.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of novel relief valve device, and use cost is low, and result of use is good.
For this reason, the utility model is taked following technical scheme:
A kind of relief valve device of coffee machine, include valve body, valve gap, described valve body is provided with and the extraneous delivery port that communicates, pressure relief opening, described valve gap is provided with water inlet, described valve body and valve gap inside are provided with and water inlet, the "T"-shaped pipeline that delivery port and pressure relief opening are communicated with, in described valve body, be provided with water outlet valve pocket with pipeline connection, be provided with the water outlet spool that is tightly connected with it in the described water outlet valve pocket, the outer face of described axially displaceable water outlet spool offsets with valve gap inner face alternative and cooperates, and is provided with return spring between described outlet valve in-core end face and the valve interior wall; Described water outlet spool chamber is a hollow structure, in be provided with seal head, hollow screw, described seal head is inner small and outside big stepped, offset with the cascaded surface inwall of water outlet spool and to cooperate, the smaller portions of sealing head are arranged with the back pressure spring, described screw is threaded with outlet valve in-core wall, and the elongated end of back pressure spring runs through screw and offsets with the screw inwall; The valve body of adjacent delivery port one side of described pressure relief opening is a hierarchic structure, and described water outlet spool is provided with the cascaded surface that matches, and described pressure relief opening is positioned at the trip segment of water outlet spool.
Also be provided with the safe valve pocket that communicates with pipeline in the described valve body, the upper surface of described safe valve pocket is over against the trip segment of answering the water outlet spool, be provided with safe ball, safety spring in the described safe valve pocket, the inner face of safe ball one end and safe valve pocket offsets, the other end and safety spring offset, and described safety spring elongated end and safe valve pocket are fixed.
Operation principle of the present utility model is: under normal conditions, under the return spring effect, the water outlet spool holds out against valve gap, and delivery port is blocked, and pressure relief opening is in open mode; When the pump work of coffee machine, promote water outlet spool and seal head, the water outlet spool has been blocked pressure relief opening, because the elastic force of back pressure spring is greater than return spring, the initial sealing head is blocked outlet pipeline, after pressure relief opening is blocked, pressure in the water outlet valve pocket rises rapidly, elastic force that could the back pressure spring promotes seal head, separates with the water outlet spool end, and water can flow out from delivery port; After having boiled coffee, the pressure in the coffee machine diminishes, under the effect of back pressure spring, and seal head and water outlet spool synchronous reset, delivery port is blocked, and pressure relief opening is opened, and the residual pressure in the coffee machine is got rid of elimination by pressure relief opening; When residual pressure is big, the impact safety ball, the part residual pressure is discharged by safe valve pocket, effectively fast release pressure.
The utility model has the advantages that: 1, can eliminate automatically and boil the residual pressure in the coffee machine after the coffee, must the user not do any extra operation, save the cost of coffee machine; 2, increased the safety valve cavity configuration, when residual pressure is big, the impact safety ball, the part residual pressure is discharged by safe valve pocket, has improved the security performance of coffee machine; 3, easy to use, simple in structure.
