Background technique:
Under the existing technology condition; The valve of beverage-making machine adopts solenoid valve mostly; This solenoid valve comprises valve seat, electromagnetic valve core and the intake tunnel that is interconnected, valve rod installation channel and exhalant canal, and said electromagnetic valve core is made up of valve rod, spool, spring, magnetic conduction iron plate and electromagnetic coil, and exhalant canal and valve rod installation channel are on same straight line; The top of valve rod installation channel seals, and intake tunnel communicates with the valve rod installation channel.Valve seat is positioned at the joint of exhalant canal and valve rod installation channel; Two equipment are separated; Vertical and the valve seat of valve rod is installed in the valve rod installation channel; The bottom of valve rod is equipped with a spool, and first end of valve rod is equipped with a magnetic conduction iron plate valve rod has been divided into two halves section up and down, and a spring is installed on the upper semisection of magnetic conduction iron plate.Electromagnetic coil is installed in the top of valve rod installation channel.Normal state, under acting force of the spring, valve rod is to moving away from the electromagnetic coil direction, and spool drops on the valve seat, has blocked valve seat, and solenoid valve is closed condition; After to the electromagnetic coil energising, under magnetic force, magnetic conduction iron plate drives spool and moves to the electromagnetic coil direction, and spool breaks away from valve seat, and valve is opening state.
There are following three open defects in this solenoid valve:
1. electromagnetic valve core is positioned at the valve rod installation channel, and in use, the liquid of this passage of process contacts with electromagnetic valve core, meeting oxide etch electromagnetic valve core, and the liquid that flows through the valve rod installation channel simultaneously also can be contaminated;
2. when the fluid viscosity that flows through this valve was big, the electromagnetic valve core of normal power is the Push And Release of control valve accurately, and powerful electromagnetic valve core cost is higher and take up room greatlyyer, uses extremely inconvenience;
3. each with after, the outflow opening of valve has outside liquid residue is exposed to, and is unhygienic.
Summary of the invention:
In order to overcome the defective of existing technology, the present invention provides a kind of new solenoid valve, and this solenoid valve is used for controlling the bigger liquid of viscosity specially.This solenoid valve comprises valve seat, electromagnetic valve core and the intake tunnel that is interconnected, valve rod installation channel and exhalant canal; Said electromagnetic valve core is made up of valve rod, spool, spring, magnetic conduction iron plate and electromagnetic coil; The valve rod installation channel is processed by the elasticity soft material; Electromagnetic valve core is vertical external on the valve rod installation channel; With valve rod one basket support is installed at grade on the electromagnetic valve core, the valve rod installation channel is fixed on the support inner roof wall valve seat perpendicular to support, and spool is parallel to valve seat and is connected on the valve rod installation channel.
Adopt this solenoid valve, because of electromagnetic valve core external on the valve rod installation channel, not with passage in liquid contact, can not corrode electromagnetic valve core, thus the liquid in can pollution channels; Spool is through its open and close of valve rod installation channel control of overstocking, the tensile elasticity soft material is made, and because of electromagnetic valve core does not receive the influence of fluid viscosity in the passage, adopts the electromagnetic valve core of general power just passable, provides cost savings and the space.
As further improvement of the present invention, at valve rod installation channel outflow opening be communicated with purified water passage perpendicular with it, the water that the purified water passage flows out can effectively wash valve rod installation channel outflow opening, has guaranteed the health of passage.
As further improvement of the present invention, the cross section of valve rod installation channel is the regular hexagon ring-type, and two elasticity soft materials that cross section is little right angle trigonometry shape have been added on the both sides at its one group of diagonal angle of outer shroud respectively; The limit of triangle hypotenuse and outer shroud is overlapping, and other two groups of diagonal angles are circular-arc, and this shape valve rod installation channel is under the effect of solenoid valve spring pressure; Circular-arc angle can be launched into straight line fully; Other two jiaos can be folded into 0 degree, have no the slit, have guaranteed the leakproofness of valve.
As further improvement of the present invention; There is protrusion strip part perpendicular on the contained side of the adjacent arc round angle of valve rod installation channel outer wall with support; This protrusion strip part central porose, its one of be used for being fixed on intake tunnel on the support inner roof wall valve seat, another hole is connected with spool.
As further improvement of the present invention, valve rod installation channel outflow opening lower half portion links to each other with the outside seal circle through the arc surfaced soft material.The folding that radian through cambered surface is changed to the valve rod installation channel provides the variable space, makes the outflow opening of valve rod installation channel when closure, become a plane, and the water that also helps coming from the purified water channel flow washes the outflow opening of valve rod installation channel.
As further improvement of the present invention, valve seat is a horizontal stripe, and its one side towards the valve rod installation channel is level and smooth plane, has guaranteed the sealing effect of pressing.
As further improvement of the present invention, spool is a horizontal stripe, and its one side towards the valve rod installation channel is level and smooth plane, has guaranteed the sealing effect of pressing.
