Embodiment
Explanation and embodiment are described further to the utility model below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of Medical low-temperature fluid miniature electromagnetic valve, including valve seat 5, valve element 7 and bonnet 6, the bonnet 6
It is provided with coil holder 11, coil holder 11 and is wound with coil 10, valve seat 5 is fixedly connected with bonnet 6 and both of which is docked provided with cavity
Back-moving spring 8 is nested with the accommodating chamber 14 of the accommodating valve element 7 of composition, valve element 7, the cavity interior walls of valve seat 5 are provided with inlet opening 4 and gone out
Provided with the feed pathway 3 being respectively communicated with inlet opening 4 and fluid hole 2 and liquid outlet channel 1 in fluid apertures 2, valve seat 5, the feed liquor leads to
Road 3 is communicated with liquid outlet channel 1 with the external world, it is characterized in that the fluid hole 2 is on the bottom wall of the cavity of valve seat 5, valve element 7 is resetting
The lower elasticity closure fluid hole 2 of the effect of spring 8, coil 10 produces magnetic field after being powered makes valve element 7 move away fluid hole 2, coil 10
Magnetic field disappears after power-off, the elastic recoil closure fluid hole 2 under the effect of back-moving spring 8 of valve element 7.The utility model is by adjusting valve
Core operating position, coordinates valve element and fluid hole, is caused with avoiding valve element and inlet opening cooperation from being influenceed by feed liquor Fluid pressure
Loosen, magnetic valve reliability is greatly improved, be used for a long time all without leakage.In use, inlet opening remains unimpeded, fluid is filled
Can also compress valve element after full accommodating chamber makes it block fluid hole, improves seal during closed electromagnetic valve, only logical in magnetic valve
Electricity produces magnetic field, and fluid hole is opened in valve element movement, and magnetic valve could be opened.
The fluid hole 2 is located at the pocket base wall center of valve seat 5, and valve element 7 can hold directly over fluid hole 2
