Description
Technical field
The present invention relates to valve class technical field, the two-position two-way solenoid valve of more particularly to a kind of install convenient and its work side
Method.
Background technology
Valve class product is widely used in the fluid control of each technical field, and two-position two-way solenoid valve is one kind therein,
It is well known and common.Common two-position two-way solenoid valve on the market at present, structure generally include valve body, on valve body point
Not She You air inlet and gas outlet, the gas port connected always with gas outlet is equipped in valve body, is additionally provided with to control on valve body
The first guide assembly of access on or off between gas port and air inlet processed.When guide assembly is powered in the ban, first guide assembly moves
Iron core is by the effect of magnetic attraction and far from gas port so that the input terminal of gas port is switched on, air inlet, gas port and outlet
Gas passage is formed between mouthful, the gas in air inlet flow to gas outlet at this time；When guide assembly powers off in the ban, dynamic iron core is in dynamic iron
It is resetted under the action of core spring and in sealing contact with gas port so that the input terminal of gas port is blocked, at this time in air inlet
Gas can not flow to gas outlet.
However, existing two-position two-way solenoid valve is because structure setting is unreasonable, usually with following defect：First, due to
Air inlet is connected with air source, and when the air pressure of air source is unstable, the air pressure for be easy to causeing gas outlet is fluctuated, especially
When the pressure of air inlet is higher than the nominal pressure of gas equipment, the stability of gas equipment working performance can be seriously affected, very
To gas equipment is caused to damage, in order to solve the problems, such as this, compared with frequently with way be between air source and air inlet set one
Pressure maintaining valve, but can not only so that pipeline structure setting is complicated, but also increases use cost using pressure maintaining valve；Second, valve body
Mounting connection structure setting between the casing of first guide assembly is unreasonable, specifically, valve body and casing generally use at present
Two kinds of connection structures, a kind of is by setting the valve plate being fixedly connected with the valve body, the bottom end of casing being pressed on valve plate and valve body
Between, the defects of this mounting means, is mounting structure complexity, causes to install relatively complicated inconvenience；Another kind is in casing
Bottom end is extended male threaded joint, and casing is fixedly connected with the valve body by male threaded joint, this mounting means it is excellent
Point be it is simple in structure, it is quick for installation, but have the disadvantage that, since air pressure is higher in the valve chamber of valve body, in the length of high pressure gas
Phase vibration, impact when, the screw connection structure between casing and valve body is susceptible to the trend of loosening, cause casing with
Connection is not sufficiently stable between valve body, influences the service life of valve.
