Abstract

The utility model discloses an electromagnetic triple valve which can be used for a plurality of liquid media of low causticity in an automatic weighting and controlling system to realize a liquid automatic weighting work, in particular is used to weigh the output of the well. Because a usual faucet-typed structure is replaced by a valve disc and clack seat structure, the straight-going is realized and the complicated structure where the electromagnetic triple valve changes the straight-going into a rotation is released, having the advantages of simple structure, flexible actions, fast switching, good sealing properties, low power consumption and being easy to prevent the explosion.

Description

A kind of three-way solenoid valve

The utility model belongs to the solenoid valve three-way valve, especially for the three-way solenoid valve of liquid meter.

After oil field and some chemical enterprises usually will be squeezed into measuring tank to some liquid by a flow direction of three-way valve with it and measure, again it is flow in other pipeline or the container through another flow direction by original valve body and go, the structure of three-way solenoid valve commonly used is the cock that a T type hole is arranged in the valve body, straight line motion by the moving magnetic core of electromagnet when need change liquid flow direction drives cock rotation 90 degree by transmission device, though this three-way valve can change the flow direction of liquid in valve according to the break-make of electric current, but owing to need transmission device that the straight line motion of electromagnet is become rotatablely moving of cock, structure is complicated, need the power of electromagnet bigger, and be difficult for carrying out explosion-proof protection.

The purpose of this utility model provides a kind of technological scheme of directly utilizing the electromagnet straight line motion to change liquid three-way solenoid valve of flow direction in three-way valve.

The utility model is realized by following scheme: left tube chamber its internal orifice downside that is inclined upwardly exceeds the collar extension center line in valve body, downward-sloping its internal orifice upside of right tube chamber is lower than the collar extension center line, middle upper valve base with holes is housed between left tube chamber internal orifice lower wall and right tube chamber internal orifice upper side wall, lower valve base with holes in the middle of suitable for reading being equipped with of following tube chamber, the last valve disc, time valve disc that are fixed on the valve rod assembly are installed between upper valve base and the lower valve base and also can move up and down, and fixedly connected with moving iron core in the valve rod assembly upper end.

At non-power status, under the effect of valve rod assembly gravity and return spring, be connected in the following valve disc on the valve rod assembly and be contained in down tube chamber lower valve base suitable for reading and fit tightly, thereby make right tube chamber of valve body and following tube chamber sealing, liquid medium is gone into the container that is connected with right tube chamber by valve body left side tube chamber through the upper valve base orifice flow; In "on" position, because the moving iron core drive of the effect of electromagnetism valve rod assembly upwards promotes valve disc and lower valve base is left, last valve disc and upper valve base are fitted left tube chamber and right tube chamber are closed, and liquid medium is flowed out by following tube chamber mouth through the lower valve base hole from the container that is connected with right tube chamber.Whether energising can be controlled by the sensor that is installed in the container that is connected with right tube chamber.

The utility model has adopted the flow direction of direct dynamic structure controlling liquid medium, has simple in structure, advantages such as keying is rapid, good airproof performance, power saving, long service life.

Further the utility model is done an explanation below in conjunction with drawings and Examples.

Accompanying drawing is a generalized section of the present utility model.

Among the figure: 1. descend tube chamber, 2. valve body, 3. lower valve base, 4. descend valve disc, 5. right tube chamber, 6. go up valve disc, 7. upper valve base, 8. left tube chamber, 9. valve rod assembly, 10. valve body upper end cap, 11. moving iron cores, 12. non-magnetic tube assemblies, 13. static iron cores, 14. return springs, 15. Electrical heads.

As shown in the figure, by valve body 2, valve seat 3,7, valve disc 4,6, valve rod assembly 9, moving iron core 11, non-magnetic tube assembly 12, static iron core 13, return spring 14, the three-way solenoid valve that Electrical heads 15 is formed, left side tube chamber 8 its internal orifice downside that is inclined upwardly exceeds the collar extension center line, right tube chamber 5 downward-sloping its internal orifice upsides are lower than the collar extension center line, middle upper valve base 7 with holes is housed between left tube chamber internal orifice lower wall and right tube chamber internal orifice upper side wall, lower valve base 3 with holes in the middle of suitable for reading being equipped with of following tube chamber 1, be fixed on last valve disc 6 on the valve rod assembly 9 and following valve disc 4 and be installed between the lower valve base and can move up and down, valve rod assembly is fixedlyed connected with moving iron core 11.
