Description

Electromagnetic valve for conveying dangerous chemicals

Technical Field

The utility model belongs to the technical field of the valve, concretely relates to a solenoid valve for hazardous chemicals is carried.

Background

The electromagnetic valve is an industrial device controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator, and is not limited to hydraulic pressure and pneumatic pressure. Used in industrial control systems to regulate the direction, flow, velocity and other parameters of a medium. The solenoid valve can be matched with different circuits to realize expected control, and the control precision and flexibility can be ensured. There are many types of solenoid valves, with different solenoid valves functioning at different locations in the control system, the most common being one-way valves, safety valves, directional control valves, speed control valves, etc.

Patent document No. 201920430128.X discloses a solenoid valve, which changes the position of a chromium-plated iron bead by adopting a magnetic adsorption mode of an electromagnetic coil, so as to realize the opening and closing and opening adjustment of the solenoid valve, but the solenoid valve has the problem that the maximum opening of the solenoid valve is very small, the complete opening of a valve body cannot be realized, so that the solenoid valve cannot adapt to the use requirement of high flow, and the application is greatly limited.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the electromagnetic valve for conveying the dangerous chemicals is convenient to adjust the opening degree and can completely open the valve body.

The technical scheme is as follows: in order to realize the above-mentioned purpose, the utility model provides a solenoid valve for hazardous chemicals is carried, including valve body, guide rail, solenoid and magnetic force piece, be provided with the accuse in the valve body and flow the chamber and cooperate the valve iron plate that flows the intracavity in the accuse, the chamber upwards extends to form and extends the chamber is flowed in the accuse, the valve iron plate is closely laminating the accuse and is flowed the chamber and extend the chamber, solenoid is located and extends chamber outside top department, the magnetic force piece is located and extends the intracavity, solenoid and magnetic force piece are being connected respectively at the both ends of guide rail, the magnetic force piece is used for adsorbing the valve iron plate, the guide rail is used for driving the valve iron plate and reciprocates.

Furthermore, the flow control cavity is of a square structure.

Furthermore, the channel of the flow control cavity is larger than the channel of the valve body, so that the valve iron block can completely close the channel of the valve body.

Further, the guide rail is positioned at the top center of the extension cavity.

Has the advantages that: compared with the prior art, the utility model, through the setting in accuse flow chamber and extension chamber, set solenoid and magnetic force piece to the longitudinal position of valve iron plate for the valve iron plate becomes longitudinal movement and adjusts the aperture, and not only aperture regulation is more convenient, high-efficient, can easily realize arbitrary aperture in addition and adjust, has solved the problem that the aperture adjustable range that originally exists is little, thereby has adapted to the user demand of high flow, and market value obtains obviously promoting.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in fig. 1, the utility model provides a solenoid valve for hazardous chemicals is carried, including valve body 1, guide rail 7, solenoid 6, magnetic block 5 and valve iron plate 4, the chamber 4 is flowed in the accuse that the intermediate part of the passageway in the valve body 1 outwards expands and forms square structure, the passageway that the chamber 4 was flowed in the accuse is greater than the valve body passageway, the top that the chamber 4 was flowed in the accuse continues upwards to extend and forms and extend chamber 3, valve iron plate 4 is closely laminating accuse and is flowed chamber 4 and extend chamber 3, magnetic block 5 is located the top department that extends the intracavity 3 interior valve iron plate 4, guide rail 7 vertically stretches into from the guide rail hole (not shown in the figure) that extends chamber 3's top center department and extends in the chamber 3, magnetic block 5 connects in guide rail 7 bottom, solenoid 6 installs in guide rail 7 outer end.

As shown in fig. 2, when only the passage portion of the valve body 1 needs to be opened, the control end controls the guide rail 7 to move down, so that the magnetic block 5 adsorbs the valve iron block 4, and then the valve iron block 4 moves up to the specified position along the flow control cavity 4 and the extension cavity 3, so that the valve body 1 is in the specified opening, the position of the valve iron block 4 is kept unchanged, and the flow control purpose is achieved.

As shown in fig. 3, when only the passage of the valve body 1 is changed from the open state to the closed state, at this time, the valve iron block 4 is in a partially open state or a fully open state, the magnetic block 5 adsorbs the valve iron block 4, the control end control guide rail 7 moves down until the valve iron block 4 contacts the bottom of the flow control cavity 4, at this time, the passage in the valve body 1 is completely blocked by the valve iron block 4, and the valve body 1 is in the closed state.
