Abstract

The utility model relates to a solenoid valve that is used to control the flow of fluid medium in a pipeline, in particular to a power-saving solenoid valve that can be operated manually; the solenoid valve comprises a valve body, valve ports, a valve base, a solenoid, a magnetic core, a diaphragm, a valve stem, a position indicator, a power controller, and power wires; wherein, a screw hole is arranged coaxially to the valve stem on the bottom of the valve body, and a valve port opening screw rod is located in the screw hole; wherein, the screw rod matches the screw hole and is screwed in into the valve body, and has a hand wheel on the bottom, and the top end of the screw rod can contact with the valve stem. The advantages of the utility model include: in case of power outage due to failures, the valve port can be opened with the valve port opening screw rod as required, so as to ensure normal flow of the fluid medium and meet the demand for normal production and living, and avoid unnecessary economic loss.

Description

But hand behaviour economize on electricity solenoid valve

Technical field

The utility model relates to flowing medium switching solenoid valve in a kind of control fluid circuit, but relates in particular to a kind of hand behaviour economize on electricity solenoid valve.

Background technique

In industrial pipeline control system such as oil, chemical industry, medicine and domestic gas, water supply, heat supply pipeline control system, extensively adopt the control gear of solenoid valve as control flows body medium break-make, especially the solenoid valve of being furnished with power controller, because of but its saving power consumes more than 50%, and the electromagnetic coil temperature is dropped to below 40 ℃, more become the first-selection in the application of solenoid valve product.Yet the economize on electricity solenoid valve of existing employing power controller can't proper functioning after power supply system breaks down, can only be out of service wait power supply line repair, like this, not only cause industrial economic loss but also make troubles to service-user.

The model utility content

Main purpose of the present utility model is to provide a kind of economize on electricity solenoid valve that has hand behaviour opens solenoid valve device at above-mentioned defective, make under outage condition by manually-operable, solenoid valve can work on, thereby ensured industrial carrying out continuously and the regular supply of domestic gas, water, heat, avoid industrial loss, reached customer satisfaction system service.

The technological scheme that its technical problem that solves the utility model adopts is: but a kind of hand behaviour economize on electricity solenoid valve, form by valve body, valve port, valve seat, electromagnetic coil, magnetic core, diaphragm, valve rod, position indicator, power controller and power cable, it is characterized in that bottom and the coaxial tapped hole that is provided with of valve rod at valve body, in tapped hole, have one adaptively with it and screw in the unlatching valve port leading screw that its lower end in the valve body has handwheel, open valve port leading screw top and be accessibly connected valve rod.

The utility model has the advantages that: under situation, can adopt unlatching valve port leading screw to open valve port as required, guarantee that flowing medium is unimpeded, guarantee the needs of ordinary production and life, avoid unnecessary economic loss because of various fault outages.

Description of drawings

Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in detail.

But accompanying drawing is the sectional view of normal close type hand behaviour economize on electricity solenoid valve.

Among the figure: 1 valve body, 2 valve ports, 3 valve seats, 4 electromagnetic coils, 5 magnetic cores, 6 diaphragms, 7 valve rods, 8 position indicators, 9 power controllers, 10 power cables, 11 tapped holes, 12 open valve port leading screw, 13 flowing mediums

Embodiment

But as shown in drawings, be a kind of hand behaviour economize on electricity solenoid valve, form by valve body 1, valve port 2, valve seat 3, electromagnetic coil 4, magnetic core 5, diaphragm 6, valve rod 7, position indicator 8, power controller 9 and power cable 10, it is characterized in that bottom and the valve rod 7 coaxial tapped holes 11 that are provided with at valve body 1, have one adaptively with it and screw in the unlatching valve port leading screw 12 that its lower end in the valve body 1 has handwheel in tapped hole 11, unlatching valve port leading screw 12 tops are accessibly connected valve rod 7.

Set forth its working principle below in conjunction with accompanying drawing: as shown in the figure, magnetic core 5 is connected as a single entity with valve rod 7, diaphragm 6, valve port 2 is connected as a single entity with valve rod 7 again, to normal close type economize on electricity solenoid valve, when power cable 10 normal power supplies, electromagnetic coil 4 has electric current by generating an electromagnetic field, magnetic core 5 is picked up, at this moment, valve rod 7 with on move, diaphragm 6 also with on move, valve port 2 moves away valve seat 3 on also, and at this moment, solenoid valve is opened, flowing medium 13 enters in the valve body 1 and through hole by valve seat 3 flows out from valve body 1 outlet from an end entrance, can find out the position that valve port 2 rises from the position indicator 8 that valve port closes; When power cable 10 cuts off the power supply owing to fault, because of no current passes through electromagnetic coil 4, magnetic field diminishes, magnetic core 5 falls back to initial position, at this moment, valve rod 7 also falls back to initial position thereupon, and diaphragm 6 resets, valve port 2 covers on the valve seat 3, closed electromagnetic valve, and flowing medium 13 can not pass through valve body 1; At this moment, according to producing or use needs, the handwheel that turns clockwise makes opens 12 risings of valve port leading screw, make its top contact connect valve rod 7 and it is continued the top that makes progress, push up the correct position of determining by position indicator 8, this moment, valve port 2 was lifted off a seat 3 desired location, and solenoid valve is opened, thereby continued to keep flowing medium unimpeded.In case power supply trouble is got rid of, then be rotated counterclockwise handwheel unlatching valve port leading screw 12 is descended, make its top be separated from valve rod 7, valve rod 7 descends and covers on valve seat 3 closed electromagnetic valve until valve port 2 again; Connect power cable 10 then, make solenoid valve proper functioning under electric power control.

Claims

But 1, a kind of hand behaviour economize on electricity solenoid valve, form by valve body, valve port, valve seat, electromagnetic coil, magnetic core, diaphragm, valve rod, position indicator, power controller and power cable, it is characterized in that bottom and the coaxial tapped hole that is provided with of valve rod at valve body, in tapped hole, have one adaptively with it and screw in the unlatching valve port leading screw that its lower end in the valve body has handwheel, open valve port leading screw top and be accessibly connected valve rod.
