Abstract
The invention relates to an electric blowdown valve which comprises a valve body. A valve cover is arranged on the valve body, and a rotary valve is arranged in the valve body. The electric blowdown valve is characterized in that the rotary valve is connected with a speed reducing motor through a connecting shaft, and the speed reducing motor drives the rotary valve to rotate to be open and closed and is connected with a driving unit which is connected with an external control unit. The speed reducing motor is adopted to drive the rotary valve to be in open-closed motion, and forward rotation and backward rotation of a motor are controlled by receiving signals of a contactor switch or a PLC (programmable logic controller) switch to control opening and closing of the valve, so that the circumstance that the valve is not closed completely is avoided. The electric blowdown valve has the advantages of stability in running, noiselessness, freeness of impact force and the like.
Description
Technical field
The present invention relates on a kind of industrial automation production line, the final controlling element of the flowing medium emission controls such as water, liquid, washing agent uses in the industrial manufacturing service industries such as washing, light industry, food, medical treatment.
Background technique
The final controlling element of the flowing medium emission controls such as existing water, liquid, washing agent is mechanical spring type blowdown valve, and it is made of valve body parts, drive motor, spring reverse motion and changeover valve parts etc. usually.The changeover valve parts rely on the drive motor Unscrew, then close by spring reset, reach the purpose of opening fluid and fluid transfer.Spring reverse motion is connected by bolt with valve body parts, and changeover valve is placed in the positioning hole of valve body by the rotatingshaft at two ends.Drive motor is connected with changeover valve by coupling shaft.Because the spring closing motion is unreliable, when running into change in fluid pressure, can not be adjusted accordingly, and causes valve often to occur being not closed completely, and the fluid leaks phenomenon occurs, cause work system regular quality problems to occur.Valve closing is not tight, has also seriously affected energy-conserving and environment-protective, on the one hand because seepage has affected environmental protection, in safeguarding and adjusting, has wasted a large amount of energy consumptions on the other hand.
Summary of the invention
The technical problem to be solved in the present invention provides the tight blowdown valve of a kind of valve closing.
In order to solve the problems of the technologies described above, technological scheme of the present invention has provided a kind of electronic blowdown valve, comprise valve body, valve gap is located on the valve body, be provided with changeover valve in valve body, it is characterized in that: changeover valve links to each other with reducing motor via coupling shaft, is rotarily opened and rotary closing by reducing motor driven rotary valve, reducing motor connects driver element, and driver element connects external control unit.
Preferably, be provided with O-ring seal at described valve gap.
Preferably, described reducing motor and described driver element are positioned at casing, and casing is located on the described valve body, and described coupling shaft passes described valve body and links to each other with described changeover valve, seals with seal ring by axle between described coupling shaft and the described valve body.
Preferably, be provided with working station indicator at described casing, working station indicator connects described driver element.
Preferably, described driver element and described reducing motor are via the transformer access external power supply that is positioned at described casing.
Preferably, be provided with openable top cover at the top of described casing.
Preferably, described valve body, described changeover valve and described casing all adopt engineering plastics to make.
Make, service industry, used in large quantities flowing medium---air, water, etc. go to carry out the work such as powered, material mix, article cleaning.And a large amount of valve of these needs of work carries out the fluid pipage control, needs integrated control, with reach regularly, quantitatively, the running of fixed cycle.The present invention develops for finishing these work exactly, and the present invention is the industrial valve class final controlling element of making for adapting to automation.
The present invention adopts reducing motor to drive changeover valve and opens and closes motion, by receiving the switching signal of contactless contactor or PLC, the clockwise and anticlockwise of control motor, thereby the folding of control valve, avoided the not tight situation of valve closing to occur, the present invention has smooth running, noiseless, without advantages such as impact forces.
Description of drawings
Fig. 1 is the structural representation of a kind of electronic blowdown valve provided by the invention.
Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, the invention provides a kind of electronic blowdown valve, comprise valve body 3 and valve gap 1, at valve gap 1 O-ring seal 2 is installed.Changeover valve 12 is arranged in valve body 3.At the casing 9 that valve body 3 is installed with top cover 11, reducing motor 8, driver element 7 and transformer 6 are installed in the casing 9, installment work status indicator lamp 10 on casing 9.Coupling shaft 4 is connected on the output shaft of reducing motor 8, and its end is passed valve body 3 and connected changeover valve 12, seals with seal ring 5 by axle between coupling shaft 4 and the described valve body 3.Rotarily opened and rotary closing by reducing motor 8 driven rotary valves 12.Reducing motor 8 and working station indicator 10 connect driver element 7, and driver element 7 connects external control unit.The driver element 7 and the reducing motor 8 that are positioned at casing 9 access external power supplys via transformer 6.
The pipeline pipe is connected on the import and export passway on the valve body provided by the invention, when the switch of accepting contactless contactor or PLC of control unit receives signal, control reducing motor 8 rotates, reducing motor 8 driven rotary valves 12 are opened, working station indicator 10 green lights are bright, medium fluid begins to flow and carries, treat that the fluid conveying is complete, control unit sends signal again, reducing motor 8 backward rotation, reducing motor 8 driven rotary valves 12 are closed, working station indicator 10 when reds, medium fluid is blocked, and stops to flow.A work cycle finishes.When control unit sends signal again, repeat above-mentioned work.So constantly carry out periodic duty.
