Description
Technical field
The utility model relates to a kind of valve automatic opening-closing, refers in particular to, and is used for that gate valve, stop valve are opened automatically, closed device.
Background technique
In the prior art, many gate valves, stop valve often are installed on water pipe, the steam line, such as, on the various pipes of Baosteel plant area, up to ten thousand gate valves, stop valve are installed, in daily repair and maintenance, need throttle down in order to finish the maintenance of corresponding site pipeline, equipment replacement.Opening/shutting valve is by artificial rotation at ordinary times, and working strength is very large, is that the valve of 500mm needs two to three people to cooperate such as opening or closing diameter, and the method that adopts pipe tongs to add sleeve just rotates that needs spend 30 minutes; And because differences such as new and old, big or small, the installation positions of valve, the reason such as employee's age structure is bigger than normal is often sprained phenomenon during employee's opening/shutting valve, has potential safety hazard.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of valve automatic opening-closing, can automatically open or close valve, alleviates to greatest extent operative employee's labor intensity.
The technological scheme that the utility model addresses the above problem is as follows:
A kind of valve automatic opening-closing is characterized in that:
It comprises hub type brushless DC motor, be connected with below the wheel hub of described direct current generator 3 with the wheel hub bottom surface perpendicular open valve rod, described wheel hub top is provided with the circular safety enclosure that is fixed on the motor stator, motor control box and control switch are installed above the described safety enclosure, and the both sides of described safety enclosure are installed with handle.
To offer adjustment hole on the described wheel hub as further improvement.Be convenient to regulate the position of opening valve rod.Open valve rod and can be bolted in the adjustment hole, the position of opening valve rod by adjusting adapts to the demand that opens and closes different valves.
Further, described 3 are opened valve rod and evenly arrange along the circumferencial direction of wheel hub.That is to say, 3 are opened the line of valve rod and motor stator with the disk even partition at wheel hub place, and the angle between line is 120 ° in twos.
Further, the radius of described wheel hub is 150mm～250mm.Like this, this device can act on most gate valve or stop valve.
According to the size of wheel hub, described safety enclosure diameter is 550mm.
Further again, the gross weight of described valve automatic opening-closing is 3kg～5kg.Convenient operation personnel carry.
Working principle of the present utility model is, operator hold handle, and in 3 open disks that open the valve rod insertion valve, when control switch is allocated to when opening, the electric energy of storage battery converts kinetic energy to by control circuit drive hub formula direct current generator.At stator fixedly the time, the speed that rotor turned with 2 seconds 1 (or slower speed) drives wheel hub and rotates, and three open disks that open valve rod drive gate valve (stop valve) that are installed on the wheel hub rotate simultaneously, and the screw thread of valve rod is under the effect of rotating in the time of rotation, constantly upwards promote until to the top, at this moment the moment of motor strengthens suddenly, and greater than the torque setting value, control circuit voltage rises, the comparator counter-rotating, output voltage is zero, and motor stops operating, and finishes breakdown action one time.
When the needs throttle down, control switch is allocated to closes driven by motor wheel hub backward rotation, three open disks that open valve rod drive gate valve (stop valve) that are installed on the spoke rotate simultaneously, the screw thread of valve rod constantly descends until on earth downwards under the effect of rotating when rotating, and at this moment the moment of motor strengthens suddenly, greater than the torque setting value, control circuit voltage rises, the comparator counter-rotating, and output voltage is zero, motor stops operating, and finishes closing motion one time.
The beneficial effects of the utility model are:
1, use this device, Open valve does not need just can rotating valve with pipe tongs, greatly reduces employee's labor intensity.
2, working efficiency is greatly improved, and such as opening or closing the valve that diameter is 500mm, uses this device, only needs 1 operator just can easily open valve.
3, because this device can the automatic rotating valve rod, sprain when having avoided employee's rotating valve, increased safety coefficient.
4, greatly shorten the opening time of valve, equipment downtime is significantly reduced, ensured the energy medium supply of production line, guaranteed carrying out smoothly of production.
Description of drawings
