Abstract
The utility model relates to an automatically closing device for a pipe-line valve. The device drives a speed variator 2 by a motor 1 to control the opening and the closing of a pipeline valve 5. The utility model is characterized in that the output end of the speed variator 2 is connected with a U-shaped moving holder 3, and a valve rod 4 on the valve 5 is arranged in the U-shaped port of the U-shaped moving holder 3. The upper part of a movable shaft 7 of a cylindrical gear in the speed variator is provided with a spring 8, and push buttons 9 are arranged on the upper ends of the shaft 7 and the spring 8. The operating distance of the button 9 is agreeable for disengaging the engagement of a cylindrical gear 6 of the speed variator 2 and a disk-shaped gear 10. The utility model has the advantages of simple structure, low cost, and wide purpose, easy remote operation, etc.
Description
The utility model relates to a kind of valve control device, especially a kind ofly is used for remote valve self-closing device.
At present, the various control gear that are used for pipeline are varied, specifically can be divided into closely control gear and remotely controlled plant two big classes.The most complex structure of remotely controlled plant, cost height.Because the remotely controlled plant complex structure, or be more or less to exist potential safety hazard; Be to be used for single pipeline control,, can only be used for gas pipeline control as ZL93229211.9 utility model patent disclosed " a kind of gas safe energy-saving automatic control device ".
The purpose of this utility model is to provide a kind of various pipelines and can remote operated valve self-closing device of being applicable to.
The utility model above-mentioned purpose realizes by following technological means.
A kind of pipeline valve self-closing device, this device is opened and closed by motor driving speed change gear control valve, it is characterized in that being equipped with the U type on the output axle head of said speed change gear removes folder, and the valve rod on the valve is arranged on the U type and removes in the U type mouth of folder.When needs keying pipeline valve, as long as being arranged on the U type by the speed change gear drive, starting electrical machinery removes the interior valve rod rotation of folder, just the may command pipeline valve opens and closes.
The disk gear that assembles on the cylindricality gear that assembles on the movable axis in the above-mentioned speed change gear and the stationary axle is meshed, and on the movable axis of cylindricality gear spring is housed, and is provided with in the upper end of axle and spring and controls cylindricality gear and the out-of-gear button of disk gear.The operating distance of this button is separated from the engagement that can make cylindricality gear and disk gear and is advisable.
Open and close in order to make valve rod in setting range, rotate control valve, be provided with the block that two control tooth sector rotate with the corresponding the other end of tooth sector in 90 degree scopes on the fixed plate in the above-mentioned speed change gear.
The utility model has been owing to adopted the motor driving speed change gear to drive valve rod work, so structure is very simple, but and remote operation; Again because the utility model also is provided with hand push button, so even power failure, still operable valve door.In sum, the utlity model has simple in structure, cost is low, purposes is wide, and is easy to advantages such as remote operation.
Introduce the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Find out that by Fig. 1 driving gear 11 is connected with the output shaft of motor 1, and mesh with driven gear 12; Driven gear 12,13 is located on the axle 14, gear 13 and gear 15 engagements; Tooth commentaries on classics 15 and gear 16 are located on the axle 17, gear 16 and gear 18 engagements; Gear 18 and gear 19 are located on the axle 20, and gear 19 is meshed with cylindricality gear 6; Above-mentioned cylindricality gear 6 is assemblied on the movable axis 7, is meshed with disk gear 10 on the stationary axle 22; Disk gear 10 and gear 21 are located on the axle 22, and gear 21 is meshed with tooth sector 23; Tooth sector 23 is removed folder 3 with being contained on the axle 24 with the U type, and the valve rod 4 on the valve 5 is in the U type just and removes in the U type mouth of folder 3.When needs opened and closed pipeline valve, tooth sector 23 and the axle 24 of starting electrical machinery by the speed change gear output terminal drove and is positioned at the U type and removes valve rod 4 rotations of folder 3 and opening/shutting valve 5.
In addition, on the movable axis 7 of gear 6, spring 8 is housed, is connected with button 9,, press the button 9 the cylindricality gear 6 and the engagement of disk gear 10 are separated from, thereby realize manual-lock valve 5 in case have a power failure in the upper end of axle 7 and spring 8.Behind the release button 9, rely on the elastic force of spring 7 that cylindricality gear 6 is meshed with disk gear 10 again.
