First mouth of a river and second mouth of a river excessively excessively is sector.

The upper flap 12 and lower Disc 13 are copper material.

Below to being described using process：Primarily with respect to digital locked balance valve component, balanced using number lock When valve module, the hand-operated valve 22 closed on connecting pipe 21, the pressure regulation needle 23 closed at pressure guide hole 19 is only adjusted in regulation Exposed junction of the bar 6 at bonnet, 2, rotation set 8 is rotated by its rotation, can make face thereon by the rotation of rotation set 8 First, which crosses the mouth of a river, rotates, and can so adjust first and cross the mouth of a river and the second registration crossed between the mouth of a river, to change flow, water warp Entered after crossing the first overlapping region excessively between the mouth of a river and the second mistake mouth of a river inside spring strut 9, then pass through the inwall of spring strut 9 Space between spring bracket 10 is entered in the space of the lower section of spring strut 9, while rotating on adjusting rod 6 can drive digital display piece The different traffic figure of 7 displays, can intuitively read traffic figure, now the valve possesses the work(of digital locked balance valve Energy.Using cooperatively due to rotation set 8 and spring strut 9, instead of the way in the past using sheet flow regulating plate so that more herein Plus Stability Analysis of Structures, sensitivity is more preferable.

On Self-operated flow control assembly, connecting pipe 21 is closed when in use, pressure regulation needle 23 is reached maximum, adjust Upper adjusting rod 6 reaches certain flow value, then when there is pressure difference in the water inlet 4 and valve pocket of valve, can be by certainly Power formula flow control assembly is adjusted, and when being specially that pressure increases at water inlet 4, current are entered down by pressure guide hole 19 At bonnet 3, in the inner chamber for entering bottom flange 3, so that the lug boss of ejection diaphragm 18, so that diaphragm 18 is moved up, from And the motion upwards of lower dolly bar 14 is driven, upper film pad 26 is moved therewith when diaphragm 18 is with motion, moves to lower outlet When play spacing effect, and lower dolly bar 14 can make the spring 17 in spring strut 9 to produce pressure when move upwards Contracting, upper flap 12 and lower Disc 13 turn the size of upper water-out mouthful 15 and lower outlet 16 down, and such water amount just diminishes, will not Because the pressure of water inlet 4 becomes big and increases flow, the purpose of constant flow rate is reached, if instead the pressure of water inlet 4 reduces, film Piece 18 rebounds in the presence of spring 17, so as to increase the size of upper water-out mouthful 15 and lower outlet 16, increases water amount, together Sample makes flow constant, now plays spacing effect between spring bracket 10 and upper water-out mouthful 16.Bullet unlike before herein Spring 17 does not play a part of directly conducting, but in the drive reverse compression spring 17 of lower dolly bar 14, plays 17, spring To an effect for providing reverse reset force, compared to pre-structure it is simpler, service life is longer.

On self-operated type pressure difference control assembly, in use, opening the hand-operated valve 22 on connecting pipe 21, closing pressure-regulating valve pin 23, the upper turn of adjusting rod 6 to fully open position, the other end connection feed pipe of connecting pipe 21, this valve is arranged on return pipe, Current enter regulator hole 20 by connecting pipe 21, in the inner chamber for entering bottom flange 3, and then ejection diaphragm 18, make lower valve Valve works automatically, keeps the pressure difference of controlled system constant, plays a part of Differential Pressure Controller.By pressure regulation needle 23, The size of the aperture of pressure guide hole 19 is adjusted, the magnitude of pressure differential of controlled system is adjusted.

The utility model had the effect that, the valve except the repertoire that has with Multifunctional balance valve it Outside, mainly spring is arranged in the spring strut on top, and ejection is not carried out directly by spring, but diaphragm by Compression stress is produced to spring-compressed by lower dolly bar during effect of water pressure, it is to avoid direct contact, overall structure is simple, increase Service life, and employ two kinds of tubular structures of spring strut and rotation set and instead of conventional laminated structure, add stabilization Property and regulation sensitivity.
