Self-operated type pressure difference control assembly is to connect the second branch pipe 20 of 3 inner cavity of bottom flange, the end of second branch pipe 20 Opening, second branch pipe 20 are equipped with the second needle-valve 30, and first branch pipe 19 is also connected with the connectivity part of the second branch pipe 20 There is relief tube 23, ball valve 22 is equipped with the relief tube 23.

It is open described in 18 face of diaphragm at 29 with the lug boss annular in shape to arch upward.

Lower spring bracket 25 is located in the inner cavity of bottom flange 3 and hanging setting, the inner wall of the upper spring bracket 24 and the valve body are fixed Connection.

Upper flow regulating plate 8 and down-off adjustment sheet 9 are made of stainless steel.

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

Upper flap 12 and lower Disc 13 are copper material.

For upper flow regulating plate 8 to be circular, second on the upper flow regulating plate 8 crosses the mouth of a river as symmetrically arranged two, Described second, which crosses the mouth of a river, extends along the change rate of direction openings of sizes and becomes larger, and described first crosses the mouth of a river crosses the mouth of a river with second Shape it is identical.

Below to being described using process：Primarily with respect to digital locked balance valve component, balanced using number lock When valve module, the first needle-valve 21 and the second needle 30 on the first branch pipe 19 and the second branch pipe 20 are simultaneously closed off, is also switched off Ball valve 22 on relief tube 23, only adjusts upper exposed junction of the adjusting rod 6 at bonnet, 2, and the first mistake is adjusted by its rotation Registration between the mouth of a river is crossed at the mouth of a river and second, to change flow, while rotating on adjusting rod 6 digital display piece 7 can be driven aobvious Show different KV values, flow value can be converted into, the valve possesses the function of digital locked balance valve at this time.

On Self-operated flow control assembly, the second needle-valve 30 closed when in use on the second branch pipe 20 simultaneously closes off Ball valve 22 on relief tube 23, opens the first needle-valve 21 on the first branch pipe 19 and reaches maximum, adjusting rod 6 reaches in adjusting Certain flow value, then when there is pressure difference in the water inlet 4 and valve chamber of valve, can pass through Self-operated flow control group Part is adjusted, and when pressure increases specially at water inlet 4, current are entered at bottom flange 3 by the first branch pipe 19, enters Into the inner cavity of bottom flange 3, so that the lug boss of the opening ejection diaphragm 18 from upper spring bracket 24, so that diaphragm 18 is to moving up Dynamic, so as to drive lower dolly bar 14 to move upwards, and lower dolly bar 14 moves upwards when, can drive lower spring bracket 25 to transport at the same time Dynamic, the spring 17 so descended between spring bracket 25 and upper spring bracket 24 can produce compression, upper flap 12 and lower Disc 13 by upper water-out mouth 15 and the size of lower outlet 16 turn down, such water amount just diminishes, and will not become larger due to 4 pressure of water inlet and increase flow Add, achieve the purpose that constant flow rate, if instead 4 pressure of water inlet reduces, diaphragm 18 rebounds under the action of spring 17, so that Increase the size of upper water-out mouth 15 and lower outlet 16, increase water amount, equally make flow constant, lower film pad 27 is downward at this time Moving contact plays the role of lower limit to upper spring bracket 25 moves stopping.From before unlike spring 17 herein do not have To the effect directly conducted, but the 25 reverse compression spring 17 of spring bracket under the drive of lower dolly bar 14, only serve spring 17 One offer reversing reset power effect, compared to pre-structure it is simpler, service life is longer.

On self-operated type pressure difference control assembly, in use, opening the second needle-valve 30 on the second branch pipe 20, first is closed The first needle-valve 21 on pipe 19, closes the ball valve 22 on relief tube 23, upper 6 turn of adjusting rod to fully open position, the second branch pipe 20 openend connection feed pipe, this valve are arranged on return pipe, and current enter bottom flange 3 by the second branch pipe 20 In inner cavity, and then ejection diaphragm 18, lower Disc is worked automatically, keep the pressure difference of controlled system constant, play self-operated type pressure The effect of poor control valve.By the second needle-valve 30, the size of adjusting 20 aperture of the second branch pipe, the pressure difference for adjusting controlled system is big It is small.

It is illustrated in figure 3 the structure diagram of flow regulating plate, the structure of down-off adjustment sheet 9 and upper flow regulating plate 8 structure is the same, both align up and down, by the opening shape in figure on upper flow regulating plate 8 it is known that when being rotated from Rise, rotate same angle, the size that two adjustment sheet upper sheds align is increasing, i.e., change rate is increasing, so sets It is requirement in order to meet flow component and pressure difference component to put, and pressure difference is excessive sometimes, can not be protected if opening very little is aligned It is constant to demonstrate,prove flow, so pivoted eyelid again, increase opening change rate, then can meet that flow is constant, so meet to flow at the same time Amount balance and pressure balance.

Effect possessed by the utility model is, the valve except with repertoire possessed by Multifunctional balance valve it Outside, most important inventive point is different from internal-hole type before, and the pressure guide hole of flow control assembly is arranged to external shape Formula, an entirety is connected into by the connecting pipe of itself and pressure difference control assembly, more convenient to use easy to overall control and maintenance.
