108, control chamber 109 is formd between diaphragm 105 and valve deck 104；Pass through diversion pipe 110 between intake antrum 108 and control chamber 109
It is connected to, regulation pipe 111 is connected on the diversion pipe 110, regulation pipe 111 is equipped with pilot valve 112.
This list diaphragm hydraulic control valve mainly improves the control structure of hydraulic control valve, can be referred to as water
Force control valve.
Main valve 101 is the main components of the hydraulic control valve, main valve 101 by its input end 102 and outlet end 103 with
Other pipelines are connected；Valve deck 104 is detachably connected with main valve 101, facilitates the processing and assembly of valve deck 104, in valve deck 104 and master
Hemispheric diaphragm 105 there are one being set between valve 101, which is flexible, passes through the elastic reaction of diaphragm 105
Finally realize the control action of the hydraulic control valve.
There are three types of states for hydraulic control valve tool, specifically work in this way：
1. full-shut position (as shown in Figure 8)：Pilot valve 112 outside main valve 101 is closed, 101 input end of main valve, 102 pressure
Water enters control chamber 109 by diversion pipe 110, until the cavity pressure is equal with input end 102, diaphragm 105 and blocking
Face 107 is bonded completely, and main valve 101 completely closes；
2. working condition (as shown in Figure 9)：The aperture for adjusting 101 external pilot valve 112 of main valve, makes its water flow and flows through
The water flow of diversion pipe 110 reaches balance, and diaphragm 105 is slightly separated with blocking surface 107 at this time, and main valve 101 is in running order；
3. full-gear (as shown in Figure 10)：After 112 standard-sized sheet of pilot valve outside main valve 101, water in control chamber at this time
It all is discharged into the external world, diaphragm 105 is kept completely separate with blocking surface 107, and input end 102 is connected to completely with outlet end 103, main valve
101 are shown in a fully open operation.
The other end of regulation pipe 111 can be communicated directly with the external world, can also be communicated with outlet end, and adjusting water is made to pass through
It flows out at mouth end 103.
In this hydraulic control valve, what is played a major role is the opening and closing of diaphragm 105, and the material of diaphragm 105 may be used
Rubber is made, and adds corresponding additive, its mechanical property is made to meet the requirements.A diaphragm is only needed in this hydraulic control valve
105, pass through the control action of the components such as pilot valve 112, so that it may very convenient quick to realize the control of waterpower.
Therefore, this single diaphragm hydraulic control valve improves its control structure, make its course of work with it is traditional
Hydraulic control valve has the difference of matter, not only solves the susceptible to plugging problem of valve content, and make the control of waterpower more square
Just, diaphragm 105 and 101 internal part of main valve are substantially not present friction, for a long time using diaphragm 105 will not be made to wear,
Be conducive to improve the service life of entire hydraulic control valve, reduce engineering cost.
The effect of barrier structure 106 and blocking surface 107 is, coordinates diaphragm 105, disconnects input end 102 and outlet end 103
Between connection, therefore its concrete structure those skilled in the art can be rule of thumb designed by the enlightenment.In some tools
In body embodiment, in the projection of horizontal plane, the length direction of blocking surface 107 mutually hangs down main valve 101 with the axis direction of main valve 101
Directly.
As shown in figure 3, the blocking surface 107 of this structure design is matched with hemispheric diaphragm 105, therebetween relatively
Easy to produce close fitting, its control action easy to implement.
In order to improve connection relation between diaphragm 105 and blocking surface 107, can also be arranged on the spherical outside surface of diaphragm 105
The protrusion 113 of arc, the groove 114 that setting matches with the protrusion 113 on blocking surface 107.When diaphragm 105 and blocking surface
When 107 fitting, protrusion 113 cooperates with groove 114, makes to coordinate more closely between diaphragm 105 and blocking surface 107.
Diaphragm 105 is arranged between valve deck 104 and main valve 101, and specific connection type can be diversified, such as：
It is connected with the flange 115 of circular ring shape in the opening of diaphragm 105, multiple rings are equipped on valve deck 104, flange 115 and main valve 101
The through-hole 116 of shape distribution.As shown, in connecting components, each through-hole 116 is coincided, it can by bolt and nut
The connection of each component is realized securely.Meanwhile bolt passes through diaphragm 105, makes to deposit between diaphragm 105 and valve deck 104 and main valve 101
It in true connection relation, rather than only presses between, it can be ensured that hydraulic control valve diaphragm in use
105 will not be changed position by the impact of high pressure water flow, are not in unnecessary gap or loosening, are enable control work just
Often carry out.
Optionally, nonwoven layer is equipped in diaphragm 105.Non-woven fabrics setting can facilitate diaphragm 105 inside diaphragm 105
Molding makes diaphragm 105 have better toughness and intensity.
In some specific embodiments, also of a design such that：Conical Projectile is equipped between diaphragm 105 and valve deck 104
Spring 117, the larger one end of the volute spring 117 are in contact with the medial surface of valve deck 104；105 inside of diaphragm is equipped with connector
118, which includes two coaxial connected and different-diameter column link blocks, the outer diameter of the smaller link block of diameter
The internal diameter of one end smaller with volute spring 117 matches, the end face phase of the end of volute spring 117 and the link block being relatively large in diameter
Contact.
In the case of spring is not set, it can realize that its controls mesh by hydraulic pressure and diaphragm 105 elastic reaction of itself
's.When hydraulic control valve is in full-shut position, pilot valve 112 is closed, and needs hydraulic control valve being adjusted to work
Opening pilot valve 112 is needed to throw open 112 high pressure water flow of pilot valve since 108 inside water pressure of intake antrum is very big when state
Rapidly outlet end 103 can be flowed to by compressing diaphragm 105.The presence of such case can cause hydraulic pressure in hydraulic control valve unstable, no
Conducive to the Linear Control of hydraulic pressure, it is also easy to cause the damage of precise part under some accurate occasions.
After provided with volute spring 117, volute spring 117 is in compressive state, when pilot valve 112 is become out from closing
Qi Shi, high pressure water oppress diaphragm 105 when due to volute spring 117 presence, so that flow is unlikely to presses against diaphragm too quickly
105, so that hydraulic pressure is smoothly controlled, keeps the pressure release of the hydraulic control valve more linear.Meanwhile in full-shut position, every
Hydraulic pressure is consistent inside and outside film 105, is acted on from 105 inside of diaphragm the pressure of diaphragm 105 by volute spring 117, makes diaphragm 105
It can be more closely bonded with blocking surface.Hydraulic control valve from working condition when becoming full-shut position, by volute spring 117
Elastic reaction enables working condition fast transition, reduces outlet end hydraulic pressure.
In addition, high pressure conditions are in intake antrum 108 always, and by 106 groups of outlet end 103, diaphragm 105 and barrier structure
At water chamber in hydraulic pressure play pendulum.When hydraulic control valve is in working condition by full-shut position transformation after film 105
Both sides pressure difference changes greatly, and diaphragm 105 since the compressing of high pressure water will appear the situation being recessed inwardly, hold by the presence of this situation
The offset for easily causing volute spring 117 can not play respective action if volute spring 117 is departing from its home position.
Thus connector 118 is additionally provided in 105 inside of diaphragm.
Connector 118 is divided to for the link block of two different-diameters, and connector 118 is preferably made of metal, at the time of molding
It can be integrally formed with diaphragm 105.The internal diameter of the outer diameter and the smaller one end of volute spring 117 of the smaller link block of diameter
Match, its smaller one end is placed on the outside of link block after so that volute spring 117 is connect with diaphragm 105, and link block is from volute spring
Restriction effect is played in 117 side to it, makes diaphragm 105 that will not cause the displacement of volute spring 117 in deformation, makes taper
Spring 117 can be in correct position always, and stable working environment is provided to waterpower control work.
It can also further design in this way：Valve deck 104 is circle, and inside is equipped with diameter and is less than the convex of 104 diameter of valve deck
Platform, the diameter of the boss are less than or equal to the diameter of diaphragm 105.After diaphragm 105 is fixed, boss is located at the inside of diaphragm 105, side
Civilian dress matches the positioning of process septation 105.(it is hemispheric situation shown in the drawings of valve deck 104.At this time inside valve deck 104
It can be not no boss.Can have boss when valve deck is circle.)
Further, barrier structure 106 also has other stop members：The both sides of blocking surface 107 are respectively provided with an auxiliary
The wherein both sides of supporting block 120, auxiliary support block 120 are fixedly connected with the inner wall of barrier structure 106 and main valve 101, auxiliary branch
Bracer 120 further includes the supporting surface of arc, which fits with diaphragm 105.As shown, blocking surface 107 and two it is auxiliary
Supporting block 120 is helped to form cross barrier structure 106, this structure can steadily play hemispheric diaphragm 105
Support and barrier effect, while auxiliary support block 120 can also play the role of reinforcing hydraulic control valve intensity, make its long-time
Will not occur deforming after use or crackle.
Further, needle valve 121 is equipped on diversion pipe 110.Needle valve 121 can control the opening and closing of diversion pipe 110.
Further, the outside of input end 102 and outlet end 103 is equipped with groove structure 122 or flange connector.Tradition
Hydraulic control valve be substantially using flange and piping connection, this connection type more tradition fall behind, area occupied is larger,
The connector 118 that needs is more, connects more time-consuming, and it is impossible to meet the demands of fast assembling-disassembling, and to installation personnel
Specialized capability it is more demanding.Flange connection can also realize its connection.
The connection type of groove structure 122 is relatively new connection type, has the advantages that a variety of, is that traditional flange connects
It is unrivaled to meet or weld institute.
1. easy to operate
The attended operation of groove pipe fitting is very easy, is not necessarily to special professional skill, common laborer is by simple
Training can be operated.This is because a large amount of fine technology segment has been added to finished product by product in a manner of batch production
In.Pipe fitting connection only needs a few minutes clock time at one, maximally simplifies the technical difficulty of execute-in-place, saves working hour, from
And construction quality is also stabilized, it improves work efficiency.This is also the general direction of mounting technique development.
And the pipeline connection type of traditional welding and flanged joint, the welder of corresponding technical ability is not only needed, and
And it is time-consuming, the operation difficulty of worker is big, and there are the pollutions of weld fumes.Due to the difference of operating space and welding technical ability, weldering
Quality and appearance is connect all to be difficult to reach satisfied as a result, to influence the total quality of engineering.
In addition, since groove pipe fitting is finished parts, the required operating space in scene is small, can really realize and lean on angle by wall
Installation, operation difficulty greatly reduces, and to save floor space, has beautified the effect of Pipe installing.
2. the original characteristic of pipeline is unaffected
Groove pipe fitting connects, and does not destroy inner wall of the pipe structure, this is that groove pipe fitting connects distinctive technological merit.If adopted
It is operated with traditional welding, the pipeline that many inner walls did erosion resistant coating will all be destroyed.Therefore specification provides zinc-plated pipeline, lining
Plastic Steel Pipe, steel-plastics composite pipe etc. must not all use welding and flanged joint, otherwise need after-treatment.
3. being conducive to construction safety
It is convenient using groove pipe fitting interconnection technique construction organization.Using welding and flanged joint, then need to be equipped with complexity
Feed cable, cutting implement, bonding machine and oxygen and acetylene gas bottle etc., this just brings complexity to construction organization, and also deposits
In the dangerous hidden danger of electric leakage and fire.Welding slag caused by welding simultaneously and gas cutting, inevitably falls into inside pipeline, makes
It easy tos produce pipeline valve member even equipment in block, also water quality in pollution pipe.
In addition, welding and flanged joint unavoidably need the working at height of prolonged high intensity, it is also easy to happen life
Produce safety accident.
4. system stability is good, groove pipe fitting connection type easy to maintenance has unique flexibility characteristics, and pipeline is made to have
Anti-vibration, anti-shrink and the ability of expansion, compared with welding with flanged joint, the stability of pipe-line system increases, and is more suitable for temperature
The variation of degree decreases destruction of the pipe stress to structural member to protect pipeline valve member.
Since groove pipe fitting attended operation is simple, required operating space becomes smaller, this brings perhaps for repair in the future
Multi-party note part.When pipeline needs repairing and replaces, only need to unclamp two panels clip can arbitrarily replace, rotate, changing one section
Pipeline.It is not required to destroy surrounding wall, reduces maintenance time and maintenance cost.
5. economic analysis：Groove pipe fitting attended operation is simple, saving of work and time, reduces breakthrough, therefore have good warp
Ji benefit.
