Description
One, technical field
The utility model relates to a kind of taper multifunction energy-saving valve, belongs to the gate valve field on the fluid delivery pipeline.
Two, background technique
At present, in the pipe-line system that liquids and gases are carried, adopting gate valve, check valve, modulating valve and water-hammer arrester is independently parts of difference, and finish different functions separately: gate valve is finished the function of complete shut-down, standard-sized sheet, also double as modulating valve usefulness in many systems, but the hydraulic resistance loss is big; Check valve prevents that current from swinging to mobilely, prevents to impact and makes the unit counter-rotating or produce displacement; Modulating valve plays hydraulic loss with minimum, finishes the adjusting of flow and pressure, satisfies the requirement of system condition; Water hammer or water attack canceller play slowly closes check valve, avoids pipe-line system to produce water hammer, destroys pipeline.Physical dimension increases like this, and the pipe-line system floor space increases, and it two is installation cost height, has increased construction investment; It three is that hydraulic resistance loss is big, and especially the check valve resistance coefficient is big, increases the operating cost expense; It four is that parts are many, increases maintenance load, or the like.
According to the problems referred to above, multifunctional control valve has appearred on the China market, their genus dishes or plate valve, barrier film pressure difference control mode, its complex structure, flow of fluid are not smooth, and the hydraulic resistance loss is big, deficiencys such as membrane life weak point.
Three, summary of the invention
The purpose of this utility model is to provide a kind of taper multifunction energy-saving valve at the deficiencies in the prior art.
Be provided with seal ring between the spool of taper multifunction energy-saving valve and the preceding valve gap, the spool afterbody contacts with the aperture eccentric wheel is movable, and the aperture eccentric wheel is fixed in the rotating shaft of valve opening and locking device, and locking device connects and composes integral body with the back valve gap.
In order better to realize goal of the invention, the utility model is also taked following technical measures:
Spool is a buoyancy type.
Valve opening is regulated and locking device is handle or motoring, and the rotating shaft that both connect worm screw, worm gear drives aperture eccentric wheel envoy energy threshold breakdown, close or spacing in a certain neutral position.
Installing pressure-flow sensor, pressure meter switch and pressure-flow measuring meter in the preceding valve gap.
Several pieces radial support stators of installing in the back valve gap, restriction spool moving linearly.Back valve gap is connected perforation by slip joint, modulating valve, one-way valve with preceding valve gap outward.
The utlity model has following advantage:
1, design is unique, and this valve can be finished four kinds of difference in functionalitys of gate valve, check valve, modulating valve and water-hammer arrester simultaneously.
2, liquid flows in pipeline basically in line, reduces greatly than the hydraulic resistance of gate valve, check valve.The resistance coefficient can fall more than 50%.Has tangible power savings advantages.
3, total geometrical length shortens, and quality alleviates greatly, economical with materials and reduction equipment cost.
4, current are through streamlined capitate hollow spool, and current are freely suitable, light weight, and the Push And Release reflection is sensitive, and the vibration, noise and the local cavitation that cause than gate valve are little.
5, the inlet of general valve is not provided with pressure gauge, and the utility model is provided with the pressure-flow correspondence table, makes things convenient for the user to measure.
6, the design has considered pressure, the flow size can scene and length of run control and demonstration.
7, structure length, flange specification, pressure test etc. meet standard GB 12221-89; GB/T17241.6-98.
Four, description of drawings
Fig. 1 is taper multifunction energy-saving valve arrangement figure.
Fig. 2 is a cut-away view.
1 pressure-flow measuring meter, 2 pressure-flow sensors, 3 anti-water hammer time delay devices, 4 slip joints, 5 modulating valve, 6 one-way valves, 7 handles, 8 motor, valve gap before 9,10 back valve gaps, 11 buoyancy type spools, 12 seal rings, 13 valve openings and locking device, 14 aperture eccentric wheels, 15 relieving devices, 16 dewatering orifices, 17 support stator, 18 pressure meter switches, 19 worm screws, 20 worm gears.
Five, embodiment
Below by embodiment the utility model is specifically described, but can not be interpreted as the utility model protection domain and restriction.
Taper multifunction energy-saving valve has simple in structure, easily manufactured, shown in Fig. 1～2, be provided with seal ring 12 between the spool 11 of energy-conservation valve and the preceding valve gap 9, spool 11 afterbodys with contact with aperture eccentric wheel 14 is movable, aperture eccentric wheel 14 is fixed in the rotating shaft of aperture adjusting and locking device 13, and locking device connects and composes integral body with back valve gap 10.Spool 11 is a buoyancy type.Aperture regulate and locking device be rotating shaft that handle 7 or motor 8 connect worm screws 19, worm gear 20 drive aperture eccentric wheel 14 envoys can opening of valves, close or spacing in a certain neutral position.Before installing pressure-flow sensors 2 in the valve gap 9 (do long-distance metering with), pressure meter switch 18 and pressure-flow measuring meter 1 (do scene with) be connected.Several pieces radial support stators 17 of installing in the back valve gap 10, back valve gap 10 outer slip joint 4, modulating valve 5, one-way valves 6 by anti-water hammer time delay device 3 are connected perforation with preceding valve gap 9, back valve gap 10 tops and bottom are respectively equipped with vent hole 15 and dewatering orifice 16, make things convenient for pipeline operation and maintenance.
Working principle of the present utility model is when pipe-line system need be closed, aperture is regulated and locking device 13 makes aperture eccentric wheel 14 major parts withstand the spool afterbody by the rotating shaft that artificial handle 7 or motor 8 drive worm screw 19, worm gear 20, and promptly the buoyancy type spool is in left position; When the pipe-line system operating mode needed a certain flow and pressure, artificial handle or motoring eccentric wheel 14 were in a certain position, open pressure meter switch, show flow, force value, and the fine setting aperture is till the flow that satisfies the operating mode demand, pressure; When system because of accident has a power failure suddenly, current reverse flow, spool and aperture eccentric wheel 14 are thrown off automatically to left, promptly close until valve to the closing direction motion.Simultaneously, a small gangs of current delay about 3～40 seconds of the shut-in time of spool by anti-water hammer time delay device recoil spool point mouth, have then reached the effect that prevents to weaken water hammer or water attack, improve the working life of energy-conservation valve.
