Embodiment
Referring to accompanying drawing, a kind of power-saving balanced valve, comprise valve body 1, piston cylinder 9, valve gap 12, valve rod 32, opening latch 15, only revolve guide way 17, Stem Mut 19, handwheel or electric actuator 21, gland nut 24, stuffing box packing 25, I-shaped spool 33, interlock latch 37 and guide and seal lobe 39, it is characterized in that:
Described power-saving balanced valve be designed to use the guide open the valve principle make produce between the chamber 34 under chamber 31, the piston cylinder on the piston cylinder on the piston cylinder 9 pressure reduction forming on the piston plate 6 that thrust, this thrust-balancing opposite with fluid medium pressure direction on the flap 41 have been eliminated the fluid medium pressure on the flap 41 equilibrium valve of realizing light open and close valve, the flow passage structure of the valve body 1 employing high in and low out of this power-saving balanced valve
Described valve gap 12 is the taper lid, this valve gap 12 is provided with stuffing box 13 and support 14, should go up in the stuffing box 13 stuffing box packing 25, valve rod 32, gland nut 24 were housed, support 14 is provided with guard rail 18, the inner chamber of valve gap 12 is provided with down stuffing box 11, be equipped with V-shaped ring 28, valve rod 32, preloading spring 26, back-up ring 27, gland 30 and gland nut 10 in this time stuffing box 11, valve gap 12 is connected with valve body 1 fitting tight by bolt 29.
Described V-shaped ring 28 is for having preloading spring 26 and hydrodynamic pressure to make V-shaped ring 28 produce the distortion mechanism in compensation V-shaped rings 28 and valve rod 2 wearing and tearing generation gaps automatically with fit sealing and the design of valve rod 32 and following stuffing box 11.
Described valve rod 32 is provided with screw thread, hinge last 23, guide and seals lobe 39, interlock hinge last 38, its upper end is equipped with and only revolves guide way 17, promptly opening latch 15 through only revolve on the guide way 17 to bore a hole 22, hinge last 23 on the valve rod 32 interts together and opening is fixed.The guiding groove 16 that only revolves guide way 17 two ends is assemblied on the guard rail 18 of support 14.Valve rod 32 upper ends connect with handwheel or electric actuator 21 by Stem Mut 19, lock nut 20, design interlock hinge last 38 is a Spielpassung with interlock latch 37, valve rod 32 lower ends are by interlock latch 37 and I-shaped spool 33 assembling interlocks, promptly adopt interlock latch 37 through the interlock on the connecting leg 5 of I-shaped spool 33 to bore a hole 2, the interlock hinge last 38 of valve rod 32 lower ends and realize being connected at annular groove 3 internal fixation with the activity of I-shaped spool 33 in the valve body 1 with shell ring 36;
Design has equalizing orifice 7 on the piston plate 6 of I-shaped spool 33, on piston plate 6 outer rims piston ring 8 is housed, on the flap 41 of I-shaped spool 33 design have guide's relief hole 40, the guide on the valve rod 32 seal lobe 39 can with guide's relief hole 40 outer rims touch mutually the sealing and separate pressure release.
Only revolve guide way 17 by opening latch 15 through only revolve on the guide way 17 to bore a hole 22, hinge last 23 on the valve rod 32 inserts after-openings and fixedly is assembled together.Only revolve that both sides guiding groove 16 is enclosed within the guard rail 18 on the guide way 17, realized only revolving location and guide function when valve rod 32 open and close valve position are moved.
Interlock hinge last 38 on the valve rod 32 can drive I-shaped spool 33 by interlock latch 37 and make open and close valve position shifting movement, can be implemented in flowing medium ultra low pressure, pressure-less state and drive I-shaped spool 33 upper and lower motions pressure open and close valves down.
Piston ring 8 and V-shaped ring 28 all adopt the very little made of friction ractor, therefore, piston ring 8 and piston cylinder 9, frictional resistance is very little between V-shaped ring 28 in the following stuffing box 11 and the valve rod 32, therefore the operational torque of valve rod 32 can reduce greatly, not only make rapid operation, and prolong the working life of product greatly.V-shaped ring 28 causes loss can utilize preloading spring elastic force and fluid medium pressure acting in conjunction to make it produce distortion with valve rod 32 frictions, automatic compensate for wear gap, can realize V-shaped ring 28 all the time with valve rod 32 and 11 applyings of following stuffing box, guarantee that long-term the use all can keep valve rod 32 excellent sealing performance and steering capability, leaks energy saving thereby can effectively stop packing.
Stuffing box packing 25 in the last sealed letter 13 is when V-shaped ring 28 proper functioning, needn't apply precompression and implement sealing function, only when the excessive appearance of V-shaped ring 28 wear extenies is leaked, just compress and realize the secondary seal function by gland nut 24, thereby effectively prevent the leakage of packing, realize energy saving.
Because it is very little that the guide seals lobe 39 areas, hydrodynamic pressure can be ignored to its influence, basically the frictional resistance that has only V-shaped ring 28 and threaded stem and Stem Mut 19 to be produced during valve rod 32 rotations, during the open and close valve I-shaped spool 33 flap 41 on be not subjected to the fluid medium pressure effect, the operational torque of handwheel or electric actuator 21 is just very little like this, greatly alleviate operator's labor intensity or reduced the electric actuator power consumpiton, thereby realized energy saving.
This energy-conservation equilibrium valve working procedure is as follows:
One, open the valve process: this energy-conservation equilibrium valve adopts the guide to open the valve principle, when valve is opened the valve operation by close valve state, flowing medium enters valve body 1 from valve inlet 35, driving Stem Mut 19 by rotation hand wheel or electric actuator 21 rotates, making the guide of valve rod 32 lower ends seal lobe 39 separates with guide's relief hole 40 outer rims, the fluid of chamber 31 flows to valve export 4 by guide's relief hole 40 on the piston cylinder, the hydrodynamic pressure of chamber 31 reduces rapidly up to the pressure that equals valve export 4 on the piston cylinder, and the fluid medium pressure of chamber 34 acts on the also corresponding increase of thrust on the piston plate under the piston cylinder, when this thrust acts on the gravity of pressure on the flap 41 and I-shaped spool 33 and frictional resistance more than or equal to fluid during sum, I-shaped spool 33 moves upward, thereby Open valve, rotation hand wheel or electric actuator 21 can drive valve rod 32 generations by Stem Mut 19 and open, closing valve displacement movement, valve rod 32 drive interlock latch 37 by interlock hinge last 38 makes I-shaped spool 33 come the controlling opening of valve size with valve rod 32 interlock displacements.
Two, close the valve process: when valve when opening the valve state and close the valve operation, flowing medium enters valve body 1 from valve inlet 35 and flows out through valve export 4, when handwheel or 19 rotations of electric actuator 21 rotating band ovable valve stem nuts, drive valve rod 32, I-shaped spool 33 produces displacement and closes valve, flap 41 throttle downs on I-shaped spool 33, the guide seals lobe 39 and closes guide's relief hole 40, since on the piston cylinder under chamber 31 and the piston cylinder chamber 34 have equalizing orifice 7 to communicate, on this moment piston cylinder under chamber 31 and the piston cylinder pressure difference of chamber 34 be zero, be in state of equilibrium, piston plate 5 stress balances, valve is in closed condition, has realized the purpose of the power-saving balanced valve of the utility model.
In sum, it is laborsaving that this energy-conservation balanced valve has the open and close valve, and sealing part abrasion auto-compensation, steering capability are good, the characteristics such as sealing property is good, long service life energy savings.
