Abstract
A double-acting balancing valve for fluid regulation and pipe network balance comprises a valve body, wherein an upper cover is mounted at the upper part of the valve body, a drain outlet is formed at the lower part of the valve body, a valve shaft A is mounted at the center of the upper cover, a valve shaft B is mounted in the valve shaft A, a valve clack A is mounted at the lower part of the valve shaft A, and a valve clack B is mounted at the lower part of the valve shaft B. The double-acting balancing valve can work together with a pressure gauge or a differential pressure gauge to obtain the required flow. Compared with the prior art, the double-acting balancing valve has more reasonable and compact structure and smaller volume, and is easy and convenient to disassemble and maintain and easy to master; and the double-acting balancing valve dispenses with special intelligent instruments for use and debugging, and the use and debugging are simple and convenient, so that the commissioning cost is reduced.
Description
Technical field
The utility model relates to a kind of two dynamic balancing valves of fluid regulation that are used for.
Background technique
In the system of fluid transmission ﹠ distribution such as heat supply, air-conditioning, need the flow of the distributing fluids of balanced and reasonable, people have invented the valve of many fluid regulation, wherein announce a kind of equilibrium valve patent in September, 1988, and notification number CN88203650 discloses a kind of equilibrium valve.This valve comprises valve body, flap and intelligent instrument etc.This valve can regulated fluid flow, but it must debug with intelligent instrument specially for same, general personnel are difficult to grasp, and apply inconvenience, using effect is not obvious.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of easy-to-use, tangible equilibrium valve of effect simple and convenient and easy to study is provided, we are called two dynamic balancing valves.
Summary of the invention
For the use complexity that overcomes existing equilibrium valve, the defective that degree of regulation is not high, the invention provides a kind of easy to use, two dynamic balancing valves that applicability is strong, the central heating system of very suitable China.
The utility model solves its technical problem and is achieved in that the loam cake upper surface is equipped with dial, and valve shaft A is equipped with at the loam cake center, and valve shaft B is housed among the valve shaft A; Valve shaft A bottom is provided with flap A, and valve shaft A passes loam cake, and exposed parts is equipped with pointer and locking device, and the pointed dial can show the relative position of flap A and valve port A; Be provided with screw rod in valve shaft B bottom, flap B is housed on the screw rod, flap B is relative with valve port B; Between flap A and the flap B in the radial position relative fixed; Valve shaft A and valve shaft B can rotate simultaneously, change the relative position of flap A and valve port A, also can rotate valve shaft B separately, change the relative position of flap B and valve port B.
Valve body lower portion is provided with sewage draining exit, can be connected with plug, drain pipe.
Flap A bottom is the spiral end-face structure, and flap B is the sleeve type structure.
Spool of the present utility model is two cover controlling devices, and is provided with sewage draining exit bottom the valve body, has solved China's heating network debugging complexity, and has needed adjusting instrument to cooperate the problem of valve demolition and maintenance difficulty.Compared with the prior art more reasonable structure, compactness, volume is little, dismounting, safeguards simply, and adjustment method such as is easy to grasp and popularizes at characteristics.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is an embodiment's of the utility model a structural representation;
Among the figure: 1. valve body, 2. loam cake, 3. dial, 4. locking device, 5. valve shaft B, 6. valve shaft A, 7. pointer, 8. pressure-taking hole A, 9. valve port B, 10. flap B, 11. sewage draining exits, 12. valve port A, 13. flap A, 14. pressure-taking hole B.
Embodiment
The fluid that enters valve along the direction of arrow among Fig. 1 produces twice pressure drop through valve port B (9), flap B (10), flap A, valve port A, by regulating the relative position of valve port B (9) and flap B (10), regulate the relative position of flap A and valve port A simultaneously, cooperate pressure gauge differential pressure meter to regulate pipeline flow.
Two dynamic balancing valves are when using mode, the high voltage terminal of pressure gauge differential pressure meter is linked to pressure-taking hole A (8), low voltage terminal is connected to pressure-taking hole B (14), and rotary valve shaft A (6) is with a certain scale of pointer (7) aligning dial (3), unscrew locking device (4) again, separately rotary valve shaft B (5) observes pressure gauge differential pressure meter, make the pressure reduction indicating value reach desirable value after, fastening locking device (4) is finished debugging.
Claims (3)
1. a two dynamic balancing valve comprises valve body, and loam cake is housed on the valve body, and it is characterized in that: the loam cake upper surface is equipped with dial, and valve shaft A is equipped with at the loam cake center, and valve shaft B is housed among the valve shaft A; Valve shaft A bottom is provided with flap A, and valve shaft A passes loam cake, and exposed parts is equipped with pointer and locking device, and the pointed dial can show the relative position of flap A and valve port A; Be provided with screw rod in valve shaft B bottom, flap B is housed on the screw rod, flap B is relative with valve port B; Between flap A and the flap B in the radial position relative fixed; Valve shaft A and valve shaft B can rotate simultaneously, change the relative position of flap A and valve port A, also can rotate valve shaft B separately, change the relative position of flap B and valve port B.
