Description
Technical field
This utility model relates to a kind of valve, is specifically related to a kind of flow measuring and controlling balanced valve.
Background technology
Hydraulic misadjustment is that present in pipe network system, essence is asked in current central air-conditioning, central heating or water treatment centers
Topic, thus causes indoor uneven in temperature, degree of comfort decreased, the little temperature difference of big flow, the Universal Problems such as energy consumption is high.And solve
Certainly hydraulic misadjustment problem it is crucial that waterpower debugging efforts.
Traditional static balancing valve is a kind of to flow through the flow resistance of valve to reach to regulate flow purpose by change
Balanced valve.Professional and technical personnel utilizes special intelligence instrument to debug, according to the model of valve, opening value and the pressure recorded
Difference signal flows through the flow value of this balanced valve and reaches setting value.But, owing to pipe network system inner valve is large number of, Er Qiexu
To regulate at any time, every time one valve of regulation, the flow of other valves the most all changes, and the workload of manual adjustment is big and nothing
Method eradicates hydraulic misadjustment.
Although the dynamic flow that the High-Precision Dynamic Flow Balancing Valve on market can realize pipe network system controls, but there is also
Following weak point: (1) not all occasions is required for realizing high-precision automatic flow and controls, and tells somebody what one's real intentions are in a lot of regulation and control frequencies
Use occasion such as use autocontrol valve, use cost will be greatly promoted；(2) service life is the shortest, particularly machinery pressure
The easy fatigue damage of thin film membrane in difference balance controller；(3) motility and bad adaptability, puts down for flow controllable type
Weighing apparatus valve operting differential pressure starting point is higher, and this is also waste energy consumption；(4) manufacture of spool machining is complicated, it is many to be not suitable for small lot
The production of kind.
Based on above-mentioned deficiency, traditional static balancing valve is used to seem to can be adapted to low cost and answering without frequently regulation
Use scene.But, there is again the regulation problem causing hydraulic misadjustment not in place in traditional static balancing valve.Meanwhile, the tune of valve
Joint will cause flow to change, it is impossible to will be unable to fundamentally solve hydraulic misadjustment problem if quantitative accurate regulation.
Therefore it provides a kind of with low cost and the static balancing valve of flow can be precisely controlled, it appears particularly necessary.
Utility model is held
Main purpose of the present utility model is to overcome deficiency of the prior art, it is provided that a kind of flow measuring and controlling balanced valve.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
This utility model provides a kind of flow measuring and controlling balanced valve, including valve body and the method being positioned at valve body two ends of hollow
Orchid, valve core structure is positioned at valve body, and manually regulation parts are connected with valve core structure by valve rod；Valve body in valve core structure both sides
On respectively set a tracting pressuring hole, an effusion meter is respectively connected to described tracting pressuring hole by two pressure guiding pipes.
As improvement, described effusion meter is pointer-type effusion meter, or electronic flowmeter.
As improvement, described valve core structure is the valve core structure of any one valve following: telescoping valve, butterfly valve, seat valve or
Ball valve.
As improvement, described effusion meter is connected with pressure guiding pipe one end by screw thread；The other end of described pressure guiding pipe and impulse
Hole connects.
Compared with prior art, this utility model has the beneficial effects that:
1, product structure technique is simple, operting differential pressure initiates that working value is little, through-current capability is big, control accuracy is high, use the longevity
Life length, low cost of manufacture, overall price/performance ratio are high, are suitable for small lot multi-item production.
2, the constant flow that can be widely applied to the flowings of various fluids such as central air-conditioning, central heating, water treatment centers controls
Application scenario.
3, product possesses and is better than linear discharge characteristic, can immediately obtain data on flows, be precisely controlled regulation action.
4, product possesses the instruction of accurate aperture and aperture lock function.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation of flow measuring and controlling balanced valve and installation diagram in this utility model embodiment.
Symbol in legend: 1 valve body, 2 valve core structures, 3 valve rods, 4 handwheels, 5 flanges, 6 effusion meters, 7 pressure guiding pipes, 8 tracting pressuring holes,
9 sealing gaskets, 10 bolts, 11 pipelines.
Detailed description of the invention
With reference to accompanying drawing 1, this utility model will be described in detail below.
Fig. 1 gives a kind of flow measuring and controlling balanced valve.This flow measuring and controlling balanced valve is to fill by the way of Flange joint
In the middle of the pipeline 11, including the valve body 1 of hollow be positioned at the flange 5 at valve body two ends, valve core structure 2 is positioned at valve body 1, manually
Regulation parts (handwheel 4) is connected with valve core structure 2 by valve rod 3；The valve body 1 of valve core structure 2 both sides respectively sets an impulse
Hole 8 (upper position at valve body 1 two ends in Fig. 1), an effusion meter 6 is respectively connected to described tracting pressuring hole 8 by two pressure guiding pipes 7.
In the present embodiment, effusion meter 6 and pressure guiding pipe 7 realize being connected by screw thread, screw thread respectively with effusion meter 6 and pressure guiding pipe 7 phase
Connect.
Wherein, effusion meter can use pointer-type effusion meter, it is also possible to is electronic flowmeter；Read for operator
Instant data on flows.Valve core structure 2 is the valve core structure of any one valve following: telescoping valve, butterfly valve, seat valve or ball valve,
Considering from Flow-rate adjustment precision, seat valve is optimal selection.Handwheel 4 uses the digital hand wheel that can show current valve aperture,
Its surface is provided with digital displaying window.By setting and the lock operation of the aperture locking mechanism of handwheel, prevent maloperation from causing
Flow changes.
The using method of flow measuring and controlling balanced valve:
First, check the design discharge value of each waterpower end, or confirm demand value according to load area and power consumption；
Then look at the meter readings on flow measuring and controlling balanced valve；Valve opening is adjusted, until meter readings reaches to need
Evaluation；Last fixed valve aperture.Now complete Flow-rate adjustment, it is achieved hydraulic equilibrium or flow restriction, reach energy-conservation purpose.
Obviously, this utility model is not limited to above example, it is also possible to have many deformation.Those of ordinary skill in the art
The all deformation can directly derived from this utility model disclosure or associate, are all considered as protection of the present utility model
Scope.
