Abstract
The utility model relates to a valve accessory and aims to provide a single wing flow assignment board applied to butterfly valves for water system regulation. The single wing flow assignment board comprises a mounting plate which is provided with a mounting hole, the mounting plate is connected with a wing-shaped flow assignment board in broken line shape, and at least an flow assignment hole ispositioned on the wing flow assignment board. The single wing flow assignment board has the beneficial effects that the single wing flow assignment board can keep consistent with an all-purpose regulating seat valve which has the same specification, and the common butterfly valves with same size can obtain different through-flow capabilities through being provided with single wing flow assignmentboards with different specifications, thus the application is quite flexible, and a butterfly valve equipped with the single wing flow assignment board of the utility model has the regulating characteristic of equal percentage.
Description
Technical field
The utility model relates to a kind of valve fittings.More particularly, the utility model relates to a kind of single-blade port plate that is applied to the butterfly valve of water system adjusting.
Background technique
Butterfly valve is the modal a kind of control valve of water system, butterfly valve because of its have simple in structure, easy processing, easy for installation, through-current capability is big etc., and advantage is widely used in the various water systems.
But butterfly valve generally uses the occasion in some switching mode controls, mainly be because the control characteristic of itself is very poor, almost lose regulatory function more than 60% when butterfly valve is opened to, so butterfly valve do not pay attention to by people generally, become low taste switching mode valve cheap, that processing is coarse.
In the vehicular central air-conditioning system with hot and cold water, the adjusting of coil heat exchanger heat exchange quantity is to realize by the size that modulating valve changes water flow, generally adopts straight journey seat valve modulating valve to regulate at present.Defectives such as but straight journey seat valve modulating valve exists, and through-current capability is little, energy dissipation is serious, complex structure, price are high, and these advantages that butterfly valve had exactly.It promptly is that the utility model is related that the control characteristic of change butterfly valve makes its adjusting field that is applied to water system.In existing utility model patent port plate (CN2799999Y), its port plate structure is too complicated, is not easy to Practical Calculation and design, reduces the complexity of structure when the utility model will change the butterfly valve control characteristic.
Theoretical calculation and engineering practical application show, has the modulating valve of equal percent regulating characteristic in employing, can obtain high-quality heat exchange control, reduces system energy consumption, reduces the pipe network noise.
The model utility content
Main purpose of the present utility model is to overcome deficiency of the prior art, provides a kind of and can change the butterfly valve control characteristic, make butterfly valve have equal percentage control characteristic, be installed on the accessory on the butterfly valve butterfly plate---single-blade port plate.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model provides a kind of single-blade port plate, comprises mounting plate, establishes mounting hole on the mounting plate, and mounting plate is polyline shaped with a wing port plate and is connected, and establishes at least one assignment hole on the wing port plate.
As a kind of improvement, the described assignment hole that is positioned on the wing port plate be circular port, square opening or slotted eye wherein any one.
As a kind of improvement, establish mounting hole on the described mounting plate.
As a kind of improvement, the mounting plate of described single-blade port plate and wing port plate are to be formed by a whole material material bending.
As a kind of improvement, the mounting plate of described single-blade port plate and wing port plate are polyline shaped by being welded to connect.
Wing port plate is installed in the both sides of the butterfly plate of general butterfly valve in pairs by connecting screw, with the form a whole valve plate of form of butterfly plate, by the position of assignment hole on wing port plate and the combination of the area of wing port plate and designed assignment hole area, can adjust the control characteristic and the through-current capability of butterfly valve.
Compared with prior art, the beneficial effects of the utility model are:
1, the valve through-current capability that the butterfly valve of the utility model single-blade port plate is installed can be consistent with the universal adjusting seat valve of same size, and the common butterfly valve of same size can obtain different through-current capabilities by the single-blade port plate of configuration different size, uses very flexible;
2, the butterfly valve that the utility model single-blade port plate is installed has the control characteristic of equal percentage.
Description of drawings
Fig. 1 is the plan view of embodiment's midsetwing port plate;
Fig. 2 be among Fig. 1 A-A to sectional drawing;
Fig. 3 is a kind of scheme of installation;
Fig. 4 is another kind of scheme of installation;
Fig. 5 is a structural representation of using butterfly valve of the present utility model.
Embodiment
With reference to figures 1 through 5, will be described in detail the utility model below.
Attached Fig. 1 and 2 provides single-blade port plate 5, comprises mounting hole 1, mounting plate 2, assignment hole 3 and wing port plate 4; Assignment hole 3 is positioned on the wing port plate 4, and mounting hole 1 is positioned on the mounting plate 2, and mounting plate 2 is the broken line structure with wing port plate 4 and is connected.
The mounting type of single-blade port plate 5 is provided by accompanying drawing 3 and 4, a pair of single-blade port plate 5 is installed in the both sides of the butterfly plate 6 of general butterfly valve by connecting screw 7, with the form a whole valve plate of form of butterfly plate 6, by the position of assignment hole 3 on wing port plate 4 and the combination of the area of wing port plate 4 and designed assignment hole 3 areas, can adjust the control characteristic and the through-current capability of butterfly valve.A pair of single-blade port plate 5 can be butterfly plate axis symmetry according to mode shown in Figure 3 to be installed, and also can be the center line symmetry according to mode shown in Figure 4 and install.
Accompanying drawing 5 is for being equipped with the structural representation of butterfly valve of the present utility model, and test and data fitting find that butterfly valve of the present utility model is installed has equal percent regulating characteristic by experiment.
Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
