Abstract
The utility model discloses an adjustable restriction orifice. Throttling discs are arranged in counter bores of two clamping flanges, through-holes are formed on the throttling discs and two clamping flanges, when mounting on a fluid pipeline, and the through-holes on the throttling discs and two clamping flanges and holes of the fluid pipeline are mutually eccentric. In the utility model, two circular channels with an eccentricity E of the axis of the pipeline are opened on two clamping flanges and the throttling discs and coincide when in primary assembly, and at the moment, the circulation area is the area of a circle and the maximum circulation area. The utility model provides an adjustable restriction orifice for a pipeline which only needs to roughly adjust the fluid parameters, such as flow rate, pressure, temperature, and so on. The adjustable restriction orifice has the advantages of simple structure and low price, and can greatly lower the engineering cost because of replacing a control valve in the applicable fluid pipeline.
Description
Technical field
The utility model belongs to a kind of simple and easy regulating valve, is to be applied in to play coarse adjustment fluid flow, pressure, the isoparametric a kind of device of temperature in the fluid circuit.
Background technique
In fluid circuit, convection cell parameter such as flow, pressure, temperature etc. are regulated if desired, will adopt modulating valve; Sometimes only require that the convection cell parameter carries out rough adjusting, adopt numerous and diverse and expensive modulating valve this moment, will significantly raise the cost.
Summary of the invention
The utility model provides a kind of adjustable restricting orifice for solving the problem that prior art exists
A kind of adjustable restricting orifice is characterized in that, the throttling dish is arranged in the counterbore of two clamping flanges, and throttling dish and two clamping flanges are provided with through hole; When being installed on the fluid pipe-line, the through hole on throttling dish and two clamping flanges and the hole of fluid pipe-line are eccentric mutually.
Have the circular channel that has throw of eccentric E with pipeline axis on two clamping flanges of the utility model and the throttling dish, and when assembling just two circular channels are overlapped, this moment, circulation area was the area of circle, also was the maximum flow area.
For adjusting, can on the bolt between two clamping flanges, be set with distance sink tube; The elasticity that the length decision throttling dish of distance sink tube is regulated.On the circumference of throttling dish, can have driving hole.
The utility model for only need the convection cell parameter as: the pipeline that flow, pressure, temperature etc. are carried out coarse adjustment provides a kind of adjustable restricting orifice.Because it is simple in structure, cheap that adjustable restricting orifice has, alternative modulating valve in its fluid pipe-line that is suitable for, thereby can reduce engineering cost significantly.Under the situation of satisfying the demand, the utility model can significantly be reduced expenses.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 3 is the A-A sectional view of Fig. 1
1 clamping flange, 2 throttling dishes, 3O RunddichtringO, 4 bolts, 5 distance sink tubes, 6 nuts, 7 are adjusted spanners, 8. flange 9 through holes, 10 pipelines, 11 driving holes.
Embodiment
A kind of adjustable restricting orifice, throttling dish 2 are arranged in the counterbore of two clamping flanges 1, and throttling dish and two clamping flanges are provided with through hole 9; When being installed on the fluid pipe-line 10, the through hole 9 on throttling dish and two clamping flanges is eccentric mutually with the hole of fluid pipe-line 10; Between described clamping flange and throttling dish, be provided with O RunddichtringO 3 with anti-leak.Throttling dish and two clamping flanges are fastening by bolt 4 and nut 6; On the bolt between two clamping flanges 4, be set with distance sink tube 5; On the circumference of throttling dish, have driving hole 11.
During installation, the throttling dish is loaded in the counterbore of two clamping flanges, two O seal rings is loaded in the O RunddichtringO groove of throttling dish again, other joins two standard pipeline flanges 8 that are connected with exterior tubing 10, tightens together shown in accompanying drawing 1 with screw bolt and nut; Between two clamping flanges, be with distance sink tube on the bolt, the length of distance sink tube will be matched, and makes assembling back product suitable in the moment of regulating the time flow table, and guarantees that the sealing of O RunddichtringO is reliable.After assembling was finished, the fastening piece of outwarding winding removed two standard flanges, each part was connected or auxiliary package separately again.
During adjustment, subsidiary adjustment spanner 7 one ends are inserted driving hole 11, rotate the throttling dish, it is rotated a certain angle around the O point, see accompanying drawing 3; Because passage 9 is eccentric openings, the throttling dish rotates, the original circular channel that overlaps of clamping flange and throttling dish certain angle that will stagger, the cross section of two port holes will form new circulation area, throttling disc spins angle difference, corresponding the changing of circulation area meeting, so circulation area has adjustability.
Claims (3)
1. an adjustable restricting orifice is characterized in that, the throttling dish is arranged in the counterbore of two clamping flanges, and throttling dish and two clamping flanges are provided with through hole; When being installed on the fluid pipe-line, the through hole on throttling dish and two clamping flanges and the hole of fluid pipe-line are eccentric mutually; Throttling dish and two clamping flanges are fastening by screw bolt and nut.
2. according to the described adjustable restricting orifice of claim 1, it is characterized in that, on the bolt between two clamping flanges, be set with distance sink tube; On the circumference of throttling dish, have driving hole.
