Abstract
The utility model relates to a valve, in particular to a replaceable restriction orifice used for an air control valve. The restriction orifice is arranged at an air port inside a flange of one side of a valve body, and a clamp spring is arranged outside the restriction orifice. A group of regular round holes in a fixed restriction orifice can effectively damp the pressure of compressed air and can play a function of rectification, and on the basis of the fixed restriction orifice, according to a show value of a pressure gage arranged on a pressure port, the replaceable restriction orifice can be replaced based on the actual requirement of adjusting pressure range. By the aid of the replaceable restriction orifice used for the air control valve, invariance of flow characteristic of a common control valve is overcome.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of Changable type restriction orifice for air-regulating valve.
Background technique
Aircraft wind-tunnel test site and with the place of pressurized air as power source, need to do accurate the adjustment to the flow of high pressure air, changes in flow rate is frequent, the scope of pressure, changes in flow rate is large, and the zero leakage under requiring in off position.The fixed flow-limiting orifice plate can not be accomplished control to flow, and it is very inconvenient to change valve to the adjustment of flow.
The model utility content
The utility model provides a kind of Changable type restriction orifice for air-regulating valve for the problems referred to above
The utility model adopts following technological scheme:
A kind of Changable type restriction orifice for air-regulating valve described in the utility model comprises restriction orifice, jump ring; Described restriction orifice is arranged in gas port place in valve body one side flange, and jump ring is arranged in the restriction orifice outside.
Beneficial effect
A kind of Changable type restriction orifice for air-regulating valve that the utility model provides, can effectively decay compressed-air actuated pressure and can play the effect of rectification of one group of rule circular hole in the fixed flow-limiting orifice plate, the restriction orifice of Changable type is on the basis that has equally the effect of fixed flow-limiting orifice plate, can be according to the manometric show value of putting on the pressure-taking hole, the needs of adjusting pressure range are according to actual needs changed.Overcome the immutableness of the Flow characteristics of common modulating valve.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is flange among the figure, the 2nd, and restriction orifice, the 3rd, jump ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure: a kind of Changable type restriction orifice for air-regulating valve comprises restriction orifice 2, jump ring 3; Described restriction orifice 2 is arranged in valve body one side flange 1 interior gas port place, and jump ring 3 is arranged in restriction orifice 2 outsides.
Claims (1)
1. a Changable type restriction orifice that is used for air-regulating valve is characterized in that: comprise restriction orifice (2), jump ring (3); Described restriction orifice (2) is arranged in the interior gas port of valve body one side flange (1) place, and jump ring (3) is arranged in restriction orifice (2) outside.
