Abstract
The utility model discloses a throttling core which comprises a core body, wherein the core body is in a columnar shape; the center of the core body has a through throttling hole; the throttling hole comprises a straight body hole section and a taper hole section; one end with large area of the taper hole is communicated with the straight body hole; and the straight body hole section is in arc transition with the taper hole section. The throttling core is made of ceramics or glass material, formed through simple abrasive machining, simple and stable in structure, and good in throttling effect, and is wear-resistant.
Description
Technical field
The utility model relates to a kind of throttling core.
Background technique
In pneumatic element, throttle valve is the most frequently used a kind of pneumatic element, and structural type is also numerous and complicated numerous, but wherein most throttle valve are all that size by restriction in modulating valve realizes flow control.Throttle valve service time of a specified duration after, valve easily weares and teares, and deviation can appear in actual flow and preset flow, thereby makes the outlet of valve body can not obtain the pressurized air of relatively stable flow, and throttle valve is unfavorable for being placed in the parts that only have small space owing to all having suitable volume.
Summary of the invention
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides a kind of throttling core that omits valve, directly realizes gas throttling by controlling the throttle orifice size.
The utility model is achieved through the following technical solutions:
A kind of throttling core comprises core body, and described core body is bar shape, and the core body center offers throttle orifice; Described throttle orifice comprises straight body hole section and tapered hole section; The larger end of described tapered hole area is connected with straight body hole and communicates; Arc transition between described straight body hole section and tapered hole section.
Described throttling core matter is pottery or glass.
The utility model compared with the prior art, simple and practical, by machining grinding throttle orifice tapered hole end, thereby the size in adjustment throttle orifice aperture realizes the purpose of throttling, and the utility model adopts pottery or glass as raw material, changes insensitive, wear-resistant to temperature, humidity, intensity is good, thus stability of flow.Because the taper hole tapering is little, to control therefore can reach without the section preset flow by simple cutting, the control of its flow velocity can realize increasing progressively with 0.1%.
Description of drawings
Fig. 1 is longitudinal sectional view of the present utility model.
In figure: 1-core body, 2-throttle orifice, the straight body of 21-hole, 22-tapered hole.
Embodiment
Understanding for the ease of those skilled in the art is described in further detail the utility model below in conjunction with accompanying drawing.Should be pointed out that specific embodiment described herein only is used for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of throttling core comprises core body 1, and described core body 1 is bar shape, and core body 1 center offers throttle orifice 2; Described throttle orifice comprises straight body hole section and tapered hole section; The larger end of described tapered hole 22 areas is connected with straight body hole 21 and communicates; Arc transition between described straight body hole section and tapered hole section.
Described throttling core matter is pottery or glass, and the manufacturing process by pottery or glass makes semi-finished product, then obtains accurate throttling core by machining.Detect the flow of throttling core, grinding throttling core tapered hole end, thus adjust the aperture size, reach the effect of adjust flux.Because the taper hole tapering is little, to control therefore can reach without the section preset flow by simple cutting, the control of its flow velocity can realize increasing progressively with 0.1%
The utility model throttling core matter also can adopt other chemical inertnesses, have material suitable hardness, stable physical property.
The content of mentioning in above-described embodiment is not to be to restriction of the present utility model, and under the prerequisite that does not break away from inventive concept of the present utility model, any apparent replacement is all within protection domain of the present utility model.
