Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0029] Such as Figure 1-Figure 3 As shown, a spool of this embodiment includes a spool body 10, the spool body 10 includes a large-diameter section and small-diameter sections 20 located on both sides of the large-diameter section, between the small-diameter section 20 and the large-diameter section A stepped end surface 30 is formed.
[0030] In this embodiment, the spool body 10 is provided with an axially penetrating spool hole 50, and a throttling tube 40 is installed in the spool hole 50, and the throttle tube 40 is provided with an axially penetrating throttling hole 41. . Usually, the di...

Abstract
The invention relates to a valve element used by a throttle valve and a valve element manufacturing method. The valve element comprises a valve element body, wherein the valve element body is providedwith an axial cut-through valve element hole; a throttle pipe is mounted in the valve element hole; and the throttle pipe is provided with an axial cut-through throttle hole. According to the valve element and the valve element manufacturing method, on the basis of the condition that the aperture of the throttle hole is abnormally small, the valve element hole can be machined into a conventionalhole with a relatively large aperture, the machining of the conventional hole does not have process difficulty, the throttle holes of conventional throttle valve elements in the prior art are machinedthrough a conventional drilling-reaming combined manner, even the aperture of the throttle hole of the throttle pipe is relatively small, small-aperture metal pipes suck as needles and the like can be purchased on the market and the problem of machining difficulty also does not exist, and through mounting the throttle pipe in the valve element hole, the manufacturing of throttle valves with abnormally small apertures is solved, so that the technical advantages of being simple in structure and low in manufacture cost are provided.
Description
technical field [0001] The invention relates to a valve core used in a throttle valve and a manufacturing method of the valve core. Background technique [0002] In the throttle valve spool in the prior art, the throttle hole on the spool is processed by first drilling and then reaming on the spool body. However, when the diameter of the spool and the orifice of the spool becomes smaller and smaller, for example, the diameter of the orifice is required to be 0.5 mm or less, the conventional processing method of drilling first and then reaming will be difficult to carry out, although it can It can be realized by a high-precision machining center, but its production cost will increase a lot, and its industrial practicability is not strong. Therefore, it is necessary to improve the structure and manufacturing method of the existing small-sized throttle valve core. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the ...
