Problems solved by technology

However, this kind of throttle opening has a long throttle flow channel, which forms a long gap-like flow channel at low flow rates, and impurities are easy to block the throttle opening, so that a smaller minimum regulated flow rate cannot be obtained.
Moreover, the structure of this multi-stage cone valve type throttle is more complicated, the processing is more difficult, and the accuracy is difficult to guarantee

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, the present invention is equipped with a valve sleeve 15 at the center of the valve body 14, and the lower end of the valve body 14 and a side are respectively provided with a water inlet A and a water outlet B, and the water inlet A at the lower end of the valve body 14 passes through the lower end hole of the valve sleeve 15 and a side surface. The hole communicates with the water outlet B on one side of the valve body 14; the valve body 14 is equipped with a flange 1, the throttle spool 5 is installed in the valve body 14 and the flange 1, and the lower end of the throttle spool 5 is provided with an axial triangular connection. The throttling valve port of the slot E is matched with the valve sleeve 15, and the oblique pressure balance hole C is opened in the middle shaft of the throttle spool 5 and is matched with the hole of the flange 1, and the throttle spool 5 outside the flange 1 is installed There is an adjustment hand ...

Abstract

This invention publicized one kind of axial triangle to pass the trough type pure water hydraulic pressure throttle valve. It is loaded with the valve casing among the valve body, the valve body lower extremity and a side separately opens has the water inlet well valve casing lower extremity hole and a side face, Yu Fati a side water outlet connects; On the valve body is loaded with the flange, the throttle valve core installs in the valve body, in the flange, under the throttle valve core separates has the axial triangle to pass the trough the throttle valve port and to the valve casing coordination, outside on the flange throttle valve core is loaded with adjusts the handwheel, the flange upper extreme is loaded with the compression nut. This invention uses the axial triangle to pass the trough -like throttle valve port form, may realize the micro adjustment; In the structure uses increases the valve casing the mushroom valve structural style, may realize zero to divulge; Uses the O seal packing collar to add the elastic ring and the U seal skeleton adds the elastic ring safely the seal form, the seal is reliable, suits works under the center high pressure aqueous medium environment.

Description

technical field [0001] The invention relates to a flow control valve, in particular to an axial triangular channel type pure water hydraulic throttle valve. Background technique [0002] Pure water hydraulic technology directly replaces mineral oil with filtered natural water as the working medium of the hydraulic system without any additives, and has the unique advantages of wide sources, environmental friendliness, cleanliness and safety. The technical advantages demonstrated by the application of pure water hydraulic technology are conducive to sustainable development and the implementation of green manufacturing, especially in industrial sectors and technical fields that require hygiene, environmental protection and fire protection. The United States, Japan, Britain, Finland, Germany and Denmark began to develop it in the 1970s or early 1980s, and now it has entered the stage of practical promotion. Since the 1990s in my country, the research work on pure water hydrauli...
