Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] like Figure 1-4 As shown, the three-stage perforated spool regulating valve described in the embodiment of the present invention includes a valve body 1, a valve seat 2, a throttle sleeve 3, a valve cover 4, and an integrally formed valve core 5 and valve stem 6. The valve core 5 and the valve seat 2 are arranged in the throttle sleeve 3, the lower part of the valve core 5 is connected with the valve seat 2, the valve stem 6 is connected with the valve...

The invention relates to a three-stage perforating valve element adjusting valve. The three-stage perforating valve element adjusting valve comprises a valve body, valve bases, a throttle sleeve, a valve cover, and a valve element and a valve rod integrally molded; the valve element and the valve bases are arranged in the throttle sleeve; the lower part of the valve element is connected with the valve bases; the valve rod is connected with the valve cover; the valve bases are provided with multiple valve base holes for passing through a fluid; the valve element is provided with multiple valve element holes for passing through the fluid; and the valve bases, the valve element and the throttle sleeve form a fluid channel. The three-stage perforating valve element adjusting valve has the following beneficial effects: based on a multistage pressure reducing principle, the valve element is perforated; and the valve bases as many as the valve element holes and matched with the valve element holes are arranged in the throttle sleeve, so that the fluid can reduce the pressure by degrees, the equipment damage caused by the caviation and flash evaporation phenomenon in high-pressure difference of the fluid is prevented, and the service life of the adjusting valve is prolonged.
Description
technical field [0001] The invention relates to a three-stage perforated spool regulating valve. Background technique [0002] China is a country with a large energy source, and the use of regulating valves under high working conditions is becoming more and more widespread, especially in the occasions of high pressure difference and anti-cavitation, but these regulating valves used under high working conditions are basically monopolized by foreign countries. The research and development of this aspect is relatively lagging behind, and there is no independent product. [0003] At present, the regulating valves used in China are mainly in the form of a simple single seat. Although this method can accurately adjust the pressure, the valve seat of the porous valve trim can play a guiding role, and the vibration resistance is better. Porous spool (optional 1st, 2nd or 3rd) has better pressure reduction and noise reduction effects, especially suitable for gaseous media. When the...
