Abstract
The utility model discloses a novel high-pressure regulating valve. The novel high-pressure regulating valve comprises a valve body, wherein the valve body is provided with a valve cavity, the valve cavity is provided with a valve rod, and the valve body is provided with a medium flow in channel and a medium flow out channel. The novel high-pressure regulating valve is characterized by further comprising a first valve element and a second valve element, wherein the first valve element is provided with an inner cavity and a first through hole which enables the inner cavity and the medium flow out channel to be communicated, a sleeve valve cage is arranged outside the first valve element, the sleeve valve cage is provided with a second through hole which is communicated with the medium flow in channel, the first valve element is provided with a second through hole which is communicated with the inner cavity, the second valve element is arranged inside the inner cavity and is in linkage with the valve rod, the valve rod drives the second valve element to move up and down to achieve communication and blocking between the inner cavity and the medium flow out channel, the second valve element drives the first valve element to move up and down to achieve communication or blocking between the medium flow in channel and the inner cavity, an opening is arranged at the position, corresponding to the upper portion of the second valve element, of the first valve element, and a valve element pressing cover is arranged on the opening. Opening and closing of the novel high-pressure regulating valve can be controlled conveniently under the condition of high pressure difference.
Description
Technical field
The utility model relates to a kind of novel high-pressure modulating valve.
Background technique
In the prior art, there is following drawback in the structure of modulating valve, and when the medium flow channel of the valve body of flowing through, medium flow out in the poor larger situation of channel pressure, there is unbalanced problem in the spool pressure at both sides, and this problem causes valve rod to drive comparatively difficulty easily.
The model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of novel high-pressure modulating valve is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel high-pressure modulating valve comprises valve body (A), and it has valve pocket (A1), and described valve pocket is provided with valve rod (A2), and described valve body is provided with medium flow channel (A3) and medium flow pass (A4), it is characterized in that, also comprises:
The first spool (B), it has inner chamber (B1), the first spool is provided with first through hole (B2) of conducting inner chamber (B1) and medium flow pass, the first spool is provided with telescoping valve cage (B3) outward, described sleeve valve cage is provided with the second through hole (B4) with the flow channel conducting, and the first spool is provided with the second through hole (B5) that communicates with inner chamber (B1);
The second spool (C), it is arranged in the inner chamber (B1) and with valve rod and links; Wherein,
Described valve rod drives the second spool and moves up and down and realize conducting and the cut-off of inner chamber and medium flow pass, described the second spool drives the first spool and moves up and down and realize conducting or the cut-off of medium flow channel and inner chamber, corresponding the second spool top position of described the first spool is provided with opening (D), is positioned at opening (D) and is provided with spool gland (E).
The beneficial effects of the utility model are: the utility model can make things convenient for the open and close of regulating and controlling valve under the High Pressure Difference condition.
