Problems solved by technology

[0004] At present, during the opening and closing process of various valves, the spools are easily eroded by high-pressure media.
[0005] At present, there is no multi-functional automatic changing valve. Even if one or two of the functions can be realized, the actuator is required to complete the work. At the same time, the purchase cost and use cost are high, and it cannot be opened and closed quickly.

Abstract

The invention discloses a dual-structure core tube valve. The valve is one of conventional core tube valve plate blocks in the original core tube valve main series. A valve core tube is a fixed part and coaxially penetrates through a sleeve I of a valve body, a valve body inner cavity and a sleeve II of the valve body, an axial interlayer is arranged in the middle of the valve core tube, two axialadjacent sides of the interlayer are each provided with at least one radial circulation hole of an input segment and an output segment, a hollow-out inverted-L-shaped hole way is arranged on the halfsolid part of the valve body inner cavity, and a radial hole opening corresponds to and is matched with the radial circulation hole of the paired input segment, an annular valve element surrounding the interlayer and an annular valve base on the throat of the sleeve II form a seal pair, the difference of the outer diameters of the input segment and the output segment is larger than or equal to 0,the input segment and the sleeve I are in shaft hole type fit, the output segment and the sleeve II are in shaft hole type fit, and a seal is arranged on at least one combination part. A driving element and an elastic element for enabling the valve body to axially move in a reciprocating manner are arranged on the outer end of the valve body. The structure is simple, reliability is high, the valve adapts to high-pressure and strict conditions, medium erosion is prevented, and flexible characteristics are achieved.

Description

technical field [0001] The dual structure core tube valve of the present invention belongs to the field of valves, and is one of the conventional core tube valve plates in the core tube valve mother series invented by myself, involving opening and closing, adjustment, decompression, flow limiting, and check ; The dual structure is that the hollow channels of the valve body participate in the circulation. [0002] As an opening and closing valve, its structural advantage has the characteristic of avoiding erosion immediately before the sealing pair is closed. [0003] As a regulating, decompression, flow limiting, and check valve, its structural advantage has the characteristics of automatic flexibility. When the normal medium pressure is in the fully open state; when it is higher than the normal pressure, it will change from the normal flow state to the regulation state. ;It is in the state of automatic decompression and flow limitation when the pressurization continues; when...
