Abstract
The invention discloses a track transfer regulating valve. The track transfer regulating valve comprises a valve body, wherein a valve body medium flowing passage is formed in the valve body; a valve core is arranged on the valve body medium flowing passage, and consists of an inner valve core and an outer valve core; the outer valve core is arranged on the valve body medium flowing passage; a valve core medium flowing passage communicated with the valve body medium flowing passage is formed in the outer valve core; and the inner valve core is arranged on the valve core medium flowing passage. When the flow rate of the valve is required to be increased, the inner valve core in the outer valve core can be opened on the premise of opening the original outer valve core, so as to increase the flow rate of the valve body; and when the flow rate of the valve is required to be lower than that of the outer valve core, the outer valve core can be closed and the inner valve core in the outer valve core is opened to reduce the flow rate of a flowing medium, so that the precision of the flow rate can be controlled better; therefore, the track transfer regulating valve can regulate the flow rate to be larger than that of an original single valve core and regulate the flow rate to be smaller than that of the original single valve core, the flow rate regulating range of the regulating valve is effectively widened, and the application range of the regulating valve is wider.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of change rail modulating valve.
Background technique
Modulating valve is a kind of common type in the valve, and modulating valve generally includes valve body, is provided with valve body MEDIA FLOW circulation passage in the valve body; Said valve body MEDIA FLOW circulation passage is provided with the spool of control valve body MEDIA FLOW circulation passage flow; Though can come the flow of regulation valve body through the control spool,, control through single spool in the existing technology or the flow of regulation valve body owing to the influence that receives adjusting angle between the size of spool own and spool and the valve body MEDIA FLOW circulation passage etc.; Has certain narrow limitation; Usually can only regulate the flow in a certain particular range, surpass or the flow that is lower than this particular range all can't be regulated, therefore cause the Applicable scope of modulating valve little.
Summary of the invention
To the deficiency of existing technology, the invention provides the wider change rail modulating valve of a kind of flow adjustment range.
For realizing above-mentioned purpose, the invention provides a kind of change rail modulating valve, comprise valve body; Be provided with valve body MEDIA FLOW circulation passage in the described valve body, said valve body MEDIA FLOW circulation passage is provided with the spool of control valve body MEDIA FLOW circulation passage flow, and described spool is made up of inner spool and outer spool; Described outer spool is installed on the valve body MEDIA FLOW circulation passage, is provided with the spool MEDIA FLOW circulation passage that is connected with valve body MEDIA FLOW circulation passage in the outer spool, is equiped with inner spool on the described spool MEDIA FLOW circulation passage; Be connected with outer valve rod on the described outer spool; Be connected with inner valve stem on the described inner spool, and described inner valve stem is located in the outer valve rod, is provided with the gland nut of stuffing box packing and fixing seal filler between inner valve stem and the outer valve rod; Be set with Returnning spring on the described inner valve stem; Described Returnning spring is positioned at spool MEDIA FLOW circulation passage, and the upper end of Returnning spring and the conflict of spool MEDIA FLOW circulation passage inwall, and the lower end of Returnning spring and inner spool are conflicted.
The invention has the beneficial effects as follows: adopt said structure; Because described spool is to be made up of inner spool and outer spool; Outer spool is installed on the valve body MEDIA FLOW circulation passage, and inner spool is installed on the spool MEDIA FLOW circulation passage, therefore when valve needs augmented flow; Situation that can spool is opened outside original is opened the flow that inner spool in the outer spool enlarges valve body again; Outside valve need be lower than, during the flow of spool, can outer spool be closed, open the inner spool in the outer spool; Reduce the flow of circulation medium with this; Be convenient to better control flow rate precision, so compare the modulating valve of existing technology single spool, modulating valve provided by the present invention; Both can realize being higher than the adjusting of original single spool rate-of flow; Also can realize being lower than the adjusting of original single spool rate-of flow, enlarge the flow adjustment range of modulating valve effectively, make that also the Applicable scope of modulating valve is wider.
The present invention can further be set to also be connected with cartridge cover on the described outer spool; Be evenly distributed in several medium discharge orifices on the described cartridge cover, and the two ends of several medium discharge orifices are connected with valve body MEDIA FLOW circulation passage, spool MEDIA FLOW circulation passage respectively on the said cartridge cover.
Adopt said structure; Set up cartridge cover on the spool outside, can be through the shunting of several medium discharge orifices on the cartridge cover, the further flow of refinement spool MEDIA FLOW circulation passage; Feasible flow from the outflow of spool MEDIA FLOW circulation passage is more even, and the low discharge applicable scope also can be lower.
