Description

The fluid-mixing modulating valve

Technical field

The utility model relates to a kind of control set for adjusting, relates in particular to a kind of fluid-mixing modulating valve.

Background technique

It is comparatively common with valve to regulate control, its objective is two kinds of different fluid are mixed (as two kinds of different liquid are mixed, two kinds of different gases are mixed, even may be that liquid is mixed with gas), when two kinds of different fluid are mixed, under many circumstances, need the ratio of mixing is controlled, such as the temperature controlled valve core product that has now occurred, the spool inner core that is adopted in the temperature-sensitive moving valve core is a slide block in axial sliding, the size of regulating cold water outlet and hot water mouth by the slip of slide block in spool, regulate the different proportion that enters of cold water and hot water with this, realize adjusting the mixing water temperature.

The shortcoming of this structure is:

In this temperature-sensitive moving valve core, cold water is the total cold water outlet of flowing through, and hot water is the total hot water mouth that flows through, and water flow is wayward, the trace of slide block moves the rapid change that just might cause cold water outlet and hot water mouth's size, and the ratio that cold water and hot water enter can not accurately be adjusted.

This shows, for overcoming the defective of prior art, be badly in need of a kind of new mixing modulating valve of exploitation, so that the ratio of two kinds of different fluid in the regulating and controlling fluid-mixing accurately.

The objective of the invention is to overcome the deficiencies in the prior art, a kind of fluid-mixing modulating valve that can accurately regulate the meticulous adjusting control of ratio, realization of two kinds of different fluid is provided.

The utility model is achieved through the following technical solutions:

The fluid-mixing modulating valve, comprise the modulating valve overcoat, the modulating valve overcoat is provided with first flow channel, second flow channel and flow pass, flow pass is located between first flow channel and second flow channel, the modulating valve inner core is housed in the modulating valve overcoat, and being provided with the controlling device that axial displacement is regulated to the modulating valve inner core, the modulating valve inner core can move axially in the modulating valve overcoat; The modulating valve inner core is provided with at least two and regulates passage, and first flow channel communicates with flow pass by regulating passage, and second flow channel communicates with flow pass by regulating passage; It is passage first end and passage second end that each bar is regulated the passage two ends, lays respectively at first and flows into the channel side and the second flow channel side; Each bar is regulated the passage first end axial position difference of passage, and it is also different that each bar is regulated the passage second end axial position of passage.On described modulating valve outer casing inner wall, be equipped with elastic ring between first flow channel and the flow pass and between second flow channel and the flow pass.

Described modulating valve inner core can be made up of for second section first section of inner core and inner core, and described passage first end is located on first section of the inner core, and described passage second end is located on second section of the inner core.

Described modulating valve overcoat by first section in overcoat, second section in overcoat and be connected in first section in overcoat and second section in overcoat between the overcoat stage casing form, described first flow channel is arranged on first section in the described overcoat, and described flow pass, second flow channel are arranged on the described overcoat stage casing.

Described adjusting passage is at least two, each adjacent passage first end is in axial position difference (comprise elongated successively or shorten successively or multiple mode such as irregular alignment), and each adjacent passage second end changes (comprise elongated successively or shorten successively or multiple mode such as irregular alignment) successively at axial position.

Described adjusting passage also can be at least two groups, every group at least three, in every group, each adjacent passage first end is in axial position difference (comprise elongated successively or shorten successively or multiple mode such as irregular alignment), and each adjacent passage second end is in axial position difference (comprise elongated successively or shorten successively or multiple mode such as irregular alignment).

The controlling device that axial displacement is regulated to the modulating valve inner core contains inner core spring, support head and with support the adjusting screw rod that head thread cooperates, adjusting screw rod passes modulating valve overcoat one end, supports head and inner core spring the modulating valve inner core is pressed in the modulating valve overcoat.

Working principle of the present utility model is:

Because the modulating valve inner core can move axially in the modulating valve overcoat, and the modulating valve inner core is provided with at least two adjusting passages, and first flow channel communicates with flow pass by regulating passage, and second flow channel communicates with flow pass by regulating passage; Each bar is regulated the passage first end axial position difference of passage, and it is also different that each bar is regulated the passage second end axial position of passage.So the moving axially of modulating valve inner core make to be regulated passage and changed with the number of first flow channel and the second flow channel conducting respectively, and the flow of realizing the liquid that flows into by first flow channel and second flow channel changes, and realizes thus the mixed proportion of two kinds of different fluid is regulated.

The utility model has the following advantages with respect to original design:

The flow of fluid of first flow channel and second flow channel of flowing through is to change by the quantity of regulating the passage conducting to regulate, and the mixed proportion of two kinds of different fluid is regulated more accurate.

Regulate passage and be located at modulating valve inner core middle part, promptly regulate passage and communicate with first flow channel and second flow channel simultaneously, regulating passage for one can time processing be shaped, easy to process.

The modulating valve inner core also can be taked segmentation structure, promptly is divided into second section of first section of inner core and inner core, and this structure can make things convenient for the processing of inner core.

The adjusting channel design of many groups and passage first end and the axially variation successively of passage second end of regulating passage its objective is that the fluid that making flows through regulates passage evenly distributes, so that the mixed proportion of two kinds of different fluid is stable on the modulating valve inner core.

The controlling device that the axial displacement of modulating valve inner core is regulated is that the circumferential movement with adjusting screw rod is converted into the axial motion to head, compresses the modulating valve inner core and makes it that axial motion take place, so that the influx of two kinds of different fluid is regulated.

In brief, the utility model has the advantages that:

1, more accurate to the adjusting of the mixed proportion of two kinds of different fluid;

2, the adjusting passage on modulating valve inner core processing can single forming, and is easy to process;

3, the modulating valve core arrangement of segmented can make things convenient for the processing of inner core.
