Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further.
As shown in Figure 1, a kind of single-seat adjusting valve with manual driving device of the present embodiment, comprise: support 1, valve body 2, valve rod 31, guide pad 32, spool 33, left import and export 4, right import and export 5, bolt 7, through hole 11, protective film 12, fixed block 13 and positioning block 16, also comprise: metal washer 34, operating stem 61, fixing rod 62, manual adjustment wheel 63, temperature transducer 8, cooling unit 9, sealing gasket 10, packing layer 14, Packing seat 15 and pulley 17; Its support 1 abuts against above valve body 2, fixed block 13 abuts against above support 1, and it is inner that valve rod 31 enters support 1 by fixed block 13, fixing rod 62, and valve rod 31 is provided with guide pad 32, be connected with spool 33 bottom guide pad 32, metal washer 34 is located in the middle of guide pad 32 and spool 33; It is inner that its operating stem 61 is located at fixing rod 62, and operating stem 61 one end connects manual adjustment wheel 63, and the other end connects valve rod 31; Its temperature transducer 8 is located on support 1 inwall, and cooling unit 9 is located at positioning block 16 upper surface; Its positioning block 6 is embedded between support 1 and valve body 2, and sealing gasket 10 is located at positioning block 16 lower surface, and packing layer 14 is close to support 1 and positioning block 16 side, and Packing seat 15 is located at fixed block 13 and valve rod 31 joint; Its pulley 17 is located at valve body 2 bottom.
Further preferably as shown in Figure 1, its cooling unit 9 self is with alarm, and protective film 12 is close to valve body 2 bottom surface, and support 1 is fixed together by two, left and right sides bolt 7 and valve body 2; Its valve body 2 inner flow passage is S type, and left import and export 4, right import and export 5 all can be used as entrance or the outlet of fluid; Its packing layer 14, Packing seat 15 obtain by graphite material, and the inside and outside wall of through hole 11 and valve body 2 obtains by quieter material.
Modulating valve overall work principle of the present invention is: first medium fluid enters valve body 2 by left import and export 4, and its valve rod 31, through fixed block 13 and fixing rod 62, drives guide pad 32 to move up and down together with spool 33; When not needing rate-of flow by through hole 11, spool 33 is embedded in through hole 11 completely, and now metal washer 34 is close on valve body 2 inwall; When needs rate-of flow by time, spool 33 starts to move up and down according to the parameter preset, until metal washer 34 is close to sealing gasket 10 lower surface, now reaches peak rate of flow; Then, after rate-of flow reaches control overflow, valve rod 31 is together with guide pad 32, spool 33 transfixion, and rate-of flow is discharged from right import and export 5 through through hole 11; During work, valve rod 31, guide pad 32 and spool 33 are moving up and down in process, owing to there being the buffering of metal washer 34, packing layer 14 and Packing seat 15, therefore greatly reduce the wearing and tearing of modulating valve internal components; In addition when the critical temperature that modulating valve inside temperature normally works higher than it, first monitored by temperature transducer 8, and then cooling unit 9 starts emergent refrigeration, and triggers its internal alarm 9 simultaneously.
The working principle of modulating valve manual drives of the present invention is: when the main driving mode of modulating valve break down or regulate there is deviation time, manual drives mode can be adopted to regulate, first manually regulating wheel 63 makes operating stem 61 rotate, thus band ovable valve stem 31 upwards or move down, and carrys out moving up and down of regulating valve stem 31 according to the parameter preset.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
