Execution architecture 2 comprises No. two cylinders 20 be communicated with a cylinder 11, promote valve regulation structure 21, modulating valve 22, function medium passage 23, promote valve regulation structure 21 and comprise the control lever 211 being positioned at No. two cylinder 20 tops, the adjusting handle 212 coordinated with control lever 211 threaded upper ends, be sleeved on the Returnning spring 213 of control lever 211 lower end, first fixed plate 214 of fixed reset spring 213 upper end, the lacing wire 216 fixed by set screw nut 219 with the first fixed plate 214 two ends, the continuous motion stem 217 fixed by set screw nut 219 with lacing wire 216 bottom, be located at the coarse adjustment device 218 of continuous motion stem 217 lower end.Rotate the length of the adjustable continuous motion stem 217 of coarse adjustment device 218, when needs regulate valve position on a large scale, rotate coarse adjustment device 218 and continuous motion stem 217 is elongated or shortened.Be provided with in No. two cylinders 20 between second piston 201, second piston 201 and No. two cylinder bodies and be provided with seal ring 202, continuous motion stem 217 is connected with modulating valve 22 through the upper end-hole of No. two cylinders 20 and the second piston 201, lower end.Composition graphs 4, the upper end of Returnning spring 213 is fixed on the first fixed plate 214 by spring fixed clip 210, the lower end of Returnning spring 213 is fixed on the second fixed plate 215 by spring fixed clip 210, an opening is provided with in the middle part of first fixed plate 214, control lever 211 is fixed on the second fixed plate 215 through opening, lower end, makes control lever 211 become structure beyond independent of lacing wire 216.The rectangular shape of lacing wire 216 in upper opening, material can be reinforcing bar, and its top is fixed by set screw nut 219 and the first fixed plate 214 and encapsulated.Control lever 211 is provided with graduation indication, makes when rotating adjusting handle 212, and control lever 211 is up and drive the up stroke of continuous motion stem 217 to have certain restriction.The bottom of No. two cylinders 20 is connected by flange 24 with function medium passage 23, and continuous motion stem 217, through the seal ring in the middle part of flange 24, makes the fixing more firm of continuous motion stem 217.The modulating valve 22 being fixed on continuous motion stem 217 bottom is positioned at the middle part of function medium passage 23, and its side is channel entrance, and opposite side is channel outlet, and therefore modulating valve 22 plays the effect of controlling functions rate-of flow.
Be filled with hydraulic medium in pipeline 3 on the first piston 111 of a cylinder 11, on the second piston 201 of No. two cylinders 20 and between the two, hydraulic medium comprises hydraulic oil, water.No matter described unpowered temperature and pressure regulator valve are that feeler mechanism or actuator both can vertically install also can laterally (slightly tilt) to install, determine according to the kind of modulating valve 22, the kind (tank or pipeline etc.) of detected system and place demand, not harsh to site requirements, be applicable to medium-sized and small enterprises and use.If when modulating valve 22 is any one in gate valve, stop valve, needle value, then actuator 2 is vertical installation; If when modulating valve 22 is any one in butterfly valve, ball valve, stopcock, then actuator 2 laterally installs; If feeler mechanism 1 is vertical installation, then hydraulic medium adds the top that entrance 14 is positioned at a cylinder 11; If feeler mechanism 1 is for tilting to install, then hydraulic medium adds the side that entrance 14 is positioned at cylinder 11 top.If modulating valve 22 is descending closed valve, then function medium passage is heating medium passage, refers to Fig. 2; If modulating valve is up opening type valve, then function medium passage is coolant guiding channel, refers to Fig. 3.The operating method of described unpowered temperature and pressure regulator valve is manually-operable, and rotate adjusting handle 212 and make control lever 211 descending, pull continuous motion stem 217 descending by Returnning spring 213, namely valve closes (being closedown to rotation gate); Rotating adjusting handle 212 makes control lever 211 up, and pull continuous motion stem 217 up by Returnning spring 213, namely valve is opened (be rotation gate and outward winding).
The utility model both can be used as temperature control valve (TCV) and also can be used as pressure regulator valve, when as temperature control valve (TCV), in evaporant room 10, specific easily evaporative medium is added according to different temperatures control range, evaporative medium comprises organic substance, organic solution, inorganic matter, mineral solution, inorganic matter and organic mixed solution, when measured medium temperature raises, evaporative medium temperature is also along with rising, and then vapor tension raises, promote first piston 111 to rise in a cylinder 11, hydraulic medium is pressed in No. two cylinders 20, promote the second piston 201 to decline in No. two cylinders 20, promote valving mechanisms 21 descending, heat medium is made (to comprise steam, hot water, heat conduction wet goods) flow reduction, by reducing the flow of heat medium and then reducing the temperature of measured medium, when measured medium temperature declines, promote Returnning spring 213 in valve regulation structure 21 and pull continuous motion stem 217 up, heating medium flow is increased, thus measured medium temperature is raised.Therefore, when needs improve measured medium temperature, rotating adjusting handle 212 makes control lever 211 up, if adjustment stroke is excessive need first regulate coarse adjustment device 218, continuous motion stem 217 is extended, exerts pressure to Returnning spring 213, offset the pressure of a part of hydraulic medium, continuous motion stem 217 is up, the increased flow capacity of heat medium, and measured medium temperature raises; The then opposite spin adjusting handle 212 when needs reduce measured medium temperature.In like manner, when as pressure regulator valve, the lower end of evaporant room 10 is open, and the pressure that detected system provides substitutes the pressure that evaporative medium produces, and working principle is identical with temperature control valve (TCV) system.Same, when detected medium needs cooling, change modulating valve 22 into descending opening type valve by descending closed valve, heat medium is changed to cooling medium, just can realize the demand that chilling temperature controls.
In a preferred embodiment, using methyl alcohol as evaporative medium, the internal diameter 5cm of a cylinder 11, the internal diameter 10cm of No. two cylinders 20 is example, saturation vapour pressure 1.22kg/cm during temperature 70 C
2, saturation vapour pressure 1.47kg/cm during temperature 75 DEG C
2, increase pressure at a cylinder 11: 2.5 × 2.5 × 3.14 × (1.47-1.22)=4.9kg.According to pressure transfer principle, at No. two cylinders 20, pressure can occur increases by 4.9 ÷ 52 × 102=16.9kg, and this power is enough to the resistance promoting valve event and overcome seal ring.
The utility model utilizes evaporative medium to produce temperature or pressure change carrys out regulating and controlling valve, by the evaporative medium in evaporant room 10, temperature signal is converted to pressure signal, to be amplified in pressure conduction to two cylinder 20 of a cylinder 11 by hydraulic medium again, when as unpowered pressure regulator valve, to be amplified in pressure conduction to two cylinder 20 of a cylinder 11 by hydraulic medium by the pressure signal of measured medium, need not extra power be consumed, energy-conservation; The additional investment of air compressing and drying system is not needed compared with pneumatic control valve; Simple with electric control valve structure compared, cost is low, and maintenance expenses is low; User is required low, be particularly suitable for medium-sized and small enterprises and use.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
