Abstract
An automatic control regulating valve is mainly applied on a heat medium heater to automatically adjust the temperature of fuel or gas. A temperature sensor and a rigid capillary tube are connected through a bolt and are connected with a drive rod. A spring on the upper portion is connected with a switch chamber of a valve body through an opened regulating chamber to form a whole pneumatic automatic control regulating valve. Two seal rings are arranged in a pneumatic piston chamber, a seal box is arranged on the switch chamber of the valve body, and the seal ring in the box can be changed. The regulating chamber is opened, and can conveniently set the pressure values of opening temperature and closing temperature. The utility model has the beneficial effect that the automatic control regulating valve can conveniently set cling-opening pressure value, and has excellent sealing performance and safer and more reliable use.
Description
One, technical field
The utility model relates to a kind of from control regulation valve, is specially adapted to oil field gathering and transportation pipeline heating agent stove and regulates fuel oil or fuel gas temperature automatically.
Two, background technique
At present, in the flow circuit heating process of oil field, because amount of infusion fuel tolerance instability causes oil stream heating-up temperature to be difficult to control.The nonmetal pipe network in oil field is caused serious harm.Based on the modulating valve that is applied to regulate automatically on the steam boiler fuel oil or fuel gas temperature now, structure more complicated; Regulate difficulty, need open conditioning chamber and regulate; And sealing effect is relatively poor.Cause many inconvenience to use.
Three, summary of the invention
Goal of the invention
In order to overcome the problems referred to above, the utility model provides a kind of temp autocontrolled modulating valve, and this temp autocontrolled modulating valve is simple in structure, and three chambers, upper, middle and lower are arranged, the conditioning chamber, the valve body switch gear room that be respectively the pneumaticpiston chamber, open.Can regulate easily and adjust, and excellent sealing performance is arranged.
Technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: temperature sensor is connected by bolt with the rigidity capillary tube and drive link connects together.The pneumaticpiston chamber on top, temperature conditioning chamber links to each other with the switch gear room of valve body by open conditioning chamber, forms whole air pressure adjustment internally piloted valve.At the indoor two seals circle that is provided with of pneumaticpiston, in the switch gear room of valve body, be provided with sealing case, the seal ring in the box can be changed.Conditioning chamber is open, easily the setting switch force value.
The spring deformation power of temperature conditioning chamber and the swell increment of bellows are adjusted at the numerical point of regulation by regulating, and when air pressure was lower than the numerical point of regulation, valve opening was in full-gear; Air pressure reaches the numerical point of regulation and when rising gradually, spring is compressed, and gas promotes valve rod and moves close valve orifice gradually.Pass the valve rod of manual adjustment chamber, be provided with and adjust screw and adjust cap, both strokes of can regulate raft bar, also can adjust valve rod travel in conjunction with the swell increment of the required maximum temperature pressure of close valve orifice and spring deformation amount and bellows, make it when arriving the maximum temperature force value of regulation, fully close valve orifice.
Beneficial effect
The beneficial effects of the utility model are, it is more safe and reliable to regulate temperature, pressure value, good seal performance, use easily.

Five, embodiment
In Fig. 1, temp-sensitive apparatus (1), rigidity capillary tube (2) are by being threaded and drive link (7) welds together, and pressure chamber (3), conditioning chamber (12), valve body switch gear room (18) are connected as a single entity by screw thread; The piston (4) and the spring (6) that have two seals circle (5) penetrate in the pressure chamber (3) together.Bellows (9), the conditioning chamber of opening (12) interior middle be provided with adjusting screw rod (11), adjusting nut (13) upward link to each other with piston (4), link to each other with switch valve rod (14) down, are used to regulate the setting switch force value.Switch valve rod (14) penetrates in the valve body switch gear room (18), and the joint has seal ring packing (17), and has packing briquetting (16), packing pressure cap (15) to prevent to reveal.
One spacing lateral pin (10) is arranged, to guarantee certain gas storage space in the air pressure adjustment chamber in the middle of the piston rod.
During work, temperature sensor (1) is put into the oil that needs heating, be used for measuring at any time the oil temperature, temperature sensor (1) expanded by heating (or meeting cold contraction), by rigidity capillary tube (2) swell increment (or contour projector) is passed to bellows (9) chamber, the shortening (elongation) of bellows (9) promotes valve rod (14) braking valve of band spring (6), thereby regulates fluid flow, regulates the temperature of controlling object.In the temperature regulation process, temp-sensitive apparatus (1) is passed to swell increment valve rod (11) continuously, and valve rod (11) comes fluid flow accurately to control by constantly adjusting the position, guarantees that system keeps stationary temperature in an operating range than broad.This valve can also be set by temperature and adjust and setting temperature.
Claims (2)
1. one kind from control regulation valve, and it is characterized in that: temp-sensitive apparatus, rigidity capillary tube weld together by screw thread and drive link, and pressure chamber, open conditioning chamber, bellows chamber, valve body switch gear room are connected as a single entity by screw thread.
2. according to claim 1 from control regulation valve, it is characterized in that: switch valve rod penetrates in the valve body switch gear room, and the joint has sealed packing.
