Abstract
The utility model relates to a temperature controller for boilers, comprising protecting screw nuts, a regulating turn knob, an anti-loosing plug, an upper cavity body, a linkage rod, a valve body, a return spring and a telescopic joint. The utility model is arranged on the crude oil convey pipelines of the exteriors of a boiler body or a water jacket boiler. The regulating turn knob is arranged on the corresponding position, the telescopic joint automatically balances the gas volume of the interior of the gas inlet pipeline, and the function of controlling the temperature of the interior of the boiler body is performed. As the utility model has simple structure and small volume, performs the function of the boiler temperature automatically controlling the gas quantity, the utility model is widely used for the temperature control of boilers and heating boilers.
Description
The utility model belongs to device for monitoring temperature, particularly a kind of device for monitoring temperature that is used for pot.
Various heating boilers and oil field main line transporting water blind roaster, the heating of heating boiler since temperature can not control to use and bring certain difficulty, cause energy dissipation also to be easy to generate the fried accident of body of heater, temperature controller in the existing technology, because complex structure, the cost height is operated restive, be difficult for to promote, a kind ofly can control fuel gas supply by mechanical interlock according to the temperature of testee; Thereby the furnace body temperature controller of realizing the solar term purpose can overcome the deficiency of existing technology, this task that the utility model proposed just.
The utility model is achieved in that
The outer output oil pipeline of pipe nipple above the utility model 22 by flange and water jacket furnace joined.
At first regulate the adjusting knob (23) at top during use, the tolerance increasing that promotes piston (6) and trace (10) downwards, reaches spool (13), at this moment crosses gas port 12, water jacket furnace furnace wall and heated crude oil temperature raise, when the crude oil temperature of output reaches the certain numerical value temperature value, stop adjusting knob (2), when inlet end air pressure reaches 2.5MPa, telescopic joint (18) expansion is extended and is interacted with back-moving spring (14), just, the tolerance that gas port (12) was passed through makes oily temperature meet the requirements of temperature value, and this point is called equilibrium point or initial value; When furnace wall temperature or outside the output oil temperature telescopic joint (18) that raises when exceeding uniform temperature expand and upwards promote transmission rod, spool 13 just stoped gas port tolerance to flow into, when outer output oil temperature is lower than setting value, press in the telescopic joint 18 and diminish, shrink, spool (13) moves down, and the tolerance in the gas pipeline increases, thereby realizes control combustion gas target automatically.
Advantage of the present utility model is, when the testee temperature changes, thereby telescopic joint can expand or shrink the valve position that makes linkage and increase or diminish, what of the interior air demand of gas pipeline realization control automatically, this apparatus structure is simple, and volume is little, is easy to safeguard, can play boiler temperature and control gas quantity automatically, use to reach the purpose of saving the energy.
The utility model is provided by following examples:
Illustrated below in conjunction with accompanying drawing:
Accompanying drawing: boiler temperature controller architecture synoptic diagram
The utility model is by protection nut (1); adjusting knob (2); locking stifled (3); connector (4); epicoele cap (5); piston (6); upper cavity (7); piston spring (8); epicoele seat (9); trace (10); valve body (11); cross gas port (12); spool (13); back-moving spring (14); shelves seats (15); cavity of resorption head (16); transmission rod (17); telescopic joint (18); lower chamber (19); cavity of resorption dish (20); bulb (21); pipe nipple (22); sealing gasket (23); joint (25); fabrication hole (26) is formed.
The utility model be in the inlet end of valve body (1) and outlet side by screwed connection on gas supply line (24); in valve body (1) the inside a spool (13) is arranged; two apertures symmetrical with inlet end axis normal direction are arranged on valve body top; respectively have in the hole between the trace (10) of two same diameter length and the aperture and be clearance fit; epicoele seat (9) is a joint that has interior male thread; and upper cavity (7) and valve body (11) are linked together with screw thread; the upper cavity inherence is placed with piston spring (8) near epicoele seat (9) top; a piston with the level (6) is arranged above the spring; the piston bottom contacts with trace (10); piston top contacts with adjusting knob (2); epicoele cap (5) is a joint that has interior male thread; be connected with upper cavity (7) by male thread; interior button is connected together with connector (4); link together by interior screw thread and adjusting knob (2) in the connector (4); locking stifled (3) of band screw thread are equipped with on connector top; compress sealing gasket (23) and buckle with connector (4) top male thread with tin hat (1) interior and be combined together, tin hat can play the effect of protection adjusting knob (2).
In the lower seat of valve body (11) inner spool (13) back-moving spring (14) and shelves seats (15), cavity of resorption head (16) being arranged is a reducer union that is had male thread by two ends, its major part connection valve body (11), microcephaly connect lower chamber (19), the centre has a hole to penetrate among the transmission rod (17), spool (13) can be at lower chamber (19), interior telescopic joint (18), upper and lower effect promotes to produce displacement down, can realize controlling automatically the size of air inflow.
Telescopic joint (18) is bonded in above the cavity of resorption dish (20), the male thread of cavity of resorption dish (20) and lower chamber (19) are connected and are welding the expansion texture that bulb (21) forms temperature controller above the cavity of resorption dish, can insert gas filling technology hole (26) respectively according to the purposes difference in the cavity of resorption dish (20) in the temperature control expansion texture and also can insert bulb (21), (not drawing among the figure).
The material of the fabrication hole in the utility model (26), bulb (21) is that copper tube is manufactured and formed.When the utility model uses, bulb (21) can be connected controller by pipe nipple (22) on the external transport pipeline of water jacket furnace and measure, can obtain effect same.
