Abstract
The utility model relates to an evaporation vaporization pipe adjusting controller for a diesel vaporization stove, comprising a nozzle, an evaporation vaporization pipe, a valve rod, a valve needle, a spring, a sealing ring and a rear end cover. The utility model is characterized in that the conical body of the valve rod is arranged between the valve rod and the valve needle comprising a reinforcing needle body, a filtering conical needle body, a basic needle body and an adjusting needle tip body. The utility model has the advantages of long service life, high reliability, convenient operation and little carbon deposit, and the needle is uneasy to be broken off or twisted off.
Description
The utility model is a kind of diesel oil evaporation stove carburation by evaporation pipe control set for adjusting, is applicable in family expenses or the gasification burner that uses light diesel fuel or kerosene for the passengers.
The gasification burner of home-use or for the passengers combustion diesel fuel or kerosene in the prior art, as Chinese patent disclosed " a kind of vaporization oil stove that uses light diesel fuel or the kerosene " (patent No.: 85201699), its carburation by evaporation pipe control set for adjusting is mainly by the carburation by evaporation pipe, nozzle, composition such as valve rod and needle and spring, shown in the partial schematic diagram (Fig. 4) of this device, needle is an elongated needle of taper shape, be located in the sphere end face of valve rod in the heart, because needle is born the effect of regulating vaporization combustion and oil circuit switch simultaneously, and needle hot soak condition, if needle misalignment nozzle spray orifice or when regulating owing to thermal bending deformation fails to aim at the nozzle spray orifice, make the needle tip be subjected to compressing of the nozzle endoporus conical surface and fracture, particularly when closing oil circuit, be tightened in the nozzle spray orifice owing to needle, usually making needle be twisted into two parts or wear and tear at its needle root that is connected with valve rod sphere end face fractures, therefore usually cause gasification burner to use and interrupt, need to continue to use behind dismounting maintain and replace valve rod and the needle parts.For fear of the phenomenon that needle is twisted into two parts often occurring, the present operation instructions requirement carburation by evaporation pipe control set for adjusting when closing stove of this product can not be closed fully, just after turning distributive value down to the pressure oil tank pressure release of this stove, make nozzle no longer oil spout and burn-out, but this method makes a small amount of remaining oil carbonization at high temperature in burning red carburation by evaporation pipe and causes that carbon distribution increases, the plug nozzle spray orifice, and the carbon distribution of the frequent nozzle clearing of need, and before lighting next time, must inflate pressurization, so be not easy to use to the pressure oil tank of this stove.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of can prevent that needle from fractureing or twisted into two parts, reliable operation, easy to use, and can reduce carbon distribution, the diesel oil evaporation stove carburation by evaporation pipe control set for adjusting of long service life.
The intensity and the rigidity of needle can be concentrated and improve to the utility model by the fatigue stress that needle and valve rod is adopted transitional structure form progressively reduce needle and valve rod junction, and bear the oil circuit on-off action by valve rod, and needle is only born the effect of regulating vaporization combustion, thereby reaches the realization the purpose of this utility model.As shown in Figure 1, include nozzle (1), carburation by evaporation pipe (2), valve rod (3), needle (5), spring (6), the diesel oil evaporation stove carburation by evaporation pipe control set for adjusting that sealing ring (7) and rear end cap (8) etc. are formed, it is characterized in that: the valve rod of this device of a. (3) is provided with valve rod cone (4), valve rod cone (4) is located between needle (5) and the valve rod (3), make valve rod carry out the transition to needle by the valve rod cone convergent, having reduced the fatigue stress of junction concentrates, and valve rod cone also plays valve plug, in order to the open and close of control oil circuit; B. the needle of this device (5) as shown in Figure 2, by strengthening needle body (5a), transition circle awl body (5b), basic needle body (5c) and adjusting needle point body (5d) constitute, regulating needle point body (5d) remains in the spray orifice of nozzle (1), the diameter of the non-control and regulation section of the needle of this structure is bigger, intensity and rigidity are higher and thermal bending deformation is little, frangibility or root are not twisted into two parts, fail to aim at the phenomenon that spray orifice fractures when having avoided in the spray orifice that the needle point body remains in nozzle advancing and regulate owing to needle, and regulate the only size in the gap by its taper seat and the spray orifice size of regulating fuel delivery of needle point body, do not bear the effect of closing oil circuit, thereby avoided needle to be clamped and the phenomenon of twisting into two parts or fracture that causes by spray orifice; C. the diameter of bore of the nozzle of this device (1) is greater than the diameter of strengthening needle body (5a), less than the diameter of valve rod (3), when the oil circuit buttoned-up status, the taper seat of the input end of the endoporus of nozzle (1) and valve rod cone (4) joins identical (as shown in Figure 3).
After further reducing the spray orifice of carbon distribution plug nozzle and preventing the needle thermal bending deformation, hit folding and bending, the utility model can make adjusting needle point body (5d) in the said spray orifice that remains in nozzle (1) when oil circuit aperture maximum rating, and needle tip keeps the outer 0.5mm of the spray orifice output of outstanding nozzle (1).
The utility model is described in further detail to utilize accompanying drawing:
Fig. 1 is the installation diagram of a kind of diesel oil evaporation stove carburation by evaporation pipe control set for adjusting of the present utility model;
Fig. 2 is the partial structurtes figure of valve rod of the present utility model and needle parts;
Fig. 3 is the partial schematic diagram of the utility model when the oil circuit buttoned-up status;
Fig. 4 is the partial schematic diagram of the carburation by evaporation pipe control set for adjusting of a kind of vaporization oil stove that uses light diesel fuel or kerosene of the prior art.
Among Fig. 1: (1) is nozzle, and its diameter of bore is that φ 2mm, injection diameter are φ 0.52mm; (2) be the carburation by evaporation pipe; (3) be valve rod, be with spring (6) on it, between valve rod (3) and needle (5), be provided with valve rod cone (4); (7) be sealing ring, (8) are rear end cap.
The structure that has reflected valve rod and needle parts among Fig. 2, valve rod (3) diameter is φ 3.5mm, the long 2.5mm of valve rod cone (4), taper seat fineness
