Abstract

The utility model relates to a multipurpose nozzle for a gas burner, comprising a front body with a nozzle and a back body assembled on the front body, wherein a hollow needle valve for cutting body on the end part of the front body is connected with a regulating valve rod of a cavity together; the needle valve can do reciprocating movement along the valve rod. The structure is simple; the operation is easy; the adjustment can be carried out at any time according to different gases and the change of different heat value and pressure of the same gas.

Description

Gas burner is used nozzle more

The utility model relates to the air feed nozzle that a kind of gas burner is used, and particularly a kind of step-less adjustment that can extensively be suitable for various combustion gas is used nozzle more.

At present, the air feed nozzle used of commercially available gas burner is the fixedly nozzle of spray orifice that has that gas only uses.After changing combustion gas, nozzle diameter is not changed, and burner then can't use.Same in addition nozzle had both made the combustion gas kind constant, and when the calorific value of this combustion gas or pressure changed, this nozzle spray orifice still can't be regulated, burner also therefore over-emitting black exhaust maybe can't light, combustion efficiency is bad, brings many inconvenience to the user.

The purpose of this utility model provides a kind of improved gas burner and uses nozzle more, and its simple in structure, easy operation is applied widely, can regulate according to the different calorific values of different combustion gas and same combustion gas and the variation of pressure at any time.

The purpose of this utility model is achieved in that this device comprises the precursor that has spray orifice and assembles back body on it, and the hollow section body acupuncture valve and the cavity regulating valve stem that wherein are contained in precursor spray orifice end link together, and this needle-valve axially moves back and forth along valve rod.

Because the utility model adopts the nozzle of modular construction, utilize the keying of hollow section body acupuncture valve control precursor spray orifice, so by metering pin valve along axially the moving back and forth of valve rod, be easy to realize the flow of stepless control combustion gas at spray orifice.It is simple in structure, operation easily, at any time according to the burning condition of different combustion gas and same combustion gas under the situation that different calorific values and pressure change, utilize the cavity regulating valve stem to come gap between metering pin valve and spray orifice end, satisfy the best combustion condition of combustion gas, improve fuel gas buring efficient, burner is over-emitting black exhaust, not tempering not, bring many convenience to the user, eliminate pollution environment.Therefore, the utility model applied range, highly versatile is convenient to promote.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic diagram of the utility model.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is that precursor has the structural representation that side joint is chewed.

Fig. 4 is that the valve rod end connects the structural representation of chewing.

Describe concrete structure of the present utility model in detail according to Fig. 1-4.This nozzle comprises the precursor 4 that has spray orifice 1, utilizes bolt to assemble back body 7 on it, hollow section body acupuncture valve 2, and cavity regulating valve stem 3 connects and chews 8 parts such as grade.Wherein connect and chew 8 sidewalls (as Fig. 3) that can be connected on precursor 4, also can be connected on the body 7 of back (as Fig. 1), also can not establish to connect and chew, directly the electronic ignition assembly is assembled in the end (as Fig. 4) of valve rod 3.The honorable through hole that cuts that is contained in hollow section body acupuncture valve 2 of precursor 4 spray orifice ends communicates with precursor 4 inner chambers.Needle-valve 2 both can directly link into an integrated entity (as Fig. 1) with valve rod 3, also can be by be threaded (as Fig. 3,4).Utilize adjuster 5 can make this needle-valve 2 axially move back and forth the distance that metering pin valve 2 front ends and spray orifice are 1 along valve rod 3.For prevent that needle-valve 2 from rotating when moving back and forth, on needle-valve 2 periphery walls axial channel 10 is arranged, circumferential gag lever post 9 is set on precursor 4 sidewalls, gag lever post 9 is inserted in the guide groove 10, and it can be vertically moved along guide groove.For avoiding combustible gas to leak, can adopt sealing gasket 6 sealings (as shown in Figure 1), also available flexible member 11 compresses taper valve rod 3 and directly encapsulates as spring, butterfly spring etc.

During use, should many be installed on the gas furnace with nozzle, and according to the requirement of fuel gas buring condition, suitably adjust adjuster 5, and drive valve rod 3 and make the distance of 1 of needle-valve 2 front ends and spray orifice be adjusted to the combustion gas optimal combustion state on request, operation is very easy.

Claims

1, a kind of gas burner is used nozzle more, comprises the precursor that has spray orifice and assembles back body on it, and the hollow section body acupuncture valve and the cavity regulating valve stem that it is characterized in that being contained in precursor spray orifice end link together, and this needle-valve axially moves back and forth along valve rod.

2, nozzle according to claim 1 is characterized in that on the needle-valve periphery wall axial channel being arranged, and the circumferential gag lever post on the preceding body sidewall inserts in the guide groove.
