Abstract
The utility model discloses the linkage structure of a kind of crosspointer solenoid valve and thermocouple, it is characterized in that: comprise a solenoid valve sheath and a thermocouple well; Described solenoid valve sheath one end is provided with flange, and the solenoid valve sheath the other end is provided with groove, and solenoid valve sheath is connected with solenoid valve; Described thermocouple well outer symmetrical is provided with claw, and described thermocouple well adopts elastic material to make, and thermocouple well is connected with thermocouple, solenoid valve sheath and thermocouple well clamping.The beneficial effects of the utility model are: structure is simple, after solenoid valve and the installation of TC, through transporting or using for a long time, can effectively prevent solenoid valve and thermocouple from getting loose.
Description
Technical field
The utility model relates to the linkage structure of a kind of crosspointer solenoid valve and thermocouple.
Background technique
gas electromagnetic valveit is the safe emergency shut-off means of gas pipeline.It can with gas leakage
alarm systemconnect or be connected with fire-fighting and other intelligent alarm control terminal modules etc., realizing on-the-spot or remote auto/manual emergency cut-out source of the gas, guarantee to use gas safety.When the sharp pounding meeting accident flame-out or harmful, valve can be closed automatically.Valve opening must through manual intervention, manually opened, meets safety control specification, meets accident treatment feature.
At present, known thermoelectric (al) type gas extinguishing fire protective gear is made up of thermocouple and solenoid valve.Thermocouple can produce the thermoelectrical potential of millivolt level in flame, is arranged on solenoid valve in blast tube and is connected with thermocouple, and the thermoelectrical potential accepting thermocouple keeps adhesive to make combustion gas be in opening state.If flame extinction, the thermoelectrical potential of thermocouple disappears, and solenoid valve departs from makes combustion gas be in closed condition, to guarantee safety.Crosspointer solenoid valve, compared with general solenoid valve, many contact pins, at ignition phase for external power access, to realize zero-second ignition.The thermoelectrical potential produced due to thermocouple is millivolt level, so the reliability that thermocouple is connected with solenoid valve is most important.
Structure before improvement as depicted in figs. 1 and 2, solenoid valve 100 is connected with support 1, sheath 4 is connected with thermocouple 200, large needle 2 in solenoid valve 100 and little pin 3 and the large needle socket 5 in thermocouple 200 and little needle socket 6 in mating connection, just rely on the mistake drive fit of the column contact pin of solenoid valve and the poroid socket of thermocouple to realize.This kind of connection cannot ensure that solenoid valve is connected with reliable after the installation of TC.A lot of market is complained, and it is normal for just having installed rear connection, but after being through transport and long-time use, solenoid valve and thermocouple have the phenomenon got loose, and cause gas utensil normally to use.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides the linkage structure of a kind of crosspointer solenoid valve and thermocouple.
The utility model adopts following technological scheme:
A linkage structure for crosspointer solenoid valve and thermocouple, is characterized in that: comprise a solenoid valve sheath and a thermocouple well;
Described solenoid valve sheath one end is provided with flange, and the solenoid valve sheath the other end is provided with groove, and solenoid valve sheath is connected with solenoid valve;
Described thermocouple well outer symmetrical is provided with claw, and described thermocouple well adopts elastic material to make, and thermocouple well is connected with thermocouple, solenoid valve sheath and thermocouple well clamping.
As preferred technological scheme, thermocouple well adopts nylon material.
Compared with prior art, the beneficial effect of the linkage structure of a kind of crosspointer solenoid valve of the utility model and thermocouple is: structure is simple, after solenoid valve and the installation of TC, through transporting or using for a long time, can effectively prevent solenoid valve and thermocouple from getting loose.
Accompanying drawing explanation
Fig. 1 is the structural representation of solenoid valve sheath before improving.
Fig. 2 is the structural representation of thermocouple well before improving.
Fig. 3 is the structural representation improving rear electromagnetic valve sheath.
Fig. 4 is the structural representation of thermocouple well after improving.
In above accompanying drawing: 100-solenoid valve; 200-thermocouple; 1-support; 2-large needle; The little pin of 3-; 4-sheath; The large needle socket of 5-; The little needle socket of 6-;
11-solenoid valve sheath; 12-flange; 13-groove; 14-thermocouple well; 15-claw.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described:
A linkage structure for crosspointer solenoid valve and thermocouple, support 1 passed through drive fit and was connected with solenoid valve body, it is characterized in that: comprise solenoid valve sheath 11 and a thermocouple well 14; Described solenoid valve sheath 11 one end is provided with flange 12, and solenoid valve sheath 11 the other end is provided with groove 13, and solenoid valve sheath 11 is connected with solenoid valve 100; Described thermocouple well 14 outer symmetrical is provided with claw 15, described thermocouple well 14 adopts elastic material to make, thermocouple well 14 adopts nylon material, thermocouple well 14 is connected with thermocouple 200, solenoid valve sheath 11 and thermocouple well 200 clamping, after solenoid valve 100 and thermocouple 200 are installed, solenoid valve 100 large needle 2 and little pin 3 insert in the large spring hole scoket of thermocouple 5 and little spring hole scoket 6 respectively, the upper end of thermocouple well 14 is inserted in solenoid valve sheath 11, and thermocouple well 14 claw 15 snaps in solenoid valve sheath 11 groove.
The linkage structure of a kind of crosspointer solenoid valve of the utility model and thermocouple, structure is simple, after solenoid valve and the installation of TC, through transporting or using for a long time, can effectively prevent solenoid valve and thermocouple from getting loose.
It should be noted that, these are only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
