Abstract

The utility model relates to a liquefied natural gas power-driven energy saving valve which comprises an air inlet pipe, an air outlet pipe, a knob, a casing, a gear, a switch, a valve body and valve rods. The utility model is characterized in that the air inlet and the air outlet of the valve body are respectively connected with the air inlet pipe and the air outlet pipe, and a manual and a power valve rods are arranged along the horizontal direction of the valve body. A motor controlled by a switch block is connected with the power valve rod through a gear set, a compression rod and a contact rod having a limited rod are arranged on the casing, and one end of the limited rod is connected with a limited plate. The utility model has the advantages of simple structure, easy use and good energy-saving effect.

Description

The electronic energy-conservation valve of liquid gas

Technical field

The utility model relates to the gas-fired boiler technical field, the electronic energy-conservation valve of particularly a kind of liquid gas.

Background technique

The centre lathe type liquefaction air valve that uses at present, mainly comprise suction tude, steam outlet pipe, knob, housing, O-ring seal, valve body and valve rod, structure is one tunnel input, two-way output, wherein have one the tunnel to be Chang Minghuo, its shortcoming is when round-bottomed frying pan leaves cooking stove, stove fire can not reduce or close automatically, causes the waste of combustion gas.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, can prevent the electronic energy-conservation valve of liquid gas of combustion gas waste.

The utility model is to realize like this, it comprises suction tude, steam outlet pipe, knob, housing, gear, switch, valve body and valve rod, the suction port that it is characterized in that valve body is connected with suction tude, steam outlet pipe respectively with the air outlet, substantially horizontal along valve body is provided with manually and electronic two valve rods, motor by switching group control is connected with electric stem by gear train, housing is provided with the feeler lever of depression bar and band position-limited lever, and an end of position-limited lever is connected with banking stop.

The utility model compared with prior art has simple in structure, the advantage of easy to use and good energy-conserving effect.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described;

Fig. 1 is the structural representation of the electronic energy-conservation valve of liquid gas;

Fig. 2 is that depression bar is arranged on the structural representation on the housing;

Fig. 3 is the circuit diagram of Fig. 1.

Embodiment

As Figure 1-3, the electronic energy-conservation valve of this liquid gas comprises suction tude 1, steam outlet pipe 2, knob 3--4, housing 5, gear 6-7, valve body 8, valve rod 9-10, motor 11, depression bar 12, position-limited lever 13, banking stop 14, feeler lever 15, spring 16, switch 17-19, the suction port of valve body 8 and air outlet respectively with suction tude 1, steam outlet pipe 2 is connected, substantially horizontal along valve body 8 is provided with manual opening stem 9 and electric stem 10, motor 11 by switching group 17-19 control passes through

gear train

6,7 are connected with electric stem 10, housing 5 is provided with the feeler lever 15 of depression bar 12 and band position-limited lever 13, one end of position-limited lever 13 is connected with banking stop 14, during use, depression bar 12 is installed in the end eaves of kitchen range mouth, the pressure that utilizes round-bottomed frying pan to put, make depression bar 12 produce displacement and drive 17 among the switching group 17-19 and move, this switch is being controlled the sense of rotation of motor 11, turn to reverse, and by

gear

6,7 slow down, obtain required moment, this moment is taken turns with automatically controlled knob 4 by gear 6 and is connected, making automatically controlled knob 4 tolerance of controlling is standard-sized sheet, this position is by position-limited lever 13, banking stop 14, feeler lever 15 is determined, press motor 11 backward stop switches 18, make it cut off motor 1 reverse power supply, the vigorous fire state when being the processing dish this moment; When round-bottomed frying pan is removed cooking stove, depression bar 12 is because the effect of spring 16 resets, and motor 11 is swung to, and switch 17 resets, at this moment motor 11 clockwise directions rotate, this positioning control throughput is less, is the low baking temperature state, and feeler lever 15 presses motor up time cutoff switch 19 simultaneously, motor is forward stopped operating, up to next operation, in operating process, knob 3 can carry out the fine setting and the switch of stove fire.

Claims

1, the electronic energy-conservation valve of a kind of liquid gas, it comprises suction tude, steam outlet pipe, knob, housing, gear, switch, valve body and valve rod, the suction port that it is characterized in that valve body is connected with suction tude, steam outlet pipe respectively with the air outlet, substantially horizontal along valve body is provided with manually and electronic two valve rods, motor by switching group control is connected with electric stem by gear train, housing is provided with the feeler lever of depression bar and band position-limited lever, and an end of position-limited lever is connected with banking stop.
