Description
Technical field
The utility model relates to the automatic controller of the oven fuel gas shutoff valve that moves under the unpowered Power Supplies Condition in a kind of oil-gas gathering and transportation field, more precisely, is a kind of little energy consumption valve shut-off means.
Background technique
At present, under unpowered Power Supplies Condition, a lot, still fail to adopt automatic control technology that the running state of oven is carried out continuous monitoring, also fail to use the technique device that guarantees when the oven abnormal running, can in time cut off combustion gas at the oven of usefulness.Part oven adopted with the compressed natural gas be the pneumatic diaphragm valve of power as safety cut-off, be about to the upper chamber that rock gas is introduced membrane valve, promote barrier film and cut off combustion gas.Since do not have that the well site of electricity in most cases uses be moisture oil well associated gas as combustion gas, can influence the use of control valve during winter operation as the moisture associated gas of power.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of under unpowered Power Supplies Condition, be fit to various oven, especially be fit to the oven that with oil well association moisture is combustion gas supporting, by adopting safety cut-off valve, can when the abnormal running state appears in oven, cut off combustion gas rapidly, guarantee little energy consumption valve shut-off means of safety in production.
The technical solution of the utility model is: comprise power supply, it is made of execution connecting rod 9, substrate 10, bearing pin 1, lever 5, electromagnet 6, position limit switch 11, control pin 7.Substrate 10 is fixed on the valve body top of cut-off valve 8, one end of substrate 10 is connected with connecting rod 2 by bearing pin 1, one end of lever 5 is connected with connecting rod 2 by bearing pin 3, the other end is provided with counterweight 13, lever 5 is connected with an end of carrying out connecting rod 9 by bearing pin 4, the armature of electromagnet 6 is connected with control pin 7, power input terminal 12 1 ends are connected with electromagnet 6, the other end is connected with position limit switch 11, the other end of position limit switch 11 is connected with electromagnet 6, and the other end of carrying out connecting rod 9 is connected with the valve rod of cut-off valve 8.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that: be fit to the automatic control of various oven cut-off valves, can when the abnormal running state appears in oven, cut off combustion gas rapidly, guarantee safety in production.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figures 1 and 2, one end of the utility model substrate 10 is connected with connecting rod 2 by bearing pin 1, and the other end is provided with position limit switch 11, and substrate 10 is fixed on the valve body top of cut-off valve 8, one end of lever 5 is connected with connecting rod 2 by bearing pin 3, and the other end is provided with counterweight 13.Also can replace counterweights 13 with spring 14, spring 14 is arranged on the other end of lever 5, spring 14 connects substrates 10.Lever 5 is connected with an end of carrying out connecting rod 9 by bearing pin 4, the armature of electromagnet 6 is connected with control pin 7, power input terminal 12 1 ends are connected with a tenminal block of electromagnet 6, the other end is connected with position limit switch 11, the other end of position limit switch 11 is connected with another tenminal block of electromagnet 6, and the other end of carrying out connecting rod 9 is connected with the valve rod of cut-off valve 8.
Working procedure embodiment of the present utility model: this little energy consumption valve shut-off means under the initialization state, power input terminal 12 no electrical signal, electromagnet 6 is not switched on, connected control pin 7 is for stretching out state, control this moment pin 7 supports lever 5.Lever 5 connects carries out connecting rod 9, handles cut-off valve 8 and is in opening state, and two contacts of position limit switch 11 are in electric conducting state.When oven generation abnormal running, its control gear can send an electrical signal, through power input terminal 12 inputs, because this moment, position limit switch 11 was an on state, stroke is set in one of electromagnet 6 energising traction armature pulling control pins 7 motion, makes lever 5 lose support, and lever 5 promotes to carry out connecting rod 9 and moves under the effect of counterweight 13 or spring 14, close cut-off valve 8 by valve rod, realized the safety cut-off function.Carry out connecting rod 9 and can under the effect of counterweight 13 or spring 14, produce an enough big vitality, make cut-off valve 8 be in off state all the time, cutting off the input power supply, thereby with moment small electric weight realized the shutoff of cut-off valve 8.If open cut-off valve 8 again, then need human intervention, make this valve shut-off means get back to original state.
For adapting to the operating conditions of unpowered power supply, electromagnet 6 adopts 24V and following DC electrical source to drive, and power supply can be storage battery, dryelement cell or sun-generated electric power, has realized the goal of the invention of little energy consumption valve shut-off means thus.
