Abstract
The utility model discloses a valve of a gas pipeline. The valve of the gas pipeline comprises a main valve body. A square valve core rod (3) which stretches upwards is arranged on the main valve body. The square valve core rod (3) of the main valve body is connected with a poking device (11) and a drive device in sequence. The poking device (11) is provided with an incomplete gear (12) with a notch (15). A screwing handle (13) is fixedly connected on the incomplete gear (12) and a square through hole (14) is arranged in the screwing handle (13) of the incomplete gear. The incomplete gear (12) penetrates through the lower end of the square through hole. The drive device is a motor (21) provided with a drive gear (22). A shielding outer casing (23) is arranged outside a connecting box of the motor (21). The drive gear (22) is meshed with the incomplete gear (12). The motor (21) is communicated with an automatic control system through a circuit.
Description
Technical field
The utility model relates to a kind of control valve unit, specifically relates to a kind of valve of gas pipeline.
Background technique
At present, a lot of families all are equipped with gas pipeline, owing to only be provided with a kind of control valve unit of manually operated type on these gas pipelines, exist so very large potential safety hazard; In actual life, often there is the people can be because of inadvertent when going out, forget to turn off just in use gas stove switch, cause utensil on the gas cooker by for a long time dry combustion method, be easy to like this initiation fire accident.
Summary of the invention
The utility model provides a kind of valve of gas pipeline for above-mentioned deficiency, and this valve of gas pipeline can make the use of gas pipeline safer.
The utility model is achieved in that a kind of valve of gas pipeline, and valve of gas pipeline mainly is comprised of valve body, striking gear and drive unit, and described valve body has the square valve core bar that protrudes upward; Described striking gear has one and is with partial gear jaggy, is connected with stubborn hand above the partial gear, and at partial gear and the stubborn square through hole that is provided with on hand up/down perforation, this square through hole and above-mentioned square valve core bar are complementary; Described drive unit is one, and this actuation gear is meshed with above-mentioned partial gear with the motor of actuation gear, and the outer installment of the terminal box of motor has screening can; This motor is connected with automatic control system by circuit; Partial gear is connected to by square through hole on the square valve core bar of valve body, and motor is connected with a joggle by actuation gear and this partial gear.
In sum, be connected with partial gear at the square valve core bar of valve body, this partial gear is meshed with the actuation gear of motor, and motor is connected with automatic control system by circuit; Go out when having forgotten to close gas stove switch as the user like this, at this moment can be with mobile phone to this automatic control system transmitted signal, automatic control system receives behind the signal thereupon starting electrical machinery with the valve closing of this family's gas pipeline control valve unit; Moreover, in case gas leakage or fire accident occur, this valve also can automatically be closed.Use unsafe problem from truly having solved existing family gas pipeline.
Description of drawings
Fig. 1 is the exploded view of a kind of valve of gas pipeline of the utility model;
Fig. 2 is the structural representation after a kind of valve of gas pipeline shown in Figure 1 makes up;
Fig. 3 is a kind of valve of gas pipeline shown in Figure 2, but partial gear has wherein rotated to the position with valve closing.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of valve of gas pipeline 1 mainly is comprised of valve body 2, striking gear 11 and drive unit; Described valve body has the square valve core bar 3 that protrudes upward; Described striking gear 11 has one with jagged 15 partial gear 12, be connected with above the partial gear 12 and twist hand 13, be provided with the square through hole 14 of up/down perforation at partial gear 12 and stubborn hand 13, this square through hole 14 is complementary with above-mentioned square valve core bar 3; Described drive unit be one with the motor 21 of actuation gear 22, this actuation gear 22 is meshed with above-mentioned partial gear 12, the outside of this motor 21 is provided with terminal box, outer installment in terminal box has screening can 23, this screening can 23 can make between terminal box and the outside inflammable gas and be isolated, like this when not causing inflammable gas to be ignited during the generation electrical spark in the terminal box; Motor 21 is connected with the automatic control system (not shown) by circuit.Because this automatic control system is prior art, no longer is described in detail here.During installation, at first valve body 2 is connected on the lateral 4 with control valve unit, after this, striking gear 11 is connected on the square valve core bar 3 of valve body by its square through hole 14; Actuation gear 22 with motor is meshed (as shown in Figure 2) with the partial gear 12 of striking gear again.Need to prove that this motor 21 can be fixed on the main pipe of family's gas pipeline by support.Usually, this valve of gas pipeline 1 is in open mode, people can use existing control valve unit as usual, and when the user has forgotten to close gas stove switch because going out, at this moment can be with mobile phone to this automatic control system transmitted signal, automatic control system receives behind the signal thereupon closed motor 21 line switchings, the actuation gear 22 of motor 21 drives partial gear 12 with the direction rotation of square valve core bar 3 towards throttle down simultaneously, when valve is fully closed, breach 15 on the partial gear 12 of this moment just rotation to the position (as shown in Figure 3) relative with actuation gear 22, and this breach 15 breaks away from the engaging piece between partial gear 12 and the actuation gear 22, and then actuation gear 22 is dallied, meanwhile, automatic control system can stop operating motor by the open-circuit line switch.What need to further specify is just can reopen this valve switch with manually-operable.In addition, this automatic control system can have more function, and for example equal automatically starting motor cuts out valve switch when detecting gas leakage or breaking out of fire.
Claims (1)
