Abstract
The invention discloses a gas pipeline valve for safety in use, comprising a valve body, wherein the valve body is provided with a valve core rod (3) which extends upwards, and the cross section of the valve core rod (3) is square, the valve core rod (3) of the valve body is connected with a turning device (11) and an electric device (21) in sequence; the turning device (11) is provided with an incomplete gear (12) with a gap (15), a twist hand (13) is fixed on the incomplete gear (12), a square through-hole (14) is arranged on the twist hand (13) of the incomplete gear, the incomplete gear (12) is linked with the lower end of the square through-hole, a convex shaft (15) is also arranged at the corresponding position of the incomplete gear. The electric device (21) is a motor with a driving gear (22), wherein the driving gear is meshed with the incomplete gear (12); the electric device (21) is communicated with an automatic control system through a line.
Description
Technical field
The present invention relates to a kind of control valve unit, specifically relate to a kind of valve of gas pipeline safe in utilization.
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 very big potential safety hazard like this; In actual life, often there is the people when going out, to have forgotten to turn off gas stove switch just in use because of inadvertent, cause the utensil quilt dry combustion method for a long time on the gas cooker, be easy to the initiation fire accident like this.
Summary of the invention
The present invention is directed to above-mentioned deficiency a kind of valve of gas pipeline safe in utilization is provided, this valve of gas pipeline safe in utilization can make the use of gas pipeline safer.
The present invention is achieved in that a kind of valve of gas pipeline safe in utilization; Comprise valve body; This valve body has the valve core rod that its cross section of upwards stretching out is square; On valve core rod, be provided with striking gear, be connected with Electric actuator on the said striking gear, said Electric actuator joins through circuit and automatic control system.
Said striking gear has a partial gear that has breach, is connected with stubborn hand above the said partial gear, is provided with square through hole on hand twisting of partial gear, and the lower end of this square through hole connects said partial gear; On the relevant position of partial gear, also be provided with protruding axle; Said partial gear is connected on the above-mentioned valve core rod through square through hole.
(22) motor, this actuation gear (22) is meshed with above-mentioned partial gear (12); Said Electric actuator (21) is connected with the automatic control system (not shown) through circuit.Because this automatic control system is an existing technology, does not remake detailed description here.During installation, at first valve body 2 is connected on the lateral 4 that has control valve unit (this valve body 2 can be connected on the lateral 4 in the upper reaches or downstream of existing control valve unit); After this, striking gear 11 is connected on the valve core rod 3 of valve body through its square through hole 14; Again with the actuation gear 22 of Electric actuator 21 be meshed with the partial gear 12 of striking gear (as shown in Figure 2).Need to prove that this Electric actuator 21 can be fixed on the main pipe of family's gas pipeline through support.Usually, this valve of gas pipeline safe in utilization 1 is in open mode, and people can use existing control valve unit as usual; And when the user has forgotten to close gas stove switch because of inadvertent, when going out; At this moment can send signal to this automatic control system with mobile phone; Automatic control system receives closed thereupon motor lines way switch behind the signal, and meanwhile, the actuation gear 22 of Electric actuator drives valve core rods 3 through partial gear 12 and rotates towards the direction of throttle down; When valve is fully closed; This moment, the breach 15 on the partial gear 12 will rotate to the position (as shown in Figure 3) relative with actuation gear 22, and this breach 15 can make the engaging piece between partial gear 12 and the actuation gear 22 break away from, and then actuation gear 22 is dallied; Meanwhile, automatic control system can stop operating motor by the open-circuit line switch.Need to prove that must will use manually-operable to accomplish if open this valve switch, the stubborn hand 13 that turns on the striking gear with hand during operation gets final product.Need be to the explanation further of above do, this automatic control system can have more function, for example when detecting gas leakage or breaking out of fire equal automatically starting motor with valve closing.
Said Electric actuator is that a motor is provided with actuation gear; This actuation gear is meshed with above-mentioned partial gear.
In sum, on the valve core rod of valve body, be connected with partial gear, this partial gear is meshed with the actuation gear of Electric actuator, and Electric actuator is connected with automatic control system through circuit; Like this; When the user has forgotten to close gas stove switch because of inadvertent, when going out; At this moment can send signal to this automatic control system with mobile phone, 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 take place, 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 the present invention's valve of gas pipeline safe in utilization;
Fig. 2 is the structural representation after valve of gas pipeline safe in utilization shown in Figure 1 makes up;
Fig. 3 is a valve of gas pipeline safe in utilization shown in Figure 2, but partial gear has wherein rotated to the position with valve closing.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
To shown in Figure 3, valve of gas pipeline 1 safe in utilization mainly is made up of valve body 2, striking gear 11 and 21 of Electric actuators like Fig. 1; Said valve body has the valve core rod 3 that its cross section of upwards stretching out is square.Said striking gear 11 has a partial gear 12 that has breach 15; Be connected with above the said partial gear 12 and twist hand 13; The stubborn hand 13 of partial gear is provided with square through hole 14, and the lower end of this square through hole 14 connects said partial gear 12; On the relevant position of partial gear 12, also be provided with protruding axle 15.Said Electric actuator (21) is one and has actuation gear.
