The valve core rod (3) of the valve main body is sequentially connected with a striking gear (11) and an electric actuator (21). The striking gear (11) is provided with an incomplete gear (12) with a gap (15), a twisting handle (13) is fixedly connected with the upper portion of the incomplete gear (12), a square through hole (14) is arranged in the twisting handle (13) of the incomplete gear, and the lower end of the square through hole penetrates through the incomplete gear (12). The electric actuator (21) is an electric machine provided with a drive gear (22), and the drive gear is meshed with the incomplete gear (12). The electric actuator (21) is communicated with an automatic control system through a line.
Description
Technical field
The utility model relates to a kind of control valve unit, specifically relates to a kind of safe valve of gas pipeline that uses.
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 safe valve of gas pipeline that uses for above-mentioned deficiency, and the valve of gas pipeline of this use safety can make the use of gas pipeline safer.
The utility model is achieved in that a kind of safe valve of gas pipeline that uses, comprise valve body, this valve body has the valve core rod that its cross section of protruding upward is square, be provided with striking gear at valve core rod, be connected with Electric actuator on the described striking gear, described Electric actuator joins by circuit and automatic control system.
Described striking gear has one and is with partial gear jaggy, is connected with stubborn hand above the described partial gear, is provided with on hand square through hole twisting of partial gear, and the lower end of this square through hole connects described partial gear; On the relevant position of partial gear, also be provided with protruding axle; Described partial gear is connected on the above-mentioned valve core rod by square through hole.
Described Electric actuator is to be provided with actuation gear at a motor; This actuation gear is meshed with above-mentioned partial gear.
In sum, be connected with partial gear at the valve core rod of valve body, this partial gear is meshed with the actuation gear of Electric actuator, and Electric actuator is connected with automatic control system by circuit; Like this, when the user has forgotten to close gas stove switch because of inadvertent, when 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 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 that the utility model uses the valve of gas pipeline of safety;
Fig. 2 is the structural representation after the valve of gas pipeline combination of use safety shown in Figure 1;
Fig. 3 is the valve of gas pipeline of use safety 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, use the valve of gas pipeline 1 of safety mainly to be formed by valve body 2, striking gear 11 and Electric actuator 21; Described valve body has the valve core rod 3 that its cross section of protruding upward is square.Described striking gear 11 has one with jagged 15 partial gear 12, be connected with above the described partial gear 12 and twist hand 13, stubborn hand 13 at partial gear is provided with square through hole 14, and the lower end of this square through hole 14 connects described partial gear 12.Described Electric actuator (21) be one with the motor of actuation gear (22), this actuation gear (22) is meshed with above-mentioned partial gear (12); Described Electric actuator (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 (this valve body 2 can be connected on the lateral 4 in the upstream of existing control valve unit or downstream); After this, striking gear 11 is connected on the valve core rod 3 of valve body by its square through hole 14; Actuation gear 22 with Electric actuator 21 is meshed (as shown in Figure 2) with the partial gear 12 of striking gear again.Need to prove that this Electric actuator 21 can be fixed on the main pipe of family's gas pipeline by support.Usually, the valve of gas pipeline 1 of this use safety is in open mode, and people can use existing control valve unit as usual; And work as the user because of inadvertent, when when going out, having forgotten to close gas stove switch, at this moment can be with mobile phone to this automatic control system transmitted signal, automatic control system receives behind the signal thereupon closed electrical machine circuit switch, meanwhile, the actuation gear 22 of Electric actuator drives valve core rod 3 by 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, 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 just can finish with manually-operable if open this valve switch, the stubborn hand 13 that turns on the striking gear with hand during operation gets final product.Need to be further described above, 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.
