Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Domestic gas stopcock as shown in Figure 1, comprise valve body 1, valve body 1 inside is provided with spool (not shown), valve body is provided with the rotary knob rod 2 connecting, can change spool gas output size with spool, the connecting structure of rotary knob rod and spool is conventional structure, and spool is also conventional structure, repeats no more herein, in addition, also comprise:
The plastic presser plate 3 that be set on rotary knob rod 2, can move up and down under rotary knob rod 2 drives, this plastic presser plate 3 is enough large, and can cover in sensitive switch 4 completely, the liquid such as anti-sealing flow on sensitive switch 4; This plastic presser plate 3 is equipped with an external part 31 for pressing off sensitive switch 4, one is had for extruding the bump 312 of sensitive switch below external part, this lug boss 312 coordinates with sensitive switch 4, the position that plastic presser plate 3 is assemblied on rotary knob rod 2 meets: when plastic presser plate moves down under rotary knob rod drives, lug boss 312 can extrude and trigger this sensitive switch 4, and lug boss 312 can spherical in shape or hemisphere type or spheroid shape;
Be enclosed within rotary knob rod 2, be located at upper cover 5 above valve body, the side of this upper cover is extended a surface plate 51, and this surface plate is used for fixing sensitive switch 4.
Perforation 34 perisporium plastic presser plate 3 being used for wear rotary knob rod is provided with the opening slot 32 of some, on described rotary knob rod outer wall, then circumference is provided with a grooving 21, the perforation 34 of described plastic presser plate is just fastened in this grooving 21, and the punch inside diameter of plastic presser plate is greater than grooving external diameter is less than rotary knob rod external diameter; In plastic presser plate, perforation be plane up and down.During assembling, plastic presser plate 3 is enclosed within rotary knob rod from top to bottom, when plastic presser plate 3 is enclosed within rotary knob rod 2, plastic presser plate 3 applies a downward pressure, the opening slot 32 of perforation 34 perisporium of plastic presser plate 3 can be out of shape and opens, perforation 34 internal diameter is caused to become large, continu to press, plastic presser plate 3 can slip down in rotary knob rod grooving 21 along rotary knob rod 2, the bore a hole opening slot 32 of 34 perisporiums of plastic presser plate 3 no longer includes the extruding force of circumferencial direction, plastic presser plate 3 opening slot 32 restores to the original state under the natural restoring force effect of plastics, the internal diameter of the perforation 34 of plastic presser plate 3 is less than the external diameter of rotary knob rod 2, therefore plastic presser plate 3 is limited in the grooving 21 of rotary knob rod 2, the internal diameter of the perforation 34 of plastic presser plate 3 is greater than the external diameter of rotary knob rod grooving 21, rotary knob rod 2 can not block, can smooth rotation in the grooving 21 of plastic presser plate 3.
One limited post 311 is also set below the external part 31 of plastic presser plate 3, described upper cover 5 then arranges porose or groove 52 with this, described limited post is spacing to be arranged in this hole or groove, thus restriction pressing plate can only move up and down, and ensures pressure sensitive switch direction invariant position.
There is on the downside of described plastic presser plate 3 a tubulose lower extending end 33, described upper cover 5 also has a tubulose up extension end 53, described tubulose lower extending end 33 is just movably set in outside tubulose up extension end 53, thus plastic presser plate 3 and described upper cover are closely cooperated, play the guiding role, ensure that described plastic presser plate is rocked very little on rotary knob rod simultaneously, guarantee accuracy and the reliability of described plastic presser plate pressure sensitive switch.
When rotary knob rod 2 press down rotate counterclockwise time, the plastic presser plate 3 be stuck in rotary knob rod grooving 21 is subject to downward pressure, moves down with rotary knob rod 2, and in plastic presser plate 3, bump 312 is nearest with sensitive switch 4, presses off sensitive switch and realizes ignition function.The limited post 311 of plastic presser plate 3 moves up and down in the hole of upper cover 5 or groove 52, ensures that plastic presser plate 3 can not circular-rotation, and the external part 31 of restriction plastic presser plate 3 is all the time in the direction coordinated with sensitive switch 4.The tubulose lower extending end 33 of plastic presser plate 3 closely cooperates with the tubulose up extension end 53 of described upper cover 5, play the guiding role, and ensures that plastic presser plate 3 is rocked when rotary knob rod 2 moves up and down very little, guarantees that described plastic presser plate 3 presses accuracy and the reliability of sensitive switch 4.Like this, only need upper cover and pressing plate just can realize the function of pressing sensitive switch 4 to light a fire, and originally compared with 5 to 6 parts, cost need have been saved, simple and reliable for structure, and do not need to use jump ring, easily realize Automated assembly.Automatically reseting after pressing down as rotary knob rod 2 is existing routine techniques, that is: the spring of valve core inside realize rotary knob rod 2 press down after automatically reset.
