Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
Embodiment one
As Fig. 2, Fig. 3 and overcurrent stop valve shown in fig. 5, including valve body and cutting assembly, cutting assembly are mounted on valve body
Interior, the valve body includes the retainer 2 of the air inlet flange 4 that gas enters and the interference fit installation of air inlet flange 4 and protects
The gas outlet support frame 1 of the interference fit installation of frame 2 is held, the cutting assembly includes release spring 5, steel ball 7, spool 8 and makes valve
The reset spring 10 that core 8 resets after cutting off gas, as shown in fig. 6, the spool 8 includes sequentially connected guiding upper plug head
81, flap 83 and guiding lower end cap 82, the spool 8 are an integral structure, and stronger structure is not in fracture, the flap
83 shape is hemispherical, is open towards the direction of air inlet flange 4, and the reset spring 10 is nested in guiding lower end cap 82
On, so that 10 one end of reset spring is resisted against on flap 83, the other end of reset spring 10 is resisted against on gas outlet support frame 1；
As shown in Fig. 2, the air inlet flange 4 is provided with the spring for placing release spring 5 and steel ball 7 far from 2 side of retainer
Hole 6, the release spring 5 are placed with steel ball 7 by one end of spool 8, and the release spring 5 blocks up 7 overhead of steel ball in guiding
The contact surface of first 81 surface, the guiding upper plug head 81 and steel ball 7 is bevel structure, convenient for resisting spool 8 and playing reset
Effect, the internal diameter of the air inlet flange 4 are greater than the internal diameter of the retainer 2；It is protected as shown in figure 5, the diameter of flap 83 is greater than
The internal diameter for holding frame 2 is less than the minimum diameter of air inlet flange 4.
As shown in Figure 3 and Figure 9, air inlet flange 4 is provided with the air inlet 12 of gas entrance；As shown in figure 8, gas outlet branch
Support 1 is provided with gas outlet 11, as shown in Fig. 2, the outer surface of retainer 2 is provided with seal groove, is provided in seal groove
Sealing ring 3, being provided with 3 sealing effect of sealing ring can be more preferable.
As shown in figure 8, at least provided with 2 vertically hung scrolls 13 on the gas outlet support frame 1, using 3 in the present embodiment
A vertically hung scroll 13 is evenly distributed on gas outlet support frame 1, and setting so had both been able to maintain gas outlet support frame 1 deformation occurs and is same
When to be able to maintain gas outlet 11 again sufficiently large；Air inlet flange 4, retainer 2, gas outlet support frame 1 and spool 8 material be
Plastics or metal, using injection molding or casting and forming；Air inlet flange 4, retainer 2, gas outlet support frame 1 and spool 8
Shaft centre line on one wire；Overcurrent cutting valve arrangement is simple, and air inlet is automatically closed when realizing overcurrent by cutting assembly, protects
It has demonstrate,proved with gas safety, while using two sides guiding setting, regardless of excessive much, spool 8 will not shift in valve body, valve
Valve 83 is designed to hemispherical, and sealing effect is more preferable.
In use, assuming that the overcurrent flow value of overcurrent stop valve is set as 1 cubic metre per hour, when the flow value of gas is low
Per hour in 1 cubic metre, gas enters in valve body from air inlet 12, successively passes through air inlet flange 4, retainer 2 and gas outlet
Support frame 1 is smoothly discharged from the gas outlet of gas outlet support frame 1 11；When the flow value of gas is more than 1 cubic metre, gas from
Air inlet 12 enters, per hour more than 1 cubic metre of the overcurrent flow value set due to flow, into the hemispherical interior gas of flap 83
Know from experience and push spool 8 mobile to 1 direction of gas outlet support frame, reset spring 10 acts on the power on spool 8 less than gas flow 1
Cubic meter acts on power on flap 83 per hour, until flap 83 and the chamfering 9 on retainer 2 are tangent, meanwhile, positioned at spring
Release spring 5 in hole 6 pushes up steel ball 7 to 8 direction of spool, keeps the sealing function of flap 83 and retainer 2, makes combustion gas can not
Pass through；After danger excludes, guiding lower end cap 82 is pressed to 4 direction of air inlet flange manually, reset spring 10, which plays, makes spool 8
Reset response.
