The limiting part 9 and the shifting rod 18 can be in the same axial direction of the valve rod assembly, and can also have any included angle.
As shown in fig. 1, 2 and 6, the limiting seat 12 is a rectangular plate having a mounting hole 13, and extends downward from two corresponding sides of the rectangular plate and then extends outward to form a structure.
The mounting hole 13 of spacing seat 12 forms the spacing arm of circumference from edge downwardly extending, and the height that highly is less than spacing seat 12 of spacing arm, and has spacing groove 14, and mainly used consolidates valve rod assembly, prevents that it from rocking at will, and the installation is infirm to influence the use.
The limiting seat 12 can be in other structures and shapes, so that the valve rod assembly and the connecting rod 15 can be fixed, and the sliding of the first valve rod 7 relative to the second valve rod 10 is not influenced.
In this embodiment, when the valve rod assembly is in the state of fig. 1, the limiting portion 9 on the first valve rod 7 is located below the limiting arm, and is not embedded into the limiting groove 14 of the limiting seat 12, so the first valve rod 7 can drive the second valve rod 10 to rotate at will, the limiting portion 9 rotates at will along with the first valve rod 7, the shift lever 18 rotates along with the second valve rod 10 and drives the valve core 19 to rotate, through the cooperation of the vent hole and the gas channel 2 arranged on the valve core 19, the gas flow rate in the gas channel 2 can be adjusted, at this moment, the first adjusting hole 5 is located in the gas channel 2, and is in an open state, and the second adjusting hole 6 is closed.
As shown in fig. 2, when rotating first valve rod 7 to suitable angle, spacing portion 9 corresponds with spacing groove 14 position along with rotating, connecting rod 15 butt is in the through-hole of spacing portion 9, lift up first valve rod 7 this moment, spacing portion 9 upwards slides in spacing hole 11 and spacing groove 14, can drive connecting rod 15 and rise, and then drive gas circuit adjusting device 4 and rise, this moment because gas circuit adjusting device 4 rises and leads to first regulation hole 5 to leave gas passageway 2, second regulation hole 6 rises simultaneously and gets into gas passageway 2, first regulation hole 5 seals this moment, second regulation hole 6 opens, realize the flow regulation of giving vent to anger.
When the valve is in the state of fig. 2, at this time, since the limiting portion 9 of the first valve rod 7 is embedded into the limiting groove 14 of the limiting seat 12, the first valve rod 7 cannot rotate, and only when the first valve rod 7 is pressed downward to return to the state of fig. 1, the first valve rod 7 can rotate.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
