Claims

[Scope of utility model registration request]

A threaded part 3 for connecting to the neck of the cylinder 2 is provided at the lower end of the valve box 1, and a vertical through hole 7 and a horizontal through hole 7 that do not intersect with the vertical through hole 5 are provided in the valve box 1. A main valve chamber 9 having a main valve seat 8 is formed in the middle part of the main valve chamber 9, and a manually operated main valve 1 is formed in the upper half of the vertically oriented through hole 5.
0 is screwed into the state in which the main valve 10 is closed when seated on the main valve seat 8 and opened when separated from the main valve seat 8, and the left end of the horizontal through hole 6 is set as the gas outlet hole 12. A connecting part such as a pressure reducing valve is carved on the inner circumferential surface, and the right half of the horizontal through hole 6 has a wide diameter to form a residual pressure valve chamber 13 on the cylindrical peripheral wall surface, and the residual pressure valve chamber 13 and the main valve chamber 9 are connected to each other. are in communication through the intermediate hole 11, and a conical first valve seat part 14 that narrows toward the left is provided at the inner end of the residual pressure valve chamber 13, and a second female thread 15 is also provided on the inner peripheral surface of the outer end. In the residual pressure valve chamber 13, an inflow valve body 18 having a conical surface 16 on its left half outer circumference and a polygonal surface 17 on its right half outer circumference is placed in the residual pressure valve chamber 13, and the edge of the polygonal surface 17 slides on the circumferential wall surface of the residual pressure valve chamber 13. It is charged in a state in which it is movably in contact with the inflow valve body 18, and both ends are connected to the same inflow valve body 1.
A through hole 20 is formed in which the left half has a small diameter and the right half has a large diameter, and the peripheral wall of the large diameter portion 21 of the through hole 20 is a cylindrical surface, and the outer periphery is formed in the large diameter portion 21. is a bottomed cylindrical outflow valve body 23 with a polygonal surface 22,
The edge of the polygonal surface 22 is in slidable contact with the peripheral wall surface of the large diameter portion 21, and the opening edge 24 is in contact with the peripheral wall surface of the large diameter portion 21.
1 and the narrow diameter part 25 so as to be able to collide with each other, and a guide hole 27 is formed on the surface between the ridges in the peripheral wall of the outflow valve body 23 to communicate inside and outside. A cylindrical first end cover 28 is provided within the outer end of the large diameter portion 21.
A conical second valve seat 29 is seated on the inner periphery of the inner end of the first end cover 28, and the second valve seat 29 is seated on the outer surface of the bottom wall of the outflow valve body 23. A conical valve portion 30 is provided to close the through hole 20, and
A second end cover 31 is screwed onto the second female screw 15, and a first spring 32 that presses the inflow valve body 18 to the left is inserted between the second end cover 31 and the first end cover 28, and a stepped portion 26 and the outflow valve body 23, a second spring 33 is sandwiched between the outflow valve body 23 and the outflow valve body 23 to press the outflow valve body 23 to the right.
