Description of the Related Art A regulator of this type generally comprises an on-off valve for opening and closing a flow path between a primary pressure inlet and a secondary pressure outlet, and a valve for controlling the pressure of the secondary pressure outlet and the spring pressure. An operating piston body that operates by receiving the differential pressure and closes the on-off valve when the secondary discharge pressure is higher than the spring pressure and opens the on-off valve when the secondary discharge pressure is low. This regulator further has a pressure adjusting mechanism for adjusting the spring pressure exerted on the working piston body in order to adjust the take-out secondary pressure, but the conventional pressure adjusting mechanism is provided between the working piston and the spring receiving piston.
A compression spring that applies a spring pressure to the working piston is inserted, and the spring receiving piston is moved toward and away from the working piston by a feed screw mechanism. The conventional pressure adjusting mechanism using this feed screw mechanism has the advantage that precise pressure adjustment is possible, but on the other hand, it takes a long time to adjust the pressure, and is not suitable for the purpose of use in which the constant pressure is repeatedly set. there were.

6a is separated from the valve seat 14a. Therefore, the primary pressure inlet 12 and the secondary pressure outlet 13 communicate with each other. On the other hand, when the working piston body 18 rises and separates from the valve rod 16 due to the pressure in the secondary pressure chamber 20 (secondary pressure outlet 13), the taper valve portion 16 a of the valve rod 16 is moved by the force of the compression spring 17.

とで、調圧レベルの表示ができる。According to the simplified regulator having the above-described structure, the pressure adjusting knob 26 is rotated to change the contact position between the push pin member 30 and the cam surface 28, so that the outlet pressure of the secondary pressure outlet 13 is changed. Can be adjusted. That is, when the push pin member 30 is brought into contact with the high flat surface portion 28a, the spring receiving piston 21 is the most actuated piston body 18
The pressure of the compression coil spring 22 acting on the working piston 18 in the state approaching to the side is the highest, and thus the pressure taken out to the secondary pressure outlet 13 is the highest.
On the contrary, when the push pin member 30 is brought into contact with the low plane portion 28c, the spring receiving piston 21 is most moved by the operating piston body 18
, And the pressure of the compression coil spring 22 acting on the working piston 18 is the smallest, and therefore the pressure taken out to the secondary pressure outlet 13 is the lowest. If the push pin member 30 is brought into contact with any part of the inclined surface 28b, the removal pressure between the maximum pressure and the minimum pressure can be obtained. Further, by adjusting the screwing position of the push pin member 30 with the pressure adjustment knob 26 and adjusting the amount of protrusion of the push pin member 30 toward the spring receiving piston 21, fine adjustment of the set pressure is also possible. If the rotation range of the pressure adjustment knob 26 is limited to less than one rotation by the stopper pin 31, adjustment becomes easier, and by providing an index between the upper housing 11a and the pressure adjustment knob 26, the pressure adjustment level can be reduced. Can be displayed.

置に戻る。FIGS. 7 and 8 show a third embodiment of the present invention. This embodiment is an embodiment in which the pressure is adjusted by raising the pressure adjustment knob 26B, contrary to the second embodiment in which the pressure is adjusted by depressing the pressure adjustment knob 26A. Pressure adjustment knob 2
A compression spring 44 for urging the pressure adjustment knob 26B in a downward direction is inserted between the knob support seat 34 and the knob support seat 6B.
At the lowered position of the pressure adjustment knob 26B shown in FIG. 7, the lock ball 39 is held between the lock groove 45 formed in the upper housing 11a and the lock groove 38 of the star wheel 37, and the rotation of the pressure adjustment knob 26B is stopped. Locked. When the pressure adjusting knob 26B is pulled up from this state against the force of the compression spring 44 and is brought into the state of FIG. 8, the lock ball 39 is released from the lock groove 38, and the rotation of the pressure adjusting knob 26B becomes free. Therefore, the pressure adjustment operation can be performed by rotating the pressure adjustment knob 26B as described above. When the pressure adjustment knob 26B is released after the pressure adjustment, the lock position shown in FIG. Return to
