Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of spool in Fig. 1；
Fig. 3 is the sectional view of the A-A of Fig. 2.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to figure 1, figure 2 and figure 3, the multifunctional control valve of the utility model, including valve body 1 and spool 2, the valve body 1
Upper the same side is provided with low-pressure admission mouth 12, high pressure admission mouth 15 and pressure gauge and connects port 13, and pressure gauge connects the setting of port 13 and exists
It is connected between low-pressure admission mouth 12 and high pressure admission mouth 15 and with low-pressure admission mouth 12,12 He of relatively low pressure air inlet on valve body 1
The side of high pressure admission mouth 15 is respectively arranged with gas outlet 4, and 1 one end of valve body is provided with low pressure nut 3, the setting of 1 other end of valve body
There is high pressure nut 9, locking nut 10 is provided on high pressure nut 9,2 one end of spool is provided with valve core housing 11, corresponds to valve on spool 2
The end of core retainer plate 11 is provided with air guide face 7, and valve core housing 11 is connect with low pressure nut 3 by keyway, divides on valve core housing 11 and spool 2
Be not provided with guide ring and guide ring sealing ring, be provided with air guide channel on guide ring, air guide channel can with low-pressure admission mouth 12,
High pressure admission mouth 15 and gas outlet 4 communicate, and 2 other end of spool passes through high pressure nut 9 and locking nut 10, and spool 2 is corresponding high
The end of pressure nut 9 is provided with rotation 8, is provided with bulge on the spool 2, the conical surface is provided on bulge, the conical surface is close
The position of guide ring on valve rod, the air guide face 7 for corresponding to spool 2 in the valve body 1 is provided with valve body polytetrafluoro ring 14, the height
Sealing ring is provided between pressure nut 9 and spool 2, the guide ring sealing ring is made of polytetrafluoro material.
Spool 2 runs through valve body 1, and valve body 1 includes high-voltage end and low-pressure end, and high pressure admission mouth 15, low-pressure end is arranged in high-voltage end
Setting low-pressure admission mouth 12 and pressure gauge connect port 13, and 2 air guide face 7 of spool and valve body polytetrafluoro ring 14 are arranged in low-pressure end, valve
By threading action on spool 2, guide ring polytetrafluoro one end is provided with the conical surface, is socketed with guide ring on valve core housing 11 core retainer plate 11
5 and guide ring sealing ring 6, guide ring sealing ring 6 be stuck in low pressure nut 3 close to 11 conical surface of valve core housing, 11 other end of valve core housing
