Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Shown in Fig. 2-6.
A kind of safe self-regulated nodal pattern dual gas supply pressure maintaining valve, its profile comprise upper valve body 1 and following valve body 5 like Fig. 2, shown in 3; Following valve body is provided with low-pressure gas source inlet 10 and high-pressure air source inlet 11, in low-pressure gas source inlet 10 and the high-pressure air source inlet 11 seal bar 8 is installed all, turns round not like Fig. 4; Seal bar 8 is made up of the body of rod 801, sealing shaft shoulder ring 802 and seal ring 803, and the body of rod 801 passes air inlet ring 16 and gas source connector 9 offsets, and seal ring 803 is fixed on the seal ring 802 and offsets with the end face of air inlet ring 16; One end of Packing spring 15 offsets with sealing shaft shoulder ring 802 so that seal on the end face that shaft shoulder ring 802 is against air inlet ring 16 all the time, and the other end of Packing spring 15 offsets with the inwall of following valve body 5, and air inlet ring 16 seals in the air source inlet end that is installed in correspondence; The described body of rod 801 is provided with axial notch; Like Fig. 5, shown in 6, the offseting of the seal bar 8 of installing in the described low-pressure gas source inlet 10 with gas source connector 9, the other end contacts with an end of pressure pin 7; Be equipped with on the seal bar 8 and make seal bar 8 be against the Packing spring 15 on the suction port all the time; The other end of pressure pin 7 is sleeved on valve rod 12 and is arranged on the end of following valve body 5 and with the secondary pressure adjusting spring 6 that is sleeved on the valve rod 12 and offsets, and the other end of valve rod 12 passes vent 13 and links to each other with clamping plate, and it is continuous that clamping plate are fixed on epithelium 3 again; Valve rod 12 also can directly be fixed on the epithelium 3; Seal ring 4 is installed on the vent 13, and seal ring 4 is fixed on the sealing skeleton, and sealing skeleton 3 is fixed on the vent hole wall; Epithelium 3 is fitted between upper valve body 1 and the following valve body 5, and the one side that epithelium 3 is arranged in upper valve body 1 offsets with an end of main spring 2, and the other end of main spring 2 and adjusting pressuring knob 14 offset, adjusting pressuring knob 14 through the screw thread spinning in upper valve body 1, as shown in Figure 5; In the described high-pressure air source inlet 11 seal bar 8 is installed also, high-pressure air source inlet 11 is connected with vent 13 through the inner passage in the following valve body 5.
Working principle of the present invention is:
1, when not inserting gas source, seal bar 8 is at the effect lower seal inlet of spring force, and combustion gas can not leak outside.Fig. 4, shown in 5.
2, when inserting combustion gas, because the screw-in of joint is opened gas circuit thereby promote seal bar 8.
Two inlets (as shown in Figure 2) are arranged on 3, on the valve body, when inserting low-pressure fuel gas, (screw in gas source connector 9 in the low-pressure gas source inlet), seal bar 8 can promote pressure pin 7, raises secondary pressure adjusting spring 6; Thereby during pressure maintaining valve work, the acting in conjunction by main pressure regulator spring 2 and secondary pressure adjusting spring 6 then exports gaseous-pressure smaller [P*S=(K1-K2) * △ X]; Wherein, P is an outlet pressure, and S is the epithelium inner area; K1 is main spring elasticity coefficient, and K2 is the auxiliary spring elasticity coefficient, and △ X is a decrement.When inserting high-pressure gas (when screwing in gas source connector 9 in the high-pressure air source inlet 11 among Fig. 2; Owing in high-pressure air source inlet 11, pressure pin 7 is not installed, therefore can not make secondary pressure adjusting spring 6 lift work on having, have only the main pressure regulator springs; P*S=K1* △ X then, outlet pressure is bigger.
The present invention does not relate to all identical with the existing technology existing technology that maybe can adopt of part and realizes.
