Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in FIG. 1 to 3, the fuel gas plug valve in the present embodiment includes valve body 1, spool 2, motor 3 and solenoid valve 4,
1 inside of valve body has valve chamber, and the air outlet 18 communicated with valve chamber, inlet channel 11, outer shroud outlet passageway are offered on valve body 1
13rd, the branched gas channel 12 that inner ring outlet passageway 14 and both ends communicate respectively with valve chamber and inner ring outlet passageway 14.Air outlet 18
Multiple plug valves can be connected as one, when used aloned can be sealed with plug.
Spool 2 is revolvably interior set on the valve chamber of valve body 1 and can adjust outer shroud outlet passageway 13 and inner ring outlet passageway 14
Flow.
Motor 3 is set on valve body 1 and power output end is drivingly connected with spool 2；Solenoid valve 4 is set on valve body 1, for opening
Close the air inlet of 26 bottom of venting cavity.
With reference to shown in Fig. 4,2 middle part of spool has venting cavity 26, and the air inlet of 26 bottom of venting cavity is connected with valve chamber, valve
2 side wall of core offers what is ventilated with the outer shroud fire hole 21 of the cooperation ventilation of outer shroud outlet passageway 13, with the cooperation of inner ring outlet passageway 14
It is inner ring fire hole 22, equal with the steady fire hole 23 of the cooperation ventilation of branched gas channel 12 and with outer shroud outlet passageway 13 and inner ring outlet passageway 14
The air slot 24 of ventilation can be coordinated, outer shroud fire hole 21, inner ring fire hole 22 and steady fire hole 23 are communicated with venting cavity 26, air slot 24
Inside offer the venthole 25 communicated with venting cavity 26.Air slot 24 is arranged in the shape of a spiral on 2 side wall of spool.
Solenoid valve 4 and motor 3 are respectively arranged on the both sides of valve body 1, solenoid valve 4 have one it is electric after the compression bar 41 that can bounce back,
The end of the compression bar 41 is equipped with the gasket seal 42 that can open and close 26 bottom air inlet of venting cavity.Energy after dead electricity is arranged on compression bar 41
Driving gasket seal 42 seals the resetting spring 43 of 26 bottom air inlet of venting cavity.
Motor 3 and the driving setting of spool 2 are as follows：The power output end of motor 3 has ring gear 31, and spool 2 is equipped with
One valve rod 5 forms the gear teeth 51 being adapted to ring gear 31 on the valve rod 5.
The keying end of solenoid valve 4 is directly arranged in the inlet end of spool 2, such 1 internal gas access of valve body simplifies, distance
Shorten, while gas is only needed by a solenoid valve 4, without repeatedly passing through, airflow pressure losses substantially reduce, flow
Difference variation also reduces.
When adjusting flow, inner ring fire hole 22 coordinates with inner ring outlet passageway 14, and steady fire hole 23 coordinates with branched gas channel 12,
Realize the circulation of inner ring gas, when further increasing adjusting angle, inner ring fire hole 22 is no longer connected with inner ring outlet passageway 14,
Outer shroud fire hole 21 and air slot 24 are connected with outer shroud outlet passageway 13, meanwhile, air slot 24 also connects with inner ring outlet passageway 14
It is logical, it realizes the intercommunication of outer shroud outlet passageway 13 and inner ring outlet passageway 14, changes while realizing flow.That is the gas of inner and outer ring
Distribution is then flowed out due to the jet size that outlet passageway matches inside and outside valve body than row, realizes that the gas flow variation of inner and outer ring becomes
Gesture is identical.
In the present embodiment, it is interior circulation tune that flow regulating function, which in the adjusting angle of motor is 90 ° of existing plug valves,
Section, 90 ° to 135 ° are adjusted in synchronism for inside and outside circulation.The maximal regulated angle of valve body is 130 °, changes the flow of existing valve body
Regulative mode (during the adjusting of existing valve body 0-90 ° of firepower by small to maximum, 90 ° -- start again by firepower by adjusting greatly after 180 °
Small fire is saved, the firing point repeated occurs in such regulative mode, and it is big to adjust angle), such adjusting advantage is valve
The adjusting angle of core is small so that motor reaches required angle in the short period, and raising instruction issuing is completed same with flow-rate adjustment
Step rate.
Following table is the Spool rotating flow in process variation of plug valve in the present embodiment.
Corresponding curve graph is as shown in Figure 5.
