Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
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,
There is valve chamber inside valve body 1, offer the air outlet 18 communicated with valve chamber, inlet channel 11, outer ring outlet passageway on valve body 1
13, the branched gas channel 12 that inner ring outlet passageway 14 and both ends are communicated with valve chamber and inner ring outlet passageway 14 respectively.Air outlet 18
Multiple plug valves can be connected as one, when used aloned can be sealed with plug.
Spool 2 revolvably in the valve chamber of valve body 1 and is adjustable outer ring outlet passageway 13 and inner ring outlet passageway 14
Flow.
Motor 3 is set on valve body 1 and power output end and spool 2 are drivingly connected；Solenoid valve 4 is set on valve body 1, for opening
Close the air inlet of 26 bottom of venting cavity.
As shown in connection with fig. 4, there is venting cavity 26, the air inlet of 26 bottom of venting cavity is connected to valve chamber, valve in the middle part of spool 2
2 side wall of core, which is offered with the outer ring fire hole 21 of the cooperation ventilation of outer ring outlet passageway 13, with inner ring outlet passageway 14, cooperates ventilation
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 ring outlet passageway 13 and inner ring outlet passageway 14
It is able to cooperate the air slot 24 of ventilation, outer ring 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 two 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 power loss is arranged on compression bar 41
Driving gasket seal 42 seals the reset spring 43 of 26 bottom air inlet of venting cavity.
The driving of motor 3 and spool 2 is provided that 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 opening and closing 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 are substantially reduced, flow
Difference variation also reduces.
When adjusting flow, inner ring fire hole 22 and inner ring outlet passageway 14 cooperate, and steady fire hole 23 cooperates 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 to inner ring outlet passageway 14,
Outer ring fire hole 21 and air slot 24 are connected to outer ring outlet passageway 13, meanwhile, air slot 24 also connects with inner ring outlet passageway 14
It is logical, it realizes the intercommunication of outer ring outlet passageway 13 and inner ring outlet passageway 14, changes while realizing flow.That is the gas of inner and outer ring
Distribution then since the jet size that outlet passageway matches inside and outside valve body is than column outflow, 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 is 90 ° of existing plug valves in the adjusting angle of motor,
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 (when 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, duplicate firing point 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, improves instruction issuing with flow and adjusts the same of completion
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.
