Abstract
The utility model discloses a kind of three position four-way directional control valves of included purging port, including valve body, partition is wherein equipped in the valve body, through-hole there are three being set on the partition, cylinder is correspondingly provided on the valve body above the through-hole, the bottom of the cylinder is connected with valve plate, is correspondingly provided with port on the valve body of the through-hole side, and gas outlet is equipped on the valve body below the partition；Demarcation plate is equipped between the through-hole, the through-hole includes combustion gas through-hole, smoke ventilator and purging through-hole；When combustion gas commutation; first closing gas valve plate; blowback valve plate is opened again; the combustion gas in reversing blind zone pipeline stove is blown into using the flue gas (or nitrogen) of blowback to burn; last opened smoke-discharging valve plate simultaneously closes off purging valve plate, discharges fume, so as to avoid the waste of combustion gas in pipeline; the discharge of pernicious gas is also reduced simultaneously, protects environment.
Description
Technical field
The utility model relates to coal gas Regenerative Combustion System reversal valve, especially a kind of included purging of included purging port
The three position four-way directional control valve of port.
Background technique
It in existing threeway combustion gas reversal valve, is made of in total three mouths, respectively gas port, flue gas mouth and outlet
Mouthful, when burning, it is necessary first to gas port to be opened, combustion gas is entered in burner hearth by gas outlet burns, when needing to discharge fume,
Flue gas mouth is opened, and the flue gas in burner hearth excludes after passing through gas outlet from flue gas mouth, however in actual operation, gas valve and burner hearth
Between have one section of gas pipeline, this allows for carrying out combustion gas and when the commutation of flue gas, the combustion gas in gas pipeline (is changed
To blind area) it is just excluded in the case where not burnt, the waste of combustion gas, but also serious influence are not only caused in this way
Environment.
Utility model content
The technical assignment of the utility model is and to provide a kind of included purging port for the above the deficiencies in the prior art
Three position four-way directional control valve.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of 3-position 4-way of included purging port
Reversal valve, including valve body are set on the partition there are three through-hole, wherein being equipped with partition in the valve body in the through-hole
Cylinder is correspondingly provided on the valve body of top, the bottom of the cylinder is connected with valve plate, corresponding on the valve body of the through-hole side
Equipped with port, gas outlet is equipped on the valve body below the partition.
It is further improved: being equipped with demarcation plate between the through-hole, the through-hole includes combustion gas through-hole, smoke ventilator and blows
Sweep through-hole.
The advantages of the utility model: before carrying out combustion gas commutation, it will first purge the blowback valve plate on through-hole and open, using anti-
Blow his (flue gas or nitrogen) combustion gas in gas pipeline is all advanced into burner hearth, then turn off blowback valve plate, simultaneously
Opened smoke-discharging valve plate excludes flue gas, so as to avoid the waste of combustion gas in pipeline, while also reducing the discharge of pernicious gas,
Protect environment.
Detailed description of the invention
Fig. 1 is the master map of the utility model.
Fig. 2 is the utility model top view.
Fig. 3 is the utility model side view.
Specific embodiment
The utility model is described below with reference to the accompanying drawings of the specification.
As shown, a kind of three position four-way directional control valve of included purging port, including valve body 1, wherein in the valve body 1
Equipped with partition 3, is set on the partition 3 there are three through-hole 4, be correspondingly provided with cylinder 6, institute on the valve body 1 above the through-hole 4
The bottom for stating cylinder 6 is connected with valve plate 5, port 7 is correspondingly provided on the valve body 1 of 4 side of through-hole, under the partition 3
The valve body 1 of side is equipped with gas outlet 2.
It is further improved: being equipped with demarcation plate 8 between the through-hole 4, the through-hole 4 is logical including combustion gas through-hole 41, flue gas
Hole 42 and purging through-hole 43.
Its working principle is that: firstly, port 7 includes gas port 71, flue gas mouth 72 and blowback port 73, cylinder 6 includes combustion
Gas cylinder 61, flue gas cylinder 62 and blowback cylinder 63, when burning, combustion gas cylinder 61 is shunk, so that combustion gas through-hole 41 is opened, combustion gas
Burning is completed by entering burner hearth after combustion gas through-hole 41 and gas outlet 2, until needing to take a breath, combustion gas cylinder 61 extends,
Valve plate 5 is driven to be closed combustion gas through-hole 41, then blowback cylinder 63 is shunk, and purging through-hole 43 is opened, blowback air enters combustion gas
In pipeline, the combustion gas rested in gas pipeline originally is allowed to enter in burner hearth, carry out full combustion, finally controls blowback cylinder
Purging through-hole 43 is closed in 63 elongations, while flue gas cylinder 62 is shunk, and smoke ventilator 42 is opened, the cigarette being located in burner hearth in this way
Gas is avoided in gas pipeline in whole process well by being excluded behind gas outlet 2 and smoke ventilator 42 by flue gas mouth 72
The case where combustion gas just excludes under no progress combustion case.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
