Description
Technical field
The utility model relates to thermoelectricity field, particularly relates to the gas exhausting valve of dryer in a kind of boiler ash-transmission system.
Background technique
In the boiler ash-transmission system of thermal power plant, the defeated grey mode of general employing malleation concentrated phase, is become with its equipment for after-treatment drier by air compressor, and during work, the air that air compressor produces enters dryer, then is delivered to user after being processed by dryer.Wherein air compressor and dryer are that cell value is arranged, the resistance of air of each dryer is different, make the flow of the pressurized gas flowing through each dryer also different, when the air mass flow of dryer changes, the valve of its entrance can cause the air inlet in it to switch valve plate akinesia because air mass flow is large, thus gas is drained in air by outlet pipe by valve cause exhaust failure.
Model utility content
The purpose of this utility model is the gas exhausting valve that will provide a kind of dryer, carries to avoid the gas of the air mass flow variable effect dryer of air compressor.
Especially, the utility model provides a kind of gas exhausting valve of dryer, comprises hollow valve body, and the suction tude, outlet pipe and two pneumatic tubes that are connected respectively with described valve body;
Outlet chamber and exhaust cavity is independently provided with in described valve body;
The opposite end of described outlet chamber is provided with air outlet, two described air outlets are connected with two described pneumatic tubes respectively, axostylus axostyle is connected with between two described air outlets, described axostylus axostyle is provided with the valve plate moved back and forth along described axostylus axostyle by gas uninterrupted, and described suction tude is connected with the middle part of described outlet chamber;
The two ends of described exhaust cavity are connected with two described pneumatic tubes respectively and are provided with the spring seal door according to the movement of gas pressure size, and described outlet pipe is connected to the middle part of described exhaust cavity;
In described suction tude, installation is lost gas and is driven pneumatic valve, and described mistake gas is driven pneumatic valve and is connected with described outlet pipe by bypass tube, and described mistake gas opens pneumatic valve controls described suction tude break-make according to the gas pressure size of described outlet pipe.
Further, described outlet pipe is provided with baffler away from one end of described valve body.
Gas exhausting valve of the present utility model drives pneumatic valve owing to having installed mistake gas in suction tude, therefore the air mass flow variable effect by suction tude can be avoided when dryer is vented, make its air inflow be reduced to below rating value, and automatically recover the air inlet of air compressor after dryer finishing switching.This programme installs simple and cost is low and the transformation decreased existing control system.
According to hereafter by reference to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference character identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
Fig. 1 is the gas exhausting valve structural representation according to the utility model embodiment;
Fig. 2 is the gas exhausting valve scheme of installation according to the utility model embodiment.
Embodiment
As shown in Figure 1, 2, gas exhausting valve 100 of the present utility model comprises hollow valve body 10 in general manner, and the suction tude 20, outlet pipe 30 and two pneumatic tubes 40 that are connected respectively with valve body 10.Outlet chamber 11 and exhaust cavity 12 is independently provided with in valve body 10.Air outlet 13 is respectively arranged with at the opposite end of outlet chamber 11, two air outlets 13 are connected with two pneumatic tubes 40 respectively, between two air outlets 13, be connected with axostylus axostyle 16, axostylus axostyle 16 is movably installed with valve plate 15, this suction tude 20 is connected with the middle part of outlet chamber 11.The two ends of this exhaust cavity 12 are connected with two pneumatic tubes 40 respectively and are provided with the spring seal door 14 according to the movement of gas pressure size, and outlet pipe 30 is connected to the middle part of exhaust cavity 12.In suction tude 20, installation is lost gas and is driven pneumatic valve 50, and this mistake gas is driven pneumatic valve 50 and is connected with outlet pipe 30 by bypass tube 51, and the switch that mistake gas drives pneumatic valve 50 affects by the size of gas pressure in bypass tube 51.
Under working state, dryer is when switching, gas in gas exhausting valve 100 is entered after exhaust cavity 12 promotes spring seal door 14 by pneumatic tube 40 and is discharged by outlet pipe 30, gas pressure now can reach 0.4Mpa, this gas can enter mistake gas by bypass tube 51 and drive pneumatic valve 50 while being discharged by outlet pipe 30, and suction tude 20 is closed by the pneumatic door that promotion mistake gas drives pneumatic valve 50; This gas its pressure in the discharge process of outlet pipe 30 diminishes gradually with drain time, until vanishing when gas discharging is complete, this discharge process approximately continues 2 to 3 seconds.In this discharge process, because suction tude 20 is in closed condition, the unchanged or variable quantity of the air mass flow therefore in air-inlet cavity 11 is less than rating value, so the movement of valve plate 15 on axostylus axostyle 16 can not stop at certain one end by the impact of air mass flow.When dryer switches complete, the pneumatic door also making gain and loss gas drive pneumatic valve 50 without gas in outlet pipe 30 runs out of steam, thus automatically enters former working state after opening suction tude 20.The scheme of the present embodiment makes dryer separate with the process of supplying gas of air compressor when switching, and forms two independently working procedure and can perfection linking.This programme does not need the control system that increase is relevant, and the source of the gas of pneumatic valve 50 is opened in the pulse exhaust utilizing dryer to produce when switching as mistake gas, also solve and lose the closedown power that gas drives pneumatic valve 50.After adopting the scheme of the present embodiment, how ash-transmission system changes the normal work that all can not affect dryer simultaneously.
Further, for reducing dry sound during outlet pipe 30 exhausting air, on outlet pipe 30, baffler 31 can be installed.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
