Abstract
The utility model relates to a baffle plate type wind-pressure switch. The wind-pressure switch comprises a support, wherein a wind-pressure baffle plate is hinged to the support, a voltage adjusting screw is connected with an angle plate end of the wind-pressure baffle plate, the voltage adjusting screw matches with a homing voltage-adjusting spring arranged on the support, and a touch plate of a microswitch matches with an angle plate end surface of the wind-pressure baffle plate. During installation, the wind-pressure baffle plate is directly inserted into an air outlet of a blower from a side part of the blower, so that wind pressure directly blows the wind-pressure baffle plate; with the effect of the wind pressure, one end of the wind-pressure baffle plate tilts upwards along a hinge joint, and the angle plate end of the wind-pressure baffle plate pushes the touch plate of the microswitch downwardly, so that the microswitch is switched on to output wind-pressure signals. The voltage adjusting screw is connected with the angle plate end of the wind-pressure baffle plate, and the voltage adjusting screw matches with the homing voltage-adjusting spring arranged on the support, so that the pressure of the adjusting spring can be used to adjust required control wind pressure. The baffle plate type wind-pressure switch has the advantages including simple structure, convenient adjustment, low cost, stable and reliable motions, long service life, free of environmental influence, and free of replacement.
Description
Technical field
The utility model belongs to blast switch, is a kind of baffle-type blast switch.
Background technology
Existing gas heater, burnt gas wall hanging furnace etc. are equipped with the gas-fired equipment of blower fan, in order to guarantee all essential cover wind pressure monitoring device of installing in addition of combustion completion, are used to monitor the blast operating mode, to guarantee the needed enough blast of burning.At present; Wind pressure monitoring device on the combustion gas tool blower fan all is the diaphragm type structure; Need use two sebific ducts to be connected during installation with the blast sampler in blower fan exit; Promote or spur the barrier film of wind measuring device again through the blast of sebific duct transmission, drive is contained in the outside switch of wind measuring device signal is exported.This wind pressure monitoring installation cost is high, and failure rate is high, particularly in the winter time, because of the condensed water in the flue gas can often enter in the sebific duct, makes wind measuring device detect the malfunctioning machine halt trouble that causes; Blast sampler porch often hangs carbon distribution also can make the pressure measurement error cause fault; Because of barrier film is the book elastomeric material, also can the sluggish malfunctioning phenomenon of action appear because of reason such as aging; Because of blast switch need be installed near the blower fan, shell body also can cause phenomenons such as barrier film storehouse sealing gas leakage because of temperature distortion, moves to complete machine and causes disorderly closedown; And blast switch can not keep in repair once break down; Can only whole replacing, often cause a lot of inconvenience to the user, especially winter heating season because of accessory is untimely; Often, suffer untold misery to the difficulty that the user causes because of waiting for accessory normally heating for days.
Summary of the invention
The utility model is and traditional diverse detection method of blower fan pressure tester that purpose is the shortcoming that overcomes prior art, provides a kind of simple in structure; Cost is low, and reliable in action is not influenced by environment for use; Long service life, the baffle-type blast switch of free of replacement.
The purpose of the utility model is realized by following technical proposals: a kind of baffle-type blast switch; It is characterized in that: it comprises bearing; On bearing, be hinged with the blast baffle plate; The gusset end of blast baffle plate is connected with pressure regulating screw, and pressure regulating screw matches with the playback pressure spring that on bearing, is provided with, the gusset end face contact matching of the touch panel of sensitive switch and blast baffle plate.
The utility model is obtained beneficial effect: the utility model is the baffle-type blast switch; During use, the blast baffle plate is directly inserted fan outlet from the blower fan sidepiece, blast directly blows the blast baffle plate; Make the blast baffle plate be upturned along pin joint by an end of blast effect; And the gusset end of blast baffle plate pushes the touch panel of sensitive switch downwards, makes sensitive switch open and wind pressure signal is exported, and the gusset end of blast baffle plate is connected with pressure regulating screw; Pressure regulating screw matches with the playback pressure spring that on bearing, is provided with, can be through the required control blast of pressure setting of adjustment spring.Have simple in structurely, cost is low, and reliable in action does not receive environment for use to influence advantages such as long service life, free of replacement.
Description of drawings
Fig. 1 is the baffle-type blast switch structural representation of the utility model.
Fig. 2 is the baffle-type blast switch and the blower fan syndeton sketch map of the utility model.
Among the figure: 1 sensitive switch, 2 touch panels, 3 pressure regulating screws, 4 playback pressure springs, 5 bearings, 6 blast baffle plates, 7 blower fans, 8 fan outlets.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1 and 2; The baffle-type blast switch of the utility model comprises bearing 5; On bearing 5, be hinged with blast baffle plate 6; The gusset end of blast baffle plate 6 is connected with pressure regulating screw 3, and pressure regulating screw 3 matches with the playback pressure spring 4 that on bearing 5, is provided with, the touch panel 2 of sensitive switch 1 and the gusset end face contact matching of blast baffle plate 6.During use: the bearing 5 of baffle-type blast switch is fixed on the sidewall of blower fan 7 air opening ends, and blast baffle plate 6 patches into blower fan air outlet 8 from blower fan 7 straight wall.
The embodiment of the utility model baffle-type blast switch is not limited to an above-mentioned embodiment, and all employing blast of pressure tester that use this area directly act on the scope that technical scheme that baffle plate carries out pressure measurement all belongs to the protection of the utility model claim.
