Abstract
The invention relates to a baffle type wind-pressure switch. The baffle type wind-pressure switch is characterized by comprising a support, wherein a wind-pressure baffle is hinged on the support; an angle plate end of the wind-pressure baffle is connected with a pressure adjusting screw which is matched with a return pressure-adjusting spring arranged on the support; and a contact plate of a microswitch is in contact matching with the angle plate end surface of the wind-pressure baffle. When in installation, the wind-pressure baffle is directly inserted into an air outlet of a fan from the side part of the fan; the wind pressure blows the wind-pressure baffle directly, so that one end of the wind-pressure baffle, which is acted by the wind pressure, is upwarped along the hinged point, while the angle plate end of the wind-pressure baffle pushes and presses down the contact plate of the microswitch, and the microswitch is switched on and outputs a wind-pressure signal; the angle plate end of the wind-pressure baffle is connected with a pressure-adjusting screw; the pressure-adjusting screw is matched with the return pressure-adjusting spring arranged on the support; and the needed control wind pressure is set by adjusting the pressure of the spring. The baffle type wind-pressure switch has the advantages of simple structure, convenience in adjustment, low cost, stable and reliable action, long service life, no influence from the use environment, no need of replacement, and the like.
Description
Technical field
The invention 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 present invention is and traditional diverse detection method of blower fan pressure tester, and purpose is the shortcoming that overcomes prior art, provides a kind of simple in structure, and 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 objective of the invention is to realize: a kind of baffle-type blast switch by following technical proposals; 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 present invention obtains beneficial effect: the present invention 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 little merit switch opens and with wind pressure signal output, 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 a baffle-type blast switch structural representation of the present invention.
Fig. 2 is baffle-type blast switch of the present invention and blower fan syndeton sketch map.
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 present invention is described further.
With reference to Fig. 1 and 2; Baffle-type blast switch of the present invention 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 extreme face contact matching in angle 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 baffle-type blast switch of the present invention 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 claim protection of the present invention.
