The pressure equaliser that the utility model provides, preferably, described pressure relief unit includes base and at least one counterweight of fixedlying connected with described middle port, described base is provided with a plurality of release aperture that are communicated to described pressure balance chamber, on described base, be provided with pillar, described at least one counterweight is placed on the base movably by pillar, thereby can seal described a plurality of release aperture with set pressure.
Understand easily, the utility model is regulated the pressure size by dissimilar counterweights, realizes the pressure equilibrium in the trunk for expansion, and is therefore easy to operate and replaceability is strong, can be used for multiple different required pressure balance; Secondly, in the process of the test when pressure reaches balance pressure piping seal, pressurized air can not continue to emit, thereby has saved resource and reduced noise pollution; Once more, in process of the test because the pressure surge in the trunk for expansion that the intensification of liquid coolant can cause, pressure equaliser of the present utility model can pass through the in time outside release of movable counterweight with the pressure equilibrium in the assurance trunk for expansion, thus the technical quality of raising test; And the counterweight regulative mode of the utility model device can be changed rapidly, when changing the pressure of liquid coolant pressurization if desired in process of the test, just can finish fast by the increase and decrease counterweight, thereby improve engine subsystems testing laboratory work efficiency.
The beneficial effects of the utility model are that significantly it is workable, has improved test efficiency, and coolant pressure balance device of the present utility model can also be kept away the pressurized air wasting phenomenon.The utility model pressure equaliser compactness, easy to use.
[description of drawings]
Engage accompanying drawing below, preferred implementation of the present utility model is described in detail, wherein,
Fig. 1 is an engine coolant pressure equaliser synoptic diagram.
[embodiment]
Understand easily, according to the technical solution of the utility model, do not changing under the connotation of the present utility model, one of ordinary skill in the art can propose a plurality of frame mode of the present utility model.Therefore following embodiment and accompanying drawing only are to the specifying of the technical solution of the utility model, and should not be considered as of the present utility model all or be considered as qualification or restriction to technical solutions of the utility model.
As shown in Figure 1, pressure equaliser of the present utility model mainly includes housing 1 and pressure relief unit 2.Wherein, housing 1 is preferably square configuration, and housing 1 inside has pressure balance chamber.On three faces of described housing 1, have inlet 11, outlet 12 and middle port 13 respectively, wherein enter the mouth 11, outlet 12 and middle port 13 be connected with housing 1 pressure inside counter balance pocket respectively.Inlet 1 is connected with compressed air source.And preferably, 11 places are equipped with first bindiny mechanism 14 that can be connected with the tracheae of compressed air source at inlet, thereby make pressurized air 11 to enter into pressure balance chamber by entering the mouth.This first bindiny mechanism can for screw connection structure, certainly those skilled in the art is appreciated that also first bindiny mechanism 14 also can be the coupling arrangement of other modes, as long as guarantee inlet 11 and tracheae reliably be connected and seal.
Correspondingly, 12 places are equipped with second bindiny mechanism 15 that is connected with cooling liquid expansion tank in outlet, thereby make the pressurized air in the pressure balance chamber to enter into cooling liquid expansion tank by exporting 12.This bindiny mechanism can for screw connection structure, certainly those skilled in the art is appreciated that also second bindiny mechanism 15 also can be the coupling arrangement of other modes, is connected and seals as long as guarantee reliable between outlet 12 and the cooling liquid expansion tank.In an embodiment of the present utility model, inlet 11 is identical with the aperture of outlet 12, and is in respectively on two corresponding sides of housing.In further embodiment of the present utility model, first bindiny mechanism 14 is identical with the shape of second bindiny mechanism 15.
13 places are provided with pressure relief unit 2 in middle port, and described pressure relief unit 2 so is arranged on the middle port 13, make when the pressure in the counter balance pocket is within setting value, middle port 13 is sealed by pressure relief unit 2, when the pressure in the counter balance pocket exceeds setting value, described pressure relief unit 2 can be compressed the air slight jack-up that makes progress, thereby the pressure gas that middle port 13 can discharge in the counter balance pocket makes the pressure in counter balance pocket and the cooling liquid expansion tank be in steady state (SS).In an embodiment of the present utility model, pressure relief unit 2 includes base 21 and at least one counterweight 23 of fixedlying connected with middle port 13, described base 21 is provided with a plurality of release aperture (not shown), the pressure release that described release aperture is connected with middle port 13 and is used for counter balance pocket.Be provided with pillar 22 in the centre of described base 21, one or more counterweight 23 is placed on the base 21 movably by pillar 22.And counterweight closes described a plurality of release aperture with certain pressure when counterweight is placed on the pillar 22.When the pressure in the counter balance pocket was much, the pressurized air in the described release aperture can be with one or more counterweight jack-up, thus relief pressure.
Certainly, those skilled in the art will appreciate that pressure relief unit 2 can also be other structural design, as long as it can realize that the pressure in the counter balance pocket discharges to keep the pressure equilibrium in the counter balance pocket.
Pressure equaliser of the present utility model is in when pressurization, and pressurized air 11 enters into pressure balance chamber 2 by entering the mouth.At first according to adding pressure request, place corresponding counterweight in advance before this.Pressure gas in the pressure balance chamber 2 flow in the cooling liquid expansion tank by exporting 12, makes that the pressure in the liquid coolant reaches setting value.When causing system pressure greater than desired set pressure when system pressurization back or owing to the coolant temperature rising, pressure entrance 11 stops pressurization, this moment, the pressure in the stable cavity overcame counterweight weight, thus counterweight by excess pressure slightly upwards jack-up carry out release so that middle port 13 is communicated with environmental facies.When system pressure after the release reached set pressure once more, counterweight fell sealing middle port 13, and system reaches air-tight state again, makes system stability remain on required pressure.
The utility model device is simple, convenient, practical.Not only improved work efficiency, the warranty test quality, and effectively economize on resources.
