Abstract
The utility model relates to an it blows relief pressure valve of expecting exhaust -gas treatment to be exclusively used in bulk vehicle, including the valve body, the valve body is equipped with air inlet and gas outlet, and installs depressurization portion spare and retaining ring in the valve body, is equipped with a plurality of air vent on the depressurization portion spare, when being failure to actuate, leaves the clearance between depressurization portion spare and the retaining ring, and during the action, depressurization portion spare slides in the valve body to contacting with the retaining ring. The utility model discloses when being failure to actuate, the air current admits air from the clearance of air vent and valve plate / retaining ring, when in the bulk vehicle around the material headroom, useless large -minded, atmospheric pressure is high, when the air speed is fast, the valve plate is sliding in solid fixed valve pole under the back thrust of atmospheric pressure, when the valve plate contacted with the retaining ring, the air current can only be followed the air vent and admitted air, has lightened dust collector's pressure greatly, worked as the waste gas pressure decrease, the valve plate restores to the throne under the effect of spring. The utility model discloses simple structure, convenient to use, and pressure -relief is very good.
Description
Technical field
This utility model relates to a kind of air relief valve, especially relates to a kind of bulk vehicle that is exclusively used in and blows the air relief valve of material exhaust-gas treatment.
Background technology
Dry-mixed mortar is in architectural engineering application process, it is to move silo by being placed in the sealing in construction site, realizing temporarily the depositing of mortar, automatic watering stirring, the mortar in mobile silo is then used compressed air by special motar carrier vehicle, is sent in silo by air-blowing mode.For avoiding occurring dust pollution accident, general employing dust removal installation carries out dedusting.In existing dust arrester, in car before and after material headroom, exhausted air quantity is big, air pressure is high, air velocity is fast, affects the normal work of dust arrester, needs a kind of special air relief valve to solve this problem.This utility model thus produces.
Utility model content
Above-mentioned technical problem for prior art, the purpose of this utility model is to provide a kind of bulk vehicle that is exclusively used in and blows the air relief valve of material exhaust-gas treatment, it is effectively worked by valve plate, air inlet at dust arrester implements decompression, slow pressure, efficiently solving in bulk vehicle before and after material headroom, exhausted air quantity is big, air pressure is high, air velocity is fast and affects the normal work problem of dust arrester.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
A kind of bulk vehicle that is exclusively used in blows the air relief valve of material exhaust-gas treatment, including valve body, described valve body is provided with air inlet and gas outlet, and decompression member and back-up ring are installed in valve body, described decompression member is provided with several passages, when being failure to actuate, leaves gap between decompression member and back-up ring, during action, described decompression member slides in valve body and contacts with back-up ring.
Described decompression member includes the fixing valve rod being arranged on valve body, on described fixing valve rod, fixed block and slide block are installed, connect between described fixed block and slide block and have spring, on described slide block, valve plate is installed, described valve plate is positioned at the side of air inlet, described passage is positioned on valve plate, and during action, described valve plate slides on fixing valve rod and contacts with back-up ring.
Described valve body is L-type valve body.
The beneficial effects of the utility model are as follows:
This utility model is exclusively used in bulk vehicle and blows the air relief valve of material exhaust-gas treatment, when it is failure to actuate, air-flow air inlet from the gap of passage and valve plate/back-up ring, before and after material headroom in bulk vehicle, when exhausted air quantity is big, air pressure is high, air velocity is fast, valve plate slides under the back pressure of air pressure in fixing valve rod, when valve plate contacts with back-up ring, air-flow can only significantly reduce the pressure of dust arrester from passage air inlet, when exhaust gas pressure reduces, and valve plate resets under the action of the spring.This utility model simple in construction, easy to use, and effect of easing stress is the best.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model；
Fig. 2 is left view structural representation of the present utility model；
Wherein, 1 it is valve body, 2 is back-up ring, 3 is valve plate, 4 is spring, 5 is fixing valve rod, 6 is fixed block, 7 is slide block, 8 is passage, 9 is air inlet, 10 is gas outlet.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described, but protection domain of the present utility model is not limited to this.
As illustrated in fig. 1 and 2, this utility model is exclusively used in bulk vehicle and blows the air relief valve of material exhaust-gas treatment, including valve body 1, valve body 1 is L-type valve body, it is provided with air inlet 9 and gas outlet 10, and decompression member and back-up ring 2 are installed in valve body 1, decompression member includes the fixing valve rod 5 being arranged on valve body 1, on fixing valve rod 5, fixed block 6 and slide block 7 are installed, connect between fixed block 6 and slide block 7 and have back-moving spring 4, slide block 7 is provided with valve plate 3, and valve plate 3 is positioned at the side of air inlet 9, and valve plate 3 is provided with several passages 8.
When this utility model is failure to actuate, gap is left between valve plate 3 and back-up ring 2, air-flow air inlet from the gap of passage 8 and valve plate/back-up ring, before and after material headroom in bulk vehicle, when exhausted air quantity is big, air pressure is high, air velocity is fast, valve plate 3 slides under the back pressure of air pressure in fixing valve rod 5, when valve plate 3 contacts with back-up ring 2, air-flow can only significantly reduce the pressure of dust arrester from passage 8 air inlet, when exhaust gas pressure reduces, and valve plate 3 resets under the effect of spring 4.
This utility model simple in construction, easy to use, and effect of easing stress is the best.
Above-described embodiment is only used for illustrating inventive concept of the present utility model, rather than the restriction to this utility model rights protection, all changes utilizing this design that this utility model carries out unsubstantiality, protection domain of the present utility model all should be fallen into.
