Abstract
The utility model discloses a kind of adjustable air relief valve of maximum stream flow, the passage passed through including a supplied gas, the annular groove with channel connection it is provided with on passage medial wall, one is laid for the valve block of blocking channel in this annular groove, be provided with in described passage one for increasing valve block blocking channel time resistance elastic mechanism, elastic mechanism one end is connected with passage medial wall, and the other end extends at annular groove.The resistance when this utility model using said structure increases valve block blocking channel by arranging elastic mechanism in passage, maximum safe traffic of the present utility model is promoted, meet when multiple stove uses simultaneously max-flow quantitative limitation, simultaneously, by regulating the design parameter of elastic mechanism, change elastic mechanism, to drag size during valve block blocking channel, realizes changing the purpose of maximum safe traffic.Visible, this utility model simple in construction, it is applicable to multiple stove and uses simultaneously.
Description
Technical field
This utility model relates to a kind of adjustable air relief valve of maximum stream flow.
Background technology
Air relief valve typically can arrange safety device, when valve inner flow exceedes setting value, plays the purpose blocking passage, it is to avoid security incident occur.Safety device in existing air relief valve is typically by arranging a valve block in passage, when flow exceedes setting value, by the combustion gas of flowing, valve block is promoted and blocking channel, restriction due to this structure, the safety device of existing air relief valve typically can only meet a stove and use, when more than three stoves of needs sharing an air relief valve, can only select and not have fool proof air relief valve, there is the most again certain security risk, because not having air relief valve with safety device can not automatically cut off when flow is excessive.A kind of adjustable air relief valve of maximum stream flow being applicable to multiple stage stove is provided for this this utility model.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of adjustable air relief valve of maximum stream flow.
This utility model solves its technical problem and be the technical scheme is that
A kind of adjustable air relief valve of maximum stream flow, the passage passed through including a supplied gas, the annular groove with channel connection it is provided with on passage medial wall, one is laid for the valve block of blocking channel in this annular groove, be provided with in described passage one for increasing valve block blocking channel time resistance elastic mechanism, elastic mechanism one end is connected with passage medial wall, and the other end extends at annular groove.
Described elastic mechanism is set to a spring, and described passage is provided with an installation groove ringwise, and this installation groove is connected with annular groove, and one end of described spring is positioned at this installation groove.
Described installation groove and annular groove junction are provided with arc angling.
Described installation groove and annular groove junction use elastomeric material to make.
Described channel cross-section is rounded, and described valve block is spherical in shape, and the diameter of valve block is more than the diameter of channel cross-section.
The beneficial effects of the utility model are: resistance when using this utility model of said structure to increase valve block blocking channel by arranging elastic mechanism in passage, maximum safe traffic of the present utility model is promoted, meet when multiple stove uses simultaneously max-flow quantitative limitation, simultaneously, by regulating the design parameter of elastic mechanism, change elastic mechanism, to drag size during valve block blocking channel, realizes changing the purpose of maximum safe traffic.Visible, this utility model simple in construction, it is applicable to multiple stove and uses simultaneously.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is generalized section of the present utility model.
Detailed description of the invention
With reference to Fig. 1, this utility model is a kind of adjustable air relief valve of maximum stream flow, the passage 1 passed through including a supplied gas, the annular groove 2 connected with passage 1 it is provided with on passage 1 medial wall, one is laid for the valve block 3 of blocking channel 1 in this annular groove 2, be provided with in passage 1 one for increasing valve block 3 blocking channel 1 time resistance elastic mechanism, elastic mechanism one end is connected with passage 1 medial wall, and the other end extends at annular groove 2.When having gas to flow in passage 1, can move by band movable valve block 3, when gas flow exceedes setting value, valve block 3 moves in passage 1, and extrudes elastic mechanism, to the completely plugged passage of valve block 31, now, the effect cut off by passage 1 after flow exceedes setting value can be played, prevent fortuitous event from occurring.Resistance when this utility model increases valve block 3 blocking channel 1 by arranging elastic mechanism in passage 1, maximum safe traffic of the present utility model is promoted, meet when multiple stove uses simultaneously max-flow quantitative limitation, simultaneously, by regulating the design parameter of elastic mechanism, change elastic mechanism, to drag size during valve block 3 blocking channel 1, realizes changing the purpose of maximum safe traffic.Visible, this utility model simple in construction, it is applicable to multiple stove and uses simultaneously.Additionally, position about annular groove 2 and elastic mechanism is arranged, it i.e. may be provided at the air inlet 4 of passage 1, also may be provided at the gas outlet 5 of passage 1, all can stably use, in the present embodiment, annular groove 2 and elastic mechanism are positioned at the gas outlet of passage 1, and the movable end of elastic mechanism is towards at air inlet.
As it is shown in figure 1, in the present embodiment, elastic mechanism is preferably arranged to a spring 6, and passage 1 is provided with an installation groove 7 ringwise, and this installation groove 7 is connected with annular groove 2, and one end of spring 6 is positioned at this installation groove 7；Spring 6 simple in construction, occupies little space, and service life is long, easy to adjust, but elastic mechanism is not limited to the structure of spring 6, and it also can use other embodiment, for example with having the pillar that resilient material makes, being fixed pillar one end, the other end is for the embodiment of valve block 3 extruding.Installing groove 7 and annular groove 2 junction is provided with arc angling 8, be provided with beneficially valve block 3 and the sealing of passage 1, installation groove 7 and annular groove 2 junction of arc angling 8 use elastomeric material to make, and elastomeric material is beneficial to the sealing of valve block 3 and passage 1；Passage 1 circular in cross-section, valve block 3 is spherical in shape, and the diameter of valve block 3 is more than the diameter in passage 1 cross section；Valve block 3 stable motion for valve block 3 spherical in shape provides safeguard, and the medial wall of passage 1 will not be produced abrasion simultaneously, and advantage is obvious.
Above-described embodiment is preferred version of the present utility model, and this utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the scope set by the application claim.
