In order to prevent that the hedging personnel from bringing harmful gas into the urgent danger prevention facility, air curtain device should start in the moment of opening urgent danger prevention facility sealed door, deadened extraneous harmful gas; When sealed door was closed, air curtain device was closed.Current on the market pneumatic valve product is more, but flow is generally all less, can not satisfy the traffic requirement of urgent danger prevention system chamber air curtain device.
The model utility content
In view of this, the purpose of this utility model provides a kind of air curtain interlock air valve, has satisfied the requirement of the air curtain interlock of urgent danger prevention system and the large flow of air curtain, guarantees the hedging personal security.
The purpose of this utility model is achieved through the following technical solutions:
Air curtain interlock air valve comprises linkage rod, has valve body, the adjustable lever that there is gas-entered passageway inside of valve pocket and be installed on the valve body and lead to the steam outlet pipe of valve pocket; Linkage rod and adjustable lever stretch in the valve pocket from the two ends of valve body respectively, and linkage rod is corresponding with the gas-entered passageway of adjustable lever, and Returnning spring is installed between linkage rod and the adjustable lever.
Further, the centerline of the center line of described linkage rod and adjustable lever is on the same level line; There are round boss rank the end of linkage rod, and this round boss component level is in valve pocket; The diameter of the rounded face of first order step is less than the diameter of gas-entered passageway, and the rounded face diameter of second level step is greater than the diameter of gas-entered passageway.
Further, described linkage rod and valve body contact position are equipped with seal ring, on the first order step on round boss rank seal ring are installed.
Further, described adjustable lever and valve body contact position are equipped with seal ring.
Further, on the described adjustable lever nut is installed, adjustable lever is connected with valve body by nut.
Further, hemispherical dome structure is adopted in the end of described linkage rod, and this end is positioned at outside the valve body.
Further, described steam outlet pipe adopts the heavy caliber output channel, and the steam outlet pipe internal diameter reaches 12mm.
The beneficial effects of the utility model are:
1. rational in infrastructure, the good seal performance of the utility model, large, the long service life of output flow, and adopt the adjustable valve door, output flow is adjustable, and the pneumatic control components of reliable high-quality is provided for the air curtain device of colliery urgent danger prevention system.
2. the air curtain interlock air valve that provides of the utility model is used with sealed door and air curtain, and when mine disaster occured, air curtain device was realized opening and closing interlock with sealed door, assurance hedging personal security by air curtain interlock air valve.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by following specification.
Description of drawings
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is air curtain interlock Principles of Air Valves figure of the present utility model.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in drawings, the utility model comprises successively: the adjustable lever 5 that there is gas-entered passageway linkage rod 1, the valve body 3 with valve pocket 10, inside and be installed on the valve body 3 and lead to the steam outlet pipe 9 of valve pocket 10.Linkage rod 1 and adjustable lever 5 stretch in the valve pocket 10 from the two ends of valve body 3 respectively, in adjustable lever 5 and valve body 3 contact position seal ring 4 are installed, and linkage rod 1 is equipped with seal ring 2 with valve body 3 contact position, and Returnning spring 6 is installed between linkage rod 1 and the adjustable lever 5.The centerline of the center line of linkage rod 1 and adjustable lever 5 is on the same level line, and there are round boss rank 11 end of linkage rod 1, and these round boss rank 11 are positioned at valve pocket 10; The diameter of the rounded face of first order step is less than the gas-entered passageway diameter, and the rounded face diameter of second level step is greater than the gas-entered passageway diameter.On the first order step on boss rank seal ring 7 is installed, the external diameter of sealing circle and the equal diameters of gas-entered passageway.Adjustable lever 5 outside being positioned at valve body 3 is equipped with nut 8, and adjustable lever 5 is connected with valve body 3 by nut 8.Nut 8 is used for secured adjusted bar 5, and adjustable lever 5 is used for the aperture of regulating valve.Unclamp nut 8, clockwise turn adjustable lever 5, valve opening reduces, on the contrary valve opening increases, and after mixing up, fastening nut 8 again.
Install air curtain interlock air valve on the sealed door, adjustable lever 5 connects source of the gas, and steam outlet pipe 9 connects air curtain device.Open source of the gas, close sealed door, the thrust of impelling linkage rod 1 to force to overcome air pressure and Returnning spring 6 is moved to adjustable lever 5 directions, when the seal ring 7 on the linkage rod 1 enters into the endoporus of adjustable lever 5 fully, and valve closing, air curtain device is without flow.Open sealed door, under the reposition force effect of Returnning spring 6, linkage rod 1 resilience playback, gas flow is transported to air curtain device by steam outlet pipe, forms the invisible valve curtain of one side, and the blocking-up ambient atmos enters the urgent danger prevention facility.
In order to ensure sealed door and air curtain device open and close flexibly, hemispherical dome structure is adopted in the described linkage rod of present embodiment 1 end, this end is positioned at outside the valve body 3.
In order to satisfy the large traffic demand of air curtain, the described steam outlet pipe 9 of present embodiment adopts the heavy caliber output channel, and the internal diameter of steam outlet pipe can reach 12mm.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
