Abstract
The utility model provides an adjustable safety explosion-proof valve comprising a base, a sloping block, a roller, a fixed support, a tie bar, an adjusting nut, a spring, a limiting nut and a box iron support. The base is arranged on a door frame, the sloping block is arranged on the base, and the other components are arranged on an explosion-proof door. The fixed support which is used to clamp the roller is connected with the tie bar, the spring is sleeved on the tie bar, the compression amount of the spring is adjusted through the adjusting nut, the box iron support is welded onto the explosion-proof door in order to provide an axial guide function for the tie bar, and the tie bar is positioned through the limiting nut. When the pressure in a bag type collector exceeds an extreme value, the explosion-proof door can open automatically to release the pressure and the opening speed of the explosion-proof door is easy to be adjusted, thereby bringing about convenient and safe use without any damage to the components. The acting force of the sloping block on the roller enables the explosion-proof door to be pressed tightly onto the explosion-proof door frame, thereby bringing about better sealing performance and lower air leakage coefficient. The adjustable safety explosion-proof valve is easy to be assembled on a large-scale explosion dust collector with simple structure, easy manufacture, convenient assembly as well as low cost.
Description
Technical field
The utility model relates to the antiknock device of sack cleaner, particularly a kind of adjustable safety explosion-proof valve.
Background technique
Sack cleaner is inner to be provided with explosion-proof valve and requisite quench equipment not to other aspect expansions in order blast is confined to, particularly important.
Explosion-proof valve commonly used is concluded four kinds of explosion-proof diaphragm, heavy hammer type, latch-type and pin axle types.Heavy hammer type explosion-proof valve volume is big, consumptive material is many, air leakage coefficient is bigger, needs after the pressure release to readjust; Need integral replacing after the diaphragm type explosion-proof valve pops, install separately; Latch-type explosion-proof valve complex structure, to adjust difficulty big and involve great expense; The pin axle type explosion-proof valve can be cut off bearing pin when pressure release, continuing to use needs to change bearing pin.
Summary of the invention
In order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model provides a kind of adjustable safety explosion-proof valve, and it is simple in structure, easy processing, easy for installation, be convenient to be installed in large-scale explosion-proof deduster, and cost is low.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted, and comprises base, skewback, roller, fixing frame, pull bar, adjusting nut, spring, stop nut and channel-section steel support.Base is installed on the explosion-proof doorframe, and skewback places on the base, and remaining component is installed on the explosion proof door.Fixing frame is used for hold-down roll and be connected with pull bar, and spring housing is regulated its decrement on pull bar and by adjusting nut, and the channel-section steel support is welded on and is used on the explosion proof door coming positioning tie bar for pull bar provides axially directed function by stop nut.
When the deduster internal pressure surpassed setting numerical value, the air-flow strength percussion of coming Self-duster was in explosion proof door, and roller will move and cross skewback along the skewback on the base this moment, the while pressure spring, and explosion proof door is opened.After deduster pressure discharged, explosion proof door was because deadweight is closed voluntarily, and roller is crossed skewback by original route equally and turned back to the home position, finishes whole pressure releasing process.
Can change the amount of deformation of spring by adjusting nut, control the speed of opening explosion proof door.
The beneficial effects of the utility model are: when the sack cleaner internal pressure value of overstepping the extreme limit, can open the explosion proof door release pressure automatically, and adjust the speed that explosion proof door is opened easily, safety easy to use does not cause any damage to parts.The active force of skewback pair roller makes explosion proof door be pressed on the explosion-proof doorframe, and sealability is better, and air leakage coefficient reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that base, 2 is that skewback, 3 is that roller, 4 is that fixing frame, 5 is that pull bar, 6 is that adjusting nut, 7 is that spring, 8 is that stop nut, 9 is that explosion proof door, 10 is that channel-section steel support, 11 is explosion-proof doorframe among the figure.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, a kind of adjustable safety explosion-proof valve comprises base 1, skewback 2, roller 3, fixing frame 4, pull bar 5, adjusting nut 6, spring 7, stop nut 8, explosion proof door 9, channel-section steel support 10, explosion-proof doorframe 11.
When the deduster internal pressure surpass to be set numerical value, the air-flow strength percussion of coming Self-duster was in explosion proof door 9, and roller 3 will move and crosses skewback 2 along the skewback on the base 12 this moment, pressure spring 7 simultaneously, and explosion proof door 9 is opened.After deduster pressure discharged, explosion proof door 9 was because deadweight is closed voluntarily, and roller 3 is crossed skewback 2 by original route equally and turned back to the home position.
Can change the amount of deformation of spring 7 by adjusting nut 6, control the speed of opening explosion proof door 9.
When the sack cleaner internal pressure value of overstepping the extreme limit, the utility model can be opened explosion proof door 9 release pressures automatically, and adjusts the speed that explosion proof door 9 is opened easily, and safety easy to use does not cause any damage to parts.The active force of skewback 2 pair rollers 3 makes explosion proof door 9 be pressed on the explosion-proof doorframe 11, and sealability is better, and air leakage coefficient reduces.
