Abstract
The utility model provides an air-actuated spring blowout valve. The valve body of the blowout valve is fixedly connected with a back arm, the back arm is rotating connected with a valve board, and a seal subsidiary is arranged between the valve board and the valve body; an automatic reclosing mechanism controlled by the cylinder is connected with the valve body relative to the back arm, an air supply duct is provided on the cylinder to communicate with the valve intracavity. The blowout valve is turned on automatically to decompression when the pipe network system is in excessive pressure condition or the exploding accident happens, and the valve is turned off automatically after decompression, and thereby the continuous system air release is prevented and the pollution to the external environment is reduced, missionaries' personal safety near the system is protected. The blowout valve is safer to use and has the advantages of environment protection, simple structure and convenient maintenance, in addition, this valve is more widely used and the blasting compression is more accurate via choosing spring with different elastic force .
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of pneumatic elastic press type explosion-released valve.
Background technique
That explosion-released valve is widely used in is inflammable, explosive, in the toxic gas pipe network system, to open in system overpressure out-of-limit moment, play the effect of pressure release.At present, the explosion-released valve that circulates on the market is made up of valve body, clamp holder and rupture disk, and rupture disk is contained between valve body and the clamp holder.When system overpressure or when blasting accident, rupture disk can break moment, and intrasystem pressurized gas are discharged rapidly, with the pressure in the mitigation system, guarantees the safety of system.The explosion-released valve of said structure, when rupture disk broke pressure release, intrasystem inflammable, explosive or toxic gas can constantly leak from the rupture disk that breaks, thereby causes the unnecessary pollution of external environment condition, crisis periphery staff's safety.This explosion-released valve will cut off intrasystem toxic gas earlier when maintenance, toxic gas residual in the system is purged clean with nitrogen again, after treating that site environment reaches safety standard, the staff just can enter the on-the-spot rupture disk of changing on the explosion-released valve, to recover the proper functioning of pipe network system.So just cause its engineering time long, difficulty is big.And the rupture disk of this explosion-released valve exists difference at aspects such as material, thickness, thereby causes this type of explosion-released valve to have the inaccurate shortcoming of bursting pressure.
The model utility content
The purpose of this utility model just provide a kind of pollution little, the maintenance the easy and pneumatic accurately elastic press type explosion-released valve of bursting pressure.
The utility model is achieved in that affixed arm rest on valve body, and the valve plate that is rotationally connected on arm rest is provided with sealing pair between valve plate and the valve body; Side at the relative arm rest of valve body is connected with the automatic on-off mechanism of being opened by cylinder control, is connected to gas source conduit connecting valve intracoelomic cavity on cylinder.Like this, the compressed gas of pipe network system just can enter cylinder by gas source conduit.In pipe network system superpressure out-of-limit moment, the cylinder piston action, control automatic on-off mechanism opens automatically, valve plate be subjected to leak in the pipe network system pressurized gas impact and start voluntarily, pressurized gas can release from the valve seat of valve body.Valve plate is starting back and arm rest top bump, and bounce-back and returning relies on rebounding force and the gravity of self falling, by automatic on-off mechanism automatic blocking, valve plate is locked on the valve seat of valve body, thereby pipe network system is sealed once more, intrasystem gas is no longer leaked, and system works on.
Automatic on-off of the present utility model mechanism is at body wall connection activity clamp, but the upper end of clamp is the clamping valve plate, makes it the inclined-plane hook formation with valve seal, the outside, the lower end apical grafting cylinder piston rod of clamp, inboard apical grafting spring.When the gas that enters cylinder by gas source conduit reaches setting value, can promote the lower end that piston makes it to promote clamp, the stressed rotation of clamp, the inclined-plane hook formation of its upper end unclamps valve plate, makes it to open.After the pressure release, operating position can successfully be got back to by the inclined-plane of touching clamp upper end in the valve plate edge of resilience.Simultaneously, the spring of the inboard apical grafting in clamp lower end promotes clamp, makes the hook formation chucking valve plate of clamp upper end, the auto lock closure after the pressure release of realization explosion-released valve.
The utility model can be opened pressure release automatically in the pipe network system superpressure or when blasting accident, can be closed voluntarily after pressure release, in the anti-locking system gas continue leak, reduced pollution to external environment condition, protected peripheral staff's personal safety.The utility model uses safer, more environmental protection, and is simple in structure, is convenient to maintenance, and can select the spring of different elastic force as required, has wide range of applications, and bursting pressure is accurate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at the I place of Fig. 1.
Embodiment
As shown in Figure 1, at the affixed arm rest 2 of the sidewall of valve body 1, the upper end of arm rest 2 exceeds valve body 1, and its end, upper end tilts to the valve body direction.On arm rest 2,, be connected with the block rubber 4 that to touch mutually with arm rest 2 tops at the valve plate end face by bearing pin 6 valve plate 3 that is rotationally connected.When valve plate 3 upwards rotate dashed after, block rubber 4 can contact with the inclination position, top of arm rest 2.Like this, under the buffering of the affixed thereon block rubber 4 of the valve plate 3 of upspringing under the impact of pressurized gas, the infringement that has not only alleviated valve plate 3 and arm rest 2 bumps effectively and caused to explosion-released valve, and increased the spring-back force of valve plate 3, make valve plate 3 can more successfully realize closure.
Be provided with sealing pair between valve plate 3 and valve body 1, as shown in Figure 2, sealing pair adopts following structure: the sealing surface of seat of valve body is interior inclined-plane, and the sealing surface of valve plate 3 is the sloping platform face, and the table top middle part is embedded with seal ring 5, to improve its sealing.
Side at valve body 1 relative arm rest 2 is connected with the automatic on-off mechanism of being opened by cylinder 11 controls, this mechanism is the middle part of passing through bearing pin 8 connection activity clamps 7 at valve body 1 with respect to a side of arm rest 2, but the upper end of clamp 7 is clamping valve plate 3, make it the inclined-plane hook formation with valve body 1 sealing, the outside, the lower end apical grafting cylinder piston rod 10 of clamp 7, its inboard apical grafting spring 9.Spring 9 can be single or cluster spring.On cylinder 11, be connected to gas source conduit 12 connecting valve intracoelomic cavities.
