Description
Technical field
The present invention relates to concrete mixing plant silos to protect accessory technical field, in particular to a kind of alarm pressure safety
Valve.
Background technique
The over-pressure safety device of existing concrete mixing plant silo generallys use mechanical compression safety valve, as shown in Figure 1,
It is made of valve body, pedestal, upper cover, sealing plate, spring, gasket, adjusting nut, screw rod etc., the height H of spring can be by turning
The adjustment adjusting nut above screw rod is moved to adjust, the unlatching that can correct safety valve as needed using this structure is (whole
It is fixed) pressure.The Product Level is mounted at the top of silo, and preparatory aperture at the top of silo, safety valve base is welded at the top of silo, makes
It is connected to inside silo with safety valve inside, forms confined space.When silo internal pressure be greater than external pressure (environmental pressure), it is interior
When external pressure difference is equal to or more than pressure setting parameter value, due to gas pressure, spring is compressed, and H numerical value becomes smaller, sealing plate
It is lifted up, gasket is detached from valve body sealing surface and forms exhaust clearance, and air-flow discharges, and reduces air pressure inside, reaches pressure release
Purpose, as shown in Fig. 2, by certain time, when external and internal pressure difference is less than pressure setting parameter value, due to the elastic force of spring
And the gravity of sealing plate, sealing plate move downward compression gasket, close valve, stop pressure release, complete a job and follow
Ring.
And pressure safety valve used in existing concrete mixing plant silo has the disadvantage that in bulk cement carrier toward cylinder
In storehouse when dnockout (pneumatic transmission), discharge pressure is 2~3Kg/c ㎡, and pressure in silo is caused slowly to rise.When silo internal pressure reaches
When to safety valve setting pressure, safety valve can directly open carry out pressure release, cannot accomplish to give warning in advance, and keep dusty gas direct
It is discharged into atmosphere, pollutes environment, only can just find alert when staff's discovery has dusty gas to be discharged into atmosphere
And stopping dnockout, discovery is later, may be such that more dusty gas can be discharged into atmosphere, and such as discovery will continue to not in time
The dnockout in silo, then the dusty gas being discharged into atmosphere is more, and environmental pollution is bigger, and in addition safety valve itself only has one
Layer protection, such as since cause specific causes safe defective valve, hypertonia can cause the safety accident of silo explosion in storehouse.

To uniform pressure.
Preferably, the outside of the spring 123 is equipped with elastic corrugated sheath 124, plays protection to spring 123 and makees
With.
Preferably, it is pressed with annular concentric ripple on the flexible sheet 116, it can be by import 316L stainless steel, HC/HB
(Hastelloy), Ta (tantalum), Ti (titanium), monel metal are made, and measuring cell can produce with pressure applied at just when pressure
The deformation of ratio.
Preferably, the spring 123 is all made of spring steel material and is made, and is heat-treated, zinc-plated on surface again later,
Elastic force is big, and anti-fatigue performance is good.
Preferably, the gasket 117 is made of silica gel material, and thermal stability is good, and chemical property is stablized, and is had higher
Mechanical strength, good seal performance.
Bulk cement carrier dnockout (pneumatic transmission) in silo, discharge pressure are 2~3Kg/c ㎡, and pressure in storehouse is caused constantly to rise,
As shown in figure 8, flexible sheet 116, which is pressurized, occurs flexible deformation, gradually support 108 is driven to move up.When external and internal pressure difference
When equal to alarm setting parameter value, support 108 pushes elastic slice 114 to move up, and elastic slice 113 depresses the switch of microswitch 109,
The NO of microswitch 109 is connected with the contact COM, alarm signal is exported to external controller by signal wire 110, to work people
Member's alarm, and stop the dnockout in silo.Alarm pressure is arranged parameter value and is lower than valve pressure release parameter value, and safety valve is not at this time
It opens, dusty gas will not be discharged into atmosphere, will not be polluted.Support 108, elastic slice 113 and 112 three of adjustment seat are formed
One Ge Gan thick stick mechanism can adjust the height h1 of adjustment seat 112 by adjusting screw 111, make the right end of elastic slice 113 with it is close
Height H2 numerical value between sealing plate 107 changes, and when work causes the lifting height h2 numerical value of the left end of elastic slice 113 that phase occurs
It should change, can reach the big minor adjustment purpose of alarm pressure, H2 numerical value is bigger, and alarm pressure is bigger.To prevent dusty gas from discharging
It pollutes, it is generally the case that alarm pressure setting value is 1000Pa smaller than vent pressure setting value.When pressure drops in silo
Certain numerical value, flexible sheet 116, which is pressurized, to be reduced, and is sprung back, is driven support 108 and elastic slice 113 to move down, make microswitch
109 contact NO and COM disconnects, and alarm signal releases, and can continue the dnockout in silo at this time.If staff does not adopt after alarm
Corresponding measure is taken, the dnockout in silo is continued to, pressure then will continue to rise in storehouse, as shown in figure 9, when pressure reaches valve
When setting pressure release parameter value, due to gas pressure, spring 123 can be compressed, and be lifted up sealing plate 107, and gasket 117 is de-
Sealing surface from valve body 102 forms exhaust clearance, carries out discouraged, avoids silo internal pressure excessive and explodes.By rotating spiral shell
Adjusting nut 121 on bar 119 can adjust the height H1 of spring 123, and the pressure for making spring 123 be applied to sealing plate 107 occurs
Variation, can reach the adjusting purpose of vent pressure size, H1 numerical value is smaller, and vent pressure is bigger.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
