Description
Technical field
This utility model relates to relief valve, a kind of relief valve and the combination unit of rupture disk.
Background technology
Spring loaded safety valve is a kind of main product commonly used, and its operation principle is that the power utilizing spring carrys out control valve
The closing forces of the sealing surface of door, when the stress of valve sealing face controls power more than spring, valve automatically opens up, thus full dose row
Put；When valve sealing face power controls power less than spring, valve is automatically switched off, thus ensures equipment safety operation.
At present, existing rupture disk is directly mounted in relief valve, does not take any extra installation measure, leads
Cause rupture disk cannot normal mounting, before realizing self-acting, easily depart from installation place, thus cause relief valve to lose voluntarily
The effect of valve opening release.Existing relief valve lacks the Pressure gauge for valve inner pressure detecting, and Pressure gauge is more of arranged
On the process equipment such as boiler, pressure vessel, the internal pressure of equipment can only be detected thus, it is impossible to know valve inner pressure
Power is the most normal, even if rupture disk also cannot be known after explosion, causes the very first time to change rupture disk so that safety
Valve loses effect itself.Existing relief valve is after Open valve releases certain pressure, and valve closing has certain micro-leakage, leads
Cause gas leaks outside, and affects environment, the most also can increase production cost.
Utility model content
The shortcoming that this utility model to solve above-mentioned prior art, it is provided that a kind of relief valve rational in infrastructure, easy to use
Combination unit with rupture disk, it is possible to valve inner force value detected in time, and the pressure that can be more reflected on Pressure gauge
To rupture disk, whether explosion judges power, and can change in time, and this does not exist micro-leakage after valve opening and closing to make valve yet
Situation, convenient and swift.
This utility model solves the technical scheme that its technical problem uses: the combination unit of this relief valve and rupture disk,
Including valve body, valve seat, flap, valve rod, spring, valve gap, valve seat is installed on the entrance point of valve body, passes through valve between valve body and valve gap
Lobe connects, and forms sealing and coordinate between flap with valve body, valve gap, and valve rod mobile link is in valve gap, and the left and right two ends of valve rod are cased with
Spring base, spring is installed between two spring bases, and the spring base being wherein placed in valve rod right-hand member is fixed in valve gap, and valve rear end is even
Being connected to connecting tube, be provided with rupture disk clamper, be provided with rupture disk in rupture disk clamper in connecting tube, rupture disk is placed in quick-fried
At fragmentation clamper entrance point；Connecting tube rear end connects import adpting flange；The port of export of connecting tube is provided with for the company of sealing
The sealing lid of the adapter port of export, sealing lid is externally provided with and is connected in interior Disc holder by sealing lid, and the Disc holder back side is fixed with tailing axle,
Tailing axle mobile link is in flap, and tailing axle is threaded onto in the set screw of valve rod；The port of export of connecting tube is provided with and coordinates with sealing to cover
The sealing gasket used；Pressure gauge for detecting valve inner pressure is installed outside connecting tube.So, the master in valve rod is valve body
Element to be driven, valve rod coordinates spring to realize sealing the keying of lid, and seals lid and install to Disc holder with the form of clamping,
Disc holder makes medium active area increase, and job demand based on relief valve is to open suddenly under emergency case, coordinates and adjusts
Pitch circle, controls suitable blow pressure, it is also possible to reduce seal lid and Disc holder difficulty of processing when being formed in one and
Save processing cost, and be additionally provided with sealing gasket at the port of export of connecting tube, after limited can preventing valve closing thus
Produce the situation of micro-leakage.The setting of rupture disk clamper is not only convenient for rupture disk and installs, and rupture disk is from traditional non-reclosing
Formula is transformed into reclosable so that rupture disk without repeat change, rupture disk clamper by an easily removable assembling
Fixture, the rupture disk bilayer fire resistant apparatus re-assemblied will provide a guarantee, and fully seal, it is simple to the inspection of rupture disk
Look into and change.When rupture disk extremely leaks or ruptures, Pressure gauge can show the pressure of relief valve inlet side immediately, in order to work
Equipment is overhauled and changes rupture disk by personnel, it is ensured that relief valve normally uses.
The most perfect, sealing gasket is refractory seals pad.So, it is contemplated that relief valve is usually used in boiler, pressure vessel
With on pipeline, these process vessels are usually used in high temperature process, the situation of non-high-temperature resistant sealing gasket meeting generating material fusing, thus lead
Cause relief valve cannot normally use, therefore sealing gasket is refractory seals pad.
The most perfect, all it is bolted between valve body, connecting tube, import adpting flange.So, bolt is easily grasped
Make, and good connecting effect, also there is detachability, it is simple to the later stage maintenance to valve, save time and cost.
This utility model has the advantages that: of the present utility model rational in infrastructure, using effect good, the setting of sealing gasket makes
Obtain relief valve and the situation of micro-leakage will not occur again, reduce production cost, it is ensured that producing and be normally carried out, rupture disk utilizes rupture disk to press from both sides
Holder is fixed so that rupture disk, without departing from former setting position, plays the effect of oneself safety protection, the most manometric
Setting can be when rupture disk extremely leaks or ruptures, and Pressure gauge can show relief valve inlet side pressure immediately, points out overhaul of the equipments
Time should change rupture disk, very hommization, be worthy to be popularized.
