Abstract
The invention belongs to a valve, and particularly relates to a quick pressure relief stop valve of a pressure stabilizer. The quick pressure relief stop valve of the pressure stabilizer is characterized by comprising a valve body and a valve cover, wherein the valve cover is arranged above the valve body; a bracket is arranged on the valve cover; a pressing plate communicating with the valve body is arranged on the bracket; an anti-rotation plate is further arranged on the valve cover; a switching disk is arranged on the valve cover; the valve cover is connected with an electric fitting through the switching disk; and a position indicator is further arranged on the bracket. The quick pressure relief stop valve has the following advantages: the structure is simplified to the maximum extent, so that the overall structure is compact, connection between components is reduced, the weight is effectively reduced, and the overall shock absorption performance is improved. Meanwhile, the quick pressure relief stop valve is simple in structure, and the possibility of failure is reduced.
Description
Technical field
The invention belongs to valve, more particularly to manostat fast pressure relief stop valve.
Background technology
For some special applications, such as in nuclear power plant, in order to prevent under major accident operating mode
Generation high-voltage fuse heap, need to arrange the fast decompression valve of two row redundancies, in major accident operating mode on manostat
It is lower to perform discharge pressure relief, at master control room or long-range shutdown station by operator according to relevant major accident
The manually opened valve of code is processed, the fast pressure relief of reactor coolant loop is completed.
In prior art, there is larger difficulty in the valve in design, selection and the performance evaluation in later stage,
Requirement to valve manufacture manufacturer is higher, therefore the manufacture of the valve can not be popularized.
The content of the invention
The present invention seeks to the defect for being directed to prior art provides a kind of manostat fast pressure relief stop valve.
The present invention for achieving the above object, is adopted the following technical scheme that:A kind of manostat fast pressure relief cut-off
Valve, it is characterised in that:Including valve body and valve gap, valve gap is arranged on valve body top, arranges on valve gap and props up
Frame, arranges the pressing plate connected with valve body on support, while torsional stop is also set up on valve gap, in valve gap
Upper setting transfer panel, valve gap is connected by the flange with Denso, and position indicator is also set up on support.
A kind of manostat fast pressure relief stop valve as above, wherein, horizontal " T " is provided with valve body
Font cavity, horizontal " T " the font cavity runs through the upper and lower ends of valve body, and horizontal cavity is extended to
Outside valve body, flap is set in the cavity, valve rod is set on flap, valve rod is passed through and is arranged on valve body
The valve gap of top.
The invention has the advantages that:Structure is simplified to greatest extent, compact overall structure is made, and is subtracted
Lack the connection between part, significantly reduced weight, improve overall anti-seismic performance.Meanwhile,
Simple structure, the probability of failure is reduced.
Description of the drawings

Fig. 2 relief valve internal structure schematic diagrams.
In figure:1. valve body, 2. valve gap, 3. support, 4. pressing plate, 5. torsional stop, 6. transfer panel, 7. Denso,
8. position indicator, 9. flap, 10. valve rod.
Specific embodiment
As shown in accompanying drawing 1~2, a kind of manostat fast pressure relief stop valve, including:Valve body 1 and valve gap 2,
Valve gap 2 is arranged on the top of valve body 1, and support 3 is arranged on valve gap 2, arranges and valve body 1 on support 3
The pressing plate 4 of connection, while also setting up torsional stop 5 on valve gap 2, arranges transfer panel 6 on valve gap 2,
Valve gap 2 is connected by the flange 6 with Denso 7, and position indicator 8 is also set up on support 3.
Horizontal " T " font cavity is provided with valve body 1, horizontal " T " the font cavity runs through valve
The upper and lower ends of body 1, horizontal cavity is extended to outside valve body 1, and flap 9 is arranged in the cavity,
Valve rod 10 is set on flap 9, and valve rod 10 is through the valve gap 2 for being arranged on the top of valve body 1.
The construction featuress of the valve include:Using the angie type structure of high in and low out, be conducive to the sealing of valve seat.
That has opened four pressure relief grooves on flap is cylindrical to meet lumen unloads pressure request, is conducive to the just normally opened of valve
Open.Valve clack cover fixes valve clack cover after assembling by being threaded into flap with spot welding, and this structure can bear larger
Axial force, it is simple and convenient as long as polishing off spot welding position when needing renewal part.Valve body, valve
Lid, support is adopted integral structure, i.e., is connected using 12 bolts.Support adopts cylinder type, carries
The overall anti-seismic performance of valve is risen.
Lumen pad adopts the graphite sealing gasket of inside and outside ring structure, with good sealing property.Simultaneously
Middle flange arranges lip welding structure, as backup seal, can effectively ensure that the pressure boundary of valve is complete.
Packing seal structure encloses each circle folder stainless steel silk flexibility stone in flexible graphite packing+two ends by middle four
Black filler.Simultaneously mobile load filling-material structure is employed, butterfly spring serves the effect of a dynamic compensation.It is spacing
Set can effectively prevent disc spring overvoltage from causing failure.
Position indicator is connected with support by support plate, and valve event is mutual with position indicator by torsional stop
It is dynamic.Torsional stop passes through key anti-rotation with valve rod, then is fastened with bolt.The structure design has taken into account torsional stop
The contact function of anti-rotating function and limit switch, reduces valve partses quantity, optimizes valve mechanism.
