Description
Technical field
The present invention relates to a kind of core level gate valve, particularly a kind of core level gate valve with antivibration anti-vibration ability.
Background technique
As everyone knows, nuclear power has clean environment firendly, the feature such as profitable, is feasible, high efficient energy sources coal resources to alternative ability at present, also more and more payes attention to the development of nuclear power both at home and abroad.But the safety problem of nuclear power station is the problem that we extremely pay close attention to and pay attention to, the engineered safety system of nuclear power station comprises four aspects: accident cooling system, flood pattern, isolated system and emergency cooling system.In these systems and between system, all formed by many pipelines, the sealing and the stability that connect in order to ensure these pipelines, conventionally by valve as connection device.Especially three grades of gate valves of the core in emergency cooling system play a key effect to the Security of the whole decorum.
Nuclear power valve is different from common valve, should check according to nuclear power valve standard design.Nuclear power valve Standard General is according to two particular criteria, and one of them title is that the name of another standard of safe shutdown earthquake (SSE) is called operation according to earthquake (OBE).Wherein safe shutdown earthquake (SSE) is to the security implication maximum to nuclear power plant; Analyze valve anti-vibration, be exactly generally to analyze the valve stress that valve produces during to security of operation earthquake (SL1) in the situation that closing and open, and the valve stress that valve produces analyze safe shutdown earthquake (SL2) in the situation that opening time.If the structure of three grades of nuclear safety and nuclear safety secondary valve is not subject to stress rupture under envelope working condition, can determine the design stress evaluation criterion that meets valve.The antidetonation 1I class valve of nuclear safety II level and III level needs the structural stress that carries out respectively valve components under normal and accident conditions to check.In addition, also need to consider the effect of pipeline fluid for nuclear power station valve, analyze its stress response under fluid and earthquake loading effect, check its structural integrity.Therefore as core level gate valve possess good antidetonation, shock-absorbing ability is very important.
Summary of the invention
The object of the invention is to, a kind of core level gate valve is provided.The present invention has good vibration damping, anti-vibration performance, also has good Security and reliability, thereby increases the service life.
Technological scheme of the present invention: a kind of core level gate valve, it is characterized in that: comprise valve body, in valve body, be provided with flashboard, flashboard is provided with the valve rod extending to outside valve body, valve body is provided with the valve gap that is positioned at flashboard top, and valve gap is provided with the support being enclosed within on valve rod, and valve rod top is provided with handle, valve body both sides are provided with antivibration ring, between antivibration ring and valve body, are provided with rubber ring.
In aforesaid core level gate valve, described flashboard is provided with seal ring around, ensures sealing when flashboard cuts out.
In aforesaid core level gate valve, described stent side portion is evenly provided with four stiffening ribs, thereby improves intensity and the anti-vibration performance of support.
In aforesaid core level gate valve, described valve gap is connected through attachment hole with valve body.
In aforesaid core level gate valve, described antivibration ring comprises the elastic ring body of disconnection, and elastic ring body two ends are provided with connecting sheet, and the lower end of connecting sheet is provided with for fixing installation foot, and two connecting sheet via through holes connections are fixedly clamped rubber ring.
In aforesaid core level gate valve, described rubber ring is thick is 5-10mm, and wide is 10-30mm.
Compared with prior art; the present invention by having increased antivibration ring on valve body; adopt rubber ring to cushion as mesosphere simultaneously; for fully absorbing the vibration of external disturbance to valve body, thereby protection gate valve has good vibration damping, anti-vibration performance; also there is good Security and reliability; thereby increase the service life, reduce frequency of maintenance, reduce replacement cost.And the present invention has also increased by four stiffening ribs for improving intensity and the anti-vibration performance of support.The present invention adopts attachment hole to be connected with valve body, valve gap support valve gap, and seal ring is also installed around flashboard, makes it have good seal performance.The present invention also adopts the rubber ring of specific thicknesses, can make the valve body amplitude under same frequency reduce half, thereby significantly improves vibration damping, anti-vibration effect.By frequency response analysis, more than known employing the present invention can reduce the Oscillation Amplitude 15dB of core level gate valve under low-frequency vibration, greatly reduce the impact of external vibration on valve.
