Description
Technical field
The utility model relates to a kind of core level butterfly valve, particularly a kind of core level butterfly valve with antivibration ring.
Background technique
Dish valve is a kind of important mechanical device, for nuclear power plant's pipeline.By the adjusting to valve opening, the flow of pipeline and pressure are changed.According to real data, one has 30,000 deck valve doors for certain nuclear power station with two 1,000,000 KW units.Although the cost of investment of valve only accounts for 2% of nuclear power station, exceed 50% of total maintenance expenses for the valve maintenance cost of a year.
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 safe shutdown earthquake (SSE); The name of another standard is called operation according to earthquake (OBE).The wherein security implication maximum of safe shutdown earthquake (SSE) 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.And current butterfly valve does not all have antihunt action, thereby affect working life.
Model utility content
The purpose of this utility model is, a kind of core level butterfly valve with antivibration ring is provided.The utlity model has good vibration damping, anti-vibration performance, manual and electric is opened and is controlled simultaneously, and the feature of convenient operation, also has favorable sealing property, and the advantage of long service life has good safety and reliability.
The technical solution of the utility model: there is the core level butterfly valve of antivibration ring, it is characterized in that: comprise valve body, be provided with dish plate in valve body, on dish plate, be connected with the valve rod extending to outside valve body, valve rod is connected with handle through worm speed reducer, and worm speed reducer is fixed through support, and valve body both sides are provided with antidetonation ring.
In the aforesaid core level butterfly valve with antivibration ring, on described worm speed reducer, be also connected with the actuating motor for motorized motions dish plate.
In the aforesaid core level butterfly valve with antivibration ring, described valve rod and dish plate are to be rigidly connected.
In the aforesaid core level butterfly valve with antivibration ring, described dish plate outer ring is provided with seal ring.
In the aforesaid core level butterfly valve with antivibration ring, described stem lower portion is provided with the thrust pad being fixed on valve body.
In the aforesaid core level butterfly valve with antivibration ring, described thrust pad below is provided with the blind flange for withstanding thrust pad, and blind flange is fixed on valve body through bolt, packing ring.
In the aforesaid core level butterfly valve with antivibration ring, described valve rod top sidepiece is provided with filler, and filler is provided with hold-down grid.
In the aforesaid core level butterfly valve with antivibration ring, between described antidetonation ring and valve body, be provided with rubber ring.
Compared with prior art, the utility model is by increased antivibration ring on valve body, and for fully absorbing the vibration of external disturbance to valve body, thereby protection butterfly valve ensures working life; And the utility model also has manual drives and automatically drives the function of simultaneously controlling, and has greatly improved efficiency and the controllability of the opening and closing of valve.The utlity model has good vibration damping, anti-vibration performance, manual and electric is opened and is controlled simultaneously, and the feature of convenient operation, also has favorable sealing property, and the advantage of long service life has good safety and reliability.
