Abstract
The utility model relates to a nuclear power diaphragm valve, which mainly consists of a valve body, a bonnet, a valve stem, a diaphragm, diaphragm nuts, a valve clack and an electrical device. The bonnet is arranged on the valve body connected with the diaphragm, one end of the valve stem is connected with the diaphragm through the diaphragm nuts while the other end of the valve stem is connected with the electrical device, and the valve clack is connected with the valve stem. Compared with the prior art, the nuclear power diaphragm valve has the advantages of flexible breakage resistance, fatigue resistance and the like.
Description
Technical field
The utility model relates to a kind of valve, especially relates to the electronic membrane valve of a kind of nuclear power.
Background technique
Membrane valve be with barrier film as open-shut device, drive valve rod by handwheel and move up and down along axis, driver part and medium are in isolation, major function is the medium that switches on or off in the pipeline, the start-stop device that control media is mobile.
Because barrier film is the vital part of the keying and the sealing of membrane valve; The quality of its quality directly has influence on the sealability and the working life of valve; Therefore, the structure of diaphragm of rubber and material will and play crucial effects working life to the sealability of membrane valve.
At present, it is easy to wear, aging that many membrane valves exist barrier film, and many drawbacks such as valve run, drip, leak happen occasionally.
Summary of the invention
The purpose of the utility model is exactly for the defective that overcomes above-mentioned existing technology existence a kind of stiffness breakage, the electronic membrane valve of fatigue proof nuclear power to be provided.
The purpose of the utility model can realize through following technological scheme: the electronic membrane valve of a kind of nuclear power; It is characterized in that this membrane valve mainly is made up of valve body, valve gap, valve rod, barrier film, diaphragm nut, flap, Electric actuator, described valve gap is arranged on the valve body; Described valve body connects barrier film; Described valve rod one end connects barrier film through diaphragm nut, and the other end connects Electric actuator, and described flap connects valve rod.
Described flap connects valve rod through bearing pin, and bearing pin is provided with the pin that prevents that it from coming off.
Be provided with O-ring seals between described valve rod and the valve gap.
Described Electric actuator is connected on the valve gap through flange, is equipped with pad between flange and valve gap and the Electric actuator.
Described valve gap is provided with lifting screw and leak detection bolt.
Compared with prior art; The electronic membrane valve of the utility model nuclear power is a kind of new types of diaphragm valve; Valve body is become stiffness breakage and fatigue performance with diaphragm design, make Korrosionsmedium and all driver parts in the runner be in the state of isolating fully, and increased the leakage-preventing measure of multiple tracks from each position that possibly be easy to generate the leak point; Thereby thoroughly stopped the phenomenons such as " run, drip, leak " of common valve, so has special good decay resistance; Slim and graceful in the operation, rapid, convenient, smooth, be widely used on the domestic and international nuclear power projects.
It can through the analogue signal that Electric actuator sends, in time understand the actual conditions of operating mode medium on the screen in control room, simultaneously valve is carried out remote operation.

Embodiment
As shown in Figure 1; The electronic membrane valve of a kind of nuclear power, this membrane valve mainly are made up of valve body 23, valve gap 17, valve rod 7, barrier film 1, diaphragm nut 3, flap 6, Electric actuator 13, and described valve gap 17 is arranged on the valve body 23; Valve body 23 connects valve gap 17 and barrier film 1 through bolt 22; Bolt 22 is provided with the packing ring 21 that increases bolt 22 nuts 20 screw thread width of cloth locking torques, and valve gap 17 is provided with leak detection bolt 19, can find in time whether the valve barrier film that is in operation damages; Leak detection bolt 19 is provided with and prevents the seal washer 18 revealed, and valve gap 17 and valve body 23 constitute the main parts size of pressure chambers;
Barrier film 1 is to be used for spacer medium to the leakage at valve rod place, is one of leading indicator of examination valve mass performance, is the major part of valve opening and closing element; Barrier film 1 connects valve body 23, and described valve rod 7 one ends connect barrier film 1 through diaphragm nut 3, and the other end connects Electric actuator 13; Barrier film 1 connects diaphragm nut 3 through screw 2, and flap 3 is major parts of valve opening and closing element, and described flap 6 is connected valve rod 7 through diaphragm nut 3 with bearing pin 4; Bearing pin 4 is provided with and prevents its pin that comes off 5; Be provided with O-ring seals 8 between valve rod 7 and the valve gap 17, when preventing that barrier film contingency from damaging, medium is from the leakage of valve gap upper-end surface.
Described Electric actuator 13 is connected on the valve gap 17 through flange 11; Be provided with pad 9 between flange 11 and the valve gap; Reduce the friction between valve gap and the adpting flange; Be provided with pad 12 between flange 11 and the Electric actuator 13, reduce the friction between Electric actuator and the adpting flange, be connected through screw 10 between flange 11 and the Electric actuator 13.Electric actuator 13 is devices of controlling valve with electronic.
Described valve gap 17 is provided with lifting screw 14, is convenient to the lifting and the installation of valve, and valve gap 17 is provided with packing ring 15 through double-screw bolt 16 adpting flanges 11 between double-screw bolt 16 and the flange 11, is used for increasing the moment of double-screw bolt, the locking of the adpting flange screw thread width of cloth.
The keying of the electronic membrane valve of nuclear power is when doing axial motion by Electric actuator actuate valve stem nut, drives flap and barrier film and goes up and down to reach.And can when current interruptions,, make valve opening and closing through rotation hand wheel.When the handwheel clockwise direction rotated, general who has surrendered's path blocked under flap and the barrier film, and valve is promptly closed, otherwise valve is then opened.
The electronic membrane valve of nuclear power is provided with leakage detection apparatus at the valve gap lower end, can find in time whether the valve barrier film that is in operation damages.
Because Sealing is whippy diaphragm of rubber, therefore have better stiffness breakage, endurance and anti-radiation performance.
