The classification of dynamoelectric flange ball valve reachs stainless steel characteristic

Classification:
Breed of dynamoelectric ball valve has: 3 the grey ball valve of 3 ball valve of ball having surplus, fixed ball ball valve, orbit ball valve, V ball valve, ball valve, stainless steel ball valve, forged steel ball valve, discharge, ball valve that fight sulfur, ball valve, pneumatic ball valve, dynamoelectric ball valve, chuck ball valve, solder ball valve, flange ball valve, filar mouth ball valve.
Have float ball: The sphere of ball valve has surplus, below medium pressure effect, the displacement with sure fit of ball physical ability is pressed closely on the sealing surface that exports end, ensure exit end is sealed. The construction of ball valve of ball having surplus is brief, sealing is good, but the load all data transmission that sphere accepts exercise medium gave exit sealing ring, should ponder over sealing ring data consequently whether full taste the work load that gets sphere medium, when be pounded by higher pressure, sphere may break out deflection. This kind is tectonic, use at normally in low-pressure ball valve.
Secure a ball: The sphere of ball valve is fixed, do not break out after press press mobile. Fixed ball ball valve contains valve base having surplus, after getting medium pressure, valve base fit is mobile, make sealing ring is pressed closely on sphere, seal with keeping secret truly. Be in normally with sphere on, lower shaft jacket has bearing, the operation is twisted be apart from small, apply to the valve of high pressure and large requirements. The operation torque to cut down ball valve and raise sealed firm rate, smooth oil, in order to form an oily film, enhanced sealing namely, cut down operation torque again, the ball valve of large requirements of more applicable high pressure.
Stretch ball: The sphere of ball valve is stretch
Sphere and valve base sealing ring choose metallic data to make, sealed very bigger than pressing, the pressure that relies on medium oneself already the request with sealed short of, be necessary to bring to bear on outside force. This kind of valve applies to medium of high temperature high pressure. Stretch sphere is the lower end in sphere wall opens slot of a flexibility, and obtain flexibility. Should close when the passageway, the wedge head of the lever that use a powerful person makes sphere goes up to arrive with valve base impaction sealed. Loosen first before scroll sphere wedge head, sphere subsequently extensive answer original shape, make very little space appears between sphere and valve base, can cut down the conflict of sealing surface and operation torque
Characteristic:
Basic message:
Apply to conduit to press difference big, the switch with sealed severe request and the technical circumstance that intercept conduit medium and fluid are held control a system.
Exercise temperature: - 20 ℃ come + 150 ℃ (+ 250 ℃ are special and sealed) .
Exercise pressure: PN16, PN25 - PN40 - PN64 -PN100
Dimensions:
Air, vapour, water, gas, oil and petrifaction commodity, caustic medium.
Jia of Shanghai of; of dynamoelectric ball valve 100 farming valve, v dynamoelectric ball valve is valve base of a kind of core chooses a metal, or the metal is right get together 4 fluorine ethylene is sealed tosh a powerful person of collaboration, dynamoelectric ball valve had better hold ball valve with butterfly a powerful person accuse characteristic union to become an organic whole, can accuse control valve with do exercise already, can make again close to intercept a powerful person.
Its are main characteristic is:
(1) the put oneself in another's position of integral type a powerful person that does not take any pipe fittings, do not suffer conduit or bolt stress effect consequently, and do not have any pipe fittings because of body of a powerful person, reason compression housing won't suffer pressure “ to change suddenly the influence of ” ;
(2) dynamoelectric ball valve has system of a V a powerful person, although be below the circumstance of little flow or tall viscosity medium, also can be inside whole span dimensions, ensure hold the accuracy that accuse;
(3) the valve base that dynamoelectric ball valve prevents leakage classics to use has in line of place of its external diameter belt form of cup of PTFE of the core inside stainless steel or it is O sealing ring, valve base is used sectional hard alloy makes bigger tungsten cobalt, the moire spring that passes an alloy enhanced the construction of valve base further;
(4) when valve of dynamoelectric ball valve closes, fit wedge cuts the result between V breach and valve base of dynamoelectric ball valve, have already can prevent ball core to get stuck dead again from clean function, dynamoelectric ball valve applies to cop to knot dirty freezes or contain a lot offiber and grain solid circumstance all the more.
Exercise character:
Exercise temperature: - 20 ℃ come + 150 ℃ (+ 250 ℃ are special and sealed) .
Exercise pressure: PN16, PN25 - PN40 - PN64 -PN100
Fluid dimensions
Air, vapour, water, gas, oil and petrifaction commodity, caustic, be like soda acid medium.
