Et papilio laminam depapilio valvuminstalled in diameter fistula. Papflfly valvae habet simplex structuram, parva magnitudine, lux pondus, tantum pauci partes, et solum indiget ad Rotate XC ° ut celeriter aperta et prope, simplex ut agunt, et valvae habet bonum fluidum imperium habet, et valvae habet bonum fluidum imperium habet, et valvae habet bonum fluidum imperium habet, et valvae habet bonum fluidum imperium habet, et valvae habet bonum fluidum imperium habet, et valvae habet bonum fluidum imperium characteres. Cum papilio valvae in plene aperta situ, crassitudo papilio laminam resistentia medium cum fluit per valvae corpus, ita pressura gutta generatas per valvae est valde parvum, ita est bonum influere a valvae est valde parvum, ita est bonum influere a valvae est valde parvum, ita est bonum influere a valvae est valde parvum, ita est bonum fluere potestate.
Sipapilio valvumEst requiritur utendum est ut fluxus potestate, pelagus res est eligere rectam magnitudine et genus valvae. Structural principium papilio valvulae praecipue idoneam facere magna diametro valvulae. Sunt duo communiter usus papilio valvulae: Fibulae-genus papilio valvae et fulvum papilionem valvae. Fibulae papilio valvae ad coniungere valvae inter bipeline flanges cum BOLLING et Flagy papilio valvae est valvae cum Pipeline flanges cum fines.
Ut a component solebat, ut animadverto in-off et influunt imperium of Pipeline ratio, papilio valvae est late in multis agris ut PETROLEUM, chemical industria, MetallurGy, Hydropoture, et sigillatim in formam est maxime signing structure, et ob signa, quod est maxime ad structuram, et ob signans, quod est in limitatione etc. Nam summus temperatus resistentia, princeps pressura resistentia, corrosio resistentia, gerunt resistentia et alia industries.
In praesenti, a relative provectus papilio valvae est tria-eccentrici metallum durum sigillum papilio valvae, valvae corpus et valvae sedes conjuncta components et superficiem et admodum et corrosio sigillum sigillum sigillum et temperatus est, repugnant et corrosio, repugnant sigillum materiae. The multi-layer soft-stacked sealing ring is fixed on the valve plate, this kind of butterfly valve has high temperature resistance compared with the traditional butterfly valve, light operation, frictionless opening and closing, and compensates for the seal with the increase of torque of the transmission mechanism when closing, which improves the sealing performance of the butterfly valve and the advantages of prolonging the service life.
Tamen hoc papilio valvae adhuc habet sequens problems per usum:
1. Since the multi-layer soft and hard stacked sealing ring is fixed on the valve plate, when the valve plate is normally open, the medium forms a positive scouring on its sealing surface, and the soft sealing belt in the metal sheet interlayer is directly affected by the erosion.
II. Structuralis conditionibus structura non apta valvulae diametris infra DN200, quia altiore structuram valvae laminam est densissima et fluxus resistentia magna.
3. Due to the principle of three eccentric structure, the sealing between the sealing surface of the valve plate and the valve seat is to press the valve plate to the valve seat by the torque of the transmission device. In positivum influunt statum, in altiorem medium pressura, et tighter signa et extrusionem. Cum autem fluunt alveo medium est reversed, cum incremento medii pressura, quod unitas positivum pressura inter valvae laminam et valvae sedem est minus quam medium pressura et sigillum incipit ad Leak.
Et summus perficientur tres-eccentrici duo-via durum sigillum papilionem valvae, in quibus, in valvae sedes signantes annulum est ex multa stratis immaculatam ferro laminas in utrinque. Et signantes superficies de valvae laminam et valvae sedes est obliquus conica structuram et temperatus repugnans et corrosio-repugnans stilo materiae sunt surfacing in superficiei obliquus pyramidis valvae laminam; A structuram in quo vere fixum inter adjusting anulum pressura laminam et ad aptenting fulmine in pressura laminam convenerunt in unum.
Hoc structuram efficaciter compensat ad tolerantia zonam inter paludes sleeve et valvae corpus et elastica deformatio valvae derivantur in medium pressura, et solvit ad problema ad valvae, et solvit, in processus of duos-vecturae intervicientable media translationem. Signatio anulum est composita ex multi-layer immaculatam ferro laminas in utrinque in mollis T-figura, quae habet duplicem commoda metallum dura signing et mollis perficientur, et having et caliditas et caliditas.
The test proves that when the tank is in the positive flow state (the medium flow direction is the same as the rotation direction of the butterfly plate), the pressure of the sealing surface is generated by the torque of the transmission device and the effect of the medium pressure on the valve plate. Cum pressura de deinceps medium crescit, quod arctius et expressa de obliquo cone superficiem valvae laminam et signantes superficies de valvae sede, melior signing effectus. In reverse influunt statum, sigillum inter discus et sedes premitur contra sedem a torque actuator. Cum incremento de pressura de vicissim medium, cum unitas positivum pressura inter cylva laminam et valvae sedem est minus quam in pressura, deformatio et signat in stricta ad valvae et in laminam et signantes superficies in valvum ad ludere in automatic et in aurei in cinaccos et in latitudinem et in aureum et in cinaccos et in latitudinem in aureum et in latitudinem et in aureum in aureum in aureum in aureum et in aureum in aureum in aureum in aurei et in latitudinem in aureum et in aureum in aureum in ciligam et in latitudinem in valvae et in latitudinem et in aureum in aureum in aureum ad ludere in automatic et in cylva in aurei ad ludere a cystema. Therefore, the utility model discloses is not like the prior art, a soft and hard multi-layer sealing ring is installed on the valve plate, but is directly installed on the valve body, and an adjusting ring is very ideal two-way hard sealing mode is added in the middle of the pressing plate and the valve seat. Eam reponere porta valvulae, globe valvulae et pila valvulae.
