Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Civil methane voltage-stabilizing stop valve is covered by upper shell 1 and lower shell body 16 and connects and composes.Lower shell body 16 has suction tude 21 and steam outlet pipe 22, and sealing seat 14 and sealing gasket 13 are housed in the hole 24 of the installation usefulness of lower shell body 16, and voltage stabilizing lower spring 12 two ends lean the diapire of sealing seat 14 and lower shell body 16 respectively, and ceramic valve core 15 is packed in the upper end-hole place in hole 24.The bottom bar head of push rod 11 puts in the upper-end surface of close sealing gasket 13 in the ceramic valve core 15, push rod 11 threaded upper end snail rasp bars install diaphragm 9, backing plate 8 back spinning nuts 7, diaphragm 9, backing plate 8 and push rod 11 are tightened together, diaphragm 9 peripheries by upper shell 1 and lower shell body 16 cover press-fit fixing.Spring seat 6 lids are placed on the backing plate 8, and pull bar 3 installs spring seat 6, voltage stabilizing upper spring 5, pressure regulating cover 2, handle spring 4 and threaded cap 20, and there is axis hole pull bar 3 upper ends, and the bearing pin 26 on handle is connected pull bar 3 with handle 19, and pull bar 3 lower ends are boss 28.Pressure regulating cover 2 spinnings are in the hole 25 of upper shell 1, and threaded cap 20 revolves the port in the hole 25 that is enclosed in upper shell 1, and handle spring 5 installs pull bar 3 tops, and the one end leans the pillow block 27 of pull bar 3, and the other end leans threaded cap 20.Ceramic valve core 15 usefulness screws or the fastening upper end-hole that is contained in hole 24 of resin glue, ceramic valve core 15 has seal ring 10 involutions with the hole wall in the hole 24 of lower shell body 16.Covering of upper shell 1 and lower shell body 16 is fastening by six screws 17 and the locking of nut 18 spinnings.When push rod 11 lower end not contact seal of head pads 13, between ceramic valve core 15 and the sealing gasket 14 voltage stabilizing airspace 23 is arranged.Elastomer diaphragm 9 is used for the gas flow space of packing upper shell 1 and lower shell body 16.Owing to threaded cap 20 and handle 19 are housed on the upper shell 1, lift handle 19, drive pull bar 3, spring seat 6, pad 8, diaphragm 9 and through push rod 11 can manual unlocking and close ceramic valve core 15 and sealing gasket 13 between voltage stabilizing airspace 23.Because of pressure regulating cover 2 is housed in the upper shell 1, when dispatching from the factory, can regulate voltage stabilizing airspace 23 by moving up and down of adjusting pressure regulating cover 2 and come pilot line pressure size, reach the purpose of voltage stabilizing.
When valve body of the present invention is in open mode, lift handle 19, by set pressure given in advance, compression voltage stabilizing upper spring 5, can not make pressure regulating cover 2 produce motion to last elastic force, to under elastic force promote spring seat 6, backing plate 8 and elastomer diaphragm 9 and drive push rods 11 and move down, handle spring 4 is in nature and flicks state and tighten handle 19.Contact rubber gasket 13 downwards by push rod 11 lower ends, push rod 11 promotion rubber gaskets 13 and sealing seat 14 are to lower compression voltage stabilizing lower spring 12 simultaneously.This moment rubber gasket 13 with fixing ceramic valve core 15 between have voltage stabilizing airspace 23, biogas enters steam outlet pipe 22 and transports to kitchen range through setting up opened voltage stabilizing airspace 23 in advance by the suction tude on the lower shell body 16 21 at this moment.When handle 19 was shown in an open position, handle spring 4 flicks naturally suitably shifted pull bar 3 onto when dispatching from the factory preset position.
When valve body of the present invention is in closed condition, lift handle 19, handle 19 drives pull bar 3 and moves upward, boss 18 on the pull bar 3 drives spring seat 6 and upwards compresses voltage stabilizing upper spring 5, make voltage stabilizing upper spring 5 be in upwards compressive state, can not promote other component and move, handle spring 4 is in compressive state equally makes two ends all strong, set lever 19.Because push rod 11 lower ends move up and leave sealing gasket 13 upper-end surfaces, voltage stabilizing lower spring 12 is in and flicks freely that state promotes sealing seat 14 and sealing gasket 13 upwards holds out against ceramic valve core 15, the voltage stabilizing airspace 23 of close encapsulation pad 13 and ceramic valve core 15, valve body is in closed condition, and this moment, biogas can not be passed to steam outlet pipe 22 from suction tude 21.
