Abstract
The utility model relates to a seawater resistant rubber lined eccentric butterfly valve which comprises a valve body and a butterfly plate positioned in the valve body, wherein a valve body seal ring used as a valve seat is fixedly installed in the valve body, a butterfly plate seal ring forming a seal pair together with the valve body seal ring is arranged on the butterfly plate, a lining isolated from the medium is arranged on the inner surface of the valve body not covered by the valve body seal ring, the valve body is casted with carbon steel, the lining is a rubber lining, the valve body seal ring is made of seawater resistant stainless steel material, the butterfly plate seal ring is made of seawater resistant stainless steel material or rubber material, the butterfly plate can be made of seawater resistant stainless steel material or carbon steel outside which a rubber wrapping layer is arranged, and an eccentric structure is adopted among the butterfly plate, the valve rod and the valve body. The seawater resistant rubber lined eccentric butterfly valve has low production cost, good sealing performance and good corrosion resistance, is convenient to operate and maintain, and is mainly used for transporting the seawater and other corrosive medium and is suitable for other occasions.
Description
Technical field
The utility model relates to a kind of sea water resistance line with rubber eccentric-butterfly-valve, the occasion that mainly can be used for carrying Korrosionsmediums such as seawater, the occasion that also can be used to carry other media.
Background technique
The existing valve that is used to carry Korrosionsmedium such as seawater, the center line soft sealing butterfly valves that adopt more, mainly form by valve body, butterfly plate and valve rod, relative valve body of valve rod and butterfly plate do not have off-centre, center line by valve body and butterfly plate, the defective one of this butterfly valve is to need to adopt corrosion resistant stainless steel material, the cost height, and be difficult to butterfly plate is dismantled maintenance.
The model utility content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of sea water resistance line with rubber eccentric-butterfly-valve, and this butterfly valve cost is low, and easy to maintenance.
The utility model realizes that the technological scheme of above-mentioned purpose is: a kind of sea water resistance line with rubber eccentric-butterfly-valve, comprise valve body and the butterfly plate that is positioned at valve body, described butterfly plate is installed on the valve rod, described valve rod is rotatably connected with described valve body, described valve body internal fixation is equipped with the valve seals as valve seat, described butterfly plate is provided with the butterfly plate seal ring that constitutes sealing pair with described valve seals, described valve seals adopts the stainless steel material of sea water resistance, and be welded in the valve body, be equipped with on the internal surface that described valve body is not covered by described valve seals and be used for the lining isolated with medium.
Owing to be used for the lining of isolated medium internal surface being provided with of valve body, therefore valve body itself does not need to have decay resistance, therefore can adopt low price material such as carbon steel to make, in the assurance antiseptic effect, reduce the cost of production of butterfly valve significantly thus.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model the partial structurtes schematic representation that relates to valve body, valve seals, butterfly plate and butterfly plate seal ring;
Fig. 2 is the another kind of embodiment's of the utility model the partial structurtes schematic representation that relates to valve body, valve seals, butterfly plate and butterfly plate seal ring.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of sea water resistance line with rubber eccentric-butterfly-valve, the butterfly plate 8 that it comprises valve body 1 and is positioned at valve body, described butterfly plate is installed on the valve rod, described valve rod is rotatably connected with described valve body, described valve body internal fixation is equipped with the valve seals 3 as valve seat, described butterfly plate is provided with the butterfly plate seal ring 4 that constitutes sealing pair with described valve seals, be equipped with on the internal surface that described valve body is not covered by described valve seals and be used for the lining 2 isolated, avoid the corrosion of medium thus valve body with medium.
Usually, described valve seals can adopt the stainless steel material of sea water resistance, and is welded in the valve body.
Usually, described valve body can adopt cast carbon steel to form, and can be provided with one or more machining faces, to satisfy corresponding surface requirements.
Described lining is preferably rubber lining, with the working life that possesses good anti-corrosion and grow, and is convenient to processing.
The preferred eccentric structure that adopts with easy disassembly and maintenance, and guarantees good sealing characteristics and acting characteristic between described butterfly plate, valve rod and the valve body three, reduces wear and resistance, increases the service life.
Described butterfly plate seal ring is provided with on the set-up mode on the described butterfly plate can be for described butterfly plate with the fastening pressing plate 5 of fastening screw 6, described butterfly plate seal ring is clamped between described butterfly plate and the described pressing plate, its outer rim is exposed at the outside of the cylindrical of described butterfly plate and described pressing plate, form and the contacted sealing surface of described valve seals (or line) thus, for guaranteeing the fastening effect of fastening screw trip bolt, can be provided with compression spring 7 under the described fastening screw trip bolt.
In the embodiment shown in fig. 1, described butterfly plate, pressing plate, fastening screw can all adopt the stainless steel material of sea water resistance, with convenient processing.
In the embodiment shown in Figure 2, described butterfly plate also can adopt carbon steel to make, its outer surface is provided with and is used for the rubber coating 9 isolated with medium, described pressing plate and fastening screw can adopt the stainless steel material of sea water resistance, because the material consumption of described butterfly plate is much larger than pressing plate and fastening screw trip bolt, can reduce cost of material effectively thus, and take into account the facility in the processing.
