Abstract
The utility model provides a novel cross-shaped butterfly valve, which comprises a valve body, a valve seat, a butterfly plate and a butterfly rod, and is characterized by also comprising a filtering device, permeating holes, a sealing sleeve and an insulating layer, wherein the butterfly plate is arranged inside the valve body and is a cross-shaped butterfly plate, one side of the butterfly plate is provided with the permeating holes, the outer side of the butterfly plate is provided with the sealing sleeve, and the valve body and the butterfly rod are arranged inside the valve seat. According to the novel cross-shaped butterfly valve, the outer side of the butterfly plate is provided with the sealing sleeve, so that the sealing performance of the novel cross-shaped butterfly valve is improved. The butterfly plate is the cross-shaped butterfly plate, one side of the butterfly plate is provided with the permeating holes, when small-flow liquid conveying is needed, the novel cross-shaped butterfly valve can be turned to the side provided with the permeating holes, and delivered liquid passes through the butterfly plate with the permeating holes, so that the goal of small-flow delivery is achieved.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of cross butterfly valve.
Background technique
Butterfly valve is again Flap valve, is a kind of modulating valve simple in structure, and butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates to reach a kind of valve of open and close around valve shaft, and on pipeline, main rising cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.Butterfly valve now, structure is comparatively simple, can only open or close in use flow, although want to realize low flow rate liquid circulation if can realize adjust flux, butterfly valve now can not reach good effect.Butterfly valve also can be applied in the liquid conducting pipes that temperature is higher, and the temperature of liquid can be sent on butterfly valve so in use, is unfavorable for that user carries out switch to valve.Flowing liquid in delivery pipe has the existence of impurity sometimes, when by butterfly valve, extremely easily by valve blockage, causes valve to use inconvenient, affects liquid and carries.
Summary of the invention
According to above technical problem, the utility model provides a kind of novel cross butterfly valve, comprise valve body, valve seat, butterfly plate, butterfly bar, characterized by further comprising filtrating equipment, permeability hole, stuffing box gland, thermal insulation layer, described valve inner is provided with butterfly plate, described butterfly plate is cross butterfly plate, described butterfly plate one side is provided with permeability hole, described butterfly plate outside is provided with stuffing box gland, described valve inner is provided with valve seat and butterfly bar, described butterfly bar upside is provided with thermal insulation layer, described butterfly bar is connected with butterfly plate, described valve body and pipeline junction are provided with filtrating equipment, described valve block outside is provided with thermal insulation layer.
Described filtrating equipment is demountable structure.
The utility model beneficial effect is: the utility model has increased filtrating equipment, permeability hole, stuffing box gland, thermal insulation layer, filtrating equipment can filter managing interior flowing liquid, fall transmitting the contaminant filter existing in liquid, can be easily by clean the liquid filtering transmitting, filtrating equipment can be disassembled when using after a period of time, then it is cleaned, avoid carrying and stop up.The utility model valve body arranged outside has thermal insulation layer, thermal insulation layer not only can ensure to transmit the temperature of liquid, also the temperature and the external world that transmit liquid can be kept apart, in the time that transmission fluid temperature is too high, because have effect the utility model outside of thermal insulation layer can't be subject to the impact of temperature, can't be subject to the impact of inside temperature in the time that operator use.Butterfly plate of the present utility model outside is provided with stuffing box gland, has increased sealing of the present utility model.Butterfly plate of the present utility model is cross butterfly plate, and a side of butterfly plate is provided with permeability hole, in the time needing small flow to carry liquid, the utility model can be forwarded to the side with permeability hole, transmits liquid by the butterfly plate of permeability hole, reaches the object that small flow transmits.
Brief description of the drawings

Fig. 3 is the utility model filtrating equipment schematic diagram;
As shown in Figure 1, Figure 2, Fig. 3, valve body-1, valve seat-2, butterfly plate-3, butterfly bar-4, filtrating equipment-5, permeability hole-6, stuffing box gland-7, thermal insulation layer-8.
Embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, the utility model is further described:
Embodiment 1
The utility model is a kind of cross butterfly valve, comprise valve body 1, valve seat 2, butterfly plate 3, butterfly bar 4, filtrating equipment 5, permeability hole 6, stuffing box gland 7, thermal insulation layer 8, butterfly plate is cross butterfly plate 3, butterfly plate 3 one sides are provided with permeability hole 6, butterfly plate 3 outsides are provided with stuffing box gland 7, valve body 1 inside is provided with valve seat 2 and butterfly bar 4, butterfly bar 4 upsides are provided with thermal insulation layer 8, valve body 1 is provided with filtrating equipment 5 with pipeline junction, valve seat 2 outsides are provided with thermal insulation layer 8, valve seat 2 inside are provided with butterfly plate 3, and butterfly plate 3 is connected with butterfly bar 4.
Embodiment 2
In use, inner filtrating equipment 5 filters the impurity in pipe, improve the quality that transmits liquid, in the time that needs liquid small flow flows, forward butterfly plate 3 of the present utility model to a side with permeability hole 6 by rotating butterfly bar 4, stuffing box gland 7 is installed on butterfly plate 3, can improves the sealing between butterfly plate 3 and valve body 1.In the time that the large flow liquid of needs flows, forward butterfly plate 3 of the present utility model to the not side with permeability hole 6 by rotating butterfly bar 4, liquid strengthens by flow.When the utility model internal flow be the higher liquid of temperature time, because the utility model inside is provided with thermal insulation layer 8, the temperature of liquid can be completely cut off in inside, in the time using the butterfly lever switch of the utility model outside, the impact of inside temperature can not received in outside of the present utility model.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
Claims (2)
