Abstract
The utility model discloses a water seal butterfly valve which comprises a butterfly plate, a valve body and a connector. The valve body is provided with a seal valve base, and the seal valve base is matched with the butterfly plate to form seal pairs. The valve body is provided with a connector groove and a valve body flange. A connector through hole penetrates through the connector, the connector is provided with a connector flange, one end of the connector is embedded in the connector groove, a sealing ring is arranged between the valve body flange and the connector flange, the end, adjacent to the butterfly plate, of the seal valve base is provided with a sealing groove, a valve base channel is arranged between the sealing groove and the connector groove, and the sealing groove is communicated with the connector through hole through the valve base channel. The sealing face of the seal valve base of the valve body of the water seal butterfly valve is divided into two portions; when the valve is shut off, water can be injected through the connector through hole, water seal is formed between the two seal pairs, and media in a pipeline are prevented from being leaked; when the media leak into water, the media can be discharged through the valve base channel and the connector through hole, and cannot be leaked into the lower course of the pipeline.
Description
Technical field
The utility model relates to valve field, particularly a kind of Water seal butterfly valve.
Background technique
Valve plays effect through-flow and that cut off in pipe-line system, medium in some pipeline belongs to inflammable, explosive gas, if there is leaking, will cause serious accident, especially be used as the maintenance cutting-off valve of the medium of coal gas, requirement for valve seal is especially strict, and the sealing of existing valve substantially all cannot reach requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of Water seal butterfly valve that tightly, effectively prevents any type of leakage that seals.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of Water seal butterfly valve, comprise butterfly plate, valve body and joint, on valve body, be provided with seal valve seat, the seal valve seat formation sealing pair that matches with butterfly plate, on valve body, be provided with connector slot and valve body flange, joint is penetrated with joint through hole, and on joint, be provided with fitting flange, joint one end embeds in connector slot, between valve body flange and fitting flange, be provided with seal ring, wherein, one end that seal valve seat and butterfly plate are adjacent is provided with seal groove, between seal groove and connector slot, be provided with valve base channel, seal groove is connected with joint through hole by valve base channel.
Adopt Water seal butterfly valve of the present utility model to have the following advantages:
1, the sealing surface of the seal valve seat of valve body is divided into two-part, when valve closing, can pass through joint through hole injected water, between two sealing pairs, forms water seal, avoids the leakage of pipeline medium;
2, when having dielectric leakage in water time, can discharge via valve base channel and joint through hole, and can not leak to pipeline downstream;
3, structure is not had to special requirement, versatility is extremely strong, can be widely used in playing in pipe-line system effect through-flow and that cut off.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Water seal butterfly valve.
Fig. 2 is the detailed drawing of A portion in Fig. 1.
Fig. 3 is the detailed drawing of B portion in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, be Water seal butterfly valve of the present utility model, wherein, 1 is butterfly plate, and 2 is valve body, and 3 is joint, and 201 is seal valve seat, and D is water intake, and C is water outlet.Seal valve seat 201 is arranged on valve body 2, and the seal valve seat 201 formation sealing pair that matches with butterfly plate 1.
As shown in FIG. 2 and 3,202 is connector slot, and 203 is valve body flange, and 301 is joint through hole, and 302 is fitting flange, and 4 is seal ring, and 5 is seal groove, and 6 is valve base channel, and 7 for sealing one, 8 is for sealing two.Connector slot 202 and valve body flange 203 are arranged on valve body 2, and joint 3 is penetrated with joint through hole 301, and fitting flange 302 is arranged on joint 3, and joint 3 one end embed in connector slot 202, and seal ring 4 is arranged between valve body flange 203 and fitting flange 302.Seal groove 5 is arranged at one end that seal valve seat 201 is adjacent with butterfly plate 1, and valve base channel 6 is arranged between seal groove 5 and connector slot 202, and seal groove 5 is connected with joint through hole 301 by valve base channel 6.
When butterfly plate 1 is closed, the sealing surface of the sealing surface of butterfly plate 1 and seal valve seat 201 forms sealing 1 and sealing 28, when press water enters seal groove 5 from water intake D, forms watertight seal ring one, can guarantee that medium do not reveal.Even if there is medium to pass through sealing 1 and entered into seal groove 5, also can discharge from joint 3, can through sealing 28, not arrive pipeline downstream again, so just guaranteed the safety of downstream line, realize effectively sealing.
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 improvement also should be considered as protection domain of the present utility model.
