Abstract

The utility model discloses a socket and spigot type soft seal butterfly valve which comprises a valve body, a valve shaft, a butterfly plate and a shaft cover. A pipeline is inserted into a flow channel of the valve body, a limiting step is placed on the valve body, and the valve body is further provided with a groove. A sealing ring is arranged in the groove, a wedge flange of a pressing ring is abutted against the sealing ring, the pressing ring is fixedly connected with the valve body through a bolt and a nut, and the pressing ring and the sealing ring are placed on the pipeline in sequence in a sleeved mode. Compared with a flange soft seal butterfly valve, the socket and spigot type soft seal butterfly valve has the advantages that a pipe piece can be directly inserted into the socket and spigot type soft seal butterfly valve, and can be installed conveniently on spot. Corrosion of the pipeline caused by welding can be avoided. The rubber sealing ring is placed at a socket and spigot opening, leakage cannot happen even the pipeline deviates a certain angle because of loading on the outside.

Description

The spigot and socket type soft sealing butterfly valve
Technical field
The utility model relates to a kind of butterfly valve, especially a kind of spigot and socket type soft sealing butterfly valve.
Background technique
Being embedded at present that most of valves on the groundwater supply pipe network are connected with pipeline is to adopt being rigidly connected of flange and bolt, and this Placement produces the concentrated problem of stress unavoidably.Because alternately variation, foundation settlement or the severe cold of road load can cause valve and pipe deforming, cause underground valve to break when serious.In addition, adopt being rigidly connected of flange and bolt need to be on pipeline welded flange, the corrosion-inhibiting coating during welding on the pipeline is destroyed, therefore, the Anticorrosion Problems of flange connection has also become a difficult problem.
Summary of the invention
The purpose of this utility model is exactly to change traditional valve and the flange connection of pipeline, adopts the mode of socket joint that valve is connected with pipeline, to solve the problem of describing in the background technique.
The technical solution of the utility model is: a kind of spigot and socket type soft sealing butterfly valve comprises valve body, valve shaft passes from the through hole on the valve body, rotary seal is connected between valve shaft and the described valve body, valve shaft is provided with butterfly plate, the valve body below is provided with shaft-cup, pipeline is inserted in the described valve flowing channel, it is characterized in that: also comprise
Be sleeved on trim ring and seal ring on the pipeline;
Seal ring is located between valve body and the pipeline;
Trim ring contacts with seal ring;
Trim ring and valve body link together by screw bolt and nut.
Described valve body is provided with limited step.
Preferably, described valve body is provided with groove, and seal ring is located in the groove.
Preferably, described trim ring is fixedly connected with by screw bolt and nut with valve body.
Preferably, described trim ring is provided with flange, and the flange top contacts with seal ring.
Preferably, described valve interior wall runner place is provided with encapsulate.
The beneficial effects of the utility model are: the spigot and socket type soft sealing butterfly valve is compared with the flange soft sealing butterfly valve, and its advantage is:
1. the spigot and socket type butterfly valve directly can insert pipe fitting in it, is convenient to install at the construction field (site).
When 2. the spigot and socket type butterfly valve is installed at the construction field (site), can exempt the corrosive pipeline that causes because of welding.
3. the spigot and socket type butterfly valve is equipped with rubber seal at the bell and spigot joint place, even pipeline can not produce leakage because external load produces certain angle excursion yet.
Description of drawings
Fig. 1 is the structural representation after the installation of spigot and socket type soft sealing butterfly valve
Embodiment
As shown in Figure 1, the spigot and socket type soft sealing butterfly valve, comprise valve body 3, valve shaft 1 passes from the through hole on the valve body 3, be provided with self oiling bearing 2 between valve shaft 1 and the valve body 3, valve shaft 1 is provided with butterfly plate 4, valve body 3 belows are provided with shaft-cup 5, and shaft-cup 5 and valve body 3 are connected by screw fixing, and pipeline 6 is inserted in valve body 3 runners, valve body 3 is provided with limited step, valve body 3 is provided with groove, and seal ring 7 is located in the groove, and the wedge-shaped bead top of trim ring 8 withstands on the seal ring 7, trim ring 8 is connected and fixed with valve body 3 by bolt 9 and nut 10, and trim ring 8 and seal ring 7 successively are sleeved on the pipeline 6.
When tightening nut 10, trim ring 8 is stressed to be moved to the valve central direction, and seal ring 7 seals in the extrusion-deformation of valve body 3 interior pressure rings 8.Simultaneously, its wedge-shaped bead produced the power of vertical pipe 6 axis to pipeline 6 extruding after trim ring 8 was stressed, pipeline 6 is firmly embraced, thereby prevented that pipeline 6 from deviating from valve body 3.

Claims (6)
