Abstract
The utility model relates to a butterfly valve sealing fixed sleeve. The butterfly valve sealing fixed sleeve comprises a valve body and a fixed sleeve body. The fixed sleeve body is locked on the valve body through screws, the fixed sleeve body is provided with holes, and the holes are fixed on the fixed sleeve body and tightly abut against the valve body. Due to the fact that the holes are formed in the fixed sleeve body and tightly abut against the valve body, when the fixed sleeve body and the valve body stick together tightly because of rust stain and are difficult to separate, a user can dismount the holes or the screws, align an oil jack with a screw hole and move the fixed sleeve body relative to the valve body to jack the fixed sleeve body out, then the fixed sleeve body can be separated from the valve body, and convenience and quickness are achieved.
Description
Technical field
The utility model relates to valve field, relates in particular to a kind of butterfly valve seal fixed cover.
Background technique
Butterfly valve is Flap valve again, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.Butterfly valve is meant that closure member (flap or butterfly plate) is a disk, rotates a kind of valve that reaches open and close around valve shaft, and main rising cut off and throttling action on pipeline.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.Butterfly valve is applicable in the engineering systems such as producer, coal gas, rock gas, liquefied petroleum gas (LPG), town gas, cold and hot air, chemical industry smelting and generation environment-friendly and carries on the pipeline of various corrosivity, non-corrosive fluids medium, is used to regulate and block flowing of medium.
Butterfly valve seal fixed cover in the market normally is fixed on the valve body by screw, but, after long-time the use, particularly be in the bigger environment of humidity, stick together because the outer resin layer inefficacy of valve body, the feasible rust that gets rusty are steeped fixed cover and valve body is tightly glutinous, be difficult for separating, particularly when needing repairing, the phenomenon that often occurs not opening takes place.
The model utility content
In view of this, be necessary to provide a kind of after long-term the use, the rust stain occur and fixed cover and valve body are tightly sticked when sticking together the butterfly valve seal fixed cover that still is easy to open during maintenance.
The utility model is achieved in that a kind of butterfly valve seal fixed cover, comprises valve body, fixed cover, and described fixed cover is locked on the described valve body by screw, is provided with the hole on described fixed cover, and described hole is fixed on the described fixed cover, and holds out against described valve body.
Further, the hole on the described fixed cover evenly distributes.
Further, the screw on the described fixed cover evenly distributes.
Further, between described each screw at least one hole is set.
The advantage of the butterfly valve seal fixed cover that the utility model provides is: by the hole is set on fixed cover, and hold out against valve body, when the rust stain tightly sticks together fixed cover and valve body, when being difficult for separately,, using hydraulic jack to aim at screw by removal hole or screw, fixed cover is moved relative to valve body, eject fixed cover, make it separately, convenient and swift.
Description of drawings
Fig. 1 is the structural representation of a kind of butterfly valve seal fixed cover of the utility model.
Fig. 2 installs schematic diagram for the hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, Fig. 1 is the structural representation of a kind of butterfly valve seal fixed cover of the utility model.
Described butterfly valve seal fixed cover, comprise valve body 10, fixed cover 20, described fixed cover 20 is locked on the described valve body 10 by screw 22, screw 22 on the described fixed cover 20 evenly distributes, on described fixed cover 20, be provided with hole 21, described hole 21 is fixed on the described fixed cover 20, and holds out against described valve body 10, and the hole 21 on the described fixed cover 20 evenly distributes.
Another kind of mode of execution is: between described each screw 22 at least one hole 21 is set.
See also Fig. 2, Fig. 2 installs schematic diagram for the hole.
By hole 21 is set on fixed cover 20, and hold out against valve body 10, when the rust stain tightly sticks together fixed cover 20 and valve body 10, when being difficult for separately,, using hydraulic jack to aim at screw by removal hole 21 or screw 22, fixed cover 20 is moved relative to valve body 10, eject fixed cover 20, make it separately, convenient and swift.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
