Abstract
A novel combined valve comprises a check valve body and a butterfly valve body. The check valve body and the butterfly valve body are connected and fixed through welding. The check valve body is provided with a valve cover, a valve core and a valve core base. The butterfly valve body is provided with an upper valve body, a lower valve body and a fixing sleeve. The upper valve body and the lower valve body are connected and fixed through connecting holes in protruding platforms and a bolt. The valve cover and the check valve body are connected through threads. The valve core base is welded to the connecting portion of the check valve body and the butterfly valve body, and the center of the valve core base is provided with a circular hole. A butterfly plate and a valve rod are arranged at the connecting position of the upper valve body and the lower valve body on the butterfly valve body. A sealing ring is arranged at the contact position of the butterfly plate and the butterfly valve body. The valve rod is provided with a handle sleeve arranged in the fixing sleeve, one end of the valve rod is connected with the butterfly plate, and the other end of the valve rod is connected with a handle rod through the handle sleeve arranged on the valve rod.
Description
Technical field
The utility model relates to valve field, particularly a kind of combined valve.
Background technique
The technology that after existing pump, rising pipe connects at present, be by short tube flange, safety check, add the parts such as short tube flange, butterfly valve again and connect into outfall sewer after pump by a lot of clamping bolts, the function that opens and closes, prevents aqueous reflux to reach pipeline, this kind of technological means installed complexity, safeguards also more difficult.
Summary of the invention
In order to overcome the drawback existing in prior art, the utility model has designed a kind of novel combination brake switch and proporting being combined by safety check and butterfly valve.
A kind of novel combination brake switch and proporting comprises check valve body and butterfly valve body, check valve body and butterfly valve body are fixing by being welded to connect, in check valve body, be provided with valve gap, spool and valve core base, on butterfly valve body, be provided with upper valve body, lower valve body and fixed cover, on upper valve body and lower valve body, be provided with raised platforms, in raised platforms, be provided with attachment hole, upper valve body and lower valve body are fixed with bolts by raised platforms attachment hole, described valve gap and check valve body are threaded connection, valve gap and check valve body contact position are provided with valve bonnet seal circle, on valve gap, be provided with dismounting groove, on spool, be provided with valve core seal ring and valve core rod, valve core base welding is arranged on check valve body and butterfly valve body joint, valve core base central position is provided with circular hole, pore size and valve core rod match, the upper valve body arranging on described butterfly valve body and lower valve body link position are provided with butterfly plate and valve rod, butterfly plate and butterfly valve body contact position are provided with butterfly valve seal circle, on described valve rod, be provided with handle jacket, handle jacket is arranged in fixed cover, valve rod one end is connected with butterfly plate, the other end is connected with handlebar by the handle jacket being arranged on valve rod, and handlebar is connected one end with valve rod and is provided with handle spring, and the handlebar the other end is provided with handle.
Described check valve body and butterfly valve body contact position end adopt two platform structures, upper platform contacts with butterfly valve body, lower floor's platform contacts with check valve spool base, on butterfly valve body and the check valve spool floor installation two platform structures in check valve body after by seamless welding fixing seal.
a kind of beneficial effect of novel combination brake switch and proportingthe design is by adopting two structure for mounting platforms that check valve body and butterfly valve body are combined, on the valve gap of check valve body part, be provided with dismounting groove simultaneously, not only saved the short tube flange that adopts in conventional art, safety check, added numerous parts such as short tube flange, butterfly valve again and connect into outfall sewer miscellaneous work after pump by a lot of clamping bolts, in the work of later maintenance also because the numerous component disassemble and assemble works in the middle of having saved, simultaneously also because the dismounting groove structure newly increasing becomes more easy.
