Abstract
The utility model provides a kind of butterfly valve body with metal backrest, including valve body ontology, the valve body ontology is loop configuration, it is provided with metal backrest in the valve body ontology interior annular structure, the metal backrest cross-sectional width is less than valve body ontology cross-sectional width, the metal backrest section and valve body ontology section axial symmetry, metal backrest center are provided with positioning groove, and the valve body ontology is an integral molding structure with metal backrest；The corresponding position of metal backrest upper and lower ends is equipped with mounting hole, and the utility model overall structure is simple, and the metal backrest being arranged in valve body ontology interior annular structure can make valve seat gum cover preferably be supported and be fixed, and be convenient for changing；Metal backrest center is provided with positioning groove simultaneously, can prevent valve seat gum cover from walking, so that valve seat gum cover is positioned with valve body more acurrate.
Description
Technical field
The utility model belongs to valve technology field, more particularly, to a kind of butterfly valve body with metal backrest.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in structure, currently, when the valve body installation valve seat of existing butterfly valve not
Good positioning, is typically directly sleeved on valve body, and this structure is easily deformed displacement when pressure state or valve plate switch, and causes
Torque and sealing are unstable, in some instances it may even be possible to accident occur.
Invention content
Problem to be solved in the utility model is to provide a kind of simple in structure, prevents valve seat from walking, installs easy to change
Butterfly valve body with metal backrest.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of butterfly valve with metal backrest
Valve body, including valve body ontology, the valve body ontology are loop configuration, and being provided with metal in the valve body ontology interior annular structure leans on
The back of the body, the metal backrest cross-sectional width are less than valve body ontology cross-sectional width, the metal backrest section and valve body ontology sectional axis pair
Claim, metal backrest center is provided with positioning groove, and the valve body ontology is an integral molding structure with metal backrest；Institute
It states the corresponding position of metal backrest upper and lower ends and is equipped with mounting hole.
The metal backrest uses stainless steel.
Valve body body outer surface both sides are symmetrically arranged with weight loss groove.
Due to the adoption of the above technical scheme, the utility model overall structure is simple, is set in valve body ontology interior annular structure
The metal backrest set can make valve seat gum cover preferably be supported and be fixed, and be convenient for changing；Simultaneously at metal backrest center
Position is provided with positioning groove, can prevent valve seat gum cover from walking, and valve seat gum cover is made to position more acurrate, the utility model with valve body
It increases metal to increased by behind overall weight, therefore devises the weight loss groove of valve body both sides to have the function that loss of weight.
The utility model has the beneficial effects that：With simple in structure, prevent valve seat from walking, advantage easy to change is installed.
Description of the drawings
It is specifically described the utility model below with reference to attached drawing and in conjunction with example, the advantages of the utility model and realization
Mode will be more obvious, and wherein content shown in attached drawing is only used for the explanation to the utility model, without constituting to this reality
With it is novel in all senses on limitation, in the accompanying drawings：
Fig. 1 is the utility model structure diagram
Fig. 2 is the sectional view of the utility model valve seat body and metal backrest
In figure：
1, valve body ontology 2, metal backrest 3, positioning groove
4, mounting hole 5, weight loss groove
Specific implementation mode
As depicted in figs. 1 and 2, a kind of butterfly valve body with metal backrest of the utility model, including valve body ontology 1, institute
It is loop configuration to state valve body ontology 1, and metal backrest 2, the metal backrest 2 are provided in the 1 interior annular structure of valve body ontology
Cross-sectional width is less than 1 cross-sectional width of valve body ontology, and 2 section of metal backrest and 1 section axial symmetry of valve body ontology, the metal lean on
It carries on the back 2 centers and is provided with positioning groove 3, the valve body ontology 1 is an integral molding structure with metal backrest 2；The metal leans on
It carries on the back the corresponding position of 2 upper and lower ends and is equipped with mounting hole 4；The metal backrest 2 uses stainless steel；The valve body ontology
1 outer surface both sides is symmetrically arranged with weight loss groove 5.
The utility model overall structure is simple, and the metal backrest 2 being arranged in 1 interior annular structure of valve body ontology can make valve
Seat gum cover is preferably supported and is fixed, and is convenient for changing；2 center of metal backrest is provided with positioning groove 3 simultaneously,
It can prevent valve seat gum cover from walking, so that valve seat gum cover and valve body is positioned more acurrate, the utility model increases whole after metal backrest 2
Body weight increased, therefore devise the weight loss groove 5 of valve body both sides to have the function that loss of weight.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be considered as limiting the scope of the present invention.It is all to become according to impartial made by the scope of the utility model
Change and improve etc., it should all still belong within this patent covering scope.
