Abstract
The invention discloses a ball-element check valve. The ball-element check valve comprises a valve body and a valve element. The valve element is arranged in a valve cavity of the valve body, an inlet channel is formed in one side of the valve body, and an outlet channel is formed in the other side of the valve body; the valve element is a ball valve element capable of plugging the inlet channel; a limiting block for preventing the outlet channel from being plugged is arranged in the valve cavity. The valve element of the check valve is a ball, the structure is simple, repairing and maintaining are convenient, and cost is low; as rubber lining layers are arranged on the inner wall of the valve body and the outer layer of the valve element, the valve body and the valve element are small in abrasion, long in service life, good in sealing performance, stable and reliable.
Description
Technical field
The present invention relates to valve technology field, especially relate to a kind of Novel ball core safety check.
Background technique
Existing check valve structure is complicated, and manufacture loaded down with trivial details, cost is high, is not easy to maintenance; And existing non-return sealing is poor, and after Long-Time Service, valve inner piece is fragile, causes non-return to lose efficacy, impact uses normally, and reliability is poor.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of ball core safety check, simple to reach structure, uses reliable and stable object.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of ball core safety check, comprise valve body and spool, described spool is located in the valve pocket of valve body, described valve body side is inlet passage, valve body opposite side is outlet passage, and described spool is can the ball valve core of block input port passage, is provided with the limiting stopper preventing from blocking outlet passage in described valve pocket.
Further, described limiting stopper can be the limit rib be located in valve pocket.
Described limiting stopper is provided with the arcuate structure suitable with ball valve core.
Described valve body comprises valve body I and valve body II, and valve body I and valve body II are matched by flanged surface.
The inwall of described valve body is provided with rubber lining valve body layer.
Described ball valve core outer surface is provided with valve core lining glue-line.
Described ball valve core is located in outlet passage.
The present invention compared with prior art, has the following advantages: the spool of this safety check is a spheroid, and structure is simple, is convenient to maintenance, cost is low, and valve interior wall and spool outer are equipped with line with rubber layer, and valve body and spool wear and tear little, long service life, good airproof performance, reliable and stable.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is ball core safety check sectional view of the present invention.
In figure: 1. valve body I, 2. valve body II, 3. limiting stopper, 4. ball valve core, 5. valve body I line with rubber layer, 6. spheroid line with rubber layer, 7. valve body II line with rubber layer.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, this ball core safety check, comprise valve body and spool, spool is located in the valve pocket of valve body, and spool is ball valve core 4; Wherein, valve body comprises valve body I 1 and valve body II 2, to be matched sealing between valve body I and valve body II by flanged surface.
Inlet passage is located in valve body I 1, and outlet passage is located in valve body II 2, and ball valve core 4 is specifically located in outlet passage, and ball valve core can move in outlet passage, and ball valve core moves to inlet passage the inner can block input port passage, realizes non-return.
Inlet passage the inner of valve body I 1 is the globoidal structure of annular, and the curvature of globoidal structure is consistent with the outer surface curvature of ball valve core, non-return good airproof performance; And rubber layer is provided with on globoidal structure, the contact of ball valve core and globoidal structure is flexible contact, very low to the requirement on machining accuracy of globoidal structure and ball valve core while good airproof performance, reduces costs.
Be provided with the limiting stopper 3 preventing from blocking outlet passage in valve pocket, limiting stopper 3 can be the limit rib be located in valve pocket, and limit rib is a pair limit rib, and a pair limit rib is oppositely arranged, and ensures that ball valve core can not block outlet passage, realizes normal media circulation.
Limiting stopper 3 is provided with the arcuate structure suitable with ball valve core, and limit rib is bending plate structure, and cushioning effect is good, reduces the impact of ball valve core, reliable and stable.
Valve body comprises valve body I 1 and valve body II 2, and valve body I and valve body II are matched by flanged surface, is fixed together by two valve bodies through flanged surface by bolt, installation for convenience detach, is convenient to ball valve core and installs and maintenance.Whole ball core safety check mainly comprises four parts, and number of components is few, and structure is simple, and be convenient to manufacture, cost is low.
Flanged surface inside valve body I has part in cavity; The inwall of valve body is provided with rubber lining valve body layer, is specially, and valve body I 1 inwall is provided with valve body I line with rubber layer 5, and valve body II 2 inwall is provided with valve body II line with rubber layer 7, and ball valve core 4 outer surface is provided with valve core lining glue-line 6.Valve body and spool wear and tear little, and spool upset is impacted little, long service life.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technological scheme are carried out; or design of the present invention and technological scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
