Abstract
The utility model discloses an air ball valve comprising a valve body (1), an outer valve cover (7), an inner valve cover (8) and a floating ball (3), wherein the outer valve cover (7) and the inner valve cover (8) are fixed above the valve body (1) by bolts (8), the floating ball (3) is arranged in the valve body (1), a layer of rubber coating (10) is arranged on the outer layer of the floating ball (3), a ball seat (2) is arranged between the valve body (1) and the floating ball (3) and is U-shaped, the floating ball (3) is arranged at the bottom of a U shape, and a layer of pad (4) is arranged at a U-shaped opening part of the ball seat (2). According to the air ball valve provided by the utility model, the replacement frequency of the floating ball is reduced, the valve body is protected, the service life of the air ball valve is prolonged, and the promotion prospect is good.
Description
Technical field
The utility model relates to a kind of intake and exhaust technical field that is used for the transport liquid pipeline, is specifically related to a kind of Air ball valve.
Background technique
Be used for transport liquid pipeline (like water delivery, oil transport pipeline etc.) in order to protect, device power-up such as assurance water pump make, rapidly the air of emptying pipe system; Simultaneously; When equipment such as water pump are shut down suddenly, replenish the air in the pipe-line system rapidly again, prevent that negative pressure is excessive; Destroy input pipeline, main solution is that the eminence in pipe-line system is provided with Air ball valve.At present, Air ball valve commonly used, automatically the intrasystem gas of emptying pipe and in the trend pipeline make-up gas; In the process of emptying and make-up gas, ball float will constantly move at valve body, can produce bigger collision with valve body wall; And the valve body of existing Air ball valve adopts steel structure more, in collision process, can produce bigger wearing and tearing to ball float, needs frequent replacing ball float; Long-term use also can damage valve body, causes the working life of Air ball valve shorter.
The model utility content
The technical problem that the utility model solved is to overcome the valve body that is used for emptying in the existing technology or replenishes the Air ball valve of ducted gas to adopt steel structure more; Ball float is produced bigger wearing and tearing; Need frequent replacing ball float; Long-term use also can damage valve body, causes the short problem in working life of Air ball valve.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of Air ball valve comprises valve body, outer valve gap and interior valve gap and ball float, and said outer valve gap and interior valve gap are through being bolted to the top of valve body; Said ball float is arranged on valve inner; It is characterized in that: the skin of said ball float is provided with one deck encapsulate, also is provided with ball seat between said valve body and the ball float, and said ball seat becomes the U type; Said ball float is placed on U type bottom, and the U type opening portion of said ball seat also is provided with one deck liner.
Aforesaid Air ball valve is characterized in that: said valve body, outer valve gap and interior valve gap all adopt gray cast iron to process.
Aforesaid Air ball valve is characterized in that: said ball seat and liner all adopt insulation rubber to process.
The beneficial effect of the utility model is: the valve body of the Air ball valve of the utility model and valve gap all adopt shock resistance preferably gray cast iron process; At valve inner the ball seat that insulation rubber is processed is set; Can prevent ball float collision to valve interior wall in the process of Air ball valve emptying and make-up gas; And be provided with the good encapsulate of one deck wear resistance at the skin of ball float, thus reduced the replacing frequency of ball float, also effectively protected valve body; Prolong the working life of Air ball valve, had good popularizing prospect.
Description of drawings
Fig. 1 is the structural representation of the Air ball valve of the utility model.
The reference character implication is following:
1: valve body; 2: ball seat; 3: ball float; 4: liner; 5: pad; 6: bolt; 7: outer valve gap; 8: interior valve gap; 9: pore; 10: encapsulate.
Embodiment
To combine Figure of description below, the utility model will be further described.
As shown in Figure 1, Air ball valve comprises valve body 1, outer valve gap 7 and interior valve gap 8 and ball float 3, and outer valve gap 7 and interior valve gap 8 are fixed on the top of valve body 1 through the bolt 6 of both sides; On bolt 6, also be provided with pad 5, can better fix outer valve gap 7, interior valve gap 8 to valve body 1, ball float 3 is arranged on valve body 1 inside, and the skin of ball float 3 is provided with one deck encapsulate 10; Encapsulate 10 has good wear resistance and corrosion resistance, has well protected ball float 3, also is provided with the ball seat 2 that insulation rubber is processed between valve body 1 and the ball float 3; 2 one-tenth U types of ball seat, ball float 3 are placed on U type bottom, and ball float 3 is only limited to the internal motion of ball seat 2; Can prevent ball float collision to valve interior wall in the process of Air ball valve emptying and make-up gas, thereby reduce the replacing frequency of ball float 3, also effectively protect valve body 1; Prolonged the working life of Air ball valve, the U type opening portion of ball seat 2 also is provided with one deck liner 4, and liner 4 also adopts insulation rubber to process; Can not only make Air ball valve have good sealing property, and can also reduce the bump of valve gap 8 in 3 pairs of the ball floats, on valve body 1, be provided with pore 9; Be used for exhaust or inflation, pore 9 can be controlled switching, and pore 9 is opened in exhaust process; After make-up gas, pore 9 to be closed, whole Air ball valve just is in sealing state.
More than show and described basic principle, major character and the advantage of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
