Abstract
The utility model discloses a vacuum compensator. The vacuum compensator comprises a shell, a valve body and a hollow ball, wherein the valve body is arranged in the shell, one end of the valve body is connected with a valve, the other end of the valve body is connected with a pipeline which penetrates through the shell, a limiting ring is arranged in the pipeline, the hollow ball is snapped into the limiting ring, the diameter of the hollow ball is larger than that of the limiting ring. According to the vacuum compensator, the hollow ball is snapped into the limiting ring of the valve body, a role of shell sealing is played in a manner that the hollow ball rises to the limiting ring, and when a water level in the shell falls to a certain extent due to the emergence of a vacuum state, a role of shell vacuum state breaking is played in a manner that the hollow ball falls. According to the vacuum compensator, the vacuum compensation is realized by using the hollow ball, so that the service life of the vacuum compensator is prolonged.

Preferably, described valve is provided with the valve gap for sealed valve body.
Preferably, be provided with breathing pipe in the described shell.
Preferably, described valve body is connected with shell by connection pipe fitting.
Preferably, be provided with peep hole in the described valve body.
Preferably, described hollow spheres is the stainless steel hollow spheres.
Preferably, be connected with on the described shell for the flange that fixes with other objects.
Preferably, the outlet port of described valve is provided with seal ring.
(3) beneficial effect
Technique scheme has following advantage: the utility model is connected to hollow spheres in the position limit cycle in the valve body, utilize hollow spheres to rise to the effect of playing can on the position limit cycle, when when vacuum state occurring and cause that water level drops to a certain degree in the shell, utilize the decline of hollow spheres to play the vacuum state that destroys in the shell.The utility model utilizes hollow spheres to realize vacuum compensation, has prolonged the working life of vacuum compensator.
Description of drawings
Fig. 1 is a kind of embodiment's of the present utility model structural representation.
Wherein, 1: flange; 2: shell; 3: connection pipe fitting; 4: valve body; 5: hollow spheres; 6: position limit cycle; 7: seal ring; 8: peep hole; 9: valve gap; 10: breathing pipe.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, it is a kind of embodiment's of the present utility model structural representation, this vacuum compensator comprises shell 2, valve body 4 and hollow spheres 5, be provided with valve body 4 in the described shell 2, one end of described valve body 4 is connected with valve, and the other end is connected with the pipeline that runs through shell, is provided with position limit cycle 6 in the described pipeline, described hollow spheres 5 is connected in the position limit cycle 6, and the diameter of described hollow spheres is greater than the diameter of described position limit cycle.The utility model is connected to hollow spheres in the position limit cycle in the valve body, utilize hollow spheres to rise to the effect of playing can on the position limit cycle, when when vacuum state occurring and cause that water level drops to a certain degree in the shell, utilize the decline of hollow spheres to play the vacuum state that destroys in the shell.The utility model utilizes hollow spheres to realize vacuum compensation, has prolonged the working life of vacuum compensator.
Valve body of the present utility model is used for realizing the lifting of hollow spheres, and valve body one end is provided with valve, and the other end is connected with pipeline.When water level is very high, form between hollow spheres and the valve body and combine closely, only when water level reduced, hollow spheres descended with water level, thereby had destroyed the vacuum of valve body.Preferably, the other end of valve body 4 is provided with the valve gap 9 for sealed valve body.Outlet port at valve also is provided with seal ring 7, when hollow spheres rises to highest point with water level, utilizes the sealing of seal ring and hollow spheres, has prevented that water from oozing out, and has reached preferably obturation effect.
Be provided with peep hole 8 in the valve body 4 of the present utility model, thereby made things convenient for the situation of observing in the valve body.Be connected with the hollow tubular that leads to housing exterior on this peep hole 8, by this hollow tubular can be in shell visual observation valve body situation.Be fixedly connected with between this valve body 4 and the shell 2, this embodiment is connected with shell 2 by connection pipe fitting 3.Hollow spheres of the present utility model can be various materials, is preferably the stainless steel hollow spheres.
For the ease of the installation of vacuum compensator, preferably, be connected with on the described shell for the fixing flange 1 of other objects.This embodiment respectively is provided with a connecting sheet in the both sides of shell, is fixed connection by this connecting sheet.
Requiring of all parts of the present utility model is as follows:
1. make all parts of vacuum compensator, requiring hollow spheres is stainless steel floating ball, and weight should not surpass 100g and be seamless link.
2. parts valve body 4, position limit cycle 6, seal ring 7, peep hole 8, valve gap 9 are plastic material, and hardness is enough, and the internal thread that matches of valve body 4 cars and connection pipe fitting, screw-thread fit between valve body 4 and the connection pipe fitting.
3. connection pipe fitting 3 is welded on the flange 1, welds appropriate to the occasion rapid welding, avoid making the screw thread on the connection pipe fitting to be out of shape because of heating.
