Abstract
The utility model relates to a valve device, specifically speaking are ball check valves. The valve body is divided into a front valve body, a rear valve body and a ball body, wherein an axial rib plate is arranged in the valve body, and the ball body is a moving part of the valve body and can move in a cavity formed by the front valve body and the rear valve body. The utility model discloses simple structure, sealing performance is good, and no seepage is with low costs, and the vibration is little, noiselessness, easy maintenance, long service life. Is suitable for small-caliber water supply equipment.
Description
Technical field: the utility model relates to a kind of valving, specifically a kind of ball check valve.
Background technique: according to the knowledge of the applicant, the safety check that uses mainly contains two kinds at present: a kind of is spring loaded check valve; Another kind is a Swing check valve.These two kinds of its valve seats of safety check and valve plate all adopt metal to make, in the process of processing and assembling, there is error just to be difficult to guarantee that valve seat and valve plate can closely cooperate slightly, and because gapped existence between each part, the relative position of valve seat and valve plate all can produce mobile, therefore, can not guarantee all can close each time very tight.And in the process of closing, can produce very big resistance, consume a large amount of energy.Simultaneously, in frequent switching surge process, will certainly cause rubbing of sealing surface to hit, shorten its working life.This kind valve can damage in water in very fast corrosion, makes safety check malfunctioning.
Summary of the invention: technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provides a kind of simple in structure, good seal performance, the ball check valve that the life-span is long.
The technological scheme that its technical problem that solves the utility model adopts is a kind of ball check valve, it is provided with valve body, it is characterized in that valve body divides front valve shell, rear valve body and spheroid, is provided with axial gusset in the valve body, spheroid is the movable part of valve body, and it can move in the cavity that forward and backward valve body is formed.
The utility model spool is a ball-type, and this fairshaped spool can reduce the resistance of water greatly, thereby energy consumption is reduced, and has saved the energy.It is simple in structure, good seal performance, ne-leakage, preparation process is simple, cost is low, vibrate little, noise free, easy to maintenance, long service life.
Description of drawings: the utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is another example structure schematic representation of the utility model.
Fig. 3 is that the A-A of Fig. 1 and Fig. 2 is to sectional view.
Embodiment: among Fig. 1, ball check valve, it is provided with valve body.Valve body divides front valve shell 1, rear valve body 3, spheroid 2 and axial gusset 6.Spheroid 2 is the movable part of valve body, and it is the software solid sphere, can move in the cavity that forward and backward valve body is formed, to reach the open and close effect to safety check.Be provided with axial gusset 6 in the valve body, several axial gussets directly constitute the flowing space of the activity space and the medium of spheroid, as shown in Figure 3.Among Fig. 2, spheroid is the hardware solid sphere, can establish sealing gasket 4 and pad 5 between the forward and backward valve body.As can be seen, a kind of ball type non-return valve sealing surface of the utility model adopts one soft one hard material to make, and does not have friction each other from Fig. 1 and Fig. 2, and impact force is very little, in conjunction with tight, and can seepage.In addition, the utility model obturator all adopts materials such as corrosion-resistant, ageing-resistant glass, pottery, plastics, rubber to make, and prolong working life greatly.The utility model in use when water flows into front valve shell, is pushed ball the right-hand member (dotted line position among the figure) of valve body to, and water is by being that rear valve body is flowed out at the cavity place of rear valve body around the spheroid; When water supply stops, because the pressure effect of water behind the valve, push ball the left end of valve body to, the water intake of front valve shell is stopped up, water can not be refluxed, play the effect of non-return.
The utility model is simple in structure, good seal performance, ne-leakage, cost is low, vibrate little, noise free, easy to maintenance, long service life.Being suitable for small-bore water supply equipment uses.
Claims (3)
1 one kinds of ball check valve, it is provided with valve body, it is characterized in that valve body divides front valve shell, rear valve body and spheroid, is provided with axial gusset in the valve body, and spheroid is the movable part of valve body, and it can move in the cavity that forward and backward valve body is formed.
2 safety check according to claim 1 is characterized in that said spheroid can be software.
3 safety check according to claim 1 is characterized in that can establishing sealing gasket and pad between the said forward and backward valve body.
