Detailed Description
As shown in the figure, the one-way valve device comprises a valve body 8, a valve core component is arranged in the valve body 8, the liquid outlet end of the valve body 8 is communicated with a detachable joint 7, in the embodiment, the joint 7 is in threaded connection with the liquid outlet end of the valve body 8, and the joints 7 of different types can be replaced according to the needs by connecting the joints 7 with the valve body 8, so that connecting pipes of different sizes are connected, and the applicability is wide. The liquid inlet with adjustable opening size is arranged at the liquid inlet end of the valve body 8, and in the embodiment, the liquid inlet is mainly realized in the following manner: the liquid inlet end of the valve body 8 is communicated with a movable liquid inlet sleeve 6 which is matched, specifically, an external thread is arranged at the liquid inlet end of the valve body 8, an internal thread which is matched with the external thread is arranged on the liquid inlet sleeve 6, the liquid inlet sleeve 6 is connected with the valve body 8 in a threaded manner, through holes are formed in the peripheral wall of the liquid inlet sleeve 6, four through holes which are positioned on the same horizontal plane are uniformly formed in the peripheral wall of the liquid inlet sleeve 6 in order to ensure uniform and accurate flow control, an axial gap formed between the bottom end wall of the valve body 8 and the through holes is a liquid inlet, and an opening is formed in the bottom end of the valve body 8. When the size of the liquid inlet is regulated, the opening and closing and the size of the liquid inlet can be controlled by only rotating the liquid inlet sleeve 6 up and down on the valve body 8. In addition to the manner of providing the through hole on the liquid inlet sleeve to adjust the liquid inlet in this embodiment, there are other manners, such as providing a through hole on the peripheral wall of the liquid inlet end of the valve body, and controlling the size of the through hole by moving the liquid inlet sleeve.
In order to prevent the liquid inlet sleeve 6 from falling off after being connected to the valve body 8 in a threaded manner, a first clamping groove is formed in the inner wall of the liquid inlet sleeve 6 and above the internal thread of the liquid inlet sleeve, a first clamping spring 10 matched with the liquid inlet sleeve is arranged in the first clamping groove, and the first clamping spring 10 can prevent the internal thread from unscrewing from the external thread, so that a good limiting effect is achieved. In this embodiment, the through hole is disposed below the internal thread, when the through hole moves along with the liquid inlet sleeve 6 on the valve body 8 toward the joint 7, the gap between the through hole and the valve body 8, that is, the size of the liquid inlet, will gradually decrease, otherwise, gradually increase, and the size of the through hole is not larger than the maximum, so as to help the liquid inlet sleeve 6 screwed on the valve body 8, to prevent the liquid from leaking out of the liquid inlet sleeve 6, a sealing pad 1 is further disposed on the inner bottom surface of the liquid inlet sleeve 6, and the valve body 8 can be screwed to a position where the sealing pad 1 is tightly adhered.
The valve body 8 is provided with a valve core cavity and a filter cavity which are communicated, the valve core cavity is close to the joint 7, the filter cavity is close to the liquid inlet sleeve 6, the valve body 8 is internally provided with an annular flange between the valve core cavity and the filter cavity, one surface of the annular flange, which faces the valve core cavity, is provided with a sealing gasket 4, the valve core assembly comprises a valve core, a spring and a fixing frame, the valve core cavity is internally provided with a valve core 3 which is contacted with the sealing gasket, the sealing gasket 4 and the valve core 3 are matched with each other to have good sealing effect when liquid is reversely fed, the valve core 3 is provided with a valve rod, the valve rod is sleeved with the spring 5, a fixing frame 2 which is matched with the valve core 3 is arranged above the spring 5, the fixing frame 2 is also provided with a valve rod hole which is matched with the valve rod, and the fixing frame 2 is matched with the inner cavity of the joint 7. When liquid enters the valve body 8 positively, the valve core 3 moves towards the joint 7 under the pressure of the liquid and flows out of the gap between the valve core and the annular flange, so that the liquid can pass through the gap, and the valve rod also moves towards the fixed frame 2 along with the movement of the valve core 3 and passes through the valve rod hole, so that the movement of the valve core 3 is prevented from being hindered.
The filter screen 11 is arranged in the filter cavity, the filter screen 11 can filter liquid firstly, then the liquid enters the corresponding pipeline through the joint 7, and the liquid with impurities is prevented from precipitating on the pipeline or corresponding application equipment, so that the service life of the liquid is influenced. A second clamping groove is formed in the inner wall of the valve body 8 at the liquid inlet side of the filter screen 11, a second clamping spring 9 matched with the second clamping groove is arranged in the second clamping groove, the second clamping spring 9 can clamp the filter screen 11, and the filter screen 11 is prevented from falling off from the filter cavity
In conclusion, through connecting 7 threaded connection on valve body 8, can change the joint 7 of different models as required to connect not unidimensional takeover, extensive applicability, in addition, can also control the feed liquor flow, have good result of use. Even if the joint 7 is damaged, the replacement cost is low, and the use cost of enterprises is saved.
