Detailed Description
The utility model discloses a three-phase mixed transmission one-way valve, and an embodiment of the utility model is specifically described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the three-phase mixing check valve comprises a valve seat 1, a valve body 2 and a supporting seat 3, wherein the valve seat 1, the valve body 2 and the supporting seat 3 are provided with coaxial through holes. As shown in fig. 3 and 4, the valve ball 5 is disposed in the valve body 2 in an adapting manner, and a plurality of protrusions 201 protrude inward from the inner wall of the valve body 2. As shown in fig. 5 and 6, a plurality of flow passages are formed between the adjacent protrusions 201, and the valve ball 5 moves along the inner side wall of the protrusion 201. As shown in fig. 7 and 8, the end of each protrusion 201 away from the valve ball 5 protrudes with a lower limit 202, and the lower limit 202 protrudes inward from the inner side wall of the protrusion 201. As shown in fig. 9 and 10, in the present embodiment, six protrusions 201 are uniformly disposed along the inner sidewall of the valve body 2, and the distance between two opposite lower limits 202 is greater than the diameter of the valve body 2, and the lower limits 202 are used for limiting the valve ball 2, so as to prevent the valve ball from blocking the opening of the supporting seat 3.
As shown in fig. 11, the input end of the valve body 2 is detachably and fixedly connected with the valve seat 1, a sealing ring 4 is detachably connected between the valve seat 1 and the valve body 2, and a sealing ring is arranged between the outer side wall of the sealing ring 4 and the valve body 2. As shown in fig. 12 and 13, the seal ring 4 has a tapered hole coaxial with the through hole of the valve seat 1, the outer diameter of the tapered hole is larger than the pipe diameter of the through hole of the valve seat 1, the inner diameter of the tapered hole is the same as the pipe diameter of the through hole of the valve seat 1, and the valve ball 5 is in contact with the inner diameter of the tapered hole for line sealing. The supporting seat 3 is connected with the valve body 2 through threads, a spring 6 is arranged between the supporting seat 3 and the valve ball 5, and a spring groove 301 is formed around an opening of one end, close to the spring 6, of the supporting seat 3 in a recessed mode. The spring 6 is a conical spring, the small end of the conical spring is contacted with the valve ball 5, and the large end of the conical spring is arranged in the spring groove 301 in a matching way.
Under the action of pressure, the gas, liquid and solid particulate matter mixed medium enters the valve body 2 from the through hole of the valve seat 1 through the sealing ring 4, pushes the valve ball 5 to compress the spring 6 and move downwards along the inner side wall of each bulge 201 until moving to the lower limit 202. The lower limit 202 protrudes inwards from the lower part of the inner side wall of the bulge 201, can limit the valve ball 5, and prevents the valve ball 5 from blocking the opening of the through hole of the supporting seat 3. The valve ball 5 is far away from the sealing ring 4, and gas, liquid and solid particles enter the flow passage of the valve body 2 through the gap between the valve ball 5 and the sealing ring 4. Wherein sealing ring 4 has the bell mouth to the internal diameter of bell mouth is the same with the pipe diameter of disk seat 1 through-hole, and the external diameter of bell mouth is greater than the pipe diameter of disk seat 1 through-hole, can reduce the cavitation erosion, the liquid of mixed medium to the sealing ring and hit and solid particulate matter erodees, and lead to the problem of sealing ring 4 wearing and tearing, increase of service life to sealing ring 4 can change after long-time the use. The flow passage is formed by the gaps between the adjacent protrusions 201 and the valve ball 5, and can be suitable for the flow of gas, liquid and solid particulate matter mixed media. The gas, liquid and solid particulate matter mixed medium enters the supporting seat 3 through the flow channel.
