Detailed Description
Referring to fig. 1, the utility model discloses a take three-way stomach tube joint of valve that contains, including stomach tube interface 1, valve 2, medical hose 4 and multistage universal joint 3, wherein valve 2 is one minute three switching valves. The following is one of the embodiments of the present application.
The valve 2 comprises a housing 201 and a valve core 202; the valve core 202 may be a sphere or a cylinder, and the housing 201 is wrapped outside the valve core 202.
The left end of the shell 201 is connected with the stomach tube interface 1 in a through manner, and a fanned ring-shaped stomach tube adapter cavity 205 is arranged between the stomach tube interface 1 and the valve core 202 in the shell 201; if the valve requires a fully closed position, the fan-shaped central angle of the gastric tube adapter 205 fan ring is less than or equal to 135 degrees.
The other side position of the stomach tube switching cavity 205 in the shell 201, which is opposite to the valve core 202, is provided with three switching tubes 204 which are uniformly distributed at intervals, and a valve core channel 203 for connecting the switching tubes 204 and the stomach tube switching cavity 205 is arranged in the valve core 202; namely, the distribution positions of the three adapter tubes 204 are symmetrical to the stomach tube adapter cavity 205.
Sealing rings are arranged at the sliding connection positions of the stomach tube adapter cavity 205, the adapter tube 204 and the valve core 202, and are used for ensuring the sealing performance of the valve. The three adapter tubes 204 are spaced apart on the outer wall of the valve core 202 by a distance greater than the diameter of the valve core passage 203 to ensure that the three connections are not accessed through the valve core passage 203.
When the two ends of the valve core channel 203 of the valve core 202 are rotated to the positions respectively communicated with the gastric tube adapter cavity 205 and one adapter tube 204, the adapter tube 204 is communicated with the gastric tube.
When one end of the valve core passage 203 of the valve core 202 is rotated to a position between the two adapter tubes 204 and does not communicate with any adapter tube 204, the valve 2 is closed, and the valve core passage 203 of the valve core 202 communicates with the gastric tube.
When the central angle of the gastric tube adapter cavity 205 is smaller than 135 degrees, both ends of the valve core channel 203 of the valve core 202 rotate to the position where the gastric tube adapter cavity 205 is not communicated, and the valve 2 is completely closed. The valve core channel 203 of the valve core 202 is not in communication with the gastric tube.
A middle shaft 206 penetrating through the shell 201 is fixedly arranged at the upper end of the middle part of the valve core 202, and a wrench 207 is fixedly arranged at the upper end of the middle shaft 206; by turning the wrench 207, the valve core 202 is driven to turn, thereby controlling the open/close state of the valve 2. The wrench 207 is provided with a pointer for indicating the valve on state.
The three adapter tubes 204 are respectively connected with the multi-stage universal joint 3 through medical hoses 4. Three multi-stage universal joints 3 are distributed on the other side of the stomach tube interface 1 relative to the valve.
