DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a multi-directional die-forged refrigeration straight-through valve body provided by the utility model; Figure 2 for Figure 1 A front view of a multi-directional die-forged refrigeration straight-through valve body; Figure 3 for Figure 1 A front sectional view of a valve body No. 1 in the multi-directional die-forged refrigeration straight-through valve body shown; Figure 4 for Figure 1The front view of the lifting column in the multi-directional die-forged refrigeration straight-through valve body shown. The multi-directional die-forged refrigeration straight-through valve body includes a valve body No. 1 and a valve body No. 2. The internal movable sleeve of the valve body No. 2 is connected with a lifting column 3, and the external movable sleeve of the lifting column 3 is connected with a sealing sleeve 4. The top of the valve body No. 2 is threadedly connected with a threaded column 5. The top of the inner cavity of the valve body No. 2 is fixedly connected with a limit column 6, and the external movable sleeve of the limit column 6 is connected with a spring 7. The internal fixed sleeve of the valve body No. 1 is connected with a fixed block 8, and the side of the fixed block 8 is fixedly connected with a sealing sleeve 9. The top of the sealing sleeve 9 is provided with a sealing mechanism 10, the side of the valve body No. 1 is provided with a connecting mechanism 11, and the top of the threaded column 5 is provided with an auxiliary mechanism 12.

[0025] The lifting column 3 is located directly above the closing sleeve 9, and the height of the lifting column 3 is greater than the height of the closing sleeve 9; by setting the lifting column 3, when the valve is used for a long time and causes serious wear inside the lifting column 3, the closing sleeve 9 can fill the gap between the lifting column 3 and the closing sleeve 9, thereby achieving a sealing effect inside the No. 2 valve body 2, thereby avoiding the problem that the lifting column 3 is severely worn when used for a long time, causing the water flow inside the No. 1 valve body 1 to seep out through the internal gap of the No. 2 valve body 2 and be discharged through the top of the No. 2 valve body 2, thereby improving the internal sealing effect of the No. 2 valve body 2 when used for a long time, that is, improving the stability of the valve when used for a long time.

[0026] The threaded column 5 and the first valve body 1 are perpendicular to each other, and one end of the threaded column 5 is movably sleeved on the top of the lifting column 3; by setting the threaded column 5, when the valve is closed, the threaded column 5 is rotated so that the threaded column 5 can drive the lifting column 3 to be sleeved inside the closing sleeve 9, thereby achieving the closing effect of the closing sleeve 9, that is, achieving the closing effect of the valve.

[0027] One end of the limiting column 6 is movably sleeved on the top of the lifting column 3, and there are two limiting columns 6. By setting the limiting column 6, when the position of the lifting column 3 is adjusted, the limiting column 6 can move up and down inside the lifting column 3. At this time, the limiting column 6 can limit the lifting column 3 moving up and down, thereby avoiding the problem of the lifting column 3 being driven to rotate when the threaded column 5 rotates, thereby improving the stability of the lifting column 3 when it is lifted or lowered.

[0028] There are two springs 7, and the two springs 7 are symmetrically distributed with the threaded column 5 as the axis of symmetry; by setting the spring 7, when the position of the lifting column 3 is adjusted, the spring 7 can squeeze the threaded column 5 through the lifting column 3, so that the external thread of the threaded column 5 can fit tightly with the internal thread of the No. 2 valve body 2, thereby avoiding the problem of shaking of the threaded column 5 and further improving the stability of the threaded column 5.

[0029] The sealing mechanism 10 includes a limiting groove 101, which is opened at the top of the inner wall of the closing sleeve 9, and a No. 1 sealing ring 102 is fixedly sleeved inside the limiting groove 101; by setting the sealing mechanism 10, when the closing sleeve 9 is closed, the threaded column 5 is rotated so that the threaded column 5 can drive the lifting column 3 to be tightly pressed on the top of the No. 1 sealing ring 102, and at this time the No. 1 sealing ring 102 can fill the gap between the closing sleeve 9 and the lifting column 3, thereby improving the sealing performance of the closing sleeve 9 after closing.

[0030] The connecting mechanism 11 includes a bolt 111, which is threadedly sleeved on the side of the No. 1 valve body 1, and a No. 2 sealing ring 112 is fixedly sleeved on the side of the No. 1 valve body 1. By setting the connecting mechanism 11, when the valve is installed and connected, the pipeline is sleeved inside the No. 1 valve body 1, and at this time, the bolt 111 is passed through the pipeline and threadedly sleeved on the side of the No. 1 valve body 1, so that one end of the pipeline can be squeezed and fixed inside the No. 1 valve body 1, thereby achieving the installation and connection effect of the valve.

[0031] The auxiliary mechanism 12 includes a turntable 121, which is fixedly connected to the top of the threaded column 5. A protective column 122 is fixedly connected to the front of the turntable 121, and the material of the protective column 122 is rubber material. By setting the auxiliary mechanism 12, when the valve is switched, the turntable 121 is rotated so that the turntable 121 can drive the threaded column 5 to rotate, thereby avoiding the problem of the user's hand being hurt by the hard surface of the threaded column 5, thereby improving the convenience of opening and closing the valve.

[0032] The working principle of the multi-directional die forged refrigeration straight-through valve body provided by the utility model is as follows:

[0033] Step 1: First, when the valve is used for a long time and causes serious wear inside the lifting column 3, the closing sleeve 9 can fill the gap between the lifting column 3 and the closing sleeve 9, thereby achieving a sealing effect inside the No. 2 valve body 2, so as to avoid the problem that the lifting column 3 is seriously worn out during long-term use, causing the water inside the No. 1 valve body 1 to seep out through the internal gap of the No. 2 valve body 2 and be discharged through the top of the No. 2 valve body 2, thereby improving the internal sealing effect of the No. 2 valve body 2 when used for a long time, that is, improving the stability of the valve when used for a long time. When closing the valve, rotate the threaded column 5 so that the threaded column 5 can drive the lifting column 3 to be sleeved inside the closing sleeve 9. Thus, the sealing effect of the sealing sleeve 9 is achieved, that is, the closing effect of the valve is achieved. When the position of the lifting column 3 is adjusted, the limit column 6 can move up and down inside the lifting column 3. At this time, the limit column 6 can limit the lifting column 3 that moves up and down, so as to avoid the problem that the lifting column 3 is driven to rotate when the threaded column 5 rotates, thereby improving the stability of the lifting column 3 when it is lifted. When the position of the lifting column 3 is adjusted, the spring 7 can squeeze the threaded column 5 through the lifting column 3, so that the external thread of the threaded column 5 can be closely fitted with the internal thread of the second valve body 2, thereby avoiding the problem of shaking of the threaded column 5, thereby improving the stability of the threaded column 5;

[0034] Step 2: When closing the closing sleeve 9, rotate the threaded column 5 so that the threaded column 5 can drive the lifting column 3 to be tightly squeezed on the top of the No. 1 sealing ring 102. At this time, the No. 1 sealing ring 102 can fill the gap between the closing sleeve 9 and the lifting column 3, thereby improving the sealing performance of the closing sleeve 9 after closing. When installing and connecting the valve, the pipe is sleeved inside the No. 1 valve body 1. At this time, the bolt 111 is passed through the pipe thread sleeve and sleeved on the side of the No. 1 valve body 1, so that one end of the pipe can be squeezed and fixed inside the No. 1 valve body 1, thereby achieving the installation and connection effect of the valve. When opening and closing the valve, rotate the turntable 121 so that the turntable 121 can drive the threaded column 5 to rotate, thereby avoiding the problem of the user's hand being injured due to the hard surface of the threaded column 5, thereby improving the convenience of opening and closing the valve.

[0035] Compared with the related art, the multi-directional die-forged refrigeration straight-through valve body provided by the utility model has the following beneficial effects:

[0036] By setting the lifting column 3, when the valve is used for a long time and the interior of the lifting column 3 is seriously worn, the closing sleeve 9 can fill the gap between the lifting column 3 and the closing sleeve 9, thereby achieving a sealing effect inside the No. 2 valve body 2, thereby avoiding the problem that the lifting column 3 is seriously worn when used for a long time, causing the water flow inside the No. 1 valve body 1 to seep out through the internal gap of the No. 2 valve body 2 and be discharged through the top of the No. 2 valve body 2, thereby improving the internal sealing effect of the No. 2 valve body 2 when used for a long time, that is, improving the stability of the valve when used for a long time.
