Description

Technical Field

[0001] The utility model relates to the technical field of triangular valves for petroleum pipelines, in particular to a novel triangular valve for petroleum pipelines. Background Art

[0002] Angle valve is also called triangular valve, angle valve, and angle water valve. This is because the pipeline forms a 90-degree corner shape at the angle valve, so it is called an angle valve, an angle valve, and an angle water valve. The valve body of the angle valve has three ports: water inlet, water volume control port, and water outlet, so it is called a triangular valve. Of course, the current angle valve is constantly improving. Although it still has three ports, there are also angle valves that are not angled. The existing triangular valve needs to be replaced as a whole when it is damaged, and the triangular valve does not have a filtering function. When the triangular valve is installed on an oil pipeline, some impurities contained in the oil can easily block the valve core in the triangular valve, making it unusable and requiring cleaning. The valve head of the existing triangular valve is usually a manual rotary wheel without a locking structure. It is very easy to be turned open or closed by people in the field, causing great economic losses. For this reason, we have proposed a new type of oil pipeline triangular valve to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 , the utility model provides an embodiment: a novel oil pipeline triangular valve, comprising a valve body 1;

[0021] A knob 2 is rotatably mounted on the upper end of the valve body 1, a valve core 3 is rotatably mounted inside the valve body 1, the upper end of the valve core 3 is fixedly connected to the knob 2, a water inlet 4 is arranged at the lower end of the valve body 1, a water outlet 5 is arranged on the right side of the valve body 1, a first connector 6 is threadedly inserted in the water inlet 4, a second connector 7 is threadedly inserted in the water outlet 5, an anti-blocking component is arranged in the first connector 6, the device fixes the valve body 1 to the oil pipeline through the first connector 6 and the second connector 7, the knob 2 and the valve core 3 are rotated to open the valve body 1 to facilitate the flow of oil, and the impurities in the oil are filtered through the anti-blocking component;

[0022] Furthermore, one end of the first connector 6 and the second connector 7 installed in the water inlet 4 and the water outlet 5 and the opposite end are both sleeved with a sealing ring 8, and the sealing ring 8 is made of rubber material. This structure improves the sealing effect of the connection when the first connector 6 and the second connector 7 are connected to the valve body 1 and the oil pipeline through the sealing ring 8.

[0023] Furthermore, the anti-clogging component includes a filter 9, which is installed in the first connecting head 6. A rotating shaft 10 is installed in the valve core 3 through a thread. The lower end of the rotating shaft 10 is inserted in the filter 9. Four groups of scrapers 11 are installed at the bottom of the lower end of the rotating shaft 10. The four groups of scrapers 11 are in contact with the lower side of the filter 9. This structure drives the rotating shaft 10 and the four groups of scrapers 11 to rotate by rotating the knob 2 and the valve core 3, so as to scrape off impurities contaminated on the lower side of the filter 9.

[0024] Furthermore, the four groups of scrapers 11 are all arranged in an inclined shape, and the higher inclined side of the four groups of scrapers 11 fits the lower side of the filter 9. This structure is based on the installation angle of the four groups of scrapers 11, so that the higher side of the four groups of scrapers 11 can scrape off impurities contaminated on the lower side of the filter 9 when rotating.

[0025] Furthermore, a thread groove 12 is opened in the right end of the knob 2, and a thread block 13 is installed in the thread groove 12 through a thread. A fixing plate 14 is installed at the upper end of the valve body 1, and a limiting rod 15 is installed on the right side of the upper end of the fixing plate 14. The right end of the limiting rod 15 is inserted into the opening at the left end of the thread groove 12. This structure rotates the thread block 13 in the thread groove 12 to push the limiting rod 15 out from the left end of the thread groove 12, so that the knob 2 can be rotated to prevent the knob 2 from being rotated by outsiders.

[0026] Furthermore, the right end edge of the limiting rod 15 is arc-shaped, the diameter of the right end of the limiting rod 15 is the same as the inner wall diameter of the thread groove 12, and a hexagonal groove is arranged in the right end of the thread block 13. This structure is convenient for inserting the limiting rod 15 into the thread groove 12 according to the size of the right end of the limiting rod 15 and the thread groove 12, and using a hexagonal wrench inserted into the right end of the thread block 13 to rotate the thread block 13.

[0027] Working principle: When using valve body 1, Figure 2 As shown, the first connector 6 and the second connector 7 are inserted into the water inlet 4 and the water outlet 5 by bolts, the valve body 1 is inserted into the oil pipeline through the lower end of the first connector 6, and the second connector 7 is connected to another set of oil pipelines, and the knob 2 and the valve core 3 are rotated, as shown in FIG. Figure 3 , Figure 4 and Figure 5 As shown, an inner hexagonal wrench is inserted into the right end of the threaded block 13, and the inner hexagonal wrench drives the threaded block 13 to rotate in the threaded groove 12. The threaded block 13 moves to the left to push the right end of the limit rod 15 out of the threaded groove 12, and the knob 2 and the valve core 3 can be rotated. When the knob 2 drives the valve core 3 to rotate and open in the valve body 1, the oil in the oil pipeline flows into the valve body 1 through the filter screen 9 in the first connector 6, and then the oil flows out from the water outlet 5 and the second connector 7. The filter screen 9 filters the impurities in the oil, and the rotation of the knob 2 and the valve core 3 drives the rotating shaft 10 and the four groups of scrapers 11 to rotate. The four groups of scrapers 11 rotate to scrape off the impurities contaminated on the lower side of the filter screen 9, thereby preventing the impurities in the oil from entering the valve body 1 and clogging the valve core 3. The above is the entire working principle of the utility model.
