[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Embodiment 1, as Figures 1 to 6 As shown, this embodiment 1 provides an integrated chemical pressure valve, including: a pipeline 1 and a pressure sensor 2; the pipeline 1 is suitable for liquid to flow through; the pressure sensor 2 is arranged on the pipeline 1; the liquid flowing through the pipeline 1 is suitable for contacting the pressure sensor 2, and the pressure of the liquid flowing through the pipeline 1 is detected by the pressure sensor 2; it is achieved that when the liquid pressure in the pipeline 1 is detected, excess air can be emptied, so as to facilitate accurate detection of the liquid pressure.

[0053] In this embodiment, one end of the pipeline 1 is a water inlet 11, and the other end is a water outlet 12; a pressure detection port 13 is connected to the pipeline 1, and the pressure detection port 13 is communicated with the pipeline 1; the pressure sensor 2 is arranged on the pressure detection port 13; liquid can enter the pipeline 1 through the water inlet 11 and flow out of the pipeline 1 through the water outlet 12. In the process of flowing through the pipeline 1, the liquid flows to the pressure sensor 2 through the pressure detection port 13, and the pressure of the liquid is detected by the pressure sensor 2.

[0054] In this embodiment, a filter 14 is provided in the pipeline 1; the filter 14 is arranged close to the liquid outlet; the connection position between the pressure detection port 13 and the pipeline 1 is located between the water inlet 11 and the filter 14; the filter 14 can filter impurities in the liquid before the liquid flows out of the water outlet 12.

[0055] In this embodiment, a blocking mechanism 3 is provided in the pipeline 1; the blocking mechanism 3 is arranged between the filter 14 and the water inlet 11; the position where the pressure detection port 13 is connected to the pipeline 1 is located between the water inlet 11 and the blocking mechanism 3; the blocking mechanism 3 is suitable for controlling the opening and closing of the pipeline 1; when the liquid starts to flow into the pipeline 1, the pipeline 1 is first closed by the blocking mechanism 3, so that all the liquid flows to the pressure detection port 13, and all the air and other liquids that may remain in the pressure detection port 13 are discharged, so that when the pipeline 1 is opened, there is no air or other liquid between the liquid and the pressure sensor 2, and the pressure of the liquid in the pipeline 1 can be accurately detected.

[0056] In this embodiment, the blocking mechanism 3 includes: a blocking component and a connecting pipe 31; the blocking component is arranged in the pipeline 1; one end of the connecting pipe 31 is connected to the blocking component, and the other end of the connecting pipe 31 is connected to the pressure detection port 13, and the connection position is close to the pipe mouth position of the pressure detection port 13, so as to facilitate the exhaustion of air and / or other liquids that may exist in the pressure detection port 13; a liquid outlet is provided on the blocking component, and the liquid outlet is connected to the connecting pipe 31. When the blocking component blocks and closes the pipeline 1, the liquid enters the pipeline through the water inlet 11 and all flows to the pressure detection port 13, and the air and / or other liquids that may exist in the pressure detection port 13 (other liquids may be liquids that have flowed through the pipeline 1 before, and the composition of the liquid is different from that of the current liquid) are pushed into the connecting pipe 31, enter the pipeline 1 through the connecting pipe 31 and are discharged from the water outlet 12, so that the air and / or other liquids that may exist in the pressure detection port 13 can be exhausted, so as to facilitate the subsequent accurate detection of the pressure in the pipeline 1.

[0057] In this embodiment, a real-time mode of the blocking mechanism 3 is that the blocking member includes: a ring body 32; the ring body 32 is arranged in the pipeline 1; the ring body 32 is suitable for partially moving out of the pipeline 1; a baffle 33 is arranged in the ring body 32; a liquid outlet hole is opened on the inner wall of the ring body 32, and the liquid outlet hole is connected to the connecting pipe 31; the liquid outlet hole is located between the baffle 33 and the filter 14; the ring body 32 can move in the pipeline 1, and a notch can be opened on the side wall of the pipeline 1 to facilitate the ring body 32 to partially move out of the pipeline 1 When the ring body 32 moves, it drives the baffle 33 to move; when it is necessary to drain the air and / or other liquids that may exist in the pressure detection port 13, the ring body 32 can be manually inserted into the pipeline 1 so that the outer wall of the ring body 32 contacts the inner wall of the pipeline 1. At this time, the baffle 33 can completely block the pipeline 1, so that the liquid flows to the pressure detection port 13, and the air and / or other liquids that may exist in the pressure detection port 13 are pushed into the connecting pipe 31, and then discharged from the liquid outlet hole, and then can be discharged from the pipeline 1. After the liquid flows for a certain period of time, for example For example, 10 seconds, at this time, it can be determined that the air and / or other liquids that may exist in the pressure detection port 13 have been exhausted, and at this time, the ring body 32 can be partially pulled out of the pipeline 1 manually, and the pipeline 1 can be opened. The liquid flows through the pipeline 1 normally, and the pressure of the liquid is detected by the pressure sensor 2. At this time, part of the ring body 32 is located at the gap of the pipeline 1 to block the gap to prevent the pipeline 1 from leaking. A sealing ring can be set on the gap to achieve the sealing of the ring body 32 and the gap. For example, when the ring body 32 is inserted into the pipeline 1, the sealing ring can contact the end face of the ring body 32 to seal. When the ring body 32 is partially pulled out of the pipeline 1, the sealing ring can contact the baffle 33 to seal. The sealing ring is made of elastic material and can be deformed, which is convenient for sealing in various situations. When the ring body 32 is partially removed from the pipeline 1, the liquid outlet can be located at the gap (that is, when the ring body 32 is located in the pipeline 1, the liquid outlet is located away from the gap), and the liquid outlet is blocked by the gap. At this time, the outer wall of the ring body 32 is as flush as possible with the inner wall of the pipeline 1 to avoid changing the inner diameter of the pipeline 1. When cleaning, the ring body 32 can be completely pulled out of the pipeline 1 to remove the scraped impurities.

[0058] In this embodiment, a scraper ring 34 is provided on the end face of the ring body 32 close to the filter screen 14, and the scraper ring 34 is in contact with the filter screen 14; when the ring body 32 is pulled out, the contact between the scraper ring 34 and the filter screen 14 can scrape off impurities on the filter screen 14 to prevent the filter screen 14 from being blocked.

[0059] In this embodiment, another real-time mode of the blocking mechanism 3 is that the blocking member includes: a ring body 32; the ring body 32 is arranged in the pipeline 1; a baffle 33 is rotatably arranged on the inner wall of the ring body 32, and the baffle 33 is connected to the inner wall of the ring body 32 through a turntable 35; a plurality of liquid outlets are opened on the ring body 32, and the liquid outlets are connected to the connecting pipe 31; the liquid outlets are suitable for being blocked by the turntable 35 when the turntable 35 drives the baffle 33 to open the pipeline 1; the turntable 35 can be a rectangular parallelepiped, and the turntable 35 can be driven by a motor to rotate to drive the baffle 33 to rotate, and when it is necessary to exhaust the air and / or other liquids that may exist in the pressure detection port 13 When the turntable 35 is in a vertical state, the baffle 33 blocks the pipeline 1, allowing the liquid to flow to the pressure detection port 13, pushing the air and / or other liquids that may exist in the pressure detection port 13 into the connecting pipe 31, and then discharged from the liquid outlet, and then discharged from the pipeline 1. After the liquid has flowed for a certain period of time, for example 10 seconds, it can be determined that the air and / or other liquids that may exist in the pressure detection port 13 have been exhausted. At this time, the turntable 35 can be driven by the motor to rotate to the horizontal state, and the baffle 33 also rotates accordingly to open the pipeline 1. When the turntable 35 is in a vertical state, the liquid outlet is opened, and when the turntable 35 is in a horizontal state, the liquid outlet can be blocked.

[0060] Embodiment 2, based on Embodiment 1, this Embodiment 2 further provides a working method adopted by the integrated chemical pressure valve in Embodiment 1, including: when the liquid flows through the pipeline 1, the liquid flows to the pressure sensor 2, and the pressure of the liquid in the pipeline 1 is detected by the pressure sensor 2.
