Referring to fig. 1-3, one embodiment provided by the present invention: a check valve in an ultrahigh pressure chemical medium booster pump comprises an outlet check valve body 1, various elements are arranged in the main body of the check valve, a feed inlet 11 is arranged at the upper side in the outlet check valve body 1, ultrahigh pressure chemical substances are added from the feed inlet 11, a first channel 12 is arranged at the lower side of the feed inlet 11, an air-tight component is arranged in the first channel 12 and is used for preventing the ultrahigh pressure chemical medium from flowing back due to air leakage in the outlet check valve body 1, a sealing seat body 3 is arranged at the top of the left wall and the right wall of the first channel 12, the sealing seat body 3 is annular and can impact the sealing seat body 3 through a steel ball 4 to form a closed environment, the unidirectional property of the check valve can be realized by preventing the high-strength chemical medium from flowing back under strong pressure, the sealing seat body 3 is made of PEEK material, the sealing seat made of the PEEK material has excellent chemical stability and is almost stable to any chemical reagent except concentrated sulfuric acid, even under higher temperature, the one-way valve still can keep good chemical stability, in addition, the one-way valve also has excellent hot water resistance and steam resistance, can be used for a long time in steam of 200 plus 250 ℃, the sealing seat can bear high-frequency impact from the steel ball 4 without deformation and damage due to the super-strong mechanical property and the wear resistance, so that the one-way valve in the booster pump is more durable to use, the valve inner O-ring 2 is arranged between the sealing seat body 3 and the inner wall of the first channel 12, the valve inner O-ring 2 is a rubber sealing ring, the valve inner O-ring 2 is arranged between the sealing seat body 3 and the inner wall of the first channel 12, so that the sealing seat body 3 extrudes the valve inner O-ring 2 when the sealing seat body 3 is impacted by the steel ball 4, the valve inner O-ring 2 is more attached to the sealing seat body 3 and the inner wall of the first channel 12 under extrusion, and the air tightness of the inner part of the outlet one-way valve 1 is enhanced when the one-way valve works, the bottom of the seal seat body 3 is provided with a seal seat gasket 5, when ultrahigh pressure chemical medium enters from the feed port 11, the seal seat body 3 is extruded downwards, the seal seat body 3 is extruded with the seal seat gasket 5, so that the seal seat body 3 and the seal seat gasket 5 are connected more tightly, the ultrahigh pressure chemical medium is prevented from permeating into the one-way valve when passing through the one-way valve, the lower side of the seal seat gasket 5 on the inner wall of the first channel 12 is fixedly connected with a guide seat 6 for guiding the passing direction of the ultrahigh pressure chemical medium and the moving direction of the spring 7 and the steel ball 4, the middle lower part of the guide seat 6 is provided with a second channel 13 for leading the ultrahigh pressure chemical medium to pass through and mounting the spring 7, the steel ball 4 is arranged inside the guide seat 6, after the ultrahigh pressure chemical medium enters the one-way valve, the steel ball 4 is in high pressure to be in contact with the seal seat body 3 upwards to extrude the seal seat body 3, and the function of preventing the chemical medium from flowing back is started, the lower side of the steel ball 4 is provided with a fixedly connected spring 7, chemical media enable the spring 7 to shrink through downwards extruding the steel ball 4, so that the chemical media enter the one-way valve through a gap between the steel ball 4 and the sealing seat body 3, and the other end of the spring 7 is fixedly connected to the bottom of the second channel 13.
The lower side of the interior of the guide seat 6 is provided with a third channel 15 which plays a role in flow guiding, the end surface O-shaped ring 9 is arranged on the outer end surface of the outlet one-way valve body 1, so that the outlet one-way valve body 1 is more tightly connected with a booster pump, the bottom of the guide seat 6 is provided with a retainer ring 8 which has a limiting function for preventing the guide seat 6 from displacing, the bottom of the second channel 13 is provided with a first through hole 14 which is used for guiding chemical media to flow and playing a role in connecting the second channel 13 with the third channel 15, the bottom of the third channel 15 is provided with a second through hole 16 which is used for connecting the third channel 15 with a discharge hole 10, the bottom of the second through hole 16 is provided with a discharge hole 10, the chemical media flow out of the one-way valve through the discharge hole 10, the shapes of the first through hole 14 and the second through hole 16 are funnel-shaped and inverted funnel-shaped respectively, and are used for better connection and drainage.
The working principle is as follows: when an ultrahigh pressure chemical medium passes through the outlet one-way valve body 1, the ultrahigh pressure chemical medium enters the outlet one-way valve body 1 from the feed port 11 and then reaches the first channel 12, the chemical medium extrudes the steel ball 4 downwards, the spring 7 arranged at the bottom of the steel ball 4 contracts under the action of pressure, so that the steel ball 4 moves downwards, the steel ball 4 is separated from the seal seat body 3 to form a gap, the chemical medium enters the guide seat 6 through the gap and then leaves the outlet one-way valve body 1 from the discharge port 10 through the second channel 13 and the third channel 15, after the ultrahigh pressure chemical medium passes through the outlet one-way valve body 1, the air pressure at the discharge port 10 of the outlet one-way valve body 1 is greater than the air pressure at the feed port 11 when the ultrahigh pressure chemical medium passes through, so that the steel ball 4 is pushed upwards to impact the seal seat body 3, so that the seal seat body 3 and the O-shaped ring 2 in the valve extrude the inner wall of the first channel 12, therefore, the sealing performance of the sealing seat body 3 is greatly improved, and the situation that the sealing performance is weakened due to the fact that the steel ball 4 collides with the sealing seat body 3 to form a gap is avoided.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
