Description

Technical Field

[0001] The present invention relates to the technical field of control valves, and particularly to a new type of 175 MPa ultra-high pressure valve. Background Technique

[0002] An ultra-high pressure valve refers to a valve with a working pressure equal to or higher than 98.1 MPa, generally with a nominal diameter range of 3 - 40 mm and an operating temperature ≤ 300 °C. In terms of structure, the ultra-high pressure valve adopts a conical surface seal to improve the sealing performance and reduce the force on the valve stem; it adopts a rising stem to prevent the sealing surface from being scratched; and it uses a valve stem sealing structure combining fluoroplastics molded packing and metal. High-pressure valves have been widely used in fields such as superhard material manufacturing, chemical industry, petrochemical industry, processing technology, isostatic pressing, ultra-high static pressure extrusion, powder metallurgy, metal forming, and geophysical and geological research. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. The closing member is a disc-shaped valve plate that rotates around its own axis within the valve body to achieve the purpose of opening and closing or regulating.

[0003] The existing new type of 175 MPa ultra-high pressure valve does not have an anti-reversal function. Once the pressure inside the high-pressure valve is overloaded or the fastening components become loose after long-term use, the tightly closed valve of the high-pressure valve will be pushed by the pressure and reverse rotation will occur. At this time, if the high-pressure valve is not fixed again, there will be a risk of leakage of the controlled medium and fluid, which is not convenient for people to use. Summary of the Invention

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the embodiments of the present invention provide a technical solution: a novel 175 MPa ultra-high pressure valve, including a valve body 1, a high-pressure chamber 2 and an adjusting chamber 3. The high-pressure chamber 2 and the adjusting chamber 3 are respectively arranged on both sides of the inner cavity of the valve body 1. The middle part of the left side of the inner cavity of the high-pressure chamber 2 is penetrated by an air inlet 4. The right side of the air inlet 4 and on the left side of the inner cavity of the high-pressure chamber 2 is fixedly connected with a thread. The middle part of the right side of the valve body 1 is penetrated by a limiting bolt 5. The left end of the limiting bolt 5 sequentially penetrates the valve body 1, the adjusting chamber 3 and the high-pressure chamber 2 and extends to the inner cavity of the high-pressure chamber 2. An exhaust air duct 6 is arranged on the surface of the left side of the limiting bolt 5. And the top and bottom of the left side of the inner cavity of the high-pressure chamber 2 are both fixedly connected with sliding parts 7. The surface of the sliding part 7 is slidably connected with a pushing cylinder 8. And the pushing cylinder 8 is threadedly connected with a limiting rod 9. The right end of the limiting rod 9 sequentially penetrates the high-pressure chamber 2, the adjusting chamber 3 and the valve body 1 and extends to the outside of the valve body 1. The right end of the limiting rod 9 is fixedly connected with a limiting gear 10. One side of the bottom of the inner cavity of the high-pressure chamber 2 on the surface of the valve body 1 is penetrated by an exhaust pipe 18. The fastening component of the high-pressure valve is secondarily limited to prevent a series of problems such as metal fatigue during long-term operation in a high-pressure environment, resulting in loosening of the sealing component. The sealing performance of the ultra-high pressure valve is stronger, and it will not easily fall off. Even if the pressure of the transported substance is extremely high, there is no need to worry about the reverse rotation of the bolts of the ultra-high pressure valve caused by pressure overload.

[0026] In the present invention, the right end of the limiting bolt 5 is fixedly connected with an adjusting gear 11, and the middle part of the right side of the adjusting gear 11 is fixedly connected with a protecting plate 12.

[0027] In the present invention, the tooth pattern on the left side of the surface of the limit bolt 5 and the tooth pattern on the left side of the surface of the limit rod 9 are opposite threads, and the adjusting gear 11 at the right end of the limit bolt 5 and the limit gear 10 at the right end of the limit rod 9 are adapted to each other, making the ultra-high pressure valve more intelligent in controlling the conveying medium, and can perform intelligent conveying according to demand, and adjust the overall conveying speed and conveying flow according to the needs of the user, making the overall ultra-high pressure valve more intelligent, thereby making the use effect better.

[0028] In the present invention, support plates 13 are fixedly connected between the two sides of the inner cavity of the adjustment cavity 3 and at the top and bottom of the limiting bolts 5, and fixing plates 14 penetrate the two sides of the surface of the support plate 13.

[0029] In the present invention, a side of the fixing plate 14 away from the supporting plate 13 penetrates the valve body 1 and extends to the outside of the valve body 1 , and a pushing plate 15 is fixedly connected to one side of the fixing plate 14 and located outside the valve body 1 .

[0030] In the present invention, a fastening bolt 16 is fixedly connected to the middle of the surface of the push plate 15 , and one end of the fastening bolt 16 away from the push plate 15 is threadedly connected to the surface of the valve body 1 .

[0031] In the present invention, an arc-shaped limiting plate 17 adapted to the limiting bolt 5 is fixedly connected to one end of the fixing plate 14 close to the limiting bolt 5 .

[0032] During use, first twist the protective plate 12 to make the limit bolt 5 fit the shape inside the high-pressure chamber 2. Then seal the air inlet 4. If complete sealing is required, twist the limit bolt 5 to the bottom of its stroke. If the flow rate needs to be adjusted, turn the outlet end of the exhaust air duct 6 to the outside. When the limit bolt 5 is turned, the adjusting gear 11 will contact the limit gear 10 and then engage, which will drive the limit gear 10 to rotate, thus turning the limit rod 9. Since the tooth pattern on the limit rod 9 in the push cylinder 8 is opposite to that of the limit bolt 5, when the limit bolt 5 is turned to the left, the limit rod 9 will extend outward. Eventually, the limit gear 10 and the adjusting gear 11 will be positioned on the same horizontal line. Being on the same horizontal line means that the exhaust air duct 6 can just circulate the medium. Continuing to turn until they are not on the same horizontal plane means complete closure. After positioning, pull the limit gear 10 to the right to separate it from the adjusting gear 11, then tighten the limit rod 9 and the push cylinder 8, and then push the limit gear 10 back to complete the fixation. When the pressure is too high and the limit bolt 5 is pushed to reverse, it will push the limit gear 10 and cause the bottom limit rod 9 to rotate against the inner wall of the push cylinder 8. However, the screwing stroke between the push cylinder 8 and the limit rod 9 has reached the top, and further screwing is impossible, thus fixing the limit bolt 5. For secondary fixation, the fastening bolt 16 can be turned to screw it into the valve body 1 to apply a thrust to the push plate 15, so that the push plate pushes the arc-shaped limit plate 17 through the fixing plate 14 to fit the limit bolt 5 to form a fixation.
