Description

Technical Field

[0001] The invention relates to the technical field of high-pressure valve castings, in particular to a high-pressure valve body casting. Background Art

[0002] Common high-pressure valves are divided into two-way valves, three-way valves and four-way valves, among which three-way valves are more common. The three-way valve consists of a valve body and three flange ports connected to the water source. In order to improve the production efficiency of the three-way valve, the common production process of the three-way valve is casting. During casting, high-temperature molten metal is added to the mold cavity, and it is quickly formed in the mold cavity under the intervention of the cooling medium. The mold is opened and the casting is taken out. The connection hole is drilled on the flange port to obtain the final high-pressure valve.

[0003] Since the three valve ports of the three-way valve are distributed in a T-shape, an angle is formed between each valve port and the valve body. When the three-way valve is connected to a high-pressure pipeline for use, a large load will be borne between the pipeline and the valve port. In particular, when the three-way valve is in a suspended environment, a high load-bearing capacity is required to prevent deformation of each port. Since the high-pressure valve is connected to a high-pressure pipeline, water seepage may occur at each flange interface during actual use. This is not easy to observe in advance with the naked eye, and there is a safety hazard. Summary of the invention

DETAILED DESCRIPTION

[0030] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0031] In one embodiment, if Figure 1-Figure 7 As shown:

[0032] This embodiment provides a high-pressure valve body casting, including a three-way valve body 1, a first port 2 with an opening facing left is provided at the left end of the valve body 1, a second port 3 with an opening facing right is provided at the right end, a third port 4 with an opening facing upward is provided at the top, a reinforcing rib 5 is provided on the valve body 1, a first molding flange 9 is provided at the end of the first port 2, a second molding flange 10 is provided at the end of the second port 3, a third molding flange 11 is provided at the end of the third port 4, and the third port 4 is close to the third molding flange 11 and away from the first molding flange 9;

[0033] The reinforcing rib 5 includes a first rib 6, a second rib 7 and a third rib 8. The first rib 6 is cast on the bottom side of the valve body 1 along the bottom contour of the valve body 1. The left end of the first rib 6 extends to the inner surface of the first molding flange 9, and the right end of the first rib 6 extends to the inner surface of the second passage 3. The second rib 7 includes a first chamfered portion 71 and a second chamfered portion 72. The first chamfered portion 71 is molded to the inner surface of the first molding flange 9, and the second chamfered portion 72 is molded to the inner surface of the second molding flange 10.

[0034] The first rib 6 is S-shaped, so that the first rib 6 is provided with a hump section 12 protruding upward and a steep section 13 concave downward from right to left;

[0035] The third rib 8 is divided into a first portion 81 and a second portion 82. The first portion 81 is formed to the inner surface of the second molding flange 10 in the form of a right-downward rounded transition; the second portion 82 is formed between the hump section 12 and the steep section 13 in the form of a downward rounded transition;

[0036] An S-shaped cavity 15 is opened outside the reinforcing rib 5 along the S-shaped contour of the first rib 6, and a detection port is provided on the valve body 1, which includes a first detection port 16 opened on the cavity 15 and located at the peak of the steep section 13, and the opening of the first detection port 16 faces downward.

[0037] When the valve body 1 is connected to a three-way pipeline using the first molded flange 9, the second molded flange 10 and the third molded flange 11, the load acting on the valve body 1 on the three-way pipeline is transmitted to the reinforcing rib 5 at the bottom. The reinforcing rib 5 can prevent the valve body 1 from bearing the loads in the above three directions and thus increase its strength, especially preventing the first port 2 and the second port 3 from bending and deformation.

[0038] In addition, a first chamfered portion 71 is provided at the connection position between the first molded flange 9 and the first channel 2, and the first chamfered portion 71 is used to prevent stress concentration at the connection position between the first molded flange 9 and the first channel 2, and can further prevent the first channel 2 from being deformed. A second chamfered portion 72 is provided at the connection position between the second molded flange 10 and the second channel 3, and the second chamfered portion 72 is used to prevent stress concentration at the connection position between the second molded flange 10 and the second channel 3, and can also further prevent the second channel 3 from being deformed.

[0039] In addition, an arc-shaped second portion 82 is provided at the connection portion between the first channel 2 and the third channel 4, and the arc-shaped second portion 82 is used to prevent stress concentration at the connection portion between the first channel 2 and the third channel 4, thereby further preventing the first channel 2 from being deformed. An arc-shaped first portion 81 is provided at the connection portion between the second channel 3 and the third channel 4, and the arc-shaped first portion 81 is used to prevent stress concentration at the connection portion between the second channel 3 and the third channel 4, thereby further preventing the second channel 3 from being deformed.

[0040] In addition, when the valve body 1 is used on a pipeline through the above-mentioned tee connection, if water seeps from the pipe opening connected to a certain flange, the water will leak from the flange interface to the valve body 1. For example, when water seeps out from the pipe opening connected to the third molded flange 11, the water will flow along the fillet 18 of the third molded flange 11 to the first part 81 and the second part 82 of the third rib 8, and then flow along the arc-shaped outer wall of the first part 81 and the second part 82. Part of the water flows to the second chamfered part 72 on the right side after being guided by the first part 81, and then flows from the second chamfered part 72 to the pipe wall of the second passage 3, and then flows from the pipe wall of the second passage 3 to the right area of ​​the first rib 6, that is, flows into the right area of ​​the cavity 15, and flows from the hump section 12 along the cavity 15 to the steep The water flows through the steep section 13 and then drips downward rapidly through the first detection port 16 on the steep section 13 in a steep flow manner; another part of the water flows directly downward to the hump section 12 of the cavity 15 through the second part 82 of the third rib 8, and then flows into the steep section 13 from the hump section 12, and finally converges with the water from the first part 81 and is discharged downward through the first detection port 16. When water seepage occurs, the water flow direction of the first detection port 16 is observed, and it is intuitively known that the third channel 4 has a water leakage problem. Since the water leakage of the first detection port 16 comes from the first part 81 and the second part 82 of the third rib 8 that converge in large quantities, and finally is quickly released through the steep structure of the cavity 15, it is uniformly and quickly discharged from the first detection port 16. Even if the amount of water is small, detection can be carried out by using a concentrated water flow method.

[0041] In addition, an upper fillet 18 is provided on the circumference of the third molded flange 11, the top edge of the fillet 18 is connected to the top surface of the third molded flange 11, and the bottom edge of the fillet 18 is transitionally connected to the top fillet portion of the first portion 81. The top surface of the third molded flange 11 is an inclined surface, and the inclination direction gradually inclines downward toward the fillet 18. When water seeps from the pipe mouth connected to the third molded flange 11, the water can easily flow through the top inclined surface of the third molded flange 11 to the surrounding fillet 18, and then be drained downward from the fillet 18 to the arc-shaped first portion 81 and the arc-shaped second portion 82, and finally flow into the cavity 15.

[0042] In addition, a secondary cavity 22 is formed on the left end of the first rib 6. The left end of the secondary cavity 22 is close to the first molding flange 9. The right end of the secondary cavity 22 communicates with the left side of the cavity 15 through the bottom side of the notch 19. The first molding flange 9 and the top of the second molding flange 10 are provided with a notch 27 that communicates left and right. In the actual pipeline, the pipe opening connected to the first molding flange 9 may also leak water outward. Figure 2As shown, a notch 27 is also provided on the first forming flange 9, and the seeping water flows downward along the tube wall of the first passage 2 or the first chamfered portion 71 to the auxiliary cavity 22 on the left end of the first rib 6, and is gathered to the right from the auxiliary cavity 22 into the cavity 15, and can also enter the steep section 13 of the cavity 15, and finally discharged downward through the first detection port 16. Even if the amount of water is small, detection can be carried out by using a concentrated water flow method; similarly, a notch 27 is also provided on the second forming flange 10 on the right side. When the pipe opening connected to the second forming flange 10 may leak water outward, the water flows along the tube wall of the second passage 3 or the second chamfered portion 72 to the cavity 15, and can also enter the steep section 13 of the cavity 15, and finally discharged downward through the first detection port 16. Even if the amount of water is small, detection can be carried out by using a concentrated water flow method.

[0043] like Figure 3 As shown, in another embodiment, the detection port also includes a second detection port 17 formed at the connection between the first passage 2 and the third passage 4, the end of the steep section 13 is inclined upward to connect to the second detection port 17, the other end of the second detection port 17 passes through the first passage 2, and passes through the tubular cavity of the first passage 2 to the outside of the top wall; a notch 19 is formed on the steep section 13 of the first rib 6, the notch 19 is close to the second detection port 17, the notch 19 is perpendicular to the width direction of the steep section 13, a carrier plate 20 is fixed in the notch 19, a through hole 21 is opened on the carrier plate 20, the carrier plate 20 is parallel to the bottom side of the second detection port 17, and the through hole 21 and the second detection port 17 are on the same straight line. A detection assembly is installed on the carrier 20, and the detection assembly includes a detection rod 23 that is passed through the through hole 21 on the carrier 20, and a float 24 is installed at the bottom end of the detection rod 23. The float 24 enters the cavity 15, and the top end of the detection rod 23 extends into the second detection port 17 and is installed with a detection seat 25. The detection seat 25 is a colorful plastic part. A spring 26 is connected between the bottom end of the detection seat 25 and the carrier 20, and the spring 26 is sleeved on the detection rod 23. No matter the moisture in the cavity 15 comes from the first molded flange 9, the second molded flange 10, or even the second molded flange 10, they will all enter the cavity 15. As the moisture in the cavity 15 increases, in addition to part of the moisture being discharged downward from the first detection port 16, there is too much moisture in the cavity 15, causing the float 24 to float upward along the left inclined portion of the cavity 15, and the float 24 pushes the detection rod 23 upward, so that the detection seat 25 is exposed from the second detection port 17 at the top of the first pass 2. Since the float 24 needs a buoyancy greater than the supporting force of the spring 26 when floating upward along the left inclined portion of the cavity 15, the requirement for the buoyancy is relatively high, and the size of the buoyancy is determined by the amount of water seepage into the left inclined portion of the cavity 15. Therefore, once the detection seat 25 is exposed from the second detection port 17, it proves that a certain pipe opening or multiple pipe openings of the three-way valve are seriously leaking and need to be repaired or replaced.

[0044] like Figure 7 As shown, the cross-sectional shape of the cavity 15 is an arc, the cross-sectional shape of the auxiliary cavity 22 is an arc, and the outside of the first rib 6 is a plane. During actual assembly, a baffle will be welded on the lower part of the plane. The shape of the baffle is also S-shaped, and its two ends are close to the inner surfaces of the first molded flange 9 and the second molded flange 10. The baffle is used to cover the seepage in the cavity 15, and a part of the water is discharged downward through the first detection port 16, realizing the first detection of the seepage. When the water flow is large, another part of the water rises to the left inclined part of the cavity 15. As the water level gradually rises as it flows to the left, the float 24 pushes the detection rod 23, and the detection rod 23 pushes the detection seat 25 to be exposed upward from the second detection port 17, realizing the second detection of the seepage.

[0045] like Figure 3 , Figure 4 As described, the valve body 1 is composed of two symmetrical parts, which are formed separately during casting. When the blank three-way valve is made, the two parts of the valve body 1 are butted front to back and then welded together. The reinforcing ribs 5 are symmetrically arranged on the front and back parts of the valve body 1, the first detection port 16 and the second detection port 17 are symmetrically arranged front to back, and the cavity 15 is symmetrically arranged front to back. The two symmetrical cavities 15 are both provided with notches 19. As shown, the first detection port 16 on the front side is arranged on the left, and the first detection port 16 on the rear side is arranged on the right. The three-way valve realizes the first water seepage detection through the two first detection ports 16 on the front and back, and realizes the second water seepage detection through the second detection port 17. The detection components are also located in the front and back, which is convenient for human observation from the front and back perspectives.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
