Description

Technical Field

[0001] This utility model belongs to the field of valve box technology, specifically relating to a large industrial slurry pump valve box. Background Technology

[0002] Mud pumps are mainly used in drilling, cementing, and well workover operations in oil fields and other industrial and mining enterprises. They are mechanical devices used to transport media such as mud, clay mortar, and grout into the borehole during the drilling process. Existing piston-type single-acting mud pumps complete one mud intake and discharge action in one cycle of piston reciprocating motion. That is, the power unit drives the pump crankshaft to rotate, and the crankshaft drives the piston to reciprocate within the cylinder liner through the crosshead. Under the alternating action of the intake valve and discharge valve, the purpose of intake and discharge of mud is achieved.

[0003] Currently, in oil drilling applications, the valve box is one of the key components of a mud pump. The lifespan of the valve box directly affects the overall quality of the mud pump. The critical part affecting the valve box's lifespan is the positioning cone surface where the valve seat is mounted. Due to frequent impacts from the valve body, this area often collapses during use, rendering the entire valve box unusable. A short valve box lifespan necessitates frequent replacements, which not only wastes time and reduces work efficiency but also increases production costs. Utility Model Content

[0029] The first conical surface 14 is located directly below the interface 11, and a first reinforcing hard layer 141 is uniformly provided on the first conical surface 14;

[0030] The valve seat 2 is fixedly disposed on the first reinforced hard layer 141;

[0031] The second conical surface 15 is located above the water inlet 12, and a second reinforcing hard layer 151 is uniformly provided on the second conical surface 15;

[0032] The third conical surface 16 is located to the right of the outlet 13, and a third reinforcing hard layer 161 is uniformly provided on the third conical surface 16.

[0033] In this embodiment, a first reinforcing hard layer 141, a second reinforcing hard layer 151, and a third reinforcing hard layer 161 are respectively provided on the first conical surface 14, the second conical surface 15, and the third conical surface 16. The first reinforcing hard layer 141 can protect the first conical surface 14 and prevent the first conical surface 14 from collapsing during use. The second reinforcing hard layer 151 and the third reinforcing hard layer 161 can prevent the inlet pipe 3 and the outlet pipe from directly contacting the second conical surface 15 and the third conical surface 16, thus protecting the second conical surface 15 and the third conical surface 16.

[0034] In this embodiment, the first reinforcing hard layer 141, the second reinforcing hard layer 151, and the third reinforcing hard layer 161 can be made of ceramic layers, diamond layers, etc.

[0035] Please see Figure 1 The upper end of the valve box body 1 is provided with a first flange face 161, the lower end of the valve box body 1 is provided with a second flange face 18, and the left end of the valve box body 1 is provided with a third flange face 19.

[0036] The first flange face 161, the second flange face 18, and the third flange face 19 are provided for connection with the corresponding flanges.

[0037] Please see Figure 1 The first flange face 161 has a first groove 171 on its inner side, the second flange face 18 has a second groove on its inner side, and the third flange face 19 has a third groove on its inner side. A first sealing ring 172, a second sealing ring, and a third sealing ring are correspondingly provided in the first groove 171, the second groove, and the third groove.

[0038] When the first flange face 161, the second flange face 18, and the third flange face 19 are connected to the corresponding flanges, the flanges can press the corresponding sealing rings to achieve a seal at the connection.

[0039] Please see Figure 1It also includes a water inlet pipe 3, which includes a first pipe body 31, a first connector 32 and a first flange 33. The first connector 32 is fixedly disposed at the end of the first pipe body 31, and the first flange 33 is fixedly disposed on the first connector 32. The first flange 33 is connected to the second flange face 18 and presses against the second sealing ring. The first connector 32 extends into the water inlet 12.

[0040] The second sealing ring can be tightened by connecting the first flange 33 to the second flange face 18. The first connector 32 extends into the inlet 12. When the mud pump is working, the first connector 32 will vibrate and come into contact with the second conical surface 15. The second reinforcing hard layer 151 can protect the second conical surface 15.

[0041] Please see Figure 1 A first shock-absorbing pad 34 is provided between the first joint 32 and the first flange 33.

[0042] The first shock-absorbing pad 34 is fitted onto the first connector 32. Its outer diameter is greater than or equal to the upper diameter of the first connector 32, so that after the first connector 32 is inserted into the water inlet 12, the first shock-absorbing pad 34 contacts the water inlet 12, thereby achieving a shock-absorbing effect.

[0043] Please see Figure 1 The outer side wall of the first shock-absorbing pad 34 is provided with a first anti-slip texture.

[0044] The first anti-slip texture is designed to increase the anti-slip effect after the first damping pad 34 is in contact with the water inlet 12.

[0045] Please see Figure 1 It also includes a water outlet pipe, which includes a second pipe body, a second connector, and a second flange. The second connector is fixedly disposed at the end of the second pipe body, and the second flange is fixedly disposed on the second connector. The second flange is connected to the third flange face 19 and presses against the third sealing ring. The second connector portion extends into the water outlet 13.

[0046] The third sealing ring can be tightened by connecting the second flange to the third flange face 19. The second joint extends into the outlet 13. When the mud pump is working, the second joint will vibrate and come into contact with the third conical surface 16. The third reinforcing hard layer 161 can protect the third conical surface 16.

[0047] Please see Figure 1 A second damping pad is provided between the second joint and the second flange.

[0048] The second shock-absorbing pad is fitted onto the second connector, and its outer diameter is greater than or equal to the diameter of the right end of the second connector. This ensures that after the second connector is inserted into the outlet, the second shock-absorbing pad contacts the outlet, thus achieving a shock-absorbing effect.

[0049] Please see Figure 1 The outer wall of the second shock-absorbing pad is provided with a second anti-slip texture.

[0050] The second anti-slip texture is designed to increase the anti-slip effect after the second shock-absorbing pad fits into the water outlet.
