[0015] This utility model's sealing fixture comprises a sealing seat, a sealing ring, a pressure ring, and a pressure block. When performing a seal test on a spray bar, the pressure ring is first placed on the end cap, followed by the sealing ring. The end cap is then inserted into the groove of the sealing seat, at which point the sealing ring is embedded in the annular groove. The pressure ring is then moved to press against the sealing seat, and the pressure block is pressed onto the pressure ring. The pressure block and sealing seat are then clamped and fixed from both ends using a clamp. The pressure ring, in conjunction with the annular groove, compresses and deforms the sealing ring, increasing the pressure between the sealing ring and the side wall of the end cap, thus improving the sealing effect and ensuring the accuracy of the seal test. This sealing fixture has a simple structure, is easy to install, improves testing efficiency, and is suitable for batch testing of spray bars.

[0030] Please refer to Figures 1-6 An embodiment of this utility model provides a sealing fixture for a part, comprising:

[0031] The sealing seat 1 has a groove 11 on one side, and a ring groove 12 is formed at the opening of the groove 11.

[0032] The sealing ring 2 is fitted onto the end cap 51 of the spray bar 5 and is located on the side of the oblique hole 52 of the end cap 51 away from the end hole 52.

[0033] The pressure ring 3 is located on the outside of the groove 11 and is used to cooperate with the ring groove 12 to compress the sealing ring 2;

[0034] The pressure block 4 is located on the side of the pressure ring 3 away from the sealing seat 1, and is used to press the pressure ring 2 and the spray bar 5.

[0035] In this embodiment, when performing a sealing test on the spray bar 5, the pressure ring 3 is first placed on the end cap 51, and then the sealing ring 2 is placed on the end cap and moved to the side of the oblique hole 52 away from the end hole 52; then the end cap 51 is embedded into the groove 11 of the sealing seat 1, so that the sealing ring 2 is embedded into the annular groove 12; then the pressure ring 3 is moved to press on the sealing seat 1, and then the pressure block 4 is pressed on the part of the spray bar 5 away from the end cap 51 and the pressure ring 3; then the pressure block 4 and the sealing seat 1 are clamped and fixed from both ends by the clamp, and the pressure ring 3 cooperates with the annular groove 12 to compress the sealing ring 2 to deform, increasing the pressure between the sealing ring 2 and the side wall of the end cap 51, thereby sealing the oblique hole 52 and the end hole 52 in the groove 11.

[0036] At this point, the inlet of the spray bar 5 is connected to the testing device. The testing device injects high-pressure medium into the spray bar 5 and maintains the pressure for a period of time, checking whether there is any medium leakage at the weld. If there is no leakage, the weld is qualified; otherwise, it is unqualified. The sealing fixture of this application has a simple structure, is easy to install, has high testing efficiency, is suitable for batch testing of the spray bar 5, and has a good sealing effect, ensuring the accuracy of the sealing test.

[0037] In a preferred embodiment, such as Figure 6 As shown, the inner diameter of the groove 11 is clearance-fitted with the outer diameter of the end cap 51, ensuring a high degree of fit and sealing effect; the depth of the groove 11 is greater than the horizontal distance between the opening of the oblique hole 52 and the opening of the end hole 53, so that the oblique hole 52 and the end hole 53 can be sealed in the groove 11 at the same time, ensuring effective sealing.

[0038] In a preferred embodiment, the sealing ring 2 is an O-ring; the inner diameter of the sealing ring 2 is 3-5 mm smaller than the outer diameter of the end cap 51, ensuring the sealing effect of the sealing ring 2; the width of the annular groove 12 is 0.1-0.3 mm larger than the wire diameter of the sealing ring 2, and the depth of the annular groove 12 is 1 / 2-2 / 3 of the wire diameter of the sealing ring 2, so that the sealing ring 2 in the annular groove 12 is squeezed and deformed, thereby improving the sealing effect of the sealing ring 2.

[0039] In a preferred embodiment, such as Figure 6 As shown, the inner diameter of the pressure ring 3 and the outer diameter of the end cap 51 are in clearance fit, resulting in a high degree of fit; the outer diameter of the pressure ring 3 is larger than the outer diameter of the annulus formed by the ring groove 12, ensuring that the pressure ring 3 effectively compresses the sealing ring 2.

[0040] In a preferred embodiment, such as Figure 6 As shown, a pressure groove 41 is provided on the side of the pressure block 4 near the pressure ring 3. The width of the pressure groove 41 is greater than the inner diameter of the pressure ring 3 and less than the outer diameter of the pressure ring 3. The bottom of the pressure groove 41 presses and fixes the spray rod 5, and the pressure groove end of the pressure block 4 presses and fixes the pressure ring 3.

[0041] In this embodiment, the pressure block 4 squeezes the pressure ring 3, which in turn squeezes the sealing ring 2 to deform it and improve the sealing effect; the part of the spray rod 5 opposite to the end cap 51 is embedded in the pressure groove 41 to limit and fix the spray rod 5, so that the end cap 51 will not come out of the groove 11, thus ensuring the reliability of the sealing test.

[0042] In a preferred embodiment, such as Figure 4 and Figure 6 As shown, the side of the sealing seat 1 away from the pressure ring 3 is a vertical first clamping surface 13; the side of the pressure block 4 away from the pressure ring 3 is a vertical second clamping surface 42, which facilitates clamping and fixing the sealing fixture with flat-nose pliers.
