AI Technical Summary
The airtightness test results of existing cold plate heat exchanger pipe fittings are inaccurate and costly, mainly due to the excessively thin bamboo-joint water taps.
A novel end-face sealing helium detector fixture is designed, which adopts a multi-layer O-ring seal and clamp structure. The fixture clamps the water nozzle and uses internal air pressure to lift the sealing ring to achieve a double seal and ensure airtightness.
This improves the accuracy of airtightness testing and reduces production costs for enterprises.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to cold plate heat exchanger pipeline joint detection technical field, concretely to a novel end face seal helium detection clamp. BACKGROUND
[0002] In prior art, cold plate heat exchanger, pipeline joint all need airtightness test, and the existing test mode is basically through manual installation of the plugging head at the bamboo joint type water nozzle to carry out airtightness detection, but because the bamboo joint type water nozzle is too thin, often leads to inaccurate test result, and the cost is relatively high, increases the cost of enterprise. UTILITY MODEL CONTENT
[0003] The utility model discloses a novel end face seal helium detection clamp to solve the problems in the background art.
[0004] To achieve the above object, the utility model provides the following technical scheme: a novel end face seal helium detection clamp, including the outer tank body, the outer tank body lower extreme is equipped with the shell body, the both sides symmetry of outer tank body is equipped with the clamp connected with it, the shell body lower extreme is equipped with the product corresponding position.
[0005] Further optimization, the outer tank body inner chamber is equipped with the tank body seal O type ring.
[0006] Further optimization, the shell body inner chamber is equipped with first inner gas tight O type seal ring and second inner gas tight O type seal ring in proper order.
[0007] Further optimization, the second inner gas tight O type seal ring is equipped with the end face seal ring away from the lower extreme of first inner gas tight O type seal ring.
[0008] Further optimization, the end face seal ring lower extreme is equipped with O type seal ring still.
[0009] Further optimization, the outer tank body with clamp is connected through the spring.
[0010] Further optimization, the clamp bottom is equipped with the clamping part for clamping the product water nozzle.
[0011] Beneficial effect
[0012] The novel end face seal helium detection clamp provided by the utility model, manual pressure clamp opens the bayonet, through the inner positioning plug product water nozzle, gently presses down, loosens the clamp, and the water nozzle is clamped, and the air inlet is entered from the air inlet, and because the limiting block is lifted by the inner gas pressure, the O ring is expanded outward, the airtightness is strengthened, the outer sealing ring O ring covers the water nozzle to realize double insurance, and the airtightness is tested, and the production cost of enterprise is reduced, and the accuracy of test result is guaranteed. BRIEF DESCRIPTION OF DRAWINGS
[0013] Fig. 1 It is a whole structure schematic view of the utility model;
[0014] Fig. 2 It is a whole structure cross section schematic view of the utility model. PREFERRED EMBODIMENT
[0015] The following is a specific embodiment of the utility model and in combination with the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.
[0016] EMBODIMENT
[0017] As Figs. 1-2 The utility model discloses a novel end face seal helium detection clamp, including outer tank body 1, the lower end of outer tank body 1 is equipped with the shell body 4, the both sides of outer tank body 1 are equipped with the clamp 2 connected with it, and the lower end of shell body 4 is equipped with product corresponding position 6.
[0018] In the embodiment, the outer tank body 1 inner chamber is equipped with tank body seal O type ring 7, and the shell body 4 inner chamber is sequentially equipped with first inner gas seal O type seal ring 8 and second inner gas seal O type seal ring 9.
[0019] The second inner gas seal O type seal ring 9 is equipped with end face seal ring 10 away from the lower end of first inner gas seal O type seal ring 8.
[0020] The end face seal ring 10 lower end is also equipped with O type seal ring 11.
[0021] The outer tank body 1 is connected with the clamp 2 through spring 3.
[0022] The clamp 2 bottom is equipped with the clamping part 12 for clamping the product water nozzle.
[0023] Artificially press the clamp to open the bayonet, insert the product water nozzle through the inner positioning plug, press down gently, loosen the clamp, clamp the water nozzle, and air is introduced from the air inlet, and because the limiting block is lifted by the inner gas pressure, the O ring is expanded outward, the air tightness is strengthened, the outer seal ring O ring covers the water nozzle to realize double insurance, and the air tightness can be tested.
[0024] Finally, it should be noted that: the above only for the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model, should be included in the protection scope of the utility model content.
