Description
Technical Field
The utility model discloses a right-angle VCR-KF 25 adapter, belonging to the field of hydrogen storage material performance testing devices.
Background
Hydrogen has received wide attention because of its high heat of combustion and its combustion products are water and do not pollute the environment, so hydrogen energy is expected to replace the traditional fossil energy. In many links where hydrogen energy is used, storage and transportation of hydrogen are bridges connecting hydrogen sources and applications, and researchers have developed various hydrogen storage materials. In order to evaluate the quality of the performance of the hydrogen storage material and the applicable conditions and occasions, a hydrogen storage material performance test system is indispensable.
One of the main devices currently used to test the performance of hydrogen storage materials is the PCT (pressure-composition-temperature) tester. In order to realize the hydrogen charging and discharging circulation in the testing process, the system needs to be vacuumized, and therefore, the PCT tester is often connected with a vacuum pump. The connector of the PCT tester is a VCR connector, the connector of the vacuum pump is a KF25 connector, and a VCR-to-KF 25 adapter is designed for connecting the VCR connector and the vacuum pump connector. However, the current VCR KF25 adapters are all straight-through type, and only two connectors can be fixed on a straight line. Then, under the condition that the space is limited, if the PCT tester is too close to the vacuum pump, the pipeline of the vacuum pump can only be bent, so that on one hand, smooth passing of gas in the vacuumizing process is influenced, particularly, the gas is not easy to exhaust at low pressure, and on the other hand, the joint position generates stress to influence the joint sealing property.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a right-angle VCR conversion KF25 adapter.
The purpose of the utility model is realized, and the provided technical scheme is as follows:
the utility model provides a right angle shape VCR changes KF25 adapter, this right angle shape VCR changes KF25 adapter includes:
arranging a VCR nut to be connected with a VCR joint of the hydrogen storage material performance tester, wherein the VCR nut is movable;
the VCR nut is provided with a leakage detecting hole;
the two ends of the welding elbow are respectively connected with the VCR nut and the KF25 flange, so that the VCR nut and the KF25 flange form a right angle.
Further, the VCR KF25 adapter is connected to the PCT tester by turning the VCR nut.
Furthermore, the leakage detecting hole is arranged to detect the air tightness of the adapter after the equipment is connected.
Furthermore, one end of the welding elbow, which is connected with the PCT tester, is a VCR connecting rod, and the VCR connecting rod is a spherical joint, so that the joint pressure is increased when a VCR nut is screwed, and the device has better air tightness.
Further, the KF25 flange is connected with a vacuum pump KF25 connector.
Furthermore, rubber sleeves corresponding to the connectors are arranged at two ends of the right-angle VCR KF25 switching connector. When the device is idle, the VCR nut and the KF25 flange are protected, so that the VCR nut and the KF25 flange are prevented from being polluted by dust, and the air tightness of the joint is prevented from being influenced.
Compared with the prior art, the utility model has the following remarkable advantages:
1. according to the right-angle VCR conversion KF25 conversion adapter, the conversion adapter is turned by 90 degrees by welding the elbow, so that the vacuum pump pipeline can be prevented from being bent under the condition of small space, air flow can smoothly pass through the vacuum pump pipeline, the sealing performance of the adapter is enhanced, and the space utilization rate and the test accuracy of a laboratory are greatly improved.
2. The welding elbow is arranged to be a right angle, so that the vent pipe of the vacuum pump is prevented from being bent when the vacuum pump is connected with a PCT tester in a limited space, gas smoothly passes through the vent pipe, stress generated by bending of a pipeline is avoided, and sealing is better.

Detailed Description
With reference to fig. 1 to 3, the right-angle VCR-KF 25 adapter according to the present invention includes: VCR nut 1, leak detection hole 2, welding elbow 3, KF25 flange 4.
The VCR nut 1 (fig. 1) is connected to the VCR joint of the hydrogen storage material performance tester (PCT tester), wherein the VCR nut is movable, and the VCR joint KF25 adapter can be connected to the PCT tester by simply rotating the VCR nut 1.
The VCR nut 1 is provided with a leak detection hole 2 (see fig. 1) for detecting the air tightness at the adapter after the connection of the devices is completed.
Welding elbow 3 (like figure 1) connects VCR nut 1 and KF25 flange 4, makes VCR nut 1 and KF25 flange 4 form the right angle, and crooked vacuum pump breather pipe when avoiding vacuum pump and PCT tester to be connected in limited space makes gas smooth to pass through like this, and on the other hand avoids the crooked production stress of pipeline to better sealed.
The VCR connects the pole on the welding elbow 3 and is connected with PCT tester to be the ball joint (as shown in fig. 4), is favorable to when screwing the VCR nut 1, increases the joint pressure, makes the device have better gas tightness.
The KF25 flange 4 (shown in FIG. 2 and FIG. 3) is connected with a vacuum pump KF25 connector.
The right-angle VCR changes KF25 adapter is connected with the vacuum pump through KF25 flange at first, and the rethread VCR nut is connected with the PCT tester to play the effect of adapter, through leak hunting hole 2 detection device's leakproofness.
This right angle shape VCR changes KF25 adapter both ends and all is furnished with and connects corresponding rubber sleeve, and when the device was idle, protection VCR nut 1 and KF25 flange 4 prevented that it is infected with the dust, influences and connects the gas tightness.
