Description

Technical Field

[0001] The utility model relates to the technical field of valve body flow channel sealing test auxiliary tools, in particular to a sealing test connector for a vertical flow channel. Background Art

[0002] It is inevitable that vertical flow channels will be formed on the transmission lines of liquids and gases, and each flow channel is also correspondingly installed with a regulating valve for controlling the fluid transmission speed, pressure, etc. Generally, a pressure measuring channel connected to the fluid channel in the regulating valve is provided on the fluid inlet and fluid outlet of the regulating valve, and a pressure measuring valve is correspondingly installed in the pressure measuring channel. After the pressure measuring valve is installed, the sealing of the channel in which it is located must be ensured to ensure the leakage-free transmission of the fluid, and the fluid channel in the valve and the pressure measuring channel will also form a cross-connected vertical flow channel. In order to ensure the safe and smooth use of the pipeline, the above-mentioned various vertical flow channels need to be tested for sealing. For example, when conducting a sealing test on a regulating valve, the fluid channel in the valve will be closed by the valve plate first, and the sealing component will be blocked on the port of the valve, so that the pressure measuring channel connected to the fluid channel in the valve forms a closed cavity; then the sealing component is connected to the high-pressure gas source, and high-pressure gas is sent into the closed cavity, and the pressure in the cavity is detected with the help of the relevant pressure display component to judge the sealing of the pressure measuring channel. There is a possibility of pressure release around the valve plate and the sealing component, so it is difficult to quickly know that the pressure release is caused by poor sealing of the pressure measuring channel. The above technical problems also exist when performing sealing tests on vertical flow channels on pipelines. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing test connector of the vertical flow channel is set at the intersection of two mutually perpendicular flow channels, such as the main channel and the branch channel, to perform a sealing test on the vertical branch channel. Specifically, it includes a test support base 1, and the bottom surface of the test support base 1 is set as a spherical structure, which is used to better contact with the arc-shaped inner part of the main channel to improve the support stability during the test.

[0018] The upper limit position of the test support base 1 is movably inserted with a test support top rod 2, and the test support top rod 2 cooperates with the test support base 1 to achieve support and fixation in the channel when the entire device is used for testing. The upper limit position sleeve of the test support top rod 2 located in the test support base 1 is provided with a top rod pressing spring 3. When the test support base 1 and the test support top rod 2 are placed in the main channel, the test support top rod 2 is always in an upper position under the elastic force of the top rod pressing spring 3, so that the inner wall of the main channel is used to make this embodiment stand upright and fixed in the main channel.

[0019] A hollow test flow channel 4 is provided in the test support top rod 2, and a test pressure source interface 5 connected to the test flow channel 4 is provided on the side of the test support top rod 2. A test flow nozzle 6 is fixedly installed on the top of the test support top rod 2, and the test flow nozzle 6 is connected to the test flow channel 4. After the present embodiment is placed and fixed in the main channel, the test flow nozzle 6 will extend into the branch channel. After the test pressure source interface 5 is connected to an external test pressure source such as high-pressure gas, high-pressure water, etc., the test pressure source will enter the branch channel through the test pressure source interface 5, the test flow channel 4 and the test flow nozzle 6, and the sealing of the branch channel can be tested.

[0020] A test sealing ring 7 is mounted on the test flow nozzle 6. When the test support push rod 2 is pushed up with the help of the push rod clamping spring 3, the test sealing ring 7 will cooperate with the top end of the test support push rod 2 under the blocking effect of the inner wall of the main channel, thereby forming a seal on the surrounding side of the test flow nozzle 6, eliminating the possibility of pressure relief here, thereby ensuring the accuracy of the test.

[0021] In this embodiment, the outer diameter of the test flow nozzle 6 is set smaller than the outer diameter of the top of the test support top rod 2, and the test sealing ring 7 is limited to the top of the test support top rod 2. Generally, the inner diameter of the branch channel will be much smaller than the inner diameter of the main channel. Setting the outer diameter of the test flow nozzle 6 smaller than the outer diameter of the top of the test support top rod 2 can enable the test flow nozzle 6 to be smoothly inserted into the branch channel. The test flow channel 4 can also be set through the test support top rod 2, so that the test pressure source entering the test flow channel 4 will also move downward, and the test support base 1 is supported externally, which indirectly increases the pressure on the test sealing ring 7, thereby playing a role in strengthening the seal. After the test flow channel 4 is set through the test support top rod 2, a flow channel sealing ring 8 needs to be set on the test support top rod 2 located in the test support base 1 to achieve the seal between the test support top rod 2 and the test support base 1, so as to prevent the pressure release of the test pressure source on the contact surface between the two, which helps to ensure the accuracy of the sealing test.

[0022] The test support push rod 2 is provided with a push rod tightening adjustment device, which is used to fine-tune the tightening effect of the test support push rod 2 during use to improve the sealing effect of each sealing surface. Specifically, the push rod tightening adjustment device includes a push rod adjusting threaded sleeve 9 provided on the outer periphery of the test support push rod 2, and the outer peripheral surface of the push rod adjusting threaded sleeve 9 is provided with an external thread, and a push rod adjusting nut 10 used in conjunction with the push rod adjusting threaded sleeve 9 is threadedly connected to the push rod adjusting threaded sleeve 9. When it is necessary to strengthen the seal, the push rod adjusting nut 10 is rotated to increase the overall length of the push rod adjusting threaded sleeve 9 and the test support push rod 2 is pushed up. It is also possible not to provide the push rod adjusting threaded sleeve 9, but to directly provide an external thread on the outer surface of the top of the test support push rod 2 to threadably cooperate with the push rod adjusting nut 10.

[0023] like Figure 4 As shown, this embodiment is used in the sealing test of the regulating valve, and is fixed in the main channel 12 in the valve for the sealing test of the pressure measuring channel 13 of the valve. When in use, the test support push rod 2 and the test support base 1 are first supported and fixed in the main channel 12 in the valve under the action of the push rod clamping spring 3, and the test nozzle 6 is extended into the pressure measuring channel 13, and the test pressure source interface 5 is used to connect with the external test pressure source to start the test. If the sealing performance is not ideal, the push rod adjustment nut 10 can be rotated to strengthen the tightening effect of the test support push rod 2. After the test is completed, the push rod adjustment nut 10 is first reversed and returned to its original position, and then the test support push rod 2 is pressed down to separate the test nozzle 6 from the pressure measuring channel 13, and the entire connector can be taken out. The operation is simple, easy to use, and the test efficiency is high and the results are accurate.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
