Abstract
The utility model discloses a switching-connecting seal head used for pipeline hydraulic pressure leak detection. The switching-connecting seal head comprises a seal head (2) and a nut (3) mounted on the seal head (2) in a sleeved mode, wherein one end of the seal head (2) is connected with a connecting head (4) of equipment to be detected, the other end of the seal head (2) is connected with a conical surface connecting head (5), a seal ring (1) is mounted between the seal head (2) and the conical surface connecting head (5), a cone-shaped structure preventing the seal ring (1) from falling out is arranged at one end, where the seal ring (1) is mounted, on the seal head (2), and the cone-shaped structure is a folding edge which is arranged on an end portion of the seal head (2) and forms an inclined angle of 85 degrees with an axis of the seal head (2). According to the switching-connecting seal head used for pipeline hydraulic pressure leak detection and provided with the structure, through installation of the seal ring between the seal head and the conical surface connecting head, when leak detection equipment starts to work, an O-shaped ring deforms and plays a good role in sealing, sealing effects of pipeline connection are improved, and at the same time, damage to a seal surface of the seal head and the conical surface connecting head can be avoided.
Description
Technical field
The utility model relates to a kind of switching end socket for the hydraulic pressure of pipe line leak detection.
Background technique
At present, some pipelines that are used for fluid needed pipeline is carried out leak test before coming into operation, in the prior art, because the variation that pipeline connects, usually use the conical surface seal mode that different pipelines is connected and seal structure shown in Figure of description 1.Yet this kind leak detection sealing means is rigid connection, and is larger to the damage of sealing surface after the leak detection, and sealing effect is bad, easily produces and leaks.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of switching end socket for the hydraulic pressure of pipe line leak detection for problems of the prior art, its objective is the damage of avoiding sealing surface, improves the sealing effect between the pipeline.
The technical solution of the utility model is that switching end socket that this kind is used for the hydraulic pressure of pipe line leak detection comprises end socket and is sleeved on nut on the end socket, one end of described end socket is connected with the connecting head of equipment to be hunted leak, the other end of described end socket is connected with conical surface connecting head, and between end socket and the conical surface connecting head seal ring is installed.
Described seal ring is O type circle.
The end that seal ring is installed on the described end socket is provided with the cone structure that prevents that seal ring from coming off.
Cone structure on the described end socket is to be provided with the flanging that has 75 ° of-90 ° of angles with the end socket axis in the end of end socket.
Angle between flanging on the described end socket and the end socket axis is preferably 85 °.
This kind with said structure is used for the switching end socket of hydraulic pressure of pipe line leak detection by between end socket and the conical surface connecting head seal ring being installed, when leak test plant is started working, O type circle deforms and starts good seal action, improved the sealing effect that pipeline connects, simultaneously, can avoid the damage of sealing surface on end socket and the conical surface connecting head.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In Fig. 1-2,1: seal ring; 2: end socket; 3: nut; 4: the connecting head of equipment to be hunted leak; 5: conical surface connecting head.
Embodiment
Figure 1 shows that the structural representation of prior art.Because the variation that pipeline connects is usually used the conical surface seal mode that different pipelines is connected and sealed, yet this kind leak detection sealing means is rigid connection, and is larger to the damage of sealing surface after the leak detection, and sealing effect is bad, easily produces and leaks.
Fig. 2 is structural representation of the present utility model.The switching end socket that this kind is used for the hydraulic pressure of pipe line leak detection comprises end socket 2 and is sleeved on nut 3 on the end socket 2, one end of end socket 2 is connected with the connecting head 4 of equipment to be hunted leak, the other end of end socket 2 is connected with conical surface connecting head 5, and between end socket 2 and the conical surface connecting head 5 seal ring 1 is installed, seal ring 1 is O type circle.
The end that seal ring 1 is installed on the end socket 2 is provided with the cone structure that prevents that seal ring 1 from coming off, cone structure on the end socket 2 is to be provided with the flanging that has 75 ° of-90 ° of angles with end socket 2 axis in the end of end socket 2, and the angle between the flanging on the end socket 2 and end socket 2 axis is preferably 85 °.
This kind with said structure is used for the switching end socket of hydraulic pressure of pipe line leak detection by between end socket and the conical surface connecting head seal ring being installed, when leak test plant is started working, O type circle deforms and starts good seal action, improved the sealing effect that pipeline connects, simultaneously, can avoid the damage of sealing surface on end socket and the conical surface connecting head.
