Description

one

Constructions of sealing joints of the pipeline and the camera, including elastic, are known. held pressure.

The proposed device is characterized in that the Nipple joint is made in the form of a "cone-cone, the interface of which is covered by an elastic shell material on the side of the end facing the chamber. At the same time, at the end of the nipple there is a movable ring clamp with constant loading from a spring held by a clamp fixed in the body of the nipple.

As a result, regardless of the level of overpressure in the elastic sheath, the spring-loaded pressure constantly creates excessive contact pressure, sealing the nipple inlet in the region of the matching nipple and elastic sheath openings. Under the action of the pressure developed in the chamber, the cone-cone joint is self-sealing and thereby eliminates the possibility of squeezing the elastic sheath between the interfaces.

The drawing shows the proposed input. The nipple / is installed in the nest of the supporting chamber 2, in which the elastic sheath 3 is also placed. The movable ring clamp 4, which presses the elastic sheath to the nipple, is coaxial with the hole in the sheath and with the nipple channel. The spring 5 is an elastic element whose force is constantly applied to the clamp.

4. The latch 6 spring support 5, but allows you to change its rigidity. The catch is fixed in the body of the nipple.

The ring 7 fixes the position of the hole in the elastic shell relative to the nipple.

A conical rim 8 serves to prevent extrusion of the elastic sheath through the nipple seat in the support chamber.

Nipple input fixes as follows. The spring 5 is precompressed and secured with a latch and presses on the movable clamp 4, and the latter on the elastic sheath 3 around the opening in it to the end surface of the nipple. Thanks to the constant

The action of the spring 5, regardless of the amount of pressure developed in the shell 3 under the movable clamp 4, in the contact zone of the elastic shell and the nipple maintains an overpressure to ensure the tightness of the nipple input.

Under the action of pressure developed in the shell 3, the nipple is pressed tightly with a conical rim 8 to the mating surface of the socket in chamber 2. This eliminates the possibility of squeezing the elastic shell into the gap and creates a seal sufficient to maintain the pressure differential.

Subject invention

A nipple entry into the chamber with an inner elastic sheath, in which a high pressure is developed, containing a nipple joint, an elastic sheath material and a movable clamp, characterized in that, in order to seal the joint and prevent extrusion of the elastic material between the mating surfaces, “cone-cone” type with overlapping of the end face facing into the chamber, with an elastic sheath and has a spring-loaded ring clamp, which is mounted on the nipple and acts on the elastic round around the hole in it, coinciding with the nipple channel.
