Abstract
The invention relates to improvements in or relating to a desuperheater for controllable injection of cooling water in a steam or gas line (17), said desuperheater device including an insertion tube (1) extending inside the pipe (17), said tube (1) having a conical outlet nozzle (7) with a valve body (5) movably arranged in a hole (2) in the insertion tube (1) such as to form a regulating port (4). The hole (2) in the insertion tube (1) opens out into a rotation chamber (3) with the centerline (10) of the hole and the centerline (11) of the rotation chamber (3) disposed relative each other at an angle deviating from 90.degree. by an angle .alpha., and where the angle .alpha. is greater than 0.degree. but less than 30.degree..
Claims8
A desuperheater device for the controllable injection of cooling water into a steam or gas line, comprising:
- an insertion tube extending into the line;
- a conical outlet nozzle having a valve body movably mounted within the hole in the insertion tube so as to form a regulating port;
- and
- a groove extending along the valve body, wherein the groove is positioned in the hole such that the groove opens along the tangent of a curved surface of the rotation chamber, and wherein the rotation chamber has a centerline which is disposed relative to the centerline of the hole to form an angle which deviates from 90.degree. by an angle .alpha., angle .alpha. being within the range of 0.degree. to 30.degree..
A desuperheater device for the controllable injection of cooling water into a steam or gas line, comprising:
- an insertion tube extending into the line, the insertion tube including a hole having a centerline and an inlet opening, wherein the hole opens into a rotation chamber;
- a conical outlet nozzle having a valve body movably mounted within the hole to form a regulating port, the valve body including a flat machined surface and a curved surface;
- a sealing surface on the valve body which forms a seal with a seat on the inlet opening of the hole;
- a groove extending along the curved surface of the valve body from below the sealing surface to a tip of the valve body, wherein the groove is positioned in the hole such that the groove opens out along the tangent of a curved surface of the rotation chamber, and wherein the rotation chamber has a centerline which is disposed relative to the centerline of the hole to form an angle which deviates from 90.degree. by an angle .alpha., angle .alpha. being within the range of 0.degree. to 30.degree.;
- and
- a rotation stop which abuts against the flat machined surface of the valve body to maintain the position of the groove in the hole.
