Embodiment 1

[0032] This embodiment provides a sleeve-type integrated desuperheater, such as figure 1 As shown, it includes a support assembly, a valve stem 4, a sealing assembly and a temperature reduction adjustment assembly, etc.

[0033] Wherein, the support assembly includes a pipe body 3 and a valve body 6, and a housing chamber is opened in the pipe body 3 (the housing chamber usually runs through the pipe body 3 and is coaxial with the pipe body 3, and the size of the outer end of the housing chamber is generally larger than its inner part), one end of the valve body 6 is connected to one end of the pipe body 3 and the other end is provided with a communication seat (the communication seat is also coaxial with the pipe body 3), and the valve body 6 is provided with a A flow passage communicated between the chamber and the communication seat and a water inlet pipe (the water inlet pipe has a desuperheating water inlet 25) communicated with the flow passage is provided on its side wa...

Embodiment 2

[0052] This embodiment provides a sleeve-type integrated desuperheater, such as Figure 4 As shown, it includes a support assembly, a valve stem 4', a sealing assembly and a temperature reduction adjustment assembly, etc.

[0053] Wherein, the supporting assembly includes a pipe body 3' and a valve body 6', and a housing chamber is opened in the pipe body 3' (the housing chamber usually runs through the pipe body 3' and is coaxial with the pipe body 3', and outside the housing chamber The size of the end part is usually larger than its relative inner part), one end of the valve body 6' is connected to one end of the pipe body 3' and the other end is provided with a communication seat (the communication seat is also coaxial with the pipe body 3'), the A flow channel communicating with the accommodating chamber and the communication seat is opened in the valve body 6', and a water inlet pipe communicating with the flow channel is provided on its side wall. The valve stem 4' is ...

Embodiment 3

[0056] This embodiment provides a sleeve-type integrated desuperheater, such as Image 6 As shown, it is basically similar in structure to Embodiment 2, except that the nozzle 1", valve plug 2", pipe body 3" and valve stem 4" have slightly different structures and do not contain a sleeve.

Abstract

The invention discloses a sleeve type integrated desuperheater and an assembling method and application thereof. The sleeve type integrated desuperheater comprises a supporting assembly, a valve rod,a sealing assembly, and a temperature reduction adjusting assembly, the temperature reduction adjusting assembly comprises a nozzle installed at the other end of a pipe body and a valve plug, one endof the valve plug is connected with the other end of the valve rod, and the other end of the valve plug is matched with the nozzle; the temperature reduction adjusting assembly has a first state and asecond state. When the temperature reduction adjusting assembly is in the first state, the other end of the valve plug or the outer wall of the valve plug makes contact with the nozzle in a sealed mode; and when the temperature reduction adjusting assembly is in the second state, an accommodating cavity communicates with the nozzle. Therefore, only one part moves, the valve plug with the hard surface and the plug-in nozzle with the internal part made of high-quality alloy steel are good in tightness, high in reliability and abrasion resistance and convenient to install.

Description

technical field [0001] The invention belongs to the technical field of desuperheaters, and relates to a desuperheater, in particular to a sleeve-type integrated desuperheater and its assembly method and application. Background technique [0002] The steam desuperheater is controlled by the signal from the temperature controller and is an operating part in the temperature control system. The task of the desuperheater is to evenly spray the amount of water corresponding to the signal received by the actuator into the steam pipe. In order to ensure the function and service life of the desuperheater, all control circuits must be properly arranged and functioning properly. Oscillations in temperature control can cause thermal fatigue in the desuperheater and internal parts. [0003] The Chinese utility model patent with application number 201921631445.4 discloses a new type of superheated steam desuperheater, which consists of a pipe body, a spray cooling device, a flow guide d...
