Embodiment 1

[0023] Such as figure 1 As shown, the jacketed valve with heat preservation function of the present invention includes a straight-through valve body 1, a valve core 2 installed inside the valve body 1, a valve stem 3 connected to the valve core 2, the valve stem 3 is located above the valve body 1 and Perpendicular to the valve body 1, the outer wall of the valve body 1 on both sides of the valve stem 3 is covered with a heating jacket 4 coaxial with the valve body 1, and an annular heat storage body 5 is installed between the heating jacket 4 and the outer wall of the valve body 1. The annular heat storage body 5 is coaxial with the valve body 1 , the inner wall of the annular heat storage body 5 is closely connected with the outer wall of the valve body 1 , and the outer wall of the annular heat storage body 5 is closely connected with the inner wall of the heating jacket 4 . The annular heat storage body 5 is a honeycomb ceramic annular heat storage body. The heating jacke...

Embodiment 2

[0026] Based on Embodiment 1, a temperature sensor is inserted between the annular regenerator 5 on both sides of the valve stem 3 and the corresponding outer wall of the valve body 1, and the temperature sensing head of the temperature sensor is moved from the valve body 1 along the axial direction of the valve body 1. One end is inserted between the annular heat storage body 5 and the corresponding outer wall of the valve body 1, and the temperature sensing head of the temperature sensor is a flat temperature sensing head.

[0027] The temperature sensor is used to detect the temperature between the valve body and the annular heat storage body, monitor the heating temperature of the valve body, and avoid the valve body being in a high temperature state for a long time. It is unsafe to use the valve body in a high temperature state for a long time and will reduce its service life. .

Abstract

The invention discloses a jacket valve with a heat insulation function. The jacket valve with the heat insulation function comprises a straight-through type valve body, a valve element installed in the valve body and a valve rod connected with the valve element; and the valve rod is located above the valve body and is perpendicular to the valve body, the outer walls of the parts, on the two sidesof the valve rod, of the valve body are wrapped with heating jackets coaxial with the valve body, annular heat storage bodies are installed between the heating jackets and the outer walls of the valvebody, the annular heat storage bodies and the valve body are coaxial, the inner walls of the annular heat storage bodies are in tight connection with the outer walls of the valve body, and the outerwalls of the annular heat storage bodies are tightly connected with the inner walls of the heating jackets. The jacket valve can heat fluid in the valve body and preserve heat, the situation that thefluid is condensed in the valve in advance can be avoided, and the fluid can keep relatively good fluidity.

Description

technical field [0001] The invention relates to a straight-through valve, in particular to a jacket valve with heat preservation function. Background technique [0002] A valve is a control component in a fluid delivery system, with functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-...
