Abstract
The utility model discloses a kind of butterfly type safety check that is provided with zone of heating, described safety check comprises: valve body, flap, described flap comprises the first flap and the second flap, described valve body arranged outside has zone of heating, described zone of heating is the seal chamber of ring, it is fixedly connected on the circumference of described valve body, and it arranges inlet hole and air outlet hole, and described inlet hole is connected with thermal source; Hot gas, from described inlet hole enters described zone of heating, flows out from described air outlet hole.The utility model, compared with prior art, by zone of heating is set, solve while having dirt when condensing between sealing surface in prior art, can, by heating, be dissolved, make flap and sealing surface of seat sealing effect better, thereby meet user's user demand, be conducive to industrially promotion and application.
Description
Technical field
The utility model belongs to valve processing technique field, relates in particular to a kind of butterfly type safety check that is provided with zone of heating.
Background technique
Valve is the controlling component in fluid delivery system, have cut-off, adjusting, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various, produce and use standard without unified, production firm often goes to manufacture according to user's actual demand.
Butterfly type safety check is widely used in all trades and professions, its by medium in accordance with regulations direction flow time, flap is subject to the effect of medium power, is unlocked; When medium counter flow, because flap deadweight and flap are subject to the effect of medium opposite force, the sealing surface that makes flap and valve seat is closely sealed and close, reach the object that stops medium counter flow, still, while having dirt when condensing between sealing surface, described flap and sealing surface of seat place seepage, affected user's use.
Summary of the invention
The purpose of this utility model provides a kind of butterfly type safety check that is provided with zone of heating, and to solve in prior art, while having dirt when condensing between sealing surface, described flap and sealing surface of seat place seepage, affected user's use.Defect.
In order to realize the purpose of this utility model, the utility model provides a kind of butterfly type safety check that is provided with zone of heating, described safety check comprises: valve body, flap, described flap comprises the first flap and the second flap, described valve body arranged outside has zone of heating, the seal chamber that described zone of heating is ring, and it is fixedly connected on the circumference of described valve body, it arranges inlet hole and air outlet hole, and described inlet hole is connected with thermal source; Hot gas, from described inlet hole enters described zone of heating, flows out from described air outlet hole.
Wherein, described thermal source comprise third party's heat supply source and with described butterfly type safety check connecting tube in the thermal source that transmits, when described thermal source be with described butterfly type safety check connecting tube in transmit thermal source time, described inlet hole is all connected with described pipeline with described air outlet hole.
The utility model, compared with prior art, by zone of heating is set, solve while having dirt when condensing between sealing surface in prior art, can, by heating, be dissolved, make flap and sealing surface of seat sealing effect better, thereby meet user's user demand, be conducive to industrially promotion and application.
