Abstract
The utility model discloses a high temperature adjustable valve, which is composed of an actuating mechanism and a valve body. The actuating mechanism realizes the control and adjustment of the valve, the valve body has three gateway connection tubes, and cold flow and the mixed flow go in and out of the valve body horizontally. The heat flow go into the valve body from the bottom, the inner wall of the heat flow connection tube is provided with an insulated lining and a wear-resistant lining, the two linings avoid the erosion of the heat flow medium on one hand and prevent the connection tubes from the high temperature of the heat flow on the other hand, so the thermal deformation of the valve body is relieved. The valve core contacted with the heat flow is made of the composite of heat-resisting steel and ceramics, so the utility model has high temperature resistance and corrosion resistance.
Description
The utility model relates to a kind of modulating valve, particularly a kind of Three way type modulating valve.
The Three way type modulating valve of domestic production at present is made up of valve body, valve seat, spool, valve rod and actuator.Valve body has three gateways to link to each other with pipeline, and valve seat is fixed on the valve body, and spool is by valve rod moving linearly under the drive of actuator, and different apertures is corresponding to different flows, thereby realization is to the control of logistics.The Three way type modulating valve is divided into diverter valve and two kinds on interflow valve by the mode of action.The interflow valve mixes when being two kinds of fluids by valve and produces the third fluid, be mixed into temperature when perhaps two kinds of fluid at differing temperatures are by valve between the third fluid between the above two, this kind valve has two imports and an outlet, generally work at normal temperatures, when being used in high temperature or high temperature difference, because high temperature fluid passes through, cause tube expansion, this kind valve can not adapt to this expansion, produce big stress and be out of shape, cause the damage and the leakage of connection place, especially influence is even more serious when high temperature difference.Three-way control valve in " product sample " that Wuzhong instrucment and meter plant edits and publishes is exactly this type of valve.
The purpose of this utility model provides a kind of three-way control valve that is used under high temperature difference (temperature difference can the reach 1000 ℃) operating mode.
The technical solution adopted in the utility model is: the high temperature modulating valve, valve body has cold flow to take over, hot-fluid is taken over, mixed flow is taken over three gateways and is taken over, described cold flow is taken over, mixed flow is taken over and is positioned at the valve body two ends, be horizontal arrangement, hot-fluid is taken over the bottom that is positioned at valve body, valve seat is arranged at the top that hot-fluid is taken over, spool is positioned at the top of valve seat, Stuffing box and actuator are supported on the blind flange of valve body top, spool links to each other with actuator by valve rod, and under the drive of actuator, vertically moving linearly, it is characterized in that: the inwall that hot-fluid is taken over is lined with insulated lining and wear resistance lining, and spool is to make with refractory steel and ceramic combination.
The utility model is because the inwall of taking at hot-fluid is lined with insulated lining and wear resistance lining, and these two kinds of linings can prevent washing away of hot-fluid medium on the one hand, can stop the high temperature of hot-fluid to pass in the adapter on the other hand, can alleviate the thermal distortion of valve body.Spool is made with refractory steel and ceramic combination, and is not only high temperature resistant but also corrosion-resistant.The utility model is used in the oil refinery sulfur recovery facility, when the hot-fluid temperature is 1200 ℃～1300 ℃, and during 1000 ℃ of the temperature difference, stable performance, but long period safe operation.
Fig. 1 is a valve body subsection of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
Taking over 1 by cold flow, hot-fluid takes over 2, the blind flange 4 that the top of the Three way type valve bodies that mixed flow adapter 3 is formed has a support Stuffing box 7 and actuator to use, the lower end of valve rod 5 links to each other with spool 6, blind flange 4 is passed in the upper end, Stuffing box 7 links to each other with actuator, spool 6 under the drive of actuator, moving linearly vertically.Hot-fluid is taken over 2 inwall, be connected with upper head plate 8 and lower end sheet 9, the top of upper head plate 8 is connected with valve seat 10, the below is connected with sleeve 11, described hot-fluid takes over 2, upper head plate 8, lower end sheet 9 has been formed annular space with sleeve 11, stuffed heat insulated lining 12 in the annular space, the heat passage of valve seat 10 belows is formed by the wear resistance lining 13 that is fixed on sleeve 11 inwalls, the upper surface of upper head plate 8 and valve seat 10 also is provided with wear resistance lining 13, when hot-fluid when the bottom enters valve body, flow is along with spool 6 changes with the relative position of valve seat 10, to reach the purpose of control mixed flow temperature.
