Description
Technical field
The utility model belongs to valve technology field, particularly relates to a kind of insulation jacket type HVAC control valve.
Background technique
Control valve is formed primarily of two main assembly parties, valve body assembly parts and actuator's assembly parts (or actuator system), be divided into four large series, single seat series of control valves, two-seater series of control valves, sleeve series of control valves and self-powering type series of control valves.The mutation of Four types valve can cause various different applicable structure, the application that often kind of structure has it special, feature, merits and demerits.Although some control valve has wider application operating mode compared with other valves, control valve can not be suitable for all operating modes, jointly to build the best solution of strengthening the property, reducing costs.Modulating valve is the final controlling element in robot control system(RCS), and its application quality directly reacts on the regulation quality of system.As the final element in process control, people had the understanding upgraded the significance past to it.The quality of modulating valve application, except whether product sole mass, user correctly install, use, safeguard, correctly calculates, type selecting is very important.Due to the error of Lectotype and calculation, cause system start-stop to stop, what have even cannot come into operation, so should be familiar with valve significance at the scene for user and system designer, must cause enough attention to the type selecting of modulating valve.The HVAC control valve of current practical application, the frictional force of valve rod is comparatively large, and rotational resistance is also just comparatively large, and when the temperature difference is less, reaction sensitivity is not high, and implementation result is not good.
Summary of the invention
The utility model provides and a kind of insulation jacket type HVAC control valve, to solve the larger problem of the valve stem end frictional force that proposes in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of insulation jacket type HVAC control valve, it is characterized in that: comprise valve body, the bottom surface of described valve inner is provided with valve seat, described valve seat upper surface is provided with lower limit groove, valve rod is provided with in described valve body, the bottom of described valve rod is positioned at lower limit groove, lower bearing is provided with between described valve rod and valve seat, the both sides of described valve rod are provided with spool, the first flat key is provided with between described valve rod and spool, second flat key, described valve body top is provided with circular hole, described valve rod is through circular hole, seal ring is provided with in described circular hole, stop sleeve is provided with above described valve body, groove is provided with bottom described stop sleeve, described valve rod is through groove, described stop sleeve inner hollow, and inside is provided with permanent magnet cover, brass magnetosheath, described permanent magnet cover is enclosed within the outside of valve rod, described brass magnetosheath is enclosed within the outside of permanent magnet cover, coupling sleeve is provided with above described stop sleeve, the bottom surface of described coupling sleeve is provided with upper limit position groove, the top of described valve rod is positioned at upper limit position groove, upper bearing (metal) is provided with between described valve rod and coupling sleeve, the top of described coupling sleeve is provided with elongated slot, insulating rubber rod is provided with in described elongated slot, spring seat is provided with above described coupling sleeve, described spring seat is provided with Compress Spring, the outer surface cover of described spring seat has shell, the bottom of described shell is provided with protuberance, the side of described coupling sleeve is provided with block, described protuberance is positioned at below block, temperature bag is provided with between described spring seat and shell.
