Abstract
The utility model has been announced a kind of improved modulating valve, comprise valve body, in on valve body, be provided with liquid inlet pipe and drain pipe, and in valve body, be provided with spool, be connected with spool and can promote the valve rod that spool moves in valve pocket, it is characterized in that: on described valve body, be provided with fitting seat, fitting seat is movably arranged on valve body, and valve rod runs through fitting seat; On described valve rod, be provided with Electric actuator; Described liquid inlet pipe is vertical setting with drain pipe in valve body, and is provided with spool in the joint of liquid inlet pipe and drain pipe, and spool connects valve rod.In the utility model, the design of the column of spool uniqueness, only needs vertical regulating valve stem when adjusting, has not only reduced the resistance of flow of fluid, and maintenance and safeguard simple and conveniently, cost is low, simultaneously, spool face wraps up with rubber ring, has evaded the requirement higher to spool machining accuracy, and sealing is reliable.
Description
Technical field
The utility model belongs to modulating valve field, specifically, relates to a kind of improved modulating valve.
Background technique
Along with scientific and technical progress, the modulating valve that is used in the production automation controlling fluid flow is generally for industry-by-industry.And for heating power, chemical industry control system, as the modulating valve of the every quality of final control procedure medium and safety index, play an important role at aspects such as steady production, optimization control, maintenance and cost of overhaul controls.
The modulating valve of prior art, after long-time use, there will be the situation that fluid resistance is large, and such situation is generally to reinstall or dismantle rear maintenance, and maintenance difficulty is large, and cost is high.
Model utility content
For solving the problem in background technique, the utility model provides the improved modulating valve that a kind of reasonable in design, fluid resistance are little, be convenient to maintenance.
The technical solution of the utility model is:
A kind of improved modulating valve, comprise valve body, in on valve body, be provided with liquid inlet pipe and drain pipe, and in valve body, be provided with spool, be connected with spool and can promote the valve rod that spool moves in valve pocket, it is characterized in that: on described valve body, be provided with fitting seat, fitting seat is movably arranged on valve body, and valve rod runs through fitting seat; On described valve rod, be provided with Electric actuator; Described liquid inlet pipe is vertical setting with drain pipe in valve body, and is provided with spool in the joint of liquid inlet pipe and drain pipe, and spool connects valve rod.
As a kind of technological scheme of optimization, described spool is column, is arranged in liquid inlet pipe, and is closely provided with some circle rubber rings at valve core outer surface.
As a kind of technological scheme of optimization, Electric actuator comprises the final controlling element being in transmission connection with valve rod.
As a kind of technological scheme of optimization, in described fitting seat, be provided with some roller bearings, roller bearing is arranged between valve rod and fitting seat.
Owing to having adopted technique scheme, compared with prior art, in the utility model, the design of the column of spool uniqueness, only needs vertical regulating valve stem when adjusting, has not only reduced the resistance of flow of fluid, and keep in repair and safeguard simple and convenient, cost is low, and meanwhile, spool face wraps up with rubber ring, evaded the requirement higher to spool machining accuracy, sealing is reliable.
Brief description of the drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
Embodiment
As shown in Figure 1, a kind of improved modulating valve, comprises valve body 6, is provided with liquid inlet pipe 7 and drain pipe 5 on valve body 6, and in valve body 6, is provided with spool 8, is connected with spool 8 and can promotes spool 8 mobile valve rod 2 in valve pocket.On described valve body 6, be provided with fitting seat 4, fitting seat 4 is movably arranged on valve body 6, and valve rod 2 runs through fitting seat 4.On described valve rod 2, be provided with Electric actuator.Described liquid inlet pipe 7 is vertical setting with drain pipe 5 in valve body, and is provided with spool 8 in the joint of liquid inlet pipe and drain pipe, and spool 8 connects valve rod 2.
In the present embodiment, described spool 8 is column, is arranged in liquid inlet pipe 7, and is provided with some circle rubber rings 9 in spool 8 intimate.
Electric actuator comprises the final controlling element 1 being in transmission connection with valve rod.In described fitting seat 4, be provided with some roller bearings 3, roller bearing 3 is arranged between valve rod 2 and fitting seat 4.
In the utility model, the design of the column of spool uniqueness, only needs vertical regulating valve stem when adjusting, has not only reduced the resistance of flow of fluid, and maintenance and safeguard simple and conveniently, cost is low, simultaneously, spool face wraps up with rubber ring, has evaded the requirement higher to spool machining accuracy, and sealing is reliable.
The utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technological scheme, all belong to protection domain of the present utility model.
