The valve cover is arranged on the valve body, the piston is disposed in the valve body, the piston is fixed to one end of the second connecting plate through the lower connecting rod, the other end of the second connecting plate is fixed to the upper connecting rod, the upper connecting rod is connected with the connecting shaft through the first connecting plate and the fastening screw, and the connecting shaft is connected with the actuator. By means of the improvement of a connecting transmission part in an operation mechanism, the connecting rod transmission device achieves the aims that response speed is high, loss is little, steam flow is controlled more accurately and water outflow of a heat exchanger is more stable.
Description
Technical field
The parts that the utility model relates to a kind of Novel temperature control valve form and preparation process, are specifically related to a kind of thermostat valve link gearing.
Background technique
Along with the development of domestic technique, thermostat valve makes rapid progress, and wherein intelligent temperature control valve is newer equipment in domestic heating system in recent years.
Thermostat valve core is exactly electric actuator, defines to be the most widely for actuator: a kind of drive unit that straight line can be provided or rotatablely move, it utilizes certain driving source and works under certain control signal effect.Actuator is used liquid, gas, electric power or other energy and converts it into driving effect by motor, cylinder or other device.
Vehicles Collected from Market electric actuator is of a great variety, and form is different.Can simply by two kinds of basic valve operation types, consider actuator.
Rotation gate: this class valve comprises: stopcock, ball valve, butterfly valve and air door or baffle plate.This class valve need to carry out with the moment requiring the actuator of 90 degree rotary manipulations
Many turning valves: this class valve can be non-rotary lifting formula valve rod or rotate non-lifting type bar, or perhaps they need turn to operate more and go to drive valve to the position opening or closing.This class valve comprises: throughway valve (stop valve), gate valve, knife gate valve etc.As a kind of selection, straight line output pneumatic or surge cylinder or diaphragm actuator also can drive above-mentioned valve.
Power-actuated many rotary types actuator is one of the most frequently used, the most reliable actuator type.Use single-phase or three phase motor actuation gear or the last actuate valve stem nut of worm and gear, Stem Mut makes valve rod generation motion make valve open or cut out.Many rotary electrics actuator can fast driving large scale valve.Major defect is, when power failure, valve can only remain on original position, only has use standby power system, and valve could be realized failure safe position (fault is opened or fail close).On market, a lot of electric actuator reaction velocitys are slow, and actuation time is long.
Model utility content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of thermostat valve link gearing, by the improvement to link transmission part in actuator, come realization response speed fast, loss is little, more accurately control steam flow, reach the more stable object of heat exchanger water outlet.
To achieve these goals, the utility model is to realize by the following technical solutions: thermostat valve link gearing, comprise valve body, piston, valve gap, lower link, the second connecting plate, upper connecting rod, the first connecting plate, coupling shaft, Cock screw and final controlling element, valve body top is provided with valve gap, valve inner is provided with piston, piston is fixed by lower link and second connecting plate one end, the second connecting plate the other end and upper connecting rod are fixed, upper connecting rod is connected with coupling shaft with Cock screw by the first connecting plate, and coupling shaft is connected with final controlling element.
According to above-mentioned thermostat valve link gearing, wherein, the support side of described lower link and upper connecting rod is provided with scale plate.
The utility model, by the improvement to link transmission part in actuator, comes realization response speed fast, and loss is little, more accurately controls steam flow, reaches the more stable object of heat exchanger water outlet.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: thermostat valve link gearing, comprise valve body 1, piston 2, valve gap 3, lower link 4, the second connecting plate 5, upper connecting rod 6, the first connecting plate 7, coupling shaft 8, Cock screw 9 and final controlling element 10, valve body 1 top is provided with valve gap 3, valve body 1 inside is provided with piston 2, piston 2 is fixed by lower link 4 and second connecting plate 5 one end, second connecting plate 5 the other ends and upper connecting rod 6 are fixing, upper connecting rod 6 is connected with coupling shaft 8 with Cock screw 9 by the first connecting plate 7, and coupling shaft 8 is connected with final controlling element 10.
It should be noted that described lower link 4 and the support side of upper connecting rod 6 are provided with scale plate 11.
This embodiment is for installing fixed drive motor (final controlling element 10), coupling shaft of supporting making; For realizing link transmission, between coupling shaft 8 and upper connecting rod 6, make a connecting plate; After upper connecting rod 6 is fixing by another connecting plate with lower link 4, integral body can knee-action, and lower link 4 can swing; Lower link 4 ends and piston rod are fixed; Link gearing material adopts stainless steel; Connecting rod rack side makes a scale plate, shows valve opening.
This embodiment, by above technological scheme, can realize:
While 1, moving between drive motor 0-90 degree, coupling shaft rotates, thereby drivening rod and piston knee-action are realized the switch of valve.
2, by scale plate, can observe the aperture of valve.
3, adopt the jointed gear unit loss of stainless steel little, wear-resistant, can frequent movement;
4, this device moment is little, and stroke is short, and drive motor only need to exchange 24V power supply, energy-saving and cost-reducing.
This embodiment, by the improvement to link transmission part in actuator, comes realization response speed fast, and loss is little, more accurately controls steam flow, reaches the more stable object of heat exchanger water outlet.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
