Description
Technical field
The invention belongs to mechanical engineering technical field, relate to a kind of flow regulator, particularly a kind of electric heating final controlling element.
Background technique
The electric heating final controlling element is a kind of device that is used for remote control system flow, heat (cold).The electric heating final controlling element is mainly used in the floor heating heating system, the closing and opening of controlling plumbing fixtures valve; Specifically be applied on water collecting and diversifying device branch road valve, valvelet, the transient equiliblium valve.About the pertinent literature of electric heating final controlling element, like the once disclosed a kind of electric heating final controlling element of Chinese patent document [patent No.: ZL200920187875.1, notice of authorization number: CN201513624U].Though this electric heating final controlling element can be manually and the automatic opening-closing function, also exists complex structure, inconvenient problem with use.
Summary of the invention
The objective of the invention is to have the problems referred to above, proposed a kind of easy to use and safe electric heating final controlling element to existing technology.
The object of the invention can be realized through following technical proposal: a kind of electric heating final controlling element; It is characterized in that; Comprise fixed base and the base that can be connected mutually with valve body; Described fixed base internal fixation has thermometer bulb and electrical heating elements, and described electrical heating elements links to each other with the body of thermometer bulb, has to the flexible connection mechanism that is resisted against base direction mobile trend continuous all the time through an end that can make fixed base between described fixed base and the base.
Base was connected with the valve body of valve mutually when this electric heating final controlling element used, and the valve rod of valve passes base and links to each other with the push rod of thermometer bulb.Electrical heating elements links through lead and power supply, through the state of control power supply and then control electrical heating elements.The temperature-sensitive paraffin place of heating of this electrical heating elements and this heat transfer to thermometer bulb when electrical heating elements is in "on" position, temperature-sensitive paraffin expanded by heating and then promotion push rod are to this external moving, and push rod drives valve rod and moves the flow of realizing the reduction valve.If push rod drives valve rod and moves when making valve closing and electrical heating elements still be in "on" position; The body of thermometer bulb drives fixed base to moving away from the base direction; Flexible connection mechanism is compressed; Obviously flexible connection mechanism has effectively played protective action, has improved Security and working life that this electric heating final controlling element uses.After electrical heating elements switches to off-position by "on" position; Temperature-sensitive paraffin in the thermometer bulb reduces with room temperature gradually; Fixed base is resisted against on the base under the effect of flexible connection mechanism gradually; Can be contracted to gradually in the thermometer bulb body under the action of reset spring of push rod in valve, and then the flow of valve increases gradually.
In above-mentioned electric heating final controlling element, be provided with pad between described fixed base and the base.
In above-mentioned electric heating final controlling element, described electrical heating elements is the PTC thermistor of disk shape, and the end face of described PTC thermistor and body leans.The PTC thermistor is a positive temperature coefficient thermistor, and its resistance value is along with the rising of PTC thermistor body temperature demonstrates the increase of step evolution, and temperature is high more, and resistance value is big more.The PTC thermistor has that sensitivity is higher, operating temperature range is wide, volume is little, easy to use, be prone to shape, advantage such as good stability, overload capacity are strong, so this electric heating final controlling element also has the advantage of the stable and long service life of usability except that the advantage that the PTC thermistor self has.
In above-mentioned electric heating final controlling element, described electrical heating elements is the electric heating wire that is positioned on the body outer side surface of thermometer bulb.
In above-mentioned electric heating final controlling element, described fixed base is cylindric, and described electrical heating elements and thermometer bulb are positioned at the center of fixed base; Described fixed base lateral part has two pilot holes that axially connect at least, all is equipped with a directional post in each described pilot hole, and an end of described directional post is connected with base mutually.Directional post is circumferentially fixing with fixed base, but fixed base can move axially and fixed base has the high advantage of stability of motions along directional post.
In above-mentioned electric heating final controlling element, described flexible connection mechanism comprise be fixedly connected on directional post the other end place spring seat be set in the spring on the fixed base, described spring one end is resisted against on the spring seat, the other end is resisted against on the fixed base.Above-mentioned directional post also links to each other base with spring seat, spring is between base and spring seat, and spring seat spring provides the portion of putting forth effort and limited the movement travel of fixed base.Under the situation that the thermometer bulb push rod does not stress, must be resisted against on the base at an end of the elastic force effect lower fixed seat of spring, and spring is compressed simultaneously when fixed base moves.
In above-mentioned electric heating final controlling element, have on the described spring seat and directional post positioning hole one to one, the other end of described directional post passes positioning hole; Outer rim place, described directional post the other end has the flange of outside protrusion, and center, described directional post the other end has draw-in groove, is provided with chock in the described draw-in groove, and the bottom surface of described flange and the end face of spring seat lean.
In above-mentioned electric heating final controlling element, have on the described spring seat and directional post positioning hole one to one, the described directional post the other end passes positioning hole; Place, described directional post the other end has buckle, and the bottom surface of described buckle and the end face of spring seat lean.
In above-mentioned electric heating final controlling element, described fixed base one end inwall is provided with annular recessed shoulder, has annular convex shoulder on the described thermometer bulb body, and the end face of described annular convex shoulder is resisted against on the annular recessed shoulder bottom surface.
In above-mentioned electric heating final controlling element, be fixed with housing on the described base, described spring, fixed base and spring seat all are positioned at housing.
In above-mentioned electric heating final controlling element; Described in above-mentioned electric heating final controlling element; The other end of described fixed base is fixed with connecting base, is fixed with cover plate on the described connecting base, and described case top has and the equal resigning hole one to one of cover plate position and structure.
