Description
Technical field
It the utility model is related to one kind and be used for the self balancing antiscale constant temperature valve core of hot and cold water.
Background technology
At present, common constant temperature valve core is not due to taking real effective anti-scaling measures, so that valve element is influenceed by incrustation scale
Cause service life serious curtailment, if if effective anti-scaling measures being used, common constant temperature valve core service life can be made significantly to prolong
It is long.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of antiscale constant temperature valve core.Especially make main activities part with
Separated between incrustation scale, so as to significantly extend constant temperature valve core service life.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of antiscale constant temperature valve core, including stream
Road body, body is adjusted, temperature-sensitive spring, piston, adjusting rod, adjustment cap, spring is adjusted, takes over a business, top pull pin, pin wall sealing ring, partition wall, body wall
Sealing ring, fill in road sealing ring；It is characterized in that：A kind of described antiscale constant temperature valve core, passes through partition wall using top pull pin and is pushing up
Draw pin and partition wall side to implement sealing using pin wall sealing ring, make the elastic force of regulation spring same with thimble push-and-pull piston by taking over a business
When, the adjusting rod of partition wall side, regulation spring, adjustment cap and incrustation scale are separated；Runner in runner body Yu piston corresponding position
Two-way step is respectively set on body and piston and sealing ring is set on two-way step to support piston both ends and barrier piston and stream
Road body movement face does not contact with incrustation scale；Sealing ring is set between regulation body and partition wall.Described top pull pin is connected using screw rod
Piston simultaneously stops that temperature-sensitive spring and regulation spring both ends form to piston and pull structure by both ends nut shim.
The utility model compared with prior art, has the advantages that：Due to using anti-scaling measures, making constant temperature valve core
Main activities part separated with incrustation scale, so as to significantly extend constant temperature valve core service life, avoid thermostatic valve industry length
Maximum drawback-scale hazard existing for phase.
Brief description of the drawings
Fig. 1 is that a kind of antiscale constant temperature valve core of the utility model embodiment 1 uses thimble structure main sectional view.
Fig. 2 is that a kind of antiscale constant temperature valve core of the utility model embodiment 2 uses Tiebar structure main sectional view.
Specific implementation method
Embodiment 1：Referring to Fig. 1, the present embodiment mainly includes runner body 1, temperature-sensitive spring 2, piston 3, fills in road sealing ring 4, pin
Wall sealing ring 5, partition wall 6, body wall sealing ring 7, body 8 is adjusted, adjustment cap 9, top pull pin 10, takes over a business 11, adjusts spring 12, adjusting rod
13。
The present embodiment, which turns adjusting rod 13, to be made to be arranged on the tune with screw thread being connected in the regulation hexagon ring of body 8 and with adjusting rod 13
Section cap 9 is axially moveable, so as to be arranged on adjustment cap 9 by the promotion of adjustment cap 9 and take over a business the regulation spring 12 between 11, then by adjusting
The top pressure of spring 12 takes over a business 11, then is promoted piston 3 mobile to cold water side from taking over a business 11 by top pull pin 10 and compressed temperature-sensitive spring 2, and then
Water temperature is reduced to preset leaving water temperature.When upstream, water pressure fluctuations cause the leaving water temperature to change, by temperature-sensitive spring 2 and regulation spring 12
Piston 3 is mutually promoted to realize that automatic synchronization adjusts cold and hot water flow passage size to stablize leaving water temperature.In the present embodiment current with
Erosion of the incrustation scale to movable part is avoided using hermetic barrier mode between main activities part：Set between regulation body 8 and partition wall 6
Put body wall sealing ring 7 and implement static seal, set pin wall sealing ring 5 to implement dynamic sealing in the side of partition wall 6 and top pull pin 10, flowing
With setting two-way step on the runner body 1 and piston 3 of the correspondence position of piston 3 respectively and diaphragm respectively being set on step in road body 1
Formula movable sealing structure is to avoid between runner body 1 and piston 3 place of being mutually shifted from gathering incrustation scale.
Embodiment 2：Referring to Fig. 2, the present embodiment mainly includes runner body 14, temperature-sensitive spring 15, piston 16, fills in road sealing ring
17, pin wall sealing ring 18, partition wall 19, body wall sealing ring 20, body 21 is adjusted, adjustment cap 22, pull bar 23, pulling plate 24, adjusts spring 25,
Adjusting rod 26.The present embodiment operation principle and basic structure are substantially the same manner as Example 1.The main distinction is：The present embodiment will
Temperature-sensitive spring 2 and regulation spring 12 are changed to the temperature-sensitive spring 15 of the present embodiment by top pull pin 10 to the pushing tow mode of piston 3 in embodiment 1
It is connected with regulation spring 25 by pulling plate 24 and pull bar 23 by screw thread with piston 16 and piston 16 is pulled, so as to cold and hot
Water flow passage position, which is realized, to be exchanged.
Although the utility model is disclosed as above in the form of embodiment, it is not limited to protection of the present utility model
Scope, for example, cancel text described in seal ring part and implementation section seal area every or change sealing loop-shaped implementation of class like close
Seal structure.In a word, any technical staff for being familiar with this technology, do not departing from what is made in spirit and scope of the present utility model
Change and retouch, the scope of protection of the utility model all should be belonged to.
