Description
[technical field]
This utility model relates to bathroom field, especially a kind of constant temperature valve core.
[background technology]
Constant temperature valve core is the mixed proportion being automatically adjusted hot and cold water, enables the temperature of mixing water to be automatically held in setting temperature
The device of degree, user can adjusting water outlet temperature the most voluntarily, after temperature sets, blend coolant-temperature gage and be maintained at and set
On fixed temperature.It is advantageous in that, can avoid the water outlet that common spool causes because of intake pressure change and inflow temperature instability
The problem that temperature is sometimes hot and sometimes cold, safety scald-proof.But still having the disadvantage that of this constant temperature valve core
1, the regulating valve stem of spool uses thread to be connected with hex union, and spool water inlet easily causes thread position and slowly ties
Incrustation scale, ultimately results in regulation dumb or stuck, affects product service life；
2, hex union can form the cavity of sealing in motor process inside spool, and the air of the inside cannot be discharged
Going, cause valve rod regulation dumb, feel is poor.
Weak point based on above-mentioned constant temperature valve core, the present inventor carries out Improvement to it, by the generation having this case.
[utility model content]
In order to overcome above-mentioned weak point present in prior art, the purpose of this utility model is to provide a kind of constant temperature
Spool.
In order to reach above-mentioned purpose, this utility model uses following concrete technical scheme: constant temperature valve core, including having heat
Spool main body and the part of water water inlet, cold water inlet and mixing water outlet are arranged in the valve core rod in spool main body,
It is provided with hex union in described spool main body, between described hex union and spool main body, is provided with sealing ring, described hex union
Upper end is threaded connection with valve core rod lower end, and its lower end is provided with plug, is provided with protection bullet between described plug and hex union
Spring, is provided with the piston between described water inlet of hot water and cold water inlet, is provided with in described piston in described spool main body
For connecting water inlet of hot water, cold water inlet and the exhalant canal of mixing water outlet, it is provided with for driving in described piston
The temperature control rod that piston moves up and down, is provided with sealing ring between described piston and spool main body.
Further, hex union upper end described in the utility model is provided with internal screw thread, and its lower end is provided with for placing plug
Groove.
Further, valve core rod described in the utility model is provided with steam vent.
Further, mixing water water outlet described in the utility model is provided with base, between described base and piston
Being provided with working spring, one end of this working spring acts on piston, and the other end acts on base.
This utility model advantage compared with prior art is:
1. this utility model is arranged by hex union and sealing ring, effectively stop flowing water from hex union through valve rod with
Internal screw thread junction, will not produce incrustation scale, extends the service life of product；
2. this utility model is provided with steam vent on valve rod, and in can making spool airtight cavity, air is discharged outward, makes
Valve rod regulation is more flexible, good hand touch.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model hex union；
The utility model is described in further detail below in conjunction with the accompanying drawings.
