Abstract

The utility model relates to a controller for a shower set, which belongs to the technical field of water-heating device and can be applied broadly to all the shower facilities. As a constant temperature and constant pressure water faucet spool, this utility model comprises a temperature adjusting mechanism, an automatic balance mechanism and a valve body. The aforesaid temperature adjusting mechanism comprises a valve rod, a collar, a spring locking screw, a spring, a top hat, a regulation worm and a regulator jacket; the aforesaid automatic balance mechanism comprises a spring compression element, a spring, a heat sensor, a water-resisting element, a connecting bush, a spool and a shell of balance valve. The temperature adjusting mechanism and automatic balance mechanism of this utility model are joined into an organic whole. This utility model is characterized in that: seal rings are set in the spool and shell of the aforesaid balance valve. This utility model can not only improve the safety performance but also ensure convenient manufacturing.

Description

Constant temperature balanced pressure water nozzle valve core

Technical field

The utility model relates to a kind of controller that is used for shower, belongs to plumbing, can be widely used in various shower sets.

Background technique

Usually, in traditional automatic balancing valve, adopt minimum Spielpassung between equilibrium valve inner core and the shell, inner core can be free to slide in the enclosure.When cold water or hot water service inefficacy, inner core moves under the effect of water flow pressure difference rapidly, hot water or cooling water inlet were closed in moment, make water outlet have only very little even do not have current to flow out fully, prevent the water temperature rapid change of using and human body is not felt well or come to harm.

But, to cross urine as this gap and can hinder being free to slide of inner core, the mistake conference is used water and is increased, and causes usage safety performance to reduce.This very little interstice coverage causes very big difficulty to production and processing.

The model utility content

Technical problem to be solved in the utility model is, provides a kind of Security higher constant temperature balanced pressure water nozzle valve core.

Technical problem to be solved in the utility model is achieved by the following technical solution: a kind of constant temperature balanced pressure water nozzle valve core, and it comprises thermoregulative mechanism, autobalance and valve body; This thermoregulative mechanism comprises valve rod, collar, spring locking nut, spring, top cap, adjusting screw rod and regulator overcoat; This autobalance comprises spring compression spare, spring, thermosensor, water-resisting piece, connecting sleeve, equilibrium valve inner core and balance valve shell; This valve body is connected into integral body with thermoregulative mechanism and autobalance; It is characterized in that, on above-mentioned equilibrium valve inner core and balance valve shell, be equipped with seal ring.

Constant temperature balanced pressure water nozzle valve core of the present utility model is on the feature base that has kept traditional spool, on automatic balancing valve inner core and shell, all increased seal ring in addition, gap between inner core and shell can suitably be strengthened, when cold water or hot water service stop suddenly, really energy complete closed current is seal ring, improved Security, and be that production and processing is convenient.

Description of drawings

Fig. 1 is the sectional view of the utility model constant temperature balanced pressure water nozzle valve core.

Embodiment

Referring to Fig. 1, a kind of constant temperature balanced pressure water nozzle valve core, it comprises the thermoregulative mechanism of being made up of valve rod 1, collar 2, spring locking nut 3, spring 4, top cap 5, adjusting screw rod 6 and regulator overcoat 7; The autobalance of forming by spring compression spare 8, spring 9, thermosensor 10, water-resisting piece 11, connecting sleeve 12, equilibrium valve inner core 13 and

balance valve shell

14,15 and they are connected into

whole valve body

18,19 and lay respectively at balance valve core 13 and

balance valve shell

14,15 on

seal ring

16,17, equilibrium valve inner core 13 can strengthen according to the size of described seal ring with the gap of

equilibrium valve shell

14,15.

In use, when cold water or hot water service stop suddenly, automatic balancing valve inner core 13 fast moving, with the opposing party's (hot water or cold water) water intake (20 or 22) moment sealing, simultaneously the seal ring 17 on the inner core tightly is pressed on the step in

shell

14 or 15, and good sealing effect has prevented that effectively current from flowing through from the gap of equilibrium valve inner core 13 and

shell

14 or 15; In addition, thermosensor 10 when cold feed stops rapid expansion, when hot water service stops, shrinking rapidly.Drive whole autobalance parts during expansion to hot water side's fast moving, moment tightly is pressed in the seal ring on the shell 16 on the step in the valve body 18, with hot water outlet 23 complete closed; Equally, under the effect of spring 9 power, make whole autobalance parts during contraction to cold water side's fast moving, moment the end face with shell 14 tightly be pressed on the end face of valve body 19, with cold water water outlet 21 complete closed.

The anti-scald constant temperature balanced pressure water nozzle valve core of safety of the present utility model is on the feature base that has kept traditional spool, on automatic balancing valve inner core and shell, all increased seal ring in addition, gap between inner core and shell can suitably be strengthened, when cold water or hot water service stop suddenly, really energy complete closed current is seal ring, improved Security, and be that production and processing is convenient.

The utility model also has some other distortion or improvement, if those skilled in the art are subjected to the change or the improvement of the conspicuous unsubstantiality that inspiration of the present utility model makes, all belongs to the protection domain of the utility model claims.
