Abstract
The invention discloses a thermostatic automatic adjusting valve for preventing instability of water pressure. The thermostatic automatic adjusting valve consists of a valve body (1), a sealing cover (2), a valve core (3), a spring (4) and a control loop (5). The thermostatic automatic adjusting valve is characterized in that: the working state of the valve core (3) is controlled by fit of the valve core (3) and the valve body (1), rigidity of the spring (4) and control loops of cold water and hot water inlet together so as to adjust the mixing proportion of cold water and hot water. According to the thermostatic automatic adjusting valve for preventing the instability of the water pressure, a water valve can quickly make a response under the condition of great change of the water pressure to ensure that the temperature of the cold water and the hot water mixed together through the water valve is not greatly changed.
Description
Technical field
The present invention relates to the unstable constant temperature automatic regulating valve of a kind of anti-hydraulic pressure, belong to field of mechanical technique.
Background technique
Water tap product about " constant temperature " has much at present, the realization of these product constant temperature functions all has precondition, the hydraulic pressure of hot water and the hydraulic pressure of cold water all can not change too big, but the ratio of China rural area and samll cities and towns is also bigger, those local hydraulic pressure are very easily unstable the water use peak phase, even in the city, hydraulic pressure also has unsettled the time.
Summary of the invention
The technical problem that solves:, the object of the present invention is to provide the unsettled constant temperature automatic regulating valve of a kind of anti-hydraulic pressure in order to solve aforesaid problems of the prior art.
Technological scheme: in order to reach the purpose of foregoing invention, the technical solution adopted in the present invention is: prevent being made up of valve body 1, sealing cover 2, spool 3, spring 4, control loop 5 at the unsettled constant temperature automatic regulating valve of hydraulic pressure; It is characterized in that: spool 3 cooperates with valve body 1, the rigidity of spring 4, and the control loop that cold water, hot water enter is controlled the mixed proportion that the working state of spool 3 is regulated hot and cold water jointly.
The unsettled constant temperature automatic regulating valve of a kind of anti-hydraulic pressure of the present invention has under the situation of bigger variation at hydraulic pressure exactly, and water valve can react rapidly, guarantees that the hot and cold water temperature that mixes by water valve does not have too big variation.
Description of drawings
Fig. 1 is the structural representation of the unstable constant temperature automatic regulating valve of anti-hydraulic pressure.
Specific embodiments
As shown in Figure 1, the unstable constant temperature automatic regulating valve of the anti-hydraulic pressure of the present invention is by valve body 1, sealing cover 2, and spool 3, spring 4, control loop 5 is formed.Import A feeds cold water, and import B feeds hot water; Outlet C, outlet B is connected with common discharge control water tap.When not having current to flow into, spool is in working position as shown in the figure under the effect of two springs, and import is unimpeded, import B closure.After import A fed cold water, spool 3 upper ends were subjected to the pressure effect of water, and spool 3 will move down.Import B is opened, and hot water enters.At first, the power that the power that spool 3 upper ends are subjected to is subjected to greater than spool 3 lower ends, spool 3 moves down always.Along with opening B increases, following end pressure constantly increases; Import A reduces, and last end pressure constantly reduces.Final spool 3 will be in a stable status.When externally condition is immovable, cold water and hot water will mix according to a certain percentage.This steady state is subjected to the influence of common discharge control water tap.If import A hydraulic pressure increases, then the flow of import A will increase, and this can cause the pressure on spool 3 tops to increase, and spool 3 is moved down.Import A will diminish, and flow diminishes, and pressure diminishes; Import B increases, and flow increases, and pressure increases.Spool 3 finally still can be got back to stable status.If the state of the water tap of common discharge control does not at this moment change, then the mixed proportion of cold water and hot water will can not change, and water temperature will can not change.Import A hydraulic pressure reduces, import B variation in water pressure and import A, situation that import B hydraulic pressure changes simultaneously and top analysis are in full accord.
The foregoing description does not limit the present invention in any form, all take to be equal to replace or technological scheme that equivalent transformation obtained, all drop in protection scope of the present invention.
Claims (1)
1. prevent forming by valve body, sealing cover, spool, spring, control loop for one kind at the unsettled constant temperature automatic regulating valve of hydraulic pressure; It is characterized in that: spool cooperates with valve body, the rigidity of spring, and the control loop that cold water, hot water enter is controlled the mixed proportion that the working state of spool is regulated hot and cold water jointly.
