Description
Technical field
The present invention relates to thermostat valve fields, and in particular to a kind of double-current to temperature control valve body.
Background technique
Thermostatic control valve (i.e. thermostat valve) is mounted on the water inlet end of cooling fin, plays the role of the constant room temperature of control.
Due to inside heating and ventilating pipeline, inside pipe wall be it is smooth, water flowing freely, when open valve is closed or feed pump stops suddenly
Only, water flow can generate a pressure to valve and tube wall, mainly valve or pump, and here it is " the water hammer effects in hydraulics
It answers ".
Thermostatic control valve under the prior art has the disadvantage that on the one hand thermostat valve flow currently on the market can not
It adjusts, there is no buffer function to water hammer effect, valve body water (flow) direction is irreversible, is not two-way；Since tube wall is smooth, after
Under the action of inertia, waterpower is rapidly reached maximum to continuous water flow, and generates extremely strong destruction, the instant pressure that water hammer generates
Even hundreds times of tens times of Normal operating pressure in reachable pipeline, this significantly fluctuation of pressure can lead to pipe-line system
Judder or noise are generated, and Valve joint may be destroyed, there is very big destruction to heating and ventilating pipeline system；Another party
Face, when valve is inversely installed, rubber sheet gasket will directly bear the active force of hydraulic pressure, when the pressure of water reached with tension force of spring
To when dynamic equilibrium, vibration frequency is close to or up to the intrinsic frequency of pipeline, causes the resonance of pipeline, generates noise, time one
Long then destructive damage.
