Technical field
The utility model relates to the temperature control device technical field, relates in particular to a kind of thermostat valve system with the hard sealing of interface.
Background technique
Heat-operated valve; Be called for short thermostat valve; Be the typical application of flow control valve in domain of control temperature, its basic principle is with heat, cool equipment, hot (cold) matchmaker inlet flow rate once, to reach the control apparatus outlet temperature through control heat exchanger, air-conditioning unit or other.When load changes, regulate flow through changing valve opening degree, to eliminate the influence that fluctuation of load causes, make temperature return to setting value.
The interface of thermostat valve of the prior art is EPDM or the soft seal of NBR rubber pad, is corroded easily, and working life is shorter, causes reliability low, and maintenance cost is high.
The model utility content
The purpose of the utility model is to design a kind of novel thermostat valve system with the hard sealing of interface, addresses the above problem.
To achieve these goals, the technological scheme of the utility model employing is following:
A kind of thermostat valve system with the hard sealing of interface; Comprise valve body and connecting tube, said valve body comprises feed-water end, waterexit end and spool end, said feed-water end and the coaxial setting in said waterexit end; Said spool end is perpendicular to said feed-water end setting; Be respectively equipped with intake pipe, outlet pipe and spool cavity on said feed-water end, said waterexit end and the said spool end, said intake pipe is communicated with said outlet pipe through said spool cavity, and said intake pipe is communicated with said connecting tube; One end stuffing box gland of said connecting tube is located in the said intake pipe.
Said intake pipe is provided with the intake pipe sealing surface, and the corresponding position of said connecting tube is provided with the connecting tube sealing surface, and said intake pipe sealing surface matches with said connecting tube sealing surface, and said connecting tube sealing surface compact is on said intake pipe sealing surface.
Said intake pipe is provided with the matrix draw-in groove; Correspondence is provided with convex Ka Tai on the said connecting tube; Said matrix draw-in groove matches with said convex Ka Tai, said convex card decometer be connected in the said matrix draw-in groove and with said connecting tube sealing surface compact on said intake pipe sealing surface.
The center line of said spool cavity is perpendicular to the runner center line of said intake pipe, and the runner center line of said outlet pipe and the center line of said spool cavity acutangulate setting.
The runner center line of the runner center line of said intake pipe, said outlet pipe and the center line of said spool cavity are positioned on the plane.
The runner center line of said outlet pipe becomes 30 ° of angles to be provided with the center line of said spool cavity.
Said waterexit end and said spool end directly are provided with stiffening rib.
The beneficial effect of the utility model can be summed up as follows:
1, the utility model replaces flexible sealing of the prior art with rigid sealing, has avoided the problem that soft seals such as EPDM or NBR rubber pad in use are corroded easily, working life is short, has improved the reliability of system, has reduced maintenance cost.
2, the utility model is simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
