Description
Technical field
The present invention relates to a kind of thermostat valve that automaticallyes switch and flow to according to water temperature, belong to the hot-water heating manufacturing field of equipment.
Background technique
Existing heat supply in winter, owing to adopted advanced technology such as heat meter is installed, when effectively controlling room temperature, the waste of heat energy has reduced many.But current heating systems, because still there are some defectives in historical reasons; For example the return water temperature of thermal medium is very high sometimes, and heat energy is not fully utilized, just by the defeated back boiler room of water return pipeline; Be transported to user's hot water again through the boiler room, though temperature variation is not very big, but still passes through heat meter again, this defective is unfair to the user on the one hand, also because heat energy is not fully utilized, causes heat energy waste in essence on the other hand.
Summary of the invention:
The purpose of this invention is to provide a kind of thermostat valve that automaticallyes switch and flow to according to water temperature.
Technological scheme of the present invention realizes like this, mainly comprises valve body, water outlet C, piston piece, last seal ring connects cover, reset spring, adjusting nut, thermosensitive element, continuous motion stem, and continuous motion stem on plate washer, valve pocket, valve gap, lower seal; Said valve body is the Three way type structure, comprises water inlet A, water outlet B, C: water outlet B, C stagger 90 ° on valve body: have water export in the said valve gap, the below of water export has flow inlet; Said water export is communicated with water outlet B; Flow inlet is communicated with water inlet A, and the lower end through hole of valve gap is communicated with water outlet C; Said water inlet A is connected with the water return pipeline of heat dissipation equipment, and the pipeline behind water outlet C and the heat meter is connected, and water outlet B is connected with water return pipeline to the boiler room; Said piston piece is installed in the valve gap, mainly comprises the upper-lower seal circle, continuous motion stem; There is a plate washer at the middle part on the said continuous motion stem, and continuous motion stem passes through sealing gasket and is connected cover connection movingly; Connect cover and be connected with valve gap through screw thread, valve gap is connected with valve body with screw thread through sealing gasket; Between the baffle plate of said connection cover and continuous motion stem reset spring is installed, the top of baffle plate is equipped with thermosensitive element, and the upper end of thermosensitive element is conditioned nut and withstands.
The invention has the beneficial effects as follows that the thermal medium of the higher temperature that the present invention can be flowed out heat dissipation equipment back fail heat dissipation equipment again and is reused, the backwater that temperature is lower is directly sent the boiler room back to; Device automaticallyes switch, and does not need outer power.
Description of drawings
Accompanying drawing is an overall structure schematic representation of the present invention
In the accompanying drawing, 1 valve body, 2C water outlet, 3 piston pieces, seal ring on 4,5 coupling nuts; 6 connect cover, 7 reset springs, and, 8 adjusting nuts, 9 protective caps; 10 thermosensitive elements, 11 plate washers, 12 valve pockets, 13 continuous motion stems, 14 valve gaps; 15 water inlet A, 16 water exports, 17 flow inlet, water outlet B (18), lower seal (19); A, B are in connected state among the figure; A, C are in closed condition among the figure; Water (flow) direction is shown in arrow among the figure.
Embodiment
This mode of execution is seen accompanying drawing, and the present invention mainly comprises valve body (1), water outlet C (2), piston piece (3), last seal ring (4); Coupling nut (5) connects cover (6), reset spring (7), adjusting nut (8), protective cap (9); Thermosensitive element (10), plate washer (11), valve pocket (12), continuous motion stem (13), valve gap (14); Water inlet A (15), water export (16), flow inlet (17) water outlet B (18), lower seal (19); Valve body (1) is the Three way type structure, and water outlet B (18), C (2) stagger 90 ° on valve body (1); Have water export (16) on the valve gap (14), the below of water export (16) has flow inlet (17); Water export (16) is communicated with water outlet B (18); Flow inlet (17) is communicated with water inlet A (15), and the lower end through hole of valve gap (14) is communicated with water outlet (2); Water inlet A (15) is connected with the water return pipeline of heat dissipation equipment, and the pipeline behind water outlet C (2) and the heat meter is connected, and water outlet B (18) is connected with water return pipeline to the boiler room; Piston piece (3) is installed in the valve gap (14); Piston piece (3) mainly comprises upper-lower seal circle (4), (19), continuous motion stem (13); Continuous motion stem (13) is gone up the middle part has a plate washer (11); Continuous motion stem (13) through sealing gasket with is connected cover (6) and connects movingly, connection is covered (6) and is passed through screw thread and be connected with valve gap (14), valve gap (14) passes through sealing gasket, screw thread is connected with valve body (1); Between the baffle plate (11) that connects cover (6) and continuous motion stem (13), reset spring (7) is installed, the top of baffle plate (11) is equipped with thermosensitive element (10), and the upper end of thermosensitive element (10) is conditioned nut (9) and withstands; Transfer nut (9) is connected with valve pocket (12) through screw thread; The over top of adjusting nut (9) has an elongated slot, with the compression degree of screw-driver turn elongated slot can regulate to thermosensitive element (10); The thermosensitive element of present embodiment adopts the temperature memory alloy of spring-like.The present invention is work like this, sees accompanying drawing, and the water inlet A on the valve body (1) is connected with the water return pipeline of heating equipment, and water outlet B is connected with the water return pipeline of getting back to the boiler room; Pipeline behind water outlet C and the heat meter is connected; When return water temperature was low, the thermosensitive element (10) in the valve was in contraction state; Because the elastic acting force of reset spring (7); The baffle plate (11) that promotes on the continuous motion stem (13) moves upward; And drive piston assembly (3) also moves upward; Make the seal ring (19) of piston assembly lower end block the water outlet of valve gap (14) lower end, the seal ring of upper end (4) leaves the water export (16) on the valve gap (14), the backwater of the heat dissipation equipment that flows to through water inlet A; Through the heating plant of water export (16) from water outlet B (18) inflow boiler room, the thermal medium after the raising temperature flows into heat dissipation equipment again through heat meter again; Higher when the return water temperature that heat dissipation equipment flows out, and when surpassing the setting temperature of the thermosensitive element in the valve, the thermosensitive element of spring-like (10) expands; Promote baffle plate (11) and move downward, and compression reset spring (7), continuous motion stem (13) promotes piston assembly (3) and moves downward; The seal ring of its lower end, under the effect of hydraulic pressure, the lower ending opening of the valve gap that speeds away (14); Meanwhile, last seal ring (4) blocks the water export (16) in the valve gap (14) downwards, and water outlet B (18) is closed; From the higher backwater of temperature that the A mouth flows to, fail through the lower ending opening of valve gap (14) again and get back to heat dissipation equipment; During the set temperature value of thermosensitive element, valve automaticallyes switch: B is salty newly to be opened, and C is salty newly to close in return water temperature is lower than valve, and backwater flow back into the boiler room heating again.Elongated slot on the turn adjusting nut (10), the compression degree of can regulate thermosensitive element, thereby the operating temperature value of setting thermosensitive element, enforcement of the present invention has improved user's heat energy utilization rate; Valve need not the promotion of other power sources in switch operating, practiced thrift the energy.
