The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of negative pressure water temperature machine is provided, and good stability is safe and reliable.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of negative pressure water temperature machine, described negative pressure water temperature machine is based on cold water closed circuit, described cold water closed circuit comprises the water tank, magnetic valve, temperature controlling instruments, circulating pump and the heater that are communicated with successively by pipeline, the output of heater connects the input of water tank, and water tank is provided with the water supplement port for supplementing cold water.
Further, between described magnetic valve and temperature controlling instruments, set gradually air switch, tempilstick and ball valve.
Further, described air switch is made up of magnetic valve.
Further, between described temperature controlling instruments and circulating pump, be disposed with y-type filter, ball valve, Pressure gauge and tempilstick.
One pressure switch is set between described circulating pump and heater.
One discharge outlet is set between described tempilstick and Pressure gauge, and described discharge outlet is by ball valve control.
The bottom of described water tank is connected with discharge outlet, and a ball valve is set between water tank and discharge outlet.
Between described water tank and water supplement port, set gradually a magnetic valve, y-type filter.
One liquid-level switch is set in described water tank.

Compared with prior art, the beneficial effects of the utility model are: cold water closed circuit comprises the water tank, magnetic valve, temperature controlling instruments, circulating pump and the heater that are communicated with successively by pipeline, can make like this pressure of circulating water of water temperature machine the inside always little than atmospheric pressure, form negative pressure water temperature machine; Because form negative pressure water temperature machine, so avoided the phenomenon of lack of water in water temperature machine completely, make water temperature machine safe and reliable, stability is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of negative pressure oil temperature machine.
Detailed description of the invention
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, to technical characterictic of the present utility model and advantage are interpretated more in-depth.
Structural representation of the present utility model as shown in Figure 1, a kind of negative pressure water temperature machine, described negative pressure water temperature machine is based on cold water closed circuit, described cold water closed circuit comprises the water tank, magnetic valve, temperature controlling instruments, circulating pump and the heater that are communicated with successively by pipeline, the output of heater connects the input of water tank, and water tank is provided with the water supplement port for supplementing cold water.
Further, between described magnetic valve and temperature controlling instruments, set gradually air switch, tempilstick and ball valve.
Further, described air switch is made up of magnetic valve.
Further, between described temperature controlling instruments and circulating pump, be disposed with y-type filter, ball valve, Pressure gauge and tempilstick.
One pressure switch is set between described circulating pump and heater.
One discharge outlet is set between described tempilstick and Pressure gauge, and described discharge outlet is by ball valve control.
The bottom of described water tank is connected with discharge outlet, and a ball valve is set between water tank and discharge outlet.
Between described water tank and water supplement port, set gradually a magnetic valve, y-type filter.
One liquid-level switch is set in described water tank.
Described temperature controlling instruments is temperature controller.
Workflow of the present utility model is as follows: because top one side of water tank is provided with water inlet, and in the time not intaking, closed electromagnetic valve, when water inlet, magnetic valve is opened.In order better to protect water tank and magnetic valve, a y-type filter is set between magnetic valve and water inlet, for the impurity of filtered water.In the time of moisturizing, in water tank a liquid-level switch is set, can better supplementing water, prevent lack of water.
Cold water closed circuit comprises the water tank, magnetic valve, temperature controlling instruments, circulating pump and the heater that are communicated with successively by pipeline, so the water of water tank flows to temperature controlling instruments by magnetic valve, temperature controlling instruments is generally made up of temperature controller, for controlling the temperature of water of cold water closed circuit.Between magnetic valve and temperature controlling instruments, set gradually air switch, tempilstick and ball valve.Air switch is for adjusting the air pressure of negative pressure water temperature machine, and tempilstick is for the temperature of test loop.
Between temperature controlling instruments and circulating pump, be disposed with y-type filter, ball valve, Pressure gauge and tempilstick, y-type filter is mainly for the impurity in further filtered water, avoids impurity to impact to follow-up circulating pump, heater.Pressure gauge is for the pressure pressure situation of measuring circuit, and it is in order further to measure temperature that tempilstick is set herein, grasps at any time the situation of temperature.
One pressure switch is set between circulating pump and heater, in order the pressure in whole loop to be adjusted according to Pressure gauge in good time.Heater heats the water in closed circuit.
The bottom of water tank is connected with discharge outlet, by the discharge of a ball valve control water.
Because the temperature of negative pressure water temperature machine is lower, pressure is also lower, so, generally select magnetic valve to control water route.
As shown in Figure 2, the utility model also can be used for oil temperature machine, can be arranged to negative pressure oil temperature machine, different from the utility model, without water supplement port is set.And water tank changes fuel tank into, be with the difference of negative pressure water temperature machine maximum, oil temperature machine replaces magnetic valve with pneumatic operated valve, because loine pressure is larger, can not use magnetic valve, can only control flowing of oil with pneumatic operated valve.
Cold water closed circuit of the present utility model can make the pressure of the circulating water inside water temperature machine always little than atmospheric pressure, forms negative pressure water temperature machine; Because form negative pressure water temperature machine, so avoided the phenomenon of lack of water in water temperature machine completely, make water temperature machine safe and reliable, stability is high.
By the technical scheme in above embodiment, the utility model is carried out to clear, complete description, obvious described embodiment is the embodiment of the utility model part, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
