Abstract
The utility model provides a temperature control valve which comprises a valve body, a valve stem and a valve spool. The valve stem and the valve spool are arranged in the valve body. The temperature control valve is characterized in that the lower end of the valve stem is connected with the valve spool by draw bars, a temperature sensing device is disposed at the upper end of the valve stem, a temperature sensing medium is filled in the temperature sensing device, a spring assembly A and a spring assembly B are respectively arranged at joints of the valve stem and the draw bars and a joint of the valve stem and the temperature sensing device, the valve body is further provided with a hot fluid inlet, a cold fluid inlet and a fluid outlet, and the fluid outlet is arranged at one end of the temperature sensing device in the valve body. The temperature sensing medium is paraffin which is a heat-sensitive material, and is high in temperature sensitivity, and the opening of the valve spool can be quickly adjusted. In addition, owing to the spring assembly A and the spring assembly B, reverse acting force opposite to expansive force of the temperature sensing medium can be provided for the valve stem, the valve spool can keep balanced, the opening of the valve spool is adjusted when the temperature of fluid changes, and normal running of the valve is guaranteed. Besides, the temperature control valve is unique in structure, reliable in temperature control and wide in application prospect, and does not need to be driven by external force.
Description
Technical field
The present invention relates to valve technology field, relate in particular to a kind of thermostat valve.
Background technique
Thermostat valve is a kind of full automatic fluid temperature (F.T.) and flow control device, its effect is to pass into respectively valve pocket when two different fluids of temperature, automatically regulate both flows by the thermostat valve internals, make outlet temperature keep constant, drive and control gear and need not to add.As a kind of novel valve, thermostat valve is increasingly extensive in the application of China, and the bearing lubrication cooling system and other convection cells that are mainly used in the large-scale high speed rotary unit such as power station generator combination Systems of Centrifugal Compressor Unit have in the system of temperature control requirement.
Chinese patent ZL 200920116279.4 discloses a kind of thermostat valve, it is characterized in that: spool comprises tubular housing and the heat sensitive wax that is positioned at housing, and an end of push rod penetrates housing and heat sensitive wax leans, and the other end is resisted against on top cover.Although this patent is simple in structure, temperature control sensitivity is relatively poor, automaticity is not high.
So, to be badly in need of at present a kind of simple in structurely, moisture sensitivity is high, and automaticity is high, is beneficial to the temp controller with heat sensitive material of promoting on a large scale.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of thermostat valve, comprise valve body, be arranged on valve rod and spool in valve body, it is characterized in that: the valve rod lower end is connected with spool by pull bar, the upper end arranges a temperature sensing device, temperature sensing medium is filled in temperature sensing device, at valve rod and pull bar, valve rod and temperature sensing device joint, cluster spring A and cluster spring B are set respectively, described valve body also offers hot fluid import, cold fluid import and fluid output, and fluid output is opened in temperature sensing device one end in valve body.
Described temperature sensing medium adopts heat sensitive material paraffin.
The beneficial effects of the utility model are: adopt paraffin to make temperature sensing medium, moisture sensitivity is high, can be rapidly effect regulating spool aperture by valve rod and pull bar; The existence of cluster spring A and cluster spring B can provide a backward-acting power opposite with the temperature sensing medium expansive force to valve rod, the equilibrium position that can keep spool, and adjust the aperture of spool when fluid temperature (F.T.) changes, guarantee the normal operation of valve.A kind of thermostat valve that the utility model provides, structure is unique, temperature control is reliable, need not external force drives, and has a extensive future.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further explained explanation, as figure, 1-valve body, 2-spool, 3-valve rod, 4-pull bar, 5-temperature sensing device, 6-temperature sensing medium, 7-spring A, 8-spring B, the import of 9-hot fluid, the import of 10-cold fluid, 11-fluid output.
Embodiment
As shown in Figure 1, at interior valve rod 3 and the spool 2 of arranging of valve body 1, valve rod 3 lower ends are connected with spool 2 by pull bar 4, the upper end arranges a temperature sensing device 5, at the interior filling temperature sensing medium 6 of temperature sensing device 5, at valve rod and pull bar, valve rod and temperature sensing device joint, cluster spring A7 and cluster spring B8 are set respectively, described valve body 1 also offers hot fluid import 9, cold fluid import 10 and fluid output 11, and fluid output 11 is opened in interior temperature sensing device 5 one ends of valve body 1.
In concrete using process, thermostat valve be initially in cold fluid import 10 closed conditions, at first hot fluid is entered in valve body 1 by hot fluid import 9, make temperature sensing medium 6 expanded by heating, promoting valve rod 3 and pull bar 4 moves downward, cold fluid import 10 is opened, and cold fluid enters to mix with hot fluid in valve body 1 by fluid output 11 and flows out.Constantly move because temperature variation makes valve rod 3 and pull bar 4, regulate the flow of cold fluid and hot fluid, until reach predetermined temperature.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
