Abstract
The utility model relates to a valve. The valve comprises a valve body, a piston cylinder body, a compression bar, a driving device and a piston assembly. A water outlet is formed in the lower portion of the valve body, and the water outlet in the valve body is matched with the piston assembly. The top end of the compression bar is connected with the driving device, the compression bar penetrates through the piston cylinder body and is matched with the piston assembly, and a center hole is formed in a center shaft of the piston assembly. The compression bar is sleeved with a compressing spring between the piston assembly and the piston cylinder body, and the compression bar penetrates through the center hole and is movably connected with the piston assembly. Thus, relative displacement can occur between the compression bar and the piston assembly along the center hole. According to the valve, when a stepping motor or a temperature bulb type control mechanism is used for working, the compression bar is pressed downwards, the valve is closed, once the stepping motor or the temperature bulb type control mechanism works continuously to exert downward pressure, the compression bar can continue moving downwards, the phenomenon that the driving device is damaged due to strong counter-acting force is avoided, the service life of the driving device such as the stepping motor or the temperature bulb type control mechanism is greatly prolonged, and meanwhile mechanical machining accuracy and cost are lowered.
Description
Technical field
The utility model belongs to flow control valve, is specifically related to a kind of thermostat valve.
Background technique
The process that changes along with heat in recent years, thermostatic valve is widely used.But old thermostatic valve and electric heating valve, its structure are mostly the principles of utilizing thermometer bulb to expand with heat and contract with cold.Ambient temperature rising drive unit thermometer bulb expands, and the depression bar piston moves down, cut-off valve.After closing, if excess Temperature, thermometer bulb continues the depression bar application of force, and depression bar can not move, and to thermometer bulb, imposes very large outbreak firmly, causes the medium in thermometer bulb to overflow, and drive unit lost efficacy, and used inconvenience and high cost.In like manner, electric heating valve is also that depression bar causes diaphragm breakage to lose efficacy to the thermometer bulb interior diaphragm because of the pressure that produces that expands.
In application, the stepper motor of usining is also arranged as driving power, easy to use.Due to the stepper motor follow procedure take electromagnetic pulse as driving, mobile very accurate, but too large with the error after the valve body assembling, in case after valve closed, stepper motor also gave depression bar pressure downwards, because of reaction force, cause easily that stepper motor throws switch, the problem such as stuck, cause stepper motor to damage and lost efficacy.If improve the precision of machining assembling, cost can improve again greatly.
The model utility content
The technical problems to be solved in the utility model is, a kind of valve is provided, the depression bar of this valve is when the closed water outlet of piston assembly, depression bar can continue relative piston assembly and walk downward, regulate thus the reaction force of depression bar to drive unit, extend the working life of drive unit such as stepper motor or thermometer bulb, reduce machining accuracy and cost.
For achieving the above object, the utility model is by the following technical solutions:
A kind of valve, comprise valve body, piston/cylinder, depression bar, drive unit and piston assembly, described valve body lower portion is provided with water outlet, water outlet in described valve body coordinates with piston assembly, described depression bar top connecting drive device, passing piston/cylinder coordinates with piston assembly, described piston assembly arranges center hole, described depression bar is sheathed Compress Spring between piston assembly and piston/cylinder, and pass center hole and piston assembly and be flexibly connected, described depression bar is by Clip Reed C positioning piston assembly is set, and so, depression bar can have relative displacement along center hole and piston assembly.
Preferably, described drive unit comprises step motor type or thermometer bulb formula control mechanism, with control depression bar to down stroke or reciprocating stroke, under the drive of depression bar and Compress Spring, piston assembly coordinates realization to close or open with water outlet.
Preferably, Returnning spring and depression bar interlock are set in described piston/cylinder, when drive unit only drove depression bar to down stroke, Returnning spring drove the depression bar return.
The utility model compared with prior art has the following advantages:
1) water outlet in the utility model valve body coordinates unlatching or throttle down with piston assembly.When step motor type control or the work of other drive units, press depression bar downwards, Compress Spring pushing piston assembly throttle down, in case the drive unit continuation is given downwards and pressure, depression bar can pass piston assembly to be continued to move down, thoroughly solved the conventional ADS driving device when depression bar stops moving downward, depression bar to drive unit without buffering, the problem that can not automatically regulate the depression bar reaction force, avoid drive unit because the huge reaction force of depression bar damages, greatly extend the working life of drive unit such as stepper motor or thermometer bulb.
2) the utility model greatly reduces machining assembly precision and cost, and efficient work is stable.

Fig. 1 is structural representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
Embodiment 1
As shown in Figure 1, the present embodiment comprises valve body 1, piston/cylinder, depression bar 10, step motor type control mechanism and piston assembly 2, and described valve body 1 bottom is provided with water outlet 14, and the water outlet 14 in described valve body coordinates with piston assembly 2; Described depression bar 10 top connecting drive devices, pass piston/cylinder and the described depression bar of piston assembly 2 sheathed Compress Spring 4 between piston assembly 2 and piston/cylinder, and pass center hole, at piston assembly 2 downsides, Clip Reed C15 is set, concrete, described valve body 1 top arranges piston/cylinder, described piston/cylinder comprises piston sleeve 11 and piston cap 9, and described piston sleeve 11 and valve body 1 use are threaded.Described piston sleeve 11 and piston cap 9 inside are provided for protective cap 8, the compressing tablet 6 of Returnning spring 7 location, the corresponding depression bar 10 in the medial axis of described piston cap 9, protective cap 8, compressing tablet 6, piston sleeve 11, piston assembly 2 arranges center hole, and described depression bar passes piston cap 9, protective cap 8, Returnning spring 7, compressing tablet 6, piston sleeve 11 and piston assembly 2 successively by center hole; Clip Reed B13 is set be used to blocking Returnning spring 7 on the depression bar between described protective cap 8 and compressing tablet 6, piston sleeve 11 and piston cap 9 are established respectively to O RunddichtringO B12 and O RunddichtringO A5 with the depression bar cooperation place.
During stepper motor work, press depression bar 10 downwards, Clip Reed C15 is descending with depression bar 10, and piston assembly 2 is descending, closed water outlet under the stretching force effect of Compress Spring 4, valve closing; Stepper motor also works on, and depression bar 10 continues to move down along center hole, has solved because depression bar stops advancing stepper motor is implemented to reaction force, cause stepper motor stuck, throw switch, the problem such as damage.
When stepper motor quit work, described Returnning spring 7 band depression bars 10 are return upwards, and depression bar 10 is mentioned piston assembly 2 by Clip Reed C15, opens water outlet.
Piston assembly 2 can be the single-piece that coordinates with water outlet 14, can be also the assembly of suit fitted seal circle.
