Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described further.Below example in heating power expansion valve as an example, but the design of model utility can be applied to other suitable valve, therefore, valve of the present utility model is not limited to heating power expansion valve.
As shown in fig. 1, comprise valve body 12, be arranged on the spring 11 in this valve body 12 according to heating power expansion valve of the present utility model; And the controlling mechanism 30 that is connected with valve body 12, this controlling mechanism 30 comprises adjusting nut 31 that contacts with spring 11 and the adjusting screw rod 35 that is connected in valve body rotationally.This valve also comprises first targeting part that is arranged on the adjusting nut, and second targeting part that cooperates with first targeting part.
As shown in figure Fig. 2, described first targeting part is arranged on the prismatic surface on the adjusting nut 31, and described second targeting part is arranged at least a portion of prismatic surface on the inwall of controlling mechanism housing of described controlling mechanism, that match with prismatic surface on the nut.In Fig. 2, cooperate with a part (bight) as the prism-shaped surface of guiding groove 39 as the bight of the adjusting nut of projection 38 hexagonal prism structure.
Described first targeting part and second targeting part can be any suitable shapes, rotate as long as can prevent adjusting nut 21.For example, adjusting nut 21 can have non-circular cross section, and second targeting part can have corresponding shape.
Described controlling mechanism 30 comprises the controlling mechanism housing, this controlling mechanism housing is fixedlyed connected with valve body 12, the connected element 32 of the controlling mechanism housing of described controlling mechanism is connected with valve body, adjusting screw rod 35 is connected with valve body 12 rotationally by this connected element 32, and adjusting nut 31 is arranged in the inner space of connected element 32.In addition, adjusting screw rod 35 can directly be connected with valve body 12 rotationally.
By six guiding grooves adjusting nut is carried out leading role.Adjusting nut and adjusting screw rod are by being threaded.When rotating adjusting screw rod, screw thread drives adjusting nut and is moved, and adjusting nut is owing to be subjected to the constraint of guiding groove, can not rotate, can only move up and down vertically, the decrement of Regulation spring, thus reach the purpose of the static degree of superheat of stable regulation heating power expansion valve.
In addition, design and installation location collar 33 is used for fixing adjusting screw rod 35 between adjusting screw rod 35 and connected element 32, makes it moving axially in valve body can not be taken place when regulating.
In addition, jump ring 36 can be used for limiting the moving range that adjusting nut 31 makes progress.Seal ring 34 is used for sealing between connected element 32 and adjusting screw rod 35.
It is the novel restriction that also realizes of this use to the degree of tightness regulation range of spring, when adjusting nut during to adjusted, the extreme higher position of the jump ring 36 restriction adjusting nuts on connected element, it is the tightest position of spring, when adjusting nut is regulated downwards, the extreme lower position of the end face 37 restriction adjusting nuts of connected element inside, the i.e. the most loose position of spring.
Describe below among second embodiment shown in Fig. 3 of the present invention and 4, no longer be described with the structure of similar among above-mentioned first embodiment.In second embodiment shown in Fig. 3 and 4, design has guiding groove 39 on valve body 12.Promptly second targeting part is the guiding groove 39 that designs on valve body.First targeting part is arranged on the projection 38 on the adjusting nut 31.
By above-mentioned mode of execution of the present utility model, heating power expansion valve of the present utility model can be by the leading role of the realization of the guiding groove on the valve body to adjusting nut, make it move up and down Shi Buhui generation axial rotation, thereby realize the stable regulation of the static degree of superheat.In addition, existing scheme adjusting screw rod is axially having only unidirectional location, and adjusting screw rod has the risk that upwards moves.Present design is provided with the location collar between adjusting screw rod and connected element, can prevent that adjusting screw rod from moving axially in using.
