Abstract
The utility model provides a pressure controller capable of adjusting a pressure setting point from the outside. The controller comprises a shell, a pressure sensing device, a push rod, a microswitch and a top cover. The push rod is connected to one end of a connecting rod assembly through an articulated component. The other end of the connecting rod assembly is connected to a tension spring. An external portion of the shell is provided with a mediation seat and a mediation nut. The mediation seat is provided with a pull bar. The pull bar is arranged in the shell. One end of the pull bar is connected to the other end of the tension spring. The structure is simple and usage is convenient. Through the above structure design, the pressure controller can adjust the pressure setting point on an external portion on site and a pressure adjustment device does not need to be used. In addition, adjustment and calibration of the pressure setting point can be performed under the condition that gas tightness of the pressure controller is not obstructed (such as underwater) so that usage performance of the pressure controller is greatly increased.
Description
Technical field
The utility model relates to pressure checking device field, and relating in particular to can the outside pressure controller of adjusting pressure set-point.
background technology
The inner half of pressure controller comprises push rod, adjusts bolt and spring, pressure controller in actual use, can compress or releasing spring by turning adjustment bolt, thereby increase or reduce to promote push rod and complete the force value that triggers displacement L, namely corresponding pressure medium P value, and the namely pressure set-point of pressure controller of this predefined P value.Be positioned at the inside of switch case owing to adjusting bolt, must open pressure controller lid and regulate so want to adjust pressure set-point.Generally, before dispatching from the factory, just first pressure set-point is mixed up, but in actual use, when pressure controller installs to behind scene, also there is the situation that need to readjust pressure set-point, also having certain situation is the occasion that does not allow to open lid, therefore just cannot adjust the pressure set-point of pressure controller.
summary of the invention
The utility model is the shortcoming that the above-mentioned existing pressure controller of mentioning of solution cannot regulate the force value of setting in the situation that not opening top cover, and a kind of pressure controller that can adjust from outside pressure set-point is provided.
Concrete, the utility model provides a kind of pressure controller that can adjust from outside pressure set-point, it comprises housing, inductor, push rod, microswitch and top cover, described push rod is connected with one end of link assembly by articulated elements, the other end of described link assembly is connected with extension spring, and the outer setting of described housing has the seat of conciliation and reconciles nut, and described conciliation seat is provided with pull bar, described pull bar is arranged on the inside of described housing, and one end of described pull bar connects the other end of described extension spring.
Preferably, below described pull bar, be fixedly installed and be useful on the rule that shows extension spring deformation values.
Preferably, on described rule, be provided with pointer, shown in pointer be arranged on the side of described pull bar.
Preferably, described top cover and described rule for position be provided with and see the form of checking.
The utility model is simple in structure, easy to use.By above structural design, can make pressure controller just can carry out in outside at the scene pressure set-point adjustment, and without by pressure adjustment assembly.Can under the bubble-tight condition that does not hinder pressure controller, (for example under water) carry out the adjustment of pressure set-point in addition, this has all promoted the usability of pressure controller greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further explained.
As shown in Figure 1, a kind of pressure controller that can adjust from outside pressure set-point, it comprises housing 1, inductor 2, push rod 3, microswitch 4 and top cover 5, push rod 3 is connected with one end of link assembly 6 by articulated elements 60, the other end of link assembly 6 is connected with extension spring 7, and the outer setting of housing 1 has the seat of conciliation 8 and reconciles nut 9, reconciles seat 8 and is provided with pull bar 10, pull bar 10 is arranged on the inside of housing 1, and one end of pull bar 10 connects the other end of extension spring 7.
Preferably, below pull bar 10, be fixedly installed and be useful on the rule 11 that shows extension spring 7 deformation values.
Preferably, on rule 11, be provided with pointer 12.
Preferably, top cover 5 and rule 11 for position be provided with and see the form 13 of checking.
Below in conjunction with Fig. 1, principle of work of the present utility model is further explained:
Push rod 3 is moved up and is promoted the right half part of link assembly 6 to top offset by inductor 2, and extension spring 7 simultaneously will produce reacting force, and in the time that displacement reaches triggering displacement L, the pulling force of left side extension spring 7 is also a determined value.Because the elasticity linearity of extension spring 7 is fine, so the deformation values of extension spring 7 is passed through the link assembly 6 of rigidity, according to lever principle, corresponding pressure setting point value P is also linear, so can obtain pressure setting point value by the deformation values of measuring extension spring 7.
In housing 1 upper left corner Position Design regulating device, setting nut 9 is in the outside of housing 1, pull bar 10 is housed in adjustment seat 8, pull bar 10 is connected with one end of extension spring 7, pointer 12 is housed near the lower end of pull bar 10, below pull bar, fix rule 11, the deformation values of the extension spring 7 showing on rule 11 is just corresponding corresponding pressure setting point value, on top cover 5, a form 13 is offered in the position of corresponding rule 11, assemble tight in the situation that at pressure controller, in outside by turning setting nut 9, up or down when adjusting yoke 10 position, pressure setting point value on the rule 11 that observation pointer 12 is indicated, just reach the object that regulates pressure set-point.
The utility model is simple in structure, easy to use.By above structural design, can make pressure controller just can carry out in outside at the scene pressure set-point adjustment, and without by pressure adjustment assembly.Can under the bubble-tight condition that does not hinder pressure controller, (for example under water) carry out the adjustment of pressure set-point in addition, this has all promoted the usability of pressure controller greatly.
Person of ordinary skill in the field is to be understood that: in the situation that not departing from ultimate principle of the present invention; can carry out various amendments, retouching, combination to the present invention, supplement or the replacement of technical characterictic, these are equal to substitute mode or within obviously mode of texturing all falls into protection scope of the present invention.
