Abstract
The utility model provides a new structure of a pressure controller. The utility model is characterized in that an adjusting device is arranged under a hollow cavity of a pipe joint and a dish-shaped film; the adjusting device comprises an adjusting spring and an adjusting screw; the mechanical characteristics of the dish-shaped film are changed to meet various requirements in an adjusting mode, and the mechanical characteristics of the dish-shaped film are not controlled by traditional material selection and special fabrication process; accordingly, the fabrication cost of the utility model is reduced, and simultaneously, the control precision is increased; the application range of the utility model is enlarged. The adjusting device is provided with a simple and reliable locking device in order to ensure that a set value of the pressure controller is constant.
Description
The utility model relates to a kind of control means of hydrodynamic pressure, and particularly a kind of sensor is the fluid force control means of the reelability member of bowing to pressure.
In cooler compressor; pressure controller is the main devices of its high low pressure protection; the 20PS series pressure controller of TIX; it is the more advanced product of technology in the like product; it adopts disc-shaped diaphragm as elastic sensing element; when signal pressure reaches setting value; the disc-shaped diaphragm unstability produces kick; thereby actuating spring action; the contact is disconnected or connection; thereby reach the control purpose; this product is to rely on the material of disc-shaped diaphragm and manufacturing process to realize the required mechanical characteristic of pressure controller diaphragm; and satisfy the complete machine characteristic of product according to this; but the mechanical characteristic of disc-shaped diaphragm is subjected to its material; the material uniformity; hardness; all multifactor influences such as the uniformity of thickness and thickness distribution and shape; as require to satisfy predetermined properties; then in selection and manufacture process; must pay big cost; thereby increase the manufacture cost of product greatly; simultaneously; because the problems referred to above; can change the characteristic of disc-shaped diaphragm with follow-up welding process, make it be difficult to make high precision membranes, thereby limited the using scope of this product.
The purpose of this utility model is that a kind of pressure controller new structure will be provided, and it not only improves manufacturing process, reduces manufacture cost, and can enlarge its Applicable scope.
The utility model is achieved in that the regulating device of establishing an adjustment disc-shaped diaphragm mechanical characteristic below the pipe joint hollow cavity of pressure controller and disc-shaped diaphragm, it is the spinodal decomposition point that utilizes the active force change disc-shaped diaphragm of regulating device, use according to the different needs of control or different original mechanical characteristic of disc-shaped diaphragm, reach the purpose of adjusting set point in the adjustment mode.
Regulating device is made up of spring and adjustment screw, and is provided with reliable locking measure.
The utility model has adopted a simple and reliable regulating device; the mechanical characteristic of disc-shaped diaphragm is done the change of various needs in the adjustment mode; rather than rely on traditional selection and special fabrication processes to control the disc-shaped diaphragm mechanical characteristic; thereby reduced the manufacture cost of pressure controller significantly; utilize its adjustable feature simultaneously; can improve the control accuracy of pressure controller; change traditional product and can only be applicable to the present situation of protecting and can not being used to control; the demand that makes pressure controller also can be used to control; enlarged the using scope of product; regulating device has been taked the measure of adjustment screw lock, and is constant to guarantee the pressure controller setting value.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the longitudinal section of the utility model pressure controller new structure.
Fig. 2 is the A-A sectional view of Fig. 1 structure.
With reference to Fig. 1,2 pressure controller new structures include: housing 1, terminal 2, contact-carrying reed 3, push rod 4, disc-shaped diaphragm 5, pipe joint 6, connecting base 7, regulating device 8, below the hollow cavity of pipe joint 6 and disc-shaped diaphragm 5, establish a regulating device 8, regulating device 8 comprises adjusts screw 81, taper pin 82 and adjustment spring 83, adjust the below that spring 83 1 ends are held in disc-shaped diaphragm 5, the other end is held in the top of adjusting screw 81, adjusting screw 81 screws in the screw of pipe joint 6, adjust screw 81 and establish a taper hole that runs through 813, establish taper pin 82 in the taper hole 813, taper pin 82 tail ends are established and are torn imperial screw thread open, adjustment screw 81 1 sides are established one and are run through its groove 811 longitudinally, make adjustment screw 81 be the opening tubular structure, adjust the bottom of screw 81 and establish a mounting or dismounting groove 812.
When adjusting the mechanical characteristic setting value of disc-shaped diaphragm 5, screw 81 is adjusted in turn, and the active force of adjusting 83 pairs of disc-shaped diaphragms 5 of spring changes along with the turn of adjusting nail, thereby changes the spinodal decomposition point of disc-shaped diaphragm 5, promptly reaches the purpose of adjusting set point in the adjustment mode.After adjustment is finished, in the taper hole 813 of adjusting screw 81, insert taper pin 82, along with making adjustment screw 81 external diameters that have groove 811, pushing of taper pin 82 expand outwardly, make screw and screw tight engagement, reach tight lock and adjust screw 81, it is loosening that it is not produced in machine run, and the assurance pressure controller is worked reliably.Groove 811 is except that above-mentioned effect, and also as the passage of working medium, pipe joint 6, connecting base 7 and disc-shaped diaphragm 5 all weld, and constitutes the inner space sealing to keep disc-shaped diaphragm 5, pipe joint 6 and connecting base 7.
