Abstract
The invention discloses a pressure controller which comprises a diaphragm capsule box, a base plate, a diaphragm capsule, a microswitch, an installation plate, leaf springs and a balancing weight, wherein the diaphragm capsule is installed inside the diaphragm capsule box, the lower end of the diaphragm capsule is communicated with a joint nozzle, the upper end of the diaphragm capsule is connected with an ejector rod in a welded mode, the ejector rod penetrates through the base plate fixed at the upper end of the diaphragm capsule box, the microswitch is fixed on the installation plate, the installation plate is fixed on the balancing weight, the balancing weight is fixed on the leaf springs, the leaf springs are installed a left support column and a right support column, and the left support column and the right support column are arranged on the base plate. The pressure controller has the advantages of being simple in structure, small in size, light in weight, wide in application range, long in service life and high in reliability, and eliminating error caused by vibration.
Description
Technical field
The present invention relates to a kind of controller, relate in particular to a kind of small pressure controller.
Background technology
In industrial circle; often can use the working pressure of measuring and controlling certain equipment; at present; industrial extensive employing be to utilize bourdon tube as the pressure controller of elasticity sensitive material; sort controller complex structure, volume are big; and bourdon tube is being pressed microswitch when not working, and make microswitch bear very big pressure, so microswitch is easy to break down because bearing excessive pressure.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art and provides a kind of volume little, the pressure controller that stability and reliability is high.
For reaching above purpose, the present invention adopts following technical scheme: a kind of pressure controller, comprise bellows case, base plate, bellows, microswitch, installing plate, spring leaf and counterbalance weight, described bellows is installed in the bellows case, the connection of bellows lower end connects mouth, the upper end is welded to connect push rod, push rod runs through the base plate that is fixed on bellows case upper end, microswitch is fixed on the installing plate, installing plate is fixed on the counterbalance weight, counterbalance weight is fixed on the spring leaf, and spring leaf is installed in base plate on two pillars about base plate.
As preferably, described bellows adopts elastic alloy to make.
As preferably, be connected on the pillar to the adjustable relative height of described spring leaf.
The invention has the beneficial effects as follows: little in light weight, applied widely, the long service life of simple in structure, volume, reliability height, can eliminate along the horizontal and vertical vibration of flexure strip.
Description of drawings
In order to be illustrated more clearly in technical scheme of the present invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural drawing of the present invention.
Among the figure: 1. connect mouth, 2. bellows, 3. base plate, 4. negtive micropressure switch, 5. installing plate, 6. spring leaf, 7. counterbalance weight, 8. nut, 9. bellows case.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is explained in detail, in conjunction with Fig. 1, a kind of pressure controller, comprise bellows case 9, base plate 3, bellows 2, microswitch 4, installing plate 5, spring leaf 6 and counterbalance weight 7, described bellows 2 is installed in the bellows case 9, and described bellows adopts elastic alloy to make, can reduce error, improve control accuracy, when being applied in field such as chemical industry, can adopt resistant material to make; The connection of bellows 2 lower ends connects mouth 1, last end in contact connects push rod, push rod runs through the base plate 3 that is fixed on bellows case 9 upper ends, experience pressure and promote negtive micropressure switch when bellows and walk around when changing, if pressure continues to increase, bellows will be by base plate 3 stop, and bellows 2 and microswitch 4 all are protected, and have guaranteed the reliability of work; Microswitch 4 is fixed on the installing plate 5, and installing plate 5 is fixed on the counterbalance weight 7, and counterbalance weight 7 is fixed on the spring leaf 6, and counterbalance weight 7 and microswitch 4 are installed in the both sides of spring leaf, can eliminate the swing of microswitch; Spring leaf 6 is installed in base plate 3 on two pillars about base plate, spring leaf had not only play the guiding role but also good longitudinal rigidity had been arranged, and guaranteed the stability of contact work, because that spring leaf prolongs longitudinal rigidity is very big, in this direction if any when vibration, to the almost not influence of work of whole pressure controller; Be connected on the pillar to described spring leaf 6 adjustable relative heights, to regulate the reference position of microswitch, when finishing general assembly or using in the outfield, when adjusting the working point of on-off if desired, can unclamp nut 8 with spanner, it is that bellows moves up and down that rotation connects mouth 1, has changed the distance between bellows upper end connection push rod end face and the microswitch contact, thereby makes working point and working range obtain adjusting.
The course of work of the present invention is as follows: when pressure increases to a certain value, the bellows upper ejector pin promotes the microswitch contact and realizes once conversion, the a pair of normally closed contact of microswitch is disconnected, another is to the normally opened contact closure simultaneously, when pressure descends, realize conversion at another less spot pressure, make normally closed contact reply closure state, normally opened contact disconnects simultaneously, because the structure setting of negtive micropressure switch is that these two transfer points are not same spot pressures, these two spot pressures are control or warning working point, pressure reduction between these two spot pressures is exactly the pressure limit of controlling automatically, can set up according to user's requirement.
The above person is preferred embodiment of the present invention only, is not to limit practical range of the present invention, and namely all equalizations of doing according to the present invention change and modify, and are all claim scope of the present invention and contain, and give an example no longer one by one here.
Claims (3)
1. pressure controller, it is characterized in that: comprise bellows case, base plate, bellows, microswitch, installing plate, spring leaf and counterbalance weight, described bellows is installed in the bellows case, the connection of bellows lower end connects mouth, and the upper end is welded to connect push rod, and push rod runs through the base plate that is fixed on bellows case upper end, microswitch is fixed on the installing plate, installing plate is fixed on the counterbalance weight, and counterbalance weight is fixed on the spring leaf, and spring leaf is installed in base plate on two pillars about base plate.
