Abstract
The invention discloses a kind of pressure controller, comprise bellows case, base plate, bellows, microswitch, installing plate, spring leaf and counterbalance weight, described bellows is arranged in bellows case, the connection of bellows lower end connects mouth, and upper end is welded to connect push rod, and push rod runs through the base plate being fixed on bellows case upper end, microswitch is fixing on a mounting board, installing plate is fixed on counterbalance weight, and counterbalance weight is fixed on spring leaf, and spring leaf is arranged on base plate about base plate on two pillars.The invention has the beneficial effects as follows: structure is simple, small in volume, applied widely, long service life, reliability are high, eliminates the error vibrated and cause.
Description
Technical field
The present invention relates to a kind of controller, particularly relate to a kind of small pressure controller.
Background technology
In industrial circle; often can use and measure and control the working pressure of certain equipment; at present; industrial extensive employing be utilize bourdon tube as the pressure controller of photoelastic sensitive material; this controller architecture is complicated, volume is large; and bourdon tube press against microswitch when not working, make microswitch bear very large pressure, therefore microswitch is easy to break down because bearing excessive pressure.
Summary of the invention
Technical matters to be solved by this invention is overcome the deficiencies in the prior art and provide a kind of volume little, the pressure controller that stability and reliability is high.
For reaching above object, 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 arranged in bellows case, the connection of bellows lower end connects mouth, upper end is welded to connect push rod, push rod runs through the base plate being fixed on bellows case upper end, microswitch is fixing on a mounting board, installing plate is fixed on counterbalance weight, counterbalance weight is fixed on spring leaf, and spring leaf is arranged on base plate about base plate on two pillars.
As preferably, described bellows adopts elastic alloy to make.
As preferably, be connected on pillar to relative height that described spring leaf is adjustable.
The invention has the beneficial effects as follows: structure is simple, small in volume, applied widely, long service life, reliability are high, can eliminate along the horizontal and vertical vibration of flexure strip.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural drawing of the present invention.
In 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, composition graphs 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 arranged in bellows case 9, and described bellows adopts elastic alloy to make, error can be reduced, improving control accuracy, when being applied in the fields such as chemical industry, resistant material can be adopted to make; The connection of bellows 2 lower end connects mouth 1, upper-end contact connects push rod, push rod runs through the base plate 3 being fixed on bellows case 9 upper end, when bellows experience pressure and promote negtive micropressure switch walk around change time, if pressure continues to increase, bellows will by base plate 3 stop, and bellows 2 and microswitch 4 are all protected, and ensure that the reliability of work; Microswitch 4 is fixed on installing plate 5, and installing plate 5 is fixed on counterbalance weight 7, and counterbalance weight 7 is fixed on spring leaf 6, and counterbalance weight 7 and microswitch 4 are arranged on the both sides of spring leaf, can eliminate the swing of microswitch; Spring leaf 6 is arranged on base plate 3 about base plate on two pillars, spring leaf not only play the guiding role but also have good longitudinal rigidity, ensures the stability of contact work, and due to spring leaf, to prolong longitudinal rigidity very large, during in this direction if any vibration, the work of whole pressure controller is not almost affected; Be connected on pillar to the described adjustable relative height of spring leaf 6, to regulate the reference position of microswitch, when completing general assembly or at line, if when needing the working point adjusting on-off, nut 8 can be unclamped with spanner, it is that bellows moves up and down that rotation connects mouth 1, changes the distance between bellows upper end connection push rod end face and microswitch contact, thus working point and working range are adjusted.
The course of work of the present invention is as follows: when pressure is increased to a certain value, bellows upper ejector pin promotes microswitch contact and realizes once changing, microswitch a pair normally closed contact is disconnected, another closes normally opened contact simultaneously, when the pressure drops, conversion is realized at another less spot pressure, normally closed contact is made to reply closure state, normally opened contact disconnects simultaneously, due to the vibrational power flow of negtive micropressure switch, be these two transfer points not same spot pressure, these two spot pressures control or alert operation point, pressure reduction between these two spot pressures is exactly the pressure limit automatically controlled, can set up according to the requirement of user.
As described above, be only preferred embodiment of the present invention, is not used for limiting practical range of the present invention, and namely all equalizations done according to the present invention change and modify, and are all the claims in the present invention scope and contain, illustrate no longer one by one here.
Claims (2)
1. a pressure controller, it is characterized in that: comprise bellows case, base plate, bellows, microswitch, installing plate, spring leaf and counterbalance weight, described bellows is arranged in bellows case, the connection of bellows lower end connects mouth, upper end is welded to connect push rod, push rod runs through the base plate being fixed on bellows case upper end, microswitch is fixing on a mounting board, installing plate is fixed on counterbalance weight, counterbalance weight is fixed on spring leaf, spring leaf to be arranged on about base plate on two pillars, be connected on pillar to relative height that described spring leaf is adjustable, the described mouth that connects is connected to bottom described bellows case by nut.
