Description
Technical field
The present invention relates to the pressure regulating switch technical field, relate in particular to a kind of novel pressure tunable switch apparatus.
Background technology
Being usually used in controlling pneumatic and pressure control switch water loop pressure has a variety of, as using the pressure-regulating device in air compressor machine, in order to the gas pressure in the detecting gas receiver, when gas pressure that the gas pressure in the gas receiver pressurizes greater than pumping, pressure-regulating device forces motor to shut down, then pumping stops gas pressurized being sent into gas receiver, makes the gas that refluxes directly not impact the pumping in the running, and cooperates relief valve to reduce the gas pressure in the gas receiver.
Chinese patent 200520130399.1 discloses a kind of " pressure-regulating device of air compressor machine " in addition, it has body, what body had that air reservoir with air compressor machine joins first takes over, and have and second taking over that air reservoir and pumping are joined, switch module is located at pressing in the chamber and having permanent joint and elastomeric joint of body, permanent joint has contact, elastomeric joint has relative elastic conducting strip, shell fragment and trace interfix and shell fragment is arranged in and presses chamber, trace runs through the connection chamber and extends in the pressure release chamber, the opening of trace endcapped pressure release chamber, when the gas pressure of air reservoir is excessive, promoting the shell fragment distortion makes elastic conducting strip separate with formation with contact with the ejection driving lever to open circuit, then pumping shuts down, and the gas pressure that is refluxed with the pumping in avoiding turning round and damaging drives trace to move so that the opening of pressure release chamber is opened simultaneously, then gas is flowed with the reduction internal pressure by opening, and reaches the pressure release effect.Because the setting of its structure cause own vol bigger, thereby its cost is higher.
Also have in the conventional art, the pressure regulating mechanism more complicated of adjustable in pressure switch, operating is not very convenient.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel pressure tunable switch apparatus, to solve the existing existing many weak points of pressure regulating switch.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of novel pressure tunable switch apparatus comprises pedestal and is compound in the vapour cup of pedestal bottom that described pedestal and described vapour cup define a chamber, and the top in described pedestal is provided with a pressure regulation screwed hole, and the bottom is provided with shoulder hole; Described vapour cup is provided with a working media entrance hole; It is characterized in that, between the shoulder hole of described pedestal and described vapour cup internal upper part, be provided with a push rod guide bracket and a seal membrane, described seal membrane is positioned at the bottom of described push rod guide bracket, and described push rod guide bracket and described seal membrane are separated into the downforce chamber and the gas chamber that powers on described chamber; Have a push-rod hole in the middle of described push rod guide bracket, described push-rod hole is laid a stairstepping push rod that extends upwardly into the gas chamber that powers on; In described pressure regulation screwed hole, be rotary with a screw press, be provided with a pressure spring between described screw press and the described stairstepping push rod upper end; Be provided with fixed contact inserted sheet and the moving contact inserted sheet that ecto-entad inserts the described gas chamber that powers in described pedestal bottom one side, described moving, the fixed contact inserted sheet is positioned at the pedestal outside one end and is welded with lead, the end that described fixed contact inserted sheet is positioned at the gas chamber that powers on is provided with fixed contact, an end that is positioned at the gas chamber that powers at described moving contact inserted sheet has the hole that a multidiameter that holds described stairstepping push rod upper end passes, the end that described moving contact inserted sheet is positioned at the gas chamber that powers on is provided with the moving contact corresponding with described fixed contact, is positioned on the end of the gas chamber that powers at described moving contact inserted sheet and is positioned at the nose bar that both sides, hole that the multidiameter that holds described stairstepping push rod upper end passes are fixed with downward extension; Also be with the transition contacts conducting strip that contacts with nose bar conduction on the described moving contact inserted sheet on the multidiameter of described stairstepping push rod upper end; Described transition contacts conducting strip be provided with described fixed contact inserted sheet on fixed contact contact the transition contacts of conduction with moving contact on the described moving contact inserted sheet.
In order to improve the sealing effectiveness of seal membrane, offer a seal groove on the top of described vapour cup, in described seal groove, be placed with sealing ring.
Being placed with the spring guide bracket on described stairstepping push rod, conflicts on described spring guide bracket in the bottom of described pressure spring.
Pedestal of the present invention, push rod guide bracket and stairstepping push rod all adopt non-conducting material to make.
The novel pressure tunable switch apparatus course of work of the present invention is: when pressure chamber does not have pressure instantly, the stairstepping push rod is under the effect of pressure spring pretightning force, in a state of nature, transition contacts on the transition contacts conducting strip only contacts with moving contact on the moving contact inserted sheet, and do not contact with fixed contact on the fixed contact inserted sheet, whole pressure tunable switch apparatus is in normally open, not conducting between moving contact inserted sheet and the fixed contact inserted sheet.After gas or liquid medium enter into the downforce chamber of vapour cup by the working media entrance hole, along with the increased pressure in the downforce chamber, the pressure that increases will act on push rod through seal membrane after surpassing the predefined force value of pressure spring, promote push rod and move upward.The push rod that moves upward drives the transition contacts conducting strip and also moves upward thereupon, and the transition contacts conducting strip that moves upward is subjected to the nose bar effect on the moving contact inserted sheet, its outer rim is bent downwardly, fixed contact conduction on transition contacts and the fixed contact inserted sheet on the transition contacts conducting strip is contacted, moving contact inserted sheet and the conducting of fixed contact inserted sheet, connect circuit, simultaneously the pressure spring accumulation of energy.After closing gas or liquid medium, pressure in the downforce chamber reduces gradually, be lower than the maximum pressure value of pressure spring setting when pressure after, pressure spring discharges, the compressing push rod moves downward, the push rod that moves downward drives the transition contacts conducting strip and resets, and the fixed contact on transition contacts on the transition contacts conducting strip and the fixed contact inserted sheet breaks away from, and whole pressure tunable switch apparatus is got back to normally open again.The present invention also can be designed to normally off, the course of work and described above similar.The present invention can regulate the force value of pressure spring by screw press.The present invention has simple in structure, is active in one's movements the advantage that force value is easy to adjust.
