Abstract
The invention relates to the field of solenoid valves in the pneumatic technology, in particular to a dual-pressure valve. The dual-pressure valve is controlled to work by a PLC and comprises a first solenoid valve and a second solenoid valve, wherein the first solenoid valve and the second solenoid valve are both two-position and three-way direct-acting solenoid valves. The second solenoid valve comprises a pressure input port PII, a pressure output port AII and an exhaust channel. The first solenoid valve comprises a pressure input port PI and a pressure output port AI. The pressure output port AI of the first solenoid valve is communicated with the exhaust channel of the second solenoid valve. According to the dual-pressure valve, the structure is simplified, the air course is shortened, the failure rate is greatly lowered, high-speed switching between two kinds of pressure can be carried out in one air course, high-speed pressurization and decompression can be achieved, and therefore the response speed is increased, and the machining quality and the machining efficiency of products are greatly improved; in addition, an energy-saving module is additionally arranged in a junction box, so that the input power is lowered, and the energy-saving effect is good.
Description
Technical field
The present invention relates to pneumatics solenoid valve market, specifically refer to dual-pressure valve.
Background technique
Dual-pressure valve is also equivalent to two one-way valve composite structure forms, and its effect is equivalent to " with door ", and it has two inlet opening P1 and P2, a delivery outlet A.When P1 and P2 has separately input, spool is pushed to opposite side, A no-output; When P1 and P2 has input simultaneously, A just has output, if P1 and P2 input air pressure not etc. time, the low A of air pressure exports, often when " with door " element uses in dual-pressure valve pneumatic circuit.
Two forced air supply circuit systems in the same circuit of dual-pressure valve of the prior art all adopt two two-bit triplet solenoid valves to add a shuttle valve composition, its system complex, element is many, so bring fault also many, if and speed of response is very slow, flow is very little, pressurization pressure release is slow, can the quality of processing of extreme influence product and work efficiency.
Summary of the invention
For the deficiencies in the prior art, the present invention aims to provide dual-pressure valve, and this dual-pressure valve eliminates shuttle valve, not only simplify structure, shortens gas circuit, and improve speed of response, failure rate is low.
