Abstract
Disclosed is an air cylinder driving type high and low pressure valve. The air cylinder driving type high and low pressure valve comprises a valve body and a valve core; the bottom surface of the valve body is provided with a plurality of air sources or air passage ports communicated with a valve cavity, and the top surface of the valve body is provided with a plurality of through holes, which are communicated with the valve core and correspond to the air sources or the air passage ports; a plurality of air cylinders are mounted on the top surface of the valve body in a sealed mode, the piston rods of the air cylinders are connected with sealing rings to form the valve core, the valve cavity is communicated with operating air passage ports on the end surface of the valve body. The air cylinder driving type high and low pressure valve solves the problem that high and low pressure valves in the prior art can be opened and closed only with pressure differences and are prone to opening and closing errors when in combined use, and has the advantages of being simple in structure, easy to produce and maintain, capable of achieving zero-pressure-difference opening and closing of every valve core, interference-free due to independent control, high in compression strength and large in airflow quantity.
Description
Technical field:
The invention of this reality relates to gas valve field, relates in particular to cylinder driving-type height pressure valve.
Background technique:
Gas valve is as gas in pipeline is turned to, dam, unobstructed and block important control means, extensive use in industrial production, from braking model, can be divided at present electrodynamic type, three kinds of pneumatic type and hydrodynamics, hydrodynamic valve has the cause that working liquid body overflows because of when work, so should not use in the machine relevant to production food package, although there is the how logical height pressure valve of various multidigits in electrodynamic type or pneumatic type valve, but DYN dynamic multidigit multiple-way valve adopts single spool structure substantially, so be difficult to gas channels to implement independent control operation, and the multidigit multiple-way valve of pneumatic type, although possess the ability of independent control, but due to the cause of self structure and member, make its working pressure mostly in 1-2.4MPa left and right, so existing valve, no matter be on controlling or in working pressure, can not meet the requirement that machine function increases day by day in some fields.
For example: in bottle stretch blowing machine, in order to make machine have larger throughput, working pressure need to be increased to 3-4MPa left and right, in addition, in order to realize preheating and cooling procedure in stretching bottle blowing process, so not only need multiple air-path interfaces, also need the gas channels of high pressure, low pressure, hot blast or cold wind, exhaust to carry out single control, although the multidigit multiple-way valve of pneumatic type has the product that adopts the single control of many spools, its working pressure is well below machine requirement, so use reluctantly, its operating life also can only remain between 1-2 month, although and 2/2-way valve in electrodynamic type has the working pressure of 2.4-3MPa, but it can not carry out single control to gas channels, so in reality, can only adopt the mode of multiple combination couplings to be used in combination, as everybody knows, not only pipeline connection is loaded down with trivial details to adopt solenoid valve to carry out multiple combination couplings, this or not of air inlet while also easily there is work, the failure problems of this or not of exhaust, its reason comes from that in solenoid valve, to control the aperture of source of the gas minimum, easily stopped by the particulate in working gas, causing adjusting gas circuit stops up and can not can not normally open or close by mineralization pressure official post spool.
In addition, while adopting the mode of multiple combination couplings to be used in combination, in gas circuit, usually need to arrange to be exclusively used in a valve of being engaged in deairing step, in the time of this valve exhaust, because the air pressure of the air pressure in the confined space of workpiece and source of the gas is still in the state of a balance, be not closed so control the valve of source of the gas when exhaust, cause gas in workpiece to be drained from outlet valve with together with gas in source of the gas; As can be seen here, adopt multiple DYN dynamic 2/2-way valves also to have the deficiency of waste source of the gas and the very large noise of generation in conjunction with the mode of coupling.
Model utility content:
In order to solve above-mentioned deficiency, the invention reside in a kind of cylinder driving-type height pressure valve is provided, compared with prior art,, there is the feature that connects and composes spool with the piston rod of cylinder and seal ring in described cylinder driving-type height pressure valve, possesses simple in structure, produce, safeguard easily, each spool zero pressure difference opens and closes, and independently controls and do not interfere with each other, and compressive strength and the large advantage of throughput.Its technological scheme is as follows:
Cylinder driving-type height pressure valve, comprises valve body and spool, is provided with multiple sources of the gas or air-path interface communicates with valve pocket on the downside of described valve body, and it is corresponding that upper side is provided with multiple through holes that communicate with spool and described source of the gas or air-path interface; Some cylinders are installed in the upper side sealing of valve body, and piston rod and the seal ring of cylinder connect and compose spool, and valve pocket communicates with the operation air-path interface being arranged on valve body end face.
The inner port of described source of the gas or air-path interface is provided with the sealing position corresponding with seal ring; In the time of the cylinder operation corresponding with each air pipe interface, the seal ring being arranged on piston rod front end will enter or exit in the space of described sealing position, reaches the independent object that opens and closes gas source interface.
On described valve body, be provided with mounting hole, valve body be fixed on to object when using; The connection mouth of valve body and cylinder is placed with seal ring.
The piston rod of described cylinder is connected with seal ring in valve pocket through through hole.
The beneficial effects of the utility model are: cylinder driving-type height pressure valve of the present invention, to be fixed on the piston rod of the cylinder on valve body and seal ring and connect and compose the cause of spool owing to having adopted, so possess simple in structure, produce, safeguard easily, each spool zero pressure difference opens and closes, and independent control do not interfere with each other, and compressive strength and the large advantage of throughput; Solve prior art height pressure valve and opened and closed because need have pressure reduction, in the time of combination coupling, this has easily occurred and open or not the problem that this closes.
