Abstract
The utility model relates to a multiway switching safety valve connected with a transducer. A plurality of valve cores on a valve stem is driven by the moving valve stem to open or close a plurality of metal valve seats to realize the function synchronous opening and closing. The valve stem of the utility model is connected with an upper valve core and a lower valve core as an entity. The upper valve core has an inclined plane structure, and the lower valve core has a floating ball structure. The valve seats and the valve cores are rigidly sealed via metal to metal, and operating pressure is above 42 MPa. The utility model can be matched with a plurality of transducers, and the problem that leakage can be generated under high pressure or high temperature is solved.
Description
The utility model is a kind of and the joining multi-path handover security of industrial instrument transmitter valve.
In fluid delivery system, sometimes need to finish simultaneously the handover operation of many pipelines, and these switch and mainly all to finish down to multiple-way valve with several stop valves or threeway, four-way at present, and this just causes in the system valve quantity very big, and inconvenient operation.Also the someone designed with the once action of a valve and finished the multiple way and multiple switching valve that the handover operation of many pipelines is used simultaneously, but because working pressure that structural design is limit is low, just leaked when high pressure or high temperature.
The purpose of this utility model has designed a kind of rational in infrastructure exactly at above situation, the safe valve for transducer of unique properties, its working pressure is more than 42MPa, can with the supporting use of present various transmitters, it has overcome the single valve manifold valve causes working pressure and temperature to put forward not high shortcoming because of being subjected to structural limitations, remedied the multiple-way valve complicated operation again, the too much defective of valve in the system.
Principle of the present utility model is according to having a plurality of spools on the valve rod, and when mobile valve rod, a plurality of spools can open or close a plurality of metal seat valves simultaneously, realizes the synchronous switch function.Its concrete technological scheme is: in a valve body, be with two spools on the valve rod, upper valve core is a ramp structure, the steel ball structure of lower valve core for floating; Four and all uneven inclined hole in the arbitrary plane of valve body surface are arranged on the valve body.
Because valve seat and valve body can be made a part, make with metallic material, be sealed into annular rigid seal between spool and the valve seat, so overcome possible that taking place of occurring leak when high pressure or high temperature in multi-functional butterfly valve in the past.Do further below in conjunction with accompanying drawing and to specify:
As shown in the figure: 1. the entrance pressure mouth, 2. the entrance pressure mouth, 3. go out pressure mouth, 4. go out pressure mouth, 5. lower valve core, 6. lower valve base, 7. valve body, 8. valve rod, 9. upper valve core, 10. upper valve base.
The utility model has two entrance pressure mouths and two to go out to press mouthful, and totally four connect mouth.Require it to connect mouth, two to meet mouth and three and connect mouth according to production technology by one.When valve rod (8) move down △ S apart from the time, valve rod drives lower valve core (5) and blocks lower valve base (6), at this moment, connects mouth (1) and is cut off, and connects mouth (2) and communicates with connecing mouth (3) and (4), transmitter is in the position of returning to zero.When valve rod move up △ S apart from the time, valve rod drives upper valve core (9) and blocks upper valve base (10), at this moment, connects mouth (1) and connects mouth (4) and communicate, and connects mouth (2) and communicates with connecing mouth (3), transmitter is in the working position.This shows that when handle during along a ladder shell line Rotate 180 °, drive the displacement amount that valve rod (8) produces △ S, this displacement can make safety valve close or open, thereby reaches required purpose.
Four and all uneven inclined hole in the arbitrary plane of valve body surface are arranged on the valve body of this safety valve (7), thereby the functional reliability of safety valve is greatly improved.Valve rod (8) is made of one with upper and lower spool, and upper valve core (9) is the ramp structure of high finishingness.Lower valve core (5) but be the floating type steel ball structure at automatic capturing center.Simultaneously, upper valve base (10) all is a metallic material with lower valve base (6), even can be combined into a part making with valve body.So the spool and the sealing between the valve seat of safety valve are a kind of rigid seals of annular, make it sealing load and can reach more than the 42MPa, make high temperature also very little simultaneously to the influence of sealing.Therefore the safety valve can be used in work under any rugged environment, can replace equilibrium valve, three valve groups, stop valve and single valve manifold valve.After adopting terraced pitch thread transmission, the handle angle of swing is no more than 180 ° just can make this safety valve reach work or zeroing position, therefore easy to operate, fast, and does not exist because of error in operation causes transmitter and bears the problem that unidirectional static pressure damages.
Claims (1)
- A kind of by the entrance pressure mouth, go out safe valve for transducer that pressure mouth, valve body, valve rod, valve seat, spool form, it is characterized in that:In a valve body, be with two spools on the valve rod, upper valve core is a ramp structure, the steel ball structure of lower valve core for floating; Have on the valve body four with all uneven inclined hole in the arbitrary plane of valve body surface, valve seat and valve body can be made a part, make with metallic material, are sealed into annular rigid seal between spool and the valve seat.
