Abstract

The utility model relates to a pressure pipe valve with fast opening and closing, and is one type of the pressure pipe valve system. The publicly known tank vehicle uses a ball valve as an output switch. Though the ball valve has leakage without using for half of year, the ball valve still is used as the fast opening and closing. The utility model has the performance and the advantage of the pressure pipe valve, and has the advantages of reliable sealing, durability, no medium contacting of the valve body member, good passing ability, the functions of the throttling valve, the belt water faucet and the hot water faucet, fast and slow opening and closing, stepless regulation of the opening, convenient locking and no additional device when in locking.

Description

Quick-operating pressure pipe valve

The present invention relates to a kind of Valve for compressing tubular liner, particularly the snap switch Valve for compressing tubular liner.

Oil is irritated or the oil sump fuel feeding, under the situation that not have control automatically, often needs fast quick-closing valve, closes too late when container is filled and overflows to avoid irritating.Usually used ball valve, but ball valve is prone to seepage very much, be gasoline as medium in the past, and seepage is easy to cause fire; Ball valve body often contacts with medium, as carrying mordant medium, then needs with the manufacturing of energy corrosion-resistant precious metal, cost height; As be used for multiple different medium, because there is the problem of easy to leak in ball valve, it is gapped that medium is inserted institute easily, not easy cleaning; Ball valve also is difficult for going up lock management.

The objective of the invention is to solve ball valve: problems such as easy to leak, contact medium, non-easy cleaning and difficult upward lock management.

The present invention is achieved in that

Adopt " Valve for compressing tubular liner " (afterwards obtaining application number 86210756) of my patent applied for, reach the principle of closing valve, and adopt the special sebific duct of Valve for compressing tubular liner to make the valve channel lining with spherical surface body moulding pipe; The movable mouth structure of built-up joint, the output terminal of " Pressure pipe water tap " (afterwards obtaining application number 87203700) input end of applying for a patent on the same day of valve is supporting therewith also to adopt me; Sebific duct is compressed or loosen (close valve or open valve) with the eccentric wheel control sphere depression bar of band handle; Be provided with the hole of locking with the shank rear on the eccentric wheel.

Sebific duct can be whole medium leather from valve body, and valve body opens and closes member and also can be with oil lubrication work except that avoiding dielectric corrosion and pollution medium, reduces resistance, reduces wear and antirust; When closing valve is that the sphere depression bar is pressed into concave shape to the sebific duct section in passage, and sebific duct is flexible, and necessary specific pressure and the necessary small and dense envelope of sealing force are reliable, the fine finishing of the sealing surface that also omits simultaneously, and the spheroid of the ball valve that also omits will be made with stainless steel; Be subjected to compressing of adjacent elements owing to make the flange at the sebific duct two ends of lining, sealing is reliable, and medium can not infiltrate the gap beyond the sebific duct inner chamber, and the sebific duct inner chamber is a straight tube-like, and passing ability is good, so clean easily; Be drilled with lockhole on the eccentric wheel, convenience valve is locked, and need not add any device.On pipeline, add weldering two small pieces otic placodes when having only the pernicious theft of defence, the hole of pinning eccentric wheel shank rear.

The concrete structure of invention is born by following embodiment and accompanying drawing thereof.

Fig. 1 is a section of structure of the present invention;

Fig. 2 is the A-A sectional drawing of Fig. 1 of the present invention.

Describe CONSTRUCTED SPECIFICATION and the working condition that proposes according to the present invention in detail below in conjunction with accompanying drawing.

Valve body (1) is as T tee fitting T shape, crosspassage is made lining (11) with the special sebific duct of " Valve for compressing tubular liner ", input end adopts the built-up joint of " Pressure pipe water tap ", that is: Female connector fittings (12) has flange to stretch in the short tube of valve body tightening nut (10), press the mouth of pipe little then, fasten the flange of (12), make (10) and (12) can only rotate mutually and can not draw back.Input end adopts the movable mouth (13) and the movable mouth tightening nut (14) of " Pressure pipe water tap ".It is characterized in that: the vertical duct of valve body (1) has clip slot, the eccentric wheel (4) of band handle is housed in the groove, respectively there is a friction plate (5) the eccentric wheel both sides, the extroversion of two friction plates respectively has (6) one of pressure springs, spring one end props up the tube wall of valve body vertical duct, and an end is pushed down friction plate, and friction plate is pushed down eccentric wheel again, produce certain frictional resistance when eccentric wheel is rotated, in certain corner, can stop (self-locking action is arranged) everywhere.Sphere depression bar (2) inner chamber is equipped with pressure spring (9) and pulley base (3); (3) clip slot is equipped with pulley (7) and pulley spindle (8) again, (8) the external diameter both sides that length is stretched out sphere depression bar (2) epimere respectively have 2～3 millimeters, the corresponding subtend open channels of valve body vertical duct inner chamber twice, allow pulley spindle (8) inject in the groove, part (2) and part (3) can only be moved and can not rotate by directed up and down string.The pulley axis hole of sphere depression bar (2) is microscler, makes pulley base (3) compress 3～5 millimeters in the inner chamber of sphere depression bar (2), with acquisition elastic pressure to sebific duct when closing valve.

Be drilled with lockhole a and b(Fig. 1 on the eccentric wheel), a hole can be locked the pass and also can be locked out, and when lock leaves, just locks in a hole by the eccentric wheel position (driving valve position) of Fig. 1; Lock closes then the opposite side that a hole is turned over valve body vertical duct clip slot lock again (promptly first valve closing such as Fig. 1 three dotted lines).As preventing pernicious theft, then on the input pipeline that is abutted against head nut (12), add two otic placodes of weldering such as Fig. 1 C, stay clip slot between two otic placodes, following the arriving in the otic placode clip slot of eccentric wheel shank portion's rear behind the valve closing, the b hole aligns the circular hole of otic placode C and can lock.
