Abstract
A soft tube squeezing valve features that its movable mechanical part is not in contact with the liquid in pipeline, resulting in no corrosion to it, higher reliability and long service life elongated by several times, even tens times.
Description
The present invention relates to pipeline valve.
Existing gate valve, the runner axostylus axostyle leakiness water on the valve gap, also easily by liquid corrosion, working life is short.
Existing method by dress flexible pipe valve is that flexible pipe is cut off, and by on valve, this method also has the shortcoming by the dress trouble except having flexible pipe and valve joint easily leak with flexible pipe.
Purpose of the present invention is will be with the mechanical activity of flashboard valve part and ducted liquor separation, thereby can be to the maintenance that partly oils of this mechanical activity, improves this mechanical activity working life partly.
This inventive embodiments: cover in the flashboard valve is pressed one deck flexible pipe, and liquid is to flow in this flexible pipe, and when throttle down, the flashboard of valve can push this flexible pipe, can make the liquid in the flexible pipe stop to flow.Flexible pipe two in this valve is sealed in the pipeline at valve two.The method that flexible pipe is sealed in valve two can have several: with jammed method fixing seal valve inner flexible tube two, as can be with the inwall system at a flexible pipe two slope, with an internal diameter less than this flexible pipe, it is jammed at flexible pipe two that external diameter is slightly larger than the hard tube of (0.2 to 3 mm dia) inner diameter, make between flexible pipe and the valve two inner tube wall sealing water-tight, also should make a slope on the external diameter of this hard tube, this slope helps supportting crowded valve flexible pipe two.In order to guarantee the sealing effect between flexible pipe and the valve, can scribble glue on flexible pipe two and this hard tube.General 5 to 50 millimeters of the length of this hard tube, but 15 to 20 millimeters better (for example) with 33 millimeters pipeline valves of diameter.
Also to do simple improvement in this flashboard valve body, as valve planted agent smoother, no coarse surface, should there be corner angle, flashboard (crimping section should not have corner angle yet downwards), this flashboard can be manufactured without non-ferrous metals such as copper, can there be one deck plastic cement etc. on the surface of flashboard, oblate spheroid can be made in the bottom of this flashboard, and this oblate spheroid is squeezing tube effectively, and to the flexible pipe not damaged.
With lead screw valve is connected with pipeline, this connecting means is identical with the method that existing large-diameter valves is connected with pipeline, but this connecting means must be with an anti-packing ring that leaks, and the present invention makes one with the flexible pipe in this packing ring and the valve body, this is shaped on a limit of protruding hose outside diameter with regard to the two that needs flexible pipe, the effect of this packing ring is just played on this limit, two of this flexible pipe is shaped on a limit of protruding external diameter, height can 2 to 40 millimeters, but 10 to 20 millimeters better (with 33 millimeters pipeline valves of internal diameter for example).
Above-mentioned flexible pipe can be manufactured with rubber, plastic material, can manufacture with various high pressure, low-pressure hose, can manufacture with resistant to elevated temperatures various fibers, also can manufacture with various low temperature resistant fibers, because of the difference of the quality and variety of this flexible pipe, so this above-mentioned valve just can be used in the various pipelines of high pressure, low pressure, high temperature, low temperature.
If the flexible pipe in the above-mentioned valve is removed, be enclosed within on any flexible pipe, this valve can be as the flexible pipe valve.
Other embodiment: flexible pipe is fixed on flashboard and flashboard bottom, seals in two discord valve body of flexible pipe, also can improve the using effect of flashboard valve, but this method can not improve the working life of valve.
To description of drawings: Fig. 1 is the one-piece parts symmetry longitudinal sectional view of soft tube squeezing valve, and the label declaration among the contrast figure: valve top runner set screw nut (1), the screw thread on the nut among the figure does not draw.Handle runner (2).Valve gland (3), the screw thread among the figure on this gland does not have picture.Valve axostylus axostyle (4), the screw thread among the figure on this valve axostylus axostyle does not have picture.Valve axostylus axostyle location lid (5), the screw thread that this location covers among the figure does not draw.Valve flashboard (6), this flashboard can be manufactured with various materials, and being connected of it and axostylus axostyle (4) cooperating situation can be multiple structure.Valve body (7), the screw thread among the figure on the main body does not draw.The tubular plug of jammed flexible pipe blocks up (8).Fig. 2 is the longitudinal sectional view of flexible pipe.Fig. 3 is the stifled sectional view of tubular solid plug, and this plug is stifled to have jammed flexible pipe head and valve body to cooperate effect closely.Fig. 4 is the flashboard transverse sectional view, and the screw thread among the figure on the flashboard does not draw, and this flashboard can also be used plastics, rubber manufacturing with non-non-ferrous metal manufacturing.Fig. 5 is the main body symmetry longitudinal sectional view of A type valve, and the screw thread among the figure does not draw, and realizes with lead screw (bolt) being connected of this valve body and pipeline.Fig. 6 is the longitudinal sectional view of flexible pipe, to the label declaration among the figure: hose body (13), flexible pipe protrudes head (14), this protrudes head (14) can high (greatly), 2 to 40 millimeters in general outstanding flexible pipe face, it has the purposes of packing ring, and this flexible pipe Fig. 6 is by in Fig. 5 valve body.Two of flexible pipe and valve body two are equal substantially.
Valve is by dress explanation: with Fig. 4 flashboard by below axostylus axostyle (4), with valve axostylus axostyle location lid (5) by on valve body (7), respectively with gland (3), handle runner (2) by go up at location lid (5) and axostylus axostyle (4) on.Fig. 2 flexible pipe is pressed in the inlet valve body (7) again, squeeze flexible pipe two with two Fig. 3 plugs stifled (10) plug, flexible pipe (10) and valve body are closely cooperated, thereby reach the purpose at seal tube two, when pressing this valve on water pipe, the water of water pipe can be imported the flexible pipe in the valve, when needs close valve, turn runner (2), make flashboard decline squeezing tube, at this moment valve just can be closed.
The advantage of this invention is: because of the ducted liquid contact of partly getting along well of the mobile machine of valve, so no matter pipeline In what liquid is housed, can not corrode the mobile machine part of valve, thereby the life-span and the valve that have improved valve make With reliability, this valve is compared with existing gate valve, with increasing cost, it is several just can to improve life of valve hardly Doubly, tens times.
