In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode The above-mentioned technical proposal of type is described in detail.

When specifically used, prevented adhesion hose valve according to one kind described in the utility model, including the valve body worked in coordination And spool, valve body by being formed in two parts of mirror symmetry, spool include fixture, sebific duct 11, the screw rod being connect with fixture and Driving device, fixture include the upper fixture 1 worked in coordination and lower fixture 6, and upper fixture 1 and lower fixture 6 can select cylindrical body The cross section structure that structure, i.e. rod-like structure or plate structure, upper fixture 1 and lower fixture 6 are contacted with sebific duct is identical, upper folder The left end of tool 1 is equipped with first through hole 2, and the right end of upper fixture 1 is equipped with the second through-hole 3, and first through hole 2 and the second through-hole 3 are upper and lower Through-hole is equipped with the first pull rod 4 in first through hole 2, and the second pull rod 5 is equipped in the second through-hole 3, and the first pull rod 4 and second is drawn Bar 5 is orthogonal with upper fixture 1, and the first pull rod 4 and the second pull rod 5 are parallel to each other, and upper fixture 1 can be in 4 He of the first pull rod It walks up and down on the parallel construction of second pull rod 5 composition, the lower end of the lower end of the first pull rod 4 and the second pull rod 5 passes through lower fixture 6 It linking together, the upper end of the upper end of the first pull rod 4 and the second pull rod 5 is linked together by adjusting cross bar 7, the first pull rod 4, Second pull rod 5, lower fixture 6 and adjusting cross bar 7 form a rectangular fixed structure, and the center for adjusting cross bar 7 is equipped on one Under through-hole, screw thread is equipped in through-hole, is named as the first screw hole, equipped with the driving screw 8 matched, driving screw 8 in the first screw hole Inside have a cavity, the inner wall of cavity is equipped with internal screw thread, and internal screw thread is contrary with the external screw thread of driving screw 8, upper fixture 1 it is upper End is connected with sub-screw 10, and sub-screw 10 is connect with screw-internal thread fit, and the upper end of driving screw 8 is connected with driving device, driving dress It sets and can be rotation handwheel 9, be also possible to motor, motor is connected with retarder, and rotation handwheel 9 is rotated by manpower manual real It now operates, motor is to drive driving screw 8 to rotate by motor, realizes positive and negative rotation by retarder.Sebific duct 11 is arranged in upper fixture 1 Between lower fixture 6, the axial direction and fixture right angle setting of sebific duct 11, the structure of sebific duct 11 are intermediate hollow cylindrical structure, Both ends are annular flange 12, and the lower end of valve body is equipped with the flange face matched with annular flange 12, just consolidates annular flange 12 Due on flange face, and thus constitute hose valve and sealing when pipeline is attached, 11 internal layer of sebific duct and outer layer are all made of NBR Rubber is equipped with enhancement layer between internal layer and outer layer, enhancement layer uses skeleton cord fabric, and NBR rubber is nitrile rubber, skeleton curtain Sub- cloth bears load, so that sebific duct is integrally able to bear immense pressure, impact load and sharp pounding, uses the elastic rubber of high abrasion Glue sebific duct, further improves that resisting for sebific duct 11 is wear-resisting, tears, erosion.

In production, by sebific duct 11 and upper fixture 1 or lower fixture 6 by when helping out band connection, help out band and upper fixture 1 or The connection type of lower fixture 6 is will to offer notch on the downside of upper fixture 1, and one end of band will be helped open to connect with upper fixture 1 and installed Cheng Hou welds notch completely again, or notch is connect by connector with upper fixture 1, similarly realizes lower fixture and helps Open the connection of band.

It is increased on sebific duct 11 and helps out band, help out band to aim to solve the problem that under extreme low temperature environment or medium agglomeration state, glue After pipe valve sebific duct is closed for a long time, when opening, unsmooth problem is not opened or opened to hose valve sebific duct.This hose valve helps out Band includes that two structures are identical helps out band, is first band 13 and second to be helped out to help out band 14 respectively, first helps out band 13 by glue Pipe upper end is connect with upper fixture 1, and second helps out band 14 to connect sebific duct lower end with lower fixture 6, and the structure of band is helped out to be for centre The tape or block structure of rubber material, the one end for helping out band to connect with sebific duct 11 are equipped with a projection cube structure, i.e. the first convex block 15, the first convex block 15 also uses rubber material, and the inner wall of sebific duct 11 is arranged in the first convex block 1, with 11 inner wall glue connection of sebific duct one It rising, forms integral structure, all first convex blocks 15 are wrapped in the inner wall of sebific duct 11 by one layer of additional rubber layer 16, and very thin one Layer wrapping layer, will not influence the circulation of fluid, and rubber layer 16 includes preventing the erosion of fluid, improve the use longevity for helping out band Life, helps out the other end of band to connect with fixture, the other end of band is helped out to be again provided with a projection cube structure, i.e. the second convex block 17, Second convex block 17 is set to the inner sidewall of fixture, and the fixture outer wall of the second convex block 17 is passed through with bolt, the two is linked together.

When in use, by taking installation rotates handwheel 9 as an example：Rotary motion handwheel 9 counterclockwise, sub-screw 10 moves downward, and pushes away Dynamic upper fixture 1 is pressed down against sebific duct 11, and sebific duct 11 gradually forms closing shape.At the same time, it adjusts cross bar 7 to move upwards, pass through Two pull rods drive the lower upward sebific duct 11 of fixture 6, and the lower fixture 6 of upper fixture 1 compresses the cross-sectional area of sebific duct 11 simultaneously, reaches Throttle purpose, until valve is closed.Conversely, rotating clockwise rotation handwheel 9, sub-screw 10 drives upper fixture 1 to move upwards, and adjusts Section cross bar 7 drives lower fixture 6 to move downward by driving screw 8, and upper fixture 1 and lower fixture 6 unclamp sebific duct 11 simultaneously, plays opening When the purpose of valve, upper fixture 1 and lower fixture 6 move round about, upper fixture 1 drives sebific duct upper end to move upwards, lower folder 6 drive sebific duct lower end of tool moves downward, and then sebific duct 11 is separated, and there is no the asking together of lower wall glue connection on sebific duct Topic.

Due to the rotation with driving screw 8, upper fixture 1 and the axis of the symmetrical rubber hose 11 of lower fixture 6 synchronize move towards Or it is opposite mobile, and make 11 axis of rubber hose during being extruded, from terms of the vertical section of its axis, it is squeezed laminate section Top and bottom sidewall always with it is whole it is arc-shaped seamlessly transitted with downstream side wall, to be effectively reduced fluid to rubber hose Abrasion, extend the service life of rubber hose.This load of wear-resisting hose valve especially suitable for particle slurry and chemical mediator Body.

In conclusion by means of the above-mentioned technical proposal of the utility model, its fixture two sides after being pressurized by using sebific duct The top and bottom sidewall of upstream and downstream part is integrally arc-shaped smooth transition, not only compensates for the generally existing valve body rubber of traditional hose valve Sebific duct is not wear-resisting, the short defect of service life, while connection helps out band between sebific duct and fixture, avoids lower wall glue on sebific duct The problem of connecting together.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
