Abstract
The utility model provides a kind of open detachable pipe clip valve, the upper and lower valve body of this pipe clip valve is tower structure, between upper and lower valve body, rubber pipe is installed, the upper and lower of rubber pipe has a punch holder and a die holder respectively, is connected between upper and lower clamping plate by boom lever with pull bar; When straight journey actuator promotion punch holder moves downward, die holder is gone up to motion simultaneously, presss from both sides flat rubber pipe, and rubber pipe cross section is diminished, thus reaches the effect reducing flow or throttle down; When straight journey actuator promotion punch holder moves upward, die holder moves downward simultaneously, and rubber pipe cross section becomes large, thus opens valve or augmented flow; Owing to being be connected by hook between pull bar with die holder, being fixed by pipe clamp between upper and lower valve body, is adopt the mode of being clamped by bolt between coupling and punch holder, so it is very convenient to change rubber pipe.
Description
Technical field
The utility model relates to a kind of valve, particularly relate to a kind of open can fast dismantling pipe clip valve, belong to valve manufacture field.
Background technique
In chemical industry, the various pipe clip valve of a large amount of use.As shown in Figure 1, install a rubber pipe by Bolt Connection two halves valve body together, an axle sleeve be screwed is installed on valve body top to the structure of common pipe clip valve, installs an outer valve rod in axle sleeve.A handwheel is installed on valve rod top, and stem lower portion is hollow-core construction, and cylindrical is processed with trapezoidal outside thread, endoporus is processed with trapezoidal internal thread, and internal and external threads pitch is equal but rotation direction is contrary.A movable die holder is installed in rubber pipe bottom, and die holder is connected on the spool of top by two directional posts, and spool is screwed outside on valve rod by the trapezoidal internal thread in intermediate hole.A movable punch holder is installed on rubber pipe top, and be welded with an inner valve stem in the middle of punch holder, inner valve stem is combined in the endoporus of outer valve rod by the trapezoidal external thread rotary on it.The guide groove of punch holder both sides is installed on the directional post of both sides, and punch holder can move up and down along directional post.When rotating clockwise handwheel, outer valve rod rotates clockwise, and spool is moved up, and inner valve stem moves down simultaneously.Spool drives die holder to move up by directional post again, and inner valve stem also drives punch holder to move down simultaneously, like this will rubber pipe clamp is flat, thus reduces the sectional area of rubber pipe, and when sectional area is reduced to zero, valve is just thoroughly closed.When rotating counterclockwise handwheel, then pipe clip valve is opened.If handle wheel replaces with the electronic line feed mechanism of many revolutions, then pipe clip valve is exactly electric pipe clamp valve.There is following shortcoming in common pipe clip valve: (1) due to valve body be enclosed construction, when rubber pipe wearing and tearing are broken, ducted fluid will enter in valve body, threaded stem is caused to get rusty, when particularly in fluid, solid content is higher, threaded stem pair makes valve rod rotate difficulty after getting rusty and entering impurity also, cause valve switch fault, even cause electric actuator to damage.(2), because rubber pipe is easily damaged parts, when particularly in fluid, solid content is higher, the wearing and tearing of rubber pipe are very quick, need often to change rubber pipe.During common pipe clamp valve replacement rubber pipe, need to open valve body and could rubber pipe be taken out after removing die holder, changing rubber pipe and bother very much.(3) because rubber pipe is enclosed in valve body, cannot Timeliness coverage when rubber pipe is damaged, be easy to cause valve to damage.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of open Rapid-dismounted pipe clamp valve, is assembled by component such as lower valve body 15, upper valve body 4, rubber pipe 3, punch holder 12, die holder 16, pivoted arm 5, pull bar 14, coupling 7, short tube 1, pipe clamp 2 and bearing pin (10,11,13,17), bolt 9, nuts 8; During assembling, first the guide rod 6 on upper valve body 4 is penetrated in the hole in the middle of upper valve body 4 from bottom to top, then coupling 7 is installed to the top of guide rod 6, and tight a bolt and nut, coupling 7 is fixed on guide rod; Pivoted arm 5 is installed on upper valve body 15 by bearing pin, and with bearing pin, pivoted arm 5 is connected together with punch holder 16; Circular hole 60 end of pull bar 14 is connected together pull bar 14 through the rear bearing pin of elongated slot 50 on punch holder 12 with pivoted arm 5;
Bearing pin 17 is loaded in two circular holes 55 on die holder 16, and pin with cotter pin, then die holder 16 is put into two channel-section steels 25 of lower valve body 15, again rubber pipe 3 is put into half flange 18 at lower valve body 15 two ends, the annular groove 32 on rubber pipe 3 and the bulge loop 29 on half flange 18 are matched; Again the upper valve body 4 assembled is anchored to lower valve body 15 top, the bulge loop 29 on half flange 18 is matched with the annular groove 32 on rubber pipe 3; The large flange 37 of short tube 1 on the end face to rubber pipe 3, the annular groove 39 on large flange 37 is matched with the bulge loop 33 on rubber pipe 3; Pipe clamp 2 is clipped on the flange of half flange 18 and large flange 37, fastening nut and bolt, upper valve body 4, lower valve body 15, rubber pipe 3 and short tube 1 are connected into an entirety; A use the same method the other end short tube 1 and pipe clamp 2 assembles;
Two pull bars 14 are put into the elongated slot 50 at die holder 16 two ends, and the hook 62 of pull bar 14 lower end is hooked on bearing pin, make bearing pin 17 just in time fall in pull bar 14 bottom elongated slot 61, so far, pipe clip valve assembling is complete.
Coupling 7 top is a male flange, male flange has four holes, and bottom is a cylindrical body, and cylindrical body both sides are processed as plane 64, and plane 64 holes 65, and cylindrical sides processes an elongated slot 66, and there is a cylindrical hole 63 coupling 7 inside; Coupling is fast disassembly type;
During installation, the top of guide rod 6 is inserted in the cylindrical hole 63 of coupling 7, and tight a bolt and nut, then coupling is just fixed on the guide bar.
During use, with rapid pipe joint, pipe clip valve is connected on pipeline, shaft coupling 7 by Bolt Connection on the coupling 7 of straight stroke electric or pneumatic actuator bottom; When actuator moves downward, promote punch holder 16 and move downward; Due to the leverage of pivoted arm 5, pull bar 14 moves upward, and drives die holder 16 also to move upward, and such rubber pipe 3 is just flat by folder, and in pipe, cross section diminishes, thus reduces the flow of fluids within pipes; Actuator continues to move downward, until rubber pipe 3 by folder flat be zero to the interior cross section of pipe time, pipe clip valve is thoroughly closed; When actuator moves upward, in the pipe of rubber pipe 3, cross section becomes large, and pipe clip valve is opened, and so just reaches the effect of adjust flux and throttle down.
After using a period of time, if when rubber breakage needs to change, pipe clamp 2 of only need dismantling, unclamps the nut 8 on coupling 7, and the hook of pull bar bottom is taken off from the bearing pin 17 die holder, then upwards mentioning upper valve body 4 can change the taking-up of the rubber pipe 3 of breakage; After changing rubber pipe 3, upper valve body 4 is fallen, then install pipe clamp 2, the nut tightened on coupling 7 normally can use pipe clip valve.
