Abstract
The utility model relates to a corrosion-resistance parallel double-disc gate valve, which comprises a valve body and a valve rod, wherein a valve core is connected to the valve rod; an air cylinder is arranged on the valve cover; and sealing filler is arranged between the valve body and the valve rod. The gate valve is of a full-bore structure; the gate valve also adopts a top-mounting type design which is convenient to maintain; a valve seal is made of wear-resistance and corrosion-resistance materials; various parts of the valve sealing mechanism are mutually separated; and the valve is of a fully-sealed structure. The corrosion-resistance parallel double-disc gate valve has the advantages of convenience for pipeline cleaning, good tightness, high-temperature resistance, corrosion resistance and long service life.
Description
Technical field
The utility model relates to a kind of gate valve, particularly a kind of corrosion-resistant double disk parallel gate valve.
Background technique
What the tradition gate valve adopted is streamline channel, should not clean pipeline, causes jam easily, thereby damages valve; And conventional valves is safeguarded the palpus throttle down, makes troubles to production.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of corrosion-resistant double disk parallel gate valve.
To achieve these goals, the technological scheme taked of the utility model is:
A kind of corrosion-resistant double disk parallel gate valve comprises valve body, valve rod, is connected with spool on the valve rod; Valve body is provided with valve gap; Cylinder is housed on the valve gap; Be provided with stuffing box packing between valve body and the valve rod; Said gate valve adopts the all-pass gauge structure.
Said gate valve also adopts the last dress formula design that maintains easily.
Said valve seal adopts wear-resisting, corrosion-resistant material to process.
Each part of valve seal mechanism is disconnected from each other.
Said valve adopts full-enclosed structure.
The beneficial effect of the utility model: pipe-line purging convenience, good airproof performance, high temperature resistant, corrosion-resistant, long service life.
Description of drawings
Fig. 1 is a novel corrosion resistant double disk parallel gate valve schematic representation.
Embodiment
A kind of corrosion-resistant double disk parallel gate valve comprises valve body 1, valve rod 3, is connected with spool 2 on the valve rod 3; Valve body 1 is provided with valve gap 4; Cylinder 5 is housed on the valve gap 4; Be provided with stuffing box packing 6 between valve body 1 and the valve rod 3; Said gate valve adopts the all-pass gauge structure.Said gate valve also adopts the last dress formula design that maintains easily; Said valve seal adopts wear-resisting, corrosion-resistant material to process; Each part of valve seal mechanism is disconnected from each other; Said valve adopts full-enclosed structure.
Mangetic core assembly by wedge-shaped blocks 9, about rise piece 8 and left and right sides seal disc 7 etc. constitute, adopt big gap movable connection structure between each parts, can locate voluntarily, free voluntarily, adjustment voluntarily.
The complete shut-down sealing state rotates handwheel moves down valve rod because the effect of wedge-shaped blocks 9 produces two substantially horizontal power left and right sides seal disc 7 is pressed to sealing seat through Stem Mut, forces seal disc 7 closely to contact with sealing seat, reaches the inlet/outlet two way sealed.
Valve wide open shape will is rotated handwheel makes the moving moving connecting mechanism of shipper pole on the valve rod 3 at first overcome wedge-shaped blocks 9 through Stem Mut and the frictional force that rises between the piece 8 adds the big Spielpassung between each parts again; Can make the piece 8 that rises sagging, seal disc 7 inwardly shrinks and the disengaging sealing surface of seat.Rapid, laborsaving, the no jam phenomenon of valve opening. reach the valve wide open state.
