Abstract
The utility model discloses a flat-plate type sluice valve with good sealing performance. The flat-plate type sluice valve with the good sealing performance comprises a valve box. A valve body is connected with the lower end of the valve box in a sealed mode, and a valve rod seat is connected with the upper end of the valve box. A round valve plate is installed in the valve body in the vertical direction in a sliding mode, a slide rail which is not smaller than the diameter of the valve plate is arranged in the valve box, and a telescopic valve rod is installed in the valve rod seat in a rolling mode. A handle is fixedly connected with the upper end of the valve rod, and the valve plate is fixedly connected with the lower end of the valve rod. A spring is sleeved outside the valve rod, and two ends of the spring are respectively contacted with an inner wall of the valve box and the valve plate in an elastic mode. According to the flat-plate type sluice valve with the good sealing performance, the spring exerts pressure on the valve plate, so that the sealing performance of the sluice valve is improved. The flat-plate type sluice valve with the good sealing performance is simple in structure, convenient to manufacture and use, good in sealing performance, stable in structure and high in practicability.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of plate gate valve of good airproof performance.
Background technique
Plate valve is that a kind of closure member is the slide-valve of parallel gate plate.Its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.
Flashboard is to be controlled by effect and the pressure medium of unsteady flashboard or floating valve seat to the impacting force of valve seat.If Double Disc Flat Gate Valves, the spreading mechanism seen of two flashboards can replenish this impacting force.
Valve seat adopts the O-ring seals sealing and applies the floating valve seat structure of pretightening force, makes the sealing of plate valve inlet-outlet bidirectional; And the keying moment of this structure is only 1/2 of common valve, can reach light open and close valve; When standard-sized sheet, passage is smoothly straight line, and flow resistance coefficient is minimum, without the pressure loss, can lead to ball top cleaning pipeline; Employing need not frequent adjusting with the filling-material structure of selfsealings ability, and open and close are very light, and sealing is reliable, and the stuffing box place is provided with auxiliary seal grease injecting structure, and sealability is definitely reliable, really reaches zero leakage; Solved the disadvantage that General valve filler place the most easily leaks outside; Can automatically lay down the inner chamber high pressure when plate valve is closed, guarantee to use safety; Full-closed structure, barrier propterty is good, can adapt to round-the-clock requirement.
The model utility content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of plate gate valve of good airproof performance to be provided.
The utility model is achieved through the following technical solutions:
A kind of plate gate valve of good airproof performance, comprise valve cap, the described valve cap lower end valve body that is tightly connected, upper end connection valve pole socket, in described valve body, above-below direction is slidably fitted with circular valve plate, be provided with the slideway that is not less than the valve plate diameter in described valve cap, be rotatablely equipped with flexible valve rod on described valve rod base, described valve rod upper end is fixedly connected with handle, the lower end is fixedly connected with described valve plate, described valve rod outside cover has spring, the two ends of described spring respectively with valve cap inwall and valve plate Elastic Contact.
Described valve body and described valve plate surface of contact are equipped with diaphragm seal.
The utility model has the advantages that: the utility model is exerted pressure to valve plate by spring, improves the sealability of gate valve, and is simple in structure, make easy to use, good seal performance, structural stability, practicability is high.
