Description

A kind of two filling seal valve

Technical field

The utility model relates to a kind of valve, specifically a kind of two filling seal valve.

Background technique

Engineering pipeline transportation art valve use widely, the basic structure of present valve is co-axial seal setting-in valve seat in valve body, radial installation valve rod on valve body, valve rod in valve body is fixedly mounted with valve plate, valve plate coordinates with valve base sealing, valve plate rotation or movement thus the runner opened and closed in valve seat under the driving of valve rod; The flange plate be connected with pipeline is shaped with outside valve body.

In actual use, the keying of valve and the degree of unlatching all need to regulate according to actual demand very much, the open/close states of valve is observed for the ease of operator, the mode of current employing is the stem outer circumference installation dial outside valve body, valve rod is installed the mark arrow being used to indicate angle, cause the accessory of valve more, install loaded down with trivial details, and indicate that arrow and dial easily damage, working life is shorter.

Model utility content

The purpose of this utility model is to provide a kind of two filling seal valve, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technological scheme:

A kind of two filling seal valve, comprises valve body, adds long-neck, valve rod and Joystick, and be provided with sluice gate in the middle part of described body cavity, sluice gate place is provided with flashboard; Described valve body upper end is connected with and adds long-neck, and add in long-neck and be coaxially provided with valve rod, valve rod is connected with flashboard; The joint adding long-neck and valve body upper end is provided with pad, add below long-neck inner chamber and be provided with lower floor's filler, spacer ring is provided with above lower floor's filler, upper strata filler is provided with above spacer ring, be provided with packing press ring above the filler of upper strata, in the middle part of packing press ring, be surrounded with O type circle, and O type circle is embedded in packing press ring, be provided with valve gap above O type circle, valve gap is connected with valve body is airtight; The described long-neck side that adds is provided with through hole, is provided with leak detection plug screw in through hole, and leak detection plug screw has sealant tape; Be provided with a Joystick stretching out the valve rod upper end outside valve body, valve rod upper-end surface is made as the long rectangle of fillet and flushes with Joystick upper-end surface; A lock collar is fixed with between described Joystick and valve body, this interval, outer, lock collar side is shaped with two catch, uniformly on the outer of the lock collar between two catch be interval with multiple draw-in groove, Joystick lower end is hinged with a spring sheet, and the position of the corresponding draw-in groove in spring sheet lower end is shaped with a projection.

Further, described stem surface chromium plating.

Further, described pad and packing press ring are plastic-steel material.

Compared with prior art, stem surface chromium plating of the present utility model, improves the working life of valve rod, and pad and packing press ring are plastic-steel material, corrosion-resistant; Handle is rotation within the scope of draw-in groove, in order to the opening state of accurate control valve, several gears of the corresponding valve in multiple draw-in groove positions of lock collar, Joystick lower end is hinged with a spring sheet, the position of the corresponding draw-in groove in spring sheet lower end is shaped with a projection, projection is installed on the angle that can lock Joystick in draw-in groove, needs first to compress spring sheet thus makes projection depart from draw-in groove, then rotate Joystick thus the opening degree of regulating valve during adjustment; The utility model uses two groups of fillers, and sealability is very reliable, guarantees the seal pressure of filler to valve rod, increases the pressure ring with O type circle groove, improve sealability further, can reduce the danger of medium loss to greatest extent; Valve rod of the present utility model coordinates with lock collar, and structure is simple, easily controls, and help operator to be more prone to grasp traffic conditions, and structure is simple, the installation of valve part is simple, long service life.

Accompanying drawing explanation

Fig. 1 is the structural representation of two filling seal valve.

Fig. 2 is the structural representation of lock collar in two filling seal valve.

Embodiment

Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.

Refer to Fig. 1-2, a kind of two filling seal valve, comprise valve body 1, add long-neck 2, valve rod 3 and Joystick 5, be provided with sluice gate 11 in the middle part of described valve body 1 inner chamber, sluice gate 11 place is provided with flashboard 12, described valve body 1 upper end is connected with and adds long-neck 2, and add in long-neck 2 and be coaxially provided with valve rod 3, valve rod 3 is connected with flashboard 12, and flashboard 12 is elevated thus the keying of control valve body 1 under the twisting force of valve rod 3, and valve rod 3 chrome-faced, improves the working life of valve rod 3, add long-neck 2 and be provided with pad 21 with the joint of valve body 1 upper end, add below long-neck 2 inner chamber and be provided with lower floor's filler 22, be provided with spacer ring 23 above lower floor's filler 22, above spacer ring 23, be provided with upper strata filler 24, above upper strata filler 24, be provided with packing press ring 25, O type circle 26 is surrounded with in the middle part of packing press ring 25, and O type circle 26 is embedded in packing press ring 25, pad 21 and packing press ring 25 are plastic-steel material, corrosion-resistant, be provided with valve gap 27 above O type circle 26, valve gap 27 is connected with valve body 1 is airtight, described long-neck 2 side that adds is provided with through hole, is provided with leak detection plug screw 4 in through hole, and leak detection plug screw 4 has sealant tape, be provided with a Joystick 5 in valve rod 3 upper end of stretching out outside valve body 1, valve rod 3 upper-end surface is made as the long rectangle of fillet and flushes with Joystick 5 upper-end surface, and valve rod 3 itself replaces the opening state of mark arrow instruction flashboard 12, a lock collar 6 is fixed with between described Joystick 5 and valve body 1, this interval, outer, lock collar 6 side is shaped with two catch 61, uniformly on the outer of the lock collar 6 between two catch 61 be interval with multiple draw-in groove 62, handle rotation in draw-in groove 62 scope, in order to the opening state of accurate control valve, several gears of the corresponding valve in multiple draw-in grooves 62 position of lock collar 6, Joystick 5 lower end is hinged with a spring sheet 7, the position of the corresponding draw-in groove 62 in spring sheet 7 lower end is shaped with a projection 71, projection 71 is installed on the angle that can lock Joystick 5 in draw-in groove 62, need during adjustment first to compress spring sheet 7 thus make projection 71 depart from draw-in groove 62, rotate the opening degree of Joystick 5 thus regulating valve again.
