The dual-safety straight flow shutoff valve with the corrugated pipe has the following technical effects: the structure is novel and unique, the length size of the valve body is small, the weight is light, and the manufacturing cost is low; the structure of the valve body not only can guarantee the requirements of a swing check valve, but also can meet the design requirements of the straight flow shutoff valve, thereby naturally realizing the functions of shutoff, checking and throttling, so that one valve has a plurality of purposes; a medium has a straight flow direction and hardly has flow resistance, thereby saving energy; and the sealing surface belongs to zero friction, has good sealability and long service life, and is a first-choice regeneration product on a chlorine gas conveying tube.
Description
Technical field
The utility model relates to a kind ofly many does not have filler corrugated pipe direct-current stop valve with dual fail-safe, specifically, relates to a kind of adjustable direct current screw down nonreturn valve that is used for preventing on the chemical industry chlorine pipeline medium back flow, has another name called the axial flow screw down nonreturn valve.
Background technique
The passage of traditional stop valve circulation becomes S shape, and the medium transport flow resistance is big, and energy consumption is high, and economic performance is the poorest, besides length is the longest, weight is maximum, cost is the highest.This is stop valve three big in the valve industry.
As everyone knows, filler is the least reliable seal element in the valve industry, also is the most too busy to get away sealing material, although on the chlorine pipeline model utility bellows, but bellows in a single day break, consequence is hardly imaginable.For safety, it is thrifty to have only the mechanism that uses a complicacy that filler is guaranteed as ripple again, and this cries the dual fail-safe of bellows filler.
Safety check is a kind of indispensable safety auto-controlled valve on pipeline, and at present, China's chemical industry is not specialized in the check valve special on the chlorine pipeline, all uses general check valve on the chlorine pipeline; Because sealed attachment form and structure are unreasonable, Sealing and material are not corrosion-resistant, and damage is prone to come off; Be prone to leak, even security incident takes place, valve is short working life; Change frequently, influence is produced, and causes economic loss.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of existing technology, and the chlorine special-purpose multifunctional selfsealings dual fail-safe corrugated pipe direct-current stop valve of a kind of novel structure, good seal performance, safe and reliable, long service life is provided.
The dual fail-safe corrugated pipe direct-current stop valve of the utility model; Comprise valve body (1), be located at the sphere flap (4) of valve body (1) top, be located at the flap support (7) of sphere flap (4) top; Be located at the bulb cap (8) of flap support (7) top; Be located at the inner rack pin shaft (9) of bulb cap (8), be located at the bellows (10) of bulb cap (8) top, be located at bellows (10) inboard valve rod (11) and Stem Mut (13); Be located at the valve gap (12) in bellows (10) outside; Be located at the flange (14) between bellows (10) and the Stem Mut (13), be located at the bonnet cap (15) on the valve gap (12), be located at the hand wheel shaft (16) that Stem Mut (13) top links to each other with Stem Mut (13) through coupled axle-pin; Be located at the graphite wire netting back seal element (17) and the rolling bearing (18) in hand wheel shaft (16) outside; Be located at the handwheel (19) of hand wheel shaft (16) outer upper, be located at the belleville spring (20) and the fastening screw nut (21) of handwheel (19) top, wherein valve body (1) is provided with and flows to sign (3); Sphere flap (4) bottom is provided with ball face sealing face (2), is provided with divided ring (5) and weld seam (6) between sphere flap (4) and the flap support (7).
The dual fail-safe corrugated pipe direct-current stop valve of the utility model has following technique effect:
1) novel structure is unique, and the valve body length dimension is little, and is in light weight, low cost of manufacture.
2) valve body structure can guarantee the requirement of Swing check valve, can satisfy the designing requirement of direct current stop valve again, has become naturally by, non-return, throttling, multi-purpose valve;
3) MEDIA FLOW does not almost have flow resistance to straight-through, and is energy-conservation;
4) sealing surface belongs to zero friction, good seal performance, and long service life is the first-selected product of the replacement on the chlorine delivery line.
Description of drawings
Fig. 1 is the cross-sectional view of the dual fail-safe corrugated pipe direct-current stop valve of the utility model.
Wherein, 1 is valve body, and 2 is the ball face sealing face, and 3 for flowing to sign, and 4 is the sphere flap, and 5 is divided ring; 6 for putting weld seam, and 7 is the flap support, and 8 is the bulb cap, and 9 is rack pin shaft, and 10 is bellows, and 11 is valve rod; 12 is valve gap, and 13 is Stem Mut, and 14 is flange, and 15 is bonnet cap, and 16 is hand wheel shaft; 17 is graphite wire netting back seal element, and 18 is rolling bearing, and 19 is handwheel, and 20 is belleville spring, and 21 is fastening screw nut.
Embodiment
Further specify the utility model through embodiment below.Should correct understanding be: the embodiment of the utility model is only used for the utility model is described and provides, rather than to the restriction of the utility model.So, under the model utility prerequisite, the simple modifications of the utility model is all belonged to the utility model and requires the scope protected.
As shown in Figure 1; The dual fail-safe bellows stop valve of the utility model comprises valve body (1), is located at the sphere flap (4) of valve body (1) top, is located at the flap support (7) of sphere flap (4) top; Be located at the bulb cap (8) of flap support (7) top; Be located at the inner rack pin shaft (9) of bulb cap (8), be located at the bellows (10) of bulb cap (8) top, be located at bellows (10) inboard valve rod (11) and Stem Mut (13); Be located at the valve gap (12) in bellows (10) outside; Be located at the flange (14) between bellows (10) and the Stem Mut (13), be located at the bonnet cap (15) on the valve gap (12), be located at the hand wheel shaft (16) that Stem Mut (13) top links to each other through coupled axle-pin; Be located at the graphite wire netting back seal element (17) and the rolling bearing (18) in hand wheel shaft (16) outside; Be located at hand wheel shaft (16) outside and the handwheel (19) above graphite wire netting back seal element (17) and rolling bearing (18), be located at the belleville spring (20) and the fastening screw nut (21) of handwheel (19) top, wherein valve body (1) is provided with and flows to sign (3); Sphere flap (4) bottom is provided with ball face sealing face (2), is provided with divided ring (5) and weld seam (6) between sphere flap (4) and the flap support (7).
The workflow of the stop valve of the utility model is following:
When valve open; Handwheel (19) rotation counterclockwise drives hand wheel shaft (16) direct transmission Stem Mut (13) rotation under the effect of coupled axle-pin successively, under the effect of screw thread, makes valve rod (11) when straight line rises to top dead center; Valve wide open; When medium flowed to sign (3) direction entrance point and gets into valve body through valve body (1), entrance point pressure was greater than outlet end, and can push the circulation that is in line of sphere flap medium automatically open through the pressure of medium.In case medium has the possible sphere flap (4) of backflow to close automatically, becomes safety check.If medium does not reflux when needing the positive closing valve, make the decline of valve rod (11) straight line force flap support (7) to compress sphere flap (4) rotation of handwheel clockwise direction and again handwheel is locked until positive closing.
