Description
Technical field
The utility model relates to channel gate valve technology, specifically is a kind of shaped as frame structure stainless steel soft sealing damper valve.
Background technique
The history of the existing more than one thousand years of the use of gate valve, it manufactures and designs existence two big key problem in technology: seal form and material are selected.On material uses, cast iron, carbon steel and stainless steel etc. are arranged at present; On seal form, divide wedge pressure compact form and guide rail compression type two big classes, be divided into metal hard-sealing again and rubber seals two big classes by sealing material.Because of stainless material is light, good corrosion resistance, intensity height, processing dimension is flexible, does not need advantages such as die sinking casting, and along with the downward modulation of material price, with stainless steel is that the gate valve of main material begins by widespread usage, and replacing with materials such as cast iron, carbon steels gradually is the gate valve of main material.
On seal form, the metal hard-sealing gate valve is compared with the rubber sealing gate valve, have advantages such as manufacturing procedure is simple, manufacturing is easy to assembly, but it is very high to requirement on machining accuracy, often in actual use, because processing, installation etc. do not reach requirement, exist poorly sealed, shortcoming such as leakage rate is big.Therefore in industrially developed country such as America and Europes, the metal hard-sealing gate valve almost stopped to produce, using before 20 years, but was also generally using in China and Asian countries.Rubber sealing has begun to prevail in the world at present.Utilize the rubber better elastic, the sealability of gate valve is greatly enhanced, and installation requirement descends greatly.But rely on the distortion of rubber to seal, exist in the opening-closing process of gate valve, the rubber wearing and tearing are big, the problem that turnover rate is high.Because rubber layer is to be glued on the valve buckle or to be riveted on the valve buckle, thereby when rubber layer weares and teares, the rubber layer replacing is very difficult or can not change between the tradition flashboard.In recent years, many useful improvement have been done by each manufacturer on the modes such as installation, maintenance replacing of gate valve sealing material, but the still not basic solutions of problem such as the soft sealing material wearing and tearing are big, turnover rate height.
Summary of the invention
In order to overcome existing gate valve above shortcomings, the utility model proposes a kind of shaped as frame structure stainless steel soft sealing damper valve that adopts stainless steel rubber sealing, wedge pressure compact form, to satisfy the demand of channel with gate valve.
This shaped as frame structure stainless steel soft sealing damper valve, comprise valve buckle, flashboard and be arranged at valve buckle and flashboard between Sealing, it is characterized in that: valve buckle 1 is
Shape " or " day " shape; all have "T"-shaped groove on the munnion of valve buckle 1 and the horizontal frame sealing surface; the cross section is " J " shape or I-shaped rubber seal 4 relies on interference effect swelling in the "T"-shaped groove of described munnion; the cross section is " J " shape or I-shaped rubber seal 8 is pressed on by press strip 9 and bolt 10 in the "T"-shaped groove of described horizontal frame, stainless steel flashboard 3 closely is pressed on by the wedge shape self-locking device and realizes sealing on the described rubber seal 4,8.
At the present popular ubiquitous shortcoming of stainless steel gate valve, the utility model has designed the critical components such as valve buckle, arch structure stainless steel flashboard and wedge shape self-locking device of the T-slot of band installation rubber seal, has solved the replacing difficulty of valve buckle Sealing and has connected insecure problem; Can not the self-locking problem under in off position behind the moving or pneumatic actuator of wedge pressure compact form gate valve distribution; Guide rail compression type gate valve is sealing material excessive wear problem in opening-closing process.Arch stainless steel flashboard has solved the flashboard stiff problem, reduces the stainless steel material cost.
Behind moving, the electronic or pneumatic actuator of this product tennis partner, can be widely used in medium and be water, normal temperature, head and locate with interior irrigation channel, culvert road junction etc. at 10 meters, realize the control of flow or liquid level, be one of visual plant of plumbing and sewage treatment.

Embodiment
Fig. 1-8 is the utility model NQ series stainless steel soft seal gate valve schematic representation.Wherein each several part is: fixed base 7, rubber seal 8, pressing plate 9 and the screw 10 of the guide rail 2 on valve buckle 1, valve buckle 1 munnion, flashboard 3, rubber seal 4, wedge shape self-locking plate 5, spring bolt 6, spring bolt 6.
Its valve buckle 1 is
Shape or " day " shape, valve buckle 1 both sides munnion is provided with the guide rail 2 that is used for flashboard 3 guiding, have "T"-shaped groove on the munnion sealing surface of valve buckle 1, the cross section is " J " shape or I-shaped rubber seal 4 relies on interference effect swelling in the "T"-shaped groove of described munnion; Have "T"-shaped groove on the horizontal frame sealing surface of valve buckle 1, the cross section is " J " shape or " worker " font rubber seal 8 is pressed on by press strip 9 and bolt 10 in the "T"-shaped groove of described horizontal frame, and stainless steel flashboard 3 closely is pressed on by the wedge shape self-locking device and realizes sealing on the described rubber seal 4,8.The J-shaped rubber strip can be installed and dismantle by hand.
The sealing of conventional wedge compression type flashboard is that dependence external force compresses the flashboard sealing layer and the valve buckle sealing layer fits tightly and realize sealing.Therefore, when the external force of cutting off the power supply, die disappeared, the flashboard sealing surface became flexible, the gap occurs and form leakage.Conventional guide rails compression type gate valve sealing material in opening-closing process fits tightly with flashboard all the time, thereby makes sealing material be in stress all the time, causes the sealing material excessive wear.
At above problem, this product specialized designs the wedge shape self-locking device shown in Fig. 1,2,7, the wedge shape self-locking device is made up of the some spring bolts 6 on valve buckle 1 munnion and some wedge shape self-locking plates 5 of being fixed on flashboard 3 munnions, when flashboard is in closed condition, described straight pin 6 tightly is stuck in the draw-in groove of wedge shape self-locking plate 5, makes valve buckle 1 and valve plate 3 lockings.
Be welded with 4 fixed base 7 (see figure 1)s in valve buckle 1 vertical position, fixed base 7 has horizontal slotted hole, is used for horizontal adjustment straight pin 6.Spring bolt 6 is fastened on the valve buckle by fixed base 7, nut.Be welded with wedge shape self-locking plate 5 on flashboard 3, the wedge shape of wedge shape self-locking plate 5 play the guiding role.The decrement of rubber layer can be regulated by moving horizontally of straight pin.When the flashboard closed condition, straight pin is fixed in the draw-in groove of wedge shaped plate 5, realizes self-locking.
When flashboard 3 has only in off position, just compress rubber strip.In make progress along guide rail open mode or opening-closing process, J-shaped rubber strip and flashboard 3 keeps certain intervals, thus fundamentally solved gate valve in opening-closing process to the wear problem of Sealing, greatly reduce the maintain and replace rate of sealing material.
In order to reduce the stainless steel material cost, this stainless steel flashboard 3 adopts the arch welded structure shown in Fig. 4,8.Avoided conventional planar structure flashboard to need very thick steel plate could satisfy the deficiency of rigidity.Stainless steel arch welded structure rigidity height, bearing capacity is big, flashboard weight saving, thereby also reduced manufacture cost.
