Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of fire-retardant valve.
Background technique
Fire-retardant valve is in particular for valve fire-retardant with the pipeline of flammable explosive gas or liquid transporting, require very high when some high temperature have naked light to the flame retardant property of fire-retardant valve, if security incident appears in bad being easy to of the flame retardant effect of product in this case, cause very large property loss and personal injury.
Summary of the invention
A kind of fire-retardant valve of the utility model design, this product is mainly used in the associated conduit inlet/outlet pipe road junctions such as coal gas conveying, is used for ensureing that in particular cases pipeline flammable explosive gas or liquid can not be revealed, prevents the generation of security incident.
Fire-retardant valve, be made up of two symmetric design valve bodies, need valve body can adopt Flange joint or clip connected according to actual working environment, also can be fixing by being welded to connect, valve body adopts stainless steel to make, and is provided with tri-coupling type steel disc in valve body, the little space that valve inner compartition becomes several sizes equivalent by described tri-coupling type steel disc, described tri-coupling type steel disc inside is provided with flame-resistant sheet, and flame-resistant sheet is filled in the equivalent little space of some sizes that tri-coupling type steel disc is divided into; The tri-coupling type steel disc arranged in two valve bodies all has certain gradient, and in two valve bodies, the gradient direction of tri-coupling type steel disc is contrary.
The beneficial effects of the utility model are by arranging flame-resistant sheet in tri-coupling type steel disc in valve body, when product work ambient temperature raises, flame-resistant sheet can melt to be shut the passage in valve body, flammable explosive gas in prevention pipeline or the circulation of liquid, the generation of effective prevention security incident, because the tri-coupling type steel disc gradient direction in the valve body of two symmetric designs is contrary, in such as left side valve body, the integral inclined angle of tri-coupling type steel disc and horizontal line angle are a, then in the valve body of the right, the integral inclined angle of tri-coupling type steel disc and horizontal angle are then 180 ° of+a, this rightabout gradient design is adopted to be the Safety performance ensureing product further, under equal external environment, if the flame-resistant sheet in valve body starts fusing, because gradient direction is contrary, sealing effect in two valve bodies just in time superposes, if just add seal length on equivalent effect with the sealing effect of structure then in two valve bodies of gradient, the product of reverse gradient structural design, sealing effect is except seal length increases, sealing occurs that the risk at dead angle also reduces by half, therefore the product hermeticity of this structural design can be very good, and safety coefficient is high, is worth consumers in general to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of this model utility;
In figure 1, valve body; 2, tri-coupling type steel disc; 3, flame-resistant sheet.
Embodiment
As shown in Figure 1, fire-retardant valve, be made up of two symmetric design valve bodies 1, need valve body 1 can adopt Flange joint or clip connected according to actual working environment, also can be fixing by being welded to connect, valve body 1 adopts stainless steel to make, tri-coupling type steel disc 2 is provided with in valve body 1, the little space that valve body 1 inner space is divided into several sizes equivalent by described tri-coupling type steel disc 2, described tri-coupling type steel disc 2 inside is provided with flame-resistant sheet 3, and flame-resistant sheet 3 is filled in the equivalent little space of some sizes that tri-coupling type steel disc 2 is divided into; The tri-coupling type steel disc 2 arranged in two valve bodies 1 all has certain gradient, and in two valve bodies 1, the gradient direction of tri-coupling type steel disc 2 is contrary.
By arranging flame-resistant sheet 3 in tri-coupling type steel disc 2, when product work ambient temperature raises, flame-resistant sheet 3 can melt to be shut the passage in valve body 1, flammable explosive gas in prevention pipeline or the circulation of liquid, the generation of effective prevention security incident, because the tri-coupling type steel disc 2 gradient direction in the valve body 1 of two symmetric designs is contrary, in such as left side valve body 1, the integral inclined angle of tri-coupling type steel disc 2 and horizontal line angle are a, then in the valve body 1 of the right, the integral inclined angle of tri-coupling type steel disc 2 and horizontal angle are then 180 ° of+a, this rightabout gradient design is adopted to be the Safety performance ensureing product further, under equal external environment, if the flame-resistant sheet in valve body 1 starts fusing, because gradient direction is contrary, sealing effect in two valve bodies 1 just in time superposes, if just add seal length on equivalent effect with the sealing effect of structure then in two valve bodies 1 of gradient, the product of reverse gradient structural design, sealing effect is except seal length increases, sealing occurs that the risk at dead angle also reduces by half, therefore the product hermeticity of this structural design can be very good, and safety coefficient is high, is worth consumers in general to use.
Above-mentionedly just by reference to the accompanying drawings this model utility simply to be illustrated, can not as the foundation limiting this model utility right protection domain, any intra-class correlation product structure design conceived based on these innovation and creation all belongs to the protection domain of this model utility.
Claims (1)
