Abstract
The utility model discloses a stop valve, which comprises a valve body and a valve flap.A metallic sealing ring is arranged between the valve body and the valve flap. The valve flap is equipped with an elastic sealing ring.According to the utility model, both a metallic sealing ring and an elastic sealing ring are arranged between the valve body and the valve flap, thereby eliminating the inevitable angle error between the valve body and the valve flap due to the mechanical processing and improving the sealing performance.Meanwhile, the zero-leakage sealing of valves is realized and the service life of valves is prolonged. The frequent replacement of valves is avoided within the maintenance period of valves.
Description
Technical field
The utility model relates to fluid control field, particularly relates to a kind of stop valve.
Background technique
In recent years, under the high occasion of seal request, generally adopted full-metallic sealing configuration as shown in Figure 1 both at home and abroad.Full-metallic sealed stop valve structure as shown in Figure 1: pile-up welding hard alloy on valve body 1, the same alloy of built-up welding on the flap 2 forms metal o-ring 3.Close to zero leakage in order to ensure valve, only on the basis that sealing surface fits like a glove, just can accomplish.Because sealing surface has certain width, in the time of processing, the angle of two parts can not guarantee not have error, so will accomplish to seal fully, almost is impossibility.Under these circumstances, just need the very big power of closing, remove sealed valve, can reduce the working life of valve and bring inconvenience to the user and apply artificially greater than the power under the normal condition.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is the working life of realizing valve zero leakage sealing and prolonging valve.
(2) technological scheme
For solving the problems of the technologies described above, a kind of stop valve is provided, comprise valve body and flap, have metal o-ring between described valve body and the flap, on described flap, have elastic seal ring.
Preferably, the cross section of described elastic seal ring is V-shaped.
Preferably, offer groove on described flap, described elastic seal ring is positioned at described groove.
(3) beneficial effect
Be set to metallic seal by the sealing of valve body between flap and add elastic packing together, solved because machining and the inevitable valve body that produces and the angular error of flap, improved sealing effect, realized the sealing of valve zero leakage, prolonged the working life of valve, in user's repair cycle, can avoid the frequent replacing of valve.
Description of drawings
Fig. 1 is the structural representation of existing stop valve;
Fig. 2 is the structural representation according to the utility model embodiment's stop valve.
Wherein, 1: valve body; 2: flap; 3: metal o-ring; 4: elastic seal ring.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 2, the stop valve that the utility model provides comprises valve body 1 and flap 2, except metal o-ring 3 is set betwixt, opens a groove on flap 2, and elastic seal ring 4 is set in groove.Preferably, the cross section of described elastic seal ring 4 is a V-arrangement.By increasing the design of soft seal, can avoid because the micro-leakage, particularly High Pressure Difference occasion that the angular error of valve body and flap causes; Improve sealing effect, realized the sealing of valve zero leakage, prolonged the working life of valve, in user's repair cycle, can avoid the frequent replacing of valve.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
Claims (3)
1. a stop valve comprises valve body and flap, it is characterized in that, has metal o-ring between described valve body and the flap, has elastic seal ring on described flap.
2. stop valve as claimed in claim 1 is characterized in that the cross section of described elastic seal ring is V-shaped.
3. stop valve as claimed in claim 1 or 2 is characterized in that, offers groove on described flap, and described elastic seal ring is positioned at described groove.
