Abstract
The utility model relates to a sealing element for a movable fulcrum lever bucket-typed low-pressure steam drain valve. The sealing element comprises a drain valve base and a valve flap matched with the drain valve base, wherein the valve flap is spherical, an integrated contact loop line is formed between the spherical valve flap and the drain valve base, all closing force is stressed on a narrower sealing loop line, and thus sealing is strengthened. The sealing element has the advantages that: structure is simple, wear can be avoid to some extent, with the increase of the service time, valve opening diameter of the drain valve base can be appreciably increased due to practical wear, the wear is more, the gas tightness is better, with the increase of friction, the spherical valve flap is more and more deeply embedded in the drain valve base, and accordingly, tightness is ensured.
Description
Technical field
The utility model relates to a kind of parts of low-pressure vapor drain valve, is specifically related to a kind of Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve.
Background technique
Chinese patent ZL201020110168.5 discloses a kind of moving fulcrum lever bucket type low-pressure vapor drain valve, and this drain valve can in time be got rid of water of condensation, and the steam leakage loss is little; Rate of back pressure＞90%; Help water of condensation and reclaim, installation and maintenance are convenient, but find that in use its Sealing is that drain valve valve seat and flap sealing are poor slightly; Trace it to its cause; Find that just this valve seat and flap design are unreasonable, flap must accurately be aimed at valve seat and insert ability excellent sealing (can not crookedly insert), or the not firm problem of sealing promptly occurs after the experience wear slightly with valve seat.
The model utility content
In view of above-mentioned deficiency; The purpose of the utility model is to provide a kind of Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve, and the sealing part is simple in structure, on certain degree, is not afraid of wearing and tearing; Even if flap and valve seat misalignment are inserted, do not influence its sealing yet.
In order to achieve the above object; The utility model has adopted following technological scheme: a kind of Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve; Comprise drain valve valve seat and the flap that matches with the drain valve valve seat, said flap is a globe disk, and globe disk and drain valve valve base chamber formed complete contact loop wire the loop wire contact; All power of closing all concentrate on the narrower sealing loop wire, thereby have strengthened sealing.Said drain valve valve seat or flap are that stainless steel is made, or are that the high titanium alloy making of wear-resistant corrosion-resistant intensity forms.
The beneficial effect of the utility model is: the utility model is simple in structure, on certain degree, is not afraid of wearing and tearing, along with the growth of service time; Actual wear increases the valve opening diameter of drain valve valve seat slightly; And its more wearing and tearing, gas tightness is with regard to better, because along with the increase that rubs; Just more and more deep being absorbed in the valve seat of globe disk, thus sealing guaranteed.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The structural representation that combines with valve seat when Fig. 2 is the globe disk deflect.
1. drain valve valve seats among the figure; 2. ball-type flap.
Embodiment
Below we will combine accompanying drawing that the utility model is done further explanation.
As shown in Figure 1; A kind of Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve; Comprise drain valve valve seat 1 and the flap that matches with drain valve valve seat 1, its flap is a globe disk 2, and globe disk 2 and 1 of drain valve valve seat have formed the complete loop wire (loop wire contact) that contacts; All power of closing all concentrate on the narrower sealing loop wire, thereby have strengthened sealing.As shown in Figure 2, when globe disk 2 deflect, combine with drain valve valve seat 1, do not influence its sealing yet.
Claims (3)
1. Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve; Comprise drain valve valve seat (1) and the flap that matches with the drain valve valve seat; It is characterized in that: said flap is globe disk (2), and is loop wire between globe disk (2) and drain valve valve seat (1) and contacts.
2. the Sealing that is used for moving fulcrum lever bucket type low-pressure vapor drain valve according to claim 1 is characterized in that: said drain valve valve seat (1) is a stainless steel drain valve valve seat.
