Abstract
The utility model discloses a double-clip type check valve. The double-clip type check valve comprises a valve body, a valve clack, a gland and a spring. The valve clack is arranged in the valve body, the valve body and the gland are in threaded connection, a sealing surface is arranged between the valve clack and the valve body for matching, a guidepost is arranged on the back side of the valve clack and in movable fit with a center hole of the gland, a round groove is formed in the lower surface of the valve clack, the spring is arranged on the guidepost of the valve clack in a sleeved mode and arranged between the valve clack and the gland, the gland is of a three-arm structure, a cylindrical boss is arranged on the lower surface of the center hole of the gland, and an anticorrosive coating is arranged on the outer surface of the spring. The double-clip type check valve is compact in whole structure, low in opening pressure of the valve, high in sensitivity, free of overturning when the valve clack is opened or closed, and capable of reducing abrasion of the sealing surface, then ensuring safe and reliable sealing and prolonging the service life of the valve.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of Wafer Check Valves.
Background technique
Safety check is a kind of automatic valve that can prevent that ducted medium from flowing backwards, and safety check comparatively commonly used at present has Swing check valve, Lift check valve and Wafer Check Valves.The flap of Wafer Check Valves of the prior art only passes through the borehole jack of afterbody moulding on valve rod, when flap opens and closes, both need lean on stem guiding, need support by valve rod again, owing to be subjected to the compression shock that media flow produces for a long time, perhaps be subjected to the influence of water hammer, cause check valve sealing or sensitivity to descend.
The model utility content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of Wafer Check Valves, and its overall structure is simply compact, opens and closes flexibly rapidly favorable sealing property, and long service life.
In order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: a kind of Wafer Check Valves, comprise valve body, flap, gland and spring, described flap is arranged on body cavity, and described valve body is threaded with gland, and described flap arranges sealing surface with valve body and cooperates, the described flap back side arranges directional post and gland center hole movingly, described flap lower surface is provided with circular groove, and described spring housing is contained in the directional post of flap, places between flap and the gland.
Described gland is three arm configurations, and the lower surface of gland center hole is provided with cylindrical boss.
Described spring outer surface is provided with corrosion-inhibiting coating.
Compared with prior art, the utlity model has following outstanding advantage and effect: owing to be provided with above structure, the valve opening pressure of this Wafer Check Valves is low, highly sensitive, in the opening-closing process of flap, can not overturn, can reduce the wearing and tearing of sealing surface, thereby guarantee that sealingly secure is reliable, increase the service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As Fig. 1, shown in Figure 2, a kind of Wafer Check Valves, comprise valve body 1, flap 2, gland 3 and spring 4, described flap 2 is arranged on valve body 1 inner chamber, described valve body 1 is threaded with gland 3, gland adopts three arm mechanisms, and at the lower surface of gland center hole cylindrical boss is set, can prevent that spring from producing radial-play, guarantee that valve opening and closing is flexible, stable, described flap 2 arranges sealing surface with valve body 1 and cooperates, the center hole that described flap 2 back sides arrange directional post 21 and gland 3 can prevent effectively that flap from overturning movingly in opening-closing process, also can prevent that flap from coming off because of the flap that the compression shock that is subjected to the media flow generation for a long time causes simultaneously, described flap 2 lower surfaces are provided with circular groove 22, strengthen the anti-pressure ability of flap lower surface, described spring 4 is sleeved on the directional post 21 of flap 2, places between flap 2 and the gland 3, play the spring outer surface corrosion-inhibiting coating is set, overcome spring and corroded the performance impact of bringing to safety check.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
