Abstract
The utility model discloses a suction valve of a pneumatic airless sprayer. The suction valve comprises a feed joint, a reducing elbow and a connection nut. A valve seat ring is arranged in the connection nut, the upper portion of the valve seat ring is provided with a valve ball and a guide sleeve, the upper portion of the guide sleeve is provided with a baffle, the baffle is pressed through a paint vat connected with the connection nut, a reset spring is arranged between the valve ball and the baffle, and sealing rings are arranged between the connection nut and the valve seat ring and between the connection nut and the paint vat respectively. The suction valve of the pneumatic airless sprayer is simple and compact in structure, and the height of the suction valve is successfully reduced by skillful using of the reducing elbow.
Description
Technical field
The utility model relates to a kind of parts of pneumatic airless sprayer, and concrete is a kind of pneumatic airless sprayer inlet valve.
Background technology
The inlet valve that adopts in existing flush coater is at suction valve body two ends screw thread to be set, and an end links to each other with the attaching nut, and the other end links to each other with elbow, and is bigger in the short transverse size, makes that flush coater integral body is higher.In order to reduce the complete machine height of flush coater, the convenience of construction is moved in increase, and the inlet valve that therefore need design a kind of compact conformation satisfies user's requirement.
The utility model content
The utility model proposes a kind of pneumatic airless sprayer inlet valve, utilize reducing bend successfully to reduce the size of inlet valve short transverse dexterously, reduced the complete machine height of flush coater.
The technical solution of the utility model is achieved in that a kind of pneumatic airless sprayer inlet valve, comprises charging joint, reducing bend and attaching nut, and described attaching nut arranges taper pipe thread, directly is connected with reducing bend.
Further, in the described attaching nut seat ring is set, is provided with sealing ring between described attaching nut and the seat ring.
Further, described seat ring top arranges valve ball and fairlead, and described fairlead inner ring is provided with minimum 3 equally distributed convex tendons.
Further, described fairlead top arranges baffle plate, and described baffle plate is three forked types or cross.
Further, described baffle plate compresses by the coating cylinder that is connected with the attaching nut.
Further, between described valve ball and the baffle plate back-moving spring is set,
Further, be provided with the two seals circle between described attaching nut and the coating cylinder.
The beneficial effects of the utility model are: the utility model utilizes reducing bend directly to be connected with the attaching nut dexterously, seat ring is arranged on attaching nut inside, successfully reduced the size of inlet valve short transverse, reduced the complete machine height of flush coater, the flush coater center of gravity is reduced, be convenient to mobile construction.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the fairlead vertical view.
Fig. 3 is the baffle plate vertical view.
Among the figure: 1, charging joint; 2, reducing bend; 3, attaching nut; 4, sealing ring; 5, seat ring; 6, fairlead; 7, valve ball; 8, back-moving spring; 9, baffle plate; 10, sealing ring; 11, coating cylinder; 12 convex tendons.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of pneumatic airless sprayer inlet valve as shown in Figure 1 comprises charging joint 1, reducing bend 2 and attaching nut 3, on the described attaching nut 3 taper pipe thread is set, and directly is connected with reducing bend 2.In the described attaching nut 3 seat ring 5 is set, is provided with sealing ring 4 between described attaching nut 3 and the seat ring 5.Described seat ring 5 tops arrange valve ball 7 and fairlead 6, and described fairlead 6 inner rings are provided with minimum 3 equally distributed convex tendons 12, arrange 3 in the present embodiment.Described fairlead 6 tops arrange baffle plate 9, and described baffle plate 9 is three forked types or cross, and the baffle plate 9 in the present embodiment is three forked types.Described baffle plate 9 compresses by the coating cylinder 11 that is connected with attaching nut 3.Between described valve ball 7 and the baffle plate 9 back-moving spring 8 is set.Be provided with two seals circle 10 between described attaching nut 3 and the coating cylinder 11.
The utility model is arranged on attaching nut 3 inside with seat ring 5, has successfully reduced the size of inlet valve short transverse, has reduced the complete machine height of flush coater, and the flush coater center of gravity is reduced, and is convenient to mobile construction.And compact conformation is simple, mounting or dismounting are convenient.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
