Abstract
The utility model discloses a vent valve piece of a reciprocating type piston compressor. The vent valve piece comprises a valve plate, a vent valve piece body, a stop block and screws, wherein the vent valve piece body is arranged over the valve plate, the stop block is arranged over the vent valve piece body, and mounting holes for penetration of the screws are arranged on the stop block, the vent valve piece body and the valve plate correspondingly; the shape of the stop block corresponds to that of the vent valve piece body, one end of the vent valve piece body is provided with a U-shaped clamping groove, a protruding block is arranged at the end corresponding to the U-shaped clamping groove on the stop block, the U-shaped clamping groove is clamped on the protruding block which bends downwards, and the end of the protruding block is clamped in a square hole of the valve plate. The vent valve piece can be assembled through screws for use, is easy to install, and quite reliable during usage; and the shape and the size of the vent valve piece body are not needed to be accord with those of the valve plate due to a split structure, therefore materials for the vent valve piece are reduced effectively, and the production cost is saved.
Description
Technical field
The utility model relates to a kind of exhaust valve plate of reciprocating-piston compressor, belongs to the exhaust valve plate technical field.
Background technique
At present, in general, small-sized piston formula compressor is generally all-in-one-piece structure with exhaust valve plate, and four screw via holes are arranged on the valve block, by four cylinder head screws it is assemblied on the valve plate; Perhaps the mode by riveted joint is assemblied in exhaust valve plate on the valve plate.
For general reciprocating-piston compressor, piston moves back and forth in the inside of cylinder, and exhaust valve plate is thereupon high speed opening, closure also.Be control noise, need the folding degree of limiting valve sheet clack valve, the integrated type valve block is by carrying out the restriction of folding degree at cylinder cap design one boss to clack valve, and the groundwork of whole valve block partly is clack valve, therefore, for the ease of installing, the profile of valve block and size all must be designed to consistent with valve plate, this will cause the materials of Integral exhaustion type valve block too much, cost up.
The model utility content
The purpose of this utility model is: the exhaust valve plate that the reciprocating-piston compressor that a kind of materials are few, cost is low, split designs is provided, solving existing integrated type valve block must be designed to consistent with valve plate, the waste material, the technical problem that cost is high, thus above-mentioned problems of the prior art can effectively be solved.
The purpose of this utility model is to realize by following technical proposals: a kind of exhaust valve plate of reciprocating-piston compressor, comprise valve plate, exhaust valve plate, limiting stopper and screw, described exhaust valve plate is located at the top of valve plate, limiting stopper is located at the top of exhaust valve plate, and equal correspondence is provided with the mounting hole that passes for screw on limiting stopper, exhaust valve plate and valve plate.
As a kind of optimal way, the shape of limiting stopper is corresponding with exhaust valve plate, an end band U-shaped draw-in groove of described exhaust valve plate, a limiting stopper end end corresponding with the U-shaped draw-in groove is provided with projection, the U-shaped draw-in groove is stuck on the projection, and described projection is down crooked, and its end is stuck in the square hole of valve plate.
As further preferred, the other end of described exhaust valve plate is circular arc.
As further preferred, also comprise spring washer, described spring washer is located at the top of limiting stopper.
As a kind of optimal way, described screw is the crisscross screw with Full Thread FT.
Compared with prior art, the beneficial effects of the utility model: the exhaust valve plate of the utility model reciprocating-piston compressor, can use by the screw assembling, install easily, use very reliably, owing to adopt split type structure, it is consistent that the shape and size of exhaust valve plate are not used in valve plate, thereby effectively reduced the materials of exhaust valve plate, saved fabricating cost.
Description of drawings
Fig. 1 is that the utility model is toward the scheme of installation of exhaust valve plate.
Among the figure, 1-valve plate, 2-exhaust valve plate, 3-limiting stopper, 4-spring washer, 5-screw, 6-projection, 7-U shape draw-in groove, 8-square hole, 9-mounting hole.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Disclosed all features in this specification, or the step in disclosed all methods or the process, except the speciality and/or step of mutual repulsion, all can make up by any way, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose, namely, unless special narration, an embodiment in a series of equivalences of each feature or the similar characteristics.
As shown in Figure 1, the exhaust valve plate of the utility model reciprocating-piston compressor comprises valve plate 1, exhaust valve plate 2, limiting stopper 3 and screw 5.Its erection sequence is: described exhaust valve plate 2 is located at the top of valve plate 1, and limiting stopper 3 is located at the top of exhaust valve plate 2, and equal correspondence is provided with the mounting hole 9 that passes for screw 5 on limiting stopper 3, exhaust valve plate 2 and valve plate 1.Specifically in the present embodiment, also comprise spring washer 4, described screw 5 is the crisscross screw with Full Thread FT, described spring washer 4 is located at the top of limiting stopper 3, spring washer 4 is sheathed on the screw 5, play the effect of buffering, by screw 5 with spring washer 4, limiting stopper 3, exhaust valve plate 2 and valve plate 1 from top to bottom successively series winding be fixed into and be integrated, form split type exhaust valve plate structure, in addition, except screw 5, available other component also, realize this function such as screw rod etc., both can as long as satisfy this base part series winding is integrated.
The shape of limiting stopper 3 is corresponding with exhaust valve plate 2, one end band U-shaped draw-in groove 7 of described exhaust valve plate 2, the other end is circular arc, limiting stopper 3 and U-shaped draw-in groove 7 corresponding end ends are provided with projection 6, U-shaped draw-in groove 7 is stuck on the projection 6, described projection 6 is down crooked, its end is stuck in the square hole 8 of valve plate 1, by the clamping of projection 6 with square hole 8, thus limiting stopper 3 is fixing with valve plate 1, because the fixing of U-shaped draw-in groove 7 and projection 6 relation, so that the exhaust valve plate 2 between limiting stopper 3 and valve plate 1 can accurately be located, by this kind mounting type, exhaust valve plate can be designed to be as small as possible, save the valve block materials.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
