Abstract
The utility model relates to an one-way delivery valve comprising a valve base characterized in that: the outer surface of the valve base is an inner concave arch surface, a counterbore is arranged at center of the arch surface, a bolt is provided in the counterbore to press a valve film attaching the arch surface, through holes are provided on the valve base, one side of the through holes faces to the valve film, and the other side faces the inner side of the valve base. A pad ring is provided between the bolt and the valve film. The valve film is a rubber film. The cross section of the valve film is thicker at center and thinner from center to edge. The one-way delivery valve produced by this utility model has advantages of simple structure and low production cost.
Description
Technical field
The utility model relates to a kind of outlet valve, particularly a kind of one-way exhaust valve.
Background technique
At present in the using process of pump, air in the pump need be discharged and could be used, but the structure of existing one-way exhaust valve is complicated, influenced the cost of production of whole water pump, and need exhaust in the use of water pump only is a non-recurrent operation, therefore demand urgently a kind of relatively simple for structure, the one-way exhaust valve that cost of production is less.
Summary of the invention
The purpose of this utility model is the problem that solves the existing cost of production rising of complex structure of water pump one-way exhaust valve in the prior art, provides a kind of relatively simple for structure, the one-way exhaust valve that cost of production is less.The utility model designs a kind of one-way exhaust valve, comprise valve seat, it is characterized in that: the cambered surface that is indent in the outside of valve seat, there is a counterbore in central authorities in cambered surface, there is a bolt to compress a valve block of being close on the cambered surface in the counterbore, through hole is arranged on the valve seat, and the one side of through hole is with respect to valve block, and the another side of through hole is with respect to the valve seat inboard.Between bolt and valve block packing ring is arranged.Valve block is a sheet rubber, and it is thick gradually thin toward the edge that the cross section of valve block is central authorities.The utility model has the advantages that the one-way exhaust valve of being produced is simple in structure, cost of production is little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise valve seat 1 among the figure, it is characterized in that: the cambered surface 2 that is indent in the outside of valve seat 1, there is a counterbore 3 in central authorities in cambered surface 2, there is a bolt 4 to compress a valve block 5 of being close on the cambered surface 2, through hole 7 is arranged on the valve seat 1, the one side of through hole 7 is with respect to valve block 5, and the another side of through hole 7 is with respect to valve seat 1 inboard.5 of bolt 4 and valve blocks have packing ring 6.Valve block 5 is a sheet rubber, and it is thick gradually thin toward the edge that the cross section of valve block 5 is central authorities.
In the use, after gas enters valve seat 1 by through hole 7, the valve block 5 that rubber is made is washed open and discharged outside the valve seat 1, and extraneous gas can only be close to valve block 5 on the inner concave arc surface 2 of valve seat 1 more.
