Abstract
The utility model discloses a novel high temperature resistance check valve, having a valve body; the valve body is provided with an air inlet port and an air outlet port, and a cavity is arranged inside the valve body; and the utility model is characterized in that: the circular valve is arranged at the opening of cavity inside the valve body at the air outlet port, the combined sealing working surface is arranged at the circular valve, and the easy dismountable valve cover is arranged on the valve body. The favorable effects of the utility model are: simple structure, ingenious design, good sealing, long performance life of valve plate, convenient replacement of valve elements.
Description
Affiliated technical field:
The utility model relates to the compressed air unit in the mechanical technique, or a kind of valve of special use, specifically, is a kind of novel fire resistant one-way valve of used for air compressor.
Background technique:
Existing one-way valve, as one-way valve and include unloading valve of one-way valve member etc., though structure is simpler, but wherein employed valve block, generally be more flimsy, fall short of working life, mainly is because valve elements such as valve block constantly are worn in long-term frequent impact work, even damage the turnover rate height.And existing one-way valve structures form makes that replacing valve element is relatively more difficult, whole one-way valve need be disassembled from air compressor usually, just can carry out.
The model utility content:
The purpose of this utility model provides a kind of simple in structure, good airproof performance, valve block long service life, changes valve element novel fire resistant one-way valve easily.
Technical solution of the present utility model is: a kind of novel fire resistant one-way valve, valve body is arranged, suction port and air outlet are arranged on the valve body, cavity is arranged in the valve body, it is characterized in that: the valve body inner cavity opening in the air outlet is equipped with ring valve, ring valve has the compound seal working surface, and type valve gap easy to assemble is housed on the valve body.
In the ring valve described in the utility model valve seat is arranged, spring seat is housed on the valve seat, valve seat and or spring seat on have the air-flow through hole, air-flow through hole loam cake has ring-shaped valve.Valve seat and spring seat rely on bolt, nut to link.Air-flow through hole on the valve seat is the waist shaped hole that five equilibrium distributes.The annular seal working surface is arranged on the opposing side of valve seat and spring seat, and valve block is placed on the annular seal working surface, between valve block and spring seat spring is housed.Be stained with resistant to elevated temperatures soft thing on the compound seal working surface of ring valve.The type valve gap easy to assemble that is equipped with on the valve body can be positioned on the same axis with ring valve.The inner of type valve gap easy to assemble is pressed on the ring valve, and the outer end spiral shell is loaded on the valve body.
The beneficial effects of the utility model are: simple in structure, valve elements convenience such as design is ingenious, good airproof performance, valve block long service life, replacing valve block.
Description of drawings:
Fig. 1 is the structural representation of a kind of novel fire resistant one-way valve of the present utility model;
Fig. 2 is the structural representation of the ring valve in the utility model;
Fig. 3 is the local structure for amplifying schematic representation of the air-flow through hole in the ring valve of the present utility model.
Embodiment:
Fig. 1 has described an embodiment of the present utility model, this example is a kind of one-way valve that is used on the air compressor, in this embodiment, valve body 1 is arranged, suction port 2 and air outlet 3 are arranged on the valve body 1, in the valve body 1 cavity is arranged, 3 valve body inner cavity opening is equipped with ring valve in the air outlet, ring valve has the compound seal working surface, is stained with resistant to elevated temperatures soft thing 14 on it.The valve gap 4 of easy to assemble and type easy to maintenance is housed on the valve body of ring valve.
Fig. 2, Fig. 3 have described the ring valve that is adopted in the utility model jointly, and valve seat 6 is wherein arranged, and spring seat 7 is housed on the valve seat 6, valve seat 6 and or spring seat 7 on have air-flow through hole 8, be stamped ring-shaped valve 9 on the air-flow through hole 8.Valve seat 6 relies on bolt 10, nut 11 to link with spring seat 7.Air-flow through hole 8 on the valve seat 6 is the waist shaped hole that five equilibrium distributes on circumference.On the opposing side of valve seat 6 and spring seat 7 annular seal working surface 12 is arranged, valve block 9 is placed on the annular seal working surface 12, and 7 of valve block 9 and spring seats are equipped with spring 13.Sticking or be embedded with resistant to elevated temperatures soft thing 14 on the sealed working face 12 of ring valve.The type valve gap easy to assemble that is equipped with on the valve body can be positioned on the same axis with ring valve, and the inner of type valve gap easy to assemble is pressed on the ring valve, and the outer end spiral shell is loaded on the valve body.
The utility model also can adopt other suitable embodiment, as is used for the device that unloading valve, noise elimination unloading valve etc. comprise one-way valve member.
