Abstract

The utility model relates to a check valve element. The check valve element comprises a valve base and a valve deck arranged at one end of the valve base. A bolt is connected to the center of the valve base and the center of the valve deck in a penetrating mode. A valve plate is arranged between the valve base and the valve deck. The end, connected with the valve deck, of the valve plate is provided with a buffer plate. A spring which abuts against the buffer plate and the valve plate is arranged on the valve deck. The spring is arranged in a groove formed in the end, connected with the valve base, of the valve deck. Compared with diaphragm check valves, lifting check valves and swing check valves, the check valve element can be more timely opened and closed and can be installed in multiple directions, backflow of a pipeline is restrained, and the pipeline is prevented from being blocked by media.

Description

A kind of check valve spool

Technical field

The utility model relates to universal machine reciprocal compressor air valve technical field, relates in particular to a kind of check valve spool.

Background technique

Thereby universal machine reciprocal compressor is to utilize mechanical energy air to be compressed to the standard equipment that obtains certain pressure air and output supply client use, reciprocal compressor generally comprises valve seat, opens and closes element, elastic element and lift limiter with air valve, its performance directly affects working life and the energy loss of air valve, the check valve spool using in traditional compressor pipeline mostly is diaphragm type, rise-fall type and the outstanding formula that opens, because valve body spool fails to open in time and close, the existing backflow phenomenon that causes pipeline to go out, makes the easy blocking channel of ducted medium.

Model utility content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of check valve spool is provided, and compares former diaphragm type, rise-fall type, hangs and open formula safety check, can open more timely and close, and the multi-direction installation of energy, suppressed pipeline backflow.

The utility model is achieved through the following technical solutions: a kind of check valve spool, comprise valve seat and the valve gap that is arranged on valve seat one end, described valve seat and valve gap center cross-under bolt, between valve seat and valve gap, be provided with valve block, described valve block and valve gap connecting end are provided with buffer substrate tablet, described valve gap is provided with the spring that withstands buffer substrate tablet and valve block, and described spring is arranged in the groove of valve gap and valve seat connecting end.

Further, described valve seat one end arranges connection fixture I, and the other end arranges connection fixture II, and described connection fixture I and connection fixture II are fixedly clamped valve seat.

Further, described valve seat is provided with several valve opening I, and valve seat is provided with the valve opening II of docking with valve opening I.

Compared with prior art, the beneficial effects of the utility model are: the utility model is compared former diaphragm type, rise-fall type, hanged and open formula safety check, can open more timely and close, and the multi-direction installation of energy, suppressed pipeline backflow, prevented that pipeline is by filter medium clogging.

Accompanying drawing explanation

Fig. 1 is the sectional drawing of a kind of check valve spool of the utility model.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, the utility model relates to a kind of check valve spool, comprise valve seat 2 and the valve gap 1 that is arranged on valve seat 2 one end, described valve seat 2 and valve gap 1 center cross-under bolt 5, between valve seat 2 and valve gap 1, be provided with valve block 3, described valve block 3 is provided with buffer substrate tablet 4 with valve gap 1 connecting end, described valve gap 1 is provided with the spring 6 that withstands buffer substrate tablet 4 and valve block 3, described spring 6 is arranged in the groove 12 of valve gap 1 and valve seat 2 connecting ends, described valve seat 2 one end arrange connection fixture I 10, the other end arranges connection fixture II 11, described connection fixture I 10 and connection fixture II 11 are fixedly clamped valve seat 2, described valve seat 2 is provided with several valve opening I 7, valve seat 2 is provided with the valve opening II 8 of docking with valve opening I 7.

In sum, valve gap 1 of the present utility model plays the effect that rises limiter, valve block 3 plays seal action with valve seat 2 laminatings, spring 6 opens and closes element, valve block is moved reciprocatingly, bolt 5 supports whole air valve, make elements combination in air valve together, the pressure difference at air valve two ends make valve block 3 promote springs 6 by valve seat 2 ends to valve gap 1 end motion, air-flow is by the passage of valve seat 2, along with pressure difference changes, make again spring 6 promote valve blocks 3 by valve gap 1 end to valve seat 2 end motions, air-flow is by the passage of valve gap 1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
