Abstract
The utility model relates to a check valve used for an air compressor, which is composed of a casing body and a valve core. The casing body adopts a detachable type and is composed of a valve body and a flange cover, the valve core is composed of an air valve and is tightly pushed against along the axial direction of the valve body via a retainer by a puller bolt. If failure occurs on the valve core, the valve core can be conveniently taken out for maintenance, the trouble for replacing the whole machine and the material waste are avoided, the utilization ratio of the whole machine is enhanced, in addition, the utility model has the advantages that not only the structure is simple, the cost is low, the check valve can be started and closed in time, the energy consumption is low, the resistance is small, the noise is low, and the check valve is suitable for wide popularization.
Description
Technical field
The utility model relates to a kind of air compressor safety check.
Background technique
Safety check is mounted in the fluid line, and relies on its deadweight and the pressure of fluid to block the mechanical device of refluence.Safety check commonly used has two kinds of structural types substantially: a kind of is rotary-open type, and another kind is a rise-fall type.The shortcoming of these safety check is
(1) when valve body is installed, be subjected to the restriction of orientation and angle, and sealability is bad.
The gas meeting produces very big noise, befouling environment when (2) using.
(3) resistance is big, and the energy of consumption is many.
(4) structure is complicated, the processing and fabricating difficulty, and maintenance is difficult for, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, and manufacturing, installation, maintenance convenience, energy consumption is low, and resistance is little, and noise is low, the safety check that the life-span is long.
The technical solution of the utility model is: a kind of air compressor safety check, form by housing and spool.It is characterized in that: housing is dismountable, is made of valve body and blind flange, and valve body is provided with inlet end and outlet side, and its top is provided with equally distributed tapped hole, and bolt is fixed on blind flange on the valve body by tapped hole, unloads blind flange and can take out spool.
Spool is made of air valve, and holds out against along the valve axis direction through puller bolt by a stopper.
Rivet after the terminal assembling of the valve bolt of spool.
Puller bolt holds out against stopper by the internal thread that is evenly distributed on the inlet end valve body, thereby fixed air valve.
Between blind flange and the valve body sealing gasket is arranged.
Description of drawings

Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of embodiment's spool.
Being described as follows of each label among the figure:

Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the utility model is made up of housing and spool, and housing is dismountable, is made of blind flange (2) and valve body (1), and there is sealing gasket the centre, with bolt (5) mount.Be provided with a spool that constitutes by compressor valve (3) on the air flow inlet passage in described valve body (1).This spool (3) holds out against along valve body (1) axial direction through puller bolt (6) by a stopper (4).
Referring to accompanying drawing 3 described spools (3) is the netted valve of compressor valve, it comprises valve gap (8), spring (9), buffer substrate tablet (11), valve block (11), locating stud (12), valve bolt (13), opening pin (14), opening slot nut (15), buffer substrate tablet pad (16), valve block pad (17) (18), its structure is identical with existing compressor air-discharging valve arrangement.
When compressor operating, gas pressure overcomes the elastic force of spring (9), and valve block (11) is steadily opened, and when compressor unloading, valve block (11) quick closedown under the effect of spring (9) elastic force guarantees that gas does not flow backwards, and has played the protective action to compressor.
In conjunction with example as can be known, the utlity model has following superiority:
1. use spring force opening and closing valve block, vertical or horizontally all can install.
2. because of air-flow path area in the valve body is big, the valve block quality is little, and lift is little, so energy consumption reduces resistance force diminishes, noise reduction.
3. simple in structure, make easy to maintenancely, be easy to manufacturing, save cost, be easy to promote.
Claims (5)
1, a kind of air compressor safety check is made up of housing and spool, it is characterized in that: housing is dismountable, constitute by valve body and blind flange, valve body is provided with inlet end and outlet side, and its top is provided with equally distributed tapped hole, and bolt is fixed on blind flange on the valve body by tapped hole.
2, a kind of air compressor safety check according to claim 1, it is characterized in that: spool is made of air valve, and holds out against along the valve axis direction through puller bolt by a stopper.
3, a kind of air compressor safety check according to claim 1 and 2 is characterized in that, rivets after the terminal assembling of the valve bolt of spool.
4, a kind of air compressor safety check according to claim 1 and 2, it is characterized in that: the inlet end valve body is provided with equally distributed tapped hole, and bolt passes tapped hole, and holds out against stopper.
5, a kind of air compressor safety check according to claim 1 is characterized in that: between blind flange and the valve body sealing gasket is arranged.
