Abstract
The utility model relates to a clamp-type check valve for an air compressor, which is a check valve installed on a compressed gas pipeline to prevent a gas medium from flowing backwards. The clamp-type check valve comprises a flange and a valve core, wherein one end of the flange is a gas-inlet port, the other end of the flange is a gas-outlet port, the gas-inlet port and the gas-outlet port are on the same axial line and mutually vertical to the installation direction of the valve core, the valve core comprises the mesh valve of a compressor exhaust valve and is connected in a process pipeline in a clamped way through a flange and a bolt on the process pipeline on both ends, and the contact surface of the flange and the valve core is sealed up by a sealing gasket. When going wrong, the valve core can be conveniently taken out for maintenance, thereby the utilization rate of the complete appliance is improved. The utility model not only has simple structure, small volume, light weight and convenient assembly and maintenance and saves a large quantity of metal materials, but also can be opened and closed in time, has low energy consumption, little resistance and low noise and is suitable for popularization.
Description
Technical field
The utility model relates to a kind of wafer type 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 bulky, weight is big, and it is many to consume metallic material, and assembling, maintenance are 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, volume is little, and is in light weight, manufacturing, installation, maintenance convenience, and energy consumption is low, and resistance is little, and noise is low, the safety check that utilization ratio is long.
The technical solution of the utility model is: a kind of wafer type air compressor safety check, constitute by flange plate and spool, it is characterized in that: flange plate one end is a suction port, one end is the air outlet, and on same axis, orthogonal with the installation direction of spool, described spool is made of the netted valve of compressor, directly by flange plate on the process pipe of two ends and bolt folder is connected in the process pipe, the surface of contact of flange plate and spool adopts the gasket seal sealing, unloads bolt and can take out the spool maintenance.
Rivet after the terminal assembling of the valve bolt of spool.
The beneficial effects of the utility model are owing to adopt the netted valve arrangement of compressor exhaust valve, make that noise is little, energy consumption is low, not fragile, spool directly is connected in the pipeline folder by flange plate on its two ends process pipe and bolt in addition, simplified the structure of safety check greatly, and manufacturing is more prone to, overhaul and assemble convenient.

Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the utility model is a kind of wafer type air compressor safety check, form by flange plate (1), flange plate (7) and spool (2), spool (2) directly is connected in the process pipe folder by the flange plate on the process pipe of two ends (1), flange plate (7) and connecting bolt (3), (4), and flange plate (1) and flange plate (7) are sealed by gasket seal (5) and gasket seal (6) respectively with the surface of contact of spool (2).
Referring to accompanying drawing 2 described spools (2) is the netted valve of compressor valve, it comprises valve gap (8), spring (9), buffer substrate tablet (10), 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 gas channel area in the valve body is big, the mass of the valve plate is little, and lift is little, so energy Consumption reduces, resistance force diminishes, reducing noise.
3. because designs simplification, processing and fabricating is more prone to, and assembling, maintenance are convenient, The spare part highly versatile, energy-saving consumption-reducing is suitable for promoting.
Claims (2)
1, a kind of wafer type air compressor safety check, constitute by flange plate and spool, it is characterized in that: flange plate one end is a suction port, one end is the air outlet, and on same axis, vertical mutually with the installation direction of spool, described spool is made of the netted valve of compressor exhaust valve, directly by flange plate on the process pipe of two ends and bolt folder is connected in the process pipe, the surface of contact of flange plate and spool adopts the gasket seal sealing.
2, a kind of wafer type air compressor safety check according to claim 1 is characterized in that: rivet after the terminal assembling of the valve bolt of spool.
