Abstract

The utility model discloses a safety valve of an air compressor. The safety valve of the air compressor comprises a valve body, wherein an air inlet and exhaust holes are formed in the valve body; a spring supporting base is in threaded connected with the upper end of the valve body; a spring is fixedly connected with the lower end of the spring supporting base; a sealing block is fixedly connected with the lower end of the spring; a retainer for retaining the spring at a vertical position is arranged on the periphery of the spring; the outer part of the lower end of the valve body adopts an external thread structure; a threaded through hole is formed in the valve body below the air inlet; a plug is in fixed threaded connection with the threaded through hole; the plug is made of rubber. The safety valve of the air compressor has the beneficial effects as follows: an ejector rod in the prior art is improved into the retainer of the spring and the retainer does not stretch out of the valve body, so that the retainer is not affected by an external force; the safety valve of the air compressor is simple in structure, easy to implement, and relatively convenient to maintain due to arrangement of the manual exhaust holes.

Description

A kind of safety valve of air compressor
Technical field
The utility model belongs to air compressor accessory technical field, the particularly safety valve on air compressor.
Background technique
Air compressor is a kind of general machinery, in more equipment as supporting application.
Existing safety valve of air compressor is that push rod and spring are installed between valve body suction port and air outlet, spring heads on seal ring and makes suction port sealing, the pressure size of safety valve is determined by spring force, and spring force is regulated by adjusting screw, the shortcoming that its prior art safety valve of air compressor exists is that the tail end of push rod exposes, when unexpected masterpiece is used in push rod tail end, the pressure of spring changes, Unloading Effect while not having design, namely do not reach safe object, therefore can cause air compressor pressure to surpass the accident of design pressure.
Model utility content
In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of push rod tail end of protecting and avoids the novel air compressor safety valve that external force is collided.
The utility model is that the technological scheme that its technical problem of solution is taked is:
A kind of safety valve of air compressor, comprise valve body, in valve body, be provided with suction port and exhaust port, a spring supporting seat has been threaded in valve body upper end, spring supporting seat lower end is connected with spring, spring lower end is connected with sealing block, the outer retainer of a keep-spring in vertical position that be arranged with at spring, the outside, lower end of valve body is external thread structure, on the valve body that is positioned at suction port bottom, be provided with a threaded through hole, on the through hole of screw thread, screw thread is connected with obstruction, and described obstruction is that quality of rubber materials is made.
On valve body outside being positioned at described spring supporting seat, be provided with a Cock screw, spring supporting seat is fixed on valve body by Cock screw.
Described valve body upper end tip male thread is connected with a protective cover, and described protective cover upper end integral type is provided with handle.
In the tapped through hole outside that obstruction is installed, be provided with a magic tape, described magic tape is wrapped in the periphery of valve body.
The beneficial effects of the utility model: the utility model is improved to push rod of the prior art the retainer of spring, retainer can not extend to valve body outside, so can not be subject to the impact of external force, by the upper-lower position of Regulation spring supporting base, carry out the pressure of Regulation spring, spring supporting seat holds out against by screw, on valve body below suction port, be provided with the through hole for manual exhaust, through hole is by plug for seal, and make manual exhaust more convenient at obstruction peripheral hardware magic tape, the utility model is simple in structure, easy to implement, and it is convenient when maintenance to be provided with manual exhaust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the utility model be convenient to understand, below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of safety valve of air compressor as shown in Figure 1, comprise valve body 1, in valve body 1, be provided with suction port 2 and exhaust port 3, it should be noted that, a spring supporting seat 4 has been threaded in valve body 1 upper end, spring supporting seat 4 lower ends are connected with spring 5, spring lower end is connected with sealing block 13, the outer retainer 6 of a keep-spring 5 in vertical position that be arranged with at spring 5, the outside, lower end of valve body 1 is external thread structure, on the valve body 1 that is positioned at suction port 2 bottoms, be provided with a threaded through hole 7, on the through hole 7 of screw thread, screw thread is connected with and stops up 8, described obstruction 8 is made for quality of rubber materials.
On valve body 1 outside being positioned at described spring supporting seat 4, be provided with a Cock screw 9, spring supporting seat 4 is fixed on valve body 1 by Cock screw 9.
Described valve body 1 upper end tip male thread is connected with a protective cover 10, and described protective cover 10 upper end integral types are provided with handle 11.
In tapped through hole 7 outsides that obstruction 8 is installed, be provided with a magic tape 12, described magic tape 12 is wrapped in the periphery of valve body 1.
The utility model is improved to push rod of the prior art the retainer of spring, retainer can not extend to valve body outside, so can not be subject to the impact of external force, by the upper-lower position of Regulation spring supporting base, carry out the pressure of Regulation spring, spring supporting seat holds out against by screw, on valve body below suction port, be provided with the through hole for manual exhaust, through hole is by plug for seal, and make manual exhaust more convenient at obstruction peripheral hardware magic tape, the utility model is simple in structure, easy to implement, and it is convenient when maintenance to be provided with manual exhaust.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
