Abstract
The utility model relates to a rubber safety valve for a compressor, which comprises a valve body, wherein, the valve body is provided with an inner cavity. External threads are formed at the lower part of the outer wall of the valve body. A positioning nut with internal threads is arranged at the upper end of the valve body, and is in screw connection with an adjusting nut. The lower end of the adjusting nut extends to the inner cavity of the valve body. A relief port is arranged in the side wall of the valve body under the adjusting nut. The inner wall of the valve body at the relief port or under the relief port is provided with a boss. A push rod orderly penetrates through a center hole of the adjusting nut and the inner cavity of the valve body. A sealing gasket is arranged at the top end of the push rod, and positioned on the boss. The upper part of the center hole of the adjusting hole is provided with an inward shoulder. The head of the push rod has an outward bulge loop. A press spring is clamped between the shoulder and the adjusting nut, so the sealing gasket can seal the inner cavity of the valve body. The rubber safety valve has the advantage that the integral structure is simple, and the function of the safety valve is realized by the simple structure; the safe pressure is determined by the press spring, the elasticity of the press spring is adjusted by rotating the adjusting nut, thereby, the adjustment of the safe pressure is realized, and the operation is convenient.
Description
(1) technical field
The utility model relates to a kind of compressor rubber safety valve.
(2) background technique
Release in time when needing to be equipped with the rubber safety valve on the compressor and guaranteeing that source of the gas air pressure is too high.Existing rubber safety valve structure complexity, therefore complicated operation when adjusting safety pressure presses for a kind of simple in structure, adjustment safety pressure rubber safety valve easy and simple to handle.
(3) summary of the invention
The deficiency of complicated operation when having rubber safety valve structure complexity, adjustment safety pressure now in order to overcome, the utility model provide a kind of simple in structure, adjustment safety pressure compressor easy and simple to handle rubber safety valve.
The technical scheme in the invention for solving the technical problem is: a kind of compressor rubber safety valve, comprise valve body, described valve body has inner chamber, the bottom of valve outer wall is provided with outside thread, the upper end of described valve body is the setscrew nut with internal thread, described setscrew nut is threaded with an adjusting nut, and the inner chamber of described valve body is stretched in the lower end of this adjusting nut; Offer air vent on the sidewall of the valve body of described adjusting nut below, the inwall of the valve body of described air vent place or air vent below has boss, one push rod passes the center hole of described adjusting nut and the inner chamber of valve body successively, the top of this push rod is a sealing gasket, and the sealing pad is shelved on the described boss; The top of the center hole of described adjusting nut has the convex shoulder of convex, and the head of described push rod has the bulge loop of evagination, and a stage clip holds between described bulge loop and described convex shoulder so that the inner chamber of sealing gasket sealed valve body.
Further, the top of described rubber safety valve also is covered with dust cap.
The utility model in use, the outside thread by valve body lower portion is installed on use occasion with it, and the inner chamber of valve body is communicated with the air source of the gas.When the gas pressure of work source of the gas arrived to a certain degree greatly, the pressure of gas overcame the elastic force of stage clip push rod is backed down, and sealing gasket no longer seals, gas can be gone out from air vent, slow down the air pressure of source of the gas, the effect lower push rod in the elastic restoring force of stage clip resets afterwards, and sealing gasket seals once more.
The beneficial effects of the utility model are: 1. overall structure is simple, has realized the function of safety valve with succinct structure.2. safety pressure is determined by stage clip, by the rotation adjusting nut, adjusts the elastic force of stage clip, can realize the adjustment of safety pressure, and is easy and simple to handle.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of compressor rubber safety valve, comprise valve body 1, described valve body 1 has inner chamber, the bottom of valve body 1 outer wall is provided with outside thread, the upper end of described valve body 1 is the setscrew nut 2 with internal thread, and described setscrew nut 2 is threaded with an adjusting nut 3, and the inner chamber of described valve body 1 is stretched in the lower end of this adjusting nut 3; Offer air vent 4 on the sidewall of the valve body of described adjusting nut 3 belows, the inwall of the valve body of described air vent 4 places or air vent 4 belows has boss 5, one push rod 6 passes the center hole of described adjusting nut 3 and the inner chamber of valve body 1 successively, the top of this push rod 6 is a sealing gasket 7, and sealing pad 7 is shelved on the described boss 5; The top of the center hole of described adjusting nut has the convex shoulder 8 of convex, and bulge loop 9, one stage clips 10 that the head of described push rod 6 has evagination hold between described bulge loop 9 and described convex shoulder 8 so that the inner chamber of sealing gasket 7 sealed valve bodies 1.
In the present embodiment, the top of described rubber safety valve also is covered with dust cap 11, to prevent contamination by dust.
The utility model in use, the outside thread by valve body 1 bottom is installed on use occasion with it, and the inner chamber of valve body 1 is communicated with the air source of the gas.When the gas pressure of work source of the gas arrives to a certain degree greatly, the pressure of gas overcomes the elastic force of stage clip 10 push rod 6 is backed down, sealing gasket 7 no longer seals, gas can be gone out from air vent 4, slow down the air pressure of source of the gas, effect lower push rod 6 in the elastic restoring force of stage clip 10 resets afterwards, and sealing gasket 7 seals once more.The safety pressure of safety valve by rotation adjusting nut 3, is adjusted the elastic force of stage clip 10 by stage clip 10 decisions, can realize the adjustment of safety pressure, and is easy and simple to handle.
Claims (2)
