Abstract
A rubber safety valve comprises a valve body. An inner cavity is arranged inside the valve body, an air inlet is formed at the lower end of the inner cavity of the valve body, external thread is arranged on the lower portion of the outer wall of the valve body, an air discharge opening is arranged on the middle portion of the lateral wall of the valve body, internal thread is arranged on the upper portion of the inner wall of the valve body, the upper portion of the inner cavity of the valve body is in threaded connection with an adjusting nut through the internal thread, a sealing pedestal is arranged at the air discharge opening, the air discharge opening and the inner cavity of the valve body are sealed via the sealing pedestal, an ejector rod is connected with the sealing pedestal after penetrating through a center hole of the adjusting nut, a pressure spring is arranged between the adjusting nut and the sealing pedestal, and a stop ring used for stopping the sealing pedestal rising is arranged on the inner wall of the inner cavity of the valve body above the sealing pedestal. When relieving pressure, if air pressure is over large, the sealing pedestal can be stopped by the stop ring when the sealing pedestal rises over, thereby avoiding over pressure relieving and preventing the sealing pedestal dashing out of the valve body.
Description
(1) technical field
The utility model relates to a kind of rubber safety valve.
(2) scape technology
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, complicated operation when adjusting safety pressure, therefore designed the rubber safety valve that to regulate safety pressure easily, the general structure of this rubber safety valve is: comprise valve body, valve body has inner chamber, the lower end of the inner chamber of valve body forms suction port, and the bottom of valve outer wall is provided with outside thread, is used to connect air compressor.The middle part of body wall offers air vent, and the top of valve interior wall is provided with internal thread, the top of the inner chamber by this valve body of the internal thread adjusting nut that has been threaded; The air vent place is provided with a gasket base, seal by the sealing base between the inner chamber of air vent and valve body, one push rod is connected with gasket base after passing the center hole of described nut, be provided with stage clip between adjusting nut and the gasket base, its working principle is: air pressure backs down gasket base and realizes release when the air compressor internal air pressure is too high, can realize the adjustment of safety pressure by regulating described adjusting nut.Its shortcoming that also exists is: during release, gasket base is too scurried height sometimes, thereby thereby excessively release or gasket base are rushed out valve body.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing rubber safety valve, the utility model provides a kind of spacing rubber safety valve of gasket base that has.
The technical scheme in the invention for solving the technical problem is: a kind of rubber safety valve, comprise valve body, described valve body has inner chamber, the lower end of the inner chamber of described valve body forms suction port, the bottom of valve outer wall is provided with outside thread, the middle part of body wall offers air vent, and the top of described valve interior wall is provided with internal thread, the top of the inner chamber by the described valve body of the described internal thread adjusting nut that has been threaded; Described air vent place is provided with a gasket base, seal by described gasket base between the inner chamber of described air vent and described valve body, one push rod is connected with described gasket base after passing the center hole of described adjusting nut, be provided with stage clip between described adjusting nut and the gasket base, it is characterized in that: the inwall of the body cavity of described gasket base top is provided with the back-up ring that is used to stop described gasket base rising.
Further, described push rod is located in the described stage clip.
Further, described valve body is made up of upper valve body and following valve body, and described upper valve body is threaded with following valve body, and described air vent is positioned on the described upper valve body, and described back-up ring is positioned at described upper valve body.
Using method of the present utility model is identical with existing rubber safety valve.
The beneficial effects of the utility model are: excessive as air pressure when release, and when excessively rising, gasket base can be blocked by described back-up ring, avoid excessive release, also can avoid gasket base to be rushed out outside the valve body.
(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 rubber safety valve comprises valve body, and described valve body has inner chamber, and described valve body is made up of upper valve body 1 and following valve body 2, and described upper valve body 1 is threaded with following valve body 2.The lower end of the described inner chamber of valve body 2 down forms suction port 4, and the bottom of following valve body 2 outer walls is provided with outside thread 4, and the middle part of body wall offers air vent 5, and the air vent 5 described in the present embodiment is positioned on the described upper valve body 1.The top of described upper valve body 1 inwall is provided with internal thread, the top of the inner chamber by the described upper valve body of the described internal thread adjusting nut 6 that has been threaded; Described air vent 5 places are provided with a gasket base 7, seal by described gasket base 7 between the inner chamber of described air vent 5 and described valve body, one push rod 8 is connected with described gasket base 7 after passing the center hole of described adjusting nut 6, be provided with stage clip 9 between described adjusting nut 6 and the gasket base 7, described push rod 8 is located in the described stage clip 9.The inwall of the upper valve body inner chamber of described gasket base 7 tops is provided with the back-up ring 10 that is used to stop described gasket base 7 risings.
When release, excessive as air pressure, gasket base 7 can be blocked by described back-up ring 10 when excessively rising, and avoids excessive release, also can avoid gasket base 7 to be rushed out outside the valve body.
