Abstract

An improved structure of a relief valve mainly comprises a body that is tubular and is provided with a relief hole, a pressure regulation member mounted to the body and provided with a sealing rubber, and a non-return member. The body is provided with an insertion opening and a gas outlet; a channel is formed between a gas inlet and the gas outlet; the channel is provided with a support part; the pressure regulation member is fit over the gas inlet and; and the non-return member is mounted to the gas outlet. The pressure regulation member is connected with a pumping device and the gas outlet is connected to an object to be inflated. The pressure regulation member may set the pressure value (psi, bar) of the object to be inflated, such that gas pressure enables inflation of the object to be inflated via the channel.

Description

Improved junction of pressure relief valve

The improved structure of the pressure relief valve, especially for connecting the air pump and the inflator to form a charge, and setting the pressure value of the object to be inflated, and when the gas to be inflated reaches the pressure value, the air is released from the pressure release hole of the body An improved structure of the pressure relief valve that allows the inflated body to maintain a stable inflation state.

Generally, when a tire of a vehicle such as a bicycle waits for an inflator to inhale, the air pump is usually connected to the nozzle of the tire by a pipe body, and the air is directly injected into the tire by the air pump. Since the amount of air to be inflicted involves the elasticity of the tire, too much or too little is not suitable, and the pressure value cannot be known from the outside. Therefore, the user usually puts the hand on the nozzle after the air is exhausted by hand or with a pressure gauge. Observing the pressure value is not only troublesome but also inconvenient to operate. Some air pumping devices have pressure gauges for displaying pressure values, but the data of these pressure gauges are only for reference and cannot accurately display the pressure state. In view of this, the applicant has been continuously researching and experimenting to improve the improved structure of a pressure relief valve, so that when the gas to be inflated is saturated, the air is released from the pressure relief hole, so that the gas to be inflated remains stable. The state, in turn, makes the filling operation more convenient.

The main object of the present invention is to provide an improved structure of a pressure relief valve for connecting an inflator such as an air pump and a tire to form an inflation, and the pressure value of the to-be-inflated body can be set by the pressure adjusting member to reach the inflated object. At this pressure value, the air is released from the pressure relief hole of the body, thereby maintaining a stable inflation state of the object to be inflated.

The improved structure of the foregoing pressure relief valve comprises a body having a tubular shape and a pressure relief hole, a pressure adjusting member locked to the body and provided with a stop rubber, and a check valve Pieces. Wherein, the system has a sleeve inlet and an air outlet, a passage is provided between the inlet and outlet ports, and a top holding portion is arranged on the passage, so that the pressure adjusting member is sleeved on the air inlet, and the check member is locked Combined with the air outlet.俾 The air adjusting device is connected by the pressure adjusting member, and the air to be inflated is connected by the air outlet, and the pressure value (PSI, BAR) of the object to be inflated is set by the pressure adjusting member, so that the air pressure forms the inflation of the gas to be inflated through the passage, and is to be inflated. When the air pressure of the object reaches the pressure value, the feedback air pressure holds the anti-slip rubber of the pressure adjusting member, so that the air is released from the pressure releasing hole of the body, and then the check member is held at the step of the body passage. The inflated state in which the article to be inflated is maintained stable.

The improved structure of the pressure relief valve, wherein the passage of the body is provided with a flared tapered portion at the outlet end, and the check member is provided with a rod body, so that the rod body is disposed on a stopper. The stopper is locked to the air outlet, and the other end of the rod body is provided with a cone-shaped body, and the cone is provided with an O-ring, and a spring is inserted between the cone and the stopper to make the check piece It constitutes a movable state, and then the cone is blocked in the tapered section or by the tapered section to constitute normal airing or pressure relief.
