Improved structure of pressure relief valve

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

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. In view of this, the applicant has continued to study and experiment, and he has improved the improved structure of a pressure relief valve, so that when the inflated material reaches the set value, the air exceeding the set pressure value is released from the pressure relief hole, so that The inflator is stably maintained in an inflated state at a set pressure value, thereby making the inflation operation more convenient.

The main purpose 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 be inflated. When the inflation reaches the pressure value, the air exceeding the set pressure value is released from the pressure relief hole of the body, so that the to-be-inflated material is stably maintained in the inflated state of the set pressure value.

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 provided with a stop rubber, and a check member. Among them, the The system is provided with inlet and outlet ports, and has a small diameter passage between the inlet and outlet ports, and a through hole penetrating through the body is arranged in the passage, so that the pressure adjusting member is locked to the through hole, and the check member is locked Locked to the air outlet.俾 The air pump is connected to the air inlet of the body, and the air inlet is connected to the air to be inflated, and the pressure value of the object to be inflated is set by the pressure adjusting member. When the inflation pressure of the air to be inflated reaches the pressure value, the excess pressure is The anti-release rubber of the pressure adjusting member is lifted upward, so that the air exceeding the set pressure value is released from the pressure releasing hole of the body, and at the same time of releasing the pressure, the check member will be held on the passage of the body to form a non-reverse effect. Further, the object to be inflated is stably maintained in an inflated state of a set pressure value.

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 for locking the rod body to the elongated sheet body. The long piece 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 arranged between the cone and the elongated piece to stop The reverse member constitutes a movable state, thereby causing the cone to block or be detached from the passage to constitute normal airing or backstopping.

Please refer to the first and second figures at the same time, and in conjunction with the third figure, the three-dimensional exploded view and sectional view of the creation. As shown, the present invention comprises a tubular body 1, a pressure adjusting member 2, and a check member 3. The main body 1 is provided with an air inlet 11 and an air outlet 12 at two ends, and a step 121 is disposed at an appropriate position of the air outlet 12, and a passage of a smaller diameter is provided between the air inlet 11 and the air outlet 12. 13. The passage 13 is provided with a through hole 14 penetrating through the body and a small diameter air guiding hole 141. The through hole 14 is provided with a pressure releasing hole 15 penetrating through the wall surface of the body 1. The connecting end of the channel 13 and the air outlet 12 is A sleeve-shaped tapered portion 16 is provided; the pressure adjusting member 2 is provided with a sleeve 21, and a fixing seat 22 is disposed in the sleeve 21, and a stop rubber 23 is disposed under the fixing seat 22 for fixing A top holder 24 is disposed above the seat 22, and a spring 25 is disposed between the top holder 24 and the fixed seat 22. The top holder 24 is sleeved by a dial 26 to lock the dial 26 to the first The adjusting seat 27 is locked to the sleeve 21, and the sleeve 21 is locked to the through hole 14 of the body; the check member 3 is provided with a rod 31 for locking the rod body 31 to An elongated piece 32 locks the elongated piece 32 to the air outlet 12 of the body, and is positioned to prevent excessive locking by the step 121. The other end of the rod 31 is provided with a tapered body 33. An O-ring 34 is disposed on the tapered body 33, and a spring 35 is disposed between the tapered body 33 and the elongated body 32 to configure the check member 3 to be movable. By combining the members, a vent is formed. Pressure valve. When in use, the air pumping device 11 is connected to the air pumping device, and the air inlet 12 is connected to the air to be inflated, and the pressure adjusting member 2 is used to set the pressure value of the object to be inflated. Under normal conditions, the pressure is normal. The anti-slip rubber 23 of the adjusting member 2 is blocked by the spring 25 and the fixing seat 22 to be blocked in the air guiding hole 141 of the main body 1, so that the air of the air inflating device can push the non-returning member 3 toward the air outlet 12 to form an appropriate gap. The air passes through the check member 3 to constitute an inflation of the article to be inflated. When the inflated material reaches the pressure value, the excess air that continues to be driven by the air inlet 11 pushes the fixing seat 22 and the anti-slip rubber 23 of the pressure adjusting member 2 upward, and at this time, the anti-bleed rubber 23 is separated from the air guiding hole 141. The air is released from the pressure relief hole 15 of the body 1. When the air is released from the pressure relief hole 15 of the body 1, the cone 33 of the check member 3 is pulled by the pressure of the pressure release and the pressure of the spring 35. The tapered section 16 of the passage 13 of the body 1 forms a non-reversing effect, thereby maintaining the inflated body stably in an inflated state of the set pressure value.

Please refer to the fourth figure, which is a diagram of the inflated embodiment of the present creation.

The air is occluded in the air guiding hole 141 of the body 1 so that the air generated by the air inflating device directly passes through the passage 13 to push the check member 3 toward the air outlet 12, so that the tapered body 33 is separated from the tapered portion 16 of the passage 13 Forming a proper gap, since the elongated piece 32 of the check member 3 and the periphery of the air outlet 12 have a space, the air can pass through the space of the check member 3 and the elongated body 32 and the air outlet 12, The air outlet 12 is released to constitute an inflation of the article to be inflated.

Please refer to the fifth figure, which is a diagram of the pressure relief embodiment of this creation. As shown in the figure, when the to-be inflated material reaches the set pressure value, the excess air that the air inlet 11 continues to drive will hold the fixing seat 22 of the pressure adjusting member 2 and the stop rubber 23 upward, so as to stop the leakage. The rubber 23 is separated from the air guiding hole 141, and the air is released from the pressure releasing hole 15 of the body 1. When the air is released from the pressure releasing hole of the body 1, the cone 33 of the check member 3 is deflated. The pressure of the traction and the pressure of the spring 35 are held on the tapered section 16 of the passage 13 of the body 1, and the inflated body is stably maintained in the inflated state of the set pressure value.
