Abstract
The utility model relates to an aluminium alloy oxygen-valve air intake-mouth sealing device arranged on a high-pressure oxygen bottle which is applied to medical application or other occasions. The device comprises a valve body, wherein an inner cavity of the valve body is matched and connected with an air intake joint by screw threads; an intake-mouth position on the air intake joint is provided with an external joint which is pressed by a push threaded rod; the center of the air intake joint is provided with an air intake passage; the center part of the matching section of the air intake joint and the valve body is provided with a pressure measuring hole which is penetrated through the inner part and the outer part of the air intake joint. The utility model is characterized in that the matching section of the air intake joint and the valve body and the upper part and the lower part of the pressure measuring hole are respectively provided with O-shaped sealing rings which are sheathed at the periphery of the air intake joint. The utility model has the advantages of simple structure and high safety.
Description
Technical field
The utility model relates to the aluminum alloy oxygen valve suction port seal arrangement on a kind of high-pressure oxygen cylinder that is installed in medical or other applications.
Background technique
Existingly be installed in that oxygen valve suction port seal arrangement has generally comprised a valve body on the high-pressure oxygen cylinder, body cavity connects an air input joint by screw-thread fit, air input joint upper end inlet is provided with one by holding out against the external joint that screw mandrel compresses, at the air input joint center is gas-entered passageway, have a pressure tap inside and outside the perforation air input joint at air input joint with the section of the cooperation middle part of valve body, be used for communicating with oxygen manometer.The seal arrangement of this structure in use, when the moment of opening high-pressure oxygen cylinder, a high pressure draught part that is entered by external joint enters the gas-entered passageway at air input joint center, a part is flowed downward by the air input joint periphery, and this moment enter gas-entered passageway air-flow some flow to the periphery of air input joint from pressure tap, thereby make air input joint be with two strands of high pressure draughts outward instantaneous front bump takes place, cause temperature to rise rapidly, thereby exist the potential safety hazard of burning, exploding, poor stability.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure, the good aluminum alloy oxygen valve of Security suction port seal arrangement is provided.
Aluminum alloy oxygen valve suction port seal arrangement of the present utility model includes a valve body, body cavity connects an air input joint by screw-thread fit, air input joint upper end inlet is provided with one by holding out against the external joint that screw mandrel compresses, the air input joint center is a gas-entered passageway, have a pressure tap inside and outside the perforation air input joint at air input joint with the section of the cooperation middle part of valve body, it is characterized in that, in the cooperate section of air input joint, more than pressure tap, be respectively arranged with the O RunddichtringO that is enclosed within the air input joint periphery with following part with valve body.
The utility model is because at the upper and lower O RunddichtringO that is provided with of pressure tap, thereby two strands of high pressure draughts of air input joint periphery are isolated mutually and can not bump, avoid the burning of generation therefrom and the potential safety hazard of blast, improved the safety in utilization of device greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, the valve body 1 of this aluminum alloy oxygen valve suction port seal arrangement has one section section of cooperation with air input joint 2, cooperating the section middle part, have pressure tap 3 on the sidewall of air input joint, upper and lower at pressure tap, be respectively arranged with O RunddichtringO 4, the air input joint center is a gas-entered passageway 5, air input joint is provided with sealing gasket 6 with the section of the cooperation upper end of valve body, and external joint 7 is held out against screw mandrel 8 and is pressed on the sealing gasket.
