Example Embodiment

[0015] Example 1

[0016] This embodiment is a special combined pipe valve for phosphorus oxychloride source bottle. Phosphorus oxychloride is a colorless, transparent, corrosive and toxic liquid. Irritates mucous membranes and lungs after inhalation. Contact with skin can cause severe burns. Because phosphorus oxychloride is highly toxic and highly corrosive, the source bottle is made of quartz glass, and all pipe and valve parts are made of PTFE plastic. At this time, the gas pipe and pipe valve parts of the source bottle cannot be directly connected with threads. Practice has proved that due to the excellent lubricating performance of PTFE plastic, the ideal anti-pulling performance cannot be obtained when the pipe valve parts of the prior art are used - when the pipe valve parts, especially the external hose, are subject to pulling force, It is relatively easy to disengage from the gas tube of the source bottle or the side port of the valve body, so there is an unsafe f...

Abstract

The present invention relates to an improvement of structure of source bottle special-purpose combined pipe valve component, belonging to the field of chemical product pipeline sealed connection technology in IT industry. Said combined pipe valve component includes the following several portions: valve body lower locking cap which it tightly mounted on the source bottle gas pipe, two-way angle valve body whose lower port external screw-thread is screw-combined in internal screw-thread of valve body lower locking cap, valve core which is screw-mounted in described valve body from top to bottom, and valve port locking cap which is screw-turned in valve body side port and is used for locking hose. Its improved place lies in that the side port and lower port of the described valve body are respectively equipped with inwards-recessed cone hole whose external portion is large and internal portion is small, in the described cone hole a cone cover matched with said cone hole is inserted, and the external end face of the described cone cover and the bottom plane of internal screw-thread hole of the correspondent locking cap are flush-leveled.

Description

technical field [0001] The invention relates to a special combined pipe valve part, in particular to the structural improvement of a special combined pipe valve part for source bottles, and belongs to the technical field of sealed connection of chemical pipelines used in the IT industry. Background technique [0002] The source bottle used to hold toxic and dangerous chemicals such as phosphorus oxychloride is generally in the shape of a can, usually made of glass, with a substantially vertical air inlet pipe, air outlet pipe, and liquid filling pipe on the upper end. Neck groove. During use, a T-shaped pipe valve that can be connected to a flexible pipe must be installed on the inlet and outlet of liquid and gas. The pipe valve is mainly composed of the lower locking cap of the valve body tightly fitted on the source bottle, the two-way angle valve body whose lower end is screwed into the lower locking cap of the valve body, and screwed on the valve body from top to bottom...
