Problems solved by technology

[0002] Angle valves are tools used in the pipeline field. There are a large number of angle valves used for water stop or throttling on the market. Because angle valves need to exert a large force during installation, it is easy to cause damage to the material structure of the angle valve. The subsequent continuous use of the valve will cause the angle valve to age. In severe cases, the valve core will suddenly crack, break or even fall off. It is easy to leak a large amount of water without the knowledge of the consumer, flood the house, and endanger the property and personal safety of consumers.

Embodiment Construction

[0023] This application requests protection for a leak-proof water angle valve, such as figure 1 with 2 As shown, it includes a valve casing 600 arranged at right angles and a sleeve 100 housed in the valve casing 600, a piston rod 200 and a valve core 300. The valve casing 600 is detachably connected to the outside, and the sleeve 100 is arranged on the valve casing. The water inlet end of 600 has a stepped through hole 110. The water flow first enters from the outer hole of the stepped through hole 110 and then flows into the inner hole of the stepped through hole 110. The piston rod 200 is sleeved in the stepped through hole 110 and opposite to the sleeve. 100 telescopic movement, when the device is not in trouble, the water flows in from the gap between the sleeve 100 and the piston rod 200 to form the first water flow channel. The piston rod 200 is provided with a plug 210 and a connecting part 220 along the water inlet direction. The radial dimension of the head 210 is ...

Abstract

The invention discloses a water leakage prevention angle valve comprising a valve casing, a sleeve, a piston rod and a valve element. The valve casing is arranged in a right-angle manner. The sleeve,the piston rod and the valve element are contained in the valve casing. The valve casing and the outer portion are detachably connected. The sleeve is arranged at the water inlet end of the valve casing and comprises a stepped through hole. The piston rod is arranged in the stepped through hole in a sleeving manner and moves relative to the sleeve in a telescopic manner. A first water flow channelis formed by the gap between the sleeve and the piston rod. The piston rod is provided with a plug and a connection part in the water inflow direction. The outer hole size of the stepped through holeis larger than the inner hole size of the stepped through hole. The connection part is used for being connected with the valve element in a butt joint manner. The invention provides the water leakageprevention angle valve capable of automatically closing a water channel under the condition that the valve element cracks or breaks.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to an anti-leakage water angle valve. Background technique [0002] Angle valves are tools used in the pipeline field. There are a large number of angle valves used for water stop or throttling on the market. Because angle valves need to exert a large force during installation, it is easy to cause damage to the material structure of the angle valve. The subsequent continuous use of the valve will cause the angle valve to age. In severe cases, the valve core will suddenly crack, break or even fall off. It is easy to leak a large amount of water without the knowledge of the consumer, flood the house, and endanger the property and personal safety of consumers. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems mentioned above, and provides an anti-leakage water angle valve that automatically closes the water channel when the valve co...
