Problems solved by technology

However, when the existing water stoppers are used, their sealing performance is usually difficult to meet the ideal requirements or standards. Correspondingly, water leakage may occur when the water stoppers are in use, which will have a negative impact on production and may lead to a decrease in product yield. decline

Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0016] see figure 1 , the embodiment of the present invention includes: a water stopper, including: a bolt body 1, a shrapnel 2, an O-ring 3 and a peg 4, a peg hole 5 is provided in the bolt body 1, and the peg hole 5 The mouth is provided with a chamfer, and the inclination of the chamfer is consistent with the inclination of the peg 4, which helps the peg 4 to fit closely with the peg hole 5.

[0017] The peg 4 is installed in the peg hole 5, and the shape of the peg 4 is trapezoidal. As the external temperature increases, the higher the temperature, the greater the pressure. The pressure of the peg 4 on the wall of the water stop The bigger, ...

Abstract

The invention discloses a water stop cock. The water stop cock comprises a cock body, an elastic sheet, an O-shaped ring and a cock screw, wherein a cock screw hole is formed in the cock body and is provided with a chamfer; the cock screw is mounted in the cock screw hole, and the shape of the cock screw is a trapezoid; the elastic sheet is mounted on the cock body and is of an unconnected circular ring; the O-shaped ring is mounted on the cock body and is made from water-swellable rubber. Through the manner, the water stop cock disclosed by the invention has no need of tooth tapping, never gets rusty, can be subjected to random tightness adjustment, has no need of a leakage stopping belt, can be moved randomly and be placed at any position in a water flow passage and is good in heat conductivity.

Description

technical field [0001] The invention relates to the field of molds, in particular to a water stop plug. Background technique [0002] The water stopper is a metal part used in the cooling or heating system of the mold water channel to fill the flow direction of the water channel. In order to effectively control the flow direction of the water channel, the industry puts forward higher requirements on the sealing performance of the water stop plug. In addition, whether the water stop plug can maintain effective sealing performance when it works in an environment of alternating cold and heat is also a test for checking the sealing performance of the water stop plug. An important criterion for whether the performance of the hydrant meets the requirements. However, when the existing water stoppers are used, their sealing performance is usually difficult to meet the ideal requirements or standards. Correspondingly, water leakage may occur when the water stoppers are in use, which...
