Description
Technical Field
The utility model belongs to a water pipe check valve device relates to a device for preventing water pipe rivers backward flow.
Background
Most of the existing closing modes of a valve with a check valve for blocking media from flowing backwards are a lifting type and a swing type; basically, a spring is needed to push the valve clack to close, and the problems of large resistance, poor sealing performance during closing and valve clamping of a muddy water pipe exist.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned cardinal number problem, the utility model aims at providing a device for preventing water pipe rivers backward flow makes it to avoid the defect that the check valve has the valve clack, develops a new style in addition, and the effectual poor problem of solution backward flow leakproofness improves work efficiency.
In order to achieve the above purpose, the purpose of the present invention is achieved by the following technical solutions:
a device for preventing backflow of water in a water pipe, the device having a threaded shell for connection to a water pipe of the same diameter; the water outlet end of the threaded shell is connected with a through hole joint; the through hole joint is provided with a plurality of water flow through holes; a spiral curve rotor is arranged in the threaded shell; the spiral curve rotor is elastically connected with the thread shell and can rotate relative to the thread shell; a plurality of curve pipes which have the same spiral direction with the spiral curve rotor are arranged in the spiral curve rotor; the arrangement of the curved pipe is the same as that of the water flow through holes on the through hole joint; the plurality of curve pipes are communicated with the through hole sections or separated from the through hole sections when rotating along with the spiral curve rotor relative to the thread shell; and a snap ring for preventing the spiral curve rotor from shifting and preventing sand from entering is arranged at the water inlet of the threaded shell.
The screw thread shell and the spiral curve rotor are connected into a whole through the connecting rod and the spring, and the spiral curve section can be pulled back by the spring after rotating.
The utility model provides a device for preventing water pipe rivers backward flow effectively solves the water pipe check valve and has the resistance big, and the leakproofness is poor when closing to and the problem of muddy water pipe strap valve, the control of being convenient for, simple to operate does not receive the condition restriction, can combine at will with ordinary pipeline, and can be used in the pipeline that has silt, be fit for using on a large scale.

Detailed Description
The method of the present invention is explained below with reference to the drawings.
As shown in fig. 1, 2, 3, and in conjunction with fig. 6, a device for preventing backflow of water in a water pipe, the device having a threaded housing 2 for attachment to a water pipe of the same diameter; the water outlet end of the threaded shell is connected with a through hole joint 1; the through hole section 1 is provided with a plurality of water flow through holes; a spiral curve rotor 3 is arranged in the threaded shell 2; the spiral curve rotor 3 is connected with the thread casing 1 through a spring 5, and the spiral curve rotor can rotate relative to the thread casing; the spiral curve rotor 3 and the threaded shell are connected together by the spring 5 through a connecting rod on the spring mounting hole 9 and a connecting rod on the groove 7, so that the spiral curve rotor 3 can be pulled back after rotating, and the pulled-back spiral curve rotor 3 and the through hole joint 1 form a cut-off state and a backflow stop state; a plurality of curve pipes 8 which have the same spiral direction with the spiral curve rotor are arranged in the spiral curve rotor 3; the arrangement of the plurality of curves 8 is the same as that of the plurality of water flow through holes on the through hole joint; the plurality of curve pipes are communicated with the through hole sections or separated from the through hole sections when rotating along with the spiral curve rotor relative to the thread shell; and a snap ring for preventing the spiral curve rotor from shifting and preventing sand from entering is arranged at the water inlet of the threaded shell.
The through hole joint 1 is welded with the water outlet of the thread shell 2, and after the spiral curve rotor 3 rotates, the hole on the through hole joint 1 is communicated with the curve pipe 8 on the spiral curve rotor 3 to form through flow.
The above description is presented to enable one of ordinary skill in the art to make and use the invention. Those skilled in the art can now make various modifications to the above description and apply the general principles of this disclosure to other examples without the use of inventive faculty. Therefore, it is intended that all such modifications and alterations be included within the scope of the present invention.
