Description

Water filtering check valve with water saving function

Technical Field

The utility model relates to a check valve technical field specifically is a drainage check valve with water conservation function.

Background

The check valve, the one-way valve and the check valve are different names of valves and have the functions of preventing fluid from flowing backwards in a pipeline, the common check valve is mostly used in water heating, and the check valve is mostly arranged at the outlet of a water pump, so that water in a pipeline cannot flow backwards when the pump is stopped; the overhead check valve that also has of the suction pipe of water pump, just so can keep can the water-feeding when starting next time, and common check valve has spring, over-and-under type and swing formula, also uses the check valve in the hydraulic pressure, can be to hydraulic system holding pressure, and current check valve is in the use, goes out to be provided with the filter screen at the water inlet and filters the water that gets into, prevents that the impurity of aquatic from causing the jam to the check valve.

In-process using the check valve, the inside fixing base that is fixed with of valve body, fixing base one side is provided with mounting panel and baffle, be connected with the spring between mounting panel and the baffle, when rivers enter through the inlet port, rivers promote the baffle and carry out the displacement, the spring receives extrusion deformation simultaneously, baffle displacement cancellation is to the sheltering from of fixing base inner wall, rivers pass the inner wall of fixing base and discharge from the delivery port, when the water inlet stops intaking, the baffle is hugged closely with the fixing base by spring elastic force effect displacement, shelter from the inner wall of fixing base, thereby prevent that water from flowing toward the direction of water inlet from the direction of delivery port.

However, the spring is after using for a long time and accomplishing, the spring is ageing easily, cause the spring reset effect poor, cause the influence to the sealed of baffle, water passes the baffle easily and flows out, and then make the waste of water, be difficult to practice thrift this part of water, for avoiding the waste of water, need change the check valve, it is extravagant to wholly change, when changing the spring alone, need use tools to unpack the end cover of check valve apart, later reuse tools change the spring after taking out inside part one by one again, the operation is comparatively complicated, consequently, a drainage check valve with water conservation function is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the problem that the spring inside the check valve is difficult to replace alone, a water filtering check valve with a water saving function is provided.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a drainage check valve with water conservation function, includes the valve body, the both ends of valve body all are connected with connecting tube, the inner wall one end of valve body is provided with filter equipment, the inner wall fixedly connected with fixing base of valve body, the inner wall of valve body is located the one end of fixing base is provided with the mounting panel, the mounting panel orientation the one end of fixing base is provided with the baffle, the outer wall fixedly connected with movable rod of baffle, the baffle with be located between the mounting panel the outer wall connection of movable rod has the spring, the inside and the outer wall of valve body are provided with coupling mechanism, coupling mechanism includes mounting groove and installation piece, the mounting groove is seted up in the inside of valve body, installation piece fixed connection in the top and the bottom of mounting panel.
