Abstract

The utility model discloses a check valve, including valve body, water inlet, delivery port, check valve board, the water inlet of valve body install the inlet tube, the delivery port of valve body install the outlet pipe, the valve body have an expanded inner chamber, the inner chamber of valve body install the check valve board, the check valve board can the free rotation, the inner chamber of valve body be close to water inlet one side and install round rubber pad, the round valve plate that makes for the rigid material of check valve board, the check valve board connect in the inner chamber of valve body through the pivot, rubber pad pass through glue or glue the point bonding on the inner chamber wall of valve body, generally, the utility model has the advantages of production simple process is convenient for install and use, and is sealed of high quality, can effectively prevent the refluence of pipeline water -logging.

Description

A kind of check-valves

Technical field

This utility model belongs to pipe transportation technology field, relates to a kind of valve, particularly a kind of check-valves.

Background technology

Check-valves refers to rely on medium itself to flow and automatic open and close flap, is used for the valve preventing medium from flowing backwards, also known as check Valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, its Main Function be prevent medium from flowing backwards, Prevent pump and drive motor reversion, and the releasing of vessel media.The check valve design being presently used for preventing aqueous reflux is loaded down with trivial details, Cost is high, complex manufacturing, and airtight quality is the most unstable.Therefore, need a kind of production technology badly simple, cheap, Airtight quality is good, can effectively stop the check-valves of the refluence of water in pipeline.

Summary of the invention

The purpose of this utility model is to provide a kind of check-valves, and this check-valves production technology is simple, it is simple to install and use, economical Rationally, valve plate is closed tight, and good sealing effect has high use value.

The purpose of this utility model is achieved in that a kind of check-valves, including valve body, water inlet, outlet, check valve plate, The water inlet of described valve body is provided with water inlet pipe, and the outlet of described valve body is provided with outlet pipe, and described valve body has one The inner chamber expanded, the inner chamber of described valve body is provided with check valve plate, and check valve plate can be freely rotatable, described valve body interior Chamber is provided with a circle rubber cushion blocks near water inlet side.

Described check valve plate is the circular valve plate that rigid material is made.

Described check valve plate is connected to the inner chamber of valve body by rotating shaft.

Described rubber cushion blocks passes through glue or glue point bonding on the internal chamber wall of valve body.

This utility model produces and provides the benefit that: a kind of check-valves, including valve body, water inlet, outlet, check valve plate, Having check valve plate in the inflation lumen of valve body, check valve plate only allows water to enter from outlet discharge from water inlet, if in pipeline Aqueous reflux time, water will touch check valve plate, check valve plate to water inlet direction rotate, then check valve plate can touch rubber Rubber cushion block, check valve plate is tightly attached on rubber cushion blocks under the pressure of refluence water, thus effectively stops the refluence of water.

In figure: 1, valve body 2, water inlet 3, outlet 4, check valve plate 5, rotating shaft 6, rubber cushion blocks 7, water Flow path direction.

Detailed description of the invention

Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.

Embodiment 1

As illustrated in the accompanying drawings from 1 to 3, a kind of check-valves, including valve body 1, water inlet 2, outlet 3, check valve plate 4, described The water inlet 2 of valve body 1 is provided with water inlet pipe, and the outlet 3 of described valve body 1 is provided with outlet pipe, and described valve body 1 has One inner chamber expanded, the inner chamber of described valve body is provided with check valve plate 4, and check valve plate 4 can be freely rotatable, described The inner chamber of valve body 1 is provided with a circle rubber cushion blocks 6 near water inlet 2 side.

The circular valve plate that described check valve plate 4 is made for rigid material.

Described check valve plate 4 is connected to the inner chamber of valve body 1 by rotating shaft 5.

Described rubber cushion blocks 6 passes through glue or glue point bonding on the internal chamber wall of valve body 1.

This utility model is in use: a kind of check-valves, and water inlet connects water inlet pipe, and outlet connects outlet pipe, valve body There is the inner chamber of an expansion at middle part, is provided with the check valve plate that can rotate in inner chamber, is being provided with a circle rubber near water inlet side Cushion block, rubber cushion blocks plays the effect of buffering and seal washer.When water flows into valve body from water inlet it is, the sealing valve plate in valve body Under the effect of current hydraulic pressure, it is in the state of unlatching, makes current pass through valve body；When current adverse current, the water meeting of adverse current Touching sealing valve plate, sealing valve plate rotates under the effect of counter-flow water, and rubber cushion blocks is in close contact, and automatically closes, and reaches resistance The purpose that sealing stream flows backwards.

Generally, to have production technology simple for this utility model, it is simple to installing and using, airtight quality is good, can effectively stop pipeline The advantage of the refluence of interior water.
