Abstract

The utility model relates to a clack film check valve which comprises a valve body (1), and a valve clack (2) located in the valve body (1). A pin shaft (3) is arranged on the valve body (1), and the valve clack (2) is movably connected with the pin shaft (3). The clack film check valve is characterized in that the valve body (1) and the valve clack (2) are made of rubber. Due to the fact that rubber which is used for making the valve body and the valve clack of the valve body has elasticity and flexibility, elasticity and flexibility of the check valve can be used for reducing and even eliminating pressure on the valve and a pipe wall from water flow when the valve is closed suddenly, and damage on a pipeline and the valve is avoided.

Description

A kind of valve safety check
Technical field
The utility model relates to a kind of valve safety check.
Background technique
The valve safety check is valve commonly used on a kind of fluid line, it is mainly used in preventing that the fluid in the pipeline from refluxing, cause the damage of equipment, the valve body of the safety check that adopts is metal material substantially at present, but in water (or other liquid) course of conveying, because valve is opened suddenly or is closed, water pump stops suddenly, suddenly open and close reasons such as stator, make flow velocity take place to change suddenly, fluid can be to valve and tube wall, mainly be that valve or pump can produce a pressure, be water hammer effect, the instantaneous pressure that is produced by water hammer can reach tens times hundreds of times even of proper functioning pressure in the pipeline.This fluctuation of pressure significantly can cause the pipe-line system judder, noise, and pressure is too high, also can cause breaking of pipe, and damages valve and fixed block, and pipe-line system is had very big destruction, has shortened equipment and has been to use the life-span.Therefore, be necessary to make improvements.
The model utility content
Technical problem to be solved in the utility model is, a kind of valve safety check is provided, and is simple in structure, economical and practical, avoids causing device damage because of water gravity.
The utility model is achieved in that the valve safety check, comprises valve body, is positioned at the flap of valve body, and valve body is provided with bearing pin, and flap is movably connected on the bearing pin, it is characterized in that described valve body and flap all adopt rubber to be made.Flap is by rotating around bearing pin, make fluid reach the purpose of non-return, when adopting rubber to make check valve body and flap, because rubber has elasticity and stretchability, can be by elasticity, the contraction of safety check, current have been avoided the damage of pipeline and valve to the pressure that valve and tube wall produce when slackening even eliminating valve and closing suddenly.
Described valve body is provided with the spring assembly that flap is resetted.
Described spring assembly is the fiber spring assembly.
Compared with prior art, the beneficial effects of the utility model are: because elasticity and stretchability that rubber itself has, adopt rubber to make valve body and the flap of safety check, not only guaranteed the sealing of safety check, and elasticity, expansion performance by safety check rubber material, slacken even eliminated current when valve is closed suddenly to the pressure that valve and tube wall produce, avoided the damage of pipeline and valve, be conducive to save cost.
Description of drawings
Fig. 1 is one of the utility model structural representation.
Fig. 2 is two of the utility model structural representation.
Embodiment
Reach embodiment by reference to the accompanying drawings down, the utility model is further elaborated.
As shown in Figure 1, the valve safety check comprises valve body 1, is positioned at the flap 2 of valve body 1, and valve body 1 is provided with bearing pin 3, and flap 2 is movably connected on the bearing pin 3, it is characterized in that described valve body 1 and flap 2 all adopt rubber to be made.
As shown in Figure 2, described valve body 1 is provided with the spring assembly 4 that flap 2 is resetted.
As shown in Figure 2, described spring assembly 4 is the fiber spring assembly.
When the valve closing on the pipeline, the pressure that fluid produces can be slackened by the safety check with elasticity and stretchability even be eliminated, thereby protection pipeline and valve are not damaged.

Claims (3)

1. valve safety check, comprise valve body (1), be positioned at the flap (2) of valve body (1), valve body (1) is provided with bearing pin (3), and flap (2) is movably connected on the bearing pin (3), it is characterized in that described valve body (1) and flap (2) all adopt rubber to be made.
2. a kind of valve safety check according to claim 1 is characterized in that described valve body (1) is provided with the spring assembly (4) that flap (2) is resetted.
