Abstract

The utility model relates to a kind of ball valves with memory return function, including valve body, valve rod, handle;Automatic reset device is mainly equipped in handle, the automatic reset device is made of reset spring, spring base and pull rod, spring base is fixedly connected on one end of handle, one end of pull rod is connect with the shaft on the valve body of valve rod side, the other end passes through spring base centre bore and extend into intracavity of handle, reset spring is helical spring, it is sleeved on the pull rod periphery of intracavity of handle, one end mounts elastically, the other end is fitted on pull rod by nut, baffle, spring base side is fixedly connected with one end of drive rod, and the other end of drive rod is fixedly connected with valve rod.After Manual operation handle opens or closes valve release handle, the valve that automatically resets avoids the safety accident forgotten to close after opening or forget to turn on generation after closing to initial position, good to pipe-line system safety guarantee performance.

Description

A kind of ball valve with memory return function
Technical field
The utility model belongs to valve field more particularly to a kind of ball valve.The utility model is suitable for normally opened or normally closed pipe Road valve.
Background technique
On the medium pipeline of certain special operation conditions, needs valve to be chronically at closed state or be chronically at opening state State needs to close in time after the operating condition Open valve that valve is chronically at closed state completes work, and locates for a long time in valve It is closed after valve completes work in the operating condition of open state and needs to open in time.The major defect of the prior art is: normal closed gate It opens and is easy to forget to close after completing work, normally opened valve is easy to forget to turn on after closing completion work, and pipe-line system is caused to produce Raw safety accident, product safety in utilization are poor.
Summary of the invention
The purpose of this utility model is to provide a kind of pair of pipe-line system safety guarantee for disadvantage of the existing technology The good ball valve with memory return function of energy.
The technical solution of the utility model includes valve body, valve rod, handle;Automatic reset device is mainly equipped in handle, The automatic reset device is made of reset spring, spring base and pull rod, and spring base is fixedly connected on one end of handle, pull rod One end is connect with the shaft on the valve body of valve rod side, and the other end passes through spring base centre bore and extend into intracavity of handle, reset spring For helical spring, it is sleeved on the pull rod periphery of intracavity of handle, one end mounts elastically, and the other end is by nut, baffle It is fitted on pull rod, spring base side is fixedly connected with one end of drive rod, and the other end of drive rod is fixedly connected with valve rod.
The utility model has the advantages that being equipped with automatic reset device in handle, valve is opened or closed in Manual operation handle After release handle, the valve that automatically resets is forgotten to close or forgets to turn on generation after closing to initial position after avoiding unlatching Safety accident is good to pipe-line system safety guarantee performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model is used in normally off.
Specific embodiment
Ball valve with memory return function as shown in Figure 1, including valve body 1, valve rod 2, spool, handle 3;In handle 3 Equipped with automatic reset device, the automatic reset device is made of reset spring 4, spring base 5 and pull rod 7, and spring base 5 is fixed to be connected It connects in one end of handle 3, one end of pull rod 7 is connect with the shaft 8 on 2 side valve body 1 of valve rod, and the other end passes through in spring base 5 Heart hole extend into 3 inner cavity of handle, and cooperation is moved between 5 centre bore of pull rod 7 and spring base, and reset spring 4 is helical spring, is sleeved on 7 periphery of pull rod of 3 inner cavity of handle, one end are mounted on spring base 5, and the other end is fitted on pull rod 7 by nut, baffle, 5 side of spring base is fixedly connected with one end of drive rod 6, and the other end of drive rod 6 is fixedly connected with valve rod 2.It is set in 2 two sides of valve rod There are open position block 10 and off-position block 9, when handle 3 rotates clockwise under external force, valve rod 2 revolves clockwise with movable valve plug Turn, Open valve, reset spring 4 is compressed;When handle 3 lays down external force, 4 pressure of reset spring effect under, make handle 3, Valve rod 2 and valve core reset, valve are automatically closed, and realize the normally closed memory return of spool position.For normally opened valve, by shaft The other side of valve rod 2 is arranged in 8 position.
