Abstract

The utility model relates to a locking valve which belongs to the field of the control of a lock and a pipeline. The locking valve is composed of a valve, a lock body, a lock core, a key, a friction buffering sheet, a pin and a spring. The rotation of a valve rod is limited through inserting the pin into a locking hole on the valve rod by making use of an inclined plane on the end surface of the lock core. The utility model has a locking position within every 180 DEG. When the valve is rotated, the key is inserted into the lock core and is rotated. The locking valve has the advantages of simple structure and reliable and convenient use. The utility model can be suitable for various valves.

Description

The locked type valve

The utility model is a kind of locked type valve, belongs to lock and pipeline control field.

Valve is as the pipeline controlling component, and everybody can control use.But, just need be controlled, and be used by the special messenger to its use for special place.As charge heating, water etc.Common valve is not possess these functions.Now, though more existing valves with lock, their most structure more complicated, cost is higher.

In order to carry a kind of simple in structure, easy to use, lockable valve that cost is low, the utility model spy has proposed a kind of locked type valve.

This practical locked type valve is to be made of valve, lock body, lock core, key, friction buffer sheet, pin and spring; The structure of this locked type valve is that the gland nut of valve and lock body are integral; Lock core hole is opened on lock body, is split into blind hole, and in the end of lock core hole, a pin hole is opened at eccentric position, communicates with valve lever; The end face of lock core is that an inclined-plane is loaded in the lock core hole, and pin cover upper spring is inserted in the locking nail hole, and the friction buffer sheet is equipped with in their centre, and it is a garden cylindricality pad; Have a through hole, i.e. locking aperture at valve lever corresponding to the position of pin hole.

The working method of this locked type valve: when the mode of locking, lock core relies on its inclined-plane, by the friction buffer sheet pin is released, and enters the locking aperture on the valve lever, makes valve not have to rotate per 180 ° of locking bits under the situation of key.When rotating valve, key is inserted lock core rotates because the end face of lock core is the inclined-plane, forward several angle to after, can abdicate certain space, under the effect of spring, pin withdraws from from locking aperture, at this moment, valve is free to rotate.This locked type valve simple in structure, easy to use and reliable, it is applicable to all kinds of valves.

Embodiment: (seeing Fig. 1,2)

This practical locked type valve is to be made of valve 1, lock body 2, lock core 3, key 4, friction buffer sheet 5, pin 6 and spring 7; The structure of this locked type valve is that the gland nut 8 with valve 1 is integral with lock body 2; Lock core hole is opened on lock body 2, is split into blind hole, and in the end of lock core hole, a pin hole is opened at eccentric position, communicates with valve lever 9; The end face of lock core 3 is that an inclined-plane is loaded in the lock core hole, and pin 6 cover upper springs 7 are inserted in the locking nail hole, and friction buffer sheet 5 is equipped with in their centre, and it is a garden cylindricality pad; Have a through hole, i.e. locking aperture at valve lever 9 corresponding to the position of pin hole.
