Description
Technical field
It the utility model is related to gate valve technical field, more particularly to a kind of novel magnetic locking gate valve.
Background technology
Magnetic lockable gate valve is widely used in each pipeline transportation of various industries, by private key hand off or is connect
Logical medium.Between the valve rod and gland of the magnetic lockable gate valve of in the market existing structure formed by the way of positioning pin
Be relatively fixed connection, so during opening and closing gate valve, twist gland band ovable valve stem rotate when, at this moment between the two it is direct by
Force is concentrated on positioning pin, therefore is easy to cause opening times increase and is caused to come off, and can also make both gland and positioning pin
Bearing produces gap, so as to cause the probability of trouble and increase maintenance during to use and replace the cost of accessory；
Mostly do not increase sealing structure further using being threadedly coupled between the valve body and valve deck of existing magnetic lockable gate valve, but
It is particularly important that sealing between the two；Magnetic lockable gate valve is when needing Open valve, upper magnetic steel and pressure in key unlock pin hole
The magnetic pole of lower magnetic steel in lid is homopolarity, and under the action of magnetic homopolarity mutually repels, lower magnetic steel produces locating detent and spring
Pressure makes locating detent be entirely retracted in the positioning lockhole of valve deck so that bonnet, can be rotated with key turn is opened, then
Rotated with ovable valve stem and realize the open and close of valve body, but the latch bore dia of key is more than on valve deck and positions the straight of lockhole
Footpath, after lower magnetic steel is pressed into and to be unlocked in positioning lockhole by upper magnetic steel, during twisting lower magnetic steel and locating detent with
And still plane-plane contact forms frictional force between the upper surface of valve deck, so as to increase the force of magnetic lockable gate valve opening-closing process；
The magnetic lockable gate valve of existing in the market existing structure twist opening mode have it is following：Usually card is being provided with the key
Sell, card slot be provided with gland, only have the cooperation of bayonet lock and card slot to twist not other auxiliary between key and gland and connect,
Key skids relative to valve deck and causes key to come off so during use；Also be exactly offer on the key with
The matched polygon of valve rod twists hole, a diameter of 15mm of market upper valve rod maximum, and aperture due to valve rod and on the key
Size matches, and key has specificity, and can be opened plus instrument in valve deck upper surface two blocks of magnet steel of placement, so
Safe antitheft is very poor, so needing a kind of effectively to prevent that key from coming off while safe key applied widely.
The content of the invention
The utility model provide in view of the above-mentioned problems existing in the prior art a kind of service life is long, laborsaving, leakproofness more
Good, safe, easy to use novel magnetic locking gate valve.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of novel magnetic locking gate valve, including valve
Body, the valve deck being fastened on valve body, valve rod, flashboard, the gland and key assembly being arranged on valve deck；During valve deck is provided with
