Description
Technical field
The present invention relates to a kind of novel tamper-evident instrument block valves, belong to valve arrangement technical field.
Background technique
Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to apply to flap and press
Power is not leaked with forced seal face.When medium is by entering valve below flap, the resistance overcome required for operating force, is valve
The frictional force of bar and filler and the thrust as caused by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending otherwise can occur.It is divided into three kinds by connection type: flanged joint, screwed connection, welding
Connection.After the appearance of the valve of self-sealing, the medium flow direction of shut-off valve just changes by entering valve chamber above flap, at this moment in medium pressure
Under power effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile it being acted in medium
Under, the valve of this form is also relatively tight.
The opening and closing element of shut-off valve is the flap of stopper, and sealing is above in plane or the extra large conical surface, center line of the flap along valve seat
It is for linear motion.The forms of motion of valve rod, (adopted name: dark bar), also have lifting rotation rod-type can be used for controlling empty gas and water,
The flowing of the various types fluids such as steam, various corrosive medias, mud, oil product, liquid metal and radiating medium.Therefore,
Such shut-off valve valve that shuts off is highly suitable as cutting off or adjusting and throttling is used.Since the valve rod of such valve is opened
It opens or shutoff stroke is relatively short, and there is very reliable cutting function, and due to the variation of valve seat port and flap
Stroke direct proportionality is very suitable for the adjusting to flow.
Current shut-off valve all can not achieve tamper-evident function, and shut-off valve in use trembles frequent occurrence, to hold
Easily lead to noise and valve damage.
Summary of the invention
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, propose that one kind can effectively prevent shut-off valve
The novel tamper-evident instrument block valve of trembling.
The technical solution that the present invention proposes to solve above-mentioned technical problem is: a kind of novel tamper-evident instrument block valve,
Including valve body, spool and valve deck further include tamper-evident lower valve rod, tamper-evident upper valve rod and tamper-evident gland；Valve inner
Equipped with valve chamber, valve chamber is located at valve body center, and spool is arranged in the valve chamber of valve body；Valve deck is solid with valve body above valve chamber
It connects, tamper-evident gland is arranged above valve deck, and tamper-evident lower valve rod sequentially passes through tamper-evident gland and valve deck and valve
Core is affixed, and the gap between tamper-evident lower valve rod and valve deck is filled with filler, and valve deck is protruded into simultaneously in the lower end of tamper-evident gland
It is mutually abutted with the upper end of filler；The upper end of tamper-evident lower valve rod is formed with rectangle link block, the lower end system of tamper-evident upper valve rod
There is a rectangular recess to match with rectangle link block, tamper-evident upper valve rod passes through rectangular recess and rectangle link block
Cooperation is set in the upper end of tamper-evident lower valve rod.
The improvement of above-mentioned technical proposal is: the lower end of tamper-evident gland and the threaded upper ends of valve deck connect.
The improvement of above-mentioned technical proposal is: further including nut, nut is arranged between tamper-evident gland and valve deck；It is anti-
The lower end of tampering gland is provided with external screw thread, and nut is connect with the lower thread of tamper-evident gland, the lower end of nut
It is mutually abutted with the upper end of valve deck.
The improvement of above-mentioned technical proposal is: further including U-shape lock, the upper end side wall of tamper-evident gland offers lockhole, U
The U-shape lock ring of type lock passes through lockhole and mutually abuts with the side of tamper-evident lower valve rod.
The improvement of above-mentioned technical proposal is: the upper end of tamper-evident upper valve rod is connected with handle.
The beneficial effect of the present invention by adopting the above technical scheme is:
(1) stem design of integral type is split type, i.e., tamper-evident lower valve by novel tamper-evident instrument block valve of the invention
Bar and tamper-evident upper valve rod, efficiently solve integral type valve rod it is too long caused by shut-off valve tamper；Tamper-evident upper lower valve rod
The transmitting that valve switch torque is realized by the cooperation of rectangular recess and rectangle link block, according to the needs of instrument control, by instrument
After shut-off valve is set as standard-sized sheet or full off state, tamper-evident upper valve rod and handle are taken away and deposit in designated position, solves and cut
The only wobble problem of valve；
(2) threaded upper ends of the lower end of the tamper-evident gland of novel tamper-evident instrument block valve of the invention and valve deck connect
It connects, and is locked tamper-evident gland and valve deck by nut, effectively reduce the trembling of shut-off valve；
(3) novel tamper-evident instrument block valve of the invention further includes U-shape lock, and the upper end side wall of tamper-evident gland opens up
There is lockhole, the U-shape lock ring of U-shape lock passes through lockhole and mutually abuts with the side of tamper-evident lower valve rod, after having adjusted shut-off valve, leads to
The U-shape lock ring for crossing U-shape lock resists tamper-evident lower valve rod, and further effect reduces the trembling of shut-off valve.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings:
Fig. 1 is the structural schematic diagram of the novel tamper-evident instrument block valve of the embodiment of the present invention；
