Technical field
The present invention relates to self-lock switch technical field, specially a kind of shut-off valve self-lock switch.
Background technology
At present, its construction of well known self-lock switch is typically all by terminal contact, contact flat spring, button or push button, metal
Spring, latch hook and shell composition carry out being realized by switch lock hook directly enough in button for switch self-locking generally use, this
The self-lock switch of kind of structure, latch hook easily fray button, and with performance is influenced, and complicated after long, production cost is high, assembles ratio
It is more difficult, especially switched with microminiature, produce, assemble just more troublesome and easy to wear, service life is short, then we
It is proposed a kind of shut-off valve self-lock switch.
Invention content
The purpose of the present invention is to provide a kind of shut-off valve self-lock switch, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides following technical solution：A kind of shut-off valve self-lock switch, including valve body and valve
Bar, the intracavity bottom of the valve body are installed with self-lock switch, valve deck, and the valve deck are installed at the top of the valve body
Middle part offer channel, and valve stem nut is provided with above the channel, the bottom end of the valve rod passes through the channel on valve deck,
And it extends in the inner cavity of valve body and is connect with spool, and the spool is located at the surface of self-lock switch, the top of the valve rod
It is welded with the bottom end of threaded stem column, and the threaded stem top end passes through valve stem nut, and extends to the upper of valve stem nut
Side is fixedly connected with the bottom of handwheel.
Preferably, the valve deck is fixedly mounted on the top of valve body, and valve deck and valve body by the clamping screw of its both sides
Junction be provided with seal washer.
Preferably, the valve stem nut is fixedly mounted on the top of valve deck by the arc support of its both sides.
Preferably, bearing is installed between the valve rod and the side wall of channel.
Compared with prior art, the beneficial effects of the invention are as follows：The shut-off valve self-lock switch reasonable design, it is easy to use,
Spool is driven to move up and down by handwheel, complete the keying to self-lock switch, simple and efficient to handle and simple in structure, production
At low cost, assembling is easy, and not easy to wear, service life is long.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1 valve body, 2 valve decks, 3 clamping screws, 4 valve rods, 5 spools, 6 self-lock switch, 7 channels, 8 seal washers, 9 axis
Hold, 10 threaded stem columns, 11 valve stem nuts, 12 handwheels, 13 arc supports.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of shut-off valve self-lock switch, including valve body 1 and valve rod 4,
The intracavity bottom of valve body 1 is installed with self-lock switch 6, and the top of valve body 1 is installed with valve deck 2, and valve deck 2 passes through its both sides
Clamping screw 3 be fixedly mounted on the top of valve body 1, and valve deck 2 and the junction of valve body 1 are provided with seal washer 8, and the valve
The middle part of lid 2 offers channel 7, and the top of the channel 7 is provided with valve stem nut 11, the arc that valve stem nut 11 passes through its both sides
Shape support 13 is fixedly mounted on the top of valve deck 2, and the bottom end of valve rod 4 passes through the channel 7 on valve deck 2, and extends to the interior of valve body 1
Connect in chamber with spool 5, bearing 9 be installed between the side wall of valve rod 4 and channel 7, the setting of bearing 9 can reduce valve rod 4 with
Frictional force between 7 side wall of channel reduces the abrasion of valve rod 4, and the spool 5 is located at the surface of self-lock switch 6, valve rod 4
The bottom end of top and threaded stem column 10 weld, and 10 top of threaded stem column passes through valve stem nut 11, and extends to
The top of valve stem nut 11 is fixedly connected with the bottom of handwheel 12, by rotating 12 driving stem 4 of handwheel along the channel on valve deck 2
7 move up and down, and driving spool 5 opens and closes self-lock switch 6.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
