Abstract
The utility model discloses a stop valve is from lock -switch, including valve body and valve rod, the inner chamber bottom fixed mounting of valve body has from the lock -switch, the top fixed mounting of valve body has the valve gap, and the middle part of this valve gap has seted up the passageway, and the top of this passageway is provided with valve -stem nut, the passageway on the valve gap is passed to the bottom of valve rod to be connected with the case in extending to the inner chamber of valve body, and this case lies in directly over the lock -switch, the top of valve rod and the welding of the bottom of valve rod screw thread post, and this valve rod screw thread capital end passes valve -stem nut to extend to valve -stem nut's the top and the bottom fixed connection of hand wheel. This stop valve is from lock -switch reasonable in design, convenient to use reciprocates through the hand wheel drive case, accomplishes from the opening and close of lock -switch, and is simple and efficient to handle, simple structure in addition, low in production cost, the assembly is easy, difficult wearing and tearing, long service life.
Description
Technical field
This utility model relates to self-lock switch technical field, is specially a kind of stop valve self-lock switch.
Background technology
At present, its structure of 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 switching self-locking and generally use and realized at button by switch lock hook is directly enough, this
The self-lock switch of kind of structure, latch hook easily frays button, affects performance, and structure is complicated after for a long time, and production cost is high, and assembling is compared
More difficult, especially switch by microminiature, produce, assemble and the most more bother, and easy to wear, service life is short, then we
A kind of stop valve self-lock switch is proposed.
Utility model content
The purpose of this utility model is to provide a kind of stop valve self-lock switch, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of stop valve self-lock switch, including valve body
And valve rod, the intracavity bottom of described valve body is installed with self-lock switch, and the top of described valve body is installed with valve gap, and should
The middle part of valve gap offers passage, and this passage be provided above valve stem nut, the bottom of described valve rod is through on valve gap
Passage, and extend to the inner chamber of valve body is connected with spool, and this spool is positioned at the surface of self-lock switch, described valve rod
Top is welded with the bottom of threaded stem post, and this threaded stem capital end is through valve stem nut, and extends to valve stem nut
The bottom of top and handwheel fixing be connected.
Preferably, described valve gap is fixedly mounted on the top of valve body by the clamping screw of its both sides, and valve gap and valve body
Junction be provided with seal washer.
Preferably, described valve stem nut is fixedly mounted on the top of valve gap by the arc torr of its both sides.
Preferably, between described valve rod and the sidewall of passage, bearing is installed.
Compared with prior art, the beneficial effects of the utility model are: this stop valve self-lock switch is reasonable in design, user
Just, drive spool to move up and down by handwheel, complete the keying to self-lock switch, simple and efficient to handle, and simple in construction, raw
Producing low cost, easily, the most easy to wear, service life is long in assembling.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 valve body, 2 valve gaps, 3 clamping screws, 4 valve rods, 5 spools, 6 self-lock switchs, 7 passages, 8 seal washers, 9 axles
Hold, 10 threaded stem posts, 11 valve stem nuts, 12 handwheels, 13 arc torr.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of technical scheme of this utility model offer: a kind of stop valve self-lock switch, including valve body 1 and valve
Bar 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 gap 2, and valve gap 2 is by it
The clamping screw 3 of both sides is fixedly mounted on the top of valve body 1, and the junction of valve gap 2 and valve body 1 is provided with seal washer 8, and
The middle part of this valve gap 2 offers passage 7, and this passage 7 be provided above valve stem nut 11, valve stem nut 11 is by its both sides
Arc torr 13 be fixedly mounted on the top of valve gap 2, the bottom of valve rod 4 is through the passage 7 on valve gap 2, and extends to valve body 1
Inner chamber in be connected with spool 5, bearing 9 is installed between the sidewall of valve rod 4 and passage 7, the setting of bearing 9 can reduce valve rod
Frictional force between 4 and passage 7 sidewall, decreases the abrasion of valve rod 4, and this spool 5 is positioned at the surface of self-lock switch 6, valve
The top of bar 4 is welded with the bottom of threaded stem post 10, and this threaded stem post 10 top is through valve stem nut 11, and extends
Fix be connected to the top of valve stem nut 11 and the bottom of handwheel 12, drive valve rod 4 leading to along valve gap 2 by rotation handwheel 12
Road 7 moves up and down, and drives spool 5 to open and close self-lock switch 6.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
