Description
Technical field
The invention belongs to valves, more specifically to a kind of gate valve of tool opening and closing situation instruction function.
Background technique
Existing gate valve does not have tool opening and closing situation and indicates function, and gate valve is often required that in actual production has this function
Can, when surprisingly stopping to convey such as the upstream of logistics system, liquid outflow has been can't see in downstream, gate valve in the open state, easily
It is mistaken for being being in close state, so that the pass is not related to, once, conveying is restored in upstream, safety accident is often wasted or occurs,
In addition, when multiple stream tubes respectively convey liquid material to same reactor with the flow of setting, understanding in chemical industry production
The opening and closing situation of gate valve is even more necessity in each stream tube.
Therefore it provides a kind of gate valve of tool opening and closing situation instruction function, has a very important significance.
Summary of the invention
A kind of gate valve of tool opening and closing situation instruction function of the present invention, including rotary handwheel, valve body, valve deck, flashboard, valve
There is upward and downward perforation at bar, filler clamp nut, latex ring, bellows, the valve rod center, and in the handwheel and the compression
The sliding slot of the laterally excessively described perforation is provided between nut, the perforation is inserted with elevating lever, and the elevating lever lower end connects the lock
Board bottom end, upper end connect a cross bar, and the lower end of the valve rod is provided with circular recess, the latex around the perforation
Ring upward and downward integration is alternatively formed the thin-walled and heavy wall of elevating lever described in several rings, and the latex ring makes the elevating lever tight
It is close pass through after, the upper end is closely plugged in the recess, and the bellows upper end connects the cross bar, and lower end connects the pressure
The peripheral wall of tight nut, the bellows is provided with hole, and when the flashboard rises to highest order, the bellows is in full exhibition state, and
The hole shows round shape.
The method have the advantages that:
By means of the shape that the hole is presented, intuitively reflect the opening and closing situation of the gate valve.
Detailed description of the invention
Fig. 1 is a kind of unlatching state structural schematic diagram for the gate valve for having opening and closing situation instruction function of the present invention.
Fig. 2 is a kind of closing state structural schematic diagram for the gate valve for having opening and closing situation instruction function of the present invention.
Fig. 3 is heretofore described latex ring and the elevating lever, the combination effect diagram between the valve rod.
Specific embodiment
The invention will be further described with reference to the accompanying drawing.
Fig. 1 or Fig. 2, shown in Fig. 3, a kind of gate valve of tool opening and closing situation instruction function, including rotary handwheel 1, valve body 2,
There is upward and downward perforation 9 at valve deck 3, flashboard 4, valve rod 5, filler clamp nut 6, latex ring 7, bellows 8,5 center of valve rod, and
The sliding slot 10 of the laterally excessively described perforation 9 is provided between the handwheel 1 and the clamp nut 6, the perforation 9 is inserted with elevating lever
11,11 lower end of elevating lever connects 4 bottom end of flashboard, and upper end connects a cross bar 12, and the lower end of the valve rod 5 is described
Circular recess 13 is provided with around perforation 9, the 7 upward and downward integration of latex ring has been alternatively formed elevating lever described in several rings
11 thin-walled and heavy wall, after the latex ring 7 allows the elevating lever 11 closely to pass through, the upper end is closely plugged on the recess 13
Interior, 8 upper end of bellows connects the cross bar 12, and lower end connects the clamp nut 6, the peripheral wall setting of the bellows 8
There is hole 14, when the flashboard 4 rises to highest order, the bellows 8 is in full exhibition state, and the hole 14 shows round shape.
It is in full reduced state at the bellows 8, the hole 14 shows flat slot, when described when the flashboard 4 minimizes
When the lifting of flashboard 4 is between highest order and lowest order, then 8 part of the bellows exhibition or contracting, the hole 14 shows ellipticity.Borrow
The shape that the hole 14 is presented, intuitively reflects the open/close states of the gate valve.
Each walled thickness in the latex ring is 0.3-0.8 millimeters, and distance is 1.2-1.8 millimeters between two heavy walls.
The latex ring 7 has several thin-walleds, then liquid material pressure of 7 lower part of latex ring in the valve body 2 is made
Under, it can be adjacent to the elevating lever 11 always, prevent liquid material from leaking out upwards between the valve rod 5 and the elevating lever 11.
The latex ring 7 is then difficult to ensure close between the latex ring 7 and the elevating lever 11, influence such as without thin-walled
Sealing effect, the thin-walled is single in this way, then can contract wrinkle when the elevating lever 11 is in lifting, influences the latex ring 7 and uses
In the service life, the thin-walled is several in this way, then because being stopped by each heavy wall above and below thin-walled when the elevating lever 11 is gone up and down, makes contracting wrinkle very
It is limited.
