It is difficult to back-out in the bolt to get rusty, to increase the operation that staff dismantles valve rod, while existing gas safety drain valve
Often the scope of application is small with valve deck for door, and since different stem diameters is different, such a valve deck is often suitable for several valve rods,
It is small so as to cause the scope of application of valve deck.
Utility model content
The purpose of this utility model is to provide a kind of gas safety vent valves valve decks, to solve above-mentioned background technique
Middle proposition is inconvenient to back-out the small problem of range that fixed bolt is applicable in valve rod.
To achieve the above object, the utility model provides the following technical solutions: a kind of gas safety vent valves valve deck,
Including valve deck main body, the valve deck main body is internally provided with the first threaded hole, and the inside of first threaded hole passes through screw thread
It is connected with valve rod connecting tube, the second threaded hole and through-hole, the side of the through-hole have been extended through at the top of the valve deck main body
It is connected by connecting tube with the second threaded hole.
Preferably, the screw thread is adapted with the first threaded hole, and the valve rod connecting tube passes through screw thread and the first screw thread
Hole and valve deck main body dismantling connection.
Preferably, the outer surface of first threaded hole and the second threaded hole is coated with lubricating oil.
Preferably, second threaded hole and through-hole are provided with multiple, and multiple through-holes are enclosed in " annular array "
Around the second threaded hole.
Preferably, the connecting tube is provided with multiple, and direction of multiple connecting tubes along the second threaded hole tilts down.
Preferably, the making material of the valve deck main body includes stainless steel.
Compared with prior art, the utility model has the beneficial effects that this kind of gas safety vent valves are arranged with valve deck
There are connecting tube and through-hole, and the side of through-hole is connected with the second threaded hole with connecting tube by connecting tube along the second threaded hole
Direction tilt down, in this way when staff disassembly be fixed on the bolt in the second threaded hole when, staff first will lubrication
Oil pours into through-hole, and pouring into the lubricating oil in through-hole can be slid to the second threaded hole by connecting tube, thus the second screw thread of lubrication
Hole and fixed bolt can facilitate staff to back-out fixed spiral shell in this way so that staff be facilitated to back-out fixed bolt
Bolt, so that facilitating staff dismantles fixed valve rod, while this kind of gas safety vent valves are provided with first with valve deck
Threaded hole and screw thread, staff can be taken out valve rod connecting tube by the first threaded hole and screw thread from valve deck, further according to
Satisfactory valve rod connecting tube is installed back valve deck, such energy by screw thread and the first threaded hole by the model of the valve rod of connection
Valve rod connecting tube can be replaced, so that more valve rods be made to be suitable on the valve deck, improves the scope of application of the valve deck.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of gas safety vent valves valve deck, packet
Include valve deck main body 1, the first threaded hole 2, valve rod connecting tube 3, screw thread 4, the second threaded hole 5, through-hole 6 and connecting tube 7, the valve deck
Main body 1 is internally provided with the first threaded hole 2, and the inside of first threaded hole 2 is connected with valve rod connecting tube 3 by screw thread 4,
The top of the valve deck main body 1 has extended through the second threaded hole 5 and through-hole 6, first threaded hole 2 and the second threaded hole 5
Outer surface be coated with lubricating oil, in this way can using the first threaded hole 2 and the second threaded hole 5 it is more smooth, the through-hole 6
Side is connected by connecting tube 7 with the second threaded hole 5.
The screw thread 4 is adapted with the first threaded hole 2 referring to FIG. 1-2, and the valve rod connecting tube 3 passes through 4 He of screw thread
First threaded hole 2 and 1 dismantling connection of valve deck main body, can make the connection of screw thread 4 and the first threaded hole 2 closer in this way, and square
