Valve rod is valve important component, for being driven, Shang Jie executing agencies or handle, directly below band movable valve plug move
Or rotate, to realize valve switch or adjustment effect.The valve rod of panel valve in the market all carries escape, valve
Bar not still movement parts, stressed member during valve opening and closing, and be seal, valve rod under external force, is often being moved back
The place of cutter groove is broken.Meanwhile, it can also medium impact and corrosion.
A kind of valve rod (Application No. CN203796997U) of patent discloses a kind of valve rod, and it includes the valve of global formation
The body of rod, the lower end of valve-rod body is set to thread segment, and the head indent of the valve-rod body is in rectangular configuration, the valve rod of the rectangular configuration
The mounting hole through rectangular head is offered on body head;The upper end of the valve-rod body is provided with annular positioning groove.This valve rod
Although global formation intensity preferably, is appointed in use is so easier to abrasion, the phenomenon of corrosion.
Utility model content
The purpose of this utility model is to provide a kind of valve rod, can solve the problems, such as valve stem crack, corrosion.
The utility model provides following technical scheme:A kind of valve rod, including the body of rod, the body of rod by first body of rod and
Second body of rod is constituted, and first body of rod bottom is provided with thread segment, and the second body of rod top is provided with fixed part, first body of rod
Cross section is provided with for transition slightly larger than the cross section of second body of rod between first body of rod and second body of rod
Conical section;The fixed part top is provided with oil filler point, and first body of rod and second body of rod are equipped with going out of being connected with oil filler point
Oilhole;It is provided with horizontal trapped fuel groove on first body of rod and the second body of rod outer wall, the trapped fuel groove was around the body of rod one week.
Preferably, the oil outlet is arranged in trapped fuel groove.
Preferably, the oil outlet sets the adjacent position in trapped fuel groove top.
Preferably, the rod body material is carbon steel, can be in normal work under high-temperature and high-pressure conditions.
Preferably, the fixed part top is additionally provided with mounting hole.
Preferably, the thread segment top is provided with spacing ring.
Preferably, the depth of the trapped fuel groove is 2 to 4 millimeters.
The beneficial effects of the utility model are:The utility model provides a kind of valve rod, escape setting is eliminated, by bar
Connected with conical section between body, strengthen the intensity of valve rod, valve rod is provided with oil filler point and trapped fuel groove, and lubricating oil can be allowed to enter
To valve rod corrosion between valve body and valve rod, is prevented, the abrasion between valve rod and valve body is also reduced.
Brief description of the drawings
Accompanying drawing is used for providing being further understood to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model valve rod.
Specific embodiment
As shown in figure 1, a kind of valve rod, including the body of rod 1, the body of rod 1 is made up of first body of rod 11 and second body of rod 12, first
The bottom of the body of rod 11 is provided with thread segment 2, and thread segment 2 is used to be connected with valve element (not shown), and the top of second body of rod 12 is provided with
Fixed part 3 for installing handwheel, the cross section of first body of rod 11 slightly larger than second body of rod 12 cross section, first body of rod 11 with
The conical section for transition is provided between second body of rod 12;The top of fixed part 3 is provided with oil filler point 4, first body of rod 11 and the second bar
Body 12 is equipped with the oil outlet 5 connected with oil filler point 4;Horizontal trapped fuel groove is provided with first body of rod 11 and the outer wall of second body of rod 12
6, the trapped fuel groove 6 was around the body of rod 1 one weeks.Oil outlet 5 is arranged in trapped fuel groove 6.
Oil outlet 5 can also set the adjacent position in the top of trapped fuel groove 6, so it is also ensured that the profit of the outflow of oil outlet 5
Lubricating oil is flowed into trapped fuel groove 6, and the depth of trapped fuel groove 6 should not be too deep, and otherwise lubricating oil cannot give full play to, also should not be too shallow, no
Then deposit incessantly lubricating oil.So the depth of trapped fuel groove is 2 to 4 millimeters.
The material of the body of rod 1 is preferably carbon steel, can be in normal work under high-temperature and high-pressure conditions.The top of fixed part 3 is additionally provided with peace
Dress hole 8.Further improve, the top of thread segment 2 is provided with spacing ring 7, the setting of spacing ring 7 can limit threaded stem section 2 and load
Length in valve element, it is ensured that the positional precision between valve rod 1 and valve element and valve body.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, although ginseng
The utility model is described in detail according to previous embodiment, for a person skilled in the art, it still can be with
Technical scheme described in foregoing embodiments is modified, or equivalent is carried out to which part technical characteristic.It is all
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this practicality
Within new protection domain.
