Abstract
The utility model discloses a valve rod, which comprises a threaded segment (1), a polished rod part (2), and a part (3) connected with force applying components such as a valve handle and the like, wherein a tool withdrawal groove (4) is further formed between the threaded segment (1) and the polished rod part (2). Due to the adoption of the valve rod, thread rolling processing can be performed easily, and threaded segments with high mechanical properties can be obtained.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of worker's of being convenient to valve rod.
Background technique
Valve rod is one of key components and parts in the valve, and the thread section of valve rod is connected with valve sphere.Valve rod is at valve opening and close in the closed procedure, bear draw, pressure and twisting action power.So the mechanical property requirements to the screw thread position of threaded stem section is higher.The mode that at present double thread is handled in valve rod mainly contains screw thread rolled thread processing, effectively machining screw and make screw thread have higher intensity.But the structure of most of screw rod is not suitable for screw thread rolled thread processing, processes inconvenience.
The model utility content
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of valve rod of being convenient to screw thread rolled thread processing is provided.
For solving the problems of the technologies described above, concrete technological scheme of the present utility model is as follows:
Comprise thread section (1), polished rod position (2) and the position (3) that is connected with force application part such as valve handle, also comprise a tool withdrawal groove (4) between described thread section (1) and the polished rod part (2); The width of described tool withdrawal groove (4) is 4 ~ 12mm.
Further, the low 2 ~ 4mm of the depth ratio thread section core diameter of thread of described tool withdrawal groove.
Advantage of the present utility model is: of the present utility model rational in infrastructure, be convenient to carry out screw thread rolled thread processing, and satisfy the demand of its complex work occasion with the screw thread that obtains strong mechanical performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model valve rod can be divided into three parts, and the top is a thread section 1, and the valve sphere in all the other valves connects, the centre is a polished rod section 2, and afterbody 3 is for to be connected with the force application parts such as handle of valve; Tool withdrawal groove structure between thread section 1 and polished rod section 2.Valve rod is bearing pulling force in the opening and closing process of valve, pressure and twisting action power etc., stressed more complicated.And thread section 1 need satisfy high mechanical property requirements as connection part.This just need obtain the thread section 1 of strong mechanical performance to the processing method that adopts the screw thread rolled thread.Yet the structure that does not have tool withdrawal groove 4 on traditional valve rod makes especially at the screw-thread ending position, to be difficult to comparatively difficulty of rolled thread processing obtain high-quality screw thread and to meet the demands.The utility model is provided with a tool withdrawal groove 4 lower slightly than thread section 1 core diameter of thread, because the degree of depth is reasonable, guarantees not weaken the whole mechanical property of valve rod.Carrying out screw thread rolled thread first being processed, earlier the tool withdrawal groove cutting is being gone out.Make things convenient for rolled thread machining tool withdrawing, can make the screw thread of whole section high-quality simultaneously.
The utility model is simple and reasonable, under the prerequisite of the whole mechanical property of guaranteeing not weaken valve rod, is convenient to carry out screw thread rolled thread processing.
Claims (2)
1. valve rod comprises thread section (1), polished rod position (2) and the position (3) that is connected with force application part such as valve handle, also comprises a tool withdrawal groove (4) between described thread section (1) and the polished rod part (2); The width of described tool withdrawal groove (4) is 4 ~ 12mm.
2. valve rod according to claim 1 is characterized in that: the degree of depth of described tool withdrawal groove (4) is than the low 2 ~ 4mm of thread section (1) core diameter of thread.
