Abstract
The utility model discloses a high performance manual stop valve which comprises a rotary handle and a valve rod. The utility model is characterized in that the lower end of the valve rod is provided with a longitudinal guide device which prevents the valve handle from rotating, the upper end of the valve rod is connected with rotary handle through screw threads and the rotary handle is fixed to the upper end of a supporter of the high performance manual stop valve through one end surface bearing. When the stop valve is opened or closed, the rotary handle is rotated, and the valve rod is limited by the longitudinal guide device and can not make rotary motion. The screw threads between the rotary handle and the upper end of the valve rod cause the valve rod to move up and down. When the valve rod moves up and down, the valve rod can not rotate and the bottom abrasion of the valve rod can be reduced. The service life of the valve can be extended, and the torque which is required to rotate the rotary handle can be reduced.
Description
Technical field
The utility model relates to a kind of valve, specifically, relates to a kind of high-performance hand stop valve.
Background technique
Traditional stop valve, rotatable handle are directly connected on the valve rod, and during keying, rotatable handle drives valve rod and rotates together, by the screw thread that matches with valve rod on the support valve rod is moved up and down.Like this, stop valve moves up and down on one side valve rod drives spool when opening and closing, Yi Bian oneself rotates, has quickened the wearing and tearing of filler and seal spool sheet, thereby the life-span that stop valve uses is lower.
Summary of the invention
Goal of the invention of the present utility model is to overcome above-mentioned deficiency, and long high-performance hand stop valve of a kind of wear-resistant, life-span is provided.
For achieving the above object, the utility model high-performance hand stop valve comprises rotatable handle, valve rod, has one to prevent the longitudinal guide that valve rod rotates in the valve rod lower end, and the valve rod upper end is connected with rotatable handle by screw thread.
In addition, further reduce to rotate the required moment of rotatable handle, rotatable handle is fixing by the support upper end of an end face bearing and high-performance hand stop valve.
When opening and closing stop valve, rotate rotatable handle, valve rod is subjected to the restriction of longitudinal guide, can not rotation motion; Rotatable handle by and valve rod upper end between screw thread valve rod is moved up and down.Valve rod can not rotate when moving up and down again, has reduced the wearing and tearing of valve rod, has prolonged the working life of valve.
Description of drawings
Fig. 1 is a prior art hand stop valve structural drawing;
Fig. 2 is a kind of embodiment structural drawing of the utility model high-performance hand stop valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model high-performance hand stop valve is described in further detail and describes.
Fig. 1 is a prior art hand stop valve structural drawing." door " font structure stand 3 is connected on the valve body 1 by bolt group 2, and oiling cover 6 and copper sheathing 8 are fixed on filler assembly 7 in the support 3, and rotation hand wheel 5 directly is connected with valve rod 4, by the screw thread of support 3 upper ends, drives valve rod 4 and moves up and down.This hand stop valve is simple in structure, but it is big to open and close moment, the switch difficulty, and valve rod 4 is when moving up and down, and valve rod 4 itself also will rotate, and this has just quickened the wearing and tearing of sealing surface and filler, and, valve rod 4 exposes in the part of air more, is easier to be corroded, and can reduce the working life of valve.
Fig. 2 is a kind of embodiment structural drawing of the utility model high-performance hand stop valve.Among the figure, support 3 usefulness bolt groups 2 are connected on the valve body 1.Screw 9 is fixed on pin seat 10 on the support 3, and the pins 11 in the pin seat 10 withstand on one section plane of valve rod 4 corresponding sites and constituted the longitudinal guide that prevents the valve rod rotation, 4 rotations of restriction valve rod.Filler assembly 7 is fixed in the support by oiling cover 6, spring housing 12, and spring 14 withstands filler assembly 7 by spring housing 12, is used for the self compensation of filler.Axle sleeve 13 is enclosed within on the valve rod 4.End face bearing 15 is fixed on support 3 upper ends by gland 16, required moment when being used for reducing rotatable handle 5 and rotating.During rotation hand wheel 5 rotation, by and valve rod 4 between screw thread valve rod 4 is moved up and down, valve rod 4 is subjected to the restriction of pin 11, can not rotation motion, again because the effect of end face bearing 15 is arranged, rotatable handle 5 wants more laborsaving simultaneously.
Design has end face bearing 15 to the utility model high-performance hand stop valve in support 3 upper ends, reduces the difficulty that opens and closes; When opening and closing stop valve, rotate rotatable handle 5, valve rod 4 is subjected to the restriction of longitudinal guide, can not rotation motion.Rotatable handle 5 by and valve rod 4 upper ends between screw thread valve rod 4 is moved up and down.Valve rod 4 can not rotate when moving up and down again, has reduced the wearing and tearing of 4 ends of valve rod, has prolonged the working life of valve.
In addition, as Fig. 1, traditional support is cast the mould complexity, processing inconvenience, and might there be defective in foundry goods, causes support intensity not enough, situations such as fracture occur.In addition, " door " font structure stand 3 is bulky, and profile is not attractive in appearance, and valve rod 4 exposes outside, is threaded again on the valve rod 4 of hand stop valve door, if the working environment of valve is bad, after long-time, to amass full dust on the valve rod 4, it is painstaking to compare in the time of people's operation, and comparatively serious situation then is, valve working is at relatively moister environment, after a period of time, corrosion will appear in valve rod 4, have a strong impact on the usability of valve.
The utility model high-performance hand stop valve; at prior art " door " font structure stand 3; improve on the basis as shown in Figure 1, support 3 stage casings are replaced two original " door " posts with cylinder, valve rod 4 original exposed parts, oiling cover 6 are all protected.
Common stop valve is simple in structure because of having, and cost is low, be easy to make and maintenance, is widely used.But because it is big to open and close moment, the time regular meeting " killing " phenomenon takes place, the switch difficulty, working life is short; Also can cause sealing surface, filler wearing and tearing rapidly, cause the valve evaporating, emitting, dripping or leaking of liquid or gas, waste is serious, influences ordinary production, has increased cost to factory.At the problem that common stop valve exists, the utility model high-performance hand stop valve adopts goes up the totally-enclosed self compensation structure of sealing, and bearing reduces friction, and guide finger is spacing, conical surface metal hard-sealing structure.This valve opening and closing moment is little, and switch is light, and it is little to wear and tear, and sealing is reliable, and the life-span is long, is more than 3 times of common valve.The utility model high-performance hand stop valve is specially adapted on the pipeline of media such as steam, oil, water, hydrogen, methane; Be applicable to the occasion that switch is frequent.
The utility model high-performance hand stop valve is not limited to the scope of embodiment, and all innovation and creation that utilize the utility model design are all at the row of protection.
