Abstract
The utility model relates to a novel throttle valve which comprises a top entry stuffing structure, a soldered valve rod component and a soldered valve seat component; wherein the top entry stuffing structure is a structure that the cavity of the stuffing box is opposite to the medium in the valve body; the soldered valve rod component is formed by connecting the valve rod body with a valve rod head made of special corrosion and wear resistant material in a soldering way; the soldered valve seat component is formed by connecting the valve seat body with a valve seat bushing made of special corrosion and wear resistant material in a soldering way. By adopting the technical scheme, the problems that the replacement of stuffing is troublesome, the valve rod and the valve seat which are made of ordinary materials are easy to wear out and fail, and special corrosion and wear resistant integrated valve rod and valve seat require high cost which are caused by adopting the prior structure can be solved.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of adjustable throttle valve of novel aciculiform that is used to regulate fluid flow.
Background technique
The adjustable throttle valve of aciculiform is applicable to from oil spout (gas) well, for adopting regulated fluid flow usefulness in defeated and the production process.Throttle valve as shown in Figure 1 rotates adjustable throttle valve handwheel, drives the valve rod generation and moves axially, and the circular cone gap of valve rod needle point position and valve seat is changed, and reaches the purpose of regulating flow.
Though above-mentioned throttle valve is widely used, also there are some defectives in actual application, tracing it to its cause mainly is: 1, owing to stuffing box cavity hatch medium one side in valve body, it is cumbersome to change stem packing; 2, owing to the high-voltage high-speed fluid scouring, the valve rod head washes away distortion easily and scraps; 3, adopt integrated type valve rod, valve seat cost too high.
Summary of the invention
Goal of the invention of the present utility model is exactly in order to overcome above-mentioned deficiency, provides a kind of convenient and valve rod head of filler of changing to be difficult for washing away the novel throttling valve of distortion.
The technical solution of the utility model is as follows:
A kind of novel throttling valve, comprise valve body, stuffing box, the valve rod that is provided with in the valve cavity, the handwheel that the valve rod front end is provided with, the valve seat of the cooperation valve rod that the valve cavity rear portion is provided with, wherein said stuffing box are the last dress formula stuffing box of medium in the valve body, the soldering valve rod assembly of described valve rod for valve stem body and stem head being connected as a single entity by brazing mode, the soldering valve component of described valve seat for valve seat body and valve seat lining being connected as a single entity by brazing mode.
The utility model working procedure is: after medium enters the throttle valve cavity, last dress formula stuffing box and valve body, valve rod form the sealing to medium, by the rotary barrel throttle handwheel, driving the valve rod generation moves axially, the circular cone gap of valve rod needle point position and valve seat is changed, thereby regulate rate-of flow.
The utility model compared with prior art has following advantage:
1, go up the design of dress formula filler because the utility model adopts, the filler assembly and disassembly are more easy to operate, when the maintenance throttle valve, are convenient for changing filler, save the maintenance maintenance time.
2, because the utility model adopt to be gone up the design of dress formula filler, behind the filler failure damage in the stuffing box, its remains are difficult for sneaking into medium in the valve pocket, avoid blocking restriction and pipeline miscellaneous equipment and the potential safety hazard that causes.
3, because the utility model adopts the anti-special corrosion resisting of soldering and high-abrasive material valve rod, valve component, can reduce medium and wash away destruction valve rod, valve seat, prolong its working life.
4, the compare anti-special corrosion resisting of integrated type and high-abrasive material valve rod, valve seat of the anti-special corrosion resisting of soldering that adopts of the utility model and high-abrasive material valve rod, valve component saved cost significantly, is beneficial to batch process.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is an adjustable throttle valve structural drawing in the prior art.
Fig. 2 is the utility model structural drawing;
Wherein: 1, valve body, 2, valve rod, 3, valve seat, 4, stuffing box, 5, handwheel, 6, the filler sand frame, 7, O RunddichtringO, 8, Gland, 9, the O RunddichtringO, 10, seal ring, 11, the O RunddichtringO, 12, the hole back-up ring, 13, valve stem body, 14, stem head, 15, the valve seat body, 16, the valve seat lining.
Embodiment
For the ease of the utility model is further understood, make technological means, creation characteristic that the utility model realizes, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Present embodiment as shown in Figure 2, comprise valve body 1, stuffing box 4, the valve rod 2 that is provided with in the valve cavity, the handwheel 5 that the valve rod front end is provided with, the valve seat 3 of the cooperation valve rod that the valve cavity rear portion is provided with, wherein said stuffing box is the last dress formula stuffing box of medium in the valve body, the soldering valve rod assembly of described valve rod for valve stem body 13 and stem head 14 being connected as a single entity by brazing mode, the soldering valve component of described valve seat for valve seat body 15 and valve seat lining 16 being connected as a single entity by brazing mode.
The described structure that goes up stuffing box cavity that dress formula filling-material structure is made up of with back-up ring 12 Stuffing box 6, O RunddichtringO 7, Gland 8, O RunddichtringO 9, seal ring 10, O RunddichtringO 11 and hole medium in the valve body.During installation, put into seal ring 10 back and are screwed into Gland 8 and compress in Stuffing box 6, again the circlip groove of Stuffing box 6 is put into back-up ring 12 in the hole, step is opposite during dismounting.
Stem head in the described soldering valve rod assembly is anti-special corrosion resisting and high-abrasive material, select suitable solder and brazing flux for use, under specific process conditions, make valve stem body and stem head strong bonded, after soldering finishes, intensity to whole soldering valve rod assembly detects, and guarantees not come off under medium washes away.
Valve lever bushing in the described soldering valve component is anti-special corrosion resisting and high-abrasive material, select suitable solder and brazing flux for use, under specific process conditions, make valve seat body and valve seat lining strong bonded, after soldering finishes, intensity to whole soldering valve component detects, and guarantees not separate under medium washes away.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
