Abstract
The utility model provides a valve with a regulating and locking mechanism. The valve is composed of a valve body and a valve rod. A regulating wheel and a regulating valve are arranged on the valve body, the regulating wheel can regulate the flow of the valve, the regulating valve is matched with the outer circle of the valve body, and the regulating wheel is connected with the regulating valve in a rectangular or square thread manner; the valve rod is matched with the valve body by the regulating valve and the regulating wheel, and the positions of the regulating valve and the regulating wheel can be locked by a locking rod; a sealing sleeve is arranged above the regulating wheel along the shaft line and is matched with the valve rod; a pressing cap is arranged above the regulating valve and is used for pressing and protecting the valve rod as well as the locking rod, operation openings are opened at the two edges above the regulating valve along the direction of the shaft line, so as to be convenient for replacing spare sealing pieces. The valve has the characteristics that: the valve endures abrasion and cannot be easily damaged; the service life of the valve is three to five times longer than that of the common valve; the turning on/off is convenient and the sealing property is good; the valve can easily control the flow, saves water or oil and saves raw materials as well.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of valve of regulating locking framework that has of can regulate flow.
Background technique
The valve of Chu Xianing is mostly for there is a valve body outside in the market, and there is a valve rod that has plug the centre, is processed with fine thread on the valve rod and matches with valve body, when rotating valve body, opens or throttle down, promptly realizes the use of water or other liquid.The shortcoming of this valve is: 1) its screw thread is arranged on the valve rod, when opening valve, because fluid has certain pressure can be dipped into helical thread portion on the valve rod, valve rod or screw thread is got rusty, and influences its working life; What 2) its helical thread portion used is fine thread, and under frequent situation of opening, easy to wear or slide fastener damages easily; 3) owing to can arbitrarily open or close valve, its flow can change with the variation of fluid pressure, so flow can't be fixed.The shortcoming of above-mentioned valve makes that the working life of valve is very short, can only keep about 1 year and will damage.Because valve is a kind of damageable spare parts, its employed raw material mostly is a copper product, and cost price is higher, and therefore, it is a kind of very big waste that a large amount of valves damages material, has also increased the number of times and the trouble of frequent replacing valve.
The model utility content
The purpose of this utility model is the improvement of carrying out at the deficiency of above-mentioned valve technology.The utility model proposes a kind of novel valve that has adjusting and locking framework of can regulate flow.This valve is designed into the excircle part of regulating wheel with the internal thread drive part on the former valve rod, and it is cooperated with the rectangle or the flat thread of modulating valve by large screw pitch, the screw strength when increasing its rotation; Helical thread portion is moved outward, and stop or reduce the etch of liquid valve rod by sealed member.Owing to be provided with locking framework, can adjust its flow easily and, do not having under the situation of instrument its locking position, be not easy valve is arbitrarily rotated and changes its flow.
Technical solution of the present utility model is as follows: have the valve of regulating locking framework and be made up of valve body and valve rod, be characterized on valve body, being equipped with the regulating wheel of adjustable gate flow and the modulating valve that matches with its cylindrical, valve rod cooperates with valve body by modulating valve and regulating wheel, and locking lever inserts the locking position that will adjust flow in modulating valve and the regulating wheel; Wherein: regulating wheel is that rectangle or flat thread are connected with modulating valve, stuffing box gland is installed above regulating wheel and matches with valve rod, and stuffing box packing or seal ring are housed below stuffing box gland; Exterior top at modulating valve is provided with gland, in order to push down and to protect valve rod and locking lever; Two edge axial directions have two gathering holes down to the position of stuffing box gland above the modulating valve outside, with dismounting and the replacing that makes things convenient for stuffing box gland.
The utility model switch is convenient, and good airproof performance is wear-resistant, not fragile, and its life-span is three to five times of at present general valve; Easy control flow rate, using water wisely or with oil, the while also saves material.
Description of drawings
Followingly with reference to accompanying drawing the utility model is carried out more detailed structure and describe in detail.
Fig. 1 is a package assembly schematic representation of the present utility model
Fig. 2 is a left view of the present utility model
Fig. 3 is that A of the present utility model is to view
Embodiment
With reference to Fig. 1, the utility model is made up of valve body in the prior art 7 and the valve rod 2 that has plug, and its structure is identical with prior art.Outstanding improvement of the present utility model is the regulating wheel 4 that the adjustable gate flow has been installed on valve body 7, be processed with the square threaded form of large screw pitch on its cylindrical, be processed with the square threaded form internal thread of large screw pitch on the interior circle of modulating valve 1 with matching, valve rod 2 passes modulating valve 1 and cooperates with valve body 7 by regulating wheel 4, the liquid entrance place of its plug in valve body 7 moves up and down, when moving down, and throttle down, when moving up, open valve; Moving up and down by rotating modulating valve 1 of valve rod 2 makes it realize with regulating wheel 4 relative moving up and down.Stuffing box gland 3 has been installed above regulating wheel 4, stuffing box packing or seal ring has been housed below the stuffing box gland 3, itself and valve rod 2 are slidingly matched and liquid seal are lived, and liquid is not upwards overflowed.Rotate modulating valve 1 its relative adjustment wheel 4 is moved, and drive valve rod 2 and move up and down, after the size of its flow is determined, locking lever 5 is inserted the locking position that will adjust flow in modulating valve 1 and the regulating wheel 4; The outer tip end of modulating valve 1 is provided with gland 6, pushes down and protect valve rod 2 and locking lever 5 arbitrarily not to be rotated with gland 6.Two edge axial directions above modulating valve 1 have two gathering holes down to the position of stuffing box gland 3, the stuffing box gland 3 in the middle of can tightening with spanner easily or unclamp, the also easily dismounting and the replacing of stuffing box gland or stuffing box packing.
Advantage of the present utility model and effect are: adopted the outside thread of large screw pitch, made on the valve rod not to be threaded, reduced matching gap and to the etch of valve rod, good airproof performance cooperates intensity to increase, and screw thread is not easy to wear, be difficult for getting rusty, the life-span of valve can be used three to five years.Owing to adopted position locking mechanism, can easily liquid be fixed on a suitable flow, just open with what much, but using water wisely.
The utility model can be widely used in the transportation pipeline of water, oil or gas.
