Description
Technical field
The utility model relates to a kind of valve technology field, the pneumatic angle pedestal valve that relates in particular to a kind of bidirectional open and close, and have high circulation capability, be applicable to that mainly all kinds of steam pipeline engineering systems are done to connect and cut-off valve is used.
Background technique
The straight-through form of the stop valve of Sheng Chaning is more in the market, but has following shortcoming: the one, and poor streamline, local resistance is big, and negotiability is poor, and this energy loss to pipe-line system is big, and the loss that therefore how to reduce resistance also is a very important problem.A manufactory often proof strength and sealability is qualified, and payes attention to not enough to the flow resistance that reduces valve.The 2nd, when stop valve was flowed through valve seat usually from top to bottom, its shortcoming was that the medium active force all acts on the valve rod when closing, the incompatibility high pressure.The valve seat so flow through from the top usually during high pressure is closed moment with minimizing.When flowing into from the below, because the washing away of fluid, flap damages earlier easily, and when flowing into from the top, fluid washes away comparison severity to valve seat, so valve seat damage earlier easily.The 3rd, filler after using after a while filler compress bad accent once more after, need pull down some parts of cylinder, by compressing once more of attaching nut, could realize that the compensation of filler compresses.The 4th, the flap seal ring was to compress by nut and pad, after using a period of time in the past, rubber has certain wearing out, and elasticity reduces, and easily nut is dashed pine when fluid scouring, even come off, will cause dropping out of seal ring like this, do not have the effect of closing sealing.The 5th, the most metal partss that adopt of cylinder are in the past made.One cost height, its two frictional force is big, thereby has also reduced pneumatic valid function power.
The model utility content
The purpose of this utility model provides a kind of bidirectional flow pneumatic angle pedestal valve, this bidirectional flow pneumatic angle pedestal valve has not only reduced the flow resistance of valve, improve the negotiability of valve, also strengthened the working life of filler and seal ring, and reduced the cost of whole pneumatic angle pedestal valve.
In order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: a kind of bidirectional flow pneumatic angle pedestal valve, comprise valve body, the screw channel of described valve body is provided with valve rod, described valve rod lower end is provided with seal, be installed on the valve body, be provided with seal ring in the groove of described seal, described seal ring lower side is provided with packing ring, and described valve body upper end is provided with valve gap, passes through scyewed joint, described valve gap adopts by the dish spring with cylinder block and is threaded, and gland nut locking is arranged, be provided with filler and following filler in the described valve gap body, and between last filler and following filler, be provided with counterbalance spring, described cylinder block is installed on the upper end of valve rod, be provided with piston in the described cylinder block, and on valve rod, be provided with piston packing in the groove of described piston, described cylinder block upper end is provided with cylinder head, by being threaded.
Be provided with Returnning spring between described cylinder head and the piston.
Be provided with sealing gasket between described valve body and the valve gap.
Owing to be provided with said structure, this bidirectional flow pneumatic angle pedestal valve is simple in structure, and moulding is easy, and is in light weight, easy to maintenance, and cost is lower.
Description of drawings
Fig. 1 is the structure sectional view of a kind of bidirectional flow pneumatic angle pedestal valve of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, a kind of bidirectional flow pneumatic angle pedestal valve, comprise valve body 1, the screw channel of described valve body 1 is provided with valve rod 5, described adjustable valve rod 5 lower ends are provided with seal 4, be installed on the valve body 1, be provided with seal ring 3 in the groove of described seal 1, described seal ring 3 lower sides are provided with packing ring 2, described valve body 1 upper end is provided with valve gap 6, and by scyewed joint, described valve gap 6 adopts by dish spring 10 with cylinder block 13 and is threaded, and there is gland nut 12 to lock, assurance can not get loose because of vibration, is provided with filler 8 and following filler 81 in described valve gap 6 bodies, and is provided with counterbalance spring 9 between last filler 8 and following filler 81, the impacting force of counterbalance spring 9 is that pressured jack panel 12 and dish spring 10 are controlled, when filler after using wearing and tearing after a while, the power of counterbalance spring 9 still can compress filler, keeps the effect of sealing.Described cylinder block 13 is installed on the upper end of adjustable valve rod 5, is provided with piston 15 in the described cylinder block 13, and on valve rod 5, is provided with piston packing 14 in the groove of described piston 15, and described cylinder block 13 upper ends are provided with cylinder head 17, by being threaded.Be provided with Returnning spring 16 between described cylinder head 17 and the piston 15.Under the normal condition, the pressure of Returnning spring 16 promotes piston 15 and valve rod 5 moves downward, and drives seal 4 and seal ring 3, makes it close inlet passage.When employing is flowed from top to bottom, need to adopt bigger Returnning spring 16 power, just can make valve closing.When flowing from top to bottom, closing of valve is by medium power and spring force, so sealing is reliable, is to lean on the active force of piston 15 to make valve open when opening.No matter upper reaches or upward dirty because the area of valve seat mouth and the area of aditus laryngis equal drift diameter area, adds that streamline is similar to straight line under being, so this valve flow resistance is little, negotiability is big.Be provided with seal ring 3 between described valve body 1 and the valve gap 6.
It should be noted that at last: above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to the technical solution of the utility model and replace, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
