Abstract
The utility model relates to an elasticity sealed ball valve. A sealing ring seat is positioned in a connecting sleeve which can be disassembled, an adjusting ring is arranged on the sealing ring seat, and a group of adjusting bolts are arranged on the connecting sleeve. Pressure springs are arranged between the sealing ring seat and the adjusting ring, and a sealing ring is arranged at the inner end of the sealing ring seat. The adjustments of the adjusting bolts can change the position of the adjusting ring to control the pressing forces of the sealing ring seat, and the pressing forces are made by the pressure springs. The utility model can be widely used for metallurgy industry, chemical industry, cement industry, food industry, etc. and has the advantages of good sealing performance, and conveniences for using and repairing.
Description
The utility model relates to a kind of ball valve.
Ball valve is industrial stopper commonly used, the sealing mechanism of ball valve has very big influence to its usability, existing Unloading ball valve all adopts elastic sealing structure, seal ring is contained in non-dismounting one side of valve body, change inconvenience when seal ring damages so on the one hand, can not adjust the impacting force of sealing surface according to the character of medium on the other hand, after the wearing and tearing of seal ring, can not do compensation adjustment again.Disclosed a kind of elastic packing ball valve among the CN88203492.8 is located at the dismounting end of valve body with elastic packing mechanism, but still lacks the adjustability of seal ring impacting force, causes its usability poor.
The purpose of this utility model is to disclose a kind of ball valve with adjustable sealing mechanism.
Task of the present utility model is achieved in that packing holder is located in the releasable connection cover, with this connecting sleeve for movingly, can endwisely slip, be provided with stage clip between sealing ring support outer end and the adpting flange, adjust the connecting sleeve position of encircling the outer end and be provided with the adjusting bolt.
Do not establish in the prior art and adjust ring and regulate bolt, stage clip adds and is located between seal ring and the packing holder, or add and be located between packing holder and the connecting sleeve, though can form elastic packing, but impacting force can not be by medium and operating conditions adjustment, impacting force descends gradually after the ring wear, can't compensate.The sealing mechanism that adopts the utility model to provide is regulated bolt by rotation, can change the impacting force of sealing surface, adapting to different medium, different operating condition, or the wearing and tearing of seal ring is compensated.This ball valve opens and closes flexibly, and good airproof performance uses easy to maintenancely, can be widely used in industries such as metallurgy, chemical industry, cement, food.
With regard to drawings and Examples the utility model is specified below.
Fig. 1 is the utility model structural representation.
Actuator 1, valve body 2, spheroid 3, releasable connection cover 4 are ball valve basic structure among the figure, and packing holder 5 is located at the inside of connecting sleeve 4, connects movingly, and packing holder 5 can be moved axially.Interior end slot the inner of packing holder 5 is provided with seal ring 6, forms sealing with spheroid 3.Be provided with between the outer end of packing holder 5 and the connecting sleeve 4 and adjust ring 7, connecting sleeve 4 is provided with regulates bolt 8, adjusts between ring 7 and the packing holder 5 and is provided with stage clip 9.
Stage clip 9 can adopt dual mode: for small-bore ball valve, can use the heavy caliber stage clip, the stage clip diameter is consistent with the pressure spring slot diameter of packing holder 5, for the heavy caliber ball valve, can use one group of small-bore stage clip, is distributed on to adjust between ring 7 and the packing holder 5.
Between packing holder 5 outer walls and connecting sleeve 4, also can add seal ring 10, prevent that medium from leaking from matching part.
According to working medium character, adjust the adjusting bolt 8 on the connecting sleeve 4 during use, change the position of adjusting ring 7, thus the impacting force of 9 pairs of packing holders 5 of control stage clip.After seal ring 6 wearing and tearing, above-mentioned adjustment can be used as the compensation adjustment means of impacting force, and the sealing effect of ball valve can not descended, and whole sealing mechanism is located on the releasable connection cover 4, and processing, assembling and maintenance are also brought convenience.
Claims (4)
1, a kind of elastic packing ball valve comprises actuator, valve body, and spheroid, releasable connection cover and sealing mechanism is characterized in that:
A packing holder 5 overlaps 4 inwalls with releasable connection and is connected movingly,
Adjust ring 7 for one, be located between packing holder 5 outer ends and the connecting sleeve 4,
Regulate bolt 8 for one group and be located at and adjust on the ring 7 pairing connecting sleeves,
Between adjustment ring 7 and packing holder 5, be provided with stage clip 9, be provided with seal ring 6 in the interior end slot of packing holder 5.
2, by the described elastic packing ball valve of claim 1, it is characterized in that described stage clip 9 is a major diameter spring.
3, by the described elastic packing ball valve of claim 1, it is characterized in that described stage clip 9 is one group of uniform minor diameter spring.
