Description

A kind of balanced valve of energy bidirectional pressure regulating

Technical field

The present invention relates to space industry, the aviation flight having higher requirements in particular with volume, q&r Device.

Background technology

Balanced valve general at present is only capable of operating in unilateral side, in the case where external and internal pressure changes, one-way operation balance Valve has certain limitation, although this can be solved the problems, such as by anti-dress one-way balance valve in parallel, can additionally increase in this way Volume and quality.

Aviation aircraft has tighter requirement for the volume of valve, q&r, in order to meet this requirement, Need the balanced valve of energy bidirectional modulation.

Invention content

For the defects in the prior art, the object of the present invention is to provide a kind of balanced valve of energy bidirectional pressure regulating, overcome often The deficiency for advising balanced valve, meets the demand of the aviation aircraft balanced valve high to small, light weight, reliability.

In order to achieve the above object, the technical solution adopted in the present invention is as follows:

A kind of balanced valve of energy bidirectional pressure regulating, including:The interior operating device that is mainly made of rotation hand wheel and hand wheel pole, master Will by outer operating device that sleeve and chapiter screw form, the valve body being mainly made of undersetting and plunger, mainly by spring, valve The valve core component of core composition, chapiter screw pass through the centre bore of sleeve and undersetting, spring to be inserted in chapiter screw, spool It being installed on chapiter screw top and screws, hand wheel pole passes through plunger and screws in certain number of teeth, and hand wheel pole and plunger are inserted into undersetting, Undersetting and plunger are fixed by cap nut;Hand wheel pole one end is installed by rotation hand wheel;When internal pressure regulation, hand is rotated by rotation Wheel and hand wheel pole, open-top spool so that spool is detached with plunger, realizes the connection of inside and outside gas circuit;When external pressure regulation, pass through rotation Sleeve drives fillister head screw and spool movement so that spool is detached with plunger, realizes inside and outside gas circuit connection.

Undersetting and plunger realize double containment by sealing ring.

Sealing ring is cased between spool and plunger, when hand wheel pole or sleeve return, spool return under the action of the spring, Spool is withstood on plunger, and sealing is realized by compressing sealing ring.

It is that line contacts between sleeve and chapiter screw, when turnbarrel is displaced outwardly, to ensure that chapiter screw only makees line Shape moves, without rotary motion, it is ensured that spool can be opened.

Thread pitch between chapiter screw and spool applies anaerobic adhesive, when ensuring chapiter screw movement, spool and its One movement.

The pressure that balanced valve can be born depends on the stiffness coefficient of spring.

Several ventholes are offered in the circumferential direction of plunger, spool and sleeve, so that inside and outside balanced valve is fully connected to.

In addition to sealing element, balanced valve is that metal material is made.

Compared with prior art, the present invention has following advantageous effect:

1) operating device is respectively placed in spool both sides inside and outside, and operation is independent, and reliability is high;

2) spool and two sets of operating devices are integrated in a valve, have compact-sized, volume and quality small;

3) the closed power of spool is determined by the stiffness coefficient of spring, can select suitable spring, applicable surface according to actual needs Extensively;

4) valve is metal assembly in addition to sealing element, manufactures simple processing, and intensity and reliability are high.

Description of the drawings

Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention, Objects and advantages will become more apparent upon:

Fig. 1 is the cross-sectional view of balanced valve of the present invention;

Fig. 2 is Bidirectional balanced valve connected state air-flow schematic diagram;

Fig. 3 is the circumferential venthole of plunger;

Fig. 4 is the circumferential venthole of sleeve.

Specific implementation mode

With reference to specific embodiment, the present invention is described in detail.Following embodiment will be helpful to the technology of this field Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.These belong to the present invention Protection domain.

It is provided by the invention it is a kind of can bidirectional modulation balanced valve, in spool, both ends are equipped with operating device end to end, make Obtaining spool can be turned on or off in both sides, realize bidirectional operation;The operating device of spool and end to end both sides is integrated in one In valve body, the volume and quality of Bidirectional balanced valve are reduced, for valve in addition to sealing O-ring, remaining is metalwork, is improved The reliability of valve.

Shown in Fig. 1, bidirectional modulation balanced valve provided by the invention, including undersetting 1, sleeve 2, O-ring 3, interior hexagonal circle Chapiter screw 4, spring 5, spool 6, the first O-ring 7, the second O-ring 8, cap nut 9, hand wheel pole 10, plunger 11, rotation hand Wheel 12, washer 13, nut 14 form.Nut 14, washer 13, rotation hand wheel 12 and hand wheel pole 10 form interior operating device;Sleeve 2 Outer operating device is formed with chapiter screw 4;Undersetting 1 and plunger 11 form valve body, are fixed by cap nut 9, undersetting 1 and column Double containment is realized by the first O-ring 7 between plug 11;Spring 5, spool 6 and the second O-ring 8 form valve core component, realize valve The opening and closing of door.

Shown in Fig. 2, when valve is opened from inside, by rotating rotation hand wheel 12 and hand wheel pole 10, open-top spool 6 so that Spool 6 is detached with plunger 11, and inside and outside air cavity is connected to, and voltage regulation result is reached;When valve is opened from outside, pulled using interior hexagonal Hand turnbarrel 2 drives chapiter screw 4 and 6 linear movement of spool so that spool 6 is detached with plunger 11, realizes that inside and outside air cavity connects It is logical, reach voltage regulation result.

Outside Bidirectional balanced valve divided by upper seal, remaining is all-metal construction.

Chapiter screw 4 passes through sleeve 2, passes through the centre bore of undersetting 1, spring 5 is inserted in chapiter screw 4, spool is pacified Loaded on chapiter screw top, and screw;Hand wheel pole 10 is passed through into plunger 11, and screws in certain number of teeth, by hand wheel pole 10 and plunger 11 are inserted into undersetting 1, put on cap nut 9;Rotation hand wheel 12, washer 13 and nut 14 are loaded onto successively in 10 taper end of hand wheel pole.

Shown in Fig. 3, Fig. 4, in order to make inside and outside balanced valve is fully connected to, if the circumferential direction in plunger, spool and sleeve offers Dry venthole 15, wherein Fig. 4 left ends be through-hole, right end for ease of operation interior hexagonal structure.

So far, Bidirectional balanced valve assembly is completed.
