Description
Technical field
The utility model is related to coal gas valve chest air-leakage test technology, specifically discloses a kind of coal gas valve chest and leaks hunting dress
Put.
Background technology
The leak-checking apparatus that many producers use are as shown in figure 1, including support frame, supporting plate, lower air cylinder, fixture stand, folder
Tool, silica gel fixed plate and air inlet pipe, supporting plate are set up on support frame, and lower air cylinder is fixed in supporting plate；Fixture stand is set
In support frame inner side, fixture is located at fixture stand top；Two products are formed in chucking surface fix station, silica gel fixed plate
(soft texture is fitted even closer with product) is arranged at product and chucking surface contact position；Die pressing product under lower air cylinder, makes
Obtain and fitted between product and fixture closely；One air inlet pipe forms two branch roads, is penetrated from fixture lower section respectively, is led with product cavity
It is logical；Air pressure regulator is respectively provided with every branch road；The gas injection in housing, sets pressure peak and testing time, air pressure
Kept after stabilization, step-down interval is set, then automatic detection；Product part gas leakage, Ran Houtong are illustrated if step-down value is bigger than normal
It is specifically certain part to cross the observation of surface smear expanding foam solution；Such detection method trouble, efficiency is low, a machine of people one, disposably
Complete two detections of product, it is impossible to intuitive judgment air leak position, smearing expanding foam solution observation air leak position is comparatively laborious, and foaming
Liquid has corrosiveness, unfavorable to people, product, not easy cleaning after expanding foam solution is dry, influences product quality.
Utility model content
Goal of the invention of the present utility model is：A kind of simple structure is provided to solve problem above, it is easy to operate, leak hunting
Effect is good, efficiency high, can be accurately positioned the coal gas valve chest leak-checking apparatus of air leak position.
The technical scheme that the utility model is used is such：
Coal gas valve chest leak-checking apparatus, including support frame, supporting plate, lower air cylinder, fixture, silica gel fixed plate and air inlet pipe
Road, wherein the fixture is hung on supporting plate lower section；Also include hoisting frame and lifting cylinder, the hoisting frame is arranged at the branch
Support inner side, lifting cylinder effect motion upwards that can be with respect to support frame as described above by being arranged above the supporting plate；Described
Hoisting frame correspondence fixture lower section forms water storage container, and the upward motion of hoisting frame can ensure that product submerges in water completely.
Further, at least one product is formed on the fixture and fixes station.
Further, the admission line can be conducted to product cavity from the entrance of fixture top.
In sum, due to using the above-mentioned technical proposal, the beneficial effects of the utility model to be：
The utility model is inflated in product cavity, and gas leakage situation is observed in the water that then submerges, very clear judgement product
Air leak position, simple to operate, effect of leaking hunting is good, efficiency high；The people of such structure one can complete many operations of machine, once complete
Leaking hunting for multiple products, saves manpower, improves detection efficiency.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Fig. 2 coal gas valve chest leak-checking apparatus, including support frame 1, supporting plate 2, lower air cylinder 3, fixture 4, silica gel
Fixed plate 5 and admission line 6, wherein the fixture 4 is hung on the lower section of supporting plate 2, two products is formed on fixture 4 and are fixed
Station；The admission line 6 can be conducted to the inner chamber of product 10 from the entrance of the top of fixture 4.
Also include hoisting frame 7 and lifting cylinder 8, the hoisting frame 7 be arranged at the inner side of support frame as described above 1, can be relatively described
Support frame 1 acts on motion upwards by the lifting cylinder 7 for being arranged at the top of the supporting plate 2；In the correspondence fixture 4 of the hoisting frame 7
Lower section forms water storage container 9, and the upward motion of hoisting frame 7 can ensure that product 10 submerges in water completely.
Housing back-off is started into lower air cylinder 3 on fixture 4 during operation, it is ensured that fitted between housing and fixture 4 closely, shell
Intracoelomic cavity is inflated and keeps lasting air inlet, starts lifting cylinder 8, and lifting cylinder 8 drives hoisting frame 7, is further driven to lower section and is stored
Water receptacle 9 rises, until product 10 submerges completely in water；The abnormal bubble situation of observation (is not excluded for partial air from housing and folder
Run out of between tool 4), it is accurate to judge housing air-tightness；Test is completed, and closes air inlet, and lifting cylinder 8 resets, and lifting bracket 7 goes downwards to
Position；Lower air cylinder 3 resets, and takes out product.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
