Abstract
A water pressure sealing testing device of a fire hydrant comprises a sealing tank body and a pressure meter arranged on the tank body. The tank body is composed of an upper portion and a lower portion. An upper-portion end socket and a lower-portion tank body are connected through pressing cover flanges welded onto the upper-portion end socket and the lower-portion tank body respectively, and an O-shaped sealing ring is arranged between the pressing cover flanges. A liquid gas storage tank is modified into a pressure container, the assembled fire hydrant is put into water in the container, pressure is delivered to a water surface through air pressure, and whether the fire hydrant leaks is checked through water pressure. The water pressure sealing testing device is simple in structure and convenient and reliable to use.
Description
Technical field
The utility model relates to a kind of hose saddle hydraulic sealing test device.
Background technology
Hose saddle requires outside inner sealing to be prevented sewage to the corrosion of inner operation part, require the hose saddle installation after, from the outside to inner water whole hose saddle is filled, suppress 0.3Mpa with hydraulic pressure.Pressurize 2 hours is seen hose saddle inside has or not to leak.Thisly suppress the mode more complicated, and effect neither be fine.
The utility model content
The utility model technical issues that need to address provide a kind of air pressure transmission of pressure that utilizes, the hose saddle hydraulic sealing test device whether the test hose saddle leaks.
For addressing the above problem, technical solution adopted in the utility model is: a kind of hose saddle hydraulic sealing test device, comprise sealed shell of tank and be installed in tensimeter on the tank body, described tank body is comprised of two parts up and down, the top end socket is connected to be welded on respectively the top end socket is connected gland flange and connects with the bottom tank body with the bottom tank body, be provided with the O RunddichtringO between the gland flange.
The inside of this novel bottom tank body is provided with base plate, and the base plate periphery welds together with inner tank wall.
The bottom of described tank body also is provided with supporting leg, and number of legs is 3, triangular in shape being welded on the tank body.
Whether the beneficial effect that adopts technique scheme to produce is: this is novel repacks pressure vessel into liquid gas storage tank, and the hose saddle that assembles is put in wherein the water, utilizes the air pressure transmission of pressure to the water surface, leak with hydraulic pressure inspection hose saddle.Simple in structure, easy to use and reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, supporting leg, 2, base plate, 3, gland flange, 4, the O RunddichtringO.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail: as shown in Figure 1, the utility model is a pressure vessel with the liquid gas storage tank repacking, formed by two parts up and down, top end socket and bottom tank body weld respectively gland flange 3, the top end socket is connected gland flange and connects sealing with the bottom tank body, be provided with O RunddichtringO 4 between the gland flange, and is convenient in order to pick and place hose saddle, inside at the bottom tank body is provided with base plate, and the base plate periphery welds together with inner tank wall; The bottom of tank body also is provided with supporting leg 1, and number of legs is 3, triangular in shape being welded on the tank body.
Principle of work:
Open gland flange, with putting into water in the container, mounted hose saddle is put into container first, the rim of the mouth that O type circle blocks gland flange is put the top end socket and is built, and with fit sealing, air intake opening is adjusted to 0.3Mpa with reduction valve with pressure with 8 bolts.Close air intake valve.Keeping the 2H pressure drop is qualified less than 0.001Mpa, need reprocess hose saddle greater than 0.01Mpa, checks the place that leaks of hose saddle.
This product utilization air pressure transmission of pressure checks with hydraulic pressure whether hose saddle leaks to the water surface.Simple in structure, easy to use and reliable.
