Fig. 1 structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of static pressure of water disposal facility and demolition set, comprise boosting cylinder 1, the inner chamber of described boosting cylinder 1 is cylindrical step, comprise first inner chamber 3 in left side and second inner chamber 4 on right side, described first inner chamber 3 and the second inner chamber 4 are interconnected, and the volume of described first inner chamber 3 is greater than the volume of the second inner chamber 4; In the inner chamber of described boosting cylinder 1, piston 2 is set, described piston 2 is I shape, comprise large piston head 10 and valve piston head 11, described large piston head 10 is connected by a long straight-bar with valve piston head 11, described large piston head 10 and the first inner chamber 3 match, and be provided with O-ring seal 14 between described large piston head 10 and the first inner chamber 3, ensure sealing, described valve piston head 11 and the second inner chamber 4 match;
The sidewall of described first inner chamber 3 offers water inlet and water delivering orifice, and described water inlet is near the first inner chamber 3 left side place, and described water delivering orifice is near the first inner chamber 3 right side place; Described water inlet is connected each via the port that water pipe is relative with two of a multiport valve 9 with water delivering orifice, another of described multiport valve 9 is organized relative port and is connected to water inlet pipe 12 and rising pipe 13 respectively, in described multiport valve 9, adjustable catch is set, the adjustable angle of adjustable catch, the flow direction can selecting current after multiport valve 9 by regulating the angle of adjustable catch in multiport valve 9 and coutroi velocity; Described second inner chamber 4 right side place has jet orifice, described jet orifice is connected with water disposal facility 8 to be measured by water pipe, described boosting cylinder 1 is provided with pressure retaining valve 5 and tensimeter 6 with the water route of water disposal facility 8, and described tensimeter 6 is between pressure retaining valve 5 and water disposal facility 8.In addition, there is a moisturizing branch road, described moisturizing branch road one end is connected between pressure retaining valve 5 and the second inner chamber 4, and the other end is connected to water inlet pipe 12, and described moisturizing branch road arranges water compensating valve 7.
Before operation, first the valve piston head 11 in boosting cylinder 1 is moved to the left end of the second inner chamber 4, and be full of water in the first inner chamber 3.When formally starting to test, open pressure retaining valve 5, close water compensating valve 7, have tap water endlessly to flow in water inlet pipe 12, rotate the adjustable catch of multiport valve 9, make the water pipe that the opening of adjustable catch is connected towards left side with water inlet, water then flows into the first inner chamber 3 from water inlet, and large piston head 10 and the first inner chamber 3 closely cooperate and have O-ring seal 14 to seal, and water jet propulsion piston 2 moves from left to right, water in first inner chamber 3 is clamp-oned in the second inner chamber 4, and then flows in water disposal facility 8 to be measured.Because of the small volume of the second inner chamber 4, therefore hydraulic pressure rises, and by slowly adjusting the opening angle of adjustable catch, controls the speed of boosting until reach the force value of setting.Now, close pressure retaining valve 5, in boosting cylinder 1, unnecessary water flows out and flows away from rising pipe through multiport valve 9 from water delivering orifice, when the pressure of force value needed for tolerance static pressure of setting, when being generally 2MPa, observe water disposal facility 8 under this hydraulic pressure and, with or without drainage, if without leaking, then prove that water disposal facility 8 tolerates static pressure test qualified; Otherwise, if leak, then defective; When the force value of setting is burst pressure, when being generally 3.5MPa, in boost process, observe water disposal facility whether before this set pressure, just explosion occurs, if explosion before set pressure, then burst pressure test failure, if reach the burst pressure of setting, water disposal facility just explosion or still do not have explosion, then burst pressure test passes.In the process of closing pressure retaining valve 5, the pressure that tensimeter 6 shows if find when declining to some extent, is then opened water compensating valve 7 and pressure retaining valve 5, is increased the injection of water, and then closes water compensating valve 7 and pressure retaining valve 5 again after reaching set pressure.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
