In the utility model, the structure is simple, the operation is convenient, the wearing degree is low, the usage life is long, and the test is visual and reliable.
Description
Technical field
The utility model relates to the proving installation technical field of the foundry goods of Foundry Production, and is special relevant with the valve plate pressure testing machine.
Background technology
At the foundry goods (coloured) of Foundry Production, all be screw rod fastener pressure testing with 20m/m, this is simple to operate; And long-term the use, screw rod is logical during operation wears valve plate, and two is with rubber of arc piece pad; Fastening nut needs two people to operate and can accomplish again, and this structure is because of nut compressing; Rubber on the arc piece is often damaged, has influenced working efficiency and manufacturing schedule.
In order to address the above problem, the inventor designs the valve plate pressure testing machine, and this case produces thus.
The utility model content
The purpose of the utility model provides a kind of valve plate pressure testing machine, and simple in structure, easy to operate, the degree of wear is little, long service life.
In order to achieve the above object, the utility model is realized through following technical scheme:
The valve plate pressure testing machine comprises the water tank that is used for splendid attire water, at an end of water tank the air inlet jacking block is installed, and the other end is cylinder fixedly, and the piston rod of cylinder stretches in the water tank, cooperates with the air inlet jacking block to grasp valve plate to be checked; The external source of the gas of air inlet socket is installed on the water tank, leads to the air inlet jacking block, give valve plate inflation to be checked, gas admittance valve and air outlet valve are installed on the gas circuit through gas circuit.
Described water tank bottom is provided with the cushion block of support valve plate to be checked.
Establish in the described gas circuit on the inwall with water tank.
Described cylinder piston boom end is equipped with the cylinder jacking block.
Described water tank bottom is equipped with deflecting roller.
Described tank outer wall connects the handle that is used to promote water tank.
After adopting such scheme, the utlity model has many beneficial effects:
In the utility model valve plate received the promotion of cylinder, tightly be clamped between air inlet jacking block and the cylinder piston rod,, make source of the gas charge in the valve plate, observe the state of water in the water tank, impermeability that just can the visual inspection valve plate external source of the gas in the air inlet socket.The utility model is simple in structure; Easy to operate, at water tank bottom stationarity and the air inlet height and position that cushion block can be guaranteed valve plate is set, whole water tank can be set up deflecting roller, handle simultaneously; Form the movement test machine like this, shift onto flexibly in any workshop that needs to detect.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model preferred embodiment;
Fig. 2 is a gas circuit enlarged diagram in the utility model preferred embodiment.
Embodiment
In conjunction with accompanying drawing, preferred embodiment explains further details to the utility model.
The valve plate pressure testing machine, the parts that are mainly concerned with comprise: water tank 1, cylinder 2, pneumatic control valve 3, air inlet jacking block 4, cushion block 5, gas admittance valve 6, air inlet socket 7, cylinder jacking block 8, assembly cap 9, deflecting roller 10, handle 11, vent valve 12, gas circuit 13.
Water tank 1 is that end uncovered structure is arranged, and deflecting roller 10 is set on the bottom surface of water tank 1, makes water tank 1 form movable part, and in its side handle installation 11, operating personnel act on hand and can promote water tank 1 on the handle 11 flexibly to any place like this.
The bottom surface of water tank 1 is provided with cushion block 5, is used for horizontal support valve plate (not shown) to be detected.Be fixed with an air inlet jacking block 4 on the one side inwall of water tank 1, adopt the Cowhells rubber to process, exterior top surface is smooth, elasticity is strong, wear-resisting, change convenient, solid and seal when stressed.Relative side at air inlet jacking block 4 is fixed with a cylinder 2, and the cylinder body of cylinder 2 is positioned at water tank 1 outside; The piston rod of cylinder 2 stretches into the inside of water tank 1; On the termination of piston rod, connect cylinder jacking block 8 through piecing together cap 9, cylinder jacking block 8 cooperates with air inlet jacking block 4, grasps valve plate to be checked.Cylinder 2 is furnished with a cylinder control valve 3, is the switch that is used for control cylinder 2 air pressure.
The box body wall of water tank 1 has certain thickness, and cutter is established a gas circuit 13 on box body wall, and an end of gas circuit 13 connects air inlet socket 7 through gas admittance valve 6, and the other end extend into air inlet jacking block 4, forms to give valve plate inflation to be measured.A vent valve 12 is installed on air inlet jacking block 4, and vent valve communicates with gas circuit 13, opens the back and realizes exhaust.
The utility model is at first put into certain required water at water tank 1 in use, not have valve plate to be checked, but too much unsuitable, can produce the problem that can't accurately observe the seepage phenomenon too much.Then be placed on valve plate to be checked on the cushion block 5, an end withstands air inlet jacking block 4, valve plate to be checked treat that verify is identical with gas circuit 13; Open cylinder control valve 3, make the cylinder jacking block 8 of cylinder 2 clamp, withstand the valve plate other end to be checked; Open gas admittance valve 6 then, close vent valve 12, external air source is incorporated in the valve plate to be checked through air inlet socket 7; Whether have bubble produce, have to show that then valve plate to be checked has the seepage phenomenon if observing water this moment, do not have bubble to explain that then valve plate impermeability to be checked is qualified.Cross a few minutes leak tests and finish, close gas admittance valve 6, open vent valve 12 exhausts then, unclamp cylinder 2 at last, take out valve plate to be checked.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
