Furthermore, the device is reasonable in design, light in weight, convenient to use, and easy to move.
Description
Technical field
The utility model relates to a kind of retaining valve pressure tester, belongs to field of machining.
Background technology
In fields such as chemical industry, pharmacy, the use of retaining valve is seen everywhere.Retaining valve is that fluid can only be along inlet flow, the device that the outlet medium but can't reflux.The principle of work of spring retaining valve is, liquid flows into valve body by import, relies on the spring controlled flap of pressure jack-up, and after pressure disappeared, spring force was depressed flap, and sealing liquid flows backwards.Yet, in the manufacturing and testing process of retaining valve, the pressure that can bear in order to obtain retaining valve, existing method commonly used is to use vernier caliper measurement spring compression amount, and then carry out conversion pressure.Such indirect measurement method, the speed of measurement is slow, and the error of measurement is also larger.
Therefore, in order to solve above technical matters, be necessary existing design is improved, design a kind of retaining valve pressure tester, this device is simple to the retaining valve installation way, can carry out accurate pressure measurement to retaining valve, and properties of product are more reliable.The use of this device has alleviated workman's labour intensity, has improved work efficiency, has reduced measuring error.In addition, this pressure tester reasonable in design, easy to use, the device design is light and handy, is convenient to mobile.
The utility model content
in order to overcome the defective that exists in background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of retaining valve pressure tester, comprise cover plate, gib screw, riser, base plate, side plate and body, two of the left and right of described body are fixed with respectively riser on the side, the front of described body is provided with cover plate, described cover plate is fixed on body by gib screw, the back of described body is provided with side plate, described side plate is fixed on body by gib screw, the center of side plate is provided with guide hole, top oil hole one and the oil hole two of being provided with of described body, be provided with O type circle two between described body and cover plate, be provided with O type circle one between described body and side plate.
A kind of retaining valve pressure tester that the utility model is related, this device is simple to the retaining valve installation way, can carry out accurate pressure measurement to retaining valve, and properties of product are more reliable.The use of this device has alleviated workman's labour intensity, has improved work efficiency, has reduced measuring error.In addition, this pressure tester reasonable in design, easy to use, the device design is light and handy, is convenient to mobile.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation one of a kind of retaining valve pressure tester of the utility model;
Fig. 2 is the structural representation two of a kind of retaining valve pressure tester of the utility model;
Fig. 3 is along the cut-open view of A-A direction in Fig. 2;
Fig. 4 is the use status architecture schematic diagram of a kind of retaining valve pressure tester of the utility model;
Wherein: 1, oil hole one; 2, oil hole two; 3, cover plate; 4, gib screw; 5, riser; 6, base plate; 7, side plate; 8, guide hole; 9, O type circle one; 10, O type circle two; 11, retaining valve; 12, body.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.The schematic diagram of accompanying drawing for simplifying basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
see also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of retaining valve pressure tester, comprise cover plate 3, gib screw 4, riser 5, base plate 6, side plate 7 and body 12, two of the left and right of described body 12 are fixed with respectively riser 5 on the side, the front of described body 12 is provided with cover plate 3, described cover plate 3 is fixed on body 12 by gib screw 4, the back of described body 12 is provided with side plate 7, described side plate 7 is fixed on body 12 by gib screw 4, the center of side plate 7 is provided with guide hole 8, top oil hole 1 and the oil hole 22 of being provided with of described body 12, be provided with O type circle 2 10 between described body 12 and cover plate 3, be provided with O type circle 1 between described body 12 and side plate 7.
A kind of retaining valve pressure tester that the utility model is related, in use, at first, open cover plate 3, retaining valve 11 is put into pressure tester, make the outlet of retaining valve just pass the guide hole 8 of establishing on side plate 7, then with gib screw 4 after this cover plate 3 is fixed on body,, from oil hole 22 beginning oilings, when oil hole 1 has oil to flow out, the oiling oil pressure of oil hole 22, needed pressure when being exactly the valve open of this retaining valve; If from oil hole one 1 oilings, see whether oil hole 22 has oil to flow out, the maximum that can be used for detecting retaining valve is born the size of pressure and the oil impregnate amount under certain pressure.This device is simple to the retaining valve installation way, can carry out accurate pressure measurement to retaining valve, and properties of product are more reliable.The use of this device has alleviated workman's labour intensity, has improved work efficiency, has reduced measuring error.In addition, this pressure tester reasonable in design, easy to use, the device design is light and handy, is convenient to mobile.
