Description
Technical field
The utility model is related to Engine Block Test technical field, particularly a kind of pressure gauge zero-bit point inspection device.
Background technology
When carrying out pressure test in automotive engine test bench, during stand above and below tested spreadsheet engine, pressure gauge begins
It is connected eventually with oil feed line, due to being influenceed by fluid negative pressure is remained in fuel feed pump, non-return-to-zero phenomenon usually occurs in pressure gauge, should
Phenomenon is still suffered from when oil pipe is connected to setup test on new engine, that is, is tested initial pressure value and forbidden, after directly influencing
Surface pressure test result.
In the existing technology for solving the inspection of pressure gauge zero point, such as Application No. 201310320749.X, entitled one
DN6 pressure meter three-way valves are planted, a triple valve are connected on pressure gauge by threeway transition joint, due to pressure gauge fuel feed pump
It is many that fuel feeding is realized using round end oil pipe, it is difficult to access threeway between round end oil pipe and pressure gauge under such attachment structure
Valve is, it is necessary to transform the joint of round end oil pipe, in addition it is also necessary to increase extra pipeline, and adapter sealing is poor.
Utility model content
The technical problems to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of suitable for circle
Tie-in oil pipe connected mode install pressure gauge, realize pressure gauge do not open and inspect under state zero point inspection.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of pressure gauge zero-bit point inspection device, including bolt, round end oil pipe and pressure gauge, round end oil pipe are sheathed on bolt
On, one end of bolt is twisted on manometric oil pipe, in addition to valve member, and the valve member is sealedly attached to bolt
The other end, at least one branch pipe and atmosphere of valve member；Valve member is mutually interconnected with offering one inside bolt
The cross through hole connected with the longitudinal hole is offered on logical longitudinal hole, bolt, cross through hole inside round end oil pipe with connecting
Logical, longitudinal hole inside manometric oil pipe with connecting.
Preferably, the bolt is hex bolts.Hex bolts is typical standard part, and this will not be increased from hex bolts
The cost of utility model, and easily transformed on the basis of existing equipment.
As optimal technical scheme, the longitudinal hole is located on the central shaft of bolt, longitudinal direction is opened up on center shaft logical
The convenient positioning in hole and processing, and the uniform wall thickness of longitudinal hole, the uniform force of hole wall everywhere.
It is further preferred that the central axis of the cross through hole and longitudinal hole.Cross through hole hangs down with longitudinal hole
It is straight to set, it is easy to processing, and structural member is in symmetric design, uniform force, Stability Analysis of Structures.
Action principle of the present utility model：
When automotive engine test bench is in running order, valve member is closed, when test terminates to change tested
During engine or when the same day starts test system pressure gauge zero point is examined first, by Open valve component by pressure gauge pressure
Power input port and atmosphere, because being passed through air in bolt, in round end oil pipe, make pressure gauge be under atmospheric pressure, realize pressure
Power table do not opened and inspect in working site in the case of zero reset, observation pressure gauge zero-bit whether be zeroed, such as be zeroed if close rotate
Valve member, now pressure gauge can be used for carrying out next round test, as pressure value is not zeroed, need to open and inspect or change pressure in time
Power table.
The utility model is used after said structure, is had the following technical effect that：
The utility model is simple in construction, it is adaptable to the improvement to existing equipment, increases connection on the basis of existing bolt
One valve member is used to connect air, a valve member is set up on existing can be achieved；The utility model connects
It is connected on pressure gauge without dismounting, manometric zero point inspection can be just realized by controlled valve component.
Brief description of the drawings
Fig. 1 shows structural representation of the present utility model.
Fig. 2 shows fractionation structural representation of the present utility model.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model..
As shown in figure 1, the utility model is related to bolt 1, valve body 2, valve 3, longitudinal hole 4, cross through hole 5, circle
