Abstract

The utility model discloses a three-way pressure checking apparatus, and the apparatus comprises a pressure gauge valve belonging to a three way connection. The three-way connection comprises a connector (91), a connector (92), and a connector (93), wherein the connector (91) is connected with oil source tube (2) through a valve (81); the connector (92) is connected with a pressure gauge (1); the connector (93) is connected with a hand-operated hydraulic pump (3) through a valve (82) and a flexible pipe (4); the hand-operated hydraulic pump (3) is connected with a flexible pipe (5) to a tube head (6); the tube head (6) is connected with a checking meter; and the checking work can be started. The apparatus is simple, convenient, and has high work efficiency. The checking system has less equipment, is portable and easy to carry by the checking personnel; checking work can be started on-site; and a filtering apparatus is arranged inside the hand-operated hydraulic pump to effectively filter the impurity from entering the checking system, thereby ensuring the checking precision.

Description

The threeway pressure checking device

Technical field

The utility model relates to a kind of calibration equipment, relates in particular to a kind of threeway pressure checking device.

Background technology

At present; Mostly the employed tensimeter of all trades and professions (pressure transducer, pressure switch) is to be threaded, and tensimeter all will regularly carry out verification, and general method of calibration is that the dismounting tensimeter carries out verification; Utilize not only inefficiency of this method; And frequent dismounting very easily causes loss, the leakage of oil of screw thread, in dismounting problems such as build-up of pressure table connecting portion leakage of oil easily, tensimeter damage at that time, greatly wasted manpower and materials.Simultaneously, in the pressure meter calibration process, the impurity of the residual inside of flexible member also easily along with medium flows into calibration equipment, causes to measure and is forbidden, even damage device, has a strong impact on the serviceable life and the sealing property of calibration equipment.

Summary of the invention

To the weak point of above-mentioned prior art, the utility model provides a kind of threeway pressure checking device.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of threeway pressure checking device, and said threeway pressure checking device comprises pressure gauge valve, tensimeter 1 and hydraulic hand-pump 3; Said pressure gauge valve is the pressure gauge valve of three-way connection, and said three-way connection is joint 91, joint 92, joint 93, and said joint 91 is provided with valve 81; Said valve 81 connects oil circuit source capsule 2; Said joint 92 connects tensimeter 1, and said joint 93 is provided with valve 82, and said valve 82 connects hydraulic hand-pump 3 through flexible pipe 4; Said hydraulic hand-pump 3 connects flexible pipe 5 to tube head 6, and said tube head 6 connects tester.

Further, said hydraulic hand-pump 3 hydraulic hand-pump 3 that is built-in filtration unit.

Further, be provided with spring and packoff in the said tube head 6.

Compared with prior art, the advantage of the utility model is: utilize the pressure gauge valve of three-way connection, when verification, directly put hose adapter 6; Feed pressure oil; Pressure oil gets into flexible pipe 5 to tube head 6 after accomplishing filtration through the filtration unit in the hydraulic hand-pump 3, and spring this moment drive packoff under the pressure oil effect moves backward; The mouth of pipe is opened, and oil circuit is connected.Utilize this kind mode simple and convenient, improved the verification work efficiency, guaranteed the verification progress.And this check system has few, the light advantage of equipment, and the verification personnel are easy to carry, and verification work can be carried out at the scene on the spot, and the built-in filtration unit of while hydraulic hand-pump effectively impurity screening does not get into check system, guarantees checking precision.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Embodiment

To combine accompanying drawing and embodiment that the utility model is done further to describe below.

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to Fig. 1, a kind of threeway pressure checking device, said threeway pressure checking device comprises pressure gauge valve, tensimeter 1 and hydraulic hand-pump 3; Said pressure gauge valve is the pressure gauge valve of three-way connection, and said three-way connection is joint 91, joint 92, joint 93, and said joint 91 is provided with valve 81; Said valve 81 connects oil circuit source capsule 2; Said joint 92 connects tensimeter 1, and said joint 93 is provided with valve 82, and said valve 82 connects hydraulic hand-pump 3 through flexible pipe 4; Said hydraulic hand-pump 3 connects flexible pipe 5 to tube head 6, is provided with spring and packoff in the said tube head 6 and connects tester.

During verification, close the valve 81 on the joint 91, open the valve 82 on the joint 93; The interface of tester is put tube head 6, feed pressure oil, after pressure oil filters completion through the filtration unit in the hydraulic hand-pump 3; Get in flexible pipe 5 tube heads 6; This moment, tube head 6 interior spring drive packoffs under the pressure oil effect moved backward, and the mouth of pipe is opened, and oil circuit is connected.Verification is closed the valve 82 on the joint 93 after accomplishing, and opens the valve 81 on the joint 91, and calibration equipment recovers normal condition.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
