Abstract
The utility model relates to a dysmorphism manometer cross -connection piece. Coupling nut's lower extreme is sealed fixed with the manometer interface of cross body through interior left -hand thread, and coupling nut's upper end is sealed fixed through interior right -hand thread and manometer, and the manometer communicates with each other with the cross body is sealed through coupling nut. Its simple structure, the fitting surface is few, and sealing connection is reliable.
Description
Technical field
The utility model belongs to pressure vessel connector, particularly a kind of special-shaped pressure meter four-way connector.
Background technology
In compressed natural gas carrier vehicle pipe-line system Pressure gauge connector comprise plane crisscross four-way pipe fitting,Silk elbows and special pressure table mount pad outside 90 ° pairs, between cross four-way pipe fitting and 90 ° of two outer elbowsAnd between 90 ° of two outer silk elbows and special pressure table mount pad and special pressure table mount pad and Pressure gauge itBetween be and be threaded, rely on to be wound around polytetrafluoro band and to seal, number of elements is many, seal point is many,Assemble reliability loaded down with trivial details and that be difficult to guarantee sealing. Meanwhile, this structure exists Pressure gauge dial plate towards cannot be pre-First definite shortcoming---after Pressure gauge screws, in the time of unexpected (cannot an observe) direction, only have and lean onAdjust that polytetrafluoro band is wound around number regulate, cannot ensure sealing, cause that to reveal hidden danger many, andThe leakage of natural gas, can cause the waste of the energy and the potential safety hazard that gas leakage explodes.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of special-shaped pressure meter four-way connector,It is simple in structure, and fitting surface is few, is tightly connected reliable.
The technical scheme in the invention for solving the technical problem is: in attaching nut's lower end is passed throughThe pressure gauge connection sealing of left-hand thread and four-way body is fixing, and attaching nut's upper end is by interior right-hand thread and pressureThe sealing of power table is fixing, and Pressure gauge communicates with the sealing of four-way body by attaching nut.
1), simple in structure the utlity model has following advantages:, fitting surface is few, and leak point is few, sealing connectsConnect reliable; 2), because Pressure gauge attaching nut adopts left and right hand thread structure, can ensure pressure gaugeDish assembles towards optional position, the convenient Pressure gauge indicating value of observing; 3), four-way body adopts octagonal to cutFace structure, facilitates forging molding, and lightweight, and stock utilization is high.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view.
Detailed description of the invention
As shown in Figure 1, 2, attaching nut 3 lower end is by the Pressure gauge of interior left-hand thread 2 and four-way body 1Sealing joint is fixed, and attaching nut 3 upper end is fixing with Pressure gauge 6 sealings by interior right-hand thread 4, pressureTable 6 communicates with 1 sealing of four-way body by attaching nut 3.
The cross section of described four-way body 1 is octagonal. Facilitate forging molding, and lightweight, materialUtilization rate is high.
The material of described four-way body 1 is S304 stainless steel. Metallographic structure densification, carries out after completingThe hydraulic pressure ruggedness test of 30MPa, meets high pressure working condition requirement.
Described attaching nut's 3 material is S304 stainless steel.
