Abstract
The utility model discloses a high pressure switching -over device for cross valve belongs to cross valve detection device technical field. The on -line screen storage device comprises a base, be provided with connecting plate and support on the base, peg graft on the connecting plate have many with the plug of the pipeline joint of cross valve, the plug includes intake pipe, outlet duct and stifled pipe, a side of support is installed and to be followed the gliding valve body mount pad of vertical orientation, and the actuating cylinder that drives who is used for driving the removal of valve body mount pad is installed at the top of support. The utility model discloses switching -over device simple structure, convenient operation has saved operating time through this detection method, has improved the accuracy that detects.
Description
Technical field
The utility model relates to a kind of high pressure reversing arrangement for four-way valve, belongs to four-way valve pick-up unit technical field.
Background technology
One of four-way valve main performance is commutation reliable in action, the switching that four-way valve commutation realizes air-conditioning system refrigeration and heats, therefore, four-way valve commutation ability directly affects whole air-conditioning system, especially when D pipe passes into high pressure gas, if four-way valve can realize free commutation, then illustrate that four-way valve commutation ability is reliable.But in prior art, to the switch operation of four-way valve be all adopt artificial hand-held detection fixture engage with the pipeline of four-way valve, then starting outfit carries out inflating and bleeding, this mode not only operating efficiency is low, and detect the joint undertighten of fixture and four-way valve, easy gas leakage, causes detection inaccurate.
Utility model content
For solving the problem, the utility model provides a kind of structure simple, easy to operate four-way valve high pressure reversing arrangement and detection method.
The technical scheme that the utility model adopts for its problem of solution is:
For a high pressure reversing arrangement for four-way valve, comprise base, described base is provided with gusset and support; Described gusset is plugged with the many plugs engaged with the pipeline of four-way valve, described plug comprises draft tube, escape pipe and plugging; One side of described support is provided with the valve body mount pad that can slide along the longitudinal direction, and the top of support is provided with the driving cylinder for driving the movement of valve body mount pad.
Preferably, the side of described support is provided with the slide rail for the described valve body mount pad that is slidably installed.
Preferably, described valve body mount pad comprise base plate and be arranged on the limited block at described base plate four angles.
Preferably, the tube wall of described draft tube, escape pipe and plugging is provided with O-ring seal.
The beneficial effects of the utility model are: structure is simple, easy to operate, saves the running time, improves the accuracy of detection.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is operating diagram of the present utility model.
In figure: 1, base; 2, gusset; 3, draft tube; 4, escape pipe; 5, plugging; 6, O-ring seal; 7, support; 8, valve body mount pad; 9, base plate; 10, limited block; 11, cylinder is driven; 12, slide rail; 13, D pipe; 14, E pipe; 15, C pipe; 16, S pipe.
Embodiment
A kind of high pressure reversing arrangement for four-way valve as shown in Figure 1, comprises base 1, described base 1 is provided with gusset 2 and support 7; Described gusset 2 is plugged with the many plugs engaged with the pipeline of four-way valve, described plug comprises draft tube 3 and escape pipe 4, also comprises the plugging 5 for shutoff four-way valve E, C pipe.The tube wall of described draft tube 3, escape pipe 4 and plugging 5 is provided with O-ring seal 6, to guarantee the impermeability after being combined with four-way valve.One side of described support 7 is provided with the valve body mount pad 8 that can slide along the longitudinal direction, and described valve body mount pad 8 comprises base plate 9 and is arranged on the limited block 10 at described base plate 9 four angles.The top of support 7 is provided with the driving cylinder 11 for driving valve body mount pad 8 movement, and the side of described support 7 is provided with the slide rail 12 for the described valve body mount pad 8 that is slidably installed.
As shown in Figure 2, the commutation Cleaning Principle of four-way valve is, after four-way valve is installed in valve body mount pad 8, operator's starter gear, drives cylinder 11 to drive valve body mount pad 8 to move down, and each bar adapter on four-way valve is engaged with plug respectively.Four-way valve generally comprises four adapters, is called D pipe 13, E pipe 14, C pipe 15, S pipe 16, D pipe 13 engage with draft tube 3, and be transfused to the high pressure gas of 2.0 ~ 3.5MPa; E pipe 14, C pipe 15 can engage with plugging 5, or arrange pressure switch in plugging 5, for detecting the air pressure in E pipe 14, C pipe 15; S pipe 16 can engage with escape pipe 4, and escape pipe 4 can connect exhaust box, reduces the noise produced when S pipe 16 is given vent to anger.The commutation of four-way valve coil power on/off realizes E pipe 14 and is transformed into C pipe 15 and S pipe 16 conducting with S pipe 16 conducting, E pipe 14, C pipe 15 end pressure switch are for judging whether commutation completes, commutation process is by the coil power on/off pilot valve commutation action be positioned on four-way valve, and then pilot valve drives main valve to complete, four-way valve can also be monitored whether there is noise bad while commutation, commutation number of times and arranging by equipment touch-screen commutating period.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
