Abstract

The utility model relates to a performance testing special clamp for a four-way change valve of an air conditioner. The utility model is characterized in that the utility model comprises a main bottom plate, a basal plate, a corresponding plate of a needle plate, a draw rod, a draw rod nut and the needle plate, two lower side ventilating pipes, an upper middle ventilating pipe, a lower middle ventilating pipe, a fixed casing tube of the lower middle ventilating pipe and a valve blocking frame assembly, wherein the basal plate is arranged on a rail of the main bottom plate; the needle plate is arranged on the basal plate; the four ventilating pipes are flexibly connected with the needle plate through an O-shaped rubber ring respectively; two cylinders for pushing a change valve and a basal plate assembly are respectively arranged on the main bottom plate. The manual installation is replaced by using the air-actuated clamp. Thus, the labor intensity is lowered and the efficiency is raised. Because the ventilating pipes are in flexible connection, the damage to the tested valve in testing is prevented.

Description

Air conditioner four-way change-over valve performance test unit clamp

The utility model relates to a kind of air conditioner four-way change-over valve used unit clamp when performance test.

Four-way change-over valve is a critical piece of realizing refrigeration and the conversion of heat pump heat-production functions in the air conditioner, four-way change-over valve quality quality has directly influenced air conditioner machine performance and reliability, therefore need four-way change-over valve is carried out performance test, it comprises minimum commutation pressure test, maximum commutation pressure test, the internal leakage test, yet, at present, four-way change-over valve adopts artificial the installation, and manual method detects, like this, labour intensity is big, inefficiency, though there is producer to adopt pneumatic chuck to install, the parts of tracheae are to adopt to be rigidly connected because chuck and tested valve gate test pipe promptly are called all, therefore, tested four-way gas reversal valve is often broken.

The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of employing air-actuated jaw to be provided, and is easy for installation and the air conditioner four-way change-over valve performance test unit clamp that flexibly connects snorkel arranged.

The technical solution of the utility model is achieved like this, it includes main floor, substrate, the needle plate respective panels, pull bar, pull-rod nut, needle plate, under survey snorkel, last Center Vent tube, following Center Vent tube, following Center Vent tube fixed sleeving and valve backrest plate, the left front thick stick of valve guard frame, the valve guard frame component of the right front thick stick of valve guard frame, substrate places on the guide rail of main floor by bolt, needle plate places on the substrate by bolt, downside, down, following Center Vent tube, four pipes of following Center Vent tube fixed sleeving flexibly connect by rubber " O " type circle and needle plate separately, fixedly the cylinder of tested air conditioner four-way change-over valve is by being bolted on the main floor, be used for promoting to comprise substrate, needle plate and downside, in going up, following Center Vent tube, the cylinder B that the valve seat substrate plate assembly of following Center Vent tube fixed sleeving moves forward and backward by bolt on main floor, cylinder stroke adjustment shaft bar and cylinder stroke regulating lever place on the substrate plate, are used to regulate cylinder A.

The cylinder A that the utility model adopts is two-way mobile cylinder, by connecting substrate, board unit and four snorkel integral body are moved forward and backward, realize that the gas circuit of tested four-way change-over valve connects, cylinder B promotes sliding divider assembly and moves forward and backward, with tested valve body positioning and fixing, adopt this air-actuated jaw to replace artificial installation, labour intensity reduces, efficient improves, snorkel has adopted and has flexibly connected, and during test, has prevented that tested valve is damaged.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural front view;

Fig. 2 is the utility model structure vertical view;

Fig. 3 is the snorkel structural representation.

Shown in Fig. 1～3, the utility model mainly contains main floor 1, substrate 2, needle plate respective panels 3, pull bar 4, pull-rod nut 5, needle plate 6, downside snorkel 7,8, last Center Vent tube 9, following Center Vent tube reaches following Center Vent tube fixed sleeving 10 and comprises by valve backrest plate 12, the left front thick stick 13 of valve guard frame, the valve guard frame component of the right front thick stick 14 of valve guard frame, substrate 2 places on the guide rail of main floor 1 by bolt, needle plate 6 places on the substrate 2 by bolt, downside snorkel 7,8, last Center Vent tube 9, following Center Vent tube reaches Center Vent tube fixed sleeving 10 down, by shown in Figure 3, respectively rubber " O " the type circle by separately 19 flexibly connects with needle plate 6, fixedly the tested air conditioner four-way change-over valve is numbered 18 cylinder B by being bolted on the main floor 1, be used for promoting to comprise substrate, during needle plate reaches and goes up, down, the downside snorkel and down 17 the cylinder A of being numbered that moves forward and backward of the board unit of Center Vent tube fixed muffle place on the main floor 1 by bolt, cylinder stroke adjustment shaft bar 16 and cylinder stroke regulating lever 15 place on the main floor 1.
