Abstract

The utility model discloses a clamping device for an air tightness test of a boss type stop valve. The clamping device comprises a sleeve, a threaded connection section matched with a test device is arranged at the lower end of the sleeve, a spring is arranged in the sleeve, a piston is arranged at the position, above the spring, inside the sleeve, a through hole is formed in the center of the piston, the lower end of the piston presses the spring, a stretching-in section matched with a test hole of the boss type stop valve is arranged at the upper end of the piston, the outer wall of the lower section of the piston and the outer wall of the stretching-in section are respectively provided with a sealing ring, and a clamping jaw is arranged at the upper end of the sleeve. The clamping device further comprises a locking sleeve, the outer wall of the piston is sleeved with the locking sleeve, the locking sleeve is screwed into and stretches into the sleeve, and the edge of the locking sleeve tightly presses the clamping jaw. The clamping device is novel in structural design, the boss type stop valve and the air tightness test device are connected through the clamping jaw, the sleeve, the piston, the spring and other structures, air tightness detection can be conveniently and quickly conducted on the boss type stop valve, and detection efficiency is improved.

Description

A kind of air tightness test clamping device of boss type stop valve
technical field:
The utility model relates to stop valve processing and manufacturing technology, relates in particular to a kind of air tightness test clamping device of boss type stop valve.
background technology:
Stop valve is a vitals in air-conditioning system, plays a part to open and close refrigerant circulation passage.Tradition stop valve installing plate bottom surface is welded with a copper pipe, the pipeline of this copper pipe end enlarging and air-conditioning system welds, form pipeline, there is now a kind of new stop valve, below stop valve body installing plate, welding is not taken over, directly a boss of design, the copper pipe of air-conditioning producer directly and this boss weld.Here it is boss type stop valve.
Before stop valve dispatches from the factory, all need to carry out airtight test, detect stop valve and whether have leakage.Under adapter type stop valve installing plate, be welded with a copper pipe, airtight test fixture clamps test by copper pipe; But boss type stop valve does not weld copper pipe,, there is a difficult point so how to solve the air tightness test of this boss valve in a stop valve boss just, and obviously traditional testing arrangement is no longer applicable.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of air tightness test clamping device of boss type stop valve, can to boss type stop valve, carry out clamping easily and fast, and coordinates the equipment of survey to detect, and has improved the efficiency detecting.
The technical solution of the utility model is as follows:
The air tightness test clamping device of boss type stop valve, comprise sleeve, it is characterized in that: the lower end of described sleeve is provided with the section of being threaded matching with testing equipment, in sleeve, be provided with spring, in the sleeve of spring top, be set with piston, the center of piston is provided with through hole, described spring is pushed down in piston lower end, the upper end of piston is provided with the dip section that boss type stop valve instrument connection matches, on piston hypomere outer wall and dip section outer wall, be respectively equipped with sealing ring, described sleeve upper end is provided with claw, also include lock sleeve, lock sleeve is set in piston outer wall and screws and stretches in sleeve, lock sleeve bead compresses described claw.
The air tightness test clamping device of described boss type stop valve, is characterized in that: described claw is U-shaped frame, and the side plate upper end level of U-shaped frame bends relatively.
The utility model has the advantages that:
The utility model structural design is novel, by structures such as claw, sleeve, piston, springs, form the linking between boss type stop valve and air-tightness testing device, can to boss type stop valve, carry out air-tightness detection easily and fast, improve the efficiency detecting.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to Fig. 1:
The air tightness test clamping device of boss type stop valve, comprise sleeve 1, the lower end of sleeve 1 is provided with the section of being threaded 2 matching with testing equipment, in sleeve 1, be provided with spring 3, in the sleeve of spring 3 tops, be provided with piston 4, the center of piston 4 is provided with through hole 9, piston 4 lower end pressing springs 3, the upper end of piston 4 is provided with the dip section 5 that boss type stop valve instrument connection matches, on piston hypomere outer wall and dip section 5 outer walls, be respectively equipped with sealing ring 6, sealing ring 6 is selected O type rubber seal, sleeve 1 upper end is provided with claw 7, also include lock sleeve 8, lock sleeve 8 is set in piston outer wall and screws and stretches in sleeve 1, lock sleeve 8 beads compress claw 7, lock sleeve 8 lower ends prop up piston interlude step.
Claw 7 is U-shaped frame, and the side plate upper end level of U-shaped frame bends relatively, and the lower wall of bending segment compresses the boss upper surface of boss type stop valve.
Concrete component processing and purposes: the preferential stainless steel material that adopts of piston 4 is wear-resisting.Sleeve 1 adopts brass material.
Claw 7 is formed by panel beating, has also increased baffle plate 7-1 structure on the side plate madial wall of claw 7, prevents that product from departing from clamping process, plays safety protection function, and baffle plate 7-1 is directly welded on claw 7.
The boss endoporus of boss type stop valve is deep into piston 4 dip section 5 heads, then firmly product is down pressed, piston moves downward, when moving to certain depth, boss type stop valve installing plate is turned in claw 7, make stop valve installing plate side prop up baffle plate 7-1, then unclamp hand, piston 4 resilience under the effect of spring, the resilience of Timing Belt movable property product makes stop valve installing plate front prop up the horizontal buckling section of claw 7, fixing lug boss type stop valve.
Between the dip section 5 of boss stop valve and piston upper end, by O type rubber seal, realize.
Sealing between piston 4 and sleeve 1 inwall is to realize by O type rubber seal equally.
The lifting position-limit of piston 4 in sleeve 1 realized by lock sleeve 8.
The section of being threaded 2 of sleeve 1 lower end, is used for connecting test equipment, and source of the gas is from this position access.
