Abstract
The utility model discloses an assembly structure for an O-shaped rubber sealing ring on a valve spool. The assembly structure comprises the valve spool and the O-shaped rubber sealing ring and is characterized by further comprising a base made of plastics, a plurality of pins are fixedly connected onto the base, the valve spool is inserted onto one pin through an inner hole of the valve spool, a mandrel is sleeved at the upper end of the valve spool, the top of the mandrel is of a spherical structure, the middle of the mandrel is of a conical structure, and the O-shaped rubber sealing ring is sleeved outside the mandrel and slides into a valve spool groove on the valve spool from the mandrel. The assembly structure is simple, easy to assemble and operate and high in practicability, and the labor intensity of staff is greatly reduced.
Description
Technical field
The utility model relates to, and mainly is the assembly structure of O type rubber seal on a kind of spool.
Background technology
Stop valve is a vitals on the air-conditioning system, plays a part to open and close refrigerant circulation passage, and realize this function be by the operation spool open, closing passage.Spool is arranged on the stop valve body inner chamber, in operation spool process, guarantee the sealing of spool, and does not leak assurance valve inner passage.Sealing between spool and valve body realizes by O shape rubber seal, therefore O type rubber seal is assembled into the procedure that is absolutely necessary on the spool.
Originally adopt manual operations, for O type rubber seal is assembled in the groove of spool, be inserted in outside the spool after O shape circle need to being expanded, then pin another section of O type rubber seal with the another hand and in groove, slip into until in the whole O type rubber seal embedded groove.Have following problem: 1, O type rubber seal slips in the process, and employee's finger nail is the broken O type rubber seal of button easily, affects product quality; 2, owing to need hand to pin the expansion of O type rubber seal, the employee is tired easily; 3, in the actual assembled, O type rubber seal scribbles lubricating oil, is difficult for assembling, and productive temp is slow, and finger is pressed in spool screw thread place, hinders easily hand.
The utility model content
Technical problem to be solved in the utility model provides the assembly structure of O type rubber seal on a kind of spool, and it is simple in structure, and assembly manipulation is practical easily, greatly reduces staff labor intensity.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The assembly structure of O type rubber seal on a kind of spool, include spool, O type rubber seal, it is characterized in that: also include the base of being made by plastic material, be fixedly connected with a plurality of latches on the described base, described spool is inserted on the latch by the spool endoporus, cover has a plug on the upper end of described spool, described plug top structure spherical in shape, the centre of plug is conical structure, described O type rubber seal is enclosed within mandrel outer, in the spool groove of O type rubber seal on from landing on the plug to spool.
Described plug is made by copper product.
Plug project organization in the utility model is unique, the diameter of plug upper end is less than O type rubber seal internal diameter, can fast O type rubber seal be slipped into, the plug interstage is designed to conical structure, having certain gradient, is in order to play the guiding role, in slipping into process, expand slowly O type rubber seal, until slide in the spool groove of spool.Plug top design globulate, easy during dress O type rubber seal, play the guiding role.
Base adopts plastic material to process in the utility model, and quality is low weight; Plug adopts copper product to process, and can prevent from damaging with spool.
Latch is designed to mate with the spool endoporus of spool in the utility model, after spool is placed, guarantees steadily not rock, and does not tilt.
The bottom of plug is concordant with a step surface of spool in the utility model, and size is consistent with the spool groove of spool, and O type rubber seal is steadily slipped in the groove.
The utility model has the advantages that:
The utility model is simple in structure, and assembly manipulation is practical easily, greatly reduces staff labor intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the assembly structure of O type rubber seal on a kind of spool, include spool 1, O type rubber seal 2, also include the base 3 of being made by plastic material, be fixedly connected with a plurality of latches 4 on the described base 3, described spool 1 is inserted on the latch 4 by the spool endoporus, cover has a plug 5 on the upper end of described spool 1, described plug 5 tops structure 6 spherical in shape, the centre of plug 5 is conical structure 7, described O type rubber seal 2 is enclosed within outside the plug 5, in the spool groove of O type rubber seal 2 on from landing on the plug 5 to spool.
Described plug 5 is made by copper product.
During operation, O type rubber seal 2 is expanded landing gradually outside plug 5, and last landing seals to the spool groove of spool 1.
Claims (2)
1. the assembly structure of O type rubber seal on the spool, include spool, O type rubber seal, it is characterized in that: also include the base of being made by plastic material, be fixedly connected with a plurality of latches on the described base, described spool is inserted on the latch by the spool endoporus, cover has a plug on the upper end of described spool, described plug top structure spherical in shape, the centre of plug is conical structure, described O type rubber seal is enclosed within mandrel outer, in the spool groove of O type rubber seal on from landing on the plug to spool.
