Abstract
A kind of pvc pipe joints differential including differential body and is set to multiple holding screws on differential body periphery, and holding screw is correspondingly connected with the expected briquetting accordingly coordinated；Wherein differential body periphery is uniformly arranged multiple holes, holding screw and briquetting correspondence across the multiple hole, is provided with sealing ring on diameter in differential body, the differential is simple in structure, simple installation, anti-pipe leakage.
Description
Technical field
The utility model is related to casting fields, and in particular to a kind of pvc pipe joints differential, for pvc pipe socket pipes
The connection fastening of part connector.
Background technology
Pvc pipe-line systems are that pipe-line system is commonly used in present water-carriage system.Existing pvc pipe-line systems are in pipeline anti-offability side
There is the defects of certain in face, and under pipeline water delivery pressure, formation variation and water hammering, pipeline has the wind that comes off with bellmouth pipe fitting
Danger, so as to cause leak.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of pvc pipe joints differential, structure letter
It is single, simple installation, preventing water leakage.
The utility model provides a kind of pvc pipe joints differential, including differential body and is set to the more of differential body periphery
A holding screw, holding screw are correspondingly connected with the expected briquetting accordingly coordinated；Wherein differential body periphery is uniformly arranged multiple holes, tightly
Screw and briquetting correspondence are determined across the multiple hole, and sealing ring is provided on diameter in differential body.
Preferably, it is provided with knob on the briquetting.
Preferably, holding screw has groove.
Preferably, it is broken when holding screw head reaches threshold fastening pressure in groove.
It is good that the pvc pipe joint differentials of the utility model reach sealing effect in type of attachment using outer means of press seals, when
When fastening pressure reaches requirement, briquetting knob has been fitted close with pvc pipeline outer walls, and length travel will not occur again for pvc pipelines,
So as to avoid shedding leak risk, the pvc pipe joint differentials are simple in structure, simple installation, preventing water leakage.

Fig. 3 is pvc pipe joint differential mounting structure schematic diagrams
Specific embodiment
The following detailed description of the specific implementation of the utility model, it is necessary to it is indicated herein to be, implement to be only intended to below
The further explanation of the utility model, it is impossible to be interpreted as the limitation to scope of protection of the utility model, the skilled people of the field technology
Some nonessential modifications and adaptations that member makes the utility model according to above-mentioned the utility model content, still fall within this reality
With novel protection domain.
The utility model provides a kind of pvc pipe joints differential, as shown in Figs. 1-3, external pressure is used in type of attachment
Sealing by differential 1 and the compacting pressure of sealing ring, makes bellmouth pipe fitting joint reach sealing effect.To prevent shedding,
There are a certain number of holding screws 3 and the briquetting 2 accordingly coordinated in connector differential periphery, after differential 1 and sealing ring compress, adjusts
Holding screw 3 pushes briquetting 2 and tube contacts, and 2 upper pressing tooth of briquetting is bumped under pressure in pvc pipeline outer walls, when tight
When solid pressure power reaches 90ft-lb, 3 head of holding screw is broken from head groove, fastening force is prompted to reach requirement, it is impossible to again
Continue reinforcing fastening, so as to which fastening force be avoided to be damaged to pvc pipelines greatly very much.When fastening pressure reaches requirement, briquetting pressure
Tooth has been fitted close with pvc pipeline outer walls, and length travel will not occur again for pvc pipelines, so as to avoid shedding leak wind
Danger.
Although for illustrative purposes, it has been described that the illustrative embodiments of the utility model, the skill of this field
Art personnel will be understood that, can be in shape in the case of the scope and spirit for not departing from utility model disclosed in appended claims
The change for carrying out various modifications, adding and replacing in formula and details etc., and all these changes should all belong to the utility model institute
Attached scope of the claims, and each step in each department of product and method of the requires of the utility model protection,
Form that can be in any combination is combined.Therefore, it is not to the description of the embodiment disclosed in the utility model
In order to limit the scope of the utility model, but for describing the utility model.Correspondingly, the scope of the utility model not by with
The limitation of upper embodiment, but be defined by claim or its equivalent.
