Description
Technical field：
It the utility model is related to a kind of fixture, more particularly to the hydrostatic test radial direction fixture of heavy caliber PVC.
Background technology：
Polymer pipe especially pvc pipe has excellent combination property, such as light, energy-conservation, corrosion-resistant, easy to install, cost
It is low, it is widely used in the fields such as gas transmission, water delivery.Polymer pipe processing turns into one of national mainstay industry.
At present, PVC connection is typically the connection of R sockets cushion rubber and the gluing connected mode of pipe fitting.The mouth in tubing production
Footpath has slight change, it is contemplated that in the project installation of reality and in use, whether leak is exactly key point, as installed
Leak afterwards, the consequence brought are very serious.So the test before tubing construction is with regard to most important.PVC is constant for a long time
The maximum pressure value of pressure-resistant time and momentary breakdown under internal pressure and steady temperature, it is that tubing production firm and testing agency are necessary
Detection project, detection machine need to keep certain constant pressure in the course of the work for a long time, operating pressure is big, precision and
Sealing requirements are high, therefore these products are mostly costly, the test device suitable for heavy caliber PVC be even more it is few again
It is few.
Utility model content：
The purpose of this utility model is to provide features simple structure, and sealing property and accuracy are high, suitable for heavy caliber PVC
The hydrostatic test radial direction fixture of tubing.
The utility model is implemented by following technical scheme：A kind of hydrostatic test radial direction fixture of heavy caliber PVC, it is wrapped
Include top sealing device and lower seal apparatus；The top sealing device includes upper pipe sleeve, upper cover and upper fixture body, in the upper cover side wall
On using the upper cover vertical centerline as the center of circle be fixed with three upper envelope fixed ears into even circumferential distribution, it is described on
End socket bottom stretches out provided with ring flange, and the upper pipe sleeve top stretches out connects disk provided with method, the upper cover and described
Upper sleeve pipe is fixedly connected by flange, and the upper fixture body includes the lobe of structure identical at least three；The lobe passes through spiral shell
Tether and connect clamping and form a full circle, the lobe is the concave character type structure of arc-shaped, groove wrap up the upper sleeve pipe with it is described
The ring flange of upper cover, the upper cover top are communicated with water injection pipe, forcing pipe and the blast pipe of the upper cover inner chamber；Institute
Stating lower seal apparatus includes lower pipe sleeve, low head and lower clamp body, and the low head top stretches out provided with ring flange, under described
Pipe sleeve bottom stretches out connects disk provided with method, and the low head is fixedly connected with the setting of casing by flange, the lower clamp
Body includes the lobe of structure identical at least three；The lobe clamps to form a full circle, the folder by the bolt connection
Valve is the concave character type structure of arc-shaped, and groove wraps up the ring flange of the setting of casing and the low head, the low head bottom
Provided with support；It also includes the upper envelope fixed ear, lower envelope fixed ear and the bolt；It is fixed in the top sealing device side wall
Provided with the upper envelope fixed ear of more than three, be provided with the lower seal apparatus side wall with it is described on seal fixed ear quantity, position
The lower envelope fixed ear corresponding to putting, sealed on described in fixed ear and the lower envelope fixed ear fixed logical corresponding to offering
Hole, the upper envelope fixed ear and the lower envelope fixed ear through bolt described in the fixed via by being attached.
The advantages of the utility model：The apparatus structure is simple, is easily installed, and sealing property and positioning performance are excellent, detection
As a result it is more accurate.
