Abstract
The utility model specifically relates to a valve pressure testing device, solving the problems that in pressure testing of a valve at present, time and labor are wasted, and pressure testing efficiency is influenced. The valve pressure testing device comprises a support, the support is fixedly provided with a main pipe, one end of the main pipe is fixedly provided with a steel plate, the steel plate is provided with a galvanized short pipe communicated with the main pipe, a main pipe flange is welded to the other end of the main pipe, the side wall of the main pipe is provided with a plurality of branch pipes of different specifications which are communicated with the main pipe, the other ends of the branch pipes are connected with branch pipe flanges or threads. The valve pressure testing device is reasonable and reliable in structural design, saves time and labor in a pressure testing process, effectively reduces the labor intensity of constructors, effectively improve pressure testing efficiency, and has the advantages of simple structure, convenient operation and low cost.
Description
Technical field
The utility model relates to construction and uses pressure testing device, is specially a valve pressure testing device.
Background technology
Valve should be done intensity and leak test before installing.Test should spot-check 10% in every batch of (the same trade mark, same model, same specification) quantity, and is no less than one.For being installed in the closed circuit valve that plays cutting action on the main pipe, should do intensity and leak test one by one; The intensity of valve and leak test should meet following provisions: the Strengh testing pressure of valve is 1.5 times of nominal pressure; Leak test pressure is 1.1 times of nominal pressure; Test pressure remains unchanged the duration planted agent, and housing filler and flap sealing surface ne-leakage are qualified.
Traditional valve pressure testing mode is: will connect together (valve quantity is many also can carry out in batches) with the valve of the nominal pressure same specification quantity according to code requirement, and then, the valve that connects will be connected in the method for pressure testing on the test pump again.
There are the following problems for this method: the pressure testing simultaneously of the valve of different size, have the valve of how many specifications must the pressure testing how many times, and valve and valve be connected and dismantle inconvenient.
Summary of the invention
The utility model exists to waste time and energy when having the valve pressure testing now in order to solve influences the problem of pressure testing efficient, and a kind of valve pressure testing device is provided.
The utility model is to adopt following technical scheme to realize: the valve pressure testing device, comprise support, the person in charge is fixedly arranged on the support, an end of being responsible for fixedly has steel plate, and steel plate is provided with and is responsible for the zinc-plated short tube that is communicated with, the other end of being responsible for is welded with person in charge's flange, and the person in charge's sidewall is provided with some communicating with it and arm that specification is different, and the other end of arm is connected with and props up pipe flange or a mantle fiber.
When carrying out the valve pressure testing, to need the valve of the same nominal pressure of pressure testing to be contained in respectively on the corresponding arm according to the specification size, to there be Zhi Guanyong pipe cap or the blank flange shutoff of mounted valve, connect test pump in the outer end of zinc-plated short tube subsequently, get final product pressure testing, existing to waste time and energy when having overcome existing valve pressure testing influences the problem of pressure testing efficient.
The utility model reasonable in design is reliable, and the pressure testing process is time saving and energy saving, has alleviated workmen's labour intensity effectively, and has improved pressure testing efficient effectively, has advantage simple in structure, easy to operate and that cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic side view of Fig. 1.
Among the figure: the 1-support, 2-is responsible for, the 3-steel plate, the zinc-plated short tube of 4-, 5-is responsible for flange, 6-arm.
Embodiment
The valve pressure testing device, comprise support 1, fixedly have on the support 1 and be responsible for 2, an end of the person in charge 2 fixedly has steel plate 3, and steel plate 3 is provided with and is responsible for the 2 zinc-plated short tubes 4 that are communicated with, be responsible for 2 the other end and be welded with and be responsible for flange 5, be responsible for 2 sidewall and be provided with some communicating with it and arm 6 that specification is different, the other end of arm 2 is connected with and props up pipe flange or a mantle fiber.
In the specific implementation process because the specification difference of valve, valve seal material therefor difference, the valve pressure testing duration is also different thereupon, should be according to code requirement be the whole valves test duration with the longest valve of pressure testing duration; The valve of different nominal pressures pressure testing simultaneously is because test pressure is sample not.
Claims (1)
1. valve pressure testing device, it is characterized in that: comprise support (1), support (1) is gone up fixedly the person in charge (2), an end of being responsible for (2) fixedly has steel plate (3), and steel plate (3) is provided with and is responsible for the zinc-plated short tube (4) that (2) are communicated with, the other end of being responsible for (2) is welded with is responsible for flange (5), and the sidewall of being responsible for (2) is provided with some communicating with it and arm (6) that specification is different, and the other end of arm (2) is connected with and props up pipe flange or a mantle fiber.
