Abstract
The utility model discloses a valve pressure measuring tool which comprises a cylinder body, wherein the upper end of the cylinder body is sealed; a screw rod penetrates through the upper end of the cylinder body from top to bottom and extends into the inner part of the cylinder body; the screw rod and the inner wall of the cylinder body are in thread fit; the upper end of the screw rod is provided with a handle; a piston capable of moving up and down along the inner wall of the cylinder body is fixedly installed on the lower end of the screw rod; a spring is connected between the upper end of the piston and the inner side surface of the end part of the cylinder body; and the cylinder body is provided with two axial through holes, wherein one axial through hole is a water injection hole, and a pressure gage is installed and sealed at the opening part of the other axial through hole. The valve pressure measuring tool provided by the utility model is simple in structure, is light in weight, has a small volume, is convenient to carry, is small in occupation space, is very convenient in mounting and dismounting, can perform pressure measuring on a valve anytime and anywhere, and has high maneuverability.
Description
Technical field
The utility model relates to a kind of valve pressure measurement frock.
Background technology
Valve all will carry out the sale of just dispatching from the factory after the water pressure test passes before dispatching from the factory.Present known valve PMU is divided into large, medium and small type pressure testing machine according to the difference of valve size, directly supplies water to valve and carries out pressure test.The shortcoming of above-mentioned Valve pressure test device is: pressure testing machine weight is big, volume is big, even small-sized pressure testing machine, also about 800 kilograms, therefore inconvenience when moving and use has reduced testing efficiency to its weight, and is big because of volume simultaneously, occupied bigger space.When next valve sale and use on-the-spot test, because test machine weight is big, volume is big, carries very inconvenience, so often can't carry out the scene valve pressure is tested.
The utility model content
The purpose of the utility model provides a kind of valve pressure measurement frock, solves that existing Valve pressure test device weight is big, volume big, inconvenient problem with use.
The technical scheme of the utility model is following:
A kind of valve pressure measurement frock; Comprise cylindrical shell, the upper end closed of said cylindrical shell is characterized in that: have screw rod to pass the upper end of cylindrical shell from top to bottom and extend to the inside of cylindrical shell; Described screw rod cooperates with the inner thread of cylindrical shell; The upper end of screw rod has handle, and the lower end of screw rod is installed with the piston that can move up and down along cylinder inboard wall, is connected with spring between the medial surface of the upper end of said piston and cylindrical shell end; Described cylindrical shell is provided with two axially extending bores, and one of them axially extending bore is a water injection hole, and tensimeter is installed and be sealed with to the oral area of another axially extending bore.
Described valve pressure measurement frock is characterized in that: the outer of said cylindrical shell bottom is equipped with ring flange.
Described valve pressure measurement frock is characterized in that: be provided with O-ring seal before described piston and the cylinder inboard wall.
The beneficial effect of the utility model:
The utility model is simple in structure, in light weight, volume is little, easy to carry, and it is little to take up room, and installation and removal are all very convenient, can carry out pressure test, mobility strong to valve whenever and wherever possible.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of valve pressure measurement frock comprises cylindrical shell 1; The upper end closed of cylindrical shell 1 has screw rod 2 to pass the upper end of cylindrical shell 1 from top to bottom and extends to the inside of cylindrical shell 1, and screw rod 2 cooperates with the inner thread of cylindrical shell 1; The upper end of screw rod 2 has handle 3; The lower end of screw rod 2 is installed with the piston 4 that can move up and down along the inwall of cylindrical shell 1, is connected with spring 5 between the medial surface of the upper end of piston 4 and cylindrical shell 1 end, plays position-limiting action; Cylindrical shell 1 is provided with two axially extending bores, and one of them axially extending bore is a water injection hole 6, and tensimeter 8 is installed and be sealed with to the oral area of another axially extending bore 7.
Further, the outer of cylindrical shell 1 bottom is equipped with ring flange 9, make things convenient for frock and valve docking and fixing, be provided with O-ring seal 10, enhance seal performance before the inwall of piston 4 and cylindrical shell 1.
Through bolt flange is connected with valve during pressure testing, in water injection hole, gets up with plug seal behind the injection water, through the handle rotating screw bolt; The promotion piston moves down; The empty G&W that is sealed between cylindrical shell and the valve produces pressure gradually, and passes to tensimeter to pressure, reach predetermined pressure after; Be the may observe valve situation of leaking, thereby realize pressure test valve.
Claims (3)
1. valve pressure measurement frock; Comprise cylindrical shell, the upper end closed of said cylindrical shell is characterized in that: have screw rod to pass the upper end of cylindrical shell from top to bottom and extend to the inside of cylindrical shell; Described screw rod cooperates with the inner thread of cylindrical shell; The upper end of screw rod has handle, and the lower end of screw rod is installed with the piston that can move up and down along cylinder inboard wall, is connected with spring between the medial surface of the upper end of said piston and cylindrical shell end; Described cylindrical shell is provided with two axially extending bores, and one of them axially extending bore is a water injection hole, and tensimeter is installed and be sealed with to the oral area of another axially extending bore.
2. valve pressure measurement frock according to claim 1 is characterized in that: the outer of said cylindrical shell bottom is equipped with ring flange.
3. valve pressure measurement frock according to claim 1 is characterized in that: be provided with O-ring seal before described piston and the cylinder inboard wall.
