Abstract
The utility model discloses a valve pressure test clamp. A left baffle plate (3) and a right baffle plate (14) are connected integrally by using four bolt and nuts (15); a screw (4) penetrates through the center of the left baffle plate (3); a handle wheel (1) is fixed at the front end of the screw (4); a movable connector (6) and a fixed connector (7) are connected with the rear end of the screw (4); a left medium inlet/outlet connector (11) is installed on the excircle of the fixed connector (7); a left pressure test plug (9) is arranged inside the fixed connector in a mode of slide match; a plug internal O-shaped ring (8) and a plug external O-shaped ring (10) are arranged on the left pressure test plug (9); a right pressure test plug (13) is installed at the center of the right baffle plate (14); and a right medium inlet/outlet connector (12) is installed on the excircle of the right baffle plate (14). According to the valve pressure test clamp, two channels of a valve are clamped by two pressure test plugs in a mode of butt clamp through the hand wheel in a mode of screw transmission; one plug is used for supplying pressure and is observable, and the other end is sealed; when a valve gate is opened completely, the strength can be tested; and the valve pressure test clamp is simple in structure, convenient to install and dismantle, low in manufacturing cost and high in working efficiency.
Description
Technical field
The utility model relates to the grip device of various basic, normal, high pressure valve proof strengths and sealing property, is widely used in professional production petroleum products valve producer.
Background technology
At present; Known valve all must all carry out intensity and experiments of sealing performance according to international standard and national standard before dispatching from the factory, all be to use the gasket ring sealing, and two will connect with blind plate, a plurality of bolt, nut is wrenched; Use multiple parts to connect; Time-consuming, and rotate when compressing and decrease the gasket ring face of workpiece folder easily, sealing and intensity and inconvenience are observed in corresponding pressure testing opening and closing.
Summary of the invention
The purpose of the utility model is: a kind of valve pressure testing anchor clamps are provided, and simple in structure, install and remove easy to connectly, can in time change " O " type circle consumable accessory, reduce manufacturing cost, increase work efficiency.
The technical solution of the utility model is: these pressure testing anchor clamps comprise that handwheel, right baffle-plate, screw rod, active joint, fixture splice, left pressure testing plug, left medium are imported and exported joint, right medium is imported and exported joint, right pressure testing plug, right baffle plate and bolt and nut; Four bolt and nuts connect right baffle-plate and right baffle plates and screw and are combined into one; Screw rod passes the right baffle-plate center through acme thread; The front end of screw rod is with the fixing handwheel of key, and the rear end of screw rod connects active joint and fixture splice through the studding bolt, left medium is installed on the cylindrical of fixture splice is imported and exported joint; In fixture splice, slide and join left pressure testing plug; Establish " O " type circle and outer " O " type circle of plug in the plug on the left side pressure testing plug, right pressure testing plug is installed, right medium is installed on the cylindrical of right baffle plate is imported and exported joint in right its centre.
The utility model makes two pressure testing plugs to folder valve two passages through handwheel through screw drive, and " O " type circle on the pressure testing plug rises and seals circle in two passages, and generation elastic deformation trace moves and reaches seal channel through about the extruding of " O " type circle; An entrance pressure can be observed other end sealing; Open entirely when valve flashboard and can try intensity, simple in structure, mounting or dismounting are convenient; Low cost of manufacture, high efficiency.
