Problems solved by technology

During the assembly process of the valve front seal manual flat plate valve, due to the elastic force of the wave spring between the valve seat and the valve body, the distance between the two valve seats is smaller than the thickness of the valve plate, and it is difficult to install the valve plate to the valve smoothly and accurately. Inside the body (between the two valve seats), it is necessary to design a tool that can facilitate on-site valve assembly and be used for valve installation and fixed valve seats.

Embodiment Construction

[0012] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as Figure 1-2 As shown, the tool includes a thumb screw 1, a gasket cover 2, a round nut 3, a steel pipe 4, a pull rod 5, an elastic sleeve 6 and a cone 7. One end of the pull rod 5 is threaded at the center of the cone 7, and the cone 7 Set into the elastic sleeve 6, one end of the steel pipe 4 is connected with the elastic sleeve 6, the round nut 3 is screwed on the external thread of the steel pipe 4, the other end of the steel pipe 4 is covered with a gasket cover 2, and the other end of the tie rod 5 protrudes from the gasket cover 2 and screw on the thumb screw 1 to form a tool as a whole.

[0014] Wherein, the elastic sleeve 6 is cut from the cutting starting line to the left along the center line.

[0015] Wherein, the outer circle of the elastic sleeve 6 is provided with a boss.

[0016] Such as figure 2 As shown, in...

Abstract

The invention discloses a tool for installing and fixing a valve seat of a valve. The tool includes a butterfly screw (1), a gasket cover (2), a round nut (3), a steel pipe (4), a pull rod (5), an elastic sleeve ( 6) and the cone (7), one end of the tie rod (5) is screwed to the center of the cone (7), the cone (7) is inserted into the elastic sleeve (6), and one end of the steel pipe (4) is connected to the elastic sleeve (6) ), the round nut (3) is screwed on the external thread of the steel pipe (4), the other end of the steel pipe (4) is covered with the gasket cover (2), and the other end of the tie rod (5) protrudes from the gasket cover (2) And screw on thumb screw (1), integrally constitutes tool. The invention has the advantages of simple structure, easy understanding and convenient operation, thereby greatly improving the assembly efficiency of the valve.

Description

technical field [0001] The invention relates to an assembly tool, in particular to a tool for fixing the valve seat of a valve with a wave spring after the valve seat is installed. Background technique [0002] Valves are control elements in fluid delivery systems such as petroleum, chemical industry, long-distance pipelines, various low-temperature projects, and marine oil production. The front seal manual flat valve refers to the valve in which the closing part moves the switch along the vertical direction of the channel center line, and is one of the most widely used valves at present. At present, there is a large demand for valve front seal manual flat plate valves in the market, and it is imperative to improve the production and assembly efficiency of valves. During the assembly process of the valve front seal manual flat plate valve, due to the elastic force of the wave spring between the valve seat and the valve body, the distance between the two valve seats is small...
