Abstract

The invention discloses a flange clamping chuck for a valve, which comprises a latch base, a latch and a rotary fixing bolt, wherein an arc-shaped groove is formed above the latch base; the rotary fixing bolt is positioned on the upper part in the center of the latch base; an extending block corresponding to the arc-shaped groove of the latch base is arranged on the lower part of the latch; the rotary fixing bolt passes through the extending block of the latch; and a baffle is arranged on one side of the latch. With the mode, the flange clamping chuck for the valve has a simple structure, is convenient and can reduce production cost.

Description

A kind of banjo clip of valve head that holds

Technical field

The present invention relates to frock clamp, the banjo clip that the relates in particular to valve head that holds.

Background technology

In industries such as chemical industry, boiler, pressure vessel, the valve of all kinds of forms such as safety valve, stop valve, gate valve uses very extensive.Because valve in use, sealing surface is subjected to the erosion of working medium for a long time, is subjected to the washing away of foreign matter in gas, the fluid, the often wearing and tearing of switch for a long time.The capital makes the flatness of valve sealing face impaired, causes valve leak, causes the waste and the economic loss of raw material.Therefore, abandon for fear of valve, cause waste, need grind valve sealing face, this just needs to use frock clamp clamping valve, more because of the valve pattern, have angle between valve sealing face that has and the valve seat planes, so valve clamp structure complexity, also there is not at present the banjo clip of the such valve head that holds, it is simple in structure, and is easy to use, can reduce production costs.

Summary of the invention

Technical problem to be solved by this invention is: a kind of banjo clip of the valve head that holds is provided, and the banjo clip of the valve of this kind valve header structure that holds is simple, easy to use, can reduce production costs.

Solve this technical problem, technical scheme of the present invention is: a kind of banjo clip of valve head that holds, it comprises latch seat, latch and rotation set bolt, the top of described latch seat has deep-slotted chip breaker, described rotation set bolt is positioned at latch seat central upper, the bottom of described latch has with latch seat deep-slotted chip breaker adapts stretches out piece, and described rotation set bolt passes the piece that stretches out of latch.

One side of described latch is provided with baffle plate.

Described latch is made up of arc clamp and the gear piece that removably connects.

The banjo clip of a kind of valve of the present invention hold the head adopt in such a way, simple in structure, easy to use, can reduce production costs.

Description of drawings

Below in conjunction with accompanying drawing the banjo clip of a kind of valve of the present invention head that holds is done an explanation in further detail;

Fig. 1 is the hold structural representation of head of the banjo clip of a kind of valve of the present invention;

Fig. 2 analyses and observe enlarged diagram for A-A shown in Figure 1;

In Fig. 1, Fig. 2, Fig. 3, Fig. 4,1, baffle plate; 2, latch seat; 3, rotation set bolt; 4, latch.

The specific embodiment

As shown in Figure 1 and Figure 2, the banjo clip of the valve head that holds comprises latch seat 2, latch 4, rotation set bolt 3 and baffle plate 1, the top of latch seat 2 has deep-slotted chip breaker, rotation set bolt 3 is positioned at latch seat 2 central upper, the bottom of latch 4 has with latch seat 2 deep-slotted chip breakers adapt stretches out piece, rotation set bolt 3 passes the piece that stretches out of latch 4, and baffle plate is installed on a side of latch 4, and latch 4 is made up of arc clamp and the gear piece that removably connects.Gear piece can be made the multiple specification that varies in size, and gear piece shown in Figure 3 is used for the little occasion of flange diameter of valve, and gear piece shown in Figure 4 can be used for the less occasion of flange diameter of valve.During use, at the structure of some valve, sealing surface and valve seat planes just can be rotated latch not on horizontal line, when rotating to suitable angle, fix with the rotation set bolt on the latch base.The banjo clip of the valve of the present invention header structure that holds is simple, easy to use, can reduce production costs.
