“diaphragms”可以造什么句，diaphragms造句

Since blocked diaphragms have a greater concentration of fasteners around the perimeter of each sheathing element, blocked diaphragms provide greater shear capacities than unblocked diaphragms.

These diaphragms prevent leakage along the valve stem.

Operating Principle: The diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem separated by non perforated diaphragms. These diaphragms prevent leakage along the valve stem .

The present work is expected to be useful for design of corrugated diaphragms.

This is accomplished by piercing the diaphragms and mechanically connecting the upper and lower stems.

When two corrugated diaphragms are joined at the outer edges, the unit is referred to as a capsule .

The replacement of elastomeric seals with metal diaphragms gives this valve superior leak integrity to the atmosphere.

Valve Advantages: The replacement of elastomeric packings by metal diaphragms gives this valve superior leak integrity at the top works of the valve and stem.

The valve has a threaded leak check port located on the side of the valve. This allows the diaphragms to be leak checked.

The upper stem is threaded into the diaphragm retainer nut. When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat.

Trials have been conducted on the effectiveness of women-initiated prevention methods, such as microbicides and diaphragms, and preventative drugs that can be used by both men and women.

The diaphragms may be flat or corrugated.

Study on diaphragms effect of cold-formed steel portal frame

With the X-frames projecting into the boxes, the transverse diaphragms were formed.

Gapacifive posts and diaphragms in a rectangular waveguide are analyzed in this paper by using the method of moments.

When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat.

The metal diaphragms act as the seal at the top of the valve. The primary improvement in this generation of valves is the elimination of the spring used to open the valve.

This finishing operation is omitted on bodies receiving rubber diaphragms.

In addition the recognized principles of stiffening by diaphragms and improved framing to provide continuity were specified.

Traditional analyses for inductive diaphragms and strips in rectangular waveguides have been restricted to the case of perfectly conducting metal sheets.

Reciprocating plunger seals have been substitute by mechanically or hydraulically actuated diaphragms in diaphragm pumps.

Leaks can occur along the valve stem through the packing or diaphragms. Leaks of this type can be stopped by closing the valve and venting any pressure from the outlet.

The physical process is that the diaphragms loosen up through use and eventually reach a point that could be considered final.
