CN2278818Y - Timing self-closing stop valve - Google Patents

Abstract

The utility model relates to a novel timing self-closing stop valve which comprises a valve body and a valve cover. A button with a push rod is arranged at the valve mouth of the upper end of the valve body, and a piston, a timing rod, a spring and a timing base are respectively arranged in a cylinder sleeve at the lower side of a push rod. The utility model is characterized in that a time adjustment bolt is arranged at the lower part of the timing base, and the adjustment end of the time adjustment bolt is arranged at the outer side of the bottom of the valve body; a sealing pressing sheet which is in threaded connection with the valve cover is arranged between a top rod and the valve cover, and a stopping mouth connected by screw threads is arranged at the upper part of an inner cylinder sleeve and the inner part of the valve body. Because an adjustment mechanism of time delay self-closing is added on the valve body, the utility model has the advantages of reasonable structure, long service life, water saving, etc.

Description

Novel timing self-closing cut-off valve

The utility model belongs to valve class technical field, the timing self-closing cut-off valve of specifically a kind of civilian particularly common plunge bath special use.

At present, the valve that overwhelming majority bathing pool uses all is manually operated type stop valves, this stop valve no matter from performance still be working life its effect all not ideal, it is much constant particularly to bring for bathing pool in management, simultaneously also increased trouble to the user, often cause the running water phenomenon, so not only wasted water resources, increased bathing pool and user's expense simultaneously again.

The purpose of this utility model provides the timing self-closing cut-off valve that a kind of bathing pool uses.

The purpose of this utility model is achieved in that it includes the three way valve of a band inner cylinder liner, valve gap, be provided with the knob of a band push rod at valve port place, valve body upper end, downside at push rod is to be disposed with the piston of finishing deferred action in the inner cylinder liner, timing lever, spring, the timing base, it is characterized in that being fixedly connected with a timing bolt in the bottom of timing base, wherein the adjustable side of timing bolt is arranged on the outside of valve body bottom, the valve bottom of passing at the timing bolt is inlaid with a seal ring, between push rod and valve gap, be provided with a sealing compressing tablet that is threaded with valve gap, be provided with a seam that is threaded at the top and the valve inner of inner cylinder liner.

The utility model is owing to increased the time-setting mechanism of delay-self-closing on valve body, therefore has following advantage: rational in infrastructure, economical with materials, applied range, long service life, using water wisely, be specially adapted to public places such as shower cubicle, public lavatory, thus the generation of having stopped the perennial draingage phenomenon.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a half section structural representation of the present utility model

By shown in Figure 1, among the figure 1 is that three way valve, 4 is that valve gap, 9 is for being arranged on the inner cylinder liner in the valve body, be provided with the knob 2 of a band push rod 3 at valve port place, the upper end of valve body 1, downside at push rod 3 is to be disposed with piston 11, timing lever 13, spring 14, the timing base 15 of finishing deferred action in the inner cylinder liner 9, between piston and inner cylinder liner, be equipped with seal ring 12, be fixed with a sealed pressure pad 10 at the upper surface of piston.Be fixedly connected with a timing bolt 16 in the bottom of timing base 15, wherein the adjustable side of timing bolt is arranged on the outside of valve body 1 bottom, be inlaid with a seal ring 17 in the valve bottom that timing bolt 16 is passed, between push rod 3 and valve gap 4, be provided with a sealing compressing tablet 5 that is threaded with valve gap 4 and a seal ring 6, be provided with a seam that is threaded 7 in the top and the valve body inboard of inner cylinder liner 9.Under knob 2 usefulness hands, then push rod 8 promotion pistons 11 move down, spring is loaded and compress, the timing lever 13 that is connected below the piston is inserted regularly in the hole in limited time of base 15 thereupon, the water that makes 9 li of inner cylinder liners simultaneously by in limited time between hole and piston and the inner cylinder liner 9 the crease crack be forced out outside the inner cylinder liner, piston and sealed pressure pad 10 and seam 7 are thrown off makes aqueous medium pass through from the water passage hole 8 of inner cylinder liner and the slit between seam and the push rod, piston 11 produced certain pressure when WATER AS FLOW MEDIUM flows and made under the effect of piston at spring return rapidly, this is an one; It two also is most important, because the water of cylinder piston bottom is forced out, when popping up, form vacuum, so utilize the gap of hole area of contact size in limited time on timing lever and the base regularly and minute quantity to make water slowly enter the speed that limited piston moves up and prolong the shut-in time, even now, in time because the temperature of water is different, the molecule expansion coefficient is also different, be difficult to grasp the shut-in time, so at the use initial stage, rotate timing bolt 16 with screw-driver as required, making regularly, the position of base 15 changes, thereby changed area of contact and gap between timing base and the timing lever, therefore the shut-in time that is prolonged obtains changing.

Claims (2)

1, a kind of novel timing self-closing cut-off valve, it includes the three way valve of a band inner cylinder liner, valve gap, be provided with the knob of a band push rod at valve port place, valve body upper end, downside at push rod is to be disposed with the piston of finishing deferred action in the inner cylinder liner, timing lever, spring, the timing base, it is characterized in that being fixedly connected with a timing bolt in the bottom of timing base, wherein the adjustable side of timing bolt is arranged on the outside of valve body bottom, the valve bottom of passing at the timing bolt is inlaid with a seal ring, between push rod and valve gap, be provided with a sealing compressing tablet that is threaded with valve gap, be provided with a seam that is threaded at the top and the valve inner of inner cylinder liner.
