Abstract
The utility model provides a pressed type valve sealed by a membrane. Generally, a padding box, padding and a press cover are utilized to seal a valve rod and a valve cover of a valve, and water is prone to leak at the position of the valve rod for a long time under the water pressure. The pressed type valve sealed by the membrane is designed for water saving improvement of an existing flush toilet. The pressed type valve sealed by the membrane is structurally characterized in that the valve cover and a valve body are sealed through the membrane, and the valve rod is connected with and penetrates through the membrane to be sealed. The valve can be locked and fastened on equipment through a bolt, the valve body and the bolt can be integrated or separated, the valve is directly fixed in a fixing box and installed on the ground, and a valve cap press plate supported by a spring is positioned on the valve cap.
Description
Technical field
The utility model relates to a kind ofly presses the pressure type valve with diaphragm seal.
Background technology
Usually adopt bedding and padding case, bedding and padding, gland seal between the valve rod of valve and the valve gap, it is little to press the up and down resistance of pressure type valve requirement valve rod, when bonnet pressure is eliminated, valve rod is at spring action lower valve rod energy automatic-ascending, valve closing, therefore require gland can not press too tightly, leak easily but be in for a long time hydraulic pressure lower valve rod place, a kind ofly press the pressure type valve with diaphragm seal for addressing the above problem to design.On the other hand to existing toilet bowl energy-saving improvement and design a kind ofly press the pressure type valve with diaphragm seal.
Summary of the invention
The invention provides and a kind ofly press the pressure type valve with diaphragm seal, cancellation bedding and padding case, bedding and padding, gland seal between valve rod and the valve gap, and the employing diaphragm seal, prevented that valve is in the problem that hydraulic pressure lower valve rod place leaks easily for a long time, a kind ofly pressed the pressure type valve with diaphragm seal for having cooperated existing toilet bowl energy-saving improvement and design on the other hand.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pressure type valve of pressing with diaphragm seal comprises valve body, valve gap, spool, valve rod, adopts diaphragm seal between valve gap and valve body, and valve rod connects barrier film and passes barrier film.A kind of with diaphragm seal press the pressure type valve by bolt-locking be fixed on the equipment, valve body and bolt have disjunctor and split, a kind of pressure type valve of pressing with diaphragm seal that is fixed in the fixed bin arranges one by spring-supported bonnet pressing plate at bonnet.
The invention will be further described below in conjunction with drawings and Examples.

The specific embodiment
Fig. 1 a kind ofly presses pressure type valve (opening) valve body and bolt Split type structure schematic diagram with diaphragm seal, as shown in Figure 1, when external force pressure valve cap 3, bonnet 3 descends together with valve rod 4, valve open, tap water from valve water inlet interface 16 enter, through chamber 19 on chamber 18, valve core cavity 8, spool weep hole 9, the valve under the valve, chamber weep hole 20, valve exhalant canal 21 on the valve, discharge from valve water outlet mouthpiece 17.The valve below arranges a valve bolt hole 22 and is fixed on equipment for bolt 5.
Fig. 2 a kind ofly presses pressure type valve (closing) structural representation with diaphragm seal.As shown in Figure 2, when bonnet 3 pressures are eliminated because the effect of spring 1, bonnet 3 rises together with valve rod 4, valve stem packing ring 15 has sealed valve core cavity 8, has therefore blocked current, valve closing.Fig. 3 a kind ofly presses the signal of pressure type valve (closing) valve body and bolt conjoined structure with diaphragm seal.
Fig. 4 is that a kind of pressure type valve (closing) of pressing with diaphragm seal is installed in structural representation in the fixed bin, this is designed to cooperate existing toilet bowl energy-saving transformation a kind of be fixed on to be installed in the fixed bin groundly a kind ofly press the pressure type valve with diaphragm seal.
As shown in Figure 4, when excrements, the people rides on bonnet 3, valve open, and when excrements descendant pin left bonnet 3, bonnet 3 pressure disappeared, and bonnet 3 rises valve closing together with valve rod 4.
Fig. 5 is that a kind of pressure type valve (opening) of pressing with diaphragm seal is installed in the structural representation that the bonnet pressing plate is arranged in the fixed bin.
Fig. 6 is that a kind of pressure type valve (closing) of pressing with diaphragm seal is installed in the structural representation that the bonnet pressing plate is arranged in the fixed bin.
Shown in Figure 6 such as Fig. 5, the people rides on bonnet pressing plate 23 when excrements, and bonnet pressing plate 23, bonnet 3 descend together with valve rod 4, valve open, excrements descendant pin leaves bonnet pressing plate 23, and bonnet pressing plate 23 pressure disappear, bonnet pressing plate 23, bonnet 3 rise valve closing together with valve rod 4.
Above-mentioned a kind of suitable being used in of pressure type valve of pressing with diaphragm seal that is fixed in the fixed bin has the toilet bowl energy-saving transformation now.
