Abstract
The invention relates to an engineering valve. The engineering valve comprises a diaphragm cavity upper body, wherein the diaphragm cavity upper body is connected with a diaphragm cavity lower body, the upper end of the diaphragm cavity upper body is provided with a pressure inlet, one side of the diaphragm cavity lower body is provided with a liquid inlet hole, the other side of the diaphragm cavity lower body is provided with a liquid draining hole, the lower side of the pressure inlet is provided with a pushing block, the pushing block is connected with a diaphragm, the pushing block is connected with a valve rod, a reset spring is arranged on the valve rod, a sealing cartridge, a sealing ring and a sealing layer are arranged between the valve rod and the diaphragm cavity lower body, the bottom of the valve rod is provided with a sealing valve element, and a sealing pad is arranged in the diaphragm cavity lower body. When the engineering valve is used, load is applied from the pressure inlet, the pushing block is pushed to move downwards through the diaphragm, the valve rod is driven to move downwards, and the sealing of the sealing valve element is realized. In this way, required external pressure is small. Besides, when the engineering valve needs to be opened, rapid resetting can be realized under the action of the reset spring, the opening of the valve is realized, and engineering requirements are met.
Description
Technical field
The present invention relates to field of engineering technology, more particularly, to a kind of engineering valve.
Background technology
Engineering is science and certain application of mathematics, by this application, enables the material of nature and the characteristic of the energy
Enough by various structures, machine, product, system and process, it is that few manpower makes efficient, reliability with time the shortest and essence
And the thing useful to the mankind.Natural science applied theory is applied to the total of each subject formed in concrete industrial and agricultural production department
Claim.
Valve is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief.
For the valve of fluid control systems, used each to extremely complex robot control system(RCS) from simplest stop valve
Plant valve, its kind and specification are quite various.Valve can be used for controlling empty gas and water, steam, various Korrosionsmedium, mud, oil
The flowing of all kinds fluid such as product, liquid metal and radiating medium.Valve is also divided into cast iron valve, cast-steel valve according to material
Door, stainless valve (201,304,316 etc.), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard
The valve material such as customized.
Existing valve mechanism is complicated, and the external force of required input is larger, such troublesome poeration, and sealing is poor,
It is difficult to meet engineering demand.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, there is provided a kind of engineering valve.
The present invention is to be achieved through the following technical solutions：
A kind of engineering valve, including film room upper body, described film room upper body is connected with film room lower body, described film room upper body upper end
It is provided with pressure entrance, described film room lower body side is provided with inlet opening, and opposite side is provided with outage, under described pressure entrance
Side is provided with pushing block, and described pushing block is connected with diaphragm, and described pushing block is connected with valve rod, and described valve rod is provided with returning spring,
It is provided with sealing shroud, sealing ring and sealant, described stem bottom is provided with sealed valve core between described valve rod and film room lower body,
Described film room lower body is internally provided with sealing gasket.
As the preferred technical solution of the present invention, it is fixedly connected between described pushing block and valve rod.
As the preferred technical solution of the present invention, it is to be fastenedly connected between described sealing shroud and valve rod.
As the preferred technical solution of the present invention, described sealed valve core is in coniform.
Compared with prior art, the invention has the beneficial effects as follows：Present configuration is simple, reasonable in design, and the present invention is led to
Cross setting pushing block, diaphragm, valve rod, returning spring, sealing shroud, sealing ring and sealant, so when using, from pressure entrance plus
Enter load, promote pushing block to move down through diaphragm, band ovable valve stem moves down, and realizes the sealing of sealed valve core, so required
The ambient pressure wanted is little, and when needing to open, can realize Quick-return, realize beating of valve in the presence of returning spring
Open, and there is in the presence of sealing shroud, sealing ring and sealant preferable sealing, meet the demand of engineering.
