Abstract
The utility model provides a type of 2-valve manifolds. The 2-valve manifolds comprise a main valve and a drain valve, wherein the main valve comprises a valve body, a valve cover, a valve clack, a valve rod and a level handle, the valve body is fixedly connected with the valve cover, the level handle is disposed on the valve rod, and the valve rod and the valve clack are of an integrated structure; and the valve body is provided with an integrated valve seat, opening and closing of the main valve are achieved by cooperation of the valve seat and the valve clack, and a sealing contact surface of the valve seat is equipped with a PTFE sealing gasket. Medium flow directions of input and output are controlled by the main valve of the 2-valve manifolds, and the drain valve is used for controlling a drain outlet, keeping the inside of the valves clean and releasing pressure. Forged steel is used for the valve body, and the PTFE sealing gasket is installed on the sealing contact surface between the valve seat processed by the valve body and the valve clack so as to ensure sealing reliability of the valve seat; and the valve rod is integrated with the valve clack, the valve body is integrated with the valve seat, and therefore the 2-valve manifolds are simple in structure and easy to machine.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of two valve groups.
Background technique
Two valve groups are comprised of valve body, valve gap, flap, valve seat, valve rod, pad, filler and a word handle conventionally.Valve body in two valve groups, the material of valve gap are case material (also claiming material of main part), and flap, valve seat, valve rod, sealing seat are usually called internals, also have in addition fastening piece, Sealing etc.But at present generally all there is the defects such as complex structure, sealing be poor in two traditional valve groups.
Model utility content
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of two valve groups of simple in structure, good airproof performance are provided.
The utility model is achieved by the following technical solution:
A kind of two valve groups, comprise main valve and blowdown valve, it is characterized in that, described main valve comprises valve body, valve gap, flap, valve rod and a word handle, and valve body is fixedly connected with valve gap, and a word handle is arranged on valve rod, described valve rod and flap are integral type structure, on described valve body, be provided with the valve seat of integral type, described valve seat coordinates and realizes the unlatching of main valve or close with flap, and PTFE sealing gasket is installed on the sealing contact surface of described valve seat.
Further setting of the present utility model is, described valve body is connected by internal thread with valve gap.
Further setting of the present utility model is, Packing seat, filler and Gland are housed on described valve gap.
Further setting of the present utility model is, is also provided with dust cover on described Gland.
The main valve control inputs of two valve groups described in the utility model and the MEDIA FLOW of output to; Blowdown valve control of sewage disposal mouth, the effect of the clean and pressure release in the inside of maintaining valve.Valve body adopts forged steel, on the sealing contact surface of flap and the valve seat processing with valve body self, PTFE sealing gasket is housed, to guarantee the reliability with the sealing of valve seat place, valve rod and flap are integral formula simultaneously, valve body and valve seat are integral formula, simple in structure, easy processing.
Accompanying drawing explanation
Fig. 1 is the left view of two valve groups described in the utility model;
Fig. 2 is the plan view of two valve groups described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, 2, the utility model provides a kind of two valve groups, comprises main valve and blowdown valve, the MEDIA FLOW of main valve control inputs and output to; Blowdown valve control of sewage disposal mouth, the effect of the clean and pressure release in the inside of maintaining valve.Described main valve comprises valve body 1, valve gap 3, flap, valve rod 8 and a word handle 9, valve body 1 is fixedly connected with valve gap 3, one word handle 9 is arranged on valve rod 8, described valve rod 8 is integral type structure with flap, on described valve body 1, be provided with the valve seat of integral type, described valve seat coordinates and realizes the unlatching of main valve or close with flap, and PTFE sealing gasket 2 is installed on the sealing contact surface of described valve seat.Preferably, described valve body 1 is connected by internal thread with valve gap 3, and this spline structure is more shown in simply.
Meanwhile, Packing seat 4, filler 5 and Gland 6 are housed on described valve gap 3, to guarantee the stable of sealability.On described Gland 6, be also provided with dust cover 7, for preventing that dust from entering.
When being installed, two valve group described in the utility model should make the flow direction of medium consistent with the direction of arrow on valve body.And need to follow following working service explanation:
1, according to the purposes of valve, select the basic structure of determining valve
2, according to the pressure of medium, temperature, corrosivity, whether containing material foreign material etc., select the materials of selected valves.
3, sign, the quality certification that must check on valve are installed and whether are met usage requirement.
4, the inner chamber of check valve and sealing surface, do not allowed dirt to adhere to.
5, check whether connecting bolt is evenly tightened.
6, check whether filler compresses, and should guarantee the sealing of filler, but not hinder the lifting of valve rod.
7, valve should be installed according to requirements, but convenience must note maintenance and operation time.
8, valve in use requires valve wide open or full cut-off, does not allow valve portion to be separately enabled as and to regulate stream.
Should be through the rotating part oiling of being everlasting when 9, valve is used, the oiling of valve rod trapezoidal thread part.
10, manually-operated gate, when unlatching or closing operation, should be used handwheel open and close, must not be by auxiliary lever or other instrument.
11, valve should be made regular check on after using, and checks that sealing surface, valve rod, filler and pad etc. have or not wearing and tearing.If damage, lost efficacy, and should repair in time or change.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and departed from scope of the present utility model.All so apparent modifications of the technician to described field, within being included in the scope of this claim.
